Pelvic inflammatory disease sequela (chronic pelvic inflammation) is one of the diseases that affect women's health conditions, and leads to large economic burden. Chinese Material Medica (CMM) plays an impor-tant role in treating pelvic inflammatory disease sequela (chronic pelvic inflammatory). However, due to the lack of Evidence-based Pharmacoeconomic Evaluation Technical Essentials of CMM in Treatment of Pelvic Inflamma-tory Disease Sequela (Chronic Pelvic Inflammatory), non-standard phenomenon often appears in the research liter-ature, such as the selection of research methods, viewpoint of research, determination of cost, effect and utility. Thus, the publish of Evidence-based Pharmacoeconomic Evaluation Technical Essentials of CMM in Treatment of Pelvic Inflammatory Disease Sequela (Chronic Pelvic Inflammatory) is essential for the pharmacoeconomic evalua-tion of CMM in treating pelvic inflammatory disease sequela (chronic pelvic inflammatory).

In order to simultaneously remove carbon and nitrogen from organic-rich wastewater, we used an up-flow anaerobic sludge bed/blanket (UASB) reactor that was started up with anammox with high concentration of carbon and nitrogen by gradually raising the organic loading of influent. We optimized the removal of nitrogen and carbon when the chemical oxygen demand (COD) concentration varied from 172 to 620 mg/L. During the entire experiment, the ammonium and total nitrogen removal efficiency was higher than 85%, while the average COD removal efficiency was 56.6%. The high concentration of organic matter did not restrain the activity of anammox bacteria. Based on polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) and tapping sequencing analyses, the Planctomycete, Proteobacteria, Chloroflexi, Chlorobi bacteria are detected in the UASB reactor, which indicated complex removal pathway of carbon and nitrogen coexisted in the reactor. However, a part of Planctomycete which referred to anammox bacteria could tolerate a high content of organic carbon, and it provided help for high performance of nitrogen removal in UASB reactor.

To study the enrichment regulation of anammox bacteria during the whole start-up process of anammox reaction, two reactors with addition of carries of Spherical Plastic (SP) and Bamboo Charcoal (BC) and one without carrier (CK) were used to start anammox reaction. Then FISH and q-PCR analyses for the growth of all anammox bacteria were conducted during the operational process. The results indicate that the number of anammox bacteria in all reactors increased with time during the whole start-up process, which was consistent with the removal rate of ammonium and nitrite. On day 123 of stable phase, the percent of anammox cells in the sludge of CK, SP and BC accounted for 23.3%, 32.6% and 43.7%, respectively. The number of anammox bacteria 16S rRNA gene copies was (25.64 +/- 2.76) x 10(7), (47.12 +/- 2.76) x 10(7) and (577.99 +/- 27.25) x 10(7) copies g(-1) VSS in the sludge of CK, SP and BC, respectively. Carrier addition could dramatically increase enrichment of anammox bacteria. BC addition significantly increased the anammox bacteria number in the UASB reactor which resulted in the acceleration of the anammox start-up process. In addition, the max specific growth rate and the minimum doubling time were 0.064 d(-1) and 10.8 d in BC reactor. The max specific growth rate of anammox bacteria in BC reactor was 1.78 times and 1.88 times greater than that in CK and SP reactor, respectively. Therefore, the FISH and q-PCR analyses were suitable for determining the enrichment regulation of anammox bacteria during the start-up time, while a bit of differences in results existed between the two analytical methods due to the difference in analysis targets.

