AIM:To report a case of a chronic glaucoma patient whose reduced eyesight is related to ocular ischemia.METHODS:A case report.RESULTS:A 71 year-old man presented with a decreased left eye vision for over 3 years.During the last two months,he had deteriorated blurred vision when he woke up in the morning.The loss of his lower-half peripheral vision was especially serious.The patient suffered from an episode of transient amaurosis fugax three months ago.According to transcranial Doppler ultrasound scan and cerebral computerized tomographic angiography,the patient was found that he had severe stenosis of the bilateral intracranial internal carotid artery and decreased blood flow velocity within the left ophthalmic artery.His symptoms alleviated after an internal carotid artery endarterectomy.CONCLUSION:When vision loss glaucoma cases are presented,more attention should be paid to the presence of ischemia within the ophthalmic artery except glaucoma.

Objective To explore the influence of alimentary tract reconstruction on blood glucose level in gastric cancer patients complicated with type 2 diabetes mellitus. Methods Clinical data of 67 gastric cancer patients complicated with type 2 diabetes mellitus and the level of blood glucose before operation, one month, three month, six month after operation were retrospectively analyzed. BMI of 53 patients was lower than 25kg/m2,9 patients between 25~29.9 kg/m2 and 5 patients was higher than 30kg/m2 .Total gastrectomy with P-type jejunal pouch Roux-en-Y esophagojejunostomy was performed in 26 cases, and total gastrectomy with Roux-en-Y esophagojejunostomy was performed in 11 cases, distal subtotal gastrectomy with Roux-en-Y gastrojejunostomy in 30 cases. Results Operations on sixty-seven patients were all uneventfully. The mean fasting blood glucose level in the morning was 9.6±3.3 mmol/L before operation, 7.4±2.6 mmol/L one month after operation, 7.5±2.3 mmol/L three month after operation, and 7.7±2.9 mmol/L six month after operation. There were significant differences between the blood glucose level of before operation and one month after operation (P<0.05), and there were no significant differences between three month,six month and one month after operation (P>0.05). Conclusions Alimentary tract reconstruction has obviousinfluence on blood glucose level in type 2 diabetes mellitus patients. It takes about one month for reveal the effect of operation. This phenomenon is of value for clinical application. Its mechanism needs further research.

The incidence of low rectal cancer, which severely threatens human health, has been increasing annually in China. Sur-gical operation is the most effective treatment for low rectal cancer. In-depth analyses on the physiology and anatomy of the rectum and the biological characteristics of low rectal cancer have led to the wide application of anus preservation operation as a treatment for this disease. Anus preservation operation is widely used, especially because the application of the laparoscopic technique has recently be-come a popular topic in colorectal surgery. Alternative laparoscopic sphincter-preserving procedures for this disease include the follow-ing: laparoscopic anterior resection; and laparoscopic anterior resection with inter-sphincter resection or with prolapse technique. Colorectal anastomosis with double-stapler technique, hand-sewn coloanal anastomosis, and colonic J-pouch-anal anastomosis are com-mon reconstruction procedures. Each procedure has its own adaptive range, advantages, and disadvantages. Radical surgery must be pri-oritized, but we should also consider the patients' life quality when selecting a mode of surgery.
4. Genetic optimization, recombinant expression and functional study of human augmenter of liver regeneration
Academic Journal of Second Military Medical University 2010;28(12):1284-1287
Objective: To construct recombinant expression vector of human augmenter of liver regeneration (ALR) and study its protective effect on liver function. Methods: ALR cDNA was synthesized and inserted into expression vector pET28a+. The recombinant plasmid was tranformed into BL21 and the expression of ALR was induced by isopropyl-β-D-thiogalactoside(IPTG). MTT method was used for cell proliferation assay; the protective effect of recombinant product on liver function was observed in CCl4-induced acute toxic mouse model. Results: Recombinant expression plasmid of ALR was confirmed correct by restriction enzyme digestion and sequencing. The purified expression product had strong stimulatory effect on hepatocyte proliferation. Low and medium dosages of expression product decreased aminotransferase level in acute chemical injury mouse model. Conclusion: The recombinant expression vector of ALR has been correctly constructed and the expressed rALR can simulate hepatocyte regeneration.

B→O blood conversion has very important meanings in the blood transfusion during the period of peace and war.In the leader of Professor Zhang Yangpei,from Academy of Military Medical Sciences,B→O blood conversion has been achieved by using gene engineering.They obtained the great breakthrough in the domain of blood type conversion.In order to realize standardization and automatization,it is necessary to develop a device applying to B→O blood conversion.This device automatically accomplishes the process of B→O blood conversion,shortens the time of B→O blood conversion to quarter than the time by manual operation,and ensures the standardization and obturation.In the condition of one-off pipeline,this device meets the clinical demands for blood,and lays a foundation for clinical expansion of B→O blood conversion.This paper presented the control system of B→O blood conversion device,including design of software and hardware.This device provides a safe and efficient tool for B→O blood conversion.

[Objective] To compare the biological characteristics of neuron-like cells from rat mesenchymal stem cells (MSC) induced by β-mercaptoethanol (BME) and basic fibroblast growth factor (bFGF) respectively. [Method] BME and bFGF were added to rat MSC respectively for 9 h and 5 days. The neuron-like cells from MSC with the neuron specific protein NF200 were identified using immunofluorescence. The gene expression of NF were analyzed using RT-PCR and the protein expression of NF200 were analyzed using Western blotting. [Results] MSC induced by BME appeared morphology change in an hour and the neurite can be seen at six hour. Some cell bodies became lighter and died. MSC induced by bFGF had neurite in the third day, and appeared network structure in the fifth day, then cells died in the seventh day. At the same time, The result of immunofluorescence showed the NF200 expression of neuon-like cells induced by two ways were beth positive, but MSC induced by bFGF were stronger than those induced by BME. The results of RT-PCR and western blotting were same as that of immunofluorescence. [Conclusion] Both bFGF and BME can induce rat MSC to neuron-like cells, but the neuon-like cells induced by bFGF were more like real neurons in morphology and expression of neuron specific protein and mRNA.

AIM To study the relationship between the response of hypertension patients to Adalat and the C825T polymorphism of the GNB3 gene. METHODS 554 hypertension subjects were treated with Adalat. Epidemiological and clinical data were collected. Genotypes of the GNB3 gene were measured by the PCR RFLP method. Linear and logistic regression were used to analyze the association between GNB3 genotypes and the response to Adalat. RESULTS The frequency of the 825T allele in our hypertensive group (48 4%) was slightly higher than that of the normal Chinese reported previously by Siffert W et al. (42%). The average SBP decrease after 15 days of Adalat treatment of subjects with the T allele was significantly less than that of the subjects with the CC genotype (?=-3 3, P= 0 03). Using logistic regression, the subjects with the T allele were less likely to reach good treatment result compared to those with the CC genotype (OR=0 33, P =0 02). CONCLUSION The GNB3 gene C825T polymorphism is related to the response to Adalat.
