The paper reported the topical skin antiinflammatory activity of bufexamac on inflammation model induced by formaldehyde in mice. Comparing with the blank cream, the effect of 0.5% bufexamac cre-am on inflammation had no statistically difference, but all those of 1% bufexamac cream at 1 and 2 h after treatment, of 2 % and 5 % bufexamac cream at 1, 2 and 4h after treatment, showed significantly difference. The antiinflammatory activity was enhanced with the increase of bufexamac concentration in cream. The antiinflammatory activity of 2 % bufexamac cream was close to the effects of 1 % indomethacin cream and 0.05 % clobetasol Cream.Furthermore, our study showed that steroid antiinflammatory agents and nonsteroid antiinflammatory agents were all active against erythema and edema produced by formaldehyde in mice. Formaldehyde and mice are cheap and easy to obtain in our country. It is of some value to use the animal model for screening the topical skin antiinflammatory agents.

ObjectiveTo understand the clinical characteristics and therapy of Huntington's disease (HD).MethodsThe clinical characteristics of five typical kindreds with HD were analysed. The therapeutic progression after reviewing literature was summarized.ResultsFive kindreds inherited in an autosomal dominant manner. They were all adult-onset HD.Progressive motor dysfunction,cognitive decline,emotional and behavioral disturbance were the key clinical presentations. At an early stage, manifestations include subtle emotional symptoms and involuntary movements.The reason of visiting doctor was chorea. CT scans demonstrated brain atrophy.ConclusionsTypical clinical manifestation and clear family history may be enough to make primary diagnosis. Psychological evaluation at risk individual may help to diagnose early. Gene testing may confirm the diagnosis of HD. The drugs and occupational,physical therapy and psychotherapy for HD patients can help maintain the highest level of function and improve the quality of life.

AIM: To investigate the effect of heme oxygenase on vascular remodeling in renal hypertension. METHODS: Male Wistar rats were randomly divided into sham-operated, 2K1C (two-kidney one-clip) and hemin-induced groups. Four weeks after the treatments, the thickness of aortic media and HO enzymatic activity of the aorta were determined. Immunohistochemical staining was carried out to detect protein of HO-1 in the aorta. RESULTS: The blood pressure in 2K1C renal hypertension rats started to increase two weeks after the surgery and stabled at a high level at the 4th week. Hemin, an inducer of HO-1, markedly inhibited the increase in blood pressure. Aortic medium thickness of the 2K1C rats at 4th week was 27 5% thicker than that in the sham-operated rats. The thickness of aortic medium of the hemin-induced rats was 16 1% less than that in 2K1C group. At the 4th week after operation, protein level and enzymatic activity of HO-1 in aorta were higher than that in 2K1C group compared to those in the sham-operated group. CONCLUSION: Renal hypertension caused vascular remodeling and the activation of HO-1. HO-1 induction decreased the blood pressure of renal hypertension and reduced vascular remodeling.

Objective: To systematically evaluate the willingness to receive influenza vaccines among Chinese medical staff, so as to provide the evidence for developing the influenza vaccination strategy and improving the coverage of influenza vaccination among medical staff. Methods: Publications pertaining to the willingness to receive influenza vaccines among Chinese medical staff were retrieved from international and national databases from January 1, 2010 to October 1, 2023, including CNKI, Wanfang Data, VIP, SinoMed, PubMed, Web of Science and Embase. A meta-analysis was performed using the software Stata 17.0, sensitivity analysis was performed using the leave-one-out method, and the publication bias was evaluated using Funnel plot. Results: Totally 674 publications were retrieved, and 17 case-control studies were finally enrolled, with 23 697 participants. Meta-analysis showed that the rate of willingness to receive influenza vaccines among medical staff in China was 52.8% (95%CI: 41.3%-64.4%). The rates of willingness to receive influenza vaccines were 40.2% (95%CI: 28.5%-51.8%) in 2019 and before and 67.2% (95%CI: 56.5%-77.9%) in 2020 and beyond; 54.6% (95%CI: 44.2%-65.0%) in men and 56.8% (95%CI: 49.3%-64.4%) in women; 53.6% (95%CI: 40.9%-66.2%) in doctors, 53.9% (95%CI: 41.0%-66.8%) in nurses, 62.8% (95%CI: 46.2%-79.3%) in technicians and 53.1% (95%CI: 36.1%-70.0%) in administrative and logistical staff; 77.4% (95%CI: 63.7%-91.2%) and 43.3% (95%CI: 30.5%-56.1%) in staff with and without a history of influenza vaccination; 49.8% (95%CI: 27.3%-72.3%) and 58.3% (95%CI: 43.9%-72.6%) in studies with a sample size of <1 000 and ≥1 000, and these differences were statistically significant (all P<0.05). Sensitivity analysis showed robustness of results, and Funnel plot showed publication bias. Conclusion The rates of willingness to receive influenza vaccines among medical staff in China ranged from 41.3% to 64.4%, and were lower in studies in 2019 and before, in men, in administrative and logistical staff and in staff without a history of influenza vaccination.

Objective To survey on the prevalence of schistosomiasis among floating population in Zhejiang province. Methods A survey on prevalence of schistosomiasis among floating population was conducted from September to November 2008, and the stratified cluster sampling method was adopted in the survey. Totally 129 villages of 19 counties or districts were selected as survey sites, and 100 samples of migrants aged 6 to 65 from schistosomiasis-endemic areas were taken in each selected village. All selected individuals were surveyed by questionnaire and underwent serum indirect hemagglutination (IHA) test. For individuals with positive serum IHA testing the fecal examination was carried out to detect the eggs by nylon sedimentation method. SPSS 13.0 software was used for data processing. Results The number of migrants in survey sites was 3 357 420, among whom 303 219 were from schistosomiasis-endemic areas (9.03%).The positive rate in serum IHA test was 2.06% (286/13 898), 276 IHA-positives individuals received fecal examination, and 7 cases were positive (2.52%). Based on above data it was estimated that there would be potentially about 33 500 serum IHA-positive cases and 845 egg-positive cases among floating population in Zhejiang province. Conclusion The risk of schistosomiasis transmission still exists in Zhejiang province due to the infected migrants from endemic areas, and a surveillance system and quick response are required for prevention of re-emergence of the disease.

