OBJECTIVE: To investigate the therapeutic effect of treatment based on syndrome differentiation and its influence on the serum levels of testosterone and insulin in women with polycystic ovary syndrome (PCOS). METHODS: Forty-three women, diagnosed with PCOS as well as syndrome of kidney yin deficiency or syndrome of spleen qi deficiency, were enrolled in the study. Twenty-five PCOS women with syndrome of kidney yin deficiency were treated with traditional Chinese herbs for nourishing yin to reduce fire (nourishing yin group), and 18 PCOS women with syndrome of spleen qi deficiency were treated with herbs for invigorating spleen and replenishing qi (replenishing qi group). Body mass index (BMI), waist-to-hip ratio (WHR), waist circumference (WC), and the serum levels of insulin and testosterone before and after treatment were detected. RESULTS: Among the 43 cases, 20 cases had high serum testosterone level, in which 13 cases with syndrome of kidney yin deficiency, 7 cases with syndrome of spleen qi deficiency, but the difference had no statistic significance; 17 cases had high serum insulin level, in which 11 cases with syndrome of spleen qi deficiency, 6 cases with syndrome of kidney yin deficiency, the difference had statistic significance (P<0.05). In nourishing yin group, the serum levels of insulin and testosterone declined after treatment (P<0.05), and BMI, WHR and WC showed no significant changes. In replenishing qi group, the serum level of insulin declined after treatment (P<0.01), and BMI, WHR, WC and the serum level of testosterone showed no significant changes. CONCLUSION: Traditional Chinese herbs for nourishing yin to reduce fire can significantly reduce the serum levels of testosterone and insulin in PCOS women with syndrome of kidney yin deficiency, and herbs for invigorating spleen and replenishing qi can significantly reduce the serum level of insulin in PCOS women with syndrome of spleen qi deficiency.

Polycystic ovary syndrome (PCOS) is an endocrine disorder with a variety of etiopathogensis and clinic manifestations. Hitherto its pathogenesy is still uncleared. However, there have been increasing supports for the contribution of the hyperinsulinism and hyperandrogenaemia in the pathological process of the PCOS. Recent years, some literatures reported that hyperleptinaemia is also an important factor. This review seeks to bring together the pothogenesy of the PCOS with these factors.

Objective To evaluate the impacts of comprehensive diabetes intervention to provide evidence for effective diabetic control in rural communities.Methods Diabetic patients from four communities at Wujin District of Changzhou City were selected.One hundred and seventy-three patients from two communities received comprehensive intervention,including medication therapy,diabetes education,and diet.exercise,and behavior instruction(intervention group);142 patients from the other two communities got medication therapy only (control group).All the participants were interviewed with structured questionnaire and phyrsical examination.The second epidemic investigation was conducted at 4 years to evaluate the effects of the intervention.Results At the end of the intervention,the awareness rates of normal fasting plasma glucose,major diabetes risk factors,healthy diet,and therapeutic strategies in the intervention group were 90.8%.74.6%,89.6%,and 59.5%,respectively,which were significantly higher than those in the control group (all P<0.05).For the intervention group,the rates of diet behavior or physical exercise change were 68.8% and 58.4%.respectively.which were much higher than those of the control group(all P<0.05).The average levels of systolic pressure,diastolic pressure,fasting plasma glucose,and total cholesterol were (130.6±10.4)mm Hg(1 mm Hg=0.133 kPa),(78.4±7.5)mm Hg,(6.2±3.1)mmol/L,and (4.5±0.9)mmol/L,respectively,in the intervention group,which were lower than those in the control group(all P<0.05).Conclusion Comprehensive intervention shows significant effects on rural community patients with diabetes.

