Objective To evaluate the influence of laparoscopic uterine artery ligation on ovarian function. Methods In this retrospective study ,46 patients with laparoscopic myomectomy were selected and randomly divided into Ligation group and Non-Ligation group. The serum concentrations of follicular stimulating hormone (FSH), luteinizing hormone ( LH), estrogen ( E_2) were measured be-fore treatment and 1 ,3 ,6,12 months after treatment. Ovulating functions of ovary were monitored. All results were compared between two groups. Results All patients ovulated after 6 months. There were no significant differences between two groups in the levels of FSH, LH and E_2,.before and after treatment(P>0.05). Conclusions Laparoscopic uterine artery ligation do not affect ovarian function of pa-tients with uterine leiomyoma.

To explore the antagonistic effect of gingerols against the inflammation induced by lectin from Pinellia ternata. In this study, ELISA method was used to determine the effect of different extracts from gingerols on the release of inflammatory factor TNF-α from macrophages induced by lectin from P. ternata. The fluorescence probe was used to determine the effect of gingerols on the changes in ROS of macrophages induced by lectin from P. ternata. The western-blot method was applied to study the effect of gingerols on the increase in expression of cell receptor interacting protein RIP3 in macrophages induced by lectin from P. ternata. The scanning electron microscope (SEM) was used to study the effect of gingerols on morphological changes in macrophages induced by lectin from P. ternata. According to the results, gingerols can significantly inhibit the release of inflammatory factor from macrophages induced by lectin from P. ternata, ROS overproduction and increase in RIP3 expression. SEM results showed that gingerols can inhibit the cytomorphosis and necrocytosis induced by lectin from P. ternata. Fresh ginger's detoxication may be related to gingerols' effects in inhibiing release of inflammatory factor, ROS overproduction and increase in RIP3 expression caused by macrophages induced by lectin from P. ternata, which are mainly inflammatory development.

Objective To investigate the prognostic sequelae in neontes with hypoxic-ischemic encephalopathy (HIE) and ven-tricnlar dilatation.Methods Seventy-six full term newborns infants with HIE were followed up at the age from 3 to 19 months after therapy. Twenty-five infants among them were followed up by telephone in the epidemic period of SARS.Results Among 76 infants of 88 newborn infants with HIE(84.6%), 73 infants were normal (96.1% ). 1 infant had cerebral palsy (1.3%), 2 infants died (2.6 %).Among 39 cases with mild HIE, none of them had cerebral sequelae; among moderate HIE. 1 infant had cerebral palsy (2.9%) 1 infant died (2. 9 %), interlenkin-4 among severe HIE 50 % died (P00.5 The poor outcome of HIE in those infants were related to intrauterine growth retardation,severe birth asphyxia;and inadequate treatment.Cranial ultra-sonography of 49 infants were done on follow-up,and 12 of them (24.5 % ) had ventricular dilatations, which appeared after birth with 6 infants. Others occurred on follow-up with 1 infant had cerobral palsy,all ventricular dilatations recovered to normal at 12- 19 months except the cerebral palsy.Conclusions The poor outcome of HIE depends on the infants with intranterine growth relarda-tion,severe birth asphyxia and inadequate treatment.The prognosis of transient ventrealar ddatation are good except cerebral palsy.J Appl Clin pediatr,2004,19(12) : 1045- 1047

OBJECTIVETo analysis the early complications of tibial fracture and its related factors, and propose a solution.

METHODSFrom December 2003 to December 2013,38 patients with early complications of tibial plateau fracture after operation were retrospectively analyzed. There were 35 males and 3 females, aged from 37 to 69 years old (averaged 42.3 years). According to Schatzker classification, 3 cases were classified as type II, 2 cases as type III, 2 cases as type IV, 19 cases as type V, 12 cases as type VI. The intervals between injury and operation ranged from 9 hours to 9 days, 26 cases within 3 days. Fifteen cases were treated with internal fixation of plates and 23 were treated by plate fixation and bone transplantation. Early complications included skin necrosis in 15 cases, infection in 6 cases, osteofascial compartment syndrome in 3 cases, common peroneal nerve injury in 2 cases, the superficial peroneal nerve injury in 3 cases, popliteal artery injury in 2 cases, loss of reduction in 7 cases.

RESULTSThe wound of 14 cases healed at the first stage and 24 cases healed delay. Hospitalization days ranged from 7 to 67 days (averaged 25.6 days). All patients were followed up for 12 to 36 months with an average of 16.4 months. The fracture healing time ranged from 3 to 9 months (averaged 6.9 months). According to Merchant knee function evaluation criteria, the results were excellent in 19 cases, good in 12, fair in 5 and poor in 2.

CONCLUSIONEarly complications of tibial fracture after operation is closely associated with the severe fracture complexity and related with preoperative preparation, surgical timing, operation incision selection and surgical technique. Early detection and timely processing reduce damage.

