The experiment was performed at Basic Medical College and First Affiliated Hospital, Zhengzhou University from September 2004 to December 2005. Totally 60 Kunming mice were divided into 5 groups randomly: ①blank control group (n =15) and simple radiation group (n =15). The mice were given 0.2 mL sterile saline by intraperitoneal injection. ②antineoplastic polypeptide from Buthus Martensii Venom (APBMV) group (n =10) and APBMV plus radiation group (n =10) received 0.2 mL APBMV according to prepared concentration by intraperitoneal injection. ③Katsutoxin extract Ⅲ plus radiation group (n =10) received 0.2 mL katsutoxin extract Ⅲ by intraperitoneal injection every other 5.5 hours for 7 days. After 24 hours from the last injection, the mice were endured 60Co g ray radiation (80 cm, 7.5 Gy irradiation dose, 0.27 Gy/min dose rate). Then katsutoxin extract Ⅲ was given same as above for 7 days. Then bone marrow was extracted to be cultured to colony-forming unit-granulocyte and monocyte (CFU-GM). The findings showed that colony amount of APBMV plus radiation group and katsutoxin extract Ⅲ plus radiation group was obviously more than that of simple radiation group [(32?5),(27?3),(2?1)pieces/well,P

Objective To explore the therapeutic effect,advantages and shortcomings of pleural effusion controlled by interrupted drainage via central venous catheter.Methods The research group had 52 cases with pleural effusion controHed by interrupted drainage via central venous catheter,and the control group had 50 cases with pleural effusion controlled by conventional pleuracentesis.Pleural effusion disappearing time,average hospitalization time,pleuracentesis frequency,related therapy expenses and complications of two groups were observed and compared.Results The pleuracentesis frequency,pleural effusion disappearing time,average hospitalization time,related therapy expenses and per capita incidence of complications of the research group were(1.06±1.30)times,(4.31±2.20)days,(9.87±2.30)days,(264.77±37.20)yuan and 9.62%and in the control group were(4.20±2.60)times,(9.92±3.70)days,(15.08±5.80)days,(487.62±55.56)yuan and 38.00%.The differences between two groups were particularly remarkable.Conclusion The method of pleural effusion controlled by interruptod drainage via central venous catheter is safe,eonvenient,economical and microtraumatic,and it is worth using more widely.

Objective To study related factors of the duration of untreated psychosis (DUP) in Tibetan patients with schizophrenia in Qinghai Province. Methods The related factors on DUP were investigated in totally 188 Tibetan pa?tients with schizophrenia using questionnaires of mental health services and symptom onset for schizophrenia. All the Ti?betan patients were provided with the National Continuing Management and Intervention Program for Psychoses (686 Pro?gram). Results The median (low quartile, upper quartile) of DUP in Tibetan patients with schizophrenia was 375 days (4 days, 1661 days). The patients were divided into short DUP group (DUP≤375days, 90 patients) and long DUP group (DUP>375 days, 98 patients). There were significant differences in mode of onset,marital status, educational level, family type, place of residence between short DUP group and long DUP group (P<0.05). Logistic regression analysis found that lack of family structure (OR=2.340, 95%CI:1.130~4.847, P=0.022), chronic onset (OR=2.136, 95%CI:1.172~3.891, P=0.013) and living in pastoral areas (OR=2.239, 95%CI:1.097~4.571, P=0.027) were risk factors of DUP. Conclusion Ti?betan patients with schizophrenia have a longer DUP and related risk factories of DUP are lack of family structure, chron?ic onset and living in pastoral areas.

Objective To explore the executive function in patients with mild traumatic brain injury (mTBI). Methods The evaluation of executive function was conducted in 63 mTBI patients in 1 week, 1, 3 and 6 month after injury and 60 health controls. The executive function was evaluated using Trail Making Test (TMTA), Hopkins Verbal Learning Test-revised (HVLT-R), Brief Visuospatial Memory Test-revised (BVMT-R), Stroop Color Word Tes and Con-tinuous Performance Test (CPT). Results There were significant differences between mTBI patients and controls in TM-TA, HVLT-R, BVMT-R, Stroop Color Word Test and CPT a week following TBI (P<0.05). There were a significant in-crease in scores of TMTA and a significant decrease in HVLT-R, BVMT-R, stroop and CPT-IP at 1, 3 and 6 month compared with 1 week following TBI (P<0.05). There were a significant decrease in TMTA and a significant increase in BVMT-R and stroop 1 month compared with 1 week following TBI (P<0.05). There were a significant increase in stroop, BVMT-R and CPT-IP at 3 month compared with 1 month following TBI (P<0.05). There was a significant increase in stroop and CPT-IP at 6 month compared with 3 month following TBI (P<0.05). Conclusions Patients with mTBI have executive function impairment. The recovery times of different executive function are different in patients with mTBI.

