OBJECTIVE To investigate the reasons of infusion reaction. METHODS The liquid and disposable infusion tubes were tested by limulus amebocyte lysate(LAL).Blood samples were collected when infusion reaction occurred and the bacteria in blood culture were detected. RESULTS A total of 58 cases of infusion reactions within two years were from clinical department.LAL of liquid infusion was positive in 5 cases.Two isolations were identified from liquid infusion respectively.LAL was negative and no isolation for the unsealed bottle of liquid drugs with same batch number.LAL was negative for samples of same lot infusion tubes.The main drugs caused infusion reaction were refined medical herbs,large molecule substance,blood products and the medicine contained potassium ion.53.4% infusion reactions occurred in autumn.The seniles had high incidence.Bacteria were isolated from 5 patients in blood culture after liquid infusion. CONCLUSIONS More than one reason that cause infusion reaction.It is important to reduce incidence of infusion reaction through quality control of infusion tubes and aseptic process in infusion.

Objective To study the adiponectin mRNA expression in omental adipose tissue of type 2 diabetes. Methods RT-PCR method was used to examine the adiponectin mRNA expression. Fasting levels of BG,TG,TC,HDL-C,LDL-C of all the subjects were checked and their blood pressure,height,weight,waist circumference,hip circumference were measured to calculate BMI,WHR. Results The adiponectin mRNA expression in omental adipose tissue was decreased in diabetes group versus non-diabetes group (P<0.05),and negatively correlated with WC,TG,FBG,WHR(P<0.05). Conclusions Type 2 diabetic patients show lower expression of adiponectin mRNA in omental adipose tissue than that of non-diabetic control.WC,TG,FBG, WHR and course of disease are correlated with adiponectin mRNA expression and insulin resistance

8 patients, 6 males and 2 females, aged 26-56 years, with delayed neurologic sequelae following CO intoxication, were treated. The lucid intervals before the appearance of neurological sequelae varied from 5 days to 3 months, and the course of disease lasted for 7 days to 2.3 years. The clinical manifestations were mainly dementia, mutism, urinary or fecal incontinence, and gait disturbance. Among the 8 patients, clinical cure was obtained in 5 and improved in 3 after intrathecal oxygen administration.

BACKGROUND:Being used in senile intertrochanteric fracture, the third generation of Gamma nail may isolate fracture fragments and it is difficult to be secured in the rotor, so the stability is poor. Varus deformity easily appears, which is difficult to support or satisfactorily reset. OBJECTIVE:To compare the effects and stability of the proximal femoral locking plate and the third generation of the gamma nail in the treatment of stable intertrochanteric fracture. METHODS:(1) A total of 64 patients with intertrochanteric fractures were respectively treated with the third generation of the gamma nail fixation (n=32) and proximal femoral locking plate fixation (n=32). Fracture reduction and healing were assessed using anteroposterior and lateral radiographs. Femoral rotor varus angle and intertrochanteric medial inclination received biomechanical measurement. (2) Eight femoral specimens whose shape and size were approximated were selected to be randomly assigned to Gamma 3 group and proximal femoral locking plate group (n=4), which respectively received Gamma 3 fixation and proximal femoral locking plate fixation. After axial compression test and destruction test, load-displacement curve was drawn. The maximum yield load value was calculated by torsion test. RESULTS AND CONCLUSION:Operative time and intraoperative blood loss were significantly more in the proximal femoral locking plate group than in the Gamma 3 group (P < 0.05). The fracture quality assessment results were better in the proximal femoral locking plate group than in the Gamma 3 group (P < 0.05). The axial stiffness and corresponding torque of various torsion angles were smaler in the proximal femoral locking plate group than in the Gamma 3 group (P < 0.05). Experimental results indicated that in the course of fixating intertrochanteric fracture merged with greater trochanter fracture, the proximal femur locking plate has obtained more biomechanical stability.

