Phosphodiesterase(PDE) is hydrolase of 3',5'-cyclic adenosine monophosphate(cAMP) and 3',5'-cyclic guanosine monophosphate(cGMP).PDE3 are composed of two genes and distributed widely in vivo.Its inhibitors have been applied in antiplatelet aggregation and vasodilation.It has been reported that PDE3 inhibitors have neuroprotective effects on cerebral ischemia,which may provide new methods to prevention and therapy of cerebral ischemia.

Objective To investigate the relationship between with or without non?alcoholic fatty liver disease(NAFLD) and diabetic retinopathy(DR) in type 2 diabetes mellitus(T2DM)?Methods Clinical and laboratorial data of 517 cases T2DM hospitalized patients were collected,and the patients were divided into two groups according to if the NAFLD was complicated or not?Group A was T2DM with NAFLD and group B was T2DM without NAFLD?The general information and the laboratorial checking results were Compared, then various index were used as the independent variable, DR was used as the dependent variable for Logistic regression analysis?Results (1)In the 517 cases of T2DM patients,the incorporative rate of the NAFLD was 65?7%(349/517)?(2)Compared with group B,the levels of body mass index(BMI),insulin resistance index (HOMA?IR),glutamyltransferase(GGT),alanine aminotransferase(ALT),aspartate aminotransferase(AST), triglyceride(TG),total cholesterol(TC),low?density lipoprotein cholesterol(LDL?C) and uric acid(UA) for group A were significantly increased, while the high?density lipoprotein cholesterol ( HDL?C ) level was significantly decreased?All the differences were statistically significant( P<0?05)?( 3) Logistic analysis showed that the duration of the extension,hypertension,the increasing level of NAFLD,LDL?C were the risk factors of DR?Even though excluded the influence of duration,high blood pressure and LDL?C level,NAFLD was still the risk factor for T2DM complicated by the DR( OR=2?176,95% CI ( 1?354,3?199) )?Conclusion NAFLD and DR are closely related, so early diagnosis and intervention of NAFLD may prevent the occurrence and development of DR.

Objective To investigate the effect of normal saline(NS)of different temperature on morphological changes and nitric oxide synthase(NOS)expression of spinal cord.Methods The spinal canal of 96 SD adult rats was opened at T9.which of 24 rats was flushed with 37 ℃ NS,24 with 20 ℃ NS,24 with 4 ℃ NS respectively,and which of 24 rats in control group received no flushing.The spinal canal was closed one hour later,and the spinal cord was taken out 24 hours later.Then the water content in spinal cord was determined by dry-wet method.The morphological changes of spinal cord were observed under light microscope and the electronic microscope.The amount of NOS-positive neuron was measured by ?-NADPH histochemical methods.Results The water content in spinal cord was(66.53?0.61)% in control group,(66.75?1.00)% in 37 ℃ group,(70.55?0.77)% in 20 ℃ group,(71.92?2.50)% in 4 ℃ group.The spinal cord of control group and 37 ℃ group contained less water than that of 20 ℃ group and 4 ℃ group.There were no obvious morphological changes in the control group and 37 ℃ group.In 20 ℃ and 4 ℃ groups,the demyelination of axon,swelling of cell body and the disappearance of tigroid body were observed under light microscope,the partial disaggregation of medullary sheath,swelling of mitochondria and disappearance of mitochondria crista could be observed under electron microscope.The amount of NOS-positive neuron in spinal cord was(18.75?2.12),(18.63?1.41),(14.75?1.67),(8.13?1.25)in control,37 ℃,20 ℃ and 4 ℃ groups,respectively.The control group and 37 ℃ group showed more NOS-positive neuron than those of 20 ℃ group and 4 ℃ group.Conclusion NS below 20 ℃ can injury spinal cord.It is suitable to choose 37 ℃ NS to flush brain and spinal card during operation.

Objective Using video tracking system to compare the effects of the locomotor activity between theophylline and caffeine in mice.Methods The KM mice were treated by theophylline and caffeine(both at 1,3,10,30,100 mg/kg)intraperitoneally respectively.After 10 min,the locomotor activity in the open field was recorded for 2 hours.The locomotor track,the total distance,the distances and distance ratio to total distance in central region were analyzed to evaluate the effects of these drugs on locomotor in mice.Results The mice administrated theophylline and caffeine both increased the total distances,and had similar bell-shaped dose-effect relationship.The distances reached the highest at 30 mg/kg theophylline((311±128)m)and 10 mg/kg caffeine ((279±89)m).The larger doses of caffeine inhibited the activity,and the total distance during 0～0.5 h was significantly decreased at the dose of 100 mg/kg(P＜0.05).Theophylline(30 and 100 mg/kg)and caffeine (30 mg/kg)significantly increased the distance ratio in central region(P＜0.01)and decreased the distance ratio in peripheral region(P＜0.01).Conclusion Theophylline and caffeine increase the total distance and the distance ratio in central region in mice,but have different valency and efficacy.

