Malnutrition is common in the abdominal surgery and affects the recovery of patients.Reasonable nutritional support therapy can improve the prognosis of patients.The nutritional risk screening should be apphed to patients within 24 hours of admission.Patients with the nutritional risk and malnutrition should receive the nutritional support by selecting a good timing and way based on the nutritional support planning.Preoperative fasting all night for the majority of patients is not necessary,patients should be allowed to intake low-concentration liquid diet at hour 2 before anesthesia.Patients with preoperative severe malnutrition should be given 7-10 days of nutritional support therapy.The enteral nutritional therapy was preferred to patients needing postoperative nutritional support therapy,while parenteral nutrition therapy should be supplied to patients with infeasible enteral nutrition or expected target of 60％ for enteral nutrition.Individual nutritional support therapy is not necessary for patients without severe concomitant disease.Pharmacological nutrients such as ω-3 polyunsaturated fatty acids and glutamine are beneficial for abdominal surgery and critical patients,which should be used reasonably.

Objective To observe the clinical efficacy of scraping therapy plus Yi Yi Ren (Semen Coicis) congee in treating functional dyspepsia due to dampness-heat blocking the stomach. Method Sixty-four patients were divided into an observation group and a control group by using the random number table, 32 cases in each group. The observation group was intervened by scraping therapy plus Yi Yi Ren (Semen Coicis) congee, while the control group was by Mosapride citrate dispersible tablets. The two groups were both treated for 4 weeks. The traditional Chinese medicine (TCM) symptom score, Nepean Dyspepsia Symptom Index (NDSI), and Nepean Dyspepsia Life Quality Index (NDLQI) were observed before and after the intervention and the clinical efficacy was evaluated, for comparison and analysis. Result The total effective rate was respectively 93.8%in the observation group and 78.1%in the control group, and the observation group was superior to the control group (P<0.05);after the intervention, the TCM symptom scores and NDSI scores dropped significantly in the two groups (P<0.05,P<0.01), and the NDLQI scores increased significantly in the two groups (P<0.05), and the improvements in the observation group were more significant (P<0.05). Conclusion Scraping therapy plus Yi Yi Ren (Semen Coicis) congee and Mosapride citrate dispersible tablets are both effective in treating functional dyspepsia due to dampness-heat blocking the stomach, while the former one can produce a more significant therapeutic efficacy and improve the symptoms and quality of life in a better way.

In order to clarify the relationship between PAMs and post—trauma lung injury, the H_2O_2 produced by PAMs and catalase activity of bronchoalveolar lavage fluid (BALF) and lung homogenate were measured at hours 6、12、24、48 and 72 after burn、blast injury and burn—blast combined injury in 128 rats, respectively. After trauma, H_2O_2 produced by PAMs was increased compared with PAMs from control lungs, especially in the combined injury groups. The catalase activity of BALF and lung homogenate decreased. The catalase activity in combined injured lungs was the lowest. The results indicated 1. the activation of PAMs might play a role in post—trauma lung injury: 2. the damage of pulmonary antioxidant system after trauma may enhanced the lung injury; 3. the state of PAMs activation and the damage of pulmonary antioxidant system were related to the severity of trauma.

Objective To compare the efficacy of pneumatic retinopexy and subretinal drainage in the treatment of primary rhegmatogenous retinal detachment(RD) in scleral buckling procedure.Methods Pneumatic retinopexy or subretinal drainage was applied during the scleral buckling procedure when lots of subretinal fluid existed.Results Twenty-three of 26 eyes(88.5%) were successfully reattached by pneumatic retinopexy during scleral buckling procedure for the repair of primary retinal detachment.New hole formation was the major complication for the surgical failure.One eye was fixed by another buckling procedure and the other two were treated by vitrectomy.Eleven of 12 eyes(91.7%) with primary RD were successfully managed by scleral buckling procedure and subretinal fluid drainage.Subretinal hemorrhage occurred in one eye after subretinal drainage.Conclusion Pneumatic retinopexy can substitute subretinal drainage in the repair of primary rhegmatogenous retinal detachment when plenty of subretinal fluid exists.