Objective To compare the clinical therapeutic effects of continuous veno-venous hemofiltration (CVVH) and continuous veno-venous hemodiafiltration (CVVHDF) for treatment of patients with multiple organ dysfunction syndrome (MODS).Methods A prospective observation was conducted, seventy patients with MODS admitted to the Department of Critical Care Medicine of the Affiliated Hospital of Zunyi Medical College from September 2013 to December 2016 were enrolled, and they were divided into a CVVH group and a CVVHDF group according to different treatment, 35 cases in each group. In the CVVH group, the ultrafiltration fluid flow rate was set at 1800 mL/h, while in the CVVHDF group, the flow rate was set at 2000 mL/h for both substitution fluid and dialysate, and the blood flow of the two groups was 150-180 mL/min. The changes of creatinine (SCr), urea nitrogen (BUN), pH value, HCO3-, helper T cell (Th1, Th2) and Th1/Th2 ratio were compared between the two groups before and after treatment for 24, 48 and 72 hours.Results With the extension of time, SCr, BUN were reduced in both groups after treatment compared to those before treatment, 72 hoursafter treatment they reached the lowest value, and the degree of change in CVVHDF group was more significant than that in CVVH group [SCr (μmol/L): 150.62±32.09 vs. 180.41±30.52, BUN (mmol/L): 7.31±2.19 vs. 9.06±2.36. allP < 0.05], after treatment; the pH value, HCO3- level in the two groups had a tendency at first elevated and then lowered, 48 hours after treatment they reached the peak values, compared with those before treatment, the differences were statistically significant [CVVH group: the pH value 7.42±0.08 vs. 7.25±0.10, HCO3- (mmol/L) was 22.49±5.11 vs. 15.65±4.16; CVVHDF group: pH value 7.41±0.04 vs. 7.24±0.11, HCO3- (mmol/L) 23.24±4.78 vs. 15.65±4.16, allP < 0.05], 72 hours after treatment, they began reduced (CVVH group: pH value, HCO3- were 7.39±0.09, 22.35±4.91 respectively, CVVHDF group: pH value, HCO3- were 7.38±0.06, 23.13±4.61 respectively), but they were still significantly higher than those before treatment, and at each time point compared between the two groups, no statistical significant difference was seen (allP > 0.05). With the extension of therapeutic time, Th1, Th1/Th2 in two groups were gradually elevated after treatment, and 72 hours after treatment they reached the peak values; Th2 showed a trend of gradual decrease and after 72 hours of treatment it reached the lowest value, and the changes in CVVHDF group were more significant than those in CVVH group [Th1 (×10-2): 1.51±0.12 vs. 1.21±0.11, Th2 (×10-2): 1.64±0.65 vs. 1.70±0.18, Th1/Th2: 0.91±0.14 vs. 0.71±0.15, allP < 0.05].Conclusion Both CVVH and CVVHDF can effectively remove inflammatory mediators and metabolic products, adjust the balance of acid and base, regulate immune system in the body of patients with MODS, and the CVVHDF is more effective than CVVH.

Objective To investigate the kinds of isolates and the causes of bloodsream infection.Methods A total of 4 459 blood samples were cultured by BacT/Alert 3D240. The isolates were identified by API system.Results 247 strains were isolated from 246 patients. The isolates included Gram-negative bacteria (66.0%), Gram-positive bacteria (30.4%) and fungi(3.6%). E. coli, Salmonella paratyphi A , Salmonella typhi and Staphylococcus sp. not-Staphy. aureus were the main pathogen. The causes of bloodstream infection resulted from non-surgical disease, surgical disease, and others were 82.5%, 4.1% and 13.4%, respectively. The major symptom of blood infection was fever, which was presented in 41.5% of positive blood culture cases. 77.6% of Salmonella sp. was isolated from the patients of the department of respiratory and the department of emergency. E. coli was mainly isolated from the patients of the department of nephrolgy, haemotology and surgical department. Staphycoccus sp.not-Staphy. aureus was mainly isolated from the patients of the department of respiratory and pediatrics. The positive blood culture rate in 12,24,36,48,72,96 h were 24.4%,74.0%,87.4%,93.1%,97.2%, and 99.2% respectively.The coincidence rate of positive blood culture detected under microscope and identified by API system was ~99.6%. Conclusion Automated blood culture systems were important apparatus for diagnosis of bloodstream infection.

