OBJECTIVETo evaluate the therapeutic effect of Liujunzi decoction combined with Zuojin pills in treating the radioactive duodenitis and their mechanism, and compare with clinical routine acid suppressants combined with mucous membrane protective preparations to study the mechanism of their efficacy.

METHODAccording to the study of Williams J P and characteristics of duodenitis, and by reference to the radiation enteritis modeling standard, we took the lead in establishing the mouse radioactive duodenal injury model. The model mice were randomly divided into the control group (n = 26), traditional Chinese medicine (TCM) group (n = 16) and the western medicine (oral administration with famotidine 0.5 mL + almagate suspension 0.3 mL per mouse, once a day) group (n = 16). After the standard administrating, such objective indexes as general condition, weight, changes in health score, pathology and expression of inflammatory factors were observed to evaluate the efficacy.

RESULTThe radioactive duodenitis model of mice was successfully established with 12 Gy. Mice in the control group suffered from weight loss, anorexia, low fluid intake, loose stools, and occasionally mucous bloody stool, poor spirit, dim fur, lack of exercise and arch back. Mice in drug intervention groups were generally better than those in the pure irradiation group. The IL-6, IL-1beta, TNF-alpha mRNA expressions in spleen and mesenteric lymph node tissues in TCM and western medicine groups showed a declining trend compared with the control group. Their concentrations in peripheral blood serum also slightly changed. The TCM group revealed notable advantage in reducing inflammatory factors. The microscopic observation showed that a better mucosa repair in intervention groups than the pure irradiation group. The improved Chiu's scoring method showed a statistical significance in the difference between TCM and western medicine groups (P < 0.05).

CONCLUSIONLiujunzi decoction combined with Zuojin pills could treat acute radiation enteritis, regulate organic immunity, and inhibit acute injury, promote local tissue repair, with the potential to resist such adverse effects as radiation intestinal fibrosis. The regulation of inflammatory factor release is one of efficacy generation mechanisms.

Hypospadias is one of the most common congenital malformations, and its main clinical manifestation is the abnormal opening of the urethra. Etiologically, it can be attributed to many factors, mainly including genetic, hormonal, and environmental factors. Recently studies about its genetic etiologies have found a variety of hypospadias-associated genes from the aspects of epidemiology and polymorphism, mainly those involving the formation of the penis, the development of the testis, the anabolism of androgens, and so on. This review focuses on the progress in the studies on the genetic etiology of hypospadias.

Objective To assess the treatment effects of As_2O_3-PLGA microspheres on VX2 rabbits liver tumor models.Methods Thirty-two New Zealand white rabbits were involved with formation of VX2 rabbits liver tumor models,and randomly divided into 4 groups of 8 each.(a)As_2O_3 plus 0.9% NaCl solution group:3 F co-catheter was plugged into hepatic artery,and then As_2O_3(3 mg/kg)plus 10 ml 0.9%NaCl solution was injected into the tumor through the feeding artery;(b)As_2O_3-PLGA microspheres group :As_2O_3- PLGA microspheres(3 mg/kg)was injected into the tumor through the feeding artery;(c)PLGA mierospheres group:Injection of PLGA microspheres(3 mg/kg)injected into the tumor through the feeding artery;(d) control group:0.9% NaCl solution(10 ml)was injected into the feeding artery.Dual phase helical CT scans were performed the day before treatment,20 days after treatment and finally the rabbits were sacrificed.The sizes of the tumor were measured and followed by histopathological analysis and HE staining.Results The volumes of tumors post operatively of group a,b,c and d were(31.08?11.15)cm~3,(3.82?2.537)cm~3, (13.22?4.665)cm~3 and(115.8?62.01)cm~3 respectively.The most significant treatment effect was available in group b,with more coagulation necrosis and fibrotic tissue formation.Statistical analysis indicated that the treatment effects of group a,b,c were better than that of group d with significant difference which can be also seen between group a and b,group b and c.Conclusion As_2O_3-PLGA microspheres shows rather excellent chemoembolization effects on VX2 rabbit liver tumor model with safely.

OBJECTIVETo investigate the role of endoplasmic reticulum stress in the apoptosis of testicular germ cells in hyperlipidemic rats.

