Objective To investigate the analgesic and anti-inflammatory effects of diuretic mixture and its bacteriostasis effect in vitro,and to provide scientific basis for clinical application.Methods Ear swelling test induced by xylene,twisting reaction test induced by acetic acid,capillary permeability increase in abdominal cavity of mice induced by acetic acid,and pain test induced by formalin were used to observe the analgesic and anti-inflammatory effects of diuretic mixture at high,middle and low doses (crude drug 18.0,9.0,and 4.5 g/kg).Bacteriostatic activities of diuretic mixture were tested by K-B paper disc diffusion method.Results Diuretic mixture alleviated ear edema in mouse model at high dose (P ＜ 0.01).Diuretic mixture at high,middle,and low dose could effectively decrease the twisting reaction (P ＜ 0.01),inhibit capillary permeability (P ＜ 0.05 or 0.01),and ease the ache degree of mice induced by formalin in the first phase (P ＜ 0.01),but there was no significant difference in the degree of pain intensity of phase Ⅱ.The inhibitory rates of diuretic mixture on Staphylococcus aureus and Escherichia coli were 95.04％ and 37.44％,respectively.Conclusion Diuretic mixture has significant effects on analgesia and anti-inflammation and against S.aureus and E.coli in vitro.

This study aimed to identify Belamcandae Rhizoma, Iridis tectori Rhizoma and their adulterants by ITS2 sequence. All the DNA samples of Belamcandae Rhizoma, Iridis tectori Rhizoma and their adulterants were extracted. The ITS2 sequence were succesfully amplified, and purified PCR products were sequenced. All the sequences were assembled using the CondonCode Aligner V3.7.1. The Kimura 2-Parameter (K2P) genetic distances and the Neighbor-Joining (NJ) phylogenetic tree were calculated by using MEGA5.1. Results indicated that the maximum intraspecific genetic distances of Belamcandae Rhizoma was 0, and the average GC content was 52.22%;the maximum intraspecific genetic distances of Iridis tectori Rhizoma was 0.004, and the average GC content was 67.87%. The maximum K2P intraspecific genetic distance of Belamcanda chinensis, Iris tectorum were both lower than the minimum interspecific genetic distance of adulterants. Additionally, the ITS2 sequences in each of these polytypic species were separated into pairs of divergent clusters in the NJ tree. The NJ tree based on ITS2 sequence indicated that Belamcandae Rhizoma, Iridis tectori Rhizoma and their adulterants could be distinguished clearly. It could be concluded that ITS2 barcode can be used to correctly identify Belamcandae Rhizoma, Iridis tectori Rhizoma from their adulterants, and ensure their safety in use.

BACKGROUND: Chronic pain after tension-free inguinal hernia repair is a common postoperative complication. An important cause of chronic pain is nerve injury. OBJECTIVE: To observe the effect of iliohypogastric nerve preposition on chronic pain after inguinal hernia repair and analyze its mechanics. METHODS: Totally 76 male inguinal hernia patients, from August 2013 to November 2016, aged 36-95 years in Second People’s Hospital of Lianyungang were selected. The patients were all treated with large-size polypropylene non-absorbable mesh insertion. The iliohypogastric nerve was placed in front of the mesh. Pain was followed up at 3, 6, and 12 months after operation. This study was approved by the Ethics Committee of Second People’s Hospital of Lianyungang. RESULTS AND CONCLUSION: (1) No chronic pain or recurrence was found in the 76 patients at 3, 6 and 12 months after surgery. (2) The pressure included vertical pressure and tangent pressure formed from intra-abdominal pressure on abdominal wall, directly affecting abdominal wall and artificial repair materials. This was the basic cause of the relative mechanical relationship between nerve and mesh. (3) The results showed that the tension-free inguinal hernia repair with the iliohypogastric nerve preposition could reduce the incidence of postoperative chronic pain, which may be related to the effect of postoperative abdominal pressure on tissue repair, especially the repair around the mesh.

Objective To develop a convenient, rapid and specific method using real-time fluorescent quantitative polymerase chain reaction (FQ-PCR) for detection of facioscapulohumeral muscular dystrophy(FSHD). Methods Genomic DNA was extracted and digested by restricted endonuclease EcoR Ⅰ , followed by agarose electrophoresis. The DNA (< 38 kb) was retrieved from agarose electrophoretic gels. The primers and probe were designed in D4ZA gene in chromosome 4. One hundred and fifteen subjects were examined by FQ-PCR using the retrieved DNA (<38 kb) as a template and the result was analyzed by fluorescent curve comparing with positive control. Results The results by FQ-PCR showed that 13 cases were positive in 16 FSHD cases whose EcoR Ⅰ fragment sizes were known, 75 cases were negative in 78 cases of normal controls, 15 cases were positive in 16 FSHD cases diagnosed clinically whose EcoR Ⅰ fragment sizes were unknown, and 3 cases were positive in 5 cases of relatives of FSHD patients. Consistency was checked using Kappa index between the 2 gene diagnostic tests for FSHD (FQ-PCR test and the traditional Southern blotting test), and between the 2 diagnostic criterions (gene diagnosis by FQ-PCR and clinical diagnosis). The results were statistically significant (κ = 0. 765, P = 0. 002 ; κ = 0. 844, P = 0. 000). Conclusions A new genetic diagnostic method of FSHD by FQ-PCR was developed, which was more simplified and reliable compared to the time-consuming, radioactive Southern blotting. It could also detect the D4Z4 arrays in cases having deletion of p13E-11 as well as the interchromosomal exchange between 4q35 and 10q26. The new method of FQ-PCR for FSHD may be extended to utilize clinically in future.

Objective:To study the effects of compound preparation of Fanshiliu on lipid metabolism and pancreatic pathological changes in type 2 diabetes mellitus(T2DM)rats with insulin resistance. Methods:After fed with high-calorie food for 8 weeks,the rats received intraperitoneal injection with low dose of streptozotocin(STZ)to induce T2DM animal model,and then the rats were randomly divided into the model group,metformin group,high and low dose group of compound preparation of Fanshiliu. The normal group was given ordinary feed. The rats were sacrified after intragastric administration for six weeks,and fasted for 12 hours after the last administration. The lipid and lipoprotein indices were detected,and pathological morphology of pancreatic tissue was observed. Results:Compared with those in the model group,TC,TG,LDL-C and FFA in each treatment group were reduced,and HDL-C was increased(P < 0. 05). Fanshiliu high dose group and metformin group had obvious hypoglycemic and lipid-lowering effects. The results of pathological morphology of pancreatic tissue under a light microscope showed that the damage was the most obvious in the model group. Compound preparation of Fanshiliu groups and metformin group showed damage in varying degrees. Conclusion:Fanshiliu preparation can effectively adjust blood lipid levels,enhance the insulin sensitivity and reduce damage in pancreas in T2DM rats.
