AIM:To observe the efficacy of intravitreal conbercept injection for chronic central serous chorioretinopathy (CSC).METHODS: Nine eyes of 9 patients diagnosed as chronic CSC between October 2015 to May 2016 were treated with an intravitreal injection of conbercept (0.5mg/0.05mL) (six patients were given the same does of intravitreal injection again at 1mo after the first injection).Follow-up observation was at 1, 2, and 6mo after injection.Observed indicators included best-corrected visual acuity (BCVA), intraocular pressure, optical coherence tomography (OCT), fundus fluorescein angiography (FFA), choroidal indocyanine green angiography (ICGA), macular fovea thickness (CMT), subfoveal choroidal thickness (SFCT).RESULTS:Seven of the 9 patients responded significantly to the drug, while 2 patients had no response.The CMT was 373.12±72.43μm at baseline, which decreased significantly to 332.05±67.13μm, 282.24±62.30μm and 225.56±71.08μm at 1, 2 and 6mo after the intravitreal injection.The mean thickness of SFCT was 422.11±64.82μm before treatment.The choroidal thickness of non-responsive patients before treatment was below average, respectively 353μm and 365μm.The SFCT of 1, 2, and 6mo after treatment was 391.45±75.24μm, 365.53±63.07μm, 355.40±66.65μm.Before treatment and 1mo after, there was no significant difference (P=0.074), but there was statistically significant (P<0.01) between those of before and 2mo and 6mo after.The mean BCVA of the prior treatment was 0.53±0.32, the after treatment was 0.65±0.20, there was no different between the two(P>0.05).CONCLUSION: Intravitreal conbercept injection in chronic CSC may have some effect in accelerating subertinal fluid resolution and decreasing the CMT.The SFCT within 6mo after treatment was significantly lower than pretreatment.The SFCT may be an indicator of whether patients respond.

Partial nature of "promoting blood circulation and dieresis" of Salvia Miltiorrhizain was initially demonstrated by investigating the regulation effect of AQP2 expression in kidney of trauma blood stasis model rats with the Salvia Miltiorrhizain so as to provide guidance for its clinical deployment of administration. Random allocation was taken to averagely divide 30 SD rats into two groups: 10 rats in normal group and 20 rats in blood stasis syndrome group. Trauma blood stasis rat model was established by quantitatively beating. Then the rat model group was divided into model group and salvia group. After 7 days of treatment, the rat kidney AQP2 expression was detected, the content of urine AQP2 was compared and the damaged local muscle and kidney pathological changes were observed by immunohistochemical method and western blot method. Compared with that of the normal group, rats in model group had inflammatory cells infiltration, blood stasis and edema of the injured local muscles and up-regulated AQP2 expression, decreasing urinary output, and kidney tissues blood stasis and edema (P < 0.05). On the other hand, compared with that of the model group, those parameters of rats in salvia group were all decreasing except urine output (P < 0.05). Such result indicated that Salvia Miltiorrhiza can reduce trauma blood stasis rat content of urine AQP2 and down-regulated AQP2 expression in kidney tissue, so as to reduce the reabsorption of water by renal tubular and increase urine output. The promoting blood circulation effect of Salvia Miltiorrhizain can alleviate the degree of the damaged tissue edema and encourage urine drainage. This therapy is closely related to the effect of regulating AQP2 in kidney by salvia, so the purpose of this study by verifying "promoting blood circulation and diuresis" as the mechanism for the regulation effect of the salvia on AQP2 expression.

OBJECTIVETo explore an optimal anesthesia method with less impact on hemodynamics and electrocardiogram (ECG) of old patients with coronary artery disease (CHD) during abdominal operation.

METHODSThe 133 CHD patients waiting for abdominal operation were randomly divided into continuous epidural anesthesia (EA) group, general anesthesia group (GA) and combined spinal-epidural anesthesia (CSEA) group. Continuous monitoring was carried out during operation and mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SaO2), abnormal ECG were measured respectively at different time for comparison and the differences of the above hemodynamic parameters and abnormal ECG features were compared among the 3 groups.

