Objective　This study was to investigate the Chlamydia trachomatis (CT) infection rate in cervical secretion of early pregnant and secondary sterility women. Method　CT-DNA in the cervical secretion of the early pregnant, the secondary sterility, and the control women was detected with polymerase chain reaction (PCR). Results　The infection rates of CT in the early pregnant and secondary sterility women （14.28% and 13.33%）were higher than in the control women (3.33%, P<0.05),and there was no significant difference between the former two groups (P>0.05). Conclusion　There are higher infection rates in the early pregnant and secondary sterility women.Detecting CT and treating in the perinatal period are needed in the early pregnant women who want to be pregnant again.

One hundred and seven cases of tetralogy of Fallot (TOF) were surgically corrected in this institute in the period from Jan 1983 to Dec 1989. Adequate corrective procedures were performed in 106 cases and aorto-pulmo-nary shunt with 1.2 Dacron tube in one. The corrective procedures employed included simple intracardiac repair in 18, subpulmonary RV outflow patch in 50, transannular RV outflow patch in 37, and RV-PA coronary conduit in 1 because of anomalous right coronary artery. The operative mortality rate was 13% , and the main complication was low cardiac output syndrome (LCOS) , which occurred in 26 cases (24%) .It was found that the predisposing factors of LOS after corrective surgery for TOF were serious clinical manifestations of the patient before operation, and residual right ventricular outflow tract obstruction due to improper repair of the right ventricular outflow tract, which were fatal in some cases.

Objective:To study intervenient action of Qixue Bingzhi Prescription on the patient of cervical atherosclerosis(AS). Methods:63 cases of cervical AS were randomly divided into a treatment group(n=33) and a control group(n=30), with 25 cases of same age ranges used as healthy group. The control group was treated with basic treatment of western medicine and the treatment group with the basic treatment plus Qixue Bingzhi Prescription for one month. Changes of blood lipid metabolism, interleukin levels, supersensitive C-reactive protein(Hs-CRP) content and the leukocyte adherence expression rate were observed. Results: The total cholesterol (TC), triglyceride(TG), AS index (TC/HDL-C), interleukin-6 (IL-6), interleukin-8 (IL-8) and Hs-CRP levels and lymphocytes and the neutrophilic granulocyte adhesion molecule expression rate (ICD11b and zCD11b) decreased significantly(P 0. 05), Conclusion: Qixue Bingzhi Prescription can effectively and safely intervene in blood lipid metabolism and inflammatory reaction in the patient of cervical AS, and it has prospect of development in preventing formation of AS and stabilizing plaque.

Objective To evaluate the clinical result of modified anterior decompression for the treatment of cervical myelopathy due to ossification of posterior longitudinal ligament(OPLL). Methods From April 1994 to October 2002, 42 cases of OPLL involving 134 cervical segments were operated using modified anterior decompression, among them there were 35 cases, 122 segments of the continuous type; 4 cases, 9 segments of the mixed type; 3 cases, 3 segments of the solitary type. The preoperative index of thickness (O-Index) ranged from 12.4%-78.8%, with an average of 43.2%. A slot was made in the vertebral body through anterior approach and bilateral border of the ossification was dissected from the posterior wall of vertebral body with burr-drill. Results The average follow-up was 3 years and 8 months ranging from 1 year and 6 months to 8 years. The recovery of neurologic function was evaluated according to JOA score: 28 cases with mild neurologic deficit (13-16 points) improved on average 74% postoperatively; 11 cases of the moderately damaged group (8-12 points) improved on 75%; 3 cases of the severely damaged group (

In order to detect and localize melatonin receptor and its mRNA expression in the human skin, human skin was obtained from healthy volunteers. Immunohistochemistry and RT-PCR were applied to detect MR in human skin and to identify its subcellular distribution. Electrophoresis of RT-PCR product showed positive band of mt 1 subtype in human skin. The subtype of MR, mt 1was present in the membrane, cytosol and nucleus of skin cells as shown by immunohistochemistry. It is suggested that skin is the target organ of melatonin.

