Objective To study the changes of apoptosis in brain after traumatic injury(TBI)treated with exogenous vascular endothelial growth factor(VEGF)gene therapy in oder to find out the role of exogenous VEGF gene in protectiog brain tissue.Method The injurea cerebral cortex from the rat models of brain with traumatic injury was injected with adenovirus(adenovirus,Ad)as the carrier of VEGF-165 gene(Ad-VEGF-165 Gene).RT-PCR and Western blot were used to detect the expression of VEGF mRNA and VEGF protein in the brain 6 h,24 h,3 d,7 d and 14 d after injury,and apoptosis in the injured location of brain was also detected by TUNEL successively after Ad-VECF-165 gene therapy.Results With exogenous Ad-VEGF-165 applied to the locally injured brain tissue after injury,VEGF mRNA and VEGF protein showed consistent expression and their expressions were significantly higher than those in trauma group and vehicle control group.Compared with the trauma group.the apoptosis in the gene therapy group 24 h,3 d and 7 d after injury presented a.significant reduction,and had close relationship with VEGF.(Control group:4.17±0.73;TBI group,24 h:47.18±6.01,3 d:79.44±11.23;TBI+VEGF group.24 h:28.72±5.31,3 d:54.18±7.66;P＜0.05).Conclusions The exogenous VEGF gene therapy administered to have protective effects on the local brain tissue in rats with traumatic injury in a certain time.

Objective To explore the surgical indexes, therapeutic efficacy and prevention of complications in treatment of some blood diseases by splenectomy (including laparoscopic splenecto- my). Methods The clinical data of 27 patients with blood diseases receiving splenectomy in our hospi-tal were retrospectively analyzed. Results The effective rate of splenectomy was 100% in 4 cases of hereditary spherocytosis, 76.47% in 17 cases of ITP and low in 6 cases of Non-Hodgkin's lymphoma.The postoperative incidence of complications was 7.41% (2/27). Conclusion Splenectomy is of the first choice for treatment of hereditary spherocytosis. Meanwhile, it is effective for most of the patients with ITP. It is an important approach for comprehensive of malignant lymphoma. Proper choice of indications and perioperative management are helpful for decreasing incidence of postoperative complications.

Objective To investigate the changes of region cerebral homodynamic and cerebral vascular autoregulation in traumatic brain injury(TBI) by dynamic CT perfusion(CTP) imaging in rat.Methods Forty-five SD rats underwent CTP,including 10 control rats and 35 TBI rats,on 1,6,24 h,and day 3,7,14,21 after TBI.The region of interest(ROI) was located near traumatic area within 2 mm and mirror area of relative brain hemisphere.False color pictures and dynamic rCBF,rCBV,MTT and PS were obtained in different time.Pathological examination was also done.Results The rCBF,rCBV on 1 h after TBI was lower than that of control group,and significantly higher on 6-24 h after TBI.They reached the peak on day 3.PS had a similar change compared with rCBF,rCBV,but a longer duration.MTT showed to moderate changes except an isolated tide on 3 days after TBI.The rCBF on mirror area of relative brain hemisphere was almost stable except 3 days after TBI,which was lower than that of control group.Meanwhile,the rCBV on mirror area of relative brain hemisphere was normal.Conclusion CTP is an advanced technique to investigate the changes of region cerebral homodynamic and cerebral vascular autoregulation in TBI.The early hypoperfusion and next hyperperfusion around traumatic areas after TBI suggest that the dysfunction of cerebral vascular autoregulation should be committed to the change of homodynamic in TBI.

Objective:To select proper macroporous resins for enrichment triptolide.Methods:Experiments were performed to adsorb triptolide by three types macroporous resins.Then the triptolide and solide content on the columns were eluated with 95% alcohol and determined by HPLC.Results:Results showed that the macroporous of type D101 is the best choice for enrichment of triptolide.Conclusion:the macroporous of type D101 can be used for triptolide enrichment.

[Objective] To explore the clinical characteristics and pathogenic mechanism of sensory ataxia form of GBS.[Methods] To Summarize clinica1 data of 19 cases with sensory ataxia form of GBS.[Result] The main clinical manifestations were sensory ataxia.The disease relieved and recurred easily and had long course.The protein in CSF increased significantly.Pathological feature was same with general CIDP.Treatment of glucocortieoid was satisfied.[Conclusions] Sensory ataxia form of GBS was one sub-type of CIDP.Pathogenic mechanism was perhaps that immunoreaction attacked proproioceptive sense fibre of radix dorsalis.

Objective To explore the influence of no drainage on pelvic lymphocyst following laparoscopic radical hysterectomy and pelvic lymphadenectomy . Methods A total of 105 patients with cervical cancer undergoing laparoscopic radical hysterectomy and pelvic lymphadenectomy in this hospital from January 2012 to February 2016 were divided into either non-drainage group (50 cases) or drainage group (55 cases) according to whether the pelvic drainage tube was placed after surgery .Comparative analyses on the incidence of postoperative complications such as pelvic lymphocyst were made between the two groups . Results No significant difference in lymphocyst rate was found between the two groups [27.3%(15/55) vs.24.0%(12/50), χ2 =0.147, P=0.702].The incidence of pelvic infection was lower in the non-drainage group (2.0%, 1/50) than that in the drainage group (14.5%, 8/55), but the difference was not statistically significant (χ2 =3.781, P=0.052).Other postoperative complications including urinary retention , urinary fistula, and deep venous thrombosis of lower limb had no statistical differences between the two groups (P>0.05). Conclusions Drainage after radical hysterectomy and pelvic lymphadenectomy for cervical cancer does not make a difference to the incidence of lymphocyst .Non-drainaging doesn ’ t increase the risk of infection .

Objective: To assess the autonomic nervous impairm ent in chronic renal failure and its related factors. Methods: F orty adults were randomly selected including in-patients in the nephrology ward and healthy subjects for routine medical examination. The subjects were classifi ed into 4 groups: normal subjects(NS)，normal renal function，nitremia， uremic patients. The time domain measurements of heart rate variability(HRV) and ambula tory blood pressure were analyzed simultaneously . Results: (1) There were significant differences as compared with normal subjects in the time domain measurements of HRV in uremic group. It decreased significantly when the patient was defined as end stage chronic renal failure. There were no significan t differences between NS，normal renal function group and nitremic group. (2) Ti me domain measurements of HRV was significantly lower(P<0.05) in uremia with renal hypertension than in uremia with normal blood pressure. Conclusio n: (1) Patients with chronic renal failure(HRV) have their cardiac auton omic nervous system impaired conspicuously in the course of uremia. (2) There is a positive correlation between cardiac autonomic nervous system impairment in p atients with CRF and renal function levels. Uremia itself is an independent fact or for the impairment of cardiac autonomic nervous system. (3) Renal hypertensio n with uremia may intensify the impairment of cardiac autonomic nervous system of the patients.
