OBJECTIVE:To analyze the causes of drug quality events took place in our hospital so as to provide reference for the improvement of drug quality.METHODS:Systematic investigations were performed on 150 batches of drugs that had shown quality problems during 2005 and 2006 in our hospital and the possible reasons accountable for the problems were analyzed.RESULTS & CONCLUSIONS:The quality problems were originated from 3 links including production,distribution and use of drugs,and manifested as improper or wrong packaging,labels or package inserts,inappropriate handling,and improper operation of medical staff etc,which worth the highest alert of the concerned departments.

Surgery is the main treatment of esophageal cancer. Esophagectomy by right transthoracic approach is recently recom-mended in China. Minimally invasive esophagectomy is feasible and safe with low perioperative morbidity and offers results that are as good as open thoractomy. Multimodal treatment, especially neoadjuvant chemoradiotherapy or chemotherapy, may improve surviv-al and has become one of the standard treatments for locally advanced esophageal cancer. Fast-track esophagectomy may reduce length of hospital stay, perioperative morbidity, and hospital charges. The surgery of esophageal cancer tends to be minimally invasive, individual, comprehensive, and standardized.

Objective To analyse the effect of Danhong injection on serum levels of cystatin C (CysC), homocysteine (Hcy) and inflammatory factors in elderly patients with chronic heart failure.Methods Fifty-two elderly patients who were diagnosed with chronic heart failure in our hospital were collected.All patients were randomly divided into experimental group and control group, 26 cases in each group, the control group were given conventional therapy, the experimental group received Danhong injection adjunctive therapy on the basis of the control group.After treatment, the serum levels of CysC, Hcy, nuclear transcription factorκB (NF-κB), interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α), heart function and incidence of adverse reactions were detected in all patients.Results After treatment, compared with control group, the serum levels of CysC and Hcy were lower, the serum levels of NF-κB,IL-1βand TNF-αwere lower in the experimental group, and the levels of left ventricular ejection fraction ( LVEF) and stroke volume (SV) were lower in the experimental group, there were significant difference between two groups (P<0.05).There was no significant difference in the incidence of adverse reactions between the two groups.Conclusion The Danhong injection therapy could significantly reduce the serum levels of CysC, Hcy and inflammatory factors in elderly patients with chronic heart failure,reduce the inflammatory reaction, improve the heart function, and have high safety.

Objective To explore the antagonistic effect of Schistosoma japonicum soluble adult worm antigen (SWA)and solu-ble egg antigen (SEA)in the mice with type 1 diabetes.Methods The 24 successful modeling type 1 diabetes mice were randomly divided into three groups (A,B,C group,n=8).SWA and SEA of Schistosoma japonicum were prepared.Mice in A group were immunized by abdominal subcutaneous multi-point injection SWA.Mice in B group were immunized by abdominal subcutaneous multi-point injection SEA.And mice models of C group were immunized by PBS instead of antigen through abdominal subcutaneous injection.The mice got immunization once a week,a total of four times.4 weeks later,the mice were sacrificed,and serum speci-mens were collected for the determination of serum levels of IL-4 and IFN-γby double-antibody sandwich ELISA,while pancreas tissues were collected and the pathological changes were observed.Results The serum IL-4 level of B group [(23.87 ±4.85)pg/mL]was higher than C group [(4.39 ± 0.56 )pg/mL],with significant differences (P < 0.01 ),while the serum IFN-γ level [(271.85±26.04)pg/mL]was lower than C group [(362.79 ±32.50)pg/mL],also with significant differences (P <0.01).The serum IL-4 and IFN-γof A group were (5.09±0.37)pg/mL and (379.56±34.47)pg/mL,which had no difference with C group (P >0.05).The islet structure of mice in B group was not intact,however,the lymphocytic infiltration in B group was less than C group,and there was no lymphocytic infiltration in pancreatic islets in B group.Compared with C group,the pancreas of mice in A group did not have significant changes,lymphocytes infiltration was still visible in islets.The number of residual islet cells de-creased,and visible minority islet structure was destroyed.Conclusion SEA of Schistosoma japonicum has certain antagonism effect on type 1 diabetes in experimental mice.Its mechanism may be the reduction of Th1 response and the enhancement of Th2 response through increasing IL-4 level and decreasing IFN-γlevel.

Obesity is not only the high risk factor of diabetes mellitus,coronary heart disease and hypertension,but also a cause of renal damage.Diabetic nephropathy is one of the most frequent chronic microvascular complications of diabetes mellitus,and one of the leading causes of end-stage kidney failure.It is documented that the obese patients with type 2 diabetes may have obviously multiple metabolic abnormalities and are more prone to develop diabetic nephropathy.This article summarized the pathogenetic mechanisms of kidney injury in diabetic obese patients and provided some ideas in the medical therapy of diabetic nephropathy.

