Most anticancer drugs inhibit tumor cell growth by inducing apoptosis.Apoptosis-evasion,also enhancement of anti-apoptosis ability(e.g.anti-apoptosis related genes over-expression or pro-apoptotic related genes loss,etc.)may lead to tumor cell multidrug resistance.Many researches show that apoptosis-evasion is one of the important factors resulting in tumor multidrug resistance.

Vascular dementia is one of the common causes of cognitive impairment.Occlusion of bilateral common carotid arteries, middle cerebral artery occlusion, as well as induced hypertension are major methods to make rat model for vascular dementia.The present review will summarize research progress in medical and non-medical treatment of vascular dementia rat models in order to provide theoretical direction for clinical practice.

AIM:To study the method of determing camphor, menthol, synthetic bornel and the wintergreen oil contents in Shexiang Zhunggu Plaster. METHODS: Gas phase chromatogram was used to determine contents of camphor, menthol, synthetic bornel and the wintergreen oil in Shexiang Zhuanggu Plaster. The chromatogram condition consisted of the capillary vessel column(PEG-20M, 30 m?0.32 mm?0.25 ?m). The temperature programing rose from 100 ?C to 130 ?C by 5 ?C /minute, then 30 ?C /minute to 200 ?C , lasting 2 minutes in the end. The temperature of the entrance of the capillary vessel column: at 220 ?C , temperature of the detector was 240 ?C ; N_2: 5 mL/minute, H_2: 45 mL/minute, Air: 450 mL/minute; sample quantity was 0.2 ?L. RESULTS: Under certain chromatogram condition, there was linear relation among the camphor, menthol, synthetic bornel and the wintergreen oil and the peak area in the scope of 0.027 38 mg/mL-0.438 08 mg/mL, 0.041 15 mg/mL-0.658 4 mg/mL, 0.033 38 mg/mL-0.534 1 mg/mL, 0.042 15 mg/mL-0.674 4 mg/mL, respectively. The average recoveries were 98.37%, 99.76%, 98.80% and 97.61%, respectively. RSD were 1.7%, 1.8%, 0.96% and 1.5%, respectively. CONCLUSION: This experiment provides an accurate and reliable method to control the quality of Shexiang Zhuanggu Plaster.

Objective To explore the effects of early postnatal nutrition on adult-onset insulin resistance by an artificial nutrition intervention during the critical period. Methods On postnatal day 2, Sprague-Dawley rats were assigned randomly to overnutrition (SL), normonutrition (NL) and undernutrition (LL) via artificially adjusting the number of pups nursed per dam. Litter size was adjusted to 3 pups/dam, 10 pups/dam and 20 pups/dam for the SL, NL and LL groups, respectively. There were eight litters for each group. All the pups were nursed by their natural dams and fed with a standard rodent laboratory chow. The pups were weaned on postnatal day 21 and three male pups from each litter were separated. After that, all male rats were housed three per cage and fed standard chow until 16 weeks old. At 3 and 16 weeks, rats were killed after overnight fasting and blood was collected. Liver, gastrocnemius muscle and perirenal and epididymal fat pads were dissected and weighed to calculate relative mass after normalization for body weight. Physiological parameters, biochemical values and insulin resistance status, including serum insulin level, homeostasis model assessment for insulin resistance (HOMA-IR) index and intraperitoneal glucose tolerance test (IPGTT), were dynamically monitored. Analysis of variance was used for statistical analysis. Results (1) Before weaning, the body weights of SL rats were significantly heavier than NL rats after postnatal day 10, and weights of LL rats were significantly lower than NL rats after postnatal day 7. After weaning, body weights of SL rats still remained heavier and weights of LL rats continued to be lower than NL rats (P<0.05). (2) At 3 weeks, the weights of liver and perirenal and epididymal fat pads in SL rats were significantly heavier than NL rats, whereas LL rats were lower than NL rats (P<0.05). At 16 weeks, the weights of liver, epididymal fat pads and gastrocnemius muscle in SL rats were significantly heavier than NL rats. Meanwhile, the weights of all detected tissues in LL rats were lower than the NL group. The weights of epididymal fat pads after normalization for body weight in the SL group were heavier than the NL group (P<0.05). (3) At 3 weeks, the fasting serum glucose level of the SL group was significantly higher than the NL and LL groups [(7.77±1.10) vs (6.33±1.20) and (5.80±1.51) mmol/L, respectively, F=13.217, P<0.01]. At 16 weeks of age, the serum insulin level in SL rats significantly increased compared to NL and LL rats [(0.31±0.11) vs (0.16±0.08) and (0.14±0.11) ng/ml, respectively, F=5.369, P=0.017]. For HOMA-IR evaluation, the index was significantly lower in LL rats compared to NL and LL rats at 3 weeks of age [(0.09±0.01) vs (0.25±0.01) and (0.31±0.05), respectively, F=25.923, P=0.005]. At 16 weeks, the index was significantly elevated in SL rats compared to NL and LL rats [(1.77±0.53) vs (0.84±0.44) and (0.83±0.67), respectively, F=5.765, P=0.015]. Furthermore, IPGTT was performed in all groups at 14 weeks of age. SL rats had significantly higher serum glucose levels at 60 min and a significantly increased area under the curve when compared to NL and LL rats (all P<0.05). (4) Serum from 16 week old SL rats was found to contain significantly higher levels of albumin, triglycerides and free fatty acids compared to NL rats (all P<0.05). Conclusions Early postnatal overnutrition induces persistent overweight and visceral white adipose accumulation in rats, while early postnatal undernutrition show the opposite effects. Early postnatal overnutrition may lead to adult-onset insulin resistance in rats. Avoiding overnutrition during the early postnatal period, a critical window for growth and development, may prevent or decrease later metabolic risks.

Andrology and gynecology have a similar or the same theoretical basis in Traditional Chinese Medicine (TCM). Andrology has a history of less than 3 decades in China, while TCM gynecology has developed for over a thousand years. The development of andrology could be greatly promoted with the guidance of the theories and prescriptions of gynecology.

Objective To estimate the frequency of heart valvular involvement in Chinese patients with Takayasu arteritis (TAK) and its correlation with other clinical features. Methods Ninety-one patients with TAK were studied and their clinical manifestations, laboratory test, vascular images and echocardio - gra-phic findings were retrospectively reviewed. The data were compared between patients who had heart valvular involvement and those who had not. Mann-Whitney U-test or Student's t-test, Chi-squared test or Fisher's exact test were used for analysis. Results Aortic regurgitation and mitral regurgitation were both confirmed in 20 (22%) patients. Tricuspid regurgitation and pulmonary valve regurgitation were observed in 10 (11%) and 2 (2%) patients, respectively. Older age at onset, longer disease duration, hypertension and involvement of the ascending aorta were all significantly more frequent in TAK patients with aortic regurgitation (t=2.903, P<0.01; Z=-2.759, P<0.01; χ2=7.918, P<0.01; Z=-4.454, P<0.01) than those without. However, the constitutional symptoms and acute phase reactants [erythrocyte sedimentation rate (ESR) and C reactive protein (CRP)] were not statistically different between patients with and without valvular regurgitation (P>0.05). Aortic valvular pathology examination of the three TAK patients who had underwent aortic valve replacement showed no inflammatory cell infiltration. Conclusion This study has demonstrated that heart valve involvement is common in patients with TAK, mainly in the form of regurgitation, and which may be secondary to hypertension and other cardiovascular complications. We should pay more attention to the screening and treatment of heart valvular involvement in TAK patients.