Objective To compare the anatomic and functional results of ocular intensive and systemic corticosteroid administration prior to vitrectomy for primary rhegmatogenous retinal detachment with choroidal detachment.Methods A retrospective,clinical pilot study.Results Of 38 cases of primary rhegmatogenous retinal detachment with choroidal detachment,11 cases received intensive 1% prednisolone acetate eyedrops once each hour,totally 16 times a day(Group A)for(4.91?1.51)days and 27 cases received systemic corticosteroid treatment which is performed as intravenous injection of 15 mg Dexamethasone for 3 d and then taped down for(5.67?1.88)days prior to vitrectomy(Group B).The rate of anatomic reattachment by one operation was 54.5% for Group A and 63.0% for Group B;The rate of reattachment by reoperation was 80% for Group A and 100% for Group B.The functional result was the same in the two groups,with the vision improvement in 70% cases of Group A and 68% cases of Group B.The minimal follow-up period was 3 months after final operation.Conclusion There is an obvious tendence of lower rate of anatomic reattachment in intensive steroid eyedrops treatment group than in systemic corticosteroid treatment group.However,the functional result is almost the same in the two groups.

OBJECTIVE：To study the secretion of catecholamine primary cultures of chromaffin cells from rat adrenal medulla were used.METHOD:Catechoalmines(norepinephrine,epinephrine and dopamine) were measured by high-performance liquid chromatography-electrochemical detection technique.RESULTS:Catecholamine released by chromaffin cells with in 20min without slimalus was (73.29±15.32) ng/106 cells.When acetylcholine,nicotine or muscarine was added,the secretion of catecholamine was then increased.CONCLUSION:Using high-performance liquid chromatography-electrochemical detection technique,we can detect sensitively catecholamine released by cultured rat chromaffin cells.

Objective To observe the incidence of ciliary detachment and its relationship with intraocular hypotension soon after vitrectomy.Methods A total of 46 eyes of 46 patients who underwent vitrectomy were examined by ultrasound biomicroscope (UBM).The patients were divided into three groups according to different tamponade: gas group (11 eyes),silicone oil group (8 eyes) and balanced saline solution (BSS) group (27 eyes).Basing on the postoperative intraocular pressure (IOP),the patients were divided into two groups: IOP<10 mm Hg (25 eyes) and IOP≥10 mm Hg (21 eyes).UBM was applied to determine the tomographic features of the ciliary body 3 days after the surgery.IOP were monitored by non-contact tonometer daily after the surgery.The eyes with ciliary detachment were then examined once a week till the ciliary detachment reattached.The follow-up period was from 14 to 35 days.Results After vitrectomy,ciliary detachment was observed in 20 eyes of 46 eyes (43.5%),The incidence of ciliary detachment was 27.3% in gas group,25.0% in silicone oil group,and 55.6% in BSS group.The average IOP in eyes with ciliary detachment [(6.47±4.49) mm Hg (1 mm Hg=0.133 kPa)] was significantly lower than that in the eyes without ciliary detaehmen [(15.61±7.72) mm Hg] (t=8.031,P<0.001).The incidence of ciliary detachment was higher in eyes with postoperative IOP <10 mm Hg (68.0%) than that in the eyes with postoperative IOP≥10 mm Hg (14.3%) (χ2=15.60,P<0.001).All eyes with postoperative ciliary detachment got spontaneous reattaehment within 30 days after the surgery except that one eye had optic disc edema due to severe intraocular hypotension.Conelusions Early postoperative ciliary detachment is a common complication after vitrectomy.Eyes filled with BSS have the highest incidence of postoperative ciliary detachment.Most of the patients with ciliary detachment may get spontaneous reattahment within 30 days after the surgery.