Objective:To study the effect of sensory nerve on fracture of mandible and try to find the possible mechanism.Methods:Thirty-two China rabbits were used and divided into two groups for study.They all suffered from a standardized fracture in the left mandible,and half of them with inferior alveolar nerve section(IANS)or without.The callus were stained to observe the expression of substance P(SP)by immunochemistry and analysed by a computerized-graph analysing system.Results:Immunoreactivites of substance P occurred weakly on Day 7 and 14 after operation,and became stronger at late stage in IANS group.On the contrary,stronger immunoreactivites of substance P occurred at the early stage,less on day 21 posttrauma and stronger again on day 28 in control group.The strongest immunoreactivites at each stage occurred mainly in bone marrow on day 28 posttrauma in both groups.There was significant difference in the expressions of substance P in the callus between the two groups(P

Objective: To study the meal qanity of the patient with chronic renal failure(CRF). Methods: The nutritional state of 140 CRF patients was researched,basing on the diet history.

Hapten-carrier protein conjugates were made using ciprofloxacin (CPFX) and two carrier proteins by 1-ethyl-3-(3- dimethylaminopropyl)-carbodiimide hydrochloride (EDC) method. Ultraviolet spectrophotometry were used to demonstrated that the molecule conjugate ratio of CPFX to ovalbumin (OVA) and bovine serum albumin (BSA) are 6:1 and 13:1 respectively. Nondenaturing gel electrophoresis results revealed that the conjugate band migrates differently from that of the carrier protein alone and of the EDC-treated protein when as few as 6 molecules of CPFX are attached to the carrier protein. The results indicate that nondenaturing gel electrophoresis and ultraviolet spectrophotometry can be employed to analyze the molecule coupling ratio of CPFX to carrier proteins qualitatively and quantitatively.

Objective To evaluate the value of the neutrophil-lymphocyte ratio (NLR) in elderly type 2 diabetic patients (T2DM) with coronary heart disease (CHD).Methods We performed a retrospective observational study on 228 patients undergoing coronary angiography in Guizhou Provincial People's Hospital from April 2014 to July 2015.Patients were divided into three groups:the simple T2DM group (n=77),simple CHD group (n=72),and T2DM complicated with CHD group (n=79).Meanwhile,70 healthy elderly subjects served as the control group.The white blood cell count,high-sensitivity C-reactive protein (hs-CRP) and other clinical and laboratory parameters were collected,and NLR was calculated.Risk factors for CHD in T2DM patients were determined by logistic regression analysis.Multiple stepwise regression analysis was adopted to identify factors influencing NLR.Results The white blood cell count,neutrophil count,NLR and hs-CRP level in the simple T2DM,CHD,and T2DM+CHD groups were higher than in the control group [(7.48 1.81) 109/L,(7.72± 1.89) 109/L,(7.98±2.12) 109/L vs.(6.22± 1.61) 109/L;(4.49±1.38) 109/L,(4.88±1.56) 109/L,(5.35±1.40) 109/L vs.(3.52±0.84) 109/L;(2.84± 0.77),(3.07±0.79),(3.34±0.83) vs.(1.58±0.42);(2.92±0.65) mg/L,(3.20±0.86) mg/ L,(4.98±1.10) mg/L vs.(1.105±0.23) mg/L;respectively,P＜0.05 or P＜0.01].The lymphocyte count in the simple T2DM,CHD,and T2DM+CHD groups were lower than in the control group [(1.57±0.41) × 109/L,(1.58±0.40) × 109/L,(1.61±0.48) × 109/L vs.(2.22± 0.51) × 109/L,P＜0.05].NLR and hs-CRP levels in the T2DM+CHD group were higher than in the former two groups (all P＜0.05).Pearson correlation analysis showed that NLR was positively correlated with the Gensini score and hs-CRP level (r=0.7455 and 0.7792,both P＜0.01).Logistic regression analysis showed that NLR,hs-CRP levels and glycosylated hemoglobin A1c (HbA1c) were the risk factors for CHD in T2DM patients (OR=4.331,3.997 and 2.928,all P＜0.05).Multiple stepwise regression analysis showed that NLR was positively correlated with fasting plasma glucose,HbA1 c levels and systolic blood pressure (β' =0.3133,0.4720 and 0.3069,all P＜0.05).Conclusions NLR may be a valuable predictive factor for CHD in elderly T2DM patients.