Aim To investigate the protective effect of flavonoids from Radix tetrastigmae (RTFs)on lipopo-lysaccharide (LPS)induced acute lung injury (ALI) of aged mice and the mechanism.Methods Aged C57BL/6J mice were bronchially instillated LPS to in-duce ALI.RTFs were orally administered to treat ALI. After 3 days,bronchoalveolar lavage fluid (BALF) was collected to enumerate leukocytes with Wright-Gi-emsa staining,and to detect inflammatory cytokines with ELISA.ELISA and Western blot methods were al-so used to detect the expression of MAPKs and NF-κB in lung tissues.The activity of NF-κB in nucleic pro-tein extract was detected with TransAMkit.Results
ALI models were successfully induced through LPS in-stillation.RTFs significantly reduced leukocyte,espe-cially neutrophil infiltration in BALF,inhibited IL-1 β, IL-6,IL-1 2p40,TNF-αand sTNF-R1 secretion,and improved pathohistological change of lung tissues.Be-sides,RTFs significantly attenuated the phosphoryla-tion of p38MAPK,NF-κB and the activity of NF-κB. Conclusion RTFs inhibits LPS-induced ALI through p38MAPK and NF-κB pathway and exhibits significant anti-inflammation effect on aged mice.

ObjectiveTo to evaluate the effects of nimodipine on cerebrovascular function in subarachnoid hemorrhage(SAH) using cerebrovascular hemodynamic indexes (CVAI),and to study the clinical value of CVAI in the dosing of nimodipine after SAH.Methods58 patients with SAH were given nimodipine 0.25 μg/kg·min by intravenous drip(i.v) after admitted to hospital. CVAI and NIHSS were examind before and 1 d, 7 d, 14 d after intravenous. ResultsNimodipine improved cerebrovascular function significantly, including increasing cerebral blood velocity and flow, decreasing cerebrovascular resistance(R) and critical pressure(CP). For those patients with NIHSS worse and R value increased, increased dosing could decrease cerebrovascular resistance(P<0.05) and improve neurological function significantly(P<0.05). ConclusionIndividualization is necessary in dosing of nimodipine treatment of SAH. R value is a important index in adjusting the dose of nimodipine.

Objective: To understand the mortality and probability of premature death due to malignant tumors, cardio-cerebrovascular diseases, diabetes and chronic respiratory diseases in Taizhou City, Zhejiang Province, so as to provide the basis for the improvement of chronic diseases prevention and control strategies. Methods: The death data of the four chronic diseases among local residents in Taizhou City from 2019 to 2022 were collected through Taizhou Chronic Disease Information Management System, and the crude mortality, standardized mortality (standardized by the data of the seventh national population census in 2020) and probability of premature death were calculated. The trends in mortality and probability of premature death were analyzed using annual percent change (APC). The attainment of probability of premature death due to the four chronic diseases were evaluated using the target values and predicted values in 2025 and 2030. Results: There were 119 899 deaths from the four chronic diseases in Taizhou City from 2019 to 2022, with the crude mortality of 494.48/105 and the standardized mortality of 410.68/105, which was no significant changing trend (APC=4.680% and -2.795%, both P>0.05). The probability of premature death decreased from 10.39% to 8.69% (APC=-6.027%, P<0.05). The crude mortality and standardized mortality in males were higher than those in females (562.13/105 vs. 424.08/105; 461.67/105 vs. 353.81/105; both P<0.05). The crude mortality and standardized mortality in rural areas were higher than those in urban areas (499.65/105 vs. 480.52/105; 429.20/105 vs. 365.68/105; both P<0.05). The probability of premature death in women and rural residents showed downward trends (APC=-8.210% and -7.558%, both P<0.05) from 2019 to 2022. The standardized mortality and probability of premature death due to malignant tumors showed downward trends (APC=-6.090% and -8.019%, both P<0.05). The crude mortality of diabetes showed an upward trend (APC=18.654%, P<0.05). The predicted values for probability of premature death due to due to the four chronic diseases in 2025 and 2030 were 7.27% and 5.40%, respectively, and were lower than the target values of 10.02% and 8.77%. Conclusions From 2019 to 2022, there was no significant trends in the mortality of four chronic diseases in Taizhou City, with rural men being the key population for prevention and control. The probability of premature death showed a downward trend, and it was expected to achieve the target in 2025 and 2030.

OBJECTIVE: To determine the efficacy and safety of early intervention with nimodipine treatment in diffuse axonal injury. METHODS: Based on the characteristic radiological signs and criteria for diffuse axonal injury (DAI), 89 patients with the diagnosis of DAI were enrolled in this randomized, double-blind, placebo-controlled trial. RESULTS: Nimodipine proved to be safe and well tolerated. With TCD sonography we found that there was a higher incidence of cerebral vasospasm in this series (38.2%). Overall, Nimodipine produced a better clinical result than placebo, but there was no statistically significant difference in favorable outcome at 3 months after injury (P=0.11) between the two groups. A trend toward a favorable effect was suggested by the analyses in two small subgroups, either in the patients suffering from clinical Grade III DAI (P=0.04), or in those with the TCD-evidence of cerebral vasospasm during clinical observation (P=0.049). CONCLUSIONS: We postulate that a clinically valuable benefit is possible with nimodipine treatment in DAI patients. However, the effects on outcome should be verified by further controlled study.
