Chinese Journal of Ocular Fundus Diseases 2015;31(2):165-168
Objective To observe the effects of bulbar subconjunctival and periocular injection of dexamethasonone on blood glucose levels of type 1 diabetic mellitus (T1DM)rats.Methods 80 healthy adult male Sprague-Dawley rats were randomly divided into Group Ⅰ (n-=-40) and Group Ⅱ (n =40).Group Ⅰ rats received intraperitoneal (IP) injection of streptozotocin to induce T1DM model,while Group Ⅱ rats received IP injection of citrate buffer solution and was the control group.Group Ⅰ rats and Group Ⅱ rats were further divided into four subgroups:A (n=10),a (n=10),B (n=10),and b (n=10).Subgroup-A rats received bulbar subconjunctival injection of dexamethasone,subgroup-a rats received bulbar subconjunctival injection of saline,subgroup-B rats received periocular injection of dexamethasone,subgroup-b rats received periocular injection of saline.After the injection,rats were fasted but could drink water.Tail vein blood samples were collected and the blood glucose level was measured by glucose monitor.Results After modeling,the blood glucose level of Group Ⅰ and Group Ⅱ rats was(9.31±1.79) mmol/L and (5.72±0.80) mmol/L respectively,the difference was statistically significant (P<0.05).The blood glucose level of Group Ⅰ rats reached the peak in 3h after injection.In 6-24 h after injection,the blood glucose level of Group Ⅰ A rats was obviously increased than that of the blood glucose level of Group Ⅰa rats and the difference was statistically significant (P<0.05).In 3-24 hours after injection,the blood glucose level of Group Ⅰ B rats was obviously increased than that of the blood glucose level of Group Ⅰ b rats and the difference was statistically significant (P<0.05).Comparing the blood glucose level during different injection time between Group Ⅰ A rats and Group Ⅰ B rats,between Group Ⅰ a rats and Group Ⅰ b rats,the difference was not statistically significant (P>0.05).In 3-24 hours after injection,the blood glucose level of Group Ⅱ A rats was obviously increased than that of the blood glucose level of Group Ⅱ a rats and the difference was statistically significant (P < 0.05);the blood glucose level of Group Ⅱ B rats was obviously increased than that of the blood glucose level of Group Ⅱb rats and the difference was statistically significant (P<0.05).Comparing the blood glucose level during different injection time between Group Ⅱ A rats and Group Ⅱ B rats,between Group Ⅱ a rats and Group Ⅱ b rats,the difference was not statistically significant (P > 0.05).Conclusion Bulbar subconjunctival injection and periocular injection of dexamethasone could both increase the blood glucose of TIDM rats,but these two injection methods had no differences on the blood glucose level.

Objective To investigate the effect of noninvasive ventilator therapy on serum C-reactive protein (CRP), endothelin-1 (ET-1) and tumor necrosis factor-α (TNF-α) levels in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and its clinical significance. Methods One hundred cases of moder-ate and severe OSAHS patients were selected by the method of parallel opening. All of the patients were given health education requirement , quitting smoking and wine , low fat diet and exercise to lose weight and other con-ventional treatment. The patients were randomly divided into the treatment group of 42 cases with noninvasive ventilator treatment , 44 cases treated with conventional treatment , to observe the changes of serum CRP , ET-1 and TNF-α levels and PSG parameters after 12 weeks in two groups. Results Apnea hypopnea index (AHI), oxygen desaturation index (ODI), the lowest oxygen saturation (LSpO2), and the average oxygen saturation MSpO2 in OSAHS patients were significantly improved after treatment (P < 0.01), but the degree of improvement in the two groups after treatment was significantly higher than the control group (P < 0.01). Plasma CRP, ET-1 and TNF-α levels in the two groups after treatment were lower than before treatment (P < 0.05 or P < 0.01), but the treatment group was significantly higher than that of the control group ( P < 0 . 05 or P < 0 . 01 ) . Conclusion Noninvasive ventilator therapy in improving the OSAHS monitoring data of patients with PSG can effectively reduce the serum CRP, TNF-α, ET-1 level, reduce the body′s inflammatory reaction.

