[Purpose] The aim of this study was to examine the immediate effects of neuromuscular joint facilitation (NJF) on the functional activity level after rehabilitation of anterior cruciate ligament (ACL) reconstruction. [Subjects and Methods] Ten young subjects (8 males and 2 females) who underwent ACL reconstruction were included in the study. The subjects were divided into two groups, namely, knee joint extension muscle strength training (MST) group and knee joint extension outside rotation pattern of NJF group. Extension strength was measured in both groups before and after the experiment. Surface electromyography (sEMG) of the vastus medialis and vastus lateralis muscles and joint position error (JPE) test of the knee joint were also conducted. [Results] JPE test results and extension strength measurements in the NJF group were improved compared with those in the MST group. Moreover, the average discharge of the vastus medialis and vastus lateralis muscles on sEMG in the NJF group was significantly increased after MST and NJF treatments. [Conclusion] The obtained results suggest that NJF training in patients with ACL reconstruction can improve knee proprioception ability and muscle strength. © 2016 The Society of Physical Therapy Science.

Objectives: Although there are many reports about the risk of breast cancer, few have reported clinical factors including history of breast-related or other diseases that affect the prevalence of breast cancer. This study explores these risk factors for breast cancer cases reported in Beijing in 2009. Materials and Methods: Data were derived from a Beijing breast cancer screening performed in 2009, of 568,000 women, from 16 districts of Beijing, all aged between 40 and 60 years. In this study, multilevel statistical modeling was used to identify clinical factors that affect the prevalence of breast cancer and to provide more reliable evidence for clinical diagnostics by using screening data. Results and Conclusion: Those women who had organ transplants, compared with those with none, were associated with breast cancer with an odds ratio (OR) = 65.352 [95% confidence interval (CI): 8.488-503.165] and those with solid breast mass compared with none had OR = 1.384 (95% CI: 1.022-1.873). Malignant tendency was strongly associated with increased risk of breast cancer, OR = 207.999(95% CI: 151.950-284.721). The risk of breast cancer increased with age, OR1 = 2.759 (95% CI: 1.837-4.144, 56-60 vs. 40-45), OR2 = 2.047 (95% CI: 1.394-3.077, 51-55 vs. 40-45), OR3 = 1.668 (95% CI: 1.145-2.431). Normal results of B ultrasonic examination show a lower risk among participants, OR= 0.136 (95% CI: 0.085-0.218). Those women with ductal papilloma compared with none were associated with breast cancer, OR=6.524 (95% CI: 1.871-22.746). Therefore, this study suggests that clinical doctors should pay attention to these high-risk factors.

Objective-To evaluate the usefulness of a fasting plasma glucose (FPG) at 24-28 weeks' gestation to screen for gestational diabetes mellitus (GDM). Research design and methods-The medical records and results of a 75-g 2-h oral glucose tolerance test (OGTT) of 24,854 pregnant women without known pre-GDM attending prenatal clinics in 15 hospitals in China were examined. ResultsFPG cutoff value of 5.1 mmol/L identified 3,149 (12.1%) pregnant women with GDM. FPG cutoff value of 4.4 mmol/L ruled out GDM in 15,369 (38.2%) women. With use of this cutoff point, 12.2% of patients with mild GDM will be missed. The positive predictive value is 0.322, and the negative predictive value is 0.928. Conclusions-FPG at 24-28 weeks' gestation could be used as a screening test to identify GDM patients in low-resource regions. Women with an FPG between ≥4.4 and #5.0 mmol/L would require a 75-g OGTT to diagnose GDM. This would help to avoid approximately one-half (50.3%) of the formal 75-g OGTTs in China. © 2013 by the American Diabetes Association.

