Objective To evaluate medical chemistry adhesive in tension-free herniorrhaphy for inguinal hernia. Methods In this study, 100 patients with primary unilateral inguinal hernia were assigned to study group ( n = 50) and control group ( n = 50) during Jun. 2009 and Dec. 2009. Medical chemistry adhesive (n-butyl-2-cyanoacrylate, NBCA) was used in Lichtenstein tension-free hernia repair in study group and suture procedure was used in control group. Patient demographics, operation time,postoperative length of stay, visual analogue scale ( VAS ) score 24 hours after surgery, incidence of postoperative chronic pain and hematoma, recurrence rate, and other complications were compared between the two groups. Results The duration of follow-up ranged from 12 months to 18 months. There were no recurrences or wound infection in the two groups. In study group, no patient complained of chronic pain postoperatively, whereas in the control group, 6 patients ( 12% ) had a significant chronic pain. In study group, 2 patients (4%) had local hematoma after operation, whereas there were 8 ( 16% ) in the control group ( P < 0. 05 ). There were no significant differences between the 2 groups in postoperative length of stay ( P > 0. 05 ), but the operation time and postoperative VAS score in study group ( 38 ± 5 min and 2. 5 ± 0. 6)were lower than in the control group (42 ± 5 min and 2. 8 ± 0. 8 ), ( P < 0. 05 ). Conclusions Application of medical chemistry adhesive in tension-free herniorrhaphy for inguinal hernia is associated with less postoperative pain, lower incidence of hematoma, less postoperative chronic pain and shorter operation time.

Objective To establish a multiplex real-time PCR mothed for rapid detection of seven species of intracranial bacteria after surgery. Methods Firstly ,the Gram′s identification was deter mined. Secondly , according to the results of Gram identification ,the bacterium was typed by the specific primers and probes to deter mine the distribution of bacteria. Simul taneously ,the sensitivity and specificity of this method were verified by making intracranial infected sim ulated samples and contrasting national standard method. Results The method established could complete detention within 4 hours with a good specificity. Staphylococcus aureus,Streptococcus pneumoniae ,Escherichia coli ,Pseudomonas aeruginosa pseudomonas ,Klebsiella pneumoniae and Acinetobacter baumannii could be detected at concentrations of ≥102 CFU/mL. Enterococcus faecalis could be detected at concen-trations of≥103 CFU/mL. The lowest detection limita of this method is higher than culture method for Streptococcus pneumoniae. Conclusions Real-time Multiplex PCR method was with high sensitivity and specificity. It reduced the detection time greatly and has great value in early diagnosis of bacteria in intracranial infection. It should be of great significance for guiding clinical treatment.

OBJECTIVE:To prepare Frovatriptan succinate film-coated tablet,and investigate its in vitro dissolution behavior. METHODS:Using lactose monohydrate,microcrystalline cellulose,dioxide,silica,sodium carboxymethyl starch and magnesium stearate as accessories,Frovatriptan succinate tablet was prepared. Using opadry premix spray-coating liquid,Frovatriptan succinate film-coated tablet was prepared. Single factor test was used,using moisture,angle of repose,rigidity,friability,disintegration time and dissolution rate as indexes,to screen the formulation;using dissolution degree as index,coating material dosage was screened. The dissolution curves in vitro of self-made tablets and imported tablets in water,0.1 mol/L HCL,pH of 5.5,6.8 phos-phate buffer solutions were compared. RESULTS:The optimal formulation of Frovatriptan succinate uncoated tablet was as follow as frovatriptan succinate 3.91 mg,lactose monohydrate 99.18 mg,microcrystalline cellulose 33.06 mg,magnesium stearate 1.40 mg,sodium carboxymethyl starch 1.05 mg,silica 1.40 mg;optimal coating weighed quality was 2.0%-4.0%. In the 4 mediums, the dissolution behavior of self-made tablets and imported tablets were similar. CONCLUSIONS:Frovatriptan succinate film-coated tablet is prepared successfully,and its in vitro dissolution behavior is similar to the imported preparations.

This study is to investigate the effect of osthol on osteoclasts' activity, bone resorption as well as apoptosis in vitro, and explore the mechanism of osthol in preventing osteoporosis. Osteoclasts were separated from long-limb bones of new born rabbits, cultured in 24-well plate with glass slices and bone slices, and treated by 1 x 10(-5) mol x L(-1) osthol. Osteoclasts were identified by observing live cells with phase contrast microscope, HE staining, TRAP staining and toluidine blue staining of bone resorption pits. The numbers of bone resorption pits were counted as well as the surface area of bone resorption on bone slice. Osteoclasts were stained with acridine orange to detect the cell apoptosis. The ratio of apoptotic osteoclasts was observed under fluorescence microscope. The gene expression of RANKL, OPG, TRAP and p-JNK1/2 protein expression were examined using real time PCR and Western blotting, respectively. Comparing with the control group without osthol, the rates of apoptotic osteoclasts increased obviously and the number and area of bone resorption pits decreased evidently with 1 x 10(-5) mol x L(-1) osthol. There is significant difference between control group and experiment group treated by 1 x 10(-5) mol x L(-1) osthol. Therefore, the osthol through RANK+RANKL/TRAF6/Mkk/JNK signal pathway inhibits the osteoclasts activity, enhances osteoclasts apoptotic and inhibits the bone resorption.

Objective To measure 222Rn and 220Rn concentrations in the underground non-uranium mines in Shandong Province,and to estimate the annual effective dose to the miners.Methods Concentrations of 222Rn and 220Rn in selected gold,iron,coal and clay mines were determined by passive time-integrating detectors with CR-39.Activity concentrations of 226Ra,232Th and 40K were determined using gamma spectrometry equipped with HPGe detector.Results The average concentrations of 220Rn in the gold,iron,coal and clay mines were estimated to be 1200,280,120 and 40 Bq/m3,respectively.The activity concentrations of 226Ra,232Th,40K in the ores for gold,iron,coal and clay mines ranged the same as the soil in China.The annual effective dose due to radon exposure in gold and iron mine was 7.70 mSv and 1.74 mSv,respectively.The annual doses received by miners in the coal and clay mines were lower than 1 mSv.Conclusions Underground miners in some gold and iron mines should be treated as workers occupationally exposed to ionizing radiation.The measurement such as increasing ventilation should be implemented to reduce underground radon concentration in these mines.
