OBJECTIVE:To understand the safety of Puerarin injection in clinical use.METHODS:The adverse drug re?actions(ADRs)and administration of Puerarin injection at Xuanwu Hospital from Oct.2002to Feb.2003were investigat?ed.RESULTS:According to the dosage in drug intruction,the Puerarin injection was diluted in0.9%sodium chloride of5%glucose solution and infused alone with a infusion rate of40～60drops/min,which would be safe and induce less ADRs,and use in overdose markedly increased the incidence of ADRs.CONCLUSION:Use of this preparation should strictly be in accordance with the specification.

Background:As an important catalytic subunit of telomerase,human telomerase reverse transcriptase (hTERT)plays an important role in the development and progression of many cancers including gastric cancer.It has been reported that several single nucleotide polymorphisms (SNPs)of hTERT had varying degrees of association with risk of neoplasms. Aims:To study the correlation between SNPs of hTERT rs2853676 and rs2853677 and susceptibility to gastric cancer. Methods:Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the genotypes of rs2853676 and rs2853677 of hTERT in 297 gastric cancer patients,105 atrophic gastritis and 402 controls. Helicobacter pylori (Hp)infection was detected by pathological examination and 13 C-urea breath test.Results:Frequency of AA genotype of rs2853676 was significantly higher in gastric cancer group when compared with control group (15.2%vs.6.5%,P =0.01).The risk of gastric cancer in AA genotype carriers increased 2.47-fold (95% CI:1.46-4.16) when compared with GG carriers.No significant differences in the frequencies of CC,TC and TT genotypes of rs2853677 were found among gastric cancer patients,atrophic gastritis patients and controls.Hp infection rates in atrophic gastritis group and gastric cancer group were significantly increased than those in controls (64.8%,56.9% vs.40.3%,P all <0.01),OR were 2.73 (95% CI:1.74-4.26),1.96 (95% CI:1.44-2.67),respectively.Logistic regression analysis showed that there was no significant interaction between Hp infection and gene mutation.Conclusions:Polymorphism of hTERT gene rs2853676 may play a role in susceptibility to gastric cancer,and Hp infection may not be involved in the increase of risk of gastric cancer caused by hTERT gene polymorphism.

Objective: Invasion and metastasis are the main causes of carcinoma mortality; hence, the timely blocking of the invasion and metastasis of carcinoma has become a research hotspot. The present study aims to investigate the expression levels of Tiam-1 mRNA and HPA-1 mRNA and their correlation with the invasion and metastasis of hepatocellular carcinoma. Methods: From May 2009 to Jan 2012, 65 hepatocellular carcinoma patients admitted consecutively in our hospital for surgical treatment were included in this study. Real-time fluorescent quantitative reverse transcriptase polymerase chain reaction (RT-PCR) was used to investigate the expression levels of Tiam-1 mRNA and HPA-1 mRNA in hepatocellular carcinoma, paired adjacent hepatocellular carcinoma (2 cm from the carcinoma), and surgical marginal normal hepato mucosa tissues (5 cm from the carcinoma). RT-PCR was also used to analyze their correlation with the clinicopathological characteristics of hepatocellular carcinoma. Results: The expression level of HPA-1 mRNA was significantly higher in hepatocellular carcinoma (43.83±11.62) than in paired adjacent hepatocellular carcinoma (14.82±8.16) and normal hepato mucosa tissues (6.02±5.36) (P<0.001). The expression level of HPA-1 mRNA was higher in paired adjacent hepatocellular carcinoma than in normal hepato mucosa tissues (P<0.05). The expression of Tiam-1 mRNA was higher in hepatocellular carcinoma (35.28±11.81) than in paired adjacent hepatocellular carcinoma (12.94±6.25) and normal hepato mucosa tissues (4.17±3.49) (P<0.05). The expression level of Tiam-1 mRNA was higher in paired adjacent hepatocellular carcinoma than in normal hepato mucosa tissues (P<0.05). The expression levels of Tiam-1 mRNA and HPA-1 mRNA were closely associated with the degree of differentiation, depth of infiltration, lymph node metastasis, vessel metastasis, and TNM (Tumor, Node, Metastasis)staging of gastric carcinoma (P<0.05). Spearman rank correlation analysis demonstrated a significant correlation between Tiam-1 and HPA-1 (OR=0.523, P<0.05). Conclusion: The expression levels of Tiam-1 mRNA and HPA-1 mRNA were high in hepatocellular carcinoma. Meanwhile, the increased ex-pression levels of Tiam-1 and HPA-1 can promote the invasion and metastasis of hepatocellular carcinoma. Moreover, the determination of Tiam-1 and HPA-1 may be valuable for the treatment and prognosis of hepatocellular carcinoma.