OBJECTIVE: A multicenter clinical trial was performed to evaluate and validate the performance of Cervista HPV HR test and to establish its effectiveness in identifying women at risk of having cervical intraepithelial neoplasia 2 (CIN 2) or higher grade (CIN 2+) in the Chinese population. MATERIALS AND METHODS: Residual ThinPrep Pap Test samples from women who are negative for intraepithelial lesion or malignancy (NILM) and atypical squamous cells of undetermined significance (ASCUS) or higher grade cytology were tested for high-risk human papillomavirus (HPV). The HPV test results were compared with histology results to determine the clinical sensitivity, specificity, positive predictive value, and negative predictive value of Cervista HPV HR for CIN 2+. The analytical accuracy of Cervista HPV HR compared with consensus HPV L1 polymerase chain reaction (PCR)/sequencing was also determined. RESULT: A total of 1,064 subjects were enrolled, including 544 with NILM cytology and 520 with ASCUS or higher grade cytology. Complete data sets including cytology, high-risk HPV test, colposcopy, and histology results for all subjects with ASCUS or higher grade were included in the analysis. The positive rate of Cervista HPV HR was 12.5% in patients with NILM and 69.04% in patients with ASCUS or higher grade. The overall percentage agreement between Cervista HPV HR and PCR with bidirectional sequencing was 86.26%, with positive percentage agreement and negative percentage agreement being 93.4% and 83.3%, respectively. In the overall population, the Cervista HPV HR positivity rate was 38.96% compared with 29.08% for PCR/sequencing. The clinical sensitivity and specificity for CIN 2+ of Cervista HPV HR were 98.50% and 68.21%, respectively. The negative and positive predictive values were 99.69% and 30.68%, respectively. CONCLUSIONS: The Cervista HPV HR test, performed on ThinPrep Pap Test samples, has the clinical performance characteristics required by China for use as part of routine cervical cancer screening. © 2012, American Society for Colposcopy and Cervical Pathology.

Injectable hydrogels with pH and temperature triggered drug release capability were synthesized based on biocompatible glycol chitosan and benzaldehyde-capped poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) (PEO-PPO-PEO). Aqueous solutions of the above polymers formed hydrogel under physiological conditions, allowing a desirable injectability, through the formation covalent benzoic-imine bond with pH and temperature changes. Rheological characterization demonstrated that the gelation rate and the moduli of the hydrogels were able to be tuned with chemical composition as well as pH and temperature of the polymer solution. Both hydrophobic and hydrophilic drugs could be incorporated inside the hydrogel through the in situ gel forming process and undergo a controlled release by altering pH or temperature. In vivo tests proved the formation and biocompatibility of the hydrogel in rat model. © 2010 American Chemical Society.

Glucose homeostasis is a trait of healthy ageing and is crucial to the elderly, but less consideration has been given to the age composition in most studies involving genetics and hyperglycemia.Seven variants in FOXO3 were genotyped in three cohorts (n = 2037; LLI, MI_S and MI_N; mean age: 92.5 3.6, 45.9 8.2 and 46.8 10.3, respectively) to compare the contribution of FOXO3 to fasting hyperglycemia (FH) between long-lived individuals (LLI, aged over 90 years) and middle-aged subjects (aged from 35-65 years).A different genetic predisposition of FOXO3 alleles to FH was observed between LLI and both of two middle-aged cohorts. In the LLI cohort, the longevity beneficial alleles of three variants with the haplotype AGGC in block 1 were significantly protective to FH, fasting glucose, hemoglobin A1C and HOMA-IR. Notably, combining multifactor dimensionality reduction and logistic regression, we identified a significant 3-factor interaction model (rs2802288, rs2802292 and moderate physical activity) associated with lower FH risk. However, not all of the findings were replicated in the two middle-aged cohorts.Our data provides a novel insight into the inconsistent genetic determinants between middle-aged and LLI subjects. FOXO3 might act as a shared genetic predisposition to hyperglycemia and lifespan.

Forkhead box class O (FOXO) transcription factors play a crucial role in longevity across species. Several polymorphisms in FOXO3 were previously reported to be associated with human longevity. However, only one Chinese replication study has been performed so far. To verify the role of FOXO3 in southern Chinese in the Red River Basin, a community-based case-control study was conducted, and seven polymorphisms were genotyped in 1336 participants, followed by a meta-analysis of eight case-control studies that included 5327 longevity cases and 4608 controls. In our case-control study, we found rs2802288*A and rs2802292*G were beneficial to longevity after Bonferroni correction (pallele = 0.005, OR = 1.266; pallele = 0.026, OR = 1.207). In addition, in the longevity group, carriers with rs2802288*A and rs2802292*G presented reduced HbA1c (p = 0.001), and homozygotes of rs2802292*GG presented improved HOMA-IR (p = 0.014). The meta-analysis further revealed the overall contribution of rs2802288*A and rs2802292*G to longevity. However, our stratified analysis revealed that rs2802292*G might act more strongly in Asians than Europeans, for enhancement of longevity. In conclusion, our study provides convincing evidence for a significant association between the rs2802288*A and rs2802292*G gene variants in FOXO3 and human longevity, and adds the Southern Chinese in the Red River Basin to the growing number of human replication populations.

