Retrospective study was carried out in 93 cases of endometrial carcinoma admitted to our hospital since Jan. 1985 to Dec. 1994. Thirty five cases were older than 60 years, and 24 cases were younger than 50 years. All of the cases had pathological diagnosis and were staged according to FIGO. When compared with the younger group, the rate of older patients with stage Ⅰa was higher (11.4% in younger and 45.4% in older, P

Objective To assess the dlagnostic value of a triple stimulation technique(TST)for benign monomelic amyotrophy(BMA). Methods A total of 15 BMA patients and 15 healthy control subiects were exam-ined with the TST.The latent periods,amplitudes,areas and durations of the negative waves of the compound muscle action potential(CMAP)and motor evoked potential(MEP)induced by the stimulation were recorded,and the de-creasing ratio of amplitudes and areas in the two groups were analyzed. Results There were significant differences in amplitude and area ratios between the BMA patients and the healthy control subjects.Both ratios were significantly lower in the BMA patients. Conclusion TST has some value in diagnosis of BMA.

Using chemically defined medium as the control, mechanism of corn steep liquor (CSL) in complex medium during glycerol production by Candida glycerinogenes was studied.The results showed that there were three key factors in CSL that had some great influences on glycerol fermentation of C.glycerinogenes, including phosphorus, nitrogen, and trace elements.The maximum glycerol yield of 53.44% was achieved at an optimal phosphorus concentration of 121.75mg/L, where the CSL concentration was 14g/L.Phosphorus in CSL could control the distribution of carbon metabolism flux between EMP pathway and HMP pathway.With the increase in CSL concentrations, superfluous phosphorus could restrain HMP pathway and activate EMP pathway, thus resulting in remarkable changes in various fermentation parameters of complex medium.Nitrogen in CSL could play a cooperative role in the regulative function of phosphorus.However, it was not a suitable nitrogen source for C.glycerinogenes.Trace elements in CSL could markedly improve the glucose consumption rate, accelerate the cell growth, and enhance the glycerol yield.

Objective To observe the levels of HIF-α and TGF-β in the liver tissue,change of serum transaminase in different phases after paraquat (PQ) toxicity and liver histopathology change in PQinduced liver toxicity of rats models in order to analyze the relationship between HIF-1 α and hepatic toxicity induced by PQ.Methods A total of 48 healthy SD rats were randomly (random number) assigned into 2 groups:PQ poisoning group (n =42,20％ PQ solution,50 mg/kg in 1mL) and control group (n =6,normal saline 1mL).Rats were separately sacrificed and liver tissue samples were harvested at 2,6,12,24,48,72 h and 120 h after PQ administered by gastric lavage.Arterial blood gas (ABG) analysis and serum alanine transaminase were assayed.Liver tissue HE and Masson staining and immunochemistry changes were also investigated.HIF-1α and TGF-β levels were detected by Western blot technique.Results Lactic acid level was significantly higher in PQ group than that in control group at 6 h after PQ exposure (P ＜ 0.05).The level of serum alanine transaminase was increased and significantly higher if PQ group than that in control group at 2 h after PQ poisoning (P ＜ 0.05).The level of HIF-1 α and TGF-β protein in the liver tissue were up-regulated significantly and higher in PQ group than those in control group at 2 h after PQ exposure (P ＜ 0.05).The hepatocytes necrosis and inflammatory cells infiltration were observed around portal area 2 h after PQ poisoning.At 12 h after PQ exposure,the periportal area filled with necrosis of hepatocytes and the necrosis began to extend,and huge amounts of inflammatory cell infiltration were found.Cord-like fibroplasia was found.All the histological changes were around central portal area and were enlarged gradually.Conclusions The results show that there are increased level of HIF-1 α in the early stage of PQ poisoning rats.The liver fibroplasia may be associated with increasing the level of TGF-β promoted by HIF-1α.

Methods of ELISA, nonradioactive molecular hybridiz ation and RT-PCR were applied in the detection of rice grassy stunt virus (RGSV ). The detection sensitivity of indirect ELISA using antiserum against fusion p rotein GST-NC was 1 mg of infected leaves or 84 ng of purified virus. The metho d of dot hybridization using NC, a DIG-labelled DNA probe was 50 μg diseased l e aves, or 6 ng purified preparations. The detection endpoint of RT-PCR was 10 μg diseased leaves, or 2 ng purified virus preparation. Comparisons of sensitivit y and maneuverability were made among these methods.

Cancer, also known as malignant tumor, is the second largest disease after heart disease, which is characterized by genomic instability and mutagenicity. Ataxia telangiectasia and RAD3-related kinase (ATR) are members of phosphatidylinositol 3-kinase (PIKK) family, belonging to serine/threonine kinase, one of the key kinases in DNA damage response (DDR) and DNA repair pathway. This paper reviews the latest progress in the ATR inhibitor field including mechanism of action (MOA), therapeutic applications, and the combination therapy from the perspective of medicinal chemistry. It also discusses the possible challenges and future directions of developing ATR inhibitor antitumor drugs, which could provide the scientists in this field the convenience for access the information and application guidance for clinical studies.