Objective To test the RET-proto-oncogene in a multiple endocrine neoplasia type 2( MEN2) family for confirming the diagnosis and classification , guiding treatment and prevention , and improving the prog-nosis.Methods There were 2 patients of MEN2 with clinical diagnosis and 1 asymptomatic first-degree relative in the pedigree .PCR and direct gene sequencing of PCR produces were used to scan the entire 21 exons of RET-proto-oncogene in the 3 members of the pedigree and 3 normal controls .Results The 2 patients and 1 asympto-matic first-degree relative in the pedigree all had a mutation of the codon 634 in exon 11.It was a heterozygous missense mutation C634R(TGC → CGC).The 3 normal controls showed no abnormalities .Conclusion The gene test of RET proto-oncogene helps to confirm the diagnosis of the pedigree as MEN 2, which can guide the treatment and help identify one asymptomatic mutation carrier .

ObjectiveTo identify the finding of functional MRI(fMRI) during active and passive fingers moving in hemipegic patients after stroke.Methods23 stroke patients with hemipegia were asked to actively moving their fingers and then passively moving with others' help.MSEPI technique was performed with planar parallel AC-PC.During each scan series,they were asked to perform repetitive finger-thumb opposition movement in the same period of active and rest.All the scanning data was transferred to a workstation and dealt with statistical method.Some patients examined fMRI again after rehabilitation.ResultsfMRI showed normal in the healthy side,with the decrease or displacement in the affected side of motor cortex area.Motor cortex area in the affected side would be recovered after rehabilitation.ConclusionfMRI can be used to evaluate the difference between active and passive moving motor cortex,and help to judge the prognosis of the patients with motor functional disorder.

Objective To investigate the expression pattern and significance of two importantoocyte-secreted factors:growth differentiation factor 9(GDF9)and bone morphogenetic protein 15(BMP15)during oocyte maturation in women with polycystic ovary syndrome(PCOS)and infertile women due to husband factors.Methods Total of 25 oocytes[9 at germinal vesicle GV stage,9 at M Ⅰ stage and 7 at M Ⅱ stage]were obtained from 12 patients with PCOS and 82 oocytes(29 at GV stage,26 at M Ⅰ stage and 27 at M Ⅱ stage)were from 56 controls.The nested quantitative real time(RT)PCR was uscd to detect the abundance of GDF9 and BMP15 mRNA in each oocyte.Results(1)The expression level of GDF9 mRNA at the GV stage,M Ⅰ stage and M Ⅱ stage in PCOS group were 44.8(4.2-529.0),27.6(9.8-172.7)and 49.0(0.2-65.9)respectively,the expression in were 149.9(55.4-387.9),29.9(2.5-205.8)and 657.8(149.4-1376.2)in control group,respectively.The expression of GDF9 mRNA at M Ⅱ stage was significantly lower in PCOS group than in controls(P ＜ 0.01),however,the differences didn't reach statistical significant at GV or M Ⅰ stage between the two groups(P ＞ 0.05).The expression of GDF9 mRNA displayed some changes at different maturation stage in controls(P ＜ 0.05,P ＜ 0.01),however,the expression didn't demonstrate any dynamic changes in PCOS group(P ＞ 0.05).(2)The expression level BMP15 mRNA at the GV stage,M Ⅰ stage and M Ⅱ stage in PCOS group were 0.1(0.1-22.0),3.2(0.6-55.0)and 6.4(3.2-8.5),respectively,the expression were 41.6(6.5-96.1),4.0(2.0-10.4)and 49.7(2.3-139.5)in control group,respectively.The expression of BMP15 mRNA at GV stage was significantly lower in PCOS group than in controls(P ＜ 0.01),however,the differences were not significant at M Ⅰ or M Ⅱ stage between the two groups(P ＞0.05).The expression of BMP15 mRNA also displayed some changes at different maturation stage in controls(P ＜ 0.05),however,the level didn't demonstrate any dynamic changes in PCOS group(P ＞ 0.05).Conclusion It was suggested that the low expression of oocyte secreted factors in mature oocytes from PCOS patients might be associated with impaired oocyte quality and developmental competence in PCOS.

Objective To analyze the clinical characteristic of spontaneous bacterial peritonitis (SBP) in patients with severe viral hepatitis, and explore its clinical classification and significance. Methods A retrospective research of 120 cases of SBP associated with severe viral hepatitis was performed, and main clinical symptoms and physical signs appeared at the early onset were classified and explored. Results Clinical manifestations of SBP in patients with severe viral hepatitis included 5 types, which were conventional type(41.7%, 50/120), symptomless type(15.8%, 19/120), hepatic coma type(13.3%, 16/120), refractory aacites type (17.5%, 21/120), and shock type (11.7%, 14/120). The germieuhure positive rate of SBP with hepatic coma type and shock type were relatively high, and the survival rate of these patients were low. Conclusions Clinical manifestations of SBP in patients with severe viral hepatitis may be atypical, and its classification help to enhancing the understanding and early diagnosis of SBP, and decreasing missed diagnosis. The prognosis of SBP in patients with hepatic coma type and shock type was poor, and then it must be taken high into account more than ever before in the clinical practice.
