· AIM: To analyze the pathogeny of corneal endotheliitis and to investigate the causes of its misdiagnosis and the key to treatment.endotheliitis presented with predisposing factors, clinical manifestations and treatment were analyzed retrospectively.junctiviis, and the other 7 were misdiagnosed as acute close-angle glaucoma, glaucomatocyclitic crisis, inflammatory reaction after cataract extracapsular extraction and IOL implantation, disciform stromal keratitis and iridocyclitis, respectively. All the 7 cases were cured through treatment, and recurrence appeared in 1 case.unclear yet. Properly grasping its features and key points for differential diagnosis and seriously and detailed examining patients will benefit to timely diagnosis. After clinical treatment, maintaining treatment for more than 4wk will lower the recurrence of corneal endotheliitis.

AIM: To observe the clinical features of glaucomatocyclitic crisis and to investigate its pathogenesis, diagnosis,treatment and prognosis.METHODS: The clinical data of 15 cases (15 eyes) subjected to glaucomatocyclitic crisis were retrospectively analyzed including clinical manifestation and treatment.RESULTS: Visual field was normal in 13 eyes, and 2eyes had glaucomatous visual field defects. C/D ratio was ≤0.3 in 10 eyes and ≥0.6 in 2 eyes. Through pharmacotherapy the symptoms in 14 eyes disappeared after 2wk. One eye was diagnosed as being complicated by primary open-angle glaucoma and well treated with surgery.CONCLUSION: Glaucomatocyclitic crisis is a kind of ocular syndrome with unknown pathogenesis. It should be differentiated from primary glaucoma and uveitis clinically. Its prognosis is not absolutely benign, and the patients should be followed up regularly.

The immunoregulation effect to polysaccharides from Bifidobacterium spp. was investigated on the base of functional assessment standards of health food. Effects of the EPS on immunity were investigated by promoted the proliferation of spleen lymph cells, delayed type hypersensitivity reaction, the HC50 value and macrophage function assay in mice. Data showed that the EPS could obviously increase the ratio of swallowed chicken red blood cell by macrophage and the HC50 value in mice. However, no significant effect was found on the delayed type hypersensitive induced by sheep red blood cell, for only the low dose of 100 mg/(kg?d) EPS promoted the proliferation of spleen lymph cells. Bifidobacterium spp. EPS can certain immunomodulating function.

Purpose:To study the influence of treatment with high dose progesterone on telomerase activity in patients with endometrial adenocarcinoma.Methods:20 patients were treated for adenocarcinoma of endometrium with high dose progesterone and the change of telomerase activity in tumor tissue was examined by PCR-TRAP ELISA before and after treatment.Results:The average A value of tumor telomerase before and after treatment were 0.3636(0～1.11) and 0.1134 (0～0.556),respectively.It shows that telomerase activity in tumor was decreased by treatment with progesterone (P

Objective To investigate the clinical effects on the hypernatremia in elderly patients with ARDS treated by continu-ous veno-venous hemofiltration(CVVH) .Methods Eighteen cases of elderly patients with ARDS and hypernatremia were treated by CVVH ,the serum sodium concentration was observed and the displacement fluid composition was adjusted dynamically by serum sodium concentration ,the changes of kidney function ,gas index ,plasma osmotic pressure and APACHE Ⅱ score were recorded and analyzed .Results After treatment ,the plasma osmotic pressure of patients declined [(318 .5 ± 20 .2)mmol/L vs .(294 .4 ± 15 .1) mmol/L ,P<0 .01] .After treatment ,the oxygenation index rised [(157 .4 ± 34 .2) vs .(178 .4 ± 40 .4) ,P< 0 .05] ,APACHE Ⅱscore declined[(20 .8 ± 9 .4) vs .(14 .5 ± 8 .8) ,P<0 .05] ,and the comparison of after and before treatment was statistically signifi-cant .Conclusion Therapy method of elderly patients with ARDS and hypernatremia treated by CVVH can correct hypernatremia , improve oxygenation index and APACHE Ⅱ score effectively .

As an interdisciplinary of stomatology and space medicine, space oral medicine focuses mainly on oral diseases happened under space environment. With the manned space technology stepping into the new era, space oral medicine has been put under the spotlight. This article will review the historical events on this subject, summarize the newly progress especially on craniomaxillofacial bone, tooth-derived stem cell and oral microbiology researches and still put forward future prospect.

Objective To study the features of CT and MRI diagnosis of intracranial germ cell tumors ,and to improve the un-derstanding of its imaging findings .Methods Fifteen cases of intracranial germ cell tumors proved by pathology and follow-up were retrospectively analyzed .Results Among the 15 cases with intracranial germ cell tumors ,9 cases in pineal body , tumours showed like-round masses,the margin of the masses were well defined .CT was slightly high density,MRI revealed isointense or hypointense signals on T1 weighted and homogeneous hyperintense signals on T 2 weighted image without edema around tumors and homogeneous en-hancement.One cases in CSF spread.Four cases were identified in the saddle-up area, among the 2 cases was cystic,1 cases was sol-id-cystic and 1 cases was solid,CT was isointense or high density in solid,low density in cystic,without edema around tumors.MRI re-vealed slight-hypointense signals on T 1 weighted and hyperintense signals on T 2 weighted image clearly enhanced in solid , cystoid with-out enhance .In the other 2 cases of intracranial germ cell tumors in the basal ganglia region ,CT was inhomogeneous high density ,inho-mogeneous signals on T2 and T1 weighted image, inhomogeneous enhancement .Conclusions Intracranial germ cell tumors show char-acteristic manifestations on CT and MRI,according to location,shape,signal,age characteristic,which is helpful in diagnosis and differ-ential diagnosis and guide treatment plan .

The diethyl sulfate (DES) mutagenesis was chosen for the mutagenic treatment to Phellinus igniarius, and the relationship of mutagenesis time and death rate was investigated with 0.5% DES. The differences of mycelial growth speed, liquid fermentation mycelia biomass, morphology and pigment classes of secondary metabolites production speed and antioxidant activities of metabolite products were discussed. The study displayed that DES mutagenesis could change mycelial morphology without obvious effect on mycelium growth, and the DES mutagenesis improved antioxidant activities of the active ingredients of P. igniarius and had more antioxidant activity of hypoxia/sugar PC12 nerve cells than that of P. igniarius.

An effective RT-PCR method was developed to detect exogenous gene xylB transcript levels in Zymomonas mobilis CP4. Total RNAs without genomic DNA contamination were purified from wild-type and gene engineering strains, and were quantified to the same concentration. Then, cDNAs synthesis and PCR analysis of these samples were conducted by reverse transcription PCR. The optimal number of cycles was determined by observing amplification profile of target gene xylB and internal control gene 16s rRNA, and relative expression levels of xylB in various samples were analyzed by RT-PCR. The results indicated that the xylB transcript was not be detected in CP4, however that could be found in recombinant strains, in which xylB transcription abundance was similar. The enzyme assay furthermore confirmed that effective ex-pression of the target gene. The method provided a useful and rapid tool for detecting transcript levels of target genes from various samples of Z. mobilis.
