Endobronchial tuberculosis is granulomatous inflammation of the bronchial mucosa characterized by bronchial ulceration due to caseous necrosis. There is a good chance to expectorate cellular components of granulomas in the sputum. The author studied a cytologic series from 46 patients with endo-bronchial tuberculosis confirmed on fiberoptic bronchoscopic biopsy. The cytologic series consisted of 32 sputa, 41 washings, and 17 bronchial brushings, and were carefully screened for elongated epithelioid cells, Langhan's type giant cells, other multinucleated giant cells and caseous material. Elongated epithelioid cells were demonstrated in 9 sputa (28.1%), 30 bronchial washings (73.2%) and 11 brushing smears (64.7%). Langhans' giant cells were observed in two of 32 sputa (6.2%), six of 41 bronchial washings (14.6%) and four of 17 bronchial brushings (23.5%). The caseous materials were noted in 19 of 32 sputa (59.4%), 32 of 41 bronchial washings (78.0%), and 14 of 17 bronchial burshings (82.4%). It appeared that the pertinent cellular components of granulomas in sputa or bronchial secretions indicated a strong evidence of endobronchial tuberculosis of the lung.

Two cases of suprasellar papillary craniopharyngioma are presented. The tumors are exclusively composed of well-formed papillary squamous epithelium and show morphologic homogeneity. There is no palisading basal layer in squamous epithelium. Clinical and radiologic findings, exclusive occurrence in adult and lack of calcification, are much different from conventional craniopharyngioma. Differences between papillary craniopharyngiom and conventional craniopharyngioma are discussed.

Objective To detect and analyze the HBV?related indexes in the urine of HBV transgenic mice and further understand the biological characteristics of transgenic mice, and to clarify the tissue sources of HBV?related indexes. Methods HBV?related indexes in the urine of transgenic mice were tested using enzyme?linked immune sorbent assay ( ELISA ) and fluorescence quantitative PCR ( real?time RCR ) . The tissue sources were confirmed by several experiments, i. e. hydrodynamic transfection of mice, RNA interference to inhibit HBV?expression in the transgenic mice, and to infect normal mice with HBV?positive serum from patients. Results Expression of HBsAg, HBeAg and HBV?DNA was present in the urine of transgenic mice, of which the HBsAg expression level was high (6674 ± 619?8 IU/mL), but lower than that in the serum (16470 ± 2704 IU/mL). The level of HBsAg expression in the urine of male mice was higher than that in female mice. The level of HBeAg expression in the urine was lower and the HBeAg positive rate of urine was higher than that of blood, and the levels of HBeAg expression showed significant inter?individual and inter?sexual differences. HBV?DNA level reached 103 -105 copy/mL in the urine, but no related antibody expression was detected. The experiments such as hydrodynamic infection test indicated that the HBV?related indexes in the urine are derived from replication in the kidneys rather than secreted from the liver, entered into the blood circulation, and discharged from the urine. The kidneys are an independent expression site of HBV. Conclusions The expression of HBV?related indexes is present in the urine of transgenic mice and it is a long?term expression along with the age in months, of which the expression levels of HBsAg and HBV?DNA are rather high and stable. HBsAg titer in the urine of the male mice is higher than that of female mice. HBeAg expression level in the male mice is more stable compared with that in female mice. No expressions of various kinds of antibodies have been found in the urine. The kidneys are an independent expression site of HBV.

AIM:To study the inhibitory effect and its mechanisms of the extract of Oratosquilla oratoria (EOS) on the activity of telomerase in human nasopharyngeal carcinoma cell line CNE-2Z. METHODS:MTT assay was used to determine the effect of different doses of EOS on the proliferation of CNE -2Z cells. The activity of telomerase was analyzed by TRAP-ELISA. The mRNA expression of hTERT was determined by RT-PCR,and the protein expression of c-Myc was detected by Western blotting. RESULTS:EOS inhibited the proliferation of CNE-2Z cells in a dose-dependent manner (P