Objective To investigate the role of mutation of insulin receptor(IR) gene on the development of ischemic cerebral vascular disease.Methods The base variations at exon 17 and 20 of IR gene, by means of PCR SSCP were determined in the 68 cases of atherothrombotic cerebral infarction (ACI), 81 cases of lacunar infarction (LI) and 62 healthy controls.Results There were two alleles of T and C at exon 17 of IR gene. The prevalence of mutant of T allele in ACI patients was more common than that in the controls. The blood pressure and the parameters of blood sugar,lipid metabolism in the patients with mutant were higher than those in the controls with wild type gene. The correlative analysis showed the polymorphism of IR gene was not related statistically to the blood pressure. No base variation at exon 20 was found in the study.Conclusion By promoting the development of atherosclerosis,the mutation at exon 17 of IR gene may participate in the occurrence of ischemic stroke.

OBJECTIVE To investigate the role of cinnabar and realgar in Angong Niuhuang Wan (AGNH) -produced neuroprotection against lipopolysaccharide ( LPS) -mediated neuronal damage and further explore the corresponding mechanisms. METHODS Primary rat midbrain neuron-glia cultures were used as an in vitro model to investigate effects of AGNH on LPS-mediated degeneration of dopamine (DA) neurons. The experiment was divided into normal control group, LPS model group, LPS + cinnabar (4 and 40 mg·L-1) groups, LPS + realgar (4 and 40 mg·L-1 ) groups and LPS + AGNH (40 and 400 mg·L-1 ) group. Drugs were added 30 min before LPS treatment. After 7 d, dopaminergic neurotoxicity was assessed through the quantification of tyrosine hydroxylase (TH)-positive neurons and morphological analysis of TH-positive neurons; the activation of microglia was evaluated using OX-42 antibody; the gene expression of tumor necrosis factor-α (TNF-α) and induced nitric oxide synthase (iNOS) mRNA in microglia was performed by real-time RT-PCR analysis, and the release of TNF-α and nitric oxide (NO) in the supernatant of neuron-glia cultures was determined respectively by the ELISA and Griess reagent. RESULTS Compared with normal control group, DA neurons in LPS model group decreased by 40% (P <0.05) , microglial activation was induced, the expression of TNF-α mRNA and iNOS mRNA in microglia increased 9 and 2 times, respectively ( P < 0. 05 ) , and subsequent production of TNF-α and NO in the supernatant of neuron-glia cultures increased 20 and 30 times, respectively (P<0.05). Compared with LPS model group, AGNH 400 mg·L-1 and realgar 40 mg·L-1 significantly attenuated LPS-mediated DA neuronal loss by 40% and 30% , respectively (P<0.05) and inhibited activation of microglia and expression of TNF-α mRNA by 61% and 52% (P <0.05). iNOS mRNA was reduced by 58% and 51% (P <0.05 ) in microglia. The subsequent release of TNF-α was reduced by 55% and 43% (P<0.05) and NO reduced by 53% and 34% (P<0.05) in the supernatant of neuron-glia cultures. Cinnabar had no inhibitory effect on LPS-induced changes. CONCLUSION AGNH protects LPS-induced neurotoxicity through its anti-inflammatory properties and realgar might be the key contributor to the neuroprotective action of AGNH, while cinnabar fails to show any neuroprotection.

To develop a method for the determination of residual solvents inα-ketophenylalanine calcium by capillary gas chromatography. Methods:The residual solvents were separated on a DB-624(30 m × 0. 32 mm, 0. 25 μm) capillary chromato-graphic column with temperature programming. The column temperature was maintained at 40℃ for 1 min,and then raised to 180℃at a rate of 10℃·min-1 and maintained for 2 min. N2 was used as the carrier gas, and FID was used as the detector with temperature of 250 ℃. The injector temperature was 200 ℃ and the split ratio was 10∶1, and direct injection was adopted. Methanol, ethanol, ethyl acetate and tetrahydrofuran in α-ketoleucine calcium were detected using an external standard method. Results:The four solvents were separated completely. There was a good linear relationship between the peak area and the concentration of each solvent ( r=0. 997 2-0. 999 5). The average recovery of the four solvents was 95. 47%-100. 26%(RSD≤4. 7%, n=9). Conclusion:The method is rap-id, simple, accurate and sensitive, and can be used in the determination of residual solvents in α-ketophenylalanine calcium.
