OBJECTIVE To investigate the incidence of integrons in Pseudomonas aeruginosa strains isolated from blood samples in Peking University People′s Hospital and to analyze the correlation between integrons and drug resistance of P.aeruginosa.METHODS Forty-two strains of clinically isolated P.aeruginosa were collected.The antibiotics susceptibility was tested by K-B methods.Integrase gene of integron was amplified by PCR using degenerate primers.The integrons were classified by restriction fragment length polymorphism(RFLP) analysis of positive PCR products with Hinf Ⅰ restriction enzyme.RESULTS The drug-resistance rates of 42 strains of P.aeruginosa against 20 kinds of antibiotics ranged from 9.5% to 100%.Twenty-three strains were resistant to 12 kinds of antibiotics.Nineteen of the 42 isolates(45.2%) contained integrons,all of which were revealed as class Ⅰ of integrons by RFLP analysis.Neither class Ⅱ nor class Ⅲ of integron was detected.The positive percentage of integrons was increased by years.CONCLUSIONS Class Ⅰ integrons are widespread in isolates from blood samples in our hospital.The presence of integrons is closely associated with multi-drug resistance of P.aeruginosa.

OBJECTIVETo observe the effect of Zhenqing Recipe (ZQR) on non-alcoholic fatty liver (NAFL), and the expression of hepatic salt-inducible kinase 1 (SIK1) and sterol-regulatory element binding protein-ic (SREBP-lc) in type 2 diabetes rats.

METHODSA rat model of type 2 diabetes was established by high fat/sucrose diet combined with intraperitoneal injection of small dose streptozotocin (STZ) . Modeled rats were randomly divided into the model group, the ZQR group, and the metformin group, 8 in each group. Eight rats were recruited as a normal control group. ZQR at the daily dose of 12 g crude drugs/kg was administered to rats in the ZQR group by gastrogavage. Metformin suspension at the daily dose of 150 mg/kg was administered to rats in the metformin group by gastrogavage. Equal volume of distilled water was administered to rats in the normal control group and the model group. All medication lasted for 12 weeks. The levels of fasting blood glucose (FBG), free fatty acid (FFA), serum triglyceride (TG), serum total cholesterol (TC), serum alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected. The body weight and wet liver weight were weighed, and the liver weight index calculated. The liver TG content was measured. The pathological changes of liver and the expression of SIK1 were observed by HE staining and immunohistochemistry. The mRNA and protein expression of SIK1 and SREBP-1c were detected using RT-PCR and Western blot.

RESULTSCompared with the normal control group, FBG, FFA, TG, TC, ALT, AST, liver weight index, and liver TG contents significantly increased (P < 0.01); liver steatosis was severe, the mRNA and protein expression of SIK1 obviously decreased (P < 0.01); mRNA and protein expression of SREBP-1c increased (P < 0.01). After drug therapy, compared with the model group, FBG, FFA, TG, TC, ALT, AST, and liver weight index significantly decreased, liver TG contents significantly decreased, the mRNA and protein expression of SIK1 obviously increased, while mRNA and protein expression of SREBP-1c obviously decreased (P < 0.05, P < 0.01) in the ZQR group and the metformin group (P < 0.05, P < 0.01); and the pathological changes were also improved. All the indices were improved more in the ZQR group (all P < 0.05).

CONCLUSIONIn this experiment, we found that the expression of SIK1 decreased in NAFL rats with type 2 diabetes. ZQR could alleviate lesion of NAFL type 2 diabetes rats possibly by up-regulating hepatic SIK1 expression at mRNA and protein levels.