Objective To compare the clinical efficacy of acupuncture and medicine for the treatment of chronic pharyngitis. Methods Sixty chronic pharyngitis patients were randomized into treatment group and control group, 30 cases in each group. The treatment group was treated with acupuncture mainly on acupoints of Zhaohai(KI6), Lieque(L7), Tiantu(CV22) , Lianquan(CV23), Tianrong(SI17) , Hegu(LI), Yuji (LU10) for nourishing yin to reduce fire and clearing throat. The supplementary acupoints were selected according to the symptoms and physical signs. Acupuncture was performed once a day and 6 times a week. The control group received western medical therapy including pharyngeal application with 1% iodine glycerin preparation and oral use of Cydiodine tablets, 3 times per day. Four weeks constituted one treatment course and the treatment for the two groups covered 2 courses. After treatment, the therapeutic effect was evaluated. The scores of the signs and s ymptoms as well as scores of chronic pharyngitis syndrome discomfort rating questionnaire(CPSDQ) evaluated by visual anal og scale(VAS) were observed. Results (1) The overall effective rate of the treatment group was 93.3%, higher than that of the control group(73.3%), and the inter-group difference was statistically significant (P<0.05). (2) After treatment, scores of the signs and symptoms and VAS for CPSDQ scores in the two groups were reduced as compared with those before treatment(all P<0.05 or P<0.01 ) .The improvement of the scores in the treatment group was superior to that in the control group(all P<0.05 or P<0.01).(3) During the treatment , needling-induced mild pain and bleeding occurred in the treatment group. No acupuncture syncope, stuck needles or allergic and toxic-side effect was shown in the two groups. Conclusion Acupuncture therapy can obviously relieve the symptoms, signs and discomfort in the patients with chronic pharyngitis, and the curative effect is superior to the drugs.

A protease from the culture supernatant of marine bacteria Pseudomonas sp. 7~11 was discovered. One component of the protease was purified to homogeneity by ammonium sulfate precipitation, dialysis, ion exchange chromatography. The specific activity of the enzyme was raised from 19.46U?mg -1 to 13953115U?mg -1 ,which was 717.02 times that of the culture supernatant with a yield of 1.24%.The molecular mass of purified enzyme was estimated to be 3000Da about by SDS PAGE. The optimum temperature for the activity was observed to be 45℃ using casein as substrate.The optimum pH for activity the enzyme was 8.0 and it was stable between pH6～7 and below 50℃.The activity of the enzyme was inhibited by EDTA and IAA strongly. But was not inhibited by PMSF. the enzyme was inhibited Mn 2+ , Hg 2+ , Fe 2+ , Zn 2+ , Cu 2+ ,Pb 2+ and SDS. The inactivity of the enzyme with EDTA could be recovered partially by Mg 2+ .while Ca 2+ , Mg 2+ and (NH 4) 2SO 4 was activator for the activity of the enzyme. The activity of the enzyme was fairly stable in the presence of ethanol and urea, and was resistant to Tween 20.

Objective:To study the levels of TNF ? in serum and in urine and IL 6 in serum of renal allograft recipients with acute rejection, infection and CsA induced nephrotoxicity.Methods:The sequential monitoring of TNF ? and IL 6 was conducted by ELISA technique in 106 patients before and after renal transplantation.Results:The levels of IL 6 and TNF ? increased in the first day posttransplant, decreased and stabilized after 1 to 2 weeks, and increased 1 to 3 days prior to the clinical diagnosis in acute rejection, then decreased with effective treatment. IL 6 and TNF ? increased in serum in infection and had no difference in urine. TNF ? in serum and in urine and IL 6 in serum had no significant difference in CsA induced nephrotoxicity.Conclusion:It suggests that the sequential monitoring of IL 6 and TNF ? of renal allograft recipients can be used to estimate the function of graft, as markers of the early diagnosis of acute rejection.

The meridians belong to zang-fu organs inside and connect with the extremities outside. They keep information exchange among different tissues and make various organs of the human body as an organic whole. If the meridians are blocked and the information exchange makes mistake, the body will produce pathologic changes. Because the location of the blocked part is difficult to identify, in this paper it is explained that selection of distal acupoints is the best way to dredge the nodes of disease, and the theoretical basis is closely related with the theories of "the root cause and symptoms of a disease", "Genjie", and "Jing, Xing, Shu, Jing, He", and also implies the thought of "to cure a disease must treat the root of the disease".
