OBJECTIVETo study the effect of Qinghuang Powder (QHP) combined Chinese herbs for Pi-strengthening and Shen-reinforcing (CHPSSR) on hypoxia-inducible factor 1alpha (HIF-1alpha) in bone marrow mononuclear cells of myelodysplastic syndrome (MDS) patients.

METHODSChanges of HIF-1alpha in bone marrow mononuclear cells of MDS patients were detected in 25 MDS patients treated by QHP combined CHPSSR using flow cytometry. Meanwhile, 13 healthy subjects were recruited as the control group. Changes HIF-1alpha levels in various serial bone marrow mononuclear cells were detected.

RESULTS(1) Among the 25 patients in the treatment group, there were 19 patients effective and 6 patients ineffective, with the total effective rate being 76%. (2) Compared with before treatment, levels of peripheral blood WBC, Hb, PLT, and ANC significantly increased in the treatment group after treatment, showing statistical difference (P < 0.05, P < 0.01). (3) Compared with before treatment, the HIF-1alpha mean fluorescence intensity was enhanced in bone marrow lymphocytes, monocytes, granulocytes, and nucleated red blood cells of the treatment group after treatment (P < 0.05, P < 0.01). Compared with the control group, the HIF-1alpha mean fluorescence intensity was weakened in bone marrow lymphocytes, monocytes, and nucleated red blood cells of the treatment group before treatment; while it was obviously enhanced in granulocytes (P < 0.01). But after treatment the HIF-1alpha mean fluorescence intensity increased more in the granulocytes of the treatment group than in those of the control group (P < 0.01), but there was no statistical difference in bone marrow lymphocytes, monocytes, or nucleated red blood cells.

CONCLUSIONQHP combined CHPSSR could improve HIF-1alpha levels in bone marrow lymphocytes, monocytes, granulocytes, and nucleated red blood cells of MDS patients, thus improving Hb levels of MDS patients, and improving their anemia and correlated symptoms.

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 investigate the status of human papillomavirus ( HPV) infection and its genotypes in male patients in Zhenjiang area.

METHODSUsing PCR and reverse dot blot hybridization, we determined the genotypes of HPV DNA in 245 male patients at our Clinic of Dermatology and STD.

RESULTSThe total rate of HPV infection was 43.67% (107/245), and 18 subtypes were detected. Among the 107 HPV-positive cases, low-risk, high-risk, and combined high- and low-risk infections accounted for 39.25% (42/107), 38.32% (41/107), and 22.43% (24/107), respectively. The most notable low-risk HPV types were HPV6 and HPV11, and the most notable high-risk HPV types were HPV16, HPV52, and HPV58. The rates of single infection and multi-infection were 53.27% (57/107) and 46.73% (50/107), respectively. One case had the most types, infected with 8 genotypes. No statistically significant differences were observed in the total rate of HPV infection among different age groups (Χ2 = 7.999, P > 0.05).

CONCLUSIONThe dominant subtypes of HPV infection in male patients in Zhenjiang area were HPV6, HPV11, and HPV16. The most common subtypes were HPV6 and HPV11 in low-risk infection, and HPV16, HPV52, and HPV58 in high-risk infection.

Objective To modify the methods of operation and establishment of cerebral ischemia rat models made by thread occlusion. Method We randomly divided 120 male SD rats into a common group (n = 50), an improvement group (n = 60) and a sham-operated group (n - 10). Rats in the common and improvement groups were made into models using the common and improvement methods separately. All models were evaluated on the basis of physical sign indices and 2,3,5-triphenyltetrazolium chloride (TTC) staining. The TTC staining results were taken as gold standards. Then, we compared the achievement ratios of the two groups, and computed the sensitivity and specificity of every physical sign index based on these standards. The χ~2 or correction χ~2 test was used to compare the ratios. Results (1) The achievement ratio in the improvement group was significantly higher than that in the common group (71.67% vs. 52.00%, P = 0.034). (2) The sensitivity of evaluation for both common and improvement methods was 98.55%. However, the specificity of evaluation for the improvement method was significantly higher than that for the common method (100.00% vs. 40.00%, P =0.000). Conclusions The establishment achievement ratio and evaluation correctness of models are obviously elevated by modification of the operation and establishment methods.

