AIM: To observe the clinical efficacy of adjunctive intravitreous injection with Lucentis for the treatment of neovascular glaucoma ( NVG) .
METHODS:The retrospective case series study included 25 eyes of 25 patients who underwentintravitreous injection with Lucentis. Patients firstly received an intravitreous injection with Lucentis (0. 5mg/0. 05mL), after the regression of neovascularization of the iris, patients accepted different surgical treatments according to different etiopathogenesis condition. Iris, chamber angle neovascularization condition, intraocular pressure, and visual acuity were observed postoperatively. The follow-up duration was 3mo.
RESULTS:After 3-7d of intravitreous Lucentis injecting, iris and chamber angle neovascularization was totally faded in 20 cases (20 eyes) and was not completely faded in 5 cases ( 5 eyes ) . Additional treatments were compound trabeculectomy ( 14 cases, 14 eyes ) , vitrectomy ( 4 cases, 4 eyes ) . The patients' mean intraocular pressure was 43. 42 ± 10. 99mmHg before treatment, which decreased rapidly when they came out of the hospital (14. 26±7. 64mmHg, P<0. 05) and stabilized during the follow-up 3mo (18. 76±5. 96mmHg, P<0. 05). Follow-up at 3mo, visual acuity improved or remained in 20 cases ( 20 eyes ) and decreased in 5 cases ( 5 eyes ) . The complete success, qualified success and failure were 21 eyes, 3 eyes and 1 eye, respectively.
CONCLUSION:Intravitreous injection with Lucentis can be used as an assisted treatment of NVG. According to different etiopathogenesis condition, it is an effective treatment to combine with other treatment methods for NVG.

OBJECTIVETo explore the effects of stromal interaction molecule 1 (STIM1) on the expression of apoptosis-related proteins in prostate cancer PC-3 cells.

METHODSWe transfected the lentivirus vector STIM1-pGCSIL-GFP carrying STIM shRNA into human hormone-independent prostate cancer PC-3 cells, and 3 days later observed the transfection efficiency by fluorescence microscopy. At 7 days after transfection, we determined the expression of STIM1 in the PC-3 cells by RT-PCR and Western blot and those of apoptosis-related proteins Bcl-2, Bax, survivin and activated Caspase-3 by Western blot.

RESULTSAt 3 days, inverted microscopy revealed a transfection efficiency of > 80%. At 7 days, the STIM1 expression was significantly inhibited at both mRNA and protein levels. The Bcl-2/Bax rate was remarkably decreased as compared with that of the control group (0. 31 vs 1.24 ) , and the survivin expression was markedly reduced, 0. 14 times that of the relative expression in the control. However, the Caspase-3 cleavage was significantly activated, 1.52 times that of the control (P <0.05).

CONCLUSIONSTIM1 can be regarded as an oncogene in prostate cancer PC-3 cells. Inhibition of its expression can induce PC-3 cell apoptosis by reducing the Bcl-2/Bax rate, decreasing the survivin expression, and activating the Caspase-3 pathway.

OBJECTIVETo explore the characteristics of distribution of pulse pressure (PP) in Chinese population and its relationship to major cardiovascular diseases in them.

METHODSData from the Third National Blood Pressure Survey involved 882,681 subjects aged over 18 in 1991 were reanalysed for the relationship between PP and risks of major cardiovascular diseases, with t-test, chi2 test and logistic regression model. PP is defined as the difference between systolic and diastolic blood pressure.

RESULTS(1) Overall mean PP was (44.61 +/- 13.59) mm Hg for the subjects aged over 18, higher in men [(44.92 +/- 12.72) mmHg] than that in women [(44.34 +/- 14.32) mmHg]. PP increased progressively with age, and its increase accelerated significantly at age over 50 but higher in women than in men. Proportion of the subjects with PP equal to or greater than 60 mmHg was more in those aged 60 or over than that in younger ones. (2) Prevalence of stroke and myocardial infarction (MI) increased with PP and age, whether in the normotensives, or in the hypertensives or in the isolated systolic hypertensives. (3) Results of multivariate logistic regression analysis revealed that risks of stroke in the subjects with PP of (45-59) mmHg, (60-74) mmHg and over 75 mmHg were 1.9, 3.5 and 5 times as in those with PP less than 45 mm Hg, respectively, adjusted for other risk factors, and their risks of myocardial infarction (MI) were 1.2, 1.5 and 1.7 times, respectively. Furthermore, PP was significantly and independently related to the risks of stroke and MI, even adjusted for systolic and diastolic pressures.

