In order to investigate the effects of verapamil on the proliferation of meningiomas cells in vitro and in vivo, the cultured meningiomas cells were cultured with verapamil at different concentrations for 24 h and the inhibitory effects of verapamil on cell proliferation were observed by MTT method. The meningiomas model was established by implanting the newly removed tumor fragments into the nude mice subcutaneously. The nude mice with tumors were divided into two groups: verapamil-treated group and control group. Tumor volumes were measured and after 12 weeks the tumors were taken out and examined histologically. The expression of proliferating cell nuclear antigen (PCNA) in the tumors was detected by using immunohistochemistry. It was found that verapamil could inhibit the growth of cultured meningiomas cells in a concentration-dependant manner. The inhibitory effect could be observed in the concentration of 1 micromol/L verapamil and the most obvious effects appeared in the concentration of 100 micromol/L. Tumor volume in the verapamiltreated group was obviously smaller than that in the control group (211.40+/-5.50 vs 163.94+/-3.62, P<0.01) and the expression of PCNA was also lower (1.52+/-0.24 vs 2.86+/-0.53, P<0.05). Tumor inhibition rate was about 22.45%. It was suggested that verapamil could inhibit the proliferation and growth of meningiomas cells in vitro and in vivo.

Objective To investigate the depressive disorders in patients with respiratory diseases and analyze the countermeasures against it to provide reference for improving clinical treatment compliance. Methods 80 cases was selected according to the screening and exclusion criteria from 262 patients with respiratory diseases from January, 2014 to December, 2015. Then divided them randomly into treatment group and control group. The SDS and SAS show no statistical signiifcance before treatment (P>0.05). The control group with clinical disease symptomatic and supportive treatment, the treatment group combined with anti-anxiety treatment on the basis of clinical symptomatic and supportive group. Then compare the SDS, SAS and dyspnea improvement between the two groups before and after treatment. Results The SDS and SAS scores showed no significant difference before treatment (P>0.05). While after treatment, the SDS and SAS scores in treatment group were signiifcantly lower, and lower than the control group, the difference was statistically signiifcant (P<0.05). The condition of dyspnea of the two groups show no difference before treatment (P>0.05). After treatment, the condition of dyspnea improved greater in treatment group than the control group, the difference was statistically signiifcant (P<0.05). Conclusions Because the respiratory disease of patients suffered leads to psychological burden, negative emotional depression anxiety appears not well with the clinical work, by using Deanxit improve patient confidence and compliance, there is a certain positive to improve the clinical symptoms with good clinical value.

BACKGROUND: By now, safety of collagenase application is still controvertible and some scholars believed that collagenase might induce the peripheral tissue injury. It attracts much attention in clinic that whether there is nerve injury induced by collagenase chemonucleolysis (CCN) around the injection sites.OBJECTIVE: To observe the effects of collagenase on spinal nerve conduction velocity (NCV) of rats detected with evoked potential method so as to probe into the safetyof collagenase application and further demonstrate the safety of percutaneous intervertebral disc CCN. DESIGN: Randomly grouping design, animal experiment.SETTING: Department of Interventional Radiology, Affiliated First Hospital of Sun Yat-sen University. MATERIALS: The experiment was conducted in the Basic Medical College of Sun Yat-son University from July to September 2002. A total of 57 male SD rats were randomly divided into normal group (n=9), acute sham-operation group (n=10), subacute sham-operation group (n=8), chronic sham-operation group (n=7), acute experimental model group (n=9), subacute experimental model group (n=7) and chronic experimental model group (n=7). METHODS: After being anaesthetized by intraperitoneal injection of continal (45 mg/kg) to separate and identify dorsal root ganglion (DRG),rats in the experimental group were locally dripped with 1 mL of collagenase (300 U/ML) and those in the sham operation group locally dripped with 1 mL of normal saline. Stimulating electrode was placed in the A point of sciatic nerve and recording electrode in the B point of ganglionic central process segment of DRG in L5 nerve root. Evoked potentials A and B were simulated to continuously record latency twice, and the average value was calculated; Distance between A and B were measured and recorded. NCV = distance between A and B / latency. Evoked potential of a segment ofnerve including DRG was measured in the acute group at one hour after administration, in the sub acute group at one week after administration and in the chronic group at one month after administration. MAIN OUTCOME MEASURES: NCV of each group. RESULTS: A total of 57 enrolled animals were involved in the analysis. NCV in normal group, acute experimental group, acute sham-operation group, subacute experimental group, subacute sham-operation group, chronic experimental group, chronic sham-operation group were (45.4±10.7), (43.4±5.9), (46.3±6.5), (52.4±10.4), (49.7±8.1), (46.7±11.0) and (44.6±6.5) m/s respectively. There were no remarkable differences in NCV among all the groups by using one-way analysis of variance (F=1.010,P=0.430); It was showed that there were no marked differences in NCV between each two groups by using multiple comparisons (P=0.336). CONCLUSION: Collagenase at the therapeutic concentration applied in clinical CCN has no remarkable effects on NCV of rat spinal nerve, and to a certain extent, percutaneous intervertebral disc CCN is relatively reliable.

