Objective:To study the comparison of advantages of 3D and 2D laparoscope applied in clinical surgery.Methods: 42 cases were received retrospective analysis using 3D and 2D laparoscopic technology to complete abdominal surgery and were divided into 3D group and 2D group according to the methods of surgery. We observed the indexes for operation time, intraoperative blood loss, postoperative exhaust, catheter indwelling time, placement time of abdominal cavity drainage tube and postoperative hospitalization days, etc.Results: The two groups of patients completed smoothly laparoscopic surgery. There was no significant difference between 3D and 2D laparoscopic monitoring on indexes in the postoperative exhaust, catheter indwelling time, placement time of abdominal cavity drainage tube and postoperative hospitalization days. But the difference was statistically more significant in the operation time and intraoperative blood loss in 3D than that in 2D group (t=0.358,t=2.455;P<0.05).Conclusion:3D high definition amplification of three-dimensional surgical field similar with the traditional laparotomy is the future trend in the development of minimally invasive surgery. Compared with 2D, 3D technology can improve the overall level of the operation, with the features of easier and faster operation, smaller wound, quicker recovery, less postoperative complications, etc.

Objective:To study the trace injection pump in the application of the common problems and treatment measures.Methods: 246 cases of general surgery patients were used trace injection pump problems for retrospective analysis, in order to propose the improvements about engineering and management.Results: The incidence rate of non-standard operation procedures or the incidents are 6.1%, injection pump failure and infusion speed is 2.03%, mismatched injection pump attachments is 1.22% and phlebophlogosis is 0.41%. The non-standard operation procedures and imperfect trace injection pump management are the major problems. Therefore, some solutions are proposed, which includes strengthening technical training for medical staff, standard operation procedures, regular quality monitoring and healthy education to the patients.Conclusion: The operation procedures of trace injection pump should be standard and programmatic. It is of great significance to clinical application of the trace injection pump and to work properly by strengthening operation personnel quality, dealing with problems timely and correctly.

Objective To evaluate the therapeutic methods and the key points in the management of delayed complications of bile duct stenosis after iatrogenic bile duct injuries.Methods Five patients with bile duct injuries developed delayed complications of bile duct stenosis after cholecystectomy were retrospectively studied.All clinical information were derived from the medical data of these 5 patients treated in our department from June 2002 to July 2006.Results Of the 5 patients with delayed complications of iatrogenic bile duct injuries,2 patients developed common bile duct occlusion,2 patients developed hilar bile duct stenosis,and 1 patient developed anastomotic stenosis after cholangiojejunostomy.Bile duct injuries occurred in 3 patients after laparoscopic cholecystectomy,and in another 2 patients after mini-laparotomy-cholecystectomy.The locations of the bile duct injuries,according to Strasberg classification,were type E1 (n=1),type E2 (n=1),type E3,(n=1),and type E5 (n=2).All 5 patients received PTCD initially to relieve obstructive jaundice and then they received surgical exploration and biliary reconstruction.These patients received cholangioplasty at the porta hepatis,and hepaticojejunostomy using a Roux-en-Y anastomosis.Two patients received Roux-en-Y anastomosis of the common hepatic duct to the jejunum.All these patients had good recovery and were discharged well postoperatively.All patients had been followed-up for 7 years or more,with no evidence of obstructive jaundice or biliary tract infection.Conclusions For patients who present with delayed complications of bile duct stenosis after iatrogenic bile duct injuries,primary PTCD is carried out to relieve jaundice and to control infection.Meticulous dissection of the porta hepatis,reliable anastomosis of the proximal healthy bile duct tissues to a jejunal loop,and adequate size of anastomosis guarantee success of surgery.

Objective To explore the effectiveness of 125I seed implantation for gastric cancer and to determine whether the therapy could increase the survival rate.Methods Seventy-six gastric cancer patients in stage Ⅱ or Ⅲ were involved and randomly divided into treatment group (n =42) and control group (n =34)by simple random sampling method.The patients in the control group underwent D2 or D3 surgery and the patients in treatment group underwent D2 or D3 surgery plus interstitial implantation of 125I seeds.All patients signed the informed consents.Treatment results were evaluated as CR,PR,NC and PD.CR and PR were considered as effective and the effective rate was calculated.All patients were followed up and the three-or five-year survival rate was calculated,the complications were examined.x2 test was used to compare the significant difference between the two groups.Results The total effective rate in control group was 50.00％ (17/34),lower than that of treatment group (73.81％,31/42; x2 =4.578,P＜0.05).In the treatment group,the three-year and five-year survival rates were 61.90％(26/42) and 42.86％(18/42) respectively,and the corresponding rates in the control group were 11.76％(4/34) and 0(0/34) respectively (x2=19.771,19.094,both P＜0.001).Both of the two groups had few severe side effects.Conclusion Radical surgery plus 1~Iseed implantation is effective and safe for the treatment of stage Ⅱ or Ⅲ gastric cancer and can further improvelong-term survival.