Background Almost all reported fluorescence in situ hybridization (FISH) kits for prenatal diagnosis use probes from foreign (non-Chinese) countries. The aim of this study was to analyze the reliability of domestic (Chinese) FISH probe sets to detect aneuploidies of chromosomes 13, 18, 21, X, and Y related to prenatal diagnosis in 4210 cases. Methods Cytogenetic karyotyping was carried out as a standard prenatal diagnostic test, and amniotic fluid cell interphase FISH analysis was performed using two sets of probes (centromeric probes for chromosomes 18, X, and Y, and locus-specific probes for chromosomes 13 and 21) provided by GP Medical Technologies, Beijing, China. Then we compared the two results and found the performance characteristics for informative FISH results of aneuploidies by the domestic kit probes. Results In 4210 cases, 4126 cases generated karyotype results and 133 abnormal karyotypes (including 97 aneuploidies) were found. The FISH results of 98 cases (among them, 31 cases gave normal cytogenetic results) were uninformative. The rate of abnormal cases was 3.2% (133/4126). For the abnormal karyotypes, the rate of aneuploidy was 72.9% (97/133). Among the 97 aneuploidies, there were 58 cases of trisomy 21 (58/97, 59.8%), four cases of trisomy 13, 23 cases of trisomy 18, and 12 cases of sex chromosomal aneuploidies. The total concordance of the two methods was 97.9% (95/97; two cases were mosaics that had a low percentage of abnormal cells), and the concordance of trisomy 21, 13, and 18 by the two methods was 100%. Conclusions The two sets of the domestic FISH kit probes are reliable for prenatal diagnosis. The results demonstrate that FISH is a rapid and accurate clinical method for prenatal identification of chromosome aneuploidies.

Aims: Persistent Cesarean scar pregnancy (PCSP) is a rare and special type of Cesarean scar pregnancy (CSP) which is resistant to conservative treatment. The treatment option is challenging. We report a case series to provide indications for further treatment. Methods: Ten women diagnosed as having a PCSP, seeking better treatment because of primary treatment failure, were admitted to a gynecologic minimally invasive center. Ultrasound combined with office hysteroscopy was used for preoperative evaluation, and then a further surgical strategy was selected. Clinical data were retrospectively studied. Results: Among ten PCSP patients, 4 were type I and 6 were type II. In the 4 type I cases, 2 were treated by laparoscopy and the other 2 by hysteroscopy; to stop bleeding in 1 of them, the uterine artery was occluded laparoscopically. All type II cases were successfully treated by laparoscopic excision. The mean operating time was 61.5 min. The mean blood loss was 83.5 ml. No complications occurred except one intraoperative hemorrage. Conclusions: Experience from this case series indicates that an individualized surgical plan based on a full preoperative evaluation provides useful information for choosing a suitable treatment for PCSP. Endoscopically guided surgical excision with experienced hands may be considered the most useful treatment. Copyright © 2012 S. Karger AG, Basel.

Objective: To study the expression of nociceptin in adenomyosis tissue and understand its relationship with the severity of dysmenorrhea. Methods: The myometrial specimens were collected from 55 patients undergoing hysterectomy at our hospital during December 2007 and June 2008. Their mean age was 41-52 years old. There were 34 adenomyosis patients in case group and 21 other patients in control group. Immunohistochemical staining was employed to detect nociceptin in eutopic endometrium and ectopic endometrial tissues in case group and normal endometrium and myometrial tissues in control group. Results: The expression of nociceptin was significantly higher in the eutopic endometrial tissue (7.1 ± 1.7) of case group than those in endometrial (2.7 ± 2.0) and myometrial tissues of control group (P < 0.05); The expression of nociceptin was higher in the eutopic endometrial tissue (7.4 ± 1.5) of dysmenorrhea group than that of non-dysmenorrhea group (5.0 ± 1.2) in case group (P < 0.05); The expression of nociceptin in eutopic endometrium and myometrium was the highest in severe dysmenorrhea group (8.4 ± 1.3). And the non-dysmenorrhea and mild dysmenorrheal groups had no significant differences [(5.0 ± 1.2) vs (6.8 ± 1.4)]. And it decreased gradually in moderate dysmenorrhea, mild dysmenorrhea and non-dysmenorrhea groups. Conclusion: A high expression of nociceptin in adenomyosis may be one of the casual factors of dysmenorrhea. The severity of dysmenorrhea is positively correlated with the expression of nociceptin in eutopic endometrial tissue in case group (r = 0.515, P = 0.034) and ectopic endometrium tissue. And the endometrial expression of nociceptin may be monitored dynamically to track the development of adenomyosis. © 2011 by the Chinese Medical Association.