CONCLUSIONSPrevalence of stroke and MI increased with the breadth of PP and age. Broader PP may be an important and independent predictor of risks of stroke and MI, especially in the aged people.

OBJECTIVETo elucidate the relationship between surgical time and postoperative complications in senile patients with hip fractures, and try to find out other factors which are related to these complications.

METHODSSixty-two patients, 28 males aged from 65 to 72 years with a mean age of 76.3 years and 34 females aged from 65 to 95 years with a mean age of 78.1 years, who had undergone orthopedic surgery because of hip fractures, were enrolled in a retrospective cohort study. The surgical time and pattern, the type of fracture, preoperative comorbidities, American Society of Anesthesiologists (ASA) score and the volume of blood transfusion during operation were obtained from these patients who were followed up by telephone calls for postoperative complications. All the patients were followed up at least for 1 year and were divided into subgroups according to their clinical characteristics and the results were analyzed by the Statistical Analysis System software.

RESULTSThere was no significant difference in the morbidity of postoperative complications with the gender, age, surgical time and pattern, or ASA score. There was significant difference in the morbidity of postoperative complications related to preoperative comorbidities and the volume of blood transfusion. There was a significant causality between preoperative comorbidities and postoperative complications. The morbidity of postoperative complications was 1.651 times higher in patients with preoperative comorbidities than those without.

CONCLUSIONSThere is no relationship between the surgical time and postoperative complications in senile patients who received surgery for hip fracture within 1 year. No correlation is found between the postoperative complications and gender, age, type of fracture, surgical pattern, ASA score and the volume of blood transfusion. Preoperative comorbidities are an independent predictor for postoperative complications.

Objective To investigate the effects of Tangshen Formula on liver oxidative stress in diabetic rats, and their mechanisms thereof.Methods Rat model of type 2 diabetes mellitus and nonalcoholic fatty liver disease was estab?lished by intraperitoneally injecting small dose of chain urea with cephalosporins (STZ) and feeding high fat fodder . The model rats were randomly divided into control group, model group, Tangshen Formula group and metformin group.The se?rum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), cholesterol (CHO), low density lipoprotein-cholesterol(LDL-C), and superoxide dismutase (SOD), catalase(CAT), vitamin E(VE), nitric oxide (NO) and nitric oxide synthase (NOS) in liver were compared between four groups. Changes of pathological morphology were ob?served under light microscopy. Results There were significantly decrease in serum levels of ALT, AST, TG, CHO, LDL-C in Tangshen Formula group and metformin group compared with those of model group. There were significantly higher levels of SOD, CAT and VE, and lower levels of NO and NOS of liver homogenate in Tangshen Formula group than those of model group. There were higher levels of SOD and CAT, and lower levels of NO and NOS in liver homogenate in metformin group than those of model group. HE staining showed that liver fatty degeneration was significantly reduced in metformin group and Tangshen Formula group compared with that of model group. Conclusion The fatty liver in type 2 diabetic rats is signifi?cantly improved by Tangshen Formula treatment, which is probably associated with the regulation of the response level to oxi?dative stress in liver.

OBJECTIVETo explore the association of serum HBV DNA level with HBV-specific and nonspecific cytotoxic T lymphocytes (CTL) in patients with HBV-induced hepatic cirrhosis.

METHODS120 patients with HBV-induced hepatic cirrhosis who were positive for HBV DNA, HBeAg and human leucocyte antigen (HLA)-A2 were enrolled in this study. The level of HBV DNA was determined by real time fluorescence quantitative polymerase chain reaction (PCR). HBV-specific and nonspecific CTL were detected by flow cytometry. Liver function tests were done in the 120 patients. The 120 patients were divided into group A and B based on their HBV DNA levels. In group A, there were 68 patients with HBV DNA level of 3-4 log10 copy/ml, and in group B, 52 with 5-6 log10 copy/ml. HBV-specific and nonspecific CTL and liver function were compared between the two groups.