Background:Tryptophan(TRP)is an essential amino acid,and can produce 5-hydroxytryptamine(5-HT)via 5-HT signal pathway and kynurenine( KYN)metabolic pathway under the catalysis of enzyme,thereby participating in the pathogenesis of visceral hypersensitivity in diarrhea-predominant irritable bowel syndrome(IBS-D). Aims:To investigate the relationship between visceral sensitivity and TRP metabolic pathway in patients with IBS-D. Methods:Thirty patients with IBS-D and 30 healthy controls from June 2012 to January 2014 at Guangdong Provincial TCM Hospital were enrolled. Score of gastrointestinal symptom rating scale( GSRS)was evaluated. Visceral sensitivity was measured by anorectal manometry. RT-PCR and Western blotting were used to detect mRNA and protein expressions of colon mucosal IDo, respectively. Serum 5-HT,5-HIAA,TRP,IDo,KYN,KYNA concentrations and IDo activity,KAT activity were determined by high performance liquid chromatography assay. Results:Compared with control group,GSRS score was significantly increased(P < 0. 05),initial perception threshold,defecation threshold,pain threshold were significantly decreased(P < 0. 05),anorectal constriction pressure was significantly increased( P < 0. 05),serum 5-HT,5-HIAA concentrations were significantly increased(P < 0. 05),mRNA and protein expressions of IDo were significantly increased (P < 0. 05),serum KYN was significantly increased(P < 0. 05),KYNA was significantly decreased(P < 0. 01),IDo activity was significantly incseased(P < 0. 01),and KAT activity was significantly decreased in IBS-D group(P < 0. 01). Correlation analysis showed that initial perception threshold,defecation threshold,pain threshold and anorectal constriction pressure were correlated with 5-HT,5-HIAA,TRP,KYN,KYNA,IDo activity and KAT activity in patients with IBS-D (P < 0. 05). Conclusions:TRP metabolic pathway is correlated with visceral hypersensitivity in patients with IBS-D.

In order to study the analgesic effect of Shaoyao Gancao Decoction, this paper discussed material basis and mechanism from the perspective of macromolecules in traditional Chinese medicine. Inspired by the phenomenon of turbidity after boiling Chinese medicine, this experiment took Shaoyao Gancao Decoction as the research object to study the formation process of precipitation during boiling. The results showed that aggregates with a certain shape were formed in the solvent during the boiling process, and the precipitate was obtained by standing and centrifuging. Analysis found that the precipitation was mainly composed of small molecules such as paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid, isoliquiritin and gallic acid, and macromolecules such as protein and polysaccharide. The composition of precipitate was consistent with that of Shaoyao Gancao Decoction, but the analgesic effect of Shaoyao Gancao Decoction after removing the precipitate was significantly reduced. Based on these results, we isolated small molecular compounds, polysaccharides and protein from Shaoyao Gancao Decoction and their contents are 60.4, 700.7 and 207.2 mg·g^-1 respectively. We get the ratio, polysaccharide: small molecule = 11.6∶1, protein: small molecule = 3.4∶1, the precipitate is prepared in the state of boiling. The characterization results showed that the particle size of the precipitate will change significantly after co-heating, and the content determination results showed that the content of the six small molecular compounds which was free in solvent was significantly reduced after the formation of the precipitate. The acetic acid writhing experiment proved that the precipitate has a good analgesic effect, and effectively reduced the levels of inflammatory factors prostaglandin E2 and nitric oxide, and increased the level of anti-inflammatory factor interleukin-10. These results proved that the precipitate in Shaoyao Gancao Decoction is an important material basis for analgesic effect, and macromolecules such as protein and polysaccharide are the main components of the precipitate. The study of macromolecules in the precipitate of Shaoyao Gancao Decoction not only provides new ideas and methods for elucidating the pharmacodynamic material basis of Shaoyao Gancao Decoction, but also provides a reference for analyzing the scientificity of traditional decoction.

Methods In recent 5 years,in our hospital,136 cases of retained and regenerate hepaticolithiasis were treated by combination of hepatolobectomy with other operation, and these cases were analyzed retrospectivly. Results One patient died after operation (0. 7%),8 patients had other complications including: biliary fistuta(6 cases, 4.4%), subphrenic abscess (2 cases,1.5%). All cases were visited for 2.5 - 8.3 years, 115 (84.6%) cases had not any symptom, 6 (4.4%)cases had infection of biliary tract, 6(4.4%) cases had retained calculus, 9(6.6%) cases recurred calculus 2 -5 years after operation. Conclusion Retained and regenerate hepaticolithiasis should be treated by combination of hepatolobectomy with other operation and fiber choledochoscope and B ultrasound of operation, which can increase therapeutic effect.

