Thirty eight adult male rabbits were selected for the experiment. The experimental peptic ulcer was induced by means of injection of 40% acetic acid to the submucosa of the stomach. Animals of the control group were injected with normal saline instead and another control group consisted of normal rabbits without any treatment. The animals were killed by decapitation at different time intervals (3～49 days) after the operation. The adrenal tissues were prepared for histochemical studies from both experimental and control animals. The results were observed as follows:During the early stage of the peptic ulcer, the fascicular and reticular zones were the chief sites in the adrenal cortex where histochemical changes were involved. Three days after the peptic ulcer operation, the cells of the fascicular and reticular zones filled with sudanophilic lipid droplets and cholesterol droplets. Five days after the operation, both of lipid droplets and cholesterol droplets decreased; the content of ascorbic acid increased slightly; and the activity of succinic dehydrogenase also increased. The above changes were most conspicuous in the inner portion of the fascicular zone within ten days. After fourteen days, all the above histochemical changes began to recover and gradually returned to the normal level after eighteen to thirty five days. In the normal saline operation control group, the contents of lipid droplets and cholesterol droplets decreased in the fascicular and reticular zones after three days and returned to normal level during the period of ten to fourteen days after operation for saline injection.The above histochemical changes showed that the adrenal cortex was at an active functional state during the early period of the experimental peptic ulcer.

Objective:To investigate the effects of Bailing capsules on the expression of TGF-β1 in the peritoneal dialysis solution for peritoneal dialysis patients. Methods: Totally 40 patients treated with peritoneal dialysis ( PD) were randomly divided into two groups (20 cases in the control group and 20 cases in the experimental group). All the patients were treated with PD by 1. 5% perito-neal dialysis effluent (6 000 ml everyday), and the patients in the experimental group were additionally treated with Bailing capsules (5 capsules each time, three times a day after meals) for 6 months. The adequacy of PD (including Kt/V and Ccr) of the two groups was examined after the one-month treatment. The renal function and the level of TGF-β1 in the effluent in 1, 3 and 6 month were com-pared between the two groups. Results:The adequacy of PD ( Kt/V and Ccr ) had no significant difference between the two groups (P<0. 05). The level of serum creatine was decreased significantly in both groups after the one-month treatment (P<0. 05), and no significant change was shown in 3 and 6 month (P>0. 05). In the control group, the expression of TGF-β1 in the effluent in 1, 3 and 6 month was increased gradually with significant difference (P<0. 05). In the experimental group, the expression of TGF-β1 in the effluent had no significant difference in 1, 3 and 6 month (P>0. 05), which was lower than that in the control group (P<0. 05). Conclusion:Bailing capsules can decrease the expression of TGF -β1 in the effluent for the patients treated with PD and inhibit the peritoneal fibrosis.

Objective: To investigate the relationship between serum leptin concentration and diet nutrition, age and gender. Method: One hundred fifty-eight men and women aged 18-72 y were initially drawn from a community in Jinan City. The parameters measured included height, weight and serum leptin concentrations. In addition, a 3-d food record was used to represent usual food intake by the participants. Results: The mean serum leptin concentration in males was 8.38?6.31ng/ml, while in females 24.98?13.29 ng/ml. Serum leptin level in males was significantly correlated with age, but not in females. Respectively, serum leptin level in males and females were not correlated to dietary factors. After adjusted for BMI, serun leptin level in females was positively correlated with dietary intake of fat, MUFA and PUFA. Conclusion: Serum leptin level in female is higher than that in male. Age is correlated to serum leptin level in males. The relation of dietary intake of fat, MUFA and PUFA to serum leptin concentration only existed in women.

Objective:To determinate the resistant starch in different kinds of food so as to provide the data for guiding the diet for health. Method:The contents of resistant starch in 6 kinds of food samples were determined by a method that mimicked gastrointestinal conditions. Results:The contents of resistant starch in raw food were higher than cooked food, except beans. The content of resistant starch of raw potato and deepfrying potato was respectively the highest, 46.06?2.65 g/100g total starch and 29.11?1.52 g/100g total starch. Conclusion:The repeatability of the analysis method was good, and the contents of resistant starch in various kinds of food were different.

Objective To investigate the nutritional risks, prevalence of undernutrition, and nutritional interventions among inpatients in departments of nephrology in some hospitals in Guangzhou, with an attempt to provide evidences for the nutritional support of patients with kidney diseases. Methods Totally 378 adult patients in departments of nephrology in Guangzhou were enrolled in this study by fix-point consecutive sampling. Nutritional Risk Screening 2002 (NRS 2002) was applied for nutritional risk assessment. Nutrition risk was defined by NRS score ≥3 and undernutrition by BMI ＜ 18.5 kg/m2 or serum albumin ＜ 30 g/L. Nutritional interventions were also evaluated in all patients. The relationship between nutritional risk and nutritional support was analyzed. Results The overall prevalence of undernutrition was 21.7% and the nutritional risk was 41.3%. They were especially high among patients with chronic kidney dysfunction (24. 3% and 60. 7% , respectively). The nutritional risk was 42. 3% in patients accompanied with diabetes (P＞0. 05). Of these 378 patients, 102 (27.0%) received nutritional interventions, in which the nutritional support rate was 50. 0% (78/156) for patients with nutritional risks and 10. 8% (24/222) for those without nutritional risks. Conclusions The nutritional risks and prevalence of undernutrition are high among inpatients in the departments of nephrology in hospitals in Guangzhou. Proper application of nutritional interventions remains a concern. Evidence-based guidelines are required to improve this situation.

