MIC,according to which,the antibiotics frequently used for treating respiratory infections were divided into three groups:Time-dependent(with minimal or no PAE),Concentration-dependent(with PAE),Time-dependent and Concentration-enhanced(with PAE),In addition,the most appropriate antibiotic administration methods are also explored respectively in the article.Finally,several measures of preventing emergence of resistance are proposed based on the theory of MPC.

The procedure of treating prostate cancer is as the following: After local prostatectomy or radiotherapy or local palliative therapy, androgen-dependent prostate cancer(ADPC) should be given first-line endocrinal therapy. Almost all patients will be developed from ADPC to hormone independent prostate cancer (HIPC) after 14 ～ 30 months, including androgen-independent prostate cancer(AIPC) and hormone-refractory prostate cancer(HRPC). Second-line endocrinal therapy and chemotherapy should be given, respectively. Antibone metastasis therapy is given when bone metastasis occurred. All medical methods should be used rationally and comprehensively to improve the management of prostate cancer.

The bactericidal activity of serum and cere brospinal fluid (SBA and CBA)of ceftroiaxone (CTRX), cefotaxime(CTX) cefuroxime(CFR) in the patients undergoing surgery of skull and brain were studied by means of microdi luted method. The results showed antibacterial activity of CTRX against, enterobactericeae in vitro or in serum and cerebrospinal fluid (CSF) was the highest, it is suggested that the schadule of CTRX per 12hr may be used in prevention and treatment of serious infections after surgery of skull and brain.The bacteria The SBA and CBA of CFR were less ,but its antibacterial spectrum was wide and bactezi cidal activity of CTX against gram positive strains and enterobactericeae in sencm and CSF were higher, CTX may be used in treatment of infections of nervous system caused by mixed bacteria, the cost was lower, so CFR may be selected in the moderate infections. The CBA was a synthesized guide reflexing the antibactieral activity and penetration into barrier, so it is impostand reference to select antibiotics of infection after surgery of skull and brain.

Objective To observe the effect of valsartan combined with salvia miltiorrhiza ligustrazine in treating early diabetic nephropathy(DN),looking for an effective method for the treatment of early DN.Methods 51 DN patients were divided into two groups,28 cases in the treatment group were treated with valsartan and salvia miltiorrhiza ligustrazine therapy,23 cases in the control group only received valsartan treatment.Fasting blood glucose before and after treatment (FPG),2h postprandial blood glucose (2hPG),glycosylated hemoglobin (HbA1 c),BUN,Scr,urine albumin excretion rate(UAER) index were detected.Results Before and after treatment,FPG,2hPG,HbA1c,UAER in the two groups had statistically significant differences (t =5.361,6.458,3.026,7.894,5.648,7.604,6.590,8.652,all P ＜ 0.05).After treatment,2hPG,HbA1c,UAER between the two groups had statistically significant differences (t =3.125,3.520,3.881,all P ＜ 0.05).No statistical difference was observed before and after treatment in two groups of BUN,Scr (P ＞ 0.05).Conclusion Valsartan combined with salvia tetramethylpyrazine in treatment of early DN was more effective than single valsartan treatment,and no significant adverse reactions was found in combined treatment.Therefore,the combined treatment can be used as a new method for clinical treatment of early DN.

Histological variants of papillary carcinoma are numerous,and most variants have the same clinical behavior with classical PTC.Howwver prognosis of a few variants are poor,such as Tall cell variant,Columnar cell variant,Solid/Trabecular variant etc.There are some controversy in the diagnosis of some variants.For example,Follicular variant is easily misdiagnosed as Follicular adenoma,Clear cell variant ma y beconfused with Renal cell carcinoma.Moreover,there are some divergences about proportion of cell and cell height in diagnosis of Tall cell variant,and so on.

Based on the systematic review on acupuncture improving the mechanism of central nervous system in animal model of myocardial ischemia in recent years, we analyzed the effects of acupuncture on medulla oblongata rVLM zone, hippocampus, hypothalamus, spinal cord segment and automalic to the mechanism of positively regulating myocardial ischemic, which provided a new way for the clinical treatment of myocardial ischemia and cardiovascular diseases.

Objective To investigate if apoptosis induced by arsenic trioxide(As_2O_3)on bladder cancer T24 cell line is related to the alteration of protein kinase C and cyclic adenosine monophosphate (PKC-cAMP)and its possible mechanism.Methods Apoptosis was studied by TUNEL method.Radio- immunoassay and enzyme immunoassay methods were used to detect the PKC-cAMP alteration in apoptotic process.The expressions and activation of caspase3 were observed by immunocytochemical method and Western blot.Results Atter 24-h drug treatment,the cell apoptosis induced by different concentrations of As_2O_3 was detected by TUNEL method.In control group,the apoptosis rate was 0.86%;PKC level was 2.55 pmol?min~(-1)??g~(-1);cAMP concentration was 22.56 pmol/ml;the expression rate of caspase3 was 8.01%.Compared with control group,the apoptosis rates of 5?mol/L and 10?mol/L As_2O_3 groups increased 8.51-fold and 13.33-fold,respectively;PKC Level decreased 59.22% and 64.71%,respectively;cAMP in- creased 5.34-fold and 4.23-fold,respectively;expression rates of caspase3 increased 3.96-fold and 6.76- fold,respectively.The differences were significant(P＜0.05).Compared with As_2O_3 groups,apoptosis rates of 5?mol/L and 10?mol/L As_2O_3+100nmol/L phorbol 12-myristate 13-aectate(PMA)groups decreased 40.22% and 45.58%,respectively;PKC increased 1.00-fold and 0.76-told,respectively;cAMP decreased 8.37% and 31.46%,respectively;expression rates of caspase3 decreased 51.09% and 65.03%,respective- ly.Activation of caspase3 was detected in As_2O_3-treated groups and As_2O_3+100 nmol/L PMA-treated groups;and activations of caspase3 in PMA-treated groups were weaker than those in As_2O_3-treated groups. Conclusions The antitumor mechanism of As_2O_3 may be the induction of bladder cancer T24 cell apopto- sis by decreasing PKC and increasing cAMP level.
