Objective To observe the effect analysis of inverting suture and 8-character-pattern suture after laparoscopic myomectomy for the operation and postoperative complications. Methods The data of of 142 patients with laparoscopic myomectomy were analyzed retro-spectively. According to the different suture methods,they were divided into inverting suture group (85 cases) with straight mattress inverting suture and 8-character-pattern suture group (57 cases). The operation time, intraoperative bleeding, postoperative complications between two groups were compared. Results The operation time and intraoperative bleeding of varus suture group were less than those of 8-character-pat-tern suture group, single tumor posterior uterine wall parts of operation time and intraoperative bleeding than patients with the anterior wall of the uterus and uterine bottom, 1 cases of pelvic related operation infection after operation in eight suture group,abdominal and pelvic mucosa adhesion in 2 cases,the complication rates between two groups were statistically difference (P<0. 05). Conclusion Laparoscopic myomec-tomy with direct mattress inverting suture can shorten operation time, play a good hemostasis in the operation and reduce the incidence of pel-vic infection and abdominal and pelvic mucosa adhesion.

The number of nerve fibers in the spared dorsal root of the L4 spinal nerve and the number of nerve terminals in the Lamina Ⅲ of the segment of the spinal cord between L2 and S1 were determined with electron microscopic morphometry,and the distribution and density of nerve fibers in the spinal cord were observed with silver staining.It was found that the distribution and density of nerve fibers in the spinal cord showed no difference between the operated and the control sides under optical microscopy;morphometric analysis revealed a significant increase of the number of unmyelinated fibers and a tendency to increase of their diameter;and the number of both simple and complex terminals in the Lamina Ⅲ of the spinal cord could return to the normal level on the 35th day after operation with a significant increase of their diameter.The importance of these changes was preliminarily discussed.

Objective To investigate the changes and possible mechanisms of the expressions of metabolic pattern glutamic acid receptor 1(mGluR1) and mGluR3 in hippocampus of juvenile rats submitted to lithium chloride-pilocarpine induced model of epilepsy in 6 h,5 d,60 d after status epilepticus(SE) onset.Methods Seizures were induced in the juvenile rats with lithium and pilocarpine injected intraperito-neally,and behavioral changes and EEG were observed.Eighteen SD juvenile rats with SE were randomly divided into following groups: groupⅠ,in which the rats were killed at 6 h after SE onset(6 h SE),group Ⅱ,in which the animals were killed during the seizure-free period(5 days after SE onset),and group Ⅲ,in which the animals were killed in 60 days after SE induction(period of spontaneous recurrent seizures).And intraperitoneal injection of saline water control groups were divided into: groupⅠa,group Ⅱa and group Ⅲa.The hippocampus tissues after the rats were put to death were collected,the expressions of mGluR1 and mGluR3 mRNA were detected by reverse transcriptase polymerase chain reaction(RT-PCR) in the hippocampus of juvenile rats.Results EEG of rats in group Ⅰ were abnormal,but normal in groupⅡ,and 5(83%) cases of the juvenile rats in group Ⅲ manifested dissemination of sharp waves,spikes or spike wave.The saline control group did not spontaneously attack.There was more significant upregulation of mGluR1 mRNA expression(Pa0.05).The expressional levels of mGluR3 mRNA were upregulated in groupⅠ,group Ⅱ and group Ⅲ(Pa

Objective To investigate the clinicopathological features of human immunodeficiency virus (HIV) negative plasmablastic lymphoma (PBL) with no-immunosuppression,so as to accelerate the understanding for this group of disease.Methods The histological features of 6 HIV-PBL patients with no-immunodeficiency were retrospectively analyzed.Epstein-Barr virus (EBV) status was detected by in situ hybridization.Then,immunohistochemistry and fluorescence in situ hybridization (FISH) method were used to determine the immunophenotype,latent status of EBV and MYC translocation in PBL,respectively.Results HIV-PBL showed monotonous proliferation of plasmablastoid or immunoblast-like cells.Giant cells and necrosis could be observed,with less reactive cells in the background and higher mitoses.All the cases had EBV infection and type Ⅰ latency status of EBV (LMP1-/EBNA2-),and expressed terminal B-cell differentiation immunophenotype (CD20-/CD3-/CD138+/Kappa or Lambda+).Six HIV-PBL patients were elderly (median age was 69.5 years old),had equal incidence of PBL between male and female and showed high frequency of involvement of extranodal and extraoral lesion sites (6 cases and 5 cases,respectively).Median sutvival was 25.5 months.In addition,3 HIV-PBL patients had IGH/MYC translocations.Conclusions HIV-PBL is a new entity with unique clinical features including no-HIV infection,elderly,EBV positivity,and more involvement in extranodal and extraoral sites.HIV-PBL should be distinguished from HIV+ PBL.

12 m/s group,n=70;cfPWV≤12 m/s group,n=49). Carotid atheromatous plaque was assessed by Doppler echocardiograph;blood pressure and hemoglobin A1c were measured. Results After adjustment for body mass index (BMI),sex,stroke and fasting blood glucose,logistic multivariable analysis showed that cfPWV associated with age,systolic blood pressure(SBP),pulse pressure,coronary artery disease,diabetes,carotid atheromatous plaque and hemoglobin A1c. Conclusion Arterial stiffness in elderly patients with essential hypertension was strongly positively associated with age,SBP,pulse pressure,coronary artery disease,diabetes,carotid atheromatous plaque and hemoglobin A1c.

Abstract?Since the introduction of 25-gauge/23-gauge ( 25G/23G ) sutureless micro -incision vitrectomy surgery ( MIVS ) at the beginning of the 21 century, we have stepped into an era of micro-incision vitreoretinal surgery more than10a. The current 25/23G MIVS provide numerous advantages over the conventional 20G vitrectomy surgery including simplified surgical procedure, shortened operating time, decreased complications as well as smaller sclerotomy wound.As a result, vitreoretinal surgeons have been shifting gradually from 20-gauge to 25/23-gauge vitrectomy in the past decade. As the 25/23G MIVS adapted worldwide, however, its drawbacks were also increasingly reported. Most criticism regarding to current 25/23G MIVS are focusing on would sealing related complications.Based on stablished notion regarding vitrectomy -“the smaller the better”, researchers and doctors were keeping on exploring the next generation of vitrectomy system. Thanks to the innovation and development in new generation vitrectomy machines, high lumen output light source, more delicate manufacturing technology and clear wild angle fundus view system, Dr.Oshima from Japan launched the first 27-gauge vitrectomy surgery system.It provided us novel surgical experience with smaller sclerotomy wound and faster cut rate. Further development and refinement of vitrectomy with 27-gauge or more are still on its way and will continue in the future. Undoubtedly, MIVS would be heated debated regarding its pro/con, complications, indications and future development.Combined with our own experiences, here we briefly reviewed the 27-gauge vitrectomy surgery.

Objective To explore the pathological basis and clinical characteristics of children with congenital choledochal cyst(CCC) combined with liver damage.Methods According to the age,38 patients with CCC were divided into 2 groups:group A had 24 cases(ranged 6 months to 3 years old);group B had 14 cases(ranged 4 to 14 years old).A comparative analysis of them was conducted retrospectively in the clinical characteristics,hepatic pathological changes,perioperatively liver function and operation.Results Group A was obvious higher than group B in jaundice,white bole stool and abdominal mass,but group B was more in stomachache.Group A was obvious higher than group B in liver function lesion,alkaline phosphatase,bilirubin increase and blood coagulation disfunction(Pa
