80 NSTE-ACS patients were randomly divided into 2 groups: the control group and the therapy group (40 cases in each group). The therapy group was treated with Tirofiban besides the conventional treatment which received by the control group. The level of HIF-1α and hs-CRP was detected immediately, 12, 24, 48 h,and 7 d after hospitalization. The HIF-1αlevel of both group increased in the first 12 hours and then decreased gradually to the baseline in 7 days. The hs-CRP level of both group increased gradually and reached its peak after 24 h after hospitalization, then decreased. Compared with the control group, the level of HIF-1α and hs-CRP decreased sig-nificantly at 12, 24, 48 h and 7 d after hospitalization in the therapy group.

Objective To evaluate the importance of clinical screening and follow up by direct colonoscopy for colorectal cancer at an early and curable stage. Methods There were 2 196 elderly people aged between 60 to 89 years. The clinical screening by direct colonoscopy was performed according to the protocol. 1 740 of 2 196(79.2%) patients were followed up every year. Results Fifty two elderly persons were found to be colorectal cancer patients by colonoscopy, with the detectable rate being 2.4%. Nineteen were diagnosed early stage colorectal cancer, accounting for 36.5% of the detected colorectal cancer. Nine among the followed up cases were detected early colorectal cancer, accounting for 45 0% of the detected colorectal cancer. The resectable rate and the 5 year survival rate was 97 7% and 80 9% for colorectal cancer, respectively. 98 9% of the cecum intubation cases was successful. The incidence of complication for colonoscopy was 0 05%. Conclusions By clincal colonscopy screening and follow up study for colorectal cancer and precancerous changes in the elderly, the patients with adenomatoid polyps were early diagnosed and treated, so it raised the detectable rate of early colorectal cancer and the level of grade prevention of colorectal cancer.

Background Heparanase degrade heparan sulfate side chains of heparan sulfate proteoglycans in the extracellular matrix.Heparanase induces angiogenesis and likely promotes the vascularization of tumor.ObjectiveThe present study is to investigate the expression of heparanase and perlecan in retinas with oxygen-induced retinopathy.Methods Sixty-five clean neonatal C57BL/6J mice were raised in a hyperbaric oxygen box with a volume percentage of 75%±2% for 5 days and then returned to the normal air room.Another 65 matched mice were raised in the normal environment as controls.Evans blue was infused by the superior vena cava in all the mice on postnatal days 12,13,17,21 and 30,afterwards fluorescein angiography was performed and then the mice were sacrificed.The retinas of mice were isolated and prepared and the retinal vessels were examined under a fluorescent microscope and optical microscope.Heranase and perlecan mRNA was detected using reverse transcription PCR (RT-PCR).Heranase and perlecan proteins were detected by Western blot.The analysis of variance was used to compare the mRNA and the protein levels of heranase and perlecan between the experimental and control groups.Results The expression of heparanase mRNA in the retinas of different ages of mice and the different groups showed significant differences (F_(group)=16.303,P=0.000;F_(time)=18.614,P=0.000;F_(interaction)=11.299,P=0.000),and the expression of heparanase mRNA was significantly enhanced in mice from postnatal days 12,13,17 and 21 compared with normal control mice (P=0.001,0.000,0.000,0.001,respectively).The expression of heparanase protein in the retinas of different ages of mice and the different groups followed the same tendency(F_(group)=458.134,P=0.000;F_(time)=78.466,P=0.000;F_(interaction)=71.398,P=0.000).The expression of perlecan mRNA in the retinas of different ages of mice and the different groups showed significant differences (F_(group)=7.351,P=0.013;F_(time)=9.098,P=0.000;F_(interaction)=3.349,P=0.000),and increase in differences also were clearly seen in mice from postnatal days 13,17 and 21 compared with normal control mice (P=0.048,0.000,0.003,respectively).Conclusion The expression of heparanase and perlecan is associated with the development and progression of retinal neovascularization,and perlecan and heparanase together produce a synergistic effect.Heparanase and perlecan may participate in the angiogenesis of oxygen-induced retinopathy.