AIM: To observe the neuroprotective effect of combined treatment with taurine and diazepam against focal cerebral ischemia-reperfusion in rats. METHODS: Sixty male Sprague-Dawley rats were randomly divided into five groups: sham-operation group, vehicle group, taurine group (200 mg/kg, ip), diazepam group (10 mg/kg, ip) and combined treatment group (taurine 100 mg/kg+diazepam 5 mg/kg). Focal cerebral ischemia was induced by the method of middle cerebral artery occlusion (MCAO) in rats, and reperfusion was emerged by removing the thread 2 h later. The drugs were administered respectively at the time of reperfusion, and subsequently repeated once 12 h later. The animals in vehicle group were intraperitoneally injected with isodose normal saline. The neurological deficit score, the brain water content and cerebral infarction were measured 48 h after MCAO. Other 5 group animals of focal cerebral ischemia-reperfusion (n=16 in each group) were set up as mentioned above and accepted treatments 10 h after reperfusion, likewise repeated once 12 h later. Twelve animals in each group were adopted the same management as the previous 5 groups at 48 h after MCAO. The remained 4 animals in each group were sacrificed until two weeks after MCAO to observe the histopathological changes by nissl staining. RESULTS: Compared to vehicle group, the animals in combined treatment group at 2 h or 12 h after MCAO both decreased the neurological deficit score, reduced the brain water content and infarct volume (P<0.01 or P<0.05). The combined treatment significantly alleviated the neurological necrosis as well. The neuroprotective effect of the combined treatment was superior to that of using taurine or diazepam alone. CONCLUSION: These results suggest that combination of taurine and diazepam treatment has a coordinate neuroprotective effect on both the acute and chronic brain damage of focal cerebral ischemia-reperfusion.

Methods With randomized cluster sampling,investigations including questionnaires,physical examination,fasting plasma glucose,blood lipids were performed in rural population aged over 60 years in Changzhou city in 2004-2005. Results A total of 4976 elderly people were enrolled in the study.The prevalence of MS was 24.1%,and 10.3%in men,34.3%in women by international diabetes federation(IDF)2005 definition.86.2%individuals had one or more of the metabolic disorders.Logistic regression analysis showed that sex,smoking,sweetmeat,family history of essential hypertension(EH)and tea drinking were influencing factors of MS. Conclusions The prevalence of MS is high in rural elderly population,especially in females.

The incidence of menopausal anxiety and depression is increasing. It can induce and aggravate a variety of somatic symptoms. Despite of the good effects of psychotropic drugs on the disease, patients' compliance is poor. Therefore, it is necessary to find a drug which is practical, effective, and easy for patients to take.

Objective To discuss the correlation between molecular subtypes of early stage breast cancer patients with positive sentinel lymph nodes and the metastasis of non-sentinel lymph nodes, and find out the factors predicting the metastasis of non-sentinel lymph nodes. Methods The clinical data of 124 female breast cancer patients with sentinel lymph node positive were retrospectively analyzed, and the patients were treated with axillary lymph node dissection. And the correlations were analyzed by single factor analysis and multiple factor Logistic regression analysis. Results Among the 124 patients,non-sentinel lymph node metastasis was in 45 cases (36.3%), and only sentinel lymph node positive was in 79 cases (63.7%). The single factor analysis result showed that the age≤35 years, number of sentinel lymph node positive≥2, macrometastasis of sentinel lymph node had correlation with the metastasis of non-sentinel lymph node (P<0.05 or<0.01);but the molecular type, operation method, maximum tumor diameter had no correlation with the metastasis of non-sentinel lymph node (P>0.05). The multiple factor Logistic regression analysis result showed that the number of sentinel lymph node positive and circumstance of sentinel lymph node positive lesions were the independent risk factors of the non-sentinel lymph node metastasis in patients with sentinel lymph node positive (OR = 4.589 and 2.948; P<0.01 or <0.05). Conclusions The circumstance of sentinel lymph node positive lesions and number of sentinel lymph node positive are the independent risk factors of the non-sentinel lymph node metastasis, but the molecular type is not correlated with the metastasis of non-sentinel lymph node. Predicting non-sentinel lymph node metastasis should be combined with clinical and pathological factors.

