To explore the relationship between serum total bile acid concentration and fetal prognosis in patients with intrahepatic cholestasis of pregnancy (ICP).A total of 131 ICP patients were divided into mild and severe ICP groups according to serum total bile acid concentration.And another 100 normal subjects during the same period were selected as control group.Their medical records and fetal prognoses were analyzed.The serum total bile acid,liver enzyme and lipid concentration of ICP patients were all significantly higher than those of the controls (P < 0.01).The fetal prognoses of ICP patients were significantly different with those of controls (P < 0.05).A high serum level of total bile acid of ICP patients may produce serious adverse effects on fetal prognosis.

[Objective]To explore the curative effect of the three diamen sional external fixation frame and limited internal fixation in treating the comminuted fracture of the shaft of humerus.[Method]Twenty-eight patients of the comminuted fracture of the shaft of humerus were treated from Jan 2000 to May 2006.According to the AO/ASIF,there were 5 cases of the B1 type,3 cases of the B2 type,9 cases of the B3 type,6 cases of the C1 type,4 cases of the C2 type,1 case of the C3 type.All of them were treated by the three diamensional external fixation frame and limited internal fixation of the screws or wires,and all of them were given the reasonable rehabilitation training at 3 day after the operation.The curative effect of the operation,the complications,the fracture healing and the function appraisal were analyzed.[Result]The 28 patients were followed-up for 10~15 months(average 13 months),27 cases had the frature healed and the healing rate was 96.4%.The healing period of the fracture lasted from 12 weeks to 33 weeks,average 19.5 weeks.Only 1 case was not healed.The functions of the shoulder and the elbow were normal,the excellent rate was 92.8%.[Conclusion]The three diamensional external fixation frame and limited internal fixation is a better method in treating the comminuted fracture of the shaft of humerus.It fits the rule of minimal-invasive-biology. The operation is simple,and the fixation is reliable,the function is satisfactory.

In surgery operations, wound should be cleaned with warm sterilized saline solution. In order to reach rapidly warming the washing solution from the room temperature during the surgery, we designed a thermostatic medical infusion pump. The present paper mainly presents researches on the two temperature control methods in the standby mode and in the flushing mode of the system. In the standby mode, the traditional proportional-integral-derivative (PID) control algorithm was adopted. In the flushing mode, dynamic characteristics of the system was changed in real time, which made the thermostatic control process more complex, and the fitted control function combined with the PID control algorithm was adopted in this mode. The temperature control parameters were adjusted in real time according to the initial temperature and the flow rate of the washing solution to obtain a constant temperature of the washing solution, no matter how the initial temperature and the flow rate are changed. The experiment results showed that this kind of control system performed well with a high accuracy.

Objective To compare the placement of peripherally inserted central catheters(PICC)by using vascular ultrasound guidance system and traditional method.Methods Totally 938 patients undergoing PICC were divided into the traditional method group and the vascular ultrasound system and microintroducer techniques group according to the puncture time.The differences in the one-attempt success rate and the overall success rate of the placement and the incidences of complications were compared between the two groups.Results The one-attempt success rate was 93.01% in the traditional method group and 98.76% in the vascular ultrasound system and microintroducer techniques group(P =0.005).The successful rate of PICC placement was 100%.The incidence of complication was 11.29% in the traditional method group and 2.47% in the vascular ultrasound system and microintroducer technique group(P =0.000).Conclusion The PICC placement using vascular ultrasound guidance system and microintroducer techniques can increase one-attempt success rate and decrease complications.

ObjectiveTo investigate the role of Nav1.7 in dorsal root ganglia (DRG) in a rat model of diabetic neuropathic pain (DNP).MethodsThirty-two female Wistar rats aged 3 months weighing 180-220 g were randomly divided into 4 groups ( n = 8 each):control group ( group C),sham operation group ( group S),DNP group and ProTx- Ⅱ (a selective Nav1.7 blocker) group (group E).Diabetes mellitus was induced by intraperitoneal streptozocin 65 mg/kg.Blood glucose level and mechanical paw withdrawal threshold (MWT)to von Froy filamentstimulation were measured 2 weeks later.DNP was confirmed by blood glucose level ≥ 16.0 mmol/L and MWT decreased by more than 50% of the baseline value.Intrathecal catheter was implanted at L5,6 interspace on day 10 after successful induction of DNP.On day 4 after placement of the intrathecal catheter,ProTx- Ⅱ 10 μg/kg was injected intrathecally in group E,while the equal volume of normal saline was given in groups DNP and S.MWT and never conduction velocity (NCV) were measured 1 h after intrathecal injection.The rats were then sacrificed and DRGs of the lumbar segment (L4-6) were removed for determination of Nav1.7 protein expression (by immuno-histochemistry and Western blot) and Nav1.7 mRNA expression (by RT-PCR).ResultsThe MWT and NCV were significantly lower and the Nav1.7 mRNA and protein expression was significantly higher in groups DNP and E than in group C.ProTx- Ⅱ significantly attenuated the diabetes-induced changes in MWT,but had no effect on NCV and Nav1.7 mRNA and protein expression.ConclusionNav1.7 in DRG is involved in the maintenance of DNP in rats.

Objective:To analyse the property of voltage-dependent potassium 〔K(v)〕 channel in healthy people′s peripheral lymphocyte so as to contribute the control for property alteration under some pathological condition,and to try to find the new subset of this channel.Methods:Patch-clamp whole cell recording technique was used.Results:In the recorded 39 cells,activated voltage of the channels was -40.3±2.5 Mv.No inactivation phenomenon appeared under repeated stimulation.The closing time of the channels was 116.3+8.2 ms under the repolarization,and the current could be inhibited by 10 mmol/L TEA.Conclusion:There might be only one type of K(v) channel in human peripheral blood lymphocytes,and its properties quite resumble the type of n K(v) channel in mice.