OBJECTIVE: To investigate the clinical application and efficacy of ¹²⁵Ⅰ radioactive seeds implantation in the treatment of recurrent salivary gland carcinoma after external radiotherapy. METHODS: From July 2004 to July 2016, 43 cases of recurrent salivary gland carcinoma of the neck after external radiotherapy or surgery combined with external radiotherapy were treated. According to the conventional segmentation radiotherapy for head and neck cancer (once a day, 1.8-2.0 Gy each time, 5 days per week), the cumulative radiation dose of the patients in this group was calculated. In the study, 26 patients received 50-60 Gy, 7 patients received less than 50 Gy, 4 patients received 60-70 Gy, and 6 patients received more than 80 Gy (range: 80-120 Gy). The interval between the last external irradiation and local recurrence was 4-204 months, and the median interval was 48 months. Among them, 25 cases were treated with ¹²⁵Ⅰ radioactive seeds implantation only and 18 cases were treated with ¹²⁵Ⅰ radioactive seeds implantation after operation. The prescription dose was 100-140 Gy. The control rate, survival rate and disease-free survival rate were recorded to evaluate the side effects. RESULTS: The median follow-up time was 27 months (ranging from 2.5 to 149.0 months). Among them, the median follow-up time of adenoid cystic carcinoma patients was 31 months (range: 2.5-112.0 months), and the median follow-up time of mucoepidermoid carcinoma patients was 18 months (range: 5-149 months). The local control rates for 1, 3 and 5 years were 66.5%, 48.8% and 42.7%, respectively. The 1-, 3- and 5- year survival rates were 88.0%, 56.7% and 45.8%, respectively. The disease-free survival rates of 1, 3 and 5 years were 58.3%, 45.4% and 38.1%, respectively. There was no statistically significant difference in local control rate, survival rate, and disease-free survival between the radioactive seeds implantation group and the radioactive seeds implantation group after surgical resection. There were 2 cases of acute radiation reaction Ⅰ/Ⅱ and 3 cases of reaction Ⅲ or above. In the late stage of radiotherapy, there were 8 cases with Ⅰ/Ⅱ grade reaction and 3 cases with Ⅲ grade or above reaction. The incidence of radiation reactions of Grade Ⅲ and above was 7%. CONCLUSION ¹²⁵Ⅰ radioactive seeds implantation provides an alternative method for the treatment of recurrent salivary gland carcinoma after external radiotherapy. The local control rate and survival rate are improved on the premise of low incidence of side effects.

Aim To explore the role of endoplasmic re-ticulum stress( ERS) in Astragaloside Ⅳ-induced car-dioprotection against ischemia/reperfusion injury in rats. Methods A model of myocardial ischemia 30 min followed by 120 min reperfusion was made by liga-ting coronary artery in male Wistar rats. Rats were di-vided randomly into 4 groups: sham group, ischemia/reperfusion group, ERS inhibitor TUDCA group, As-tragaloside Ⅳgroup. Myocardial samples were collect-ed from the risk zones during ischemia and reperfu-sion, ERS was determined by measuring levels of glu-cose regulated protein 78 ( GRP78 ) , an established marker of ERS with Western blot. Immunofluorescence study was used to test GRP78 intensity with laser scan-ning confocal microscopy, TTC method was used to measure the infarct size,hematoxylin-eosin staining was used to observe the changes of morphological changes of myocardium. Results There was no statistical difference in GRP78 expression during ischemia com-pared to the sham group, but was markedly increased upon reperfusion. Astragaloside Ⅳ could mimic TUD-CA and significantly decreased the GRP78 expression, reduced infarct size and improved the morphology of myocardial tissue with a significant statistical difference compared with the control group ( P<0. 05 ) . Conclu-sions ERS is induced upon reperfusion but not during ischemia in isolated rat hearts. Astragaloside Ⅳ pre-vents myocardial reperfusion injury presumably by the inhibition of ERS.
