Objective: To select the common syndrome factors of menopausal syndrome through questionnaire investigation among experts. Methods: Firstly, a questionnaire was constructed on the basis of our previous research, and then investigation of the experts by the questionnaire was carried out. The experts came from twelve tertiary hospitals (6 cities) in China, and engaged in clinical practice of gynecology of traditional Chinese medicine (TCM) or integrated traditional Chinese and Western medicine. The common TCM syndrome factors of menopausal syndrome were selected based on consent degree of the experts in mean value, full marks ratio, rank sum and variation coefficient. Results: One hundred sets of the questionnaires were sent out and ninety-eight sets were returned back. The callback rate was 98%. In accordance with cumulative percentage of expert agreement and complete agreement more than 50% and the coefficient variation less than 0.25, we confirmed the common TCM syndrome factors of menopause syndrome. The syndrome factors related to disease location were kidney, liver, heart, and spleen, and those related to the nature of disease were yin deficiency, deficiency of essence, yang deficiency, hyperactivity of yang, qi deficiency, qi stagnation, blood deficiency, and blood stasis. Conclusion: Expert consultation questionnaire can collect consensus opinions of experts and is effective for identifying common TCM syndrome factors of a disease. The TCM syndrome factors acquired through the study may provide the evidence for establishment of TCM syndrome diagnosis criteria for the disease in future.

Objective To investigate the relationship between positive experience and perceived social support of the parents with a cerebral palsy child. Methods 105 parents with a cerebral palsy child who were hospitalized in the Third Affiliated Hospital of Zhengzhou University between November , 2014 and January , 2015 were conveniently selected and investigated about their positive experience and perceived social support with general information questionnaire, positive aspects of caregiving and perceived social support scale. The correlation between the two was analyzed. Results The mean score of the parent′s positive experience was (30.82 ± 5.26); the dimension of self affirmation was (16.71 ± 3.06) and the dimension of life expectation was (14.10 ± 2.85). The scores of the parents′ positive experience were significantly different among gender, education of parents and the age,gender of children. The score of the parents′ positive experience was positively correlated with the total score of perceived social support (r = 0.214, P = 0.029) and the score of other support (r = 0.227, P = 0.020). Conclusions The parents′ positive experience was medium of the high level, which is worth of more attention in order to improve it. The higher perceived social support score is , the more positive experience parents will have.

Objective To investigate the relationship between family cohesion and adaptation and the anxiety and depression level of parents of children with congenital heart disease after surgery.Methods 302 parents of children with congenital heart disease and 330 parents in child health care clinic were conveniently selected and investigated with Hospital Anxiety and Depression Scale (HADS).And Family Cohesion and Adaptation Questionnaire (FACES Ⅱ-CV) was applied to investigate the former.Results The mean score of the anxiety and depression level of parents of children with congenital heart disease was higher than that of the parents in child health care clinic.The difference was significant.The score of anxiety and depression of parents of children with congenital heart disease was significantly correlated with dissatisfaction of family coherence and adaptation; while negatively correlated with real family cohesion and adaptation.Multiple linear regression showed that real family adaptation,dissatisfaction of family adaptation were influential important factors of parents' anxiety.Dissatisfaction of family adaptation was also the influential important factors of the parents' depression.Conclusions The anxiety and depression of parents was above the average level,we must pay more attention to improve it,make full use of the function of families,and to improve their anxiety and depression condition.

Objective To assess the reaching ability of hemiplegic stroke survivors using a motion capture unit (MCU) combined with surface electromyography (sEMG).Methods Sixteen stroke survivors with hemiplegia formed the experimental group,while healthy counterparts were selected as the control group.Both groups were asked to sit on a chair and reach for a cup on a table in front of their shoulder at arm's length using their affected arms in the experimental group and their right arms in the control group.MCUs were fixed on their spines and arms to obtain kinematic signals,and the sEMG signals of the trapezius,the anterior deltoids,biceps and triceps of the tested limb were recorded.Each subject repeated the test 3 times,and the best result was retained for further analysis.After signal processing,the range of movement of the shoulders and elbows was extracted along with the time used to reach the cup,peak angular velocity,time to peak velocity of the shoulders and elbows,work of the muscles and work ratios of the trapezius/deltoid and biceps/triceps.The upper limb section of the Fugl-Meyer assessment (FMA) was also administered to evaluate the patients' upper limb function.Independent sample rank sum tests compared the patients with the controls in terms of kinematics and sEMG parameters.Spearman analysis was used to explore the correlation between the FMA scores and the kinematics and sEMG characteristics.Results Significant differences in the kinematic and myoelectric indicators were found between the patients and the controls.The average FMA score of the patients was correlated with the peak velocity of the shoulder joint.Moreover,the ROM of the shoulder was closely related to the work of the trapezius,while the time for the shoulder joint to reach peak velocity was closely related to the work ratio of the biceps and triceps.Conclusion An MCU integrated with synchronous sEMG can quantitatively assess the kinematics and kinetics of hemiplegic stroke survivors,at least in reaching.This can provide objective guidance to optimize clinical rehabilitation.

