Transgenerational associations of parental famine exposure in early life with offspring risk of adult obesity in China.

OBJECTIVE: The aim of this study was to investigate the transgenerational associations between exposure to famine in early life and obesity. METHODS: This study used the longitudinal data from the China Health and Nutrition Survey from 1989 to 2015. A total of 1113 fathers and 1207 mothers (946 mother-father pairs) born in 1955 to 1966 and 1895 adult offspring were included. Offspring were classified into subgroups according to the famine exposure of their parents (unexposed, maternal exposed, paternal exposed, parental exposed) and exposure timing (during fetal development, childhood). RESULTS: Maternal exposure to famine in early life was associated with elevated levels of BMI, waist circumference, overweight, and central obesity of their children, whereas paternal exposure was inversely associated with these measurements. Compared with children of unexposed parents (P0M0), the maternal exposed group (P0M1) had higher mean BMI, by 1.3 kg/m2 (95% CI: 0.3 to 2.4); waist circumference, by 1.5 cm (-1.0 to 3.9); overweight (odds ratio [OR] [95% CI]: 3.1 [1.6 to 6.1]); and central obesity (OR [95% CI]: 1.9 [1.02 to 3.7]). No significant heterogeneity was observed in the associations by sex of offspring. CONCLUSIONS: Fetal and early childhood exposure to famine in parents may be associated with their children's risk of obesity during adulthood. A better understanding of the transgenerational associations is important for developing strategies to reduce obesity risk in future generations.

Differential physiological, transcriptomic and metabolomic responses of Arabidopsis leaves under prolonged warming and heat shock.

BACKGROUND: Elevated temperature as a result of global climate warming, either in form of sudden heatwave (heat shock) or prolonged warming, has profound effects on the growth and development of plants. However, how plants differentially respond to these two forms of elevated temperatures is largely unknown. Here we have therefore performed a comprehensive comparison of multi-level responses of Arabidopsis leaves to heat shock and prolonged warming. RESULTS: The plant responded to prolonged warming through decreased stomatal conductance, and to heat shock by increased transpiration. In carbon metabolism, the glycolysis pathway was enhanced while the tricarboxylic acid (TCA) cycle was inhibited under prolonged warming, and heat shock significantly limited the conversion of pyruvate into acetyl coenzyme A. The cellular concentration of hydrogen peroxide (H2O2) and the activities of antioxidant enzymes were increased under both conditions but exhibited a higher induction under heat shock. Interestingly, the transcription factors, class A1 heat shock factors (HSFA1s) and dehydration responsive element-binding proteins (DREBs), were up-regulated under heat shock, whereas with prolonged warming, other abiotic stress response pathways, especially basic leucine zipper factors (bZIPs) were up-regulated instead. CONCLUSIONS: Our findings reveal that Arabidopsis exhibits different response patterns under heat shock versus prolonged warming, and plants employ distinctly different response strategies to combat these two types of thermal stress.

Colorectal Cancer Screening Modalities in Chinese Population: Practice and Lessons in Pudong New Area of Shanghai, China.

Background: Parallel test of risk stratification and two-sample qualitative fecal immunochemical tests (FITs) are used to screen colorectal cancer (CRC) in Shanghai, China. This study was designed to identify an optimal initial screening modality based on available data. Methods: A total of 538,278 eligible residents participated in the program during the period of January 2013 to June 2017. Incident CRC was collected through program reporting system and by record linkage with the Shanghai Cancer Registry up to December 2017. Logistic regression model was applied to identify significant factors to calculate risk score for CRC. Cutoff points of risk score were determined based on Youden index and defined specificity. Sensitivity, specificity, and positive predictive values (PPVs) were computed to evaluate validity of assumed screening modalities. Results: A total of 446 CRC were screen-detected, and 777 interval or missed cases were identified through record linkage. The risk score system had an optimal cutoff point of 19 and performed better in detecting CRC and predicting long-term CRC risk than did the risk stratification. When using a cutoff point of 24, parallel test of risk score, and FIT were expected to avoid 56 interval CRCs with minimal decrease in PPV and increase in colonoscopy. However, the observed detection rates were much lower than those expected due to low compliance to colonoscopy. Conclusions: Risk score is superior to risk stratification used in the program, particularly when combined with FIT. Compliance to colonoscopy should be improved to guarantee the effectiveness of CRC screening in the population.

[A case-control study on the treatment of carpal tunnel syndrome with needle Dao].

OBJECTIVE: To study clinical effects of needle Dao for the treatment of carpal tunnel syndrome. METHODS: From July 2014 to December 2016, 60 patients with carpal tunnel syndrome were divided into two groups: needle Dao treatment group(treatment group), and brace and medicine treatment group(control group), 30 cases in each group. There were 8 males and 22 females in the treatment group, with an average age of (49.38±7.43) years old. There were 7 males and 23 females in the control group, with an average age of (50.23±8.71) years old. There were no statistically significant differences between two groups before treatment in age, sex, course of disease, sensory nerve conduction velocity (SCV), sensory nerve action potential (SNAP), and distal motor latency(DML). The patients in the treatment group were treated with needle Dao for 1 to 2 times, while the patients in the control group were given celecoxib, vitamin B1 and vitamin B12, with the brace fixed. After treatment, the changes of SCV, SNAP and DML in two groups were observed. RESULTS: After treatment, the SCV were (48.63±7.33) m/s and (41.24±6.15) m/s in treatment group and control group separately, the SNAP were (9.89±3.71) m/s and (8.22±2.19) m/s, and the DML were(5.11±2.28) m/s and (6.13±2.23) m/s. The SCV, SNAP and DML after treatment were better than those before treatment(P<0.05). And the results of SCV, SNAP and DML of patients in the treatment group were better than those of patients in the control group(P<0.001). CONCLUSIONS: Needle Dao can effectively improve the overall treatment efficiency of patients with carpal tunnel syndrome and reduce the symptoms of patients, which is feasible and suitable to use in clinical.