Objective: To explore the effect of introducing multi-dimensional care strategy based on the concept of cognitive goal implementation in patients with femoral head necrosis replacement. Methods: From April 2016 to July 2018, 94 patients with femoral head necrosis were treated in Hainan Third People's Hospital. According to the digital table, the clinical subjects were named as study group and control group, 47 cases each. Among them, the control group carried out traditional intervention, while the research group carried out multi-dimensional care strategy based on the concept of cognitive goal implementation. The self-management ability, quality of life and satisfaction of the two groups were compared before and 4 weeks after the intervention. Results: After intervention, the scores of life behavior, rest and sleep, exercise, diet, medication compliance, self-monitoring, psychological counseling and regular reexamination in the study group were (2.0 ± 0.6), (1.9 ± 0.5), (1.8 ± 0.3), (2.0 ± 0.5), (2.4± 0.7), (2.0 ± 0.5), (2.1 ± 0.7) and (2.1 ± 0.6) respectively, which were higher than those in the control group (1.6 ± 0.4). There were significant differences in scores (t = 10.268-20.369, P<0.05). The scores of physiological function, physiological function, social function, mental health, emotional function, vitality, somatic pain and general health in the study group after intervention were (80.6 ± 6.5), (43.7 ± 4.2), (75.1 ± 6.1), (69.5 ± 5.1), (50.9 ±4.4), (66.5 ± 5.0), (79.3 ± 5.2) and (65.9 ± 6.0) respectively, which were higher than those in the control group (67.3 ± 4.2).) There were significant differences in scores (t = 11.803-18.277, P<0.05). The good rate of target implementation in the study group was 89.4% (42/47), which was higher than that in the control group (65.9% (31/47). The difference was statistically significant (χ² = 16.782, P<0.05). The nursing satisfaction of the study group was 97.9% (45/47), higher than that of the control group 85.1% (40/47). The difference was statistically significant (χ²=4.919, P<0.05). Conclusion Multidimensional care strategy based on the concept of cognitive goal execution can improve self-care ability and quality of life of patients with femoral head necrosis replacement, and improve patient satisfaction.

Objective:To investigate the in vitro anti-cancer effect of Vinorelbine (NVB) combined with adriamycin (PLD) on human breast cancer MCF-7 cells and related mechanisms.Methods:The effects of NVB and PLD alone or in combination on the proliferation of breast cancer cells were detected by CCK-8 experiment. Flow cytometry was used to detect cell apoptosis and changes in reactive oxygen species (ROS) levels. Western blot experiment was carried out to detect protein expression.Results:The results of CCK-8 showed that compared with the blank control group, the inhibition rates of the vinorelbine treatment group, the adriamycin treatment group and the combined treatment group were 27.6%, 31.2% and 65.4%, compared with the NVB group and PLD group, the difference between the combined treatment group was statistically significant ( P=0.005 vs 0.001) . The results of flow cytometry showed that the proportion of apoptotic cells in each group was 3.54%, 16.95%, 15.01% and 32.24%, compared with the NVB group and PLD group, the difference between the combined treatment group was statistically significant ( P=0.006 vs 0.005) . The levels of reactive oxygen species in each group were 1, 1.03, 1.06 and 1.57, compared with the NVB group and PLD group, the difference between the combined treatment group was statistically significant ( P=0.008 vs 0.007) . Western blot results showed that the expression of p-ERK and p-STAT3 decreased after the combination of NVB and PLD, which inhibited the ERK/STAT3 signaling pathway. Conclusions:The combination of NVB and PLD can promote the apoptosis of breast cancer cells and inhibit the proliferation of breast cancer cells with high efficiency and low toxicity. Its mechanism of action may be related to the up-regulation of ROS levels in cells, thereby inhibiting the activation of the ERK/STAT3 pathway.