The purpose of this study was to study the effect of three different transfection reagents (Lipofectamine™ LTX & PLUS™, Lipofectamine 2000 and Nano-PAMAM-D) and three different testicular injection methods (rete testicular injection, seminiferous tubules injection and testicular interstitial injection) on the efficiency of production transgenic mice. After the mixtures of plasmid DNA (pEFP-C1) and transfection reagent were injected with different testicular injection methods, the sperm density, vitality, positive sperm rates and PCR positive transgenic mice rate were examined 30 days after injection. The results showed that the damage degree from slight to serious of three transfection reagents was Lipofectamine™ LTX & PLUS™, Lipofectamine 2000, and PAMAM-D. The sperm positive rates with green fluorescence of these three groups were 35.65%±0.69%, 12.86%±0.35% and 10.04%±0.20%, respectively. The PCR positive rates of transgenic newborn mice were 29.17%, 13.70% and 5.88%, respectively. Among the groups of different testicular injection methods, the damage degree from slight to serious was rete testicular injection, seminiferous tubules injection, and testicular interstitial injection, whereas the sperm positive rates with green fluorescence were 35.13%, 15.13%, and 0%, respectively. The PCR positive rates of transgenic newborn mice among different testicular injection groups were 33.3%, 12.5%, and 0.0%. The combination of rete testicular injection and Lipofectamine™ LTX & PLUS™ had the lowest toxicity and highest transgenic efficiency in the production of transgenic mice.

Objective To evaluate the safety and feasibility of hepatectomy for huge focal nodu-lar hyperplasia of the liver. Methods The clinical data of 29 cases of huge FNH of the liver with an average diameter of 12.5 cm (10-26 cm) who were admitted to our hospital from 1996 to 2007 were retrospectively analyzed. Lesions protruded from the liver in 26 cases, compressed extrahepatic organs in 10 and adjoined or compressed hepatic hila in 19. Results All the lesions were successfully resected without operative death. The mean intraopreative blood loss was 747 ml (100-4000 ml). The first he-patic portal blocking was performed in 27 cases and the mean blocking time was 26 min (13-78 min).Among 19 cases of huge FNH involving hepatic hila, the mean intraopreative blood loss was 1011 ml,the mean blocking time 30 min and the liver cross-section was not completely sutured in 7 of these ca-ses. The intraoperative hemorrhea occurred in 7 and postoperative biliary fistula in 1. Twenty-seven cases were followed up for a median of 46 months (4-132 months) with no recurrence and the longest survival time had reached to 11 years. Conclusion Hepatectomy is a safe and feasible means for huge focal nodular hyperplasia of the liver. For those involving hepatic hila, distinguishing between the le-sion and intrahepatic vessels, performing resection closely around the lesion and dealing with the liver cross-section properly may be helpful to reduce the surgical complications.

Objective To prospectively investigate the association between serum uric acid concentration and the risk of brain infarction in Chinese adults.Methods In this prospective cohort study,a total of 95 738 participants (aged 18-98 years old) were included and were categorized into sex-specific quintiles according to serum uric acid concentration which were collected during 2006-2007 by health examinations.The study was followed up for an average of 4 years.We used Cox regression models to calculate hazard ratios (HR) and their 95％ confidence intervals (CI).Results (1) Higher concentrations of serum uric acid were associated with older age,obesity,higher blood pressure,higher serum concentrations of total cholesterol,triglycerides,and high sensitivity C-reactive protein,smoking,alcohol drinking,history of hypertension,hyperlipidemia and atrial fibrillation,and antihypertensive medication use.(2) The incidence of brain infarction for sex-specific quintiles were 0.84％ (33/3913),0.35％ (14/3985),0.44％(17/3888),0.54％ (21/3909),0.91％ (35/3860) in women (x2 =15.676,P =0.003) and 1.18％(180/15 238),1.26％ (191/15 170),1.11％ (170/15 323),1.45％ (221/15 216),1.82％ (277/15 236)in men (x2 =36.641,P =0.000).(3) After adjusting for potential confounders,including age,body mass index,blood pressure,fasting plasma glucose,total cholesterol,triglyceride,smoking,alcohol,and medical history of major chronic conditions and antihypertensive medication use,the HR (95％ CI) of brain infarction across serum uric acid quintiles were 2.06 (1.14-3.72),0.91 (0.45-1.84),1.00 (ref),1.11 (0.58-2.09),1.31(0.73-2.34) in women and 1.07 (0.86-1.34),1.02 (0.47-2.25),1.00 (ref),1.23(1.00-1.52),1.24(1.01-1.52) in men.Conclusions In this prospective cohort study,we find a U-shaped relationship between serum uric acid concentrations and brain infarction,a higher risk of developing brain infarction in association with low or high serum uric acid concentrations.Women with lowest or highest serum uric acid concentrations and men with higher serum uric acid concentrations are more likely to develop brain infarction.This probably because women have lower serum uric acid concentrations relative to men.Confirmation of our findings in larger cohorts with longer follow-up duration is warranted.
