[Frequency, distribution of CD4+, CD8+ T cells and expression of CD38 in gastric mucosa of HIV infections].

Objective: To investigate the frequencies and distribution of CD4+ T cells and CD8+ T cells as well as the changes of immune activation in gastric mucosa of HIV-infected individuals.

Methods: 42 HIV-infected individuals were recruited into this investigation, and 36 patients had definite diagnosis of clinical stage. Biopsy of gastric mucosal tissues was performed by fiberoptic gastroscope including 10 normal people as a control group.

[Primary application of identification-aided system for diagnosis and differential diagnosis of emerging infectious diseases].

Objective: To verify the rate of diagnostic fitting between the clinic and the indentification-aided for diagnosis and differential diagnosis system, for emerging infections diseases (EID) established.

Methods: 314 cases of 49 kinds of contagious diseases diagnosed and another 186 patients with fever who not diagnosed were tested by the system.

Results: Preliminary verification was made in 314 cases diagnosed which classified to 49 kinds of contagious diseases of infectious diseases and the results showed that the coincidence rate of clinical diagnosis and first diagnosis of this system was 61.

Randomized double-blinded and controlled clinical trial on treatment of HIV/AIDS by Zhongyan-4.

Objective: To assess the efficacy and safety of Zhongyan-4 (ZY-4, a Chinese herbal preparation worked out according to the therapeutic principle of supplementing qi, nourishing Yin, clearing heat and detoxication) in treating HIV/AIDS patients in the early or middle stage.

Methods: Adopted was randomized double-blinded and placebo-parallel-controlled method, with 72 HIV/AIDS patients randomly divided into the ZY-4 group (36 patients) treated with ZY-4 and the control group (36 patients) treated with placebo. The treatment course was six months.

[Changes of blood cells in patients with severe acute respiratory syndrome].

Objective: To investigate the changes of blood corpuscles of patients with severe acute respiratory syndrome (SARS) in Beijing.

Methods: Totally 43 patients (21 male and 22 female, 19-74 years old age range) diagnosed as of probable SARS were included in this study. Their corpuscles in the peripheral blood were tested every two days, and the results were analyzed.

[Epidemiologic features, clinical diagnosis and therapy of first cluster of patients with severe acute respiratory syndrome in Beijing area].

Objective: Investigate the features of outbreak epidemic, clinical disease progression of the first SARS cases in Beijing and evaluate the efficacy of therapeutic regimen.

Methods: Twenty-nine patients (11 men and 18 women, 20 - 74 years old age range) were diagnosed with infectious SARS and admitted in our hospital from the March 5th to April 14th, 2003 in this study. The data of clinical presentation and disease progression of all the patients including index subject as the infectious SARS resource patient, her family infected members and 21 health care workers were abstracted.

Objective: To study the clinical, laboratory, and radiologic features of 34 cases of severe acute respiratory syndrome (SARS) in Beijing.

Methods: All patients were admitted to the isolation wards. Their demographic, clinical, laboratory, and radiologic characteristics were analyzed.

The boron-catalyzed polymerization of dimethylsulfoxonium methylide. A living polymethylene synthesis.

Trialkyl and aryl organoboranes catalyze the polymerization of dimethylsulfoxonium methylide (1). The product of the polymerization is a tris-polymethylene organoborane. Oxidation affords linear telechelic alpha-hydroxy polymethylene.