Objective To evaluate the role of serine-threonine kinase (Akt)/glycogen synthase kinase-3 beta (GSK-3β) signaling pathway in isoflurane preconditioning-induced inhibition of mitochondrial permeability transition pore protein (mPTP) opening during myocardial ischemia-reperfusion (I/R) in rats.Methods Ninety-six male Sprague-Dawley rats,aged 3-4 months,weighing 200-250 g,were randomly divided into 4 groups (n =24 each) using a random number table:control group (group C);I/R group;isoflurane preconditioning group (group IPC);Akt inhibitor MK-2206 group (group MK).Myocardial I/R was induced by occlusion of the anterior descending branch of the left coronary artery for 30 min followed by 2 h of reperfusion.In group IPC,1.5% isoflurane was inhaled for 30 min followed by 45 min washout,and then the model of myocardial I/R injury was established.In group MK,MK-2206 300 μg/kg (in dimethyl sulfoxide) was injected intraperitoneally at 30 min before isoflurane inhalation.At 2 h of reperfusion,8 rats were selected and sacrificed,and the hearts were removed for determination of myocardial infarct size.At 2 h of reperfusion,8 rats were selected,and blood samples were collected from the right internal jugular vein for determination of serum cardiac troponin Ⅰ (cTnI) concentrations.The rats were then sacrificed,and myocardial specimens were obtained for determination of the expression of phosphorylated GSK-3β (p-GSK-3β) in cytoplasm and mitochondria (by Western blot) and co-expression of p-GSK-3β with adenine nucleotide translocator (ANT),voltage-dependent anion channel or cyclophilin D in myocardial tissues (using co-immunoprecipitation).At 2 h of reperfusion,8 rats were selected and sacrificed,myocardial cells were obtained,and the opening time of mPTP was determined with a laser scanning confocal microscope.Results Compared with group C,the myocardial infarct size and serum cTnI concentrations were significantly increased,and the expression of p-GSK-3β in cytoplasm and mitochondria was up-regulated in I/R and IPC groups,the co-expression of p-GSK-3β with ANT was significantly down-regulated,and the opening time of mPTP was shortened in group I/R,and the co-expression of p-GSK-3β with ANT was significantly up-regulated,and the opening time of mPTP was prolonged in group IPC (P<0.05).Compared with group I/R,the myocardial infarct size and serum cTnI concentrations were significantly decreased,the expression of p-GSK-3β in cytoplasm and mitochondria was up-regulated,the co-expression of p-GSK-3β with ANT was significantly up-regulated,and the opening time of mPTP was prolonged in group IPC,and the opening time of mPTP was significantly prolonged (P<0.05),and no significant change was found in the other parameters in group MK (P>0.05).Compared with group IPC,the myocardial infarct size and serum cTnI concentrations were significantly increased,the expression of p-GSK-3β in cytoplasm and mitochondria was up-regulated,the co-expression of p-GSK-3β with ANT was significantly down-regulated,and the opening time of mPTP was shortened in group MK (P<0.05).No co-expression of p-GSK-3β with voltage-dependent anion channel or cyclophilin D was found in myocardial tissues.Conclusion The mechanism by which isoflurane preconditioning inhibits mPTP opening during myocardial ischemia-reperfusion is partially related to activation of Akt/GSK-3β signaling pathway in rats.

Objective To investigate the clinical pattern,therapeutic principle and influencing factors of interstitial pneumonia in renal allograft recipients.Method The general information,clinical manifestation,treatment and outcomes of 30 recipients with interstitial pneumonia after renal transplantation from Nov.2006 to Dec.2013 were analyzed retrospectively.Result Twenty-nine of 30 patients developed interstitial pneumonia between 2 to 6 months post-transplant.The total course of the pneumonia lasted for 34.9 ± 7.5 days on average.Chest CT scans were used to monitor severity of interstitial pneumonia each week.The mean duration between the onset to the fastigium of pneumonitis was approximately 14.8 ± 1.9 days.The mean duration of the fastigium lasted for 7.3 ±3.6 days,after that the patients usually started to recover.Deteriorated chest CT scan findings and long terms of the fastigium usually indicated poor outcomes.The mean duration of the recovery period was 13.1 ± 3.7 days.After adjusted administration of methylprednisolone,antibiotics,antifungal agents,nutritional support as well as immunosuppressive drugs,23 patients with mild and moderate pneumonia by the chest CT scans were cured and discharged.However,4 of the 7 patients with severe pneumonia by the chest CT scans died.Conclusion The progression of interstitial pneumonia after renal transplantation is characterized by a more consistent regularity.After adjusted administration of methylprednisolone,antibiotics,antifungal agents,nutritional support as well as immunosuppressive drugs,renal allograft recipients with interstitial pneumonia could obtain a good therapeutic effect without over-treatment.