Objective To explore the impact of genetic background on pancreatic p-cell first-phase secretion function with L-arginine (L-ARG) stimulation test.Methods Plasma insulin level was detected in 201 cases before and after L-ARG stimulation test.Among them, 61 cases were newly diagnosed type 2 diabetic patients with family history of diabetes ( FH + DM ) , 55 newly diagnosed type 2 diabetic patients without family history of diabetes ( FH - DM) ,31 with normal glucose tolerance and family history of diabetes ( FH + ) 54 with normal glucose tolerance but without family history of diabetes ( FH - ).Homeostasis model assessment ( HOMA) was used to estimate insulin resistance (HOMA-IR).Results It was premised that gender, age and BMI were similar among the 4 groups.(1)TC,TG,fasting plasma glucose,2h plasma glucose,fasting insulin and HOMA-IR in the two groups of newly diagnosed type 2 diabetic patients with or without family history of diabetes were significantly higher than those in the two groups of normal glucose tolerance with or without family history of diabetes.The multiples of the peak level and the base level of insulin secretion in the groups of newly diagnosed diabetes were significantly lower than those in the groups of normal glucose tolerance with and without family history(P <0.05).(2) Insulin secretion reached a peak in 2 minutes and started to decline in 4 minutes in all the four groups.( 3 ) The multiples of the peak level and the base level of insulin secretion in normal glucose tolerance group with family history of diabetes were 20.8% lower than those in the group without family history, being 7.27 and 9.18 respectively ( P < 0.05 ).(4)Two-minute peak insulin secretion, HOMA-IR and age in the newly diagnosed type 2 diabetic group with family history of diabetes was significantly lower than these in the group without family history ( P < 0.05 ).The multiples of the peak level and the base level of insulin secretion in the newly diagnosed type 2 diabetic group with family history of diabetes and that group without family history were 5.18 and 5.31 respectively and there was no significant difference between the two groups( P >0.05).(5) When the normal glucose tolerance subjects with family history of diabetes progressed to suffer from diabetes, the multiples of the peak level and the base level of insulin secretion declined 43.6% (P < 0.05) more than those in the subjects still with normal glucose tolerance without family history.Conclusion In the early course of diabetes, insulin resistance dose not function significantly, but genetic background make the first-phase secretory function of the p-cell to decline gradually and type 2 diabetes occurs easily.In the absence of genetic background, insulin resistance makes first-phase the secretion of insulin to decline relatively slow.

OBJECTIVE: To utilize the clindamycin injection safely.METHODS: 167 cases of hospitalized patients, who underwent clindamycin injection during the period between March 22, 2004 and April 27, 2004 were followed up and analyzed through the self-made questionnaires. RESULTS: 98 cases were for preventing infections; 76 cases were for treating infections; in 107(47+60) cases clindamycin injection was used in combination with other anti-infective drugs to prevent and treat infections; the average dosage was 0.6g～1.2g,bid,and the average length of time was (17?15)d;the incidence of ADR was 6.6%(11/167), and the main clinical manifestations were sickness, vomiting, diarrhea, numbness of mouth and lip, fever, and mycoinfection. CONCLUSION: Only by strict control of signs for drug use and ways of administration can the clinical safety be improved.

The clinical manifestations and CT findings of 26 patients,who were full-time cooks working in small restaurants,were analyzed retrospectively.The main clinical manifestations were chest congestion,shortness of breath,chest pain,cough and hemoptysis.Lung CT scanning revealed lung carcinoma in 1 case,pulmonary nodules in 16 cases including 2 cancerous nodules confirmed in the followup review,puhnonary bulla in 6 cases,emphysema in 4 cases,fibro-proliferative lesions in 8 cases,interstitial pneumonia in 4 cases and fungal ball in 1 case.Among 26 patients,12 had two or more concurrent intrapulmonary lesions.The results suggest that long-term exposure to cooking oil fume may lead to a series of pulmonary pathological changes,and attention should be paid to the occupational hazards of cooks.