Mitochondria DNA was isolated from darkgrown shoots of Xi Feng A according to the procedure reported previously. Mitochondria DNA was digested with EcoR1 completely, and ligated with pUC19 vector DNA which was digested with EcoR1. The ligated DNA was transformed into E. coli JM101. The transformants were selected on LB medium which containing ampicillin 50ug/ml. All of the bacterial clones were hybridized with 32P-labelled maize 26S rRNA gene, seven positive clones were obtained. The plasmid DNAs were isolated from the clones and digested with EcoR1 and southern transferred to NC paper. The membrance was hybridized with maize 26S rRNA probe. One clone which a shortest hybridization band (1.3kb) was named pXMT1.

Objective To investigate the relationship between p62 expression,and occurrence and metastasis of nasopharyngeal carcinomas.Methods Immunohistochemical method was used to analyze p62 expression in 123 nasopharyngeal carcinoma (NPC) cases and 30 chronic nasopharyngitis cases.The clinical pathological characteristics were analyzed.Results The positive rate of p62 protein in chronic nasopharyngitis nasopharyngeal epithelium,non-metastatic NPC tissue,and metastatic NPC tissues was 13.3%,66.67%,and 84.72%,respectively,and the difference was statistically significant.The expression of p62 protein in nasopharyngeal carcinoma patients with lymph node metastasis or distant metastasis was significantly higher than non-metastatic NPC patients (P < 0.01 or P < 0.05).However,the expression of p62 was not related to age,gender,tumor size,and TNM stage (P > 0.05).Conclusions High p62 protein expression in nasopharyngeal carcinoma tissue is closely related to the occurrence and metastasis of nasopharyngeal carcinomas.It provides good reference value to predict NPC malignancy and metastases.

OBJECTIVE:To screen the optimal technology of dog testes and penis processed with talcum powder,and to pro-vide reference for the formulation of quality control standard. METHODS:Taking the comprehensive score of crushing rate and the content of alcohol soluble extract as evaluation indexes,L9(34) orthogonal test was used to optimize processing temperature,pro-cessing time and the amount of talcum powder;validation test was conducted. According to related method in Chinese Pharmaco-poeia(2015 edition),the contents of moisture,ash,nitrogen and alcohol soluble extract were determined,and automatic amino ac-id analyzer was used to determine the content of amino acids in samples. RESULTS:The optimal processing technology were that 100 kg dog testes and penis should add into 40 kg talcum powder;the processing temperature was 350-380 ℃;processing lasted for 4 min. Results of verification test showed that the average crushing rate and the content of alcohol soluble extract were 80.2%(RSD=0.95%,n=3)and 15.7%(RSD=2.30%,n=3). In processed dog testes and penis,the contents of moisture,ash,nitro-gen and alcohol soluble extract were 5.7%,18.7%,8.3%,15.7%,respectively. Besides,there still were 16 kinds of amino ac-ids,and their total content was 42.44%. CONCLUSIONS:The optimized talcum powder processing technology of dog testes and penis is stable and practical. The content of moisture,ash,nitrogen,alcohol soluble extract and amino acid can be used as impor-tant quality standard control indexes for processed dog testes and penis.

OBJECTIVETo study the effects of JTS, Traditional Chinese Medicine caps. treating cerebral ischemia on metabolism and antioxidant system in cerebral ischemia rat.
METHODSI.m. dexamethasone and ligating common carotid artery, the model of cerebral ischemia rats was established to investigate the effects of JTS caps. and its mechanisms through detecting substance metabolism, energy metabolism and antioxidant system.
RESULTSJTS caps. (1.78 - 3.56 g/kg) could upgrade glucose (Glu), total amino acids (T-AA), ATP, Na(+)-K(+) -ATPase, superoxide dismutase (SOD) and catalase (CAT) of brain tissue and degrade lactic acid (LD), malondialdehyde (MDA) and water content of brain tissue in cerebral ischemia rat (P < 0.05, 0.01). JTS caps. (3.56 g/kg) could also depress extenuation of rat's body weight.
CONCLUSIONJTS caps. has some protections against the cerebral ischemia in rats, and one of the mechanisms may be improving the metabolism and antioxidant system.