RESULTSAt the 15 min and 30 min point after anesthesia, SaO2 in GA group was significantly increased compared to that in the EA group (P < 0.05). At 15 min, 30 min and 60 min point after anesthesia, MAP in CSEA group was significantly increased compared to that in the EA group (P < 0.05). At 30 min point after anesthesia, HR in CSEA group was increased significantly compared to the EA group (P < 0.05). At 15 min and 30 min point after anesthesia, SaO2 in the CSEA group was increased significantly compare to the EA group (P < 0.05). Compared with preanesthesia (T0) in EA group, MAP, HR and SaO2 decreased significantly at 15, 30 and 60 min after anesthesia (P < 0.05). The fluctuation of the three parameters in GA and CSEA groups were relatively small (P > 0.05). As well as the comparison of abnormal ECG among the 3 groups was concerned, the incidence of ST-T changes in GA and CSEA groups were significantly lower than that in EA group at the time of 15 min, 30 min and 60 min after anesthesia and at the time of surgery termination (P < 0.05, P < 0.01). The incidence of arrhythmia in GA and CSEA groups were significantly lower than that in EA group at the time of 15 min, 30 min and 60 min after anesthesia (P < 0.05, P < 0.01). Compared with T0 in the same group, the incidences of ST-T changes and arrhythmia in GA or CSEA group at the time of 15, 30 and 60 min after anesthesia and at the time of surgery termination were significantly lower than that before anesthesia (P < 0.05, P < 0.01).

CONCLUSIONGA and CSEA have less impact on hemodynamics and have smaller incidence of abnormal ECG of old CHD patients with abdominal operation.

OBJECTIVETo build a type 2 diabetes mellitus rat model with cardiac ischemia.

METHODSMale Wistar rats were fed high sucrose and high fat diet for four weeks and then injected with streptozoticin (STZ) (40 mg/kg .i.p.). The levels of fasting blood glucose and serum insulin were monitored every week. The body weights of rats were also measured every week. The blood levels of creatine kinase and lactate dehydrogenase (LDH) were measured following the electrocardiograph used BL-410 biological experiment system.

RESULTSThe serum insulin levels of diabetic rats were 4.05 ng/ml after four weeks high sucrose and high fat diet. The fasting blood glucose levels of diabetic rats were 17.9 mmol/L after injection. Compared with normal group, there was obvious change of S-T segment in the electrocardiograph of diabetic group at the fourteenth week. The levels of creatine kinase and lactate dehydrogenase in diabetic group significantly increased in comparison with those in normal group.

CONCLUSIONThe cardiac ischemia of diabetic rats model is suitable for investigating cardiac disease of diabetes mellitus.

The paper aimed to evaluate the effects of lead stress on photosynthetic performance and ginsenoside content in ginseng (Panax ginseng). To accomplish this, three years old ginseng were cultivated in pot and in phytotron with different concentrations of lead, ranging from 0 to 1000 mg x kg(-1) soil for a whole growth period (about 150 days). The photosynthetic parameters in leaves and ginsenoside content in roots of ginseng were determined in green fruit stage and before withering stage, respectively. In comparison with the control, net photosynthetic rate and SPAD value in ginseng leaves cultivated with 100 and 250 mg x kg(-1) of lead changed insignificantly, however, ginseng supplied with 500 and 1 000 mg x kg(-1) of lead showed a noticeably decline in the net rate of photosynthesis and SPAD value (P < 0.05), the lowest net photosynthetic rate and SPAD value showed in the treatment supplied with 1 000 mg x kg(-1) of lead, with decline of 57.8%,11.0%, respectively. Total content of ginsenoside in ginseng roots cultivated with 100 mg x kg(-1) of lead showed insignificantly change compared to the control, but the content increased remarkably in treatments supplied with 250, 500, 1 000 mg x kg(-1) of lead (P < 0.05), and highest content appeared in these ginsengs exposed to 1000 mg x kg(-1) of lead. The net photosynthetic rate and SPAD value in leaves of ginseng both showed significantly negative linear correlations with lead stress level (P < 0.01), and significant positive linear correlations between total content of ginsenoside and lead concentration was also observed (P < 0.05). These results strongly indicate that exposing to high level of lead negatively affects photosynthetic performance in ginseng leaves, but benefits for accumulation of secondary metabolism (total content of ginsenoside) in ginseng root.

Objective To explore the expression of TLR4/NF-κB pathway in cerebral injury resulting from DHCA ( deep hypothermia circulatory arrest ) as well as the effect of SACP ( selective antegrade cerebral perfusion). Methods Twelve pigs were randomly assigned to DHCA group (n = 6) or SACP group (n = 6) at 18 ℃ for 80 min. IL-6 was assayed by ELISA. Apoptosis and NF-κB proteins were detected by fluorescence TUNEL and Western blot, respectively. The level of TLR4 was determined through qRT-PCR and Western blot. Results Serum IL-6 level of SACP group was significantly lower at the end of circulation arrest and experiment and apoptotic index and NF-κB protein were apparently lower in SACP group (P < 0.05). The level of TLR4 protein and mRNA from SACP group decreased significantly (P < 0.05). Conclusions TLR4/NF-κB pathway plays a critical role in pathogenesis of DHCA cerebral injury and attenuating TLR4/NF-κB cytokines probably contributes to neuroprotection of SACP. TLR4/NF-κB pathway may be a novel target for DHCA.
