Objective To explore the method of flow cytometric analysis for T-lymphocyte subpopulations in bronchoalveolar lavage fluid(BALF) and evaluate its clinical significance in diagnosis of lung cancer.Methods Forty-seven BALF were collected from the patients with lung cancer or benign pulmonary disorders.T-lymphocyte subpopulations were detected by 3-colour staining method of CD4FITC/CD8PE/CD3PerCP in flowcytometer.Results The percentage of Th and Ts cells were(35.76?7.71) % and(64.31?7.37) % respectively,and Th/Ts was(0.57 ? 0.18) in the BALF of lung cancer,while they were(49.27 ?12.88) %,(44.54 ?9.56) %,and(1.13 ?0.29) in the BALF with benign pulmonary disorders.The percentage of Th cells in the BALF of lung cancer were lower than that in the BALF of benign pulmonary disorders(P

Optical coherence tomography angiography (OCTA) is a new emerging technology that is widely used in diagnosis of ocular diseases recently.It has the capability to generate high resolution 3D angiograms of retina and choroid,dissect and visualize the flow in various layers of the retina,and provide more informations of the structure and function of the retina simultaneously.Nevertheless,OCTA is in the early stage of clinical evaluation,so studies on imaging various diseases by OCTA are still on the way.In this article,we reviewed literatures of clinical research on OCTA,and summarized its current research situation,values of optic diseases and drawbacks,which guide its clinical application.

This study was undertaken to investigate the response of nonimmunologic contact urticaria(NICU) test before and after ingestion of cimetidine, homoclorcyclizine and indomethacin. Thirty-five patients who showed positive reaction to 5% benzoic acid (BA) in petrolatum (pet) by 20 minutes closed patch test were chosen and divided into 4 groups. Group I was consisted of 10 patients who were taken cimetidine 200 mg single dose, group 2, 9 patients, taken hornoclorcyclizine 10mg single dose or 30mg divided dose, group 3. 8 patients, taken indomethacin 100 mg single dose and group 4. 8 patients, taken indomethacin 50 mg tid. All the patients were tested with 5%. 2.5%. l%, 0.5%, and 0. l% BA in pet using Leukotape on the riight arm before rnedication and next day on the left arm after medication of each drug. Cimetidine and homoclorcyclizine did not show any significant differences before and after ingestion of drugs. Indomethacin, the cyclo-oxygenase inhibitor, blocked the reaction completely in half of the patients and reduced the reaction in almost all patients, regardless of doses. This results suggested that NICU induced by BA is not mediated by histamine but probably by prostaglandins.

Kidney is the most important organ to maintain the balance of hyperkalemia.Due to reduced glomerular filtration rate or renal tubule potassium excretion dysfunction, all kinds of acute and chronic kidney diseases can result in increased hyperkalemia.Therefore, hyperkalemia becomes a common electrolyte disorder in children with kidney disease.Hence, the diagnosis and differential diagnosis of renal hyperkalemia are particularly important for clinicians.

Objective To evaluate the stimulative role of the enhanced recovery program after surgery (ERAS) protocol in patients undergoing radical resection for gastric cancer.Methods A total of 102 consecutive patients undergoing elective gastric resection were included in either the ERAS (n =35,received ERAS perioperative treatment from June 2013 to June 2014) or the control group (n =67,received conventional perioperative treatment from June 2011 to June 2013).Outcomes related to nutrition index,stress index,and recovery index were measured.Results The nutritional index of patients (total lymphocyte count,serum albumin and prealbumin) in the ERAS group was improved on postoperative day (POD) 1 compared with that in the control group [(1.25±0.65) × 109/L vs (1.09±0.71) × 109/L,(36.4±5.2) g/L vs (31.3±4.1) g/L,(0.19±0.08) g/L vs (0.17±0.05) g/L,P ＜ 0.05,respectively].The level of negative nitrogen balance on POD 1 in the ERAS group was slightly lower than that in the control group (P ＞ 0.05),and the level of negative nitrogen balance on POD 7 in the ERAS group was higher than that in the control group (-0.93±2.17 vs -3.87±4.45,P ＜ 0.05).The postoperative cortisol level in the control group was elevated on both POD 1 (P ＜ 0.05) and POD 7 (P ＜ 0.05) compared to the preoperative level [(5.06±1.87) mg/L vs (3.60±1.5) mg/L],(5.15±1.33) mg/L vs (3.60±1.51) mg/L,P ＜ 0.05,respectively].However,the cortisol level was not increased until POD 7 in the ERAS group [(5.08±1.18) mg/L vs (3.20±1.43) mg/L,P ＜ 0.05].The level of IL-6 was elevated in postoperative period compared to preoperative period both in two groups (P ＜ 0.05).And the level of IFN-γin the ERAS group on POD 1 was reduced compared to the preoperative level (P ＜ 0.05).Whether in preoperative or postoperative,the level of IL-1β and TNF-α showed no statistical significance change.In addition,the postoperative recovery conditions (day of oral all-liquid recovery,first day of defecation,hospital stay,maximum pain on visual analogue scale) in the ERAS group were better than those in the control group (P ＜ 0.05).The incidence rates of complications between the two groups were 13.4 ％ (9/67) and 17.1％ (6/35) respectively (P ＞ 0.05).Conclusion ERAS protocol can alleviate surgical stress response and accelerate postoperative recovery without compromising patients' safety.

Objective To improve lower eyelid blepharoplasty by using myocutaneous flap and lateral one-third skin flap.Methods A total of 37 patients were recruited in this study and received lower eyelid blepharoplasty.Incision was made at the lower palpebral margin,and the extension of incision was hided into the outer canthus rhytids.Myocutaneous flap was made first followed by the preparation of skin flap at the lateral one-third of the lower eyelid.Results All the patients experienced a quick recovery from the surgery.The excess skin at the lateral canthus was completely removed,the incision was sutured under moderate tension,and the eyelid skin was flattened.No lid-retraction or lower eyelid ectropion was observed in the 6-to 12-month postoperative follow-up.The lateral incision sear was hidden and the operation outcome was satisfactory.Conclusions The lower eyelid blepharoplasty with myocutaneous flap and lateral one-third skin flap may lead to a satisfactory outcome with the formation of natural outer canthus angle and make the patients younger.
