Objective:To explore antitumor mechanism of a recombinant vaccinia virus expressing human carcinomembryonic antigen(rV CEA).Methods:C57bl/6 mice were immunized three times with rV CEA.Six weeks later,the splenocytes from rV CEA immunized donors were adoptively tranfered in sublethally irradiated CEA + HePa bearing recipients,meanwhile the antiumor effect of the donor splencytes in virtro was detected.Results:Splenocytes from rV CEA immunized donors expressed strong antiumor activity in CEA positive tumorbearing recipients,whereas W VV immunized and nonimmune donor cell did not.The antiumor activity was abolished when immune T cells were depleted before splencytes transfer.Conclusion:It was demonstrated that antiumor acivity induced by rV CEA was essentially mediated by immune T cells which were activated by CEA specific immune response.Adoptive immunotherapy strategies may have implications for both the study of rV CEA and the development of potential clinical applications for tumor immunotherapy.

Objective To evaluate the diagnosis and efficiency of nasal endoscopic surgery treatment for rhinogenous optic function damage (ROFD).Methods The clinical data of 36 patients (36eyes) with ROFD were retrospectively reviewed.All patients were operated on nasal sinus probing and open sinus surgery through transnasal endoscopic approach,and 10 patients underwent endoscopic optic nerve decompression.Results Seven patients had bilateral pansinusitis,9 patients had unilateral posterior ethmoidal sinusitis and sphenoiditis,8 patients had isolated sphenoiditis,8 patients had fungal sinusitis occured in the sphenoid sinus and unilateral posterior ethmoid sinus,3 patients had unilateral pyocyst and cyst of the sphenoid and ethmoid sinus,1 patient had frontal and ethmoidal sinusitis.All patients were confiemed by pathology after surgery.The visual acuity preoperative were as follows:3 eyes no light perception,10 eyes hand movement,11 eyes fingers counting less than 20 cm and 12 eyes were vision impaired in different degree.The visual acuity postoperative were as follows:3 eyes failed,13 eyes cured,20eyes improved from hand movement or fingers counting to fingers counting (30-60 cm).The efficiency rate was 91.7%(33/36).The other eye symptom was disappeared.Sinus epithelization was happened after surgery in all patients.Conclusions If the medicine expectant treatment is invalid,nasal sinus probing and open sinus surgery through transnasal endoscopic approach should be performed early in treatment of ROFD.Patients who suffered frnm severe visual damage and either unresponsive or intolerant to medical treatment should be administrated endoscopic sinus surgery including endoscopic optic nerve decompression.

?AIM:To study the changes of ocular surface in cataract patients with Meibomian gland dysfunction ( MGD) who treated with Meibomian gland massage before surgery.?METHODS: Totally 90 patients ( 93 eyes ) with cataract and MGD were randomly divided into two groups. Patients in experimental group were treated with hot compress and Meibomian gland massage every day before surgery, while the patients in the control group were not taken. Two groups of patients received phacoemulsification combined with intraocular lens implantation. Lid margin abnormalities, secretion characteristics, Schimer I test ( SⅠt) and tear film break-up time ( BUT ) were recorded and compared between two groups using slit lamp microscope inspection preoperatively and postoperatively 1wk.?RESULTS:In the control group, the postoperative score of eyelid margin and Meibomian gland secretion was increased significantly than preoperative, while the value of BUT and SⅠt was down significantly. Compared with control group, the postoperative score of eyelid margin shape and Meibomian gland secretion in the experimental group was decreased significantly, while the value of BUT and SIT improved significantly (P<0. 05).?CONCLUSION: Phacoemulsification can aggravate the Meibomian gland dysfunction and have some extent of effects on the ocular surface. Meibomian gland massage before surgery can significantly improve the function of Meibomian gland and the state of ocular surface in patients with MDG.

ObjectiveTo investigate the effects of sex hormones( 17 β-estradiol and testosterone)on human omental preadipocytes proliferation and differentiation and on leptin and adiponectin secretions in adipocytes.Methods Omental preadipocytes were cultured and then differentiated into mature adipocytes in vitro.The proliferation and differentiation processes of preadipocyte were observed.The preadipocytes were incubated in the presence of sex hormones and were detected the contents and gene expressions of leptin and adiponectin.ResultsHuman preadipocytes were primarily cultured successfully.Estradiol stimulated preadipocytes proliferation (0.823±0.059 vs 0.276 ±0.032,P<0.05 ),and inhibited lipid accumulation in cell differentiation ( P<0.05 ).Testosterone had no significant effect on proliferation of preedipocytes,but inhibited adipogenic differentiation ( P<0.05).Leptin could be detected during proliferation and differentiation of preadipocytes.Estradiol increased the leptin secretion,whereas testosterone reduced it ( all P < 0.05 ).The adiponectin only could be detected during differentiation.Sex hormones reduced the adiponectin secretion.17β-estradiol stimulated leptin mRNA expression and suppressed adiponectin mRNA expression in adipocytes.Testosterone suppressed the mRNA expressions of leptin and adiponectin (all P < 0.05 ).ConclusionIn vitro,17β-estradiol increases the leptin secretion and mRNA expression whereas reduced the adiponectin secretion and mRNA expression.Testosterone reduced the adiponectin and leptin secretion and mRNA expression.

Cephalosporins are widely used antibiotics owing to their broad activity spectra and low toxicity. Many of these medically important compounds are made chemically from 7-aminodeacetoxycephalosporanic acid. At present, this intermediate is made by synthetic ring-expansion of the inexpensive penicillin G to form G-7-ADCA, followed by enzymatic removal of the side chain to obtain 7-ADCA. The chemical synthetic process is expensive, complicated and environmentally unfriendly. Environmentally compatible enzymatic process is favorable compared with chemical synthesis. In our previous research, metabolic engineered Escherichia coli strain (H7/PG15) was constructed and used as whole-cell biocatalyst for the production of G-7-ADC with penicillin G as substrate. The whole-cell biocatalysis was studied by single factor experiment, including the composition of substrates and the conversion conditions (OD600, pH, concentration of penicillin G, MOPS, glucose, time and FeSO4). After optimization, 15 mmol/L of G-7-ADCA was obtained. The process is convenient, efficient and economic. This work would facilitate the industrial manufacturing and further product research.

Objective To observe The liver lipogenic gene expression of animal model of phlegm and dampness syndrome. Methods According to the theory "Obese people have much more phlegm and dampness", the animal model of phlegm and dampness was built by high fat feeding. After 10 weeks' high fat feeding, we examined liver HE slice, the level of lipids in the normal and model group rats .The liver lipogenic gene expression including LXRα, SREBP-1c, and FAS were detected by fluorescence real time quantative PCR. Results Compared with that of the normal group rat, there was increasing lipids both in serum and liver in the model rats. There was typical appearance of fatty accumulation in the liver cells examined by liver HE staining. The expression of SREBP-Ic and FAS was much higher in phlegm and dampness group than that in the normal group, although there was no difference in the expression of LXRα. Conclusion The fatty accumulation of liver cell in phlegm and dampness group has a close relation to the enhancement of the liver lipoganic gene expression.
