In the present study, we observed the effects of cholinergic enhancement by pyridostigmine (PD), a cholinesterases inhibitor, on GH release in both normal (n = 13) and GH deficient children and adolescents (n = 8). Responses of GH to insulin hypoglycemia were also observed. In the normal subjects, PD-induced serum GH peak levels were significantly higher than that induced by insulin (P

Objective To study the surgical treatment of major blood vessels invaded by tumors in order to raise the resection rate and postoperative survival rate. Methods Clinical data were analyzed on 26 patients undergoing (resection) of tumors along with reconstruction of major blood vessels from October 1998 to February 2004. Results Tweety-three cases were followed up for 2～65 months with median 42.8 months. Doppler ultrosonography and CTA examination were performed respectively during the follow-up process.In 5 patients with carcinoma of the head of pancreas who had inferior vein cava replaced and in 1 patient with cholangiocarcinoma who had portal vein replaced,3 were complicated with carcinoma embolism formation at 3,12 and 15 months respectively after surgery,(postoperative) graft patency was 50%;all of the 6 patients had recurrence of the tumor at 3,6,8,12,24 and 31 months respectively after surgery.Seven patients with tumor in pelvic cavity or in posterior space of peritoneum were followed up for about 2 years,1 of them had tumor recurrence ,but the graft kept patent,2 patients with sarcoma in the limbs were followed up for 1 year without tumor recurrence or vessel obstruction.Eleven patients with tumors in the neck were followed up for 3 months to 5 years without tumor recurrence or vessel obstruction. Conclusions (Combination) of resection of neoplasm and reconstruction of major blood vessels is safe,effective and practical method for patients with major wessels invaded by tumor.

ObjectiveTo explore the action of the psychointervension for older hypertensives in community.Methods50 older hypertensives were divided into the experimental group and the control group (with 25 cases in each group),the former received psychointervension combined body therapy and the later only received body therapy. A half of a year experiment period was made. Differences between two groups in blood pressure and SCL-90 before and after the experiment were compared and evaluated.ResultsThe mentation of older hypertensives is worse than the normal. There are distinct differences between two groups in the improvement of mentation and the stability of blood pressure (P<0.01). Conclusions It is an active effect to strengthen psychointervension for therapy of older hypertensives in community.

To understand the adverse drug reaction (ADR) induced by Mailuoning injection. 162 ADRs due to the drug were retrieved from national medical journals of 1988-2007 for statistics. It was shown that there was no relationship between ADR and dosage, but ADR appeared mostly in middle-aged and old groups, and more in male than in female. The occurrence of ADR was commonly within 30 min after injection. It involved injuries of various systems and organs. As for the 123 cases of allergy, 38 were anaphylactic shock (accounting for 23.46%), two people died. ADR characterized by immediate type on initial use and tachy type. It should be paid more attention to the Mailuoning injection for the immediate hypersensitivity reaction (such as anaphylactic shock).

Background Oxidative stress-induced apoptosis of human lens epithelial cells (LECs) is associated with c-Jun N terminal kinase (JNK) pathway.Quercetin possesses the antioxidation by inhibiting the JNK pathway.However,whether quercetin can protect LECs from the oxygen-induced damage is still not proved.Objective This study attempted to invatigate the effects and its mechanism of quercetin against hyperbaric oxygeninduced LECs apoptosis. Methods Human LECs line SRA01/04 was cultivated and passaged in MEM medium containing 10％ fetal bovine serum and 0.5％ non-essential amino acids for 2 hours,with or without 20 μmol/LSP600125 or 1 μmol/L quercetin prior to exposure to hyperbaric oxygen.Each exposure session remained 6 hours in 99％ O2 and 1％CO2 with a pressure chamber at 588 kPa.The viability of human LECs was detected by MTT.Cell apoptosis was assessed by flow cytometer using Annexin V-FITC apoptosis detection.The expression of JNK/p-JNK,c-Jun/p-c-Jun,caspase 3 and caspase 9 were detected by Western blot. Results LECs viability (A570 ) was 0.835 ±0.082,0.450±0.083,0.654±0.079,0.649±0.090 respectively in the blank control group,hyperbaric oxygen exposed group,hyperbaric oxygen+SP600125 group and hyperbaric oxygen+quercetin group.The A570 in the hyperbaric oxygen exposed group was significantly lower than the blank control group ( P =0.000),but those in hyperbaric oxygen + SP600125 group and hyperbaric oxygen+quercetin group were significantly higher than the hyperbaric oxygen exposed group ( P =0.003,0.002 ).The numbers of apoptosis cells were 3.17 ±0.74,19.77 ± 1.44,8.45 ±0.93,7.79 ±0.78 respectively in the blank control group,hyperbaric oxygen exposed group,hyperbaric oxygen+SP600125 group and hyperbaric oxygen+quercetin group.Apoptotic LECs were significantly increased in the hyperbaric oxygen exposed group compared with the blank control group ( P=0.000),but those in the hyperbaric oxygen+SP600125 group and hyperbaric oxygen+quercetin group were significantly reduced in comparison with hyperbaric oxygen exposed group (both P=0.000).In additional,expressions of p-JNK,p-c-Jun,caspase 3 and caspase 9 proteins in the cells were elevated in the hyperbaric oxygen exposed group compared with the blank control group (all P =0.000 ),however,those in the hyperbaric oxygen + SP600125 group and hyperbaric oxygen + quercetin group were declined when compared with the hyperbaric oxygen exposed group( all P＜0.05 ). Conclusions JNK pathway is involved in the apoptotic procedure of human LECs induced by oxygen stress.SP600125 and certain concentration of quercetin can interdict the JNK signal pathway and endogenous apoptosis of LECs and further alleviate hyperbaric oxygen-induced damage of LECs.