OBJECTIVETo establish fluorescence resonance energy transfer (FRET) assay method of detecting proteolytic activity of non-structural protein 3-4A (NS3-4A) serine protease of hepatitis C virus (HCV) for high throughput screening inhibitors against HCV in vitro.

METHODSHCV recombinant plasmid pMAL~c2/NS3-4A was transformed into the E.coli strain K12TB1. Maltose-binding-protein (MBP) NS3-4A fusion protein expression was induced by adding isopropyl-β-D-thiogalacto-pyranoside (IPTG) and purified by affinity chromatography. The proteolytic activity of MBP-NS3-4A protease was analyzed by FRET with the special protease substrate. The reaction system in this model was optimized, and the reliability of the model was evaluated.

RESULTSHigh throughput screening model for HCV NS3-4A protease inhibitors was established, and the best concentrations of enzyme and substrate were optimized. In the model, the Km value of protease was 4.74 μmol/L, Z factor was up to 0.80, and coefficient of variation (CV) was 1.91%. BILN 2061, one of the known HCV protease inhibitors, was measured with the Ki of 0.30 nmol/L.

CONCLUSIONThe assay model using FRET method for HCV NS3 4A serine protease is stable and reliable, and the model is suitable for high throughput screening for HCV NS3 4A protease inhibitors.

For obtaining new structural compounds with unique resistance profiles or novel mechanisms of action on HIV-1 from natural products, anti-HIV-1 drug screening models were used in vitro. Norcantharidin (NCTD), a derivative from cantharidin, was found to have inhibitory activities on HIV-1(IIIB) p24 antigen in lymphocyte lines MT-4, CEM and H9. It inhibited HIV-1 strain 018a (sensitive to zidovudine) from replicating with EC50 (50% effective concentration) of 14.9 micromol L(-1) and also inhibited HIV-1 strain 018c (resistant to zidovudine) from replicating with EC50 of 20.2 micromol L(-1) in primary lymphocytes peripheral blood mononuclear cells (PBMC). Norcantharidin showed synergistic activity with zidovudine on HIV-1(IIIB) in MT-4 cells, the combination index was less than 0.3. But, it was not active on HIV-1 integrase, reverse transcriptase or protease in vitro. As the structure of norcantharidin is unique and different from that of all clinic drugs approved, it would be possible to obtain new and effective compounds against HIV-1 with low toxicities after modification of norcantharidin.

OBJECTIVETo investigate the clinical significance and diagnosis of testicular microlithiasis (TM).

METHODSWe reported 2 cases of TM, reviewed the relevant published literature and analyzed the clinical significance of the condition.

RESULTSUltrasonographic (US) scanning of the scrotal revealed multiple small calcifications diffusely scattered throughout the testicular parenchyma with rare pinpoint-like 1-2 mm shadows but without acoustic ones, which were diagnosed by scrotal sonography as right limited TM and classic TM accompanied with left varicocele and epididymitis. The testicular tumor markers of AFP, hCG, LDH and testosterone were shown to be normal, so that no intervention was performed for TM. During the 6-8 months follow-up, no abnormality was found in physical examinations and testicular tumor markers, and no characteristic additive change was revealed by testicular ultrasound.

CONCLUSIONTM is a rare, usually asymptomatic and non-progressive abnormality, usually detected incidentally during the ultrasound examination of the testis. Though it is still controversial whether TM should be regarded as a premalignant lesion or not, regular follow-up and routine ultrasound examination are quite necessary for TM patients.

OBJECTIVETo evaluate the risk of nasopharyngeal carcinoma (NPC) through EB virus antibody profile by enzyme linked immunosorbent assay (ELISA).

METHODSEBNA 1/IgA, EBNA 1/IgG and zta/IgG by ELISA and VCA/IgA by immmunoenzymatic method were detected in 121 NPC patients and 332 healthy subjects (HS) in the Pearl river estuary.

RESULTSThe sensitivity rates were 85%, 83% and 79% for EBNA 1/IgA, EBNA 1/IgG and zta/IgG, all three of which if combined was the highest 92%. The specificity rates were 86%, 86% and 80% for EBNA 1/IgA, EBNA 1/IgG and zta/IgG, all three of which if combined was also the highest 93%. According to the level of odds ratio, nasopharyngeal carcinoma risk could be divided into 3 groups: low, moderate and high-risk groups. 93% of HS had low risk of NPC with the odds ratio 0.0 to 0.3. 0.4% of HS had high risk of NPC with the odds ratio of 137.9%.

CONCLUSIONELISA is more objective than the traditional immunoenzymatic method in the detection and diagnosis of NPC. The combination of EBNA 1/IgA, EBNA 1/IgG and zta/IgG is able to evaluate the risk of NPC.
