OBJECTIVE:To analyze the current situation and developing trend of drugs used in hospitals of Chengdu.METHODS:The data of drugs purchased by 16 hospitals in Chengdu in the years 1997~2000 was collected and analysed.RESULTS:The drug expenses increased faster in years 1998~1999 and the drug expense in 2000 was 3 times as much as that in 1997.The proportion of sum of money spent on anti-infectives was decreasing year by year,which equaled that in developed cities of east China.CONCLUSION:The sum of money of drugs consumed will increase year by year,however,the growth rate may decrease.The proportion of consumption of imported drugs will continuously decrease.

Objective To study the effect of transcutaneous electrical acupoint stimulation (TEAS) on emergence agitation in children undergoing cochlear implantation.Methods Sixty patients (age range,1-4 years) scheduled to undergo pediatric cochlear implantation were enrolled and randomized into the TEAS group (group T,n =30) that received continuous TEAS and the control group (group C,n =30) that did not receive TEAS.Anesthesia time,operation time,change in blood flow dynamics during the perioperative period,extubation time,and PACU stay time were recorded.The incidence of emergence agitation and postoperative nausea and vomiting (PONV) was monitored.Results No significant intergroup differences were observed in age,sex,weight,operation time,and PACU stay time (P > 0.05).The MAP and HR in group T were lower than those in group C at different time points such as 30 min after the start of surgery,the end of the surgery,the extubation and 5 min after extubation,and the difference was statistically significant (P < 0.05).The FPS-R,FLACC,and PAED scores in group T were lower than those in group C at different time points within 30 min after exmbation (including the time of extubation),and the difference was statistically significant (P < 0.05).Extubation time,anesthesia time,and incidence of PONV were lower in group T than in group C,and the difference was statistically significant (P < 0.05).Conclusion TEAS combined with general anesthesia significantly reduces the incidence of emergence agitation in children undergoing surgery for congenital hearing loss;it also helps control hypotension,reheve dramatic hemodynamic changes during the waking period,and reduce the incidence of PONV.

Objective:To analyze risk factors of breast ductal carcinoma in situ (DCIS) with microinvasion (DCIS-MI) and explore suitable axillary lymph node surgery treatment for patients with DCIS-MI. Methods:The clinical characteristics, such as age, menopausal status at diagnosis, size of breast mass, and pathology reports of 45 patients with breast DCIS or DCIS-MI treated at Jinling Hospital, Medical School of Nanjing University from February 2013 to February 2016, were retrospectively collected and analyzed statistically to deter-mine the risk factors associated with microinvasion. Results:Premenopause (P=0.006), tumor size≥3.15 cm (P=0.006), and family his-tory of malignant tumor (P=0.002) were proven risk factors of DCIS-MI. Conclusion:Patients with clinical palpable axillary mass, pre-menopause, large breast mass, and family history of malignant tumor demonstrated high possibility of DCIS-MI. Hence, sentinel lymph node biopsy should be performed. Axillary lymph node dissection is highly recommended to patients whose main symptom is palpable axillary mass.

Objectives To evaluate the application of preoperative endoscopic ultrasonography ( EUS) in assessment of invasive risk and selection of therapeutic modalities for gastric stromal tumors ( GST).Methods The clinical data of 135 patients with GST admitted in our hospital from January 2011 to January 2012 were retrospectively analyzed.The invasion extent of GST was assessed by image of EUS before surgery, and compared with pathological results after surgery; the Fletcher 4-tier system was used for predicting the aggressiveness of GST.The selection of therapeutic modalities in 38 patients, who underwent surgical treatment was analyzed.Results No specific clinical manifestations were noticed , but some patients with enormous GST had symptoms of ulcer , hematemesis , and melena.Among 135 patients 97 cases received conservative treatment and followed up;in remaining 38 cases, according to invasion risk assessed by EUS, there were 9 cases in low risk, 18 in intermediate risk and 11 in high risk.The surgical modalities were selected based on the risk assessment:endoscopic therapy was performed in 15 cases, laparoscopic with gastroscopic surgery in 17 cases and laparotomy in 6 cases.The coincidence rate of diagnosis between preoperative EUS and postoperative pathological examination was 79.0%.Conclusions Preoperative endoscopic ultrasonography is of value in assessment of invasion risk and selection of appropriate therapeutic modalities for gastric stromal tumors.

Objective:To study effects of neuroligin (NLG) on the proliferation and apoptosis in human neuroblastoma SH-SY5Y cells.Methods:The SH-SY5Y cells were cultured in vitro for 24 hours,and then transfected with NLG siRNA at dose of 50,100,200 μmol/L,respectively.MTT procedure was used to detect the cell proliferation,and expression levels of apoptosis gene including Bax or Bcl-2 and Bcl-xl were measured by RT-PCR.Results:Compared to control groups proliferation of SH-SY5Y cells were distinctly inhibited after NLG siRNA transfection accompany with a dose-dependent,which was caused by activation of apoptosis.Conclusions:NLG protect neuron by inhibiting apoptosis.

Objective To continuously draw blood from caudal vein of SD rats which controlled by the homemade holder with an im-proved method, and the effects of this method was evaluated according to the relevant indicators. Methods The 24 SD rats should be drew the blood from the caudal vein by the improved disposable infusion needle and supplied physiological saline at the condition of ether inhala-tion anesthesia and once a day until to the thirteenth day,and then the times of draw blood and the number of survival rats only to calculate the success rate and survival rate of rats were record. Results In the 12 days,the tail vein blood of 24 SD rats were successfully collected. But a rat died of excessive ether inhalation anesthesia on the thirteenth day. The success rate was 99. 68% and the rat survival rate was 95. 83%. Conclusion The method that applying an improved disposable infusion needle and supplying physiological saline is safe and ef-fective,flexible and convenient,which is suitable for experimental study that needs to draw blood from caudal vein of the SD rat at the contin-uous time.