Objective To investigate the clinical efficacy of fire needling in treating endometriosis.Method Fifty-eight endometriosis patients were randomly allocated to treatment and control groups. The treatment group received fire needling at specific points. The treatment was given at one week before menstruation until the end of it, twice a week, three months as a course. The control group took gestrinone 2.5 mg from the first day of menstruation, twice a week, for three consecutive months. The therapeutic effects were evaluated in both groups at three months after the end of treatment.Result The cure rate and the efficacy rate were significantly higher in the treatment group than in the control group (P＜0.05). The pregnancy rate was also higher in the treatment group than in the control group (P＜0.05).Conclusion Fire needling treatment for endometriosis has the advantages of good therapeutic effect, high cure rate and no influence on pregnancy.

Objective The effect of hypoxia inducible factor-1α( HIF-1α) , p-glycoprotein ( p-gp) and human papillomavir-us(HPV) infection on non-small cell lung cancer (NSCLC) and their interrelationship are still not clear .The article aimed to study the relationship between HIF-1αand P-gp, their role in the occurrence , development and multidrug resistance of NSCLC , as well as the in-terrelationship among HIF-1α, p-gp expression and HPV infection . Methods By using immunohistochemistry , the expression of HIF-1αand p-gp was detected in 60 NSCLC tissues and 20 benign lung disease tissues .PCR was employed to detect the expression of HPV16/18 DNA. Results The positive expression rate of HIF-1αand p-gp was 48.3% and 60.0% respectively in NSCLC, but there was no positive expression of HIF-1αand p-gp detected in the benign lung disease group (P<0.05).The expression of HIF-1αwas in positive corelation with p-gp in NSCLC (r=0.313, P<0.05).The detective rate of HPV DNA was 41.7% in NSCLC group and 5.0%in the benign lung disease group , and there was a significant difference between them (P<0.05).The positive expression rate of HIF-1αin HPV DNA positive group and negative group was 52.0% and 45.7% respectively, which showed no significant difference (P>0.05).The positive expression rate of p-gp in HPV DNA positive group and negative group was 64.0% and 57.1%respectively, which showed no significant difference too (P>0.05). Conclusion HIF-1αand p-gp are involved in the occurrence, development and multidrug resistance of NSCLC .HPV infection may be one of the etiological factors in the carcinogenesis of NSCLC . However , neither the HIF-1αexpression nor the p-gp expression is associated with HPV infection .

Objective To evaluate the effect of injection of ozone (O3) through lateral recess for the treatment of radiculitis caused by lumbar disc herniation on the blood glucose in patients with diabetes mellitus.Methods Ninety-six patients with radiculitis caused by lumbar disc herniation involving 48 patients with diabetes mellitus and 48 patients without diabetes mellitus were enrolled in the study.The diabetic or non-diabetic patients were randomly divided into 2 groups ( n =24 each):non-diabetic patients-O3 group (group N-O3 ),non-diabetic patients-ghcocorticoid group (group N-GC),diabetic patients-O3 group (group D-O3 ),and diabetic patients-glucocorticoid group (group D-GC).In N-O3 and D-O3 groups,30 mg/L O3 10 ml was injected via the lateral recess.In N-GC and D-GC groups,compound betamethasone injection 3.5 mg was injected via the lateral recess.The blood glucose level was measured before treatment (T1),1 and 4 h after treatment (T3,4),and 1,3 and 7 days after treatment (T5-7).VAS score was recorded at T1,immediately after treatment (T2),and at T5-7.The patients' quality of life was measured using the Medical Outcomes Study 36-Item Short-Form Health Survey (MOS SF-36 Health Survey) questionnaire at T1,7.The therapeutic effect was evaluated at T7.The side effects were recorded.Results Compared with the baseline value at T1,VAS scores were significantly decreased after treatment,while the MOS SF-36 Health Survey questionnaire scores for physical functioning,bodily pain,role emotional,and mental health in all groups,for general health in group N-GC,and for vitality in groups D-O3 and N-O3 were significantly increased at T7,and the blood glucose level was significantly increased at T4 in groups N-GC and D-O3,and at T3-7 in group D-GC ( P ＜ 0.05).There was no significant change in the blood glucose level before and after treatment in group N-O3.The blood glucose level was significantly higher in group N-GC than in group N-O3,and in group D-GC than in group D-O3 ( P ＜ 0.05).There were no significant differences in the excellent and good rates and all the MOS SF-36 Health Survey questionnaire scores among all groups.No side effects were found in the study.Conclusion Injection of ozone through lateral recess for treatment of radiculitis caused by lumbar disc herniation exerts no influence on the blood glucose level in patients with diabetes mellitus.
