Objective To study the association between human papillomavirus (HPV) genotypes and viral load and clinical features of verruca vulgaris.Methods Tissue samples were collected from 48 outpatients with verruca vulgaris,and DNA was extracted from these tissue samples.To determine the genotype of HPV,PCR was performed to amplify the L1 fragment of HPV with universal primers followed by bidirectional sequencing and BLAST.The genotyping results were validated by PCR with type-specific primers.Real-time fluorescence-based quantitative PCR was conducted to measure the viral load of HPV,and hematoxylin and eosin (HE) staining to observe histological changes in these tissue specimens.Results The L1 fragment of HPV was amplified from 35 out of the 48 tissue specimens.Of the 35 L1-positive specimens,32 harbored HPV 7,1 harbored HPV 57,and 2 harbored both HPV 2 and HPV 7.Multiple lesions were observed on extremities in the patient infected with HPV 57,but on the head,face and trunk in the patients coinfected with HPV 2 and HPV 7.There were no significant differences in HPV viral load or vacuolated cell number between patients with single lesions and those with multiple lesions,or between patients with a clinical course of ＜ 6 months and those with a clinical course of 6-12 months.However,HPV viral load tended to decrease one year after the onset,and there was pronounced hyperkeratosis and less vacuolated cells in lesions of long duration (more than 2 years) compared with those of short duration (less than 2 years).Conclusions HPV 7 appears to be the most common HPV genotype associated with verruca vulgaris,and HPV 7 infection usually occurs on the head and face.For verruca vulgaris of less than 1 year,neither HPV viral load nor vacuolated cell number is associated with the count or clinical course of warts.

Objective To evaluate the efficacy and safety of conventional 2940 nm Er∶YAG laser and pixel laser combination therapy.Methods From Jan.2010 to Jun.2013,32 cases of different types of superficial scars had been treated with this combination therapy.All patients were treated with the low-power 2940 nm Er∶YAG laser,and then immediately with pixel laser at higher power.The morphological changes of the scar before and after treatment,and adverse reaction were recorded.The satisfaction of patients was collected.Results Based on imaging data,significant efficacy was achieved in 14 cases (43.8％),effective in 12 cases (37.5％),relatively effective in 5 cases (15.6％) and ineffective in 1 case (3.1 ％).The total efficacy rate of combined therapy reached 95.3 ％.Very satisfaction to the treatment was 13 cases (40.6％),satisfaction in 10 cases (31.2％),relative satisfaction in 7 cases (21.9％) and no satisfaction in 2 cases (6.3％).The total satisfactory rate reached 93.8％.The only observed side effect was the erythema reaction at irradiated area.Conclusions The combined therapy of conventional 2940 nm Er∶YAG laser and pixel laser is an uncomplicated and safe way to treat superficial scars with little reverse reaction.

Objective:To observe the clinical efficacy of point application with Da Huang (Rhizoma Rhei Cruda) powder at Shenque (CV 8) plus moxa-salt hot compress on the umbilicus for preventing gastrointestinal adverse reactions after chemotherapy for non-Hodgkin lymphoma (NHL).Methods:A total of 60 cases with NHL under chemotherapy were divided into two groups by hospitalization order,with 30 cases in each group.The control group was treated with routine nursing and the observation group was additionally given point application with Da Huang (Rhizoma Rhei Cruda) powder plus moxa-salt hot compress on the umbilicus,to compare the effect in preventing gastrointestinal adverse reactions after chemotherapy between the two groups.Results:The occurrence rates of constipation,nausea,vomiting and poor appetite on the second day and fifth day after chemotherapy were obviously lower in the observation group than those in the control group,with statistically significant differences between the two groups (all P＜0.05).Conclusion:The point application with Da Huang (Rhizoma Rhei Cruda) powder at Shenque (CV 8) plus maxa-salt hot compress on the umbilicus can produce more significant efficacy in preventing the gastrointestinal adverse reactions after chemotherapy for NHL than routine nursing.Moreover,it is simple and easy to be used and popularized.

Objective To investigate the epiderniology of fungemia and provide evidence for clinical therapy.Methods A retro- spective survey was done with the 31 cases of fungemia in our hospital from August 2004 to November 2005.Results More than 80% of the patients suffered from two and more underlying diseases.Over a half of infections developed following placement of catheters.And 83.9% of the patients had a history of antimicrobial agents use before blood culture.The pathogens of 24 (77.4%) cases were associated with Candida spp.Only 3 strains were C.albicans.The mortality rate of candidemia was 45.8%.Different Candida species had different resistance rates to antifungal agents.Conclusions Fungemia patients often have serious underlying diseases.Most fungemia cases were candidemia caused by non-C.albicans.Some fungal pathogens are re- sistant to fluconazole and itraconazole.

OBJECTIVETo explore the effect of Danshensu on the lipid metabolism of hyperlipidemic rats.

METHODSixty clean male SD rats were selected. Twelve of them were selected in the basic control group and fed with common foods, and the remaining rats were fed with the high-fat feeds. After the successful modeling, they were randomly divided into the high-fat control group and low dose (10 mg x kg(-1) x d(-1)), medium dose (20 mg x kg(-1) x d(-1)) and high dose (40 mg x kg(-1) x d(-1)) Danshensu (dissolved in saline) groups. Both of the two groups were abdominally injected with the same volume of normal saline once a day for consecutively 30 days. The serum TG, TC, HDL-C and liver ACC1, FAS, HMGR, CPT-I mRNA expressions were detected.

RESULT AND CONCLUSIONDanshensu could inhibit the LDL-C level, timely clear redundant cholesterol and effectively regulate the lipid metablism of hyperlipidemic rats by reducing the TC content, decrease the fatty acid by reducing the FAS mRNA expression, and reduce the synthesis levels of endogenous cholesterol by inhibit the HMGR mRNA expression.