Objective To evaluate the use of three-dimensional reconstruction (3D) to improve the success rate in the first attempt of radiofrequency ablation (RFA) for small hepatocellular carcinoma (HCC).Methods A retrospective study was conducted on 109 patients with small HCC (with single nodule from 3 to 5 cm in diameter) treated with radiofrequency ablation between June 2010 and June 2013.A safe ablation margin was evaluated before and after radiofrequency ablation.The patients were divided into two groups: the 3D-RFA group (49 patients were evaluated by three-dimensional reconstruction before RFA treatment) and the 2D-RFA group (60 patients were not evaluated by three-dimensional reconstruction before RFA treatment).The success rate of the first attempt of radiofrequency ablation, recurrence free survival, overall survival and complications were compared between the two groups.Results The success rate of first ablation reached 95.9％ (47/49) in the 3D-RFA group which was significantly higher than the 48.3％ (29/60) in the 2D-RFA group (P ＜ 0.05).The local tumor progression rate was 8.1％ in the 3D-RFA group versus 23.3％ in the 2D-RFA group (P ＜0.05).The 1-, 2-, 3-year recurrence free survival rates were 85.4％, 63.9％, and 49.8％ respectively in the 3D-RFA group and 72.4％, 43％, and 34.4％ respectively in the 2D-RFA group (P ＜ 0.05).The 1-, 2-, 3-year overall survival rates were 91.4％,78.4％, and 60.9％ respectively in the 3D-RFA group and 83.3％, 58.7％, and 40.9％ respectively in the 2D-RFA group (P ＜0.05).Complications occurred significantly less in the 3D-RFA group (4％, 2/49) than the 2D-RFA group (13.3％, 8/60;P ＜ 0.05).Conclusion Three-dimensional reconstruction improved the success rate of the first attempt of radiofrequency ablation and the prognosis of patients, and with less complications for small hepatocellular carcinoma.

Objective To explored high-risk HPV genotyping PCR testing whether as a feasible means for the early screening of cervical cancer and precancerous lesions. Methods From January 2013 to June 2014, 15 192 outpatients in China-Japan Friendship Hospital voluntary were tested by high-risk type HPV genotyping PCR. The average age of them were (33±8) years old. High-risk HPV types genotyping PCR tested by fluorescence PCR technology,in which 13 kinds of high-risk HPV subtypes were detected,
including HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 and 68. A total of 4 315 cases of them were tested by the liquid-based cytology (LCT), among them with positive of high-risk HPV genotyping tested by PCR (n=2 366) were biopsy under colposcope (648 cases) in those LCT results were positive or LCT negative but HPV16 positive or LCT negative but had the clear clinical symptoms or and non-HPV16 positive but with clear clinical symptoms. (1) Analysis high-risk HPV infection status of 15 192 women.(2)As the pathological diagnosis was the gold standard in the diagnosis of cervical lesions, analysis of the relationship among high-risk HPV infection,virus loads and cervical lesions. (3) To evaluated the value of high-risk HPV genotyping PCR tested method in screening of cervical cancer and precancerous lesions. Results ⑴ Of 15 192 cases tested by high-risk HPV genotyping PCR, 2 366 cases were HPV positive (HPV infection), the overall infection rate was 15.57%(2 366/15 192), in which a single subtype of HPV infection in 1 767 cases, infection rate was 11.63%(1 767/15 192), and multiple subtypes of HPV infection (two and more subtypes HPV infection) in 599 cases, infection rate was 3.94%(599/15 192). The HPV16, 52 and 58 infections were the most common HPV subtypes in 13 subtypes, the infection rate was 3.95% (600/15 192), 2.86%(435/15 192) and 2.67% (406/15 192), respectively. (2) The most relevant subtypes with cervical intraepithelial neoplasia (CIN)Ⅱand even higher lesion were HPV16, 52 and 58, accounted for 57.7%(154/267) of all above CINⅡlesions. The most relevant subtype with the cervical glandular intraepithelial neoplasia (CGIN) Ⅱ or above lesions was HPV18, 3 cases with CGIN Ⅱ or above lesions were all single HPV18 infection. The pathologic examination positive percentage of patients which HPV virus loads≤103 copys/104 cells was 18.2%(25/137), while the pathologic examination positive proportion was 33.3%(247/742) which HPV virus loads≥104 copys/104 cells , there was statistically significant difference between them (χ2=27.06, P=0.000).(3)Sensitivity, specificity, positive predictive value and negative predictive value for detection of CINⅡ or above using HPV genotyping PCR were 96.11%, 85.76%, 30.94% and 99.70%, respectively. Conclusions There were a guiding significance for high-risk HPV genotyping PCR tested in screening of cervical cancer and precancerous lesion. HPV16, 52 and 58 were related to the severe cervical squamous epithelial lesions, while HPV18 was related to cervical severe glandular cell pathological changes. HPV genotyping is feasible and economical as the first choice of opportunistic screening in tertiary hospitals.