METHODSWe randomly assigned 42 four-week-old male Wistar rats into a normal control group (n = 12) and a high-fat group (n = 30) to be fed on a normal diet and a high-fat diet, respectively, for 10 weeks. Then we measured the concentrations of triglyceride (TG) and total cholesterol (TC) in the serum using an automatic biochemistry analyzer, detected the apoptosis of testicular germ cells by TUNEL staining, and determined the protein and mRNA expressions of GRP78 and. caspase-12 in the testis tissue by immunohistochemistry and RT-PCR, respectively.

RESULTSThe concentrations of TG and TC were significantly increased in the animals of the high-fat group ([3.00 ± 0.92] and [3.04 ± 0.39] mmol/L) as compared with the control rats ([1.43 ± 0.41] and [1.55 ± 0.23] mmol/L) (P < 0.01), and so was the apoptosis index of the testicular germ cells ([37.17 ± 2.74]% vs [5.16 ± 0.81]%, P < 0.01). The high-fat group, in comparison with the control, also showed remarkably upregulated protein and mRNA expressions of GRP78 (0.32 ± 0.03 and 0.86 ± 0.05 vs 0.19 ± 0.01 and 0.37 ± 0.03, P < 0.01) and caspase-12 (0.34 ± 0.02 and 0.87 ± 0.01 vs 0.12 ± 0.01 and 0.34 ± 0.03, P < 0.01) in the testis tissue.

CONCLUSIONThe apoptosis of testicular germ cells is increased in hyperlipidemic rats, which may be attributed to endoplasmic reticulum stress.

Objective To observe the efficacy of a medical disinfectant ultrasonic coupling agent on the killing of five clinically isolated multidrug-resistant organisms(MDROs).Methods From March 2016 to May 2017,a disin-fection ultrasonic coupling agent containing active ingredient,including triclosan and propylene glycol,was used to conduct carrier quantitative germicidal test on five clinically isolated MDROs,the killing efficacy to MDROs was ob-served.Results After 1.5,3.0,and 4.5 minute disinfection time,the killing logarithms values of disinfection ultra-sonic coupling agent to five MDROs(multidrug-resistant Acinetobacter bau m annii[MDR-AB],methicillin-resistant Staphylococcus aureus[MRSA],multidrug-resistant Pseudomonas aeruginosa[MDR-PA],carbapenem-resistant Klebsiella pneumoniae[CRKP],and extended-spectrum β-lactamase Escherichia coli[ESBLs-EC])were all>3.0. Conclusion Medical disinfection ultrasonic coupling agent can effectively kill five common MDROs,and can take the place of disinfectant during ultrasonic examination.

Objective To investigate surgical opportunity and suitable treatment approach in nodular Hashimoto's disease.Methods An analysis was performed in 388 pathologically confirmed cases with nodular Hashimoto's disease and other thyroid-related diseases.All the cases were involved with surgical treatment due to thyroid nodules from June,1995 to Dec,2005.Results Among the above-mentioned cases,64 cases (16.5%) were Hashimoto's disease with the presence of thyroid cancer,190 (48.9%) nodular thyroid tumor,94 (24.2%) thyroid adenoma,7 (1.8%) hyperthyroidism,the rest (8.5%) simple Hashimoto's disease.Prior to 2000, among 106 cases of Hashimoto's disease there were 15 cases accompanied by thyroid cancer.Since 2001,282 cases of Hashimoto's disease were dealt surgically,49 of which had thyroid cancer.Compared to the period from 1995 to 2000,the complication of Hashimoto's disease and thyroid cancer has been sharply increasing during the recent five years (P

Objective To study the effects of granisetron hydrochloride on vasovagal syncope(VVS) in rabbits.Methods Twenty-four healthy New Zealand rabbits were divided stochastically into control group and intervention group,12 in each group. The control group was injected intravenously with normal saline. The intervention group was injected intravenously with granisetron hydrchloiride.Rabbit VVS models were established,each was taken at 4 points in time in the bloodletting process:T1,T2,T3,T4,to compare the bloodletting time,the concentration of 5-hydroxytryptamine(5-HT) in T2,T3,T4 and the total blood volume between the groups,and monitor the heart rate, blood pressure during the entire process.Results 1.The time of intervention group in T2,T3,T4 was longer than the time of control group obviously(P
