OBJECTIVETo explore the perioperative cardiovascular dysfunction and its relevance to age in patients with silent coronary heart disease (or silent myocardial ischemia), and explore the clinical treatment and recovery of perioperative arrhythmias.

METHODSOne hundred and eighty cases were selected from selective surgery patients with silent myocardial ischemia (SMI). Among the cases, 130 patients older than 51 years old were divided into 51 - 60 year-old group, 61- 70 year-old group and 71 - 80 year-old group. Control group was set up by other 50 patients younger than 51 years old. Electrocardiogram data of 24 h before the operation, 24 h after the operation and 48 h after the operation were continuously monitored by dynamic electrocardiogram (DCG). The electrocardiogram data of ST shifting, arrhythmia incidences of different type and at different time were analyzed by professional doctors. At the same time, the treatment and recovery of perioperative arrhythmia were recorded.

RESULTSAs the age increase, the magnitude and duration of ST shifting appeared upward trend compared to the control group (P < 0.05, P < 0.01). The incidence of ST elevation in 71 - 80 year-old group was higher than the control group (P < 0.05). The ST depression duration in 61 - 70 and 71 - 80 year-old group and ST elevation magnitude in 71 - 80 year-old group were higher than 51 - 60 year-old group (P < 0.05). Compared to the control group, the incidence of accelerated idioventricular rhythm (AIR) in 61 - 70 year-old group and the incidence of sinus bradycardia (SB), ventricular premature beat (VPB), ventricular tachycardia (VT) in 71 - 80 year-old group were higher (P < 0.05, P < 0.01). Compared to the 51 - 60 year-old group, the incidence of atrial fibrillation (AF) in 61 - 70 year-old group and the incidence of VP, VT, AF in 71 - 80 year-old group were higher (P < 0.05, P < 0.01). The arrhythmia incidences in 24 h after operation were higher than 48 h after operation and 24 h before operation (P < 0.01). As the age increase, the recovery incidence by removing inducement was decreased, but the recovery incidences by drug and electric-shock treatment were increased (P < 0.05).

CONCLUSIONOld SMI patients have high levels of perioperative myocardial ischemia and arrhythmia, and 24 h after operation is the period of high incidence.

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 study the inhibitory effect and reasons of liposomes survivin antisense oligonucleotides (ASODN) on growth of human gastric carcinoma transplanted subcutaneously in nude mice.

METHODSHuman gastric carcinoma transplanted subcutaneously in nude mice model was established, and subsequently was divided randomly into six groups: control group, liposome group, sense oligonucleotide (SODN) group, 100, 200 and 400 nmol/L ASODN group. Different treatments were given respectively. The weight and volume of subcutaneous tumors were measured, and tumor growth inhibitory rate and decreased rate was calculated. The morphological changes of transplanted tumor cells were observed under light microscope. The expression of survivin was detected by immunohistology (SP). Changes of survivin gene transcription and protein expression were determined by western blot and RT-PCR.

RESULTSGrowth of the tumors was significantly inhibited in all ASODN groups as compared with that in the control, liposome and SODN group. The highest growth inhibitory rate in the 400 nmol/L group is 93%. The number of apoptotic cells of ASODN group increased and expression of survivin became weaken under the microscope. Liquified necrosis regions could be seen in 6 cases (6/12) of tumor tissues. The content of survivin mRNA and protein decreased in all survivin ASODN groups. The survivin protein expression of 400 nmol/L group was about 36.8% of the control group.

CONCLUSIONSSurvivin gene ASODN can inhibit the growth of human gastric carcinoma in nude mice by inducing cells apoptosis and decreasing the expression of survivin mRNA and protein.

OBJECTIVETo investigate the inhibitory effect and mechanism against the growth of human gastric carcinoma cell line HS-746T by the combination of the survivin antisense oligonucleotide (ASODN) and P53 gene and its mechanism.

METHODSGastric carcinoma cell line HS-746T was treated by P53 gene and survivin antisense oligonucleotide was designed. There were four regimen groups treated by different agents:ASODN alone, P53 gene alone and the combination of ASODN and P53 gene, blank control. Cell proliferative ability and cell growth were determined by cells counting and MTT. The expression of survivin mRNA and protein was detected by RT-PCR and Western blot respectively. Cell apoptotic index was detected by TUNEL.

RESULTSASODN alone, P53 alone and the combination of ASODN and P53 could inhibit not only the growth of gastric carcinoma cell, but also down-regulate the survivin mRNA and protein expression. The inhibitory effect was stronger, and the apoptosis index was higher in the combined transfection group than those in the other two single transfection groups.

CONCLUSIONThe combination of survivin ASODN and P53 gene is more efficient to inhibit cell growth and induce apoptosis than that of agent alone.

AIM: To investigate the curative effect of phacoemulsification and intraocular lens ( IOL ) implantation combined with goniosynechialysis in the treatment of age-related cataract merging with primary angle-closure glaucoma ( PACG) . · METHODS: Totally 80 patients with age-related cataract merging with PACG were in our hospital from January 2014 to January 2016. The preoperative average intraocular pressure ( IOP) was 33. 22 ± 3. 17mmHg; the average depth of anterior chamber was 2. 07 ± 0. 15mm;the dynamic situation of primary angle closure ≤1/2 cycle by gonioscope. They were randomly divided into Group A and B for doing a study. All the two groups were treated with phacoemulsification and intraocular lens implantation. And the Group A was with goniosynechialysis. The following up period was 2mo, and we observed the IOP, chamber depth and the anterior chamber angle. · RESULTS: The change of chamber depth and intraocular pressure about the two groups: the average intraocular pressure of the Group A was 15. 11 ± 3. 67mmHg,the chamber depth was 3. 11±0. 08mm;those of the Group B were 17. 24 ± 1. 67mmHg, 2. 76 ± 0. 15mm respectively; the differences had statistical significance (P<0. 05). Postoperatively, there were 28 eyes (70%) in Group A with fully open anterior chamber angle, and 18 eyes (45%) in Group B (P<0. 05). · CONCLUSION: The phacoemulsification and intraocular lens implantation combined with goniosynechialysis in the treatment of age-related cataract merging with primary angle-dosure glaucoma is safe and reliable. It's simple to operate, and do not increase the risk of surgery.

Field experiments were conducted in farmers' rice fields in 2001 and 2002 to study the effects of nitrogen (N) management strategies on N use efficiency in recovery (RE), agronomy (AE) and physiology (PE) and redistribution of dry matter accumulation (DMA) and nitrogen accumulation (NA) in two typical rice cultivars in Jinhua, Zhejiang Province. This study aimed mainly at identifying the possible causes of poor fertilizer N use efficiency (NUE) of rice in Zhejiang by comparing farmers' fertilizer practice (FFP) with advanced site-specific nutrient management (SSNM) and real-time N management (RTNM). The results showed that compared to FFP, SSNM and RTNM reduced DMA and NA before panicle initiation and increased DMA and NA at post-flowering. There is no significant difference between SSNM and FFP in post-flowering dry matter redistribution (post-DMR) and post-flowering nitrogen redistribution (post-NR). These results suggest that high input rate of fertilizer N and improper fertilizer N timing are the main factors causing low NUE of irrigated rice in the farmer's routine practice of Zhejiang. With SSNM, about 15% of the current total N input in direct-seeding early rice and 45% in single rice could be reduced without yield loss in Zhejiang, China.