Objective To evaluate the effect of TGF-β1 and IL-1β expression in serum on acute radiation-induced heart disease (RIHD) in patients with thoracic tumors.Methods Three-dimensional conformal radiotherapy (3D-CRT) or intensity modulated radiotherapy (IMRT) was delivered at 1.8-2.0 Gy,5 times per week to a total dose of 50-66 Gy to 44 patients with lung cancer and 10 patients with esophagus cancer.The target and organs at risk dose distribution were analyzed by 3-dimensiond treatment planning system.The expressions of TGF-β1 and IL-1β in serum were detected by enzyme linked immunosorbent assay before and at the end of the irradiation.The cardiac injury was evaluated by detecting the cmyocardium creatase,cardiac troponin I (cTnI),electrocardiogram and cardiac function before and at the end of the irradiation within 90 d.The acute RIHD was evaluated by the Common Terminology Criteria V 3.0 (NCI-CTCAE 3.0).The expressions of TGF-β1 and IL-1β in the serum of RIHD patients with thoracic tumors were analyzed.Results The expression of TGF-β1 in serum was (888.4 ± 41.1) μg/L before the irradiation and approached to (926.1 ± 23.1) μg/L at the end of the radiotherapy.The expression level of TGF-β1 in the serum of acute RIDH group was (900.6 ± 34.5) μg/L,higher than that of normal group [(865.7 ±47.0) μg/L,t =-2.646,P ＜0.05)].The acute RIDH was correlated with the expression level of TGF-β1 before irradiation and the difference before and at the end of irradiation (r =0.378,0.311,P ＜0.05).The IL-1β expression had no significant difference before and after irradiation.The expression of TGF-β1 in serum before and at the end of irradiation had positive correlation with the expression of IL-1β at the end of the irradiation (r =0.416,0.389,P ＜ 0.05).Conclusions The expression of TGF-β1 in the serum of patients with thoracic tumor increases after irradiation and correlated with the acute RIHD,but the expression of IL-1β in serum has no relationship with RIHD.TGF-β1 could induce the expression of IL-1β at the end of the irradiation.

OBJECTIVETo observe the clinical efficacy of Shugan Yiyang Capsules in the treatment of asthenospermia and its action mechanisms.

METHODSWe randomly assigned 135 asthenospermia patients to groups A (n = 47), B (n = 45), and C (n = 43) to be treated with Shugan Yiyang Capsules, oral levocarnitine, or combination of the two. We observed sperm quality and the level of α-glucosidase in the seminal plasma before and after medication.

RESULTSThe total effectiveness rate was 70.21% in group A (markedly effective in 16 cases and effective in 17), 68.89% in group B (markedly effective in 15 cases and effective in 16), and 83.72% in group C (markedly effective in 16 cases and effective in 20), significantly higher in C than in A and B (P < 0.05). Both sperm quality and the level of α-glucosidase in the seminal plasma were improved in the three groups of patients, most obviously in group C.

Objective To evaluate the indications and intraoperative management of nephron-spar- ing surgery (NSS) for renal cell carcinoma (RCC).Methods A total of 53 patients (32 men and 21 women;age range,21 -76 years) with unilateral RCC and a normal contralateral kidney underwent NSS.The disease course ranged from 1 week to 13 months.The unilateral RCCs were detected by B-uhrasonography. Partial nephrectomy was performed on 38 cases of polar RCC and wedge nephrectomy was performed on 15 cases of central RCC.Both renal vein and artery were blocked for 10 - 15 min,and unclamped for 1 -2 min if necessary.The resections were finished within 7 -21 min (mean,12 min).No inosine and regional hypo- thermia were used during operation.Absorbable hemostatic gauze and terylene flake were used to suture renal wound surface.After operation all patients were treated with interferon hypodermic injection of 5 000 000 U every other day for 3 months.Results The diagnosis of RCC with negative cutting margin was confirmed by pathological examination in all patients.The greatest dimension of the renal cancers were＜4 cm except for one of 6 cm.The clinical stage was T_1N_0M_0 in all patients.During the follow-up of 6 -48 months,all pa- tients were alive without recurrence and had normal renal function.Conclusions NSS can be rapidly per- formed for T_1 stage renal cancer＜4 cm or single clearly localized cancer＞4 cm in diameter.The follow-up results are satisfactory.