A systematic review of cross-cultural adaptation of the neck disability index.

STUDY DESIGN: Systematic review of cross-cultural adaptation. OBJECTIVE: To perform a systematic review of cross-cultural adaptations of the Neck Disability Index (NDI) and to give a critical assessment to improve its translation. SUMMARY OF BACKGROUND DATA: The NDI is used to assess functional capacity and physical activity in patients with neck pain, but the quality of its cross-cultural adaptations has not been systematically reviewed. METHODS: PubMed, Cochrane Library, and EMBASE were searched up through 2013 to identify studies of cross-cultural NDI adaptations. Search terms were "Neck Disability Index" or "NDI" and "cross-cultur*" or "cultur*" or "valid*" or "equivalence" or "transl*." Data were extracted and study quality was assessed. RESULTS: Twenty-four different NDI versions were identified from 14 different languages/cultures. Most reported forward and back translation and pretesting, but sample size was a problem for most studies. The Cronbach α was generally acceptable, and 13 versions met the criterion of reliability by reporting an intraclass correlation coefficient of 0.70 or more, although some versions did not reach the minimal intraclass correlation coefficient. Eleven versions tested ceiling and floor effects, but only 1 Japanese version reported a floor effect. No study reported interpretability, and none provided the minimal important change or minimal important difference. CONCLUSION: The Arabic, Italian, and Thai versions were of higher quality than the other versions according to the overall assessment of the 3 checklists. The Catalan, Chinese, Japanese, Korean, Thai, and Turkish versions need more research according to the Quality Criteria for Psychometric Properties of Health Status Questionnaire. Pretest sample size was not large enough in most cases. LEVEL OF EVIDENCE: 1.

Systematic review of randomized clinical trials of acupressure therapy for primary dysmenorrhea.

The evidence of acupressure is limited in the management of dysmenorrhea. To evaluate the efficacy of acupressure in the treatment of primary dysmenorrhea based on randomized controlled trials (RCTs), we searched MEDLINE, the Chinese Biomedical Database (CBM), and the Cochrane Central Register of Controlled Trials (CENTRAL) databases from inception until March 2012. Two reviewers independently selected articles and extracted data. Statistical analysis was performed with RevMan 5.1 software. Eight RCTs were identified from the retrieved 224 relevant records. Acupressure improved pain measured with VAS (-1.41 cm 95% CI [-1.61, -1.21]), SF-MPQ at the 3-month followup (WMD -2.33, 95% CI [-4.11, -0.54]) and 6-month followup (WMD -4.67, 95% CI [-7.30, -2.04]), and MDQ at the 3-month followup (WMD -2.31, 95% CI [-3.74, -0.87]) and 6-month followup (WMD -4.67, 95% CI [-7.30, -2.04]). All trials did not report adverse events. These results were limited by the methodological flaws of trials.

Acupuncture for chronic Achilles tendnopathy: a randomized controlled study.

OBJECTIVE: To examine whether acupuncture treatment would improve outcome in chronic Achilles tendinopathy. METHODS: A randomized, controlled trial at two centers of 64 randomized patients aged 18 to 70 years with chronic Achilles tendinopathy was conducted from July 2007 to April 2010, with follow-up until October, 2010. These patients were randomly allocated into an acupuncture treatment group (acupuncture group) and an eccentric exercises group (control group). The validated Victorian Institute of Sports Assessment-Achilles (VISA-A) questionnaire was completed at baseline and 8, 16, and 24 weeks. The pain at rest and after activity was accessed at baseline and 8 weeks with Visual Analogue Scale (VAS). RESULTS: After randomization into the acupuncture group or control group, one patient was loss of follow-up. The mean VISA-A score improved signifificantly after 8 weeks in the acupuncture group to 67.1 points [95% confifidence interval (CI), 64.1-70.2] and in the control group to 48.5 points (95% CI, 45.5-51.6) with an additional 18.6 points increase in acupuncture treatment patients (P=0.0000). Acupuncture treatment resulted in a significant increase from baseline in VISA-A of 25.8 after 16 weeks and 28.4 after 24 weeks. Whereas, in the control group the increase from baseline in VISA-A were 10.0 and 16.6 after 16 and 24 weeks, respectively (P=0.0000). The VAS diminished by 2.0 cm after activity, and by 1.5 cm at rest after 8 weeks in the control group. In the acupuncture group, the pain scores diminished significantly more than in the control group, with pain reduction of 3.7 cm after activity (P=0.0000) and 3.2 cm at rest (P =0.0000). CONCLUSION: Acupuncture intervention could improve pain and activity in patients with chronic Achilles tendinopathy compared with eccentric exercises.

Meridian essence: modern thought.

Meridian essence has been investigated through anatomy, electrophysiology, biophysics, and biochemistry. Various hypotheses of meridian essence exist, but no hypothesis can truly reflect the internal character of Chinese medicine (CM). The research of meridian essence requires a holistic viewpoint and innovative awareness. Initially, any hypothesis regarding meridian essence should begin with observation of the human body. Secondly, the research should arise from the meridians' physical functions and pathological changes, so as to maintain the fundamental nature of the meridians themselves. Thirdly, the research should be based upon the theory of CM, yet coupled with the integration of modern techniques to deepen our understanding of the scientific contents of meridians. Fourthly, theoretical research should be combined closely with clinical practice, in order to test the achievements in actual conditions. Lastly, more attention should be given to negative results in studies to more accurately discover the real essence of meridians.