Objective To review the clinical and histopathological features,management and outcomes in 67 patients with seba- ceous carcinoma of the eyelid.Design Retrospective case series.Participants Sixty-seven cases of the sebaceous gland carcinoma were retrieved from the ophthalmology archives of Tongren Hospital between 1996 and 2005.Methods Clinical data of all patients were re- viewed from the charts.Pathology specimens were reviewed in all cases.Main Outcome Measure Presenting features,sites of origin, location,differentiation,management,histopathologic findings,and incidence of recurrence in 67 patients.Results A total of 36 female and 31 male patients were identified.The mean age at diagnosis was 59 years (range from 35 to 84).Initial clinical diagnoses elsewhere were sebaceous carcinoma (43.28%),chalazion (25.37%),basal cell carcinoma(7.46%).Initial histopathologic diagnoses were sebaceous carcinoma(79.10%),basal cell carcinoma(5.97%),squamous cell carcinoma(1.49%) and other or not available(4.48%).The initial treat- ment involved excisional techniques with reconstruction in 42 cases,anti-inflammatory in 12 cases,without any treatment in 10 cases. 61.19% cases presented the pagetoid invasion.Local recurrence developed in 58.21% and two died from metastatic sebaceous carcino- ma (8.70%).Regional lymph node excision was performed in 13.04% because of local metastases.Five year survival rate was 94.87%. Conclusions About 1/3 cases had not receive the right treatment at initial diagnosis eyelid.The recurrence rate of patients was still high.

Objective To study the prevalence of fatty liver and its risk factors in adult population of Pudong New District,Shanghai detected by combination of B-type uhrasonographic features and elevated serum activity of alanine aminotransferase (ALT).Methods A cross-sectional survey was performed in 2017 residents aged 16 years over recruited from four neighborhoods of Prdong New District of Shanghai with multi-phase cluster sampling,including interview with questionnaire,physical check-up,anthropometry, measurement of plasma glucose and lipid profile,ALT activity and real-time B-type ultrasnnography.Serum hepatitis B surface antigen (HBsAg) was further detected for those with elevated ALT activity.Results Prevalence of fatty liver was 21.32 percent (430/2017) in the residents of the District participated in this survey.Prevalence of abdominal obesity,hypertriglyceridemia,hyperlipoproteinemia (low-density lipoprotein-cholecterol),essential hypertension,impaired glucose tolerance,diabetes and metabolic syndrome were 71.16,71.16,11.86,66.74,35.58,24.40 and 47.21 percent in those with fatty liver, respectively,as compared to 26.34,12.73,4.79,39.57,24.01,6.81 and 11.28 percent in those without fatty liver (controls),respectively.Multivariate logistic regression analysis showed that body mass index, 2-h postprandial glucose level,diastolic blood pressure,serum level of triglyceride,abdominal obesity and diabetes all were independent risk factor for tatty liver,with odds ratio (OR) of 1.080,1.149,1.035, 1.526,1.960 and 1.391,respectively.Conclusions Prevalence of fatty liver was relatively high in Shanghai Pudong New District.Fatty liver closely associates with disturbance of carbohydrate and lipid metabolism.

BackgroundOsteopontin is highly expressed in many metastatic tumors,but its expression in uveal melanoma and the relationship of osteopontin with metastasis is still under investigation.Objective This study was to investigate the relationship between osteopontin expression and uveal melanoma metastatic potential.Methods Fifty samples of uveal melanoma were collected in Beijing Tongren Hospital.The expressions of osteopontin in the samples were detected using immunohistochemistry,and expressions of osteopontin mRNA in different metastatic potential uveal melanoma cell lines (MU M-2B,C918,OCM-1A) were analyzed using quantitative polymerase chain reaction (Q-PCR).ResultsOsteopontin was positively expressed in 10 samples of 13 patients with metastasis and 14 samples of 37 patients without metastasis,showing a significant difference between them (x2=5.888,P=0.000).There were 11 samples and 13 samples exhibiting the positive expression of osteopontin in 15 epithelial type and 35 non-epithelial type of uveal melanoma respectively with the significant difference (x2=5.510,P =0.000).The positive expressing numbers of osteopontin were 20 tumors of 30 affected tumors and 4 tumors of 20unaffected ciliary tumors with the significant difference (x2 =10.470,P =0.000 ).No significant differences in the expression of osteopontige were found between different gender,age,eyes,largest basal diameters and invasion of scleral canal( P =0.536,0.256,0.802,0.848,0.555 ).The relative expression value of osteopontin mRNA was in turn 1.00±0.04,0.91 ±0.03,0.08±0.01 in MUM-2B,C918,OCM-1A with the significant difference among three cell lines( F=33.135,P＜0.05).The osteopontige mRNA expression was significant enhanced in high metastatic potentialcell lines( MUM-2B,C918 ) compared with low metastatic potential cell lines( OCM-1 A) (P＜0.05 ),but no significant difference was seen between two high metastatic potential cell lines(MUM-2B,C918) (P=0.804).Conclusions Osteopontige expression is associated with the uveal melanoma cell line invasion and metastasis potential.These results imply that osteopontige expression maybe an indicator of uveal melanoma invasion and metastasis ability.
