Therapeutic effect of short-term administration of IFN-a on non-small cell lung cancer ( NSCLC) was observed . Seventy-two cases of NSCLC patients were randomized into two equal groups. The control and the IFN-a group received the same chemotherapeutic treatments while the latter group were also intramuscularly injected with IFN-? 1 ? 10~(6)U/day for 20 days. Treatment effect rate, the number of white blood cells, the growth of carcinoma cells and the in-terclude time of chemotherapy were studied. Statistically significant difference with each index was observed between the two groups. The results indicated that the short-term administration of IFN-? during chemotherapeutic suppression inhibited tumor growth and made a shortened chemotherapeutic treatment interval acceptable. All showed that administration of IFN-? was feasible and effective in NSCLC chemotherapeutic treatment.

Objective:To investigate the reasonable approach and surgical indication for acute necrotizing pancreatitis(ANP)by analyzing the factors that affecting the mortality of ANP.Methods:One hundred and twelve patients with ANP were retrospectively divided into two groups-the dead and the survivors.Some parameters were analyzed statistically to reveal what's the reason for death.Results:The average age,sex ratio and onset of illness were similar between two groups.And the ratio of early shock,early adult respiratory distress syndrome (ARDS),high temperature,leukocytosis and high blood glucose between two groups were also similar between two groups(P＞0.05,respectively).The important factors that affecting the mortality were:①severity of pancreatic necrosis,②improper surgical approach,③incorrect surgical indication.Conclusion:The patiets with mild or moderate ANP should mainly receive conservative treatment for 48～72 hours.The early shock and ARDS should be redressed before surgical intervention.If the operation is unavoidable,the swelling pancreas should be dissected fully,which will provide sufficient drainage after operation,and duodenostomy should be performed during operation.

Objective To observe the efficacy of Chinese herbal fumigant sitz bath for different exposure durations on patients for the complicatiors after mixed hemorrhoidectomy.Methods One hundred and twenty patients with mixed hemorrhoidectomy were randomized into four groups(2 treatment groups and 2 control groups) with 30 cases in each group.The treatment groups were treated with the Chinese Herbal fumigant sitz bath for 10 minutes and 15 minutes respectively;while the control groups were treated with the hemorrhoids lotion for 10 minutes and 15 minutes respectively.The severity of pain,edema,bleeding,constipation and urinary disturbance were scored on the second,seventh and fourteenth days after treatment.Data were analyzed statistically.Results Chinese herbal fumigant Sitz baths for 10 minutes could significantly reduce postoperative pain,edema and bleeding symptoms[(1.72±1.23) points,(0.72±1.25) points,(0.91±1.37) points,respectively,P ＜0.05],followed sequentially by groups of Chinese herbal fumigant Sitz baths for 15 minutes [(1.79±1.21)points,(0.89±1.28) points,(1.03±1.24) points]; The hemorrhoids lotion for 10 minutes ((1.86±1.25) points,(1.14±1.47) points,(1.49±1.56)) and 15 minutes[(2.03±1.48) points,(1.05±1.29) points,(1.39±1.47) points,respectively,P ＜ 0.05]With the successful cases of 27,21,18,and 6 in the groups,respectively.Though the overall response rates of for the groups of 10 min's treatment,15min's treatment and 10 min's control were not significantly different between each other(P =0.0634,P =0.2560),they showed a superior efficacy in the overall response rate to the 15 min's control group(P =0.0064,P =0.0365,P =0.0089),respectively.Conclusion Chinese herbal fumigant Sitz baths for 10minutes have a success rate of 100％ on alleviating complications after mixed hemorrhoidectomy.It has a prominent efficacy on reducing postoperative edema and bleeding symptoms than other treatments studied in this program.

Objective To investigate the role of substance P (SP) and its neurokinin-1 receptor (NK-1R) in the pathophysiologic process of Crohn′s disease. Methods In 23 surgical patients of Crohn′s disease and 24 healthy controls, reverse transcription polymerase chain reaction (RT-PCR) was used to determine the mRNA expression of NK-1R, Western blot analysis was used to determine NK-1R protein expression levels, and immunohistochemistry was used to localize expression of NK-1R. Results Compared with normal gut NK-1R mRNA and NK-1R protein in Crohn′s disease were overexpressed. In Crohn′s disease moderate to strong intestinal NK-1R immunoreactivity was found in the lamina propria mononuclear cells, lymphoid follicles, and the surface and crypt epithelium, lymphoid follicles, submucosal vessels, smooth muscle and myoenteric plexus neurones. Conclusions In cases of Crohn′s disease, overexpression of NK-1R may disturb neuropeptides loop balance, and may be involved in the pathophysiological change in this disease.

