Methods： All syphilis patients were confirmed by history, physical examination, dark-field microscopy of samples taken from the chancre or satellite lymph nodes,or positive serological tests. Results： From 1994 to 2002, there were 2067 cases of early syphilis, accounting for 20.01% （2067/10330） of all STD cases. The annual proportion of syphilis cases among all STD cases from 1994 to 2002 was 0.57%, 0.53%, 3.54%, 16.20%, 31.29%, 27.88%, 25.63%, 17.11%, 10.48%, respectively. Of 2067 syphilis patients,49.64% （1026/2067） were male and 50.36% （1041/2067） were female. 44.75% （925/2067） of all cases presented with primary syphilis, 44.90% （928/2067） with secondary syphilis, 9.77% （202/2067） with latent syphilis （without any conspicuous clinical signs or symptoms）, and 0.58% （12/2067） with congenital syphilis. The 30-39 year old cohort accounted for the largest proportion, at 37.68% （779/2067） of all syphilis cases. The 20-29 year old cohort also accounted for a large proportion, at 37.20% （769/2067） of all cases,followed by the 40-49 year old cohort, at 17.95% （371/2067）. Syphilis was most prevalent among the unemployed,self-employed laborers, and office workers in decreasing order. The majority of cases were graduates of either primary school, high school, or college. Of all syphilis cases, 87.86% （1816/2067） were married, and 12.14%（251/2067, including children） were unmarried. 76.78% （1587/2067） of all cases were acquired through extramarital intercourse. 14.03% （290/2067） of cases were infected by their spouses. 0.58% （12/2067） of cases were due to vertical transmission. 8.61% （178） of cases were acquired through indirect contact. Conclusion： The proportion of syphilis infection among all STDs remained stable from 1994 to 1995,quickly and dramatically increased from 1996 to 1999,and then gradually tapered down from 2000 to 2002. The incidence of congenital syphilis infections increased throughout the study period.展开更多

METHODS:We studied 26 patients with NERD and 13 asymptomatic controls.Biopsy sample was taken from the esophagus 3 cm above the gastroesophageal junction and snap frozen for measurement of IL-8 mRNA levels by real-time quantitative polymerase chain reaction(PCR).We also examined mRNA expression of IL-8 receptors,CXCR-1 and -2 by reverse transcriptase PCR.The patients were endoscopically classified into grade M(mucosal color changes without visible mucosal break)and N(neither minimal involvement nor mucosal break)of the modified Los Angeles classification. RESULTS:The relative IL-8 mRNA expression levels were significantly higher in esophageal mucosa of NERD patients than those in esophageal mucosa of the controls.There was a significant difference in IL-8 mRNA levels between grades M and N.The CXCR-1 and -2 mRNAs were constitutively expressed in esophageal mucosa.CONCLUSION: Our results suggest that high IL-8 levels in esophageal mucosa may be involved in the pathogenesis of NERD through interaction with its receptors. NERD seems to be composed of a heterogeneous population in terms of not only endoscopically minimal involvement but also immune and inflammatory processes.展开更多

Methods: A total of 41 cases of appendicitis patients (24 males and 17 females) were subjected into this observation. Electroacupuncture (AA, 60-100 Hz, a bearable stimulus strength) of Pishu (BL 20), Weishu (BL 21), Zhangmen (LR 13) and Wushu (GB 27) was performed beginning 30 minutes before operation. Adjuvants used were luminal (100 mg, intra muscular injection), dolantin (1 mg/kg), 0.5% procaine (1-2 mL). Results: Of the 41 cases, the successful rate was 87.80% and the excellent plus good rate was 75.61% respectively. Conclusion: Acupuncture anesthesia is applicable for appendectomy in clinic but is still to be improved further in operation.展开更多