Objective:To investigate clinical characteristics of bullous pemphigoid (BP) developing after the treatment with dipeptidyl peptidase-Ⅳ inhibitors (DPP4i) in patients with diabetes mellitus.Methods:A total of 116 inpatients with BP complicated by diabetes mellitus were collected from the Seventh People′s Hospital of Shenyang between January 2014 and December 2020, and divided into 2 groups: DPP4i-BP group treated with DPP4i before the onset of BP, and general BP group receiving no treatment with DPP4i. General clinical data, skin lesion area, laboratory indicators, treatment regimens, and prognosis were analyzed and compared between the above 2 groups, the time interval from the administration of DPP4i to the diagnosis of BP was recorded in the DPP4i-BP group. One-way analysis of variance was used to compare measurement data among multiple groups, two-independent-sample t test was used for comparisons between two groups, and paired t-test for intra-group comparisons before and after treatment; chi-square test was used to compare enumeration data between groups. Results:There were 32 patients aged 77.17 ± 15.32 years in the DPP4i-BP group, with a male-to-female ratio being 15∶17; there were 84 patients aged 76.65 ± 19.32 years in the general BP group, with a male-to-female ratio being 43∶41. The time interval from the administration of DPP4i to the diagnosis of BP was 14.61 ± 3.93 months in the DPP4i-BP group. The time interval for vildagliptin was the shortest (5.42 ± 2.84 months) , and there was a significant difference in the time interval among vildagliptin, sitagliptin, linagliptin and saxagliptin ( F= 8.93, P < 0.001) . The proportion of patients with severe BP was significantly higher in the DPP4i-BP group (16 cases, 50%) than in the general BP group (25 cases, 29.76%; Z= 2.63, P= 0.008) . There was no significant difference in the positivity rate of anti-BP180 antibody between the two groups ( χ2= 0.03, P= 0.870) . However, the level of anti-BP180 antibody was significantly higher in the DPP4i-BP group than in the general BP group before and after treatment ( P= 0.015, < 0.001, respectively) , and the decrease in the level of anti-BP180 antibody was significantly less in the DPP4i-BP group than in the general BP group after treatment ( t= 5.11, P < 0.001) . There was no significant difference in the average effective dose of glucocorticoids required to control the disease between the two groups ( t= 1.00, P= 0.322) . However, the DPP4i-BP group showed a significant increase in the average time required to control the disease and in the proportion of patients requiring combined treatment with immunosuppressants or other drugs compared with the general BP group ( t= 6.72, 10.05, P < 0.001,= 0.002, respectively) . Within 6 months after the start of systemic treatment, the recurrence rate was significantly higher in the general BP group (17 cases, 27.86%) than in the DPP4i-BP group (2 cases, 7.69%; χ2= 4.35, P= 0.037) ; at 6 months, the average dose of glucocorticoids was also significantly higher in the general BP group than in the DPP4i-BP group ( t= 7.04, P < 0.001) . Conclusions:Among the DPP4i hypoglycemic drugs, vildagliptin was the most common drug administrated by patients before the onset of BP, with the shortest interval from the administration to the onset of BP. DPP4i-BP may be difficult to control at the early stage, but the prognosis is good.

OBJECTIVETo compare the ettect and side-ettect of fluoxetine and combination of fluoxetine and Chinese or Tibetan medicine in treating senile depression in plateau district. Methods Ninety patients with diagnosis of senile depression conformed to CCMD-3 standard, in plateau district of 2260 - 3200 m altitude were randomly divided into three groups and treated with fluoxetine (group A), fluoxetine plus Sanpu Xinnao Xin granule (group B) and fluoxetine plus Xiaoyao pill (group C), respectively, 30 cases in each group. Therapeutic effects were evaluated with Hamilton' s depressive scale (HAMD) and treatment emergent symptom scale (TESS) after 6 weeks treatment.

RESULTSThere was no significant difference in the therapeutic effects between the three groups. The adverse reaction in Group B and C was less than that in Group A (P<0.01). Conclusion Sanpu Xinnao Xin granule and Xiaoyao pill can raise the tolerance of patients with senile depression in plateau area against the adverse reaction of fluoxetine.