AIM: To investigate the expression of neurok inin-2 receptor (NK-2R) in normal pancreas and chronic pancreatitis (CP) tissues. The relation of expres sion of NK-2R with pain in CP was also evaluated. METHODS: CP tis sues were ob tained from 18 men and 7 women undergoing pancreatic head resection as a result of CP. Normal human pancreatic tissues were obtained from 20 patients (11 males/ 9 females). Real-time quantitative reverse transcription polymerase chain reacti on was used to determine the mRNA expression of NK-2R, Western blot analysis was used to determine its protein expression level, and immunohistochemistry was us ed to localize expression site of NK-2R protein. NK-2R mRNA level and pain were also analysed whether correlation exists. RESULTS: NK-2R mRNA and p rotein level were enhanced expressed in CP tissue samples compared with normal pancreas. Ove rexpression of NK-2R was related to the intensity ( r=0 59, P

Objective To investigate the effects of exendin-4 (exenatide) on insulin sensitivity and adipocytokine in high-fat-fed rats. Methods Rats were divided randomly into normal-chow group (NC), high-fat group (HF) and high-fat+exendin treated group (HE). HE rats were given exenatide (2 μg/kg) twice daily for 6 wk. The insulin sensitivity was evaluated by intravenous insulin tolerance test (IVITT). Insulin-stimulated changes in insulin signal transduction, visfatin and adiponectin mRNA expressions as well as their plasma levels were also observed in these rats. Results Plasma free fatty acids (FFA), triglyceride (TG), total cholesterol (TC) levels were significantly reduced after exenatide treatment (in HE rats all P<0.01). And IVITT parameters were also improved in these rats. Insulin-stimulated IRS-1 tyrosine phosphorylation was slightly increased in exenatide-treated rats as compared with HF rats (P<0.05). In addition,plasma visfatin level was significantly reduced in HF and HE groups as compared with controls (P<0.05 and P<0.01). The adiponectin mRNA expression in adipose tissues and circulating adiponectin level were significantly elevated in exenatide-treated rats as compared with untreated rats and controls (P<0.01). Conclusions Chronic exenatide treatment improves insulin resistance in high-fat-fed rats, and the changes of IRS-1 tyrosine phosphorylation and adiponectin may be related to the role of exenatide in elevating insulin sensitivity

Objective:To investigate the safety, efficacy and survival of brentuximab vedotin (BV) monotherapy and BV combined with chemotherapy for relapsed or refractory lymphoma.Methods:A total of 47 patients with relapsed or refractory Hodgkin's lymphoma (HL) in First Medical Center of PLA general Hospital and Fourth Medical Center of PLA General Hospital from October 2011 to December 2018 were admitted, including 35 cases (BV monotherapy group) and 12 cases (BV combined with chemotherapy group); there were 8 cases of relapsed or refractory anaplastic large cell lymphoma (ALCL), 4 cases in BV monotherapy group and 4 cases in BV combined with chemotherapy group. The safety, clinical efficacy and survival of two neoplasms in different groups were compared.Results:For relapsed or refractory HL, the objective remission rate (ORR) and complete remission rate (CRR) was 67.7% (21/31) and 16.1% (5/31), and the median progressive-free survival (PFS) time was 3.5 months (1.5-24.0 months) in BV monotherapy group; ORR and CRR was 81.8% (9/11) and 27.3% (3/11), and median PFS time was 5.5 months (2.0 - 24.0 months) in BV combined with chemotherapy group; there was no statistical difference in ORR and CRR between the both groups (χ 2 = 0.788, P = 0.375; χ 2 = 0.654, P = 0.419). There were 4 cases in BV monotherapy group for ALCL, of which 3 could be evaluated for efficacy, including 1 case of complete remission (CR) and 1 case of partial remission (PR); there were 4 cases in BV combined with chemotherapy group for ALCL, of which 4 could be evaluated for efficacy, including 2 cases of CR and 2 cases of PR. The common adverse events in BV monotherapy group were anemia, leukopenia, thrombocytopenia, fever, elevated transaminase, fatigue, nausea, peripheral neuritis and cough. Grade ≥3 adverse events were mainly anemia, thrombocytopenia and leukopenia. The common adverse events of BV combined with chemotherapy group were similar to those of BV monotherapy group, and there were significant differences in bone marrow suppression (thrombocytopenia, leukopenia) between the two groups (all P < 0.05). Conclusions:The clinical efficacy of BV combined with chemotherapy is better than that of BV monotherapy in treatment of relapsed or refractory lymphoma, and the survival time is prolonged. The adverse reaction of BV combined with chemotherapy is mainly manifested in bone marrow suppression, and the safety and tolerability of patients are acceptable.
