3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) is the first rate-limiting enzyme for sesquiterpene synthesis in the mevalonate (MVA) pathway. The specific primers were designed according to the transcript sequence of AsHMGR2 from the Aquilaria sinensis (Lour.) Gilg transcriptome database. The full-length cDNA of AsHMGR2 was cloned by RT-PCR and rapid amplification of cDNA ends (RACE) technology, and was analyzed at bioinformatics levels; AsHMGR2 expression profiles in different tissues and in responds to different treatments were analyzed by real-time PCR. The length of AsHMGR2 Open Reading Frame (ORF) was 1 749 bp, encoding 582 amino acids. The GenBank accession number is KC140287. Tissue expression analysis indicated that AsHMGR2 was mainly expressed in root and shoot tips, followed by stem, and was lowest in leaves. Inducible-experiments showed that the genes were induced by mechanical wound as well as chemical liquid induction, and reached the highest expression level at 6 h and 8 h, separately. The full-length cDNA of AsHMGR2 and its expression patterns will provide a foundation for further research on its function in agarwood sesquiterpene biosynthesis.

ObjectiveTo evaluate the diagnostic value of ultrasound or CT guided percutaneous Trucut needle biopsy on the diagnosis of pancreatic tumors.Methods One hundred and twenty-four patients clinically diagnosed as pancreatic cancer without pathological diagnosis underwent percutaneous pancreatic biopsy by using Trucut needle under ultrasound or CT guidance.ResultsOne hundred and nine procedures of ultrasound-guided biopsy and 15 procedures of CT-guided biopsy were performed,and one patient received 2.3times of punctures.Tissue samples were obtained in all 124 patients,the diagnostic accuracy was 95.2%,among them 115 were adenocarcinoma,5 were cystadenoma,2 were metastasis cancer,1 was cancer of unknown origin and 1 was normal.The sensitivity,specificity,and accuracy were 99.2% 100%,and 99.2%,respectively.Transient serum amylase increase was observed in 3 patients; 5 patients' abdominal pain aggravated,but all recovered with conservative management.One patient was found to have tumor seeding on the spot of insertion after 34 days.No other major complications occurred.ConclusionsUltrasound or CTguided percutaneous pancreatic 16 ~ 18G Trucut needle biopsy is a safe and simple procedure with excellent diagnostic value for pancreatic cancer.

Objective To discussed the relationship between multiple sclerosis(MS)and the genepolymorphism of HLA hoping that these results would be useful for further pathogeny studies,diagnoses,therapy and prognosis estimation of MS.Methods HLA-Ⅱ alleles in 32 patients with MS,36 nonimmunological neurological disease controls and 30 healthy controls,were identified by polymerase chain reaction-specific sequence primers(PCR-SSP)methods.Results The gene frequency of HLA-DR16 (7/32,1/36,0/30),DR11(7/32,3/36,1/30)and DQB1*0502(10/32,6/36,4/30)in patients with MS were higher than those in the 2 control groups.The gene frequency of DQB1*0601(8/32,12/36,17/30)in the patients with MS was lower than the controls.However,only the HLA-DR16 had significant difference (χ2=7.398,RR=17.94,P=0.011;χ2=5.52,RR=9.8,P=0.022).Conclusion HLA-DR16 alleles may be associated with the susceptibility to MS in Guizhou Province.

OBJECTIVE:To compare the clinical efficacy and safety of Kangshuling gel,mupirocin and lactate ethacridine in the treatment of diabetic foot. METHODS:90 patients with diabetic foot were randomly divided into Kangshuling group,mupiro-cin group and lactate ethacridine group. All the patients were treated by lowing blood glucose,nutritional support,improving micro-circulation and anti-infection,etc. On this basis,3 groups were given Kangshuling gel,Mupirocin ointment and Lactate ethacridine solution for wet compress by gauze. The course was 180 d. The clinic data was observed,including clinical efficacy,and wound ar-ea,healed patients’granulation,epithelial tissue,healing time and incidence of adverse reactions before and after treatment. RE-SULTS:The total effective rate in Kangshuling group was significantly higher than mupirocin group and lactate ethacridine group;healed patients’granulation,epithelial tissue and healing time were significantly shorter than mupirocin group and lactate ethacri-dine group,with significant differences(P<0.05). After treatment,wound area in each group were significantly smaller than be-fore,and Kangshuling group was smaller than mupirocin group and lactate ethacridine group,with significant differences(P<0.05);there were no significant differences between mupirocin group and lactate ethacridine group(P>0.05). There were no obvi-ous adverse reactions during treatment. CONCLUSIONS:Based on the conventional treatment,Kangshuling gel has better efficacy than mupirocin and lactate ethacridine in the treatment of diabetic foot,with good safety.

OBJECTIVE:To explore the clinical features and regularity of drug-induced liver injury (DILI),and to provide reference for clinical rational drug use. METHODS:104 DILI cases in our hospital from 2005 to 2014 were selected and analyzed retrospectively in respects of patient’s gender,age,allergic history,medication history,drug type and clinical manifestations. RE-SULTS:DILI hospitalized cases increased year by year. There were 47 males and 57 females,and average age was(8.71±13.90). The clinical symptoms appeared within 12 weeks after using the drug. The symptoms were no specific,including weak,anorexia, jaundice,yellow urine,etc. and 10.57% of patients were asymptomatic. Most of the DILI cases were hepatocyte type(80.77%), followed by cholestasis type(12.50%)and hybrid type(6.73%). The most common cause of drug-induced liver injury were TCM, antimicrobial drugs and the nervous system drugs. CONCLUSIONS:The incidence of DILI in females is slightly higher than males. DILI often occurs after 40 years old. The clinical symptoms have no specificity and are similar to viral hepatitis. The hepatic lesions can be caused by most of drugs. DILI by TCM should concerned. Clinical physicians should pay more attention to DILI.

Objective To explore the application of single-person operated mammotome minimally inva-sive surgery in treatment of benign breast lesions. Methods Clinical information of 403 patients were collected and retrospectively analyzed. 262 patients receiving ultrasound guided single-person operated mammotome mini-mally invasive surgery for benign breast masses were selected as the treatment group,141 patients undergoing open surgery for treatment of benign breast masses were selected as the control group.Operative time, introopera-tive blood loss,length of stay,postoperative healing time, as well as the occurrence of complications were com-pared between the two groups. Result Compared with the control group, the operative time was shorter, the in traoperative blood loss was less, the scar size and the postoperative healing time were shorter for the treatment group. The difference had statistical significance (P<0.05).The rate of postoperative pain, local ecchymosis, local infection and breast deformity for the treatment group was significantly lower than those of the control group (P<0.05). The difference had statistical significance (P<0.05). The recurrence rate between the two groups had no sta-tistical significance (P>0.05). Conclusions Single-person operated Mammotome minimally invasive surgery has the advantages of good operative time,good cosmetic effects, small surgical trauma, less blood loss, fast postoper-ative healing and few complications, which is worthy of clinical application.
