2.Hot topics in the perioperative nutritional support therapy in abdominal surgery
Chinese Journal of Digestive Surgery 2015;14(5):361-364
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.
3.Therapeutic Observation of Scraping Therapy plus Yi Yi Ren (Semen Coicis) Congee for Functional Dyspepsia Due to ;Dampness-heat Blocking the Stomach
Shanghai Journal of Acupuncture and Moxibustion 2016;35(10):1203-1205
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.
4.Role of Pulmonary Alveolar Macrophage in Lung Injury after Burn—Blast Combined Injury
Chinese Journal of Trauma 1990;0(04):-
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 statistically analyze the bacterial flora change and drug resistance situation in the patients with bacteri‐al infection to provide reference for clinical rational drug use and the management of nosocomial infection .Methods The clinical samples were conventionally isolated and cultured .The bacteria identification and drug sensitivity test were performed by using the bioMerieux company VITEK2 automatic microorganism analyzer .The confirmation test of drug susceptibility adopted the disk dif‐fusion method recommended by the American Clinical and Laboratory Standardization Committee (CLSI) .Results The sample sources in the hospital infection during 2011-2013 were main sputum ,secretions and midstream urine ;the main infectious bacteria showed the increasing trend ,the top 5 of bacteria were :Escherichia coli (ECO) ,Klebsiella pneumoniae (KPN) ,Acinetobacter bau‐manii (ABA) ,Pseudomonas aeruginosa (PAE) ,Staphylococcus aureus (SAU);the top three of common multi‐drug resistant bacte‐ria were ABA ,PAE and ECO ,their constituent ratio during these three years had a small amplitude increase ;the antibiotics for Gram negative bacilli (G -) resistance rate of more than 70% during these 3 years were :ampicillin ,cefuroxime sodium and cefu‐roxime axetil;the antibiotics for Gram positive cocci (G+ ) resistance rate of more than 70% during these 3 years were penicillin and erythromycin ..Except for 4 cases of Enterococcus faecalis ,no other vancomycin‐resistant strains were found .Conclusion The sam‐ple source of bacterial infection is dominated by sputum ,the gram negative bacteria are the main force of hospital infection ,showing a increasing trend every year ,multi- drug resistant strains are also continuously rising ,penicillin is unsuitable to the clinical treat‐ment of bacterial infection ;imipenem has very high sensitivity to ECO and KPN .The hospital should attach great importance to the infection management ,strengthen the application and management of antibiotics ,decrease the outbreak and prevalence of bacterial infection and reduce the increase of drug resistant strains .
8.Clinical obsrevation on early postoperative intraocular hypotension and ciliary deatchment after vitrectomy
Chinese Journal of Ocular Fundus Diseases 2009;25(1):22-25
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.
9.Biological and biomechanical properties of reconstructing anterior cruciate ligament of knee joint
Chinese Journal of Tissue Engineering Research 2005;9(26):265-267
OBJECTIVE: To probe into the function of early exercises on healing of grafts after anterior cruciate ligament (ACL) reconstruction and on motor function recovery of knee joint by summarizing biology and biomechanical properties of ACL reconstruction.DATA SOURCES: The relevant literatures on ACL reconstruction of knee joint and its biomechanical properties were looked up in period of MEDLINE1970-01/2004-01 on computer. Retrieval words: "anterior cruciate ligament, knee joint, biomechanics" only in English.STUDY SELECTION: In initial examination, the complete contents of literatures on ACL reconstruction of knee joint and its biomechanical properties were selected. The controlled papers were randomized, for those written by the same writer, the papers with the most cases were included.Comprehensive and Mete analyzed papers were excluded. Quality evaluation was mainly based on the reality of observed data and rigor of investigation and application.DATA EXTRACTION: Fourty-six papers on ACL reconstruction of knee joint and its biomechanical properties were looked up totally, of which, 29papers were tallied with inclusive criteria, 17 papers were excluded, 9 papers were the analysis on small samples and 8 papers referred to comprehensive and Meta analysis.DATA SYNTHESIS: By understanding biomechanical properties of normal ACL it is to implement reconstruction measures and plan for rehabilitation. Animal experiment after ACL reconstruction suggests that the motor function recovery of knee joint is not satisfactory, but the results of human experiment are superior to animal one. It is indicated in randomized control experiment that immediate weightbearing right after ACL reconstruction will not aggravate knee joint laxity; on the contrary, it is advantageous to alleviate patellar pain.CONCLUSION: Reconstruction of injured ACL fixes knee joints, limits peripheral muscle contraction and results in limited motor function of ligaments, joints and peripheral muscles. Early rehabilitation exercises may alleviate pain, improve articular cartilage metabolism, prevent capsule contracture and benefit recovery of motor function after ACL reconstruction of knee joint.In randomized comparisons of Bear[27], Fischer[28] and Beynnon[29],there is no difference between rehabilitation at home and in hospital after ACL reconstruction with bone-patellar-bone graft.