Objective: To assess the risk of public health emergencies in Zhejiang Province, March 2021. Methods: An expert counsel was conducted to assess the risk of coronavirus disease 2019 ( COVID-19 ) , enteritis due to norovirus, chicken pox and influenza by professionals in Zhejiang CDC, based on the information from infectious disease and public health emergency surveillance in Zhejiang Province, domestic health administrative departments, World Health Organization, and European CDC. Results: In March 2021, the risk of imported COVID-19 epidemic will be high in Zhejiang Province, and the possibility of local spread could not be ruled out. The possibility of a large-scale outbreak of enteritis due to norovirus and a small-scale outbreak of chickenpox in schools and kindergartens could not be ruled out after the new term begins. An increased risk of influenza epidemic is predicted in collective units such as schools and kindergartens, yet the risk of a large-scale one will be low. Conclusion High attention should be paid to COVID-19 and enteritis due to norovirus, and general attention should be paid to chicken pox and influenza outbreak.

Objective To explore the safety and feasibility of performing total thoracoabdominal aortic aneurysm repair (tTAAAR) under normal thermia and non-cardiopulmonary bypass fashion by comparing surgical indications and details of different surgical strategies in tTAAAR.Methods From February 2009 to May 2011,46 consecutive patients with extensive Crawford Ⅱ thoracoabdominal aortic aneurysm (TAAA)underwent total thoracoabdominal aortic aneurysm repair( tTAAAR ) in An Zhen Hospital.The patients were divided into 2 groups ( A and B) according to their different surgical strategies.Patients in group A underwent total thoracoabdominal aortic aneurysm repair with deep hypothermia and circulatory arrest.Patients in group B underwent total thoracoabdominal aortic aneurysm repair in a normal thermia and non-circulatory bypass was performed via a combined left thoracoabdominal incision.After established the bypass from descending aorta to bilateral iliac arteries under normal thermia,the reestablishment of intercostal arteries and visceral arteries was followed with subsection circulatory arrest.The clinical results of these 2 groups were analyzed by SPSS 18.0.Results Patients in group A underwent total thoracoabdominal aortic aneurysm repair with deep hypothermia and circulatory arrest have higher mortality rate and transient nervous dysfunction rate (26.67％ vs 3.20％,P =0.033 ; 33.30％ vs 3.30％,P =0.018,respectively) than patients in group B underwent total thoracoabdominal aortic aneurysm repair in a normal thermia and non-circulatory bypass.Statistical significance was also observed between group A and circulatory arrest and group B in operation time,descending aortic clamping time,and transfusiori volume of red blood cells ( P ＜ 0.05 ).Average age,sex,pathological type,the maximal diameters of aneurysm,preoperative complications,visceral ischemia time,spinal cord ischemia time,ICU treatment time,intubation time,respiratory complications,plasma dosage,platelets dosage,RBC dosage,thoracotomy hemostatic,spinal cord injury,renal insufficiency were found no statistical significance(P ＞ 0.05 ) between two groups.In addition to death and paraplegia,the others were cured.Conclusion The normal thermia and non-cardiopulmonary bypass tTAAAR is a safe and feasible therapeutic strategy for TAAA patients.A bypass from descending aorta to iliac arteries can be built under normal thermia in TAAA patients,which is the indication of this new technique.Reestablishment of intercostal arteries is an important protective adjunct to avoid spinal cord injury.