?AlM:To compare the anti-inflammatory effects with lotrprednol-tobramycin and tobramysin-dexamethasone eyedrops after phacoemulsification combined intraocular lens implantation.
? METHODS: ln this prospective, comparative, randomized controlled trial, patients with senile cataract who underwent phacoemulsification combined intraocular lens implantation in our hospital from January 2014 to October 2014 were enrolled, which were randomly divided into two groups. Patients were given lotrprednol -tobramycin ( LE/T group ) and dexamethasone-tobramysin ( D/T group ) eyedrops respectively. Preoperative and postoperative intraocular pressure, malnutrition inflammation score, bruggrmann comfort scale were observed.
?RESULTS:A total of 143 eyes of 143 cases were enrolled, of them 81 cases were in the LE/T group and 62 in the D/T group. There were no statistically significant differences between the two groups in malnutrition inflammation score and bruggrmann comfort scale. The average intraocular pressure was 16. 5±3. 1mmHg in D/T group after 14d postoperation, which was obviously higher than LE/T group ( 14. 7± 3. 7mmHg, P = 0. 004 ). After 14d postoperation, the intraocular pressure of 2 cases were > 21mmHg, which were back to normal after drug withdrawal.
? CONCLUSlON: The anti - inflammatory effects lotrprednol-tobramycin and tobramysin-dexamethasone eyedrops are similar after phacoemulsification. However, lotrprednol-tobramycin has little influence in intraocular pressure, and more safety.

?AIM:To compare the changes of the contrast sensitivity after LASIK with femtosecond laser and microkeratome and to explore the influence of different methods making corneal flap on visual quality.? METHODS: There were 212 eyes in 106 myopes underwent excimer operation . According to the different methods of operation, they were divided into two groups:microkeratome group ( SBK group ) and femtosecond laser group ( FS group) . FS group: a total of 112 eyes in 56 patients received LASIK with femtosecond laser. SBK group: a total of 100 eyes in 50 patients received LASIK with microkeratome. Contrast sensitivity was detected preoperatively, and 1wk, 3mo postoperatively and compared between the two groups.? RESULTS: At 1wk after operation, the contrast sensitivity under photopic environment decreased in the two groups, compared with those before operation ( P<0. 05). The differences of contrast sensitivity before and 3mo after operation were not significant (P>0. 05). No statistical significant difference was found in contrast sensitivity under photopic environment at 1wk, 3mo between the two groups ( P>0. 05 ). At 1wk after the operation, the contrast sensitivity under scotopic environment decreased in both groups compared with those before operation ( P< 0. 05 ). In SBK group, it decreased more than in FS group (P<0. 05). After 3mo, the decline of 14. 2c/d spatial frequency contrast sensitivity under scotopic environment in the SBK group was more than other frequency. No statistical significant difference was found in the rest frequency contrast sensitivity under scotopic environment before and after operation (P>0. 05). After 1wk, contrast sensitivity with glare stimulation in both groups decreased, compared with those before operation ( P< 0. 05 ), while in SBK group, it decreased more than in FS group (P<0. 05). After 3mo, except that the decline of 14. 2c/d spatial frequency contrast sensitivity with glare stimulation in the SBK group was significant compared with those before operation, the contrast sensitivity under glare stimulation in both groups had no significant differences compared with before operation(P>0. 05).?CONCLUSION:LASIK with femtosecond laser can get a better visual quality than LASIK with microkeratome.