RESULTSHBV DNA levels were (3.68 +/- 0.19) and (5.97 +/- 0.32) log10 copy/ml in Group A and B respectively with P < 0.001. HBV-specific CTL was higher in group A (0.33% +/- 0.04%) than in group B (0.11% +/- 0.01%) with P < 0.001. HBV-nonspecific CTL were (11.99% +/- 1.51% ) and (11.91% +/- 1.61%) in group A and B respectively with P > 0. 05.

CONCLUSIONThe level of serum HBV DNA is related to the levels of HBV-specific CTL in patients with HBV-induced hepatic cirrhosis. Patients with higher HBV DNA had lower levels of HBV-specific CTL, and the damage to liver function was severe because of higher levels of HBV DNA. Patients with lower HBV DNA had higher levels of HBV-specific CTL which predict good anti-viral effect.

OBJECTIVETo explore relationship between HBV DNA level and peripheral blood follicular helper T lymphocyte (Tfh) in patients with chronic hepatitis B (CHB) and its significance.

METHODSHBV DNA levels of 179 cases of CHB patients with positive HBV DNA, positive HBeAg and positive human leukocyte antigen(HLA)-A2 were tested with real time fluorescent quantitative PCR. Tfh and HBV specific CTL were tested with flow cytometry. IL-21 was also tested. 179 cases of CHB patients were divided into group A and group B based on HBV DNA levels, 86 cases in group A, HBV DNA levels were 10(4)-10(5) copies/ml, 93 cases in group B, HBV DNA levels were 10(6)-10(7) copies/ml. Above testing indexes of the two groups were compared.

RESULTSHBV DNA levels of group A were (4.85 +/- 0.37) log10 copies/ml, HBV DNA levels of group B were (6.83 +/- 0.31 ) log10 copies/ml, t = 27.31, P < 0. 001; Tfh of group A was (5.96 +/- 1.59)%, higher than that of group B (3.71 +/- 2.15)%, t = 4.92, P < 0.01; IL-21 of group A was (42.61 +/- 15.11)ng/L, higher than that of group B (14.91 +/- 3.15) ng/L, t = 8.62, P < 0.01; HBV specific CTL of group A was (0.36 +/- 0.08)%, higher than that of group B (0.18 +/- 0.06)%, t = 19.99, P < 0.001.

CONCLUSIONSerum HBV DNA level of CHB patients is related to the level of peripheral blood Tfh level: patients with low HBV DNA level have high Tfh level, high IL-21 level and high HBV specific CTL level. Patients with high HBV DNA level have low Tfh level, low IL-21 level and low HBV specific CTL level. The mechanism of baseline HBV DNA level affecting anti-viral therapy may be related to Tfh level.

OBJECTIVETo explore influence of sodium restricted diet and non-sodium restricted diet on plasma rennin (PRA), angiotensin II (All), ALD, renal blood flow (RBF) and subside of ascites in patients with cirrhotic ascites.

METHODSEighty cases of hepatitis B with cirrhotic ascites were randomly divided into sodium restricted diet group and non-sodium restricted diet group. 39 cases were in non-sodium restricted diet group, taking sodium chloride 6500-8000 mg daily; 41 cases were in sodium restricted diet group, taking sodium chloride 5000 mg daily. Both groups received diuretics furosemide and spironolactone. Blood sodium, urine sodium, PRA, AII, ALD, RBF ascites subsiding were compared after treatment.

RESULTSIn non-sodium restricted diet group, blood sodium and urine sodium increased 10 days after treatment compared with those before treatment, and compared with those of sodium restricted diet group 10 days after treatment, P <0. 01. RBF increased compared with that before treatment, and compared with that of sodium restricted diet group 10 days after treatment, P < 0. 01. Renal damage induced by low blood sodium after treatment was less in non-sodium restricted diet group than that in sodium restricted diet group, P <0. 05. Ascites disappearance upon discharge was more in sodium restricted diet group than that in non-sodium restricted diet group, P <0. 01. Time of ascites disappearance was shorter in non-sodium restricted diet group than that in sodium restricted diet group, P < 0. 01.

CONCLUSIONCompared with sodium restricted diet, while using diuretics of both groups, non-sodium restricted diet can increase level of blood sodium, thus increasing excretion of urine sodium and diuretic effect. It can also decrease levels of PRA, AII and ALD, increase renal blood flow and prevent renal damage induced by low blood sodium and facilitate subsiding of ascites.