Objective:To observe the clinical efficacy of Governor Vessel-unblocking and brain-refreshing scalp acupuncture for cerebral palsy (CP) complicated with intellectual disabilities. Methods:A total of 300 CP cases aged between 1 and 5 years were randomly allocated into a treatment group (n=150) and a control group (n=150). Patients in the treatment group were treated with Governor Vessel-unblocking and brain- refreshing scalp acupuncture combined with rehabilitation training, whereas patients in the control group received rehabilitation training alone. The Beijing Gesell developmental (Gesell) scale and gross motor function measure (GMFM) scale were used to assess the motor and intellectual development before and 3 months after the treatment. In addition, the head CT/MRI examination was applied to assess the brain nerve repair before and after the treatment. Results:After the treatment, the total effective rate in the treatment group was 78.0%, versus 42.7% in the control group, showing a statistical significance (P<0.05). As for scores of five subscales in the Gesell scale, there were significant intra-group differences in the treatment group (allP<0.05); and the scores in the treatment group were significantly better than those in the control group (allP<0.05). As for scores of five dimensions in GMFM scale, there were significant intra-group differences in the treatment group (allP<0.05); and the scores in the treatment group were significantly better than those in the control group (allP<0.05). According to the head CT/MRI findings, the total effective rate was 73.3% in the treatment group, versus 62.0% in the control group, showing a statistical significance (P<0.05). Conclusion:When used in combination with rehabilitative training, Governor Vessel-unblocking and brain-refreshing scalp acupuncture can significantly improve the clinical efficacy for cerebral palsy complicated with intellectual disabilities. It can also improve the patients' motor function, intelligence and language ability.

Objective To discuss the relationship of drip velocity of nitrate on blood pressure while treating coronary disease,in order to provide appropriate drip velocity for clinical treatment.Methods 155 patients with coronary disease using nitrate to lower blood pressure were selected.They were divided into the nitro glycerin group(85 cases) and the isosorbide mononitrate group( 70 cases) according to difference of medication.The velocity of drugs was adjusted on basis of blood pressure changes.The blood pressure changes at different drip velocities were observed and compared.Results The systolic pressure and the diastolic pressure between two groups showed no difference at 20 drops/min,but the results were the opposite at 30 drops/min.The systolic pressure and the diastolic pressure in the nitro glycerin group showed evident changes at different drip velocities,but in the isosorbide mononitrate group,these changes were not so significant.9 patients in the nitro glycerin group had headache during treatment,no headache occurred in the isosorbide mononitrate group.Conclusions Intravenous use of nitrate at a velocity of 20 drops/min is relative secure.The risk of hypotension will increase if the medication speed increases.lsosorbide mononitrate has little influence on blood pressure.

Objective To explore the association of NH2-terminal pro-B-type natriuretic peptide ( NT-proBNP) with the risk of type 2 diabetes.Methods One hundred and twenty-six impaired glucose regulation( IGR) participants from Diabetic Identification Center of Tianjin Metabolic Diseases Hospital were included.NT-proBNP was measured in plasma samples collected from participants at baseline condition.Results At baseline, NT-proBNP was inversely associated with body mass index, waist circumference, fasting glucose, insulin and low-density lipoprotein-cholesterol( LDL-C) levels.During a follow-up of 2 years, 51 participants reported a new diagnosis of diabetes from OGTT.Baseline quartiles of NT-proBNP were inversely associated with diabetes risk, even after multivariable adjustment.Theadjustedrelativerisksfordiabeteswere1.0(reference),0.83(95%CI0.74-0.96),0.78(95%CI 0.68-0.90), 0.74 (95%CI 0.64-0.87) for the 1st, 2nd, 3rd, and 4th quartiles of baseline NT-proBNP, respectively ( P<0.01 ) .Conclus ion In IGRpopulation , lowlevels of NT-proBNP were associated with a significantly increased risk of type 2 diabetes.

Objective:To observe the effect of Governor Vessel-unblocking and mind-refreshing needling technique on diffusion tensor imaging (DTI) in cerebral palsy (CP) children with periventricular leukomalacia (PVL) and investigate the underlying mechanism.
Methods:A total of 18 CP children with PVL received modern rehabilitation training and scalp acupuncture. The before-after study was conducted to compare the fractional anisotropy (FA) of the white matter fiber tracts, gross motor function measure (GMFM) score, Gesell developmental scale and changes in muscle tone.
Results:For the comparison before and after the first course of treatment, there were no statistical differences in DTI findings and FA values (both P>0.05); there were statistical differences in GMFM dimensions A and B (bothP<0.05) and no statistical differences in dimensions C, D and E (allP>0.05); and there were statistical differences in six items of Gesell development test (P<0.01 orP<0.05). For the comparison before and after two courses of treatment, there were statistical differences in DTI findings and FA values in 8 cases between before and after 30 and 60 treatments (bothP<0.05); there were statistical differences in GMFM dimensions A, B and C between before and after 30 and 60 treatments and between 30 and 60 treatments (allP<0.05); there were no statistical differences in GMFM dimensions D and E (allP>0.05); and there were statistical differences in six items of Gesell developmental test between before, after 30 and 60 treatments and between 30 and 60 treatments (P<0.05 or P<0.01).
Conclusion:The Governor Vessel-unblocking and mind-refreshing scalp acupuncture has no significant efficacy on the repair and regeneration of white matter fibers in children with PVL and CP in a short period of time; however, it gradually works along with the prolonged treatment time. In addition, it can improve the motor function and mental development and the efficacy is closely associated with the time of treatment.