Objective To compare using the transabdominal route versus the transoral route in establishing naso-biliary drainage in laparoscopic surgery.Methods The combined use of laparoscopy with choledochoscopy and duodenoscopy to establish naso-biliary drainage was carried out in 204 patients with gallbladder and common bile duct calculi.In 162 patients,the naso-biliary drainage was established transabdominally and in 42 patients it was established transorally.The success and the complication rates in the two groups were compared.Results Of 162 patients using the transabdominal route,4 patients failed.There were 6 patients (3.7％) who had no output from the nasobiliary drain.There were 3 patients (1.8％) who had only intestinal juice outflow from the nasobiliary drain.Primary closure failed in 3 patients (1.8％),all resulting in bile leak.Pancreatitis occurred in 2 patients (1.2％) after the operation.There was 1 patient (0.6％) whose nasobiliary drain was wrongly ligated.Of 42 patients with nasobiliary drainage using the transoral route,6 patients failed.There was 1 patient (2.4％) who had no output from the nasobiliary drain.There was 1 patient (2.4％) who had intestinal juice output from the nasobiliary drain.Primary closure failed in 1 patient (2.4％) with resultant bile leakage.Pancreatitis occurred in 4 patients (9.5％) after the operation.The success rate of establishing a nasobiliary drainage in the transabdominal group was significantly higher than that in the transoral group,but the complications were less.Conclusions Nasobiliary drainage established through the transabdominal route in laparoscopy surgery for patients with gallbladder and common bile duct calculi was technically easier and had a high success rate.It had less complications.

Objective To verify the genes screened by the polymerase chain reaction (PCR) chip of cell cycle. Methods The colon cancer cells SW480 were randomized into two groups, the test group (with gastrin stimulation) and con-trol group (without gastrin stimulation). The method of Western blot was used to detect the expression of calcylin binding pro-tein/Siah-1 interacting protein (Cacybp/SIP) before and after gastrin stimulation. The differential expression genes, cyclin de-pendent kinase 8 (CDK8) and cyclin dependent kinase subunit (CKS2), were verified by using real-time quantitative PCR (qRT-PCR). Results It was found that before the stimulation, CacyBP/SIP was located and expressed in cytoplasm, and then in both cytoplasm and nucleus after gastrin stimulation. The qRT-PCR results of CDK8 and CKS2 genes were consis-tent with those of microarray detection. The expressions of CDK8 and CKS2 were up-regulated (P < 0.05). Conclusion The stimulation of human gastrin can lead to the nuclear translocation of CacyBP/SIP. The results of microarray are reliable, and the differentially expressed genes screened through gene chip deserve further study.

Objective To investigate the effect of ajoene on thrombosis and explore the possible mechanism.Method SD rats were randomly divided into five different groups and administered ajoene in 7d.The effect of ajoene on thrombosis in rats was observed with the thrombogenesis model of artery-vein bypass.The serum level of vascular cell adhesion molecule-1(VCAM-1) and P-selectin(Ps)were measured.To observe the effect of ajoene on platelet aggregation,arachidonic acid was used to induce platelet aggregation and platelet function was evaluated by turbidimetry in rabbit.Results Ajoene significantly inhibited the the thrombosis of artery-vein bypass in rats and reduced rate of platelet maximal aggregation and decreased the P-selectin concentration in serum at 25,50,75mg/kg (P

Objective To retrospectively study the serum IgG and IgM antibodies against toxoplasma, rubella virus, cytomegalovirus and herpes simplex virus type 1&2 in various populations, and analyze the clinical values.Methods From 2008 to 2015, 2 661 pregnant women, 324 infertile women, 2 492 women with abnormal pregnancy history, 623 women with recent abnormal pregnancy, 261 infants with intrauterine growth retardation and other diseases, 170 women for preconceptual examination, and 702 women for physical examination in Beijing were included .Commercial EIA kits were used to detect serum IgG and IgM antibodies to toxoplasma, rubella virus, cytomegalovirus and herpes simplex virus type 1&2. Positive reactions of IgM antibodies to any pathogens were re-tested with another kind of commercial EIA kit. PEMS3.1 software was used for statistical analysis.Results The prevalence of serum IgG or IgM antibodies against toxoplasma, rubella virus, cytomegalovirus and herpes simplex virus type 1& 2 were found within 0.7%-1.6%(0-1.2%) , 85.3%-92.0% ( 0.4%-2.7%) , 89.1%-94.9% ( 0.7%-1.7%) , 74.8%-86.0% ( 0 -0.7%) , 8.1% -17.4% ( 0 -4.1%) respectively in the studied population groups.The prevalence of TORCH IgG and IgM antibodies were not found to be higher in both populations with past suspicious exposure ( infertile women and women with abnormal pregnancy history ) and recent suspicious exposure ( women with recent abnormal pregnancy and infants with intrauterine growth retardation and other diseases) than that in pregnant women and women for preconceptual and physical examination. Conclusion No associations between TORCH infections and the suspicious exposure were found in the populations above.