Objective To observe the anatomy of the perforator flap of the posterolateral midforearm. Methods Lateral condyle of the humems wag taken as the observation mark on 30 specimens of adult upper limb perfused with red latex.The surgical magnifier Wag used to obse~e the origin,branches and distribution of the perforating branches of the posterolateral midforearm as well as alanagtomosis between perforating branches and peripheral vessels.Mimic operation WaS performed on the two sides of the fresh specimen.Results The perforating branches of the posterolateral midforearm originated from the radial musculoculancous branches of the posterior interosseous artery,the intermuscular branches of the radial artery and the direct periosteal branch of the radial artery had relatively stable location of piercing the deep fascia.Then,the perforating branches of the posterolateral midforearm pagsed through the deep fascia to the subcutaneous part among the spatium intermusculare of extensor digitorum and extensor carpi radialis brevis,supinator and abductor pollicis longus(within 12.5-15.8 cm below the lateral condyle of the humerus).Large number of small blood Vessels were also separated and closely aligned with the musculoculancous branches vascular,perineural and neural stem vascular chain of lateral branches of posterior antebrachial cutaneous nerve.Then,the vascular plexus was formed along the spatium intermusculare and lateral branches of posterior antebrachial cutaneous nerve longitudinal axis between extensor digitorum and extensor carpi radialis brevis. Conclusion The axial pattern flaps or cross-regional blood supply skin flap pedicled with the perforating branches of the posterolateral midforearm Can be formed to repair the soft tissue defect of tlle forearm and wrist.

Objective The clinical features of elderly patients with severe acute pancreatitis (SAP) were atypical and these patients were often misdiagnosed as having paralytic ileus. The clinical presentations of elderly patients with SAP whose first diagnosis as paralytic ileus were analyzed. Methods 18 patients of elderly SAP who were misdiagnosed as having paralytic ileus were included and the clinical data were compared with 58 elderly patients with SAP. Results Among the misdiagnosis group, the first symptom onset were fleus, abdominal distension, vomiting, constipation, abdominal pain, diarrhea for 5, 4, 3, 3, 2, 1 case, respectively. Among SAP group, the first symptoms onset were 2, 31, 9, 3, 11, 2 cases, respectively. For misdiagnosis group, 13 cases were correctly diagnosed by CT scan, 3 cases by ultrasound and 2 cases by serum amylase test. For SAP group, 32, 15, 11 cases were diagnosed by CT scan, ultrasound and serum amylase, respectively (P < 0.05). 4 and 13 patients died in misdiagnosis and SAP group, respectively; among these 13 patients, 10 were female and 3 were male. Conclusions The elderly patients with paralytic ileus should consider the possibility of SAP, and CT scan was valuable for correct diagnosis.

Objective To provide anatomical basis for lateral antebrachial neurocutaneous flap pedi-cled with inferior cubital artery perforator in repairing tissue defects around elbow joint. Methods Thirty embalmed upper limbs of adult cadavers perfused with red latex were used for this study, and followings were observed:①The course and distribution of lateral antebrachial cutaneous nerve; ②Anastomoses between inferior cubital artery and nutrient vessels of lateral antebrachial cutaneous nerve.