These patients were found to have severe coronary artery obstructive lesions and an increase of myocardial oxygen consumption (MOC) before the onset to AD, indicating that AD belongs to the category of effort angina.18 patients were investigated by continuous hemodynamic monitoring. Three patients had significant increase in pulmonary artery diastolic pressure (PADP) before the onset. In the other 15 patients. PADP increased slightly in 12 and remained unchanged in 3 cases before the onset. Left ventriculography showed ejection fraction (EF)>45% in 25 of the 27 patients. These results indicate that left ventricular (LV) systolic dysfunction is not a major factor in the Pathogenesis of AD. The patients with LVEDP>12 mmHg constituted 60% of 25 patients with EF>45%, suggesting that these patients had ohvious LV diastolic dysfunction, which may be the major factor in the pathogenesis of AD.According to the results of our treatment, beta blockers may be used as the major form of tteatment in the patients with AD.展开更多

Methods: Sixty three peripheral facial palsy patients were randomized into treatment group (n=33) and control group (n=30). In treatment group, Taiyang (EX HN 5), Jingming (BL 1) and Hegu (LI 4) were punctured with gauge 36 acupuncture needles and stimulated with light twirling reinforcing method (about 200 times/min), the acupuncture needles were retained for 20 min. In addition, moxibustion was also applied to Fengchi (GB 20) and Qianzheng (EX HN 17) following puncturing them with gauge 30 filiform needles. In control group, conventional twirling reducing method (about 60 times/min) was applied to Yangbai (GB 14), Cuanzhu (BL 2), Sizhukong (TE 23), etc., following puncturing them with gauge 28 filiform needles. Additionally, thermal needle was applied to Fengchi (GB 20), Yifeng (TE 17) and Jiache (ST 6), with the needles retained for 40 min. Results: Following 10 days’ treatment, of the 33 and 30 cases in treatment and control groups, 21 (63.0%) and 12 (40.0%) were cured, 7(21.1%) and 5 (16.7%) had remarkable improvement, 4 (12.1%) and 9 (30.0%) were effective, and 1 (3.0%) and 4 (13.3%) failed in the treatment, with the cure plus markedly effective rates being 84.8% and 56.7% respectively. Statistical analysis shows that in acupuncture treatment of early stage of facial palsy, light stimulation is superior to that of heavy stimulation in the therapeutic effect.展开更多

Eighteen weeks after implantation, the Sino implant was removed. There were altogether 16 male volunteers recruited in the entire research program. Among them 6 cases reached azoospermia; one case reached oligozoospermia (sperm density <3 million/ml); 5 cases' sperm density declined greatly, the lowest to be 5.7±1.3 million/ml; the other four cases' sperm density also declined, but remained within normal range (above 20 million/ml), the lowest to be 24.5±9.0 million/ml. The duration to reach azoospermia was 16.7±0.5 weeks. The duration to resume to normal range of sperm density was 8.2±2.5 weeks in the subjects with azoospermia and oligozoospermia. In the first two weeks after insertion the LNG release of Sino implant's mean serum LNG level was about 0.38 ng/ml, in the rest of the time the LNG levels in blood was rather constant about 0.24 ng/ml. Routine analyses of blood and urine, liver and kidney functions, and blood chemistry including those parameters (TG,TC,HDL C,LDL C) of lipid metabolism didn't change much throughout the research. All the subjects' libido and sex function were well kept. Clinical observation didn't show any other adverse effects during the research.展开更多

Despite their low prevalence, the aggregate number of individuals suffering from a rare disease is estimated to be nearly 400 million worldwide.Over the past decades, efforts from researchers, clinicians, and pharmaceutical industries have been focused on both the diagnosis and therapy of rare diseases. However, because of the lack of data and medical records for individual rare diseases and the high cost of orphan drug development, only limited progress has been achieved. In recent years, the rapid development of next-generation sequencing(NGS)-based technologies, as well as the popularity of precision medicine has facilitated a better understanding of rare diseases and their molecular etiology. As a result, molecular subclassification can be identified within each disease more clearly, significantly improving diagnostic accuracy. However, providing appropriate care for patients with rare diseases is still an enormous challenge. In this review, we provide a brief introduction to the challenges of rare disease research and make suggestions on where and how our efforts should be focused.展开更多
