Objective To evaluate efficacy and safety of escitalopram in treating depression. Methods In this randomized, double-blind, double-mimicry, paroxetine parallel controlled study,the study group was treated with escitalopram and the control group with paroxetine. Hamilton Rating Scale for Depression was taken to evaluate efficacy score. Results At the end of six weeks,compared with the total scores of HAMD before and after treatment, escitalopram (17.5±7.8) and paroxetine (16.0±7.9) group both showed the significant difference, while the difference compared between two groups ,the efficacy (87.0% and 81.7%) for depression and side effects were no significance. Conclusion Escitalopram is an efficient and safety antidepressant.

Objective To compare and analyze clinical and pathological data of autopsyconfirmed invasive fungal disease (IFD) in elderly patients in order to achieve a better understanding of the clinical and pathological characteristics of IFD.Methods A total of 18 cases of IFD were diagnosed by autopsy from 1984 to 2014 at Beijing Hospital.Clinical and pathological data of IFD,including risk factors,clinical manifestation,X-ray and pathological characteristics,were analyzed retrospectively.Results The 18 cases were all male wvith an average age of (83.7±7.2) years and each patient had at least one risk factor for IFD.Of them,14 patients (77.8％) suffered malignancies of various origins.With respect to the pathogens,Mucor (6 cases) was the most common one,followed by Aspergilla (4 cases),Mycotoruloides (4 cases) and Cryptococci (2 cases).The lung was the most frequently implicated organ wvith 13 cases (72.2％),followed by the gastrointestinal tract.Vascular erosion was an important pathological characteristic of fungal infection,whose presentations included vasculitis,hemorrhage and embolism in tissues and organs.14 patients died from fungal infection-related causes,of which.massive hemorrhage as a result of vascular erosion by fungal infection was responsible for four patients' deaths.Conclusions Malignancies are an important risk factor for invasive fungal disease in elderly patients.Vascular erosion is a significant character of fungal infection.

Abstract?Since the introduction of 25-gauge/23-gauge ( 25G/23G ) sutureless micro -incision vitrectomy surgery ( MIVS ) at the beginning of the 21 century, we have stepped into an era of micro-incision vitreoretinal surgery more than10a. The current 25/23G MIVS provide numerous advantages over the conventional 20G vitrectomy surgery including simplified surgical procedure, shortened operating time, decreased complications as well as smaller sclerotomy wound.As a result, vitreoretinal surgeons have been shifting gradually from 20-gauge to 25/23-gauge vitrectomy in the past decade. As the 25/23G MIVS adapted worldwide, however, its drawbacks were also increasingly reported. Most criticism regarding to current 25/23G MIVS are focusing on would sealing related complications.Based on stablished notion regarding vitrectomy -“the smaller the better”, researchers and doctors were keeping on exploring the next generation of vitrectomy system. Thanks to the innovation and development in new generation vitrectomy machines, high lumen output light source, more delicate manufacturing technology and clear wild angle fundus view system, Dr.Oshima from Japan launched the first 27-gauge vitrectomy surgery system.It provided us novel surgical experience with smaller sclerotomy wound and faster cut rate. Further development and refinement of vitrectomy with 27-gauge or more are still on its way and will continue in the future. Undoubtedly, MIVS would be heated debated regarding its pro/con, complications, indications and future development.Combined with our own experiences, here we briefly reviewed the 27-gauge vitrectomy surgery.

ObjectiveTo evaluate the effect of low glycemic index(LGI)diet and exercise on plasma glucose and lipid profiles in newly diagnosed type 2 diabetic patients. MethodsSeventeen newly diagnosed type 2 diabetic patients with FPG ≤ 10mml/L treated by LGI diet and exercise only for two months.Fasting plasma glucose (FPG),2 hours postprandial glucose(2hPG),glycosylated hemoglobin A1 C(GHbA1C),and lipid profiles were measured.The results of FPG,2hPG,GHbA1C,and lipid profiles were compared. ResultsTwo months after treatment,the level of fasting glucose(6.19 ± 0.60)mmol/L,postprandial 2h plasma glucose(8.59 ± 0.90)mmol/L,TG(1.15 ± 0.45)mmol/L,TC(4.98 ± 0.77)mmol/L,LDL(3.20 ± 0.71)mmol/L were significantly lower than (7.84 ± 1.19)mmol/L,(13.97 ± 3.35)mmol/L,TG(1.79 ± 0.75)mmol/L,TC(5.46 ± 0.27)mmol/L,LDL (3.57 ± 0.28)mmol/L,HDL(1.59 ± 0.30)mmol/L was significantly higher than(1.42 ± 0.26)mmol/L,the differences were statistically significant(all P＜0.05);HbA1c(6.49 ± 0.57)% was slightly lower than(7.29 ±0.77)%,but the difference was not significant(P＞0.05);No hypoglycemia was observed during the treatment. ConclusionThe exellent glycemic control and improvement of lipid profile could be achieved by low glycemic index diet and exercise only.Furthermore,no hypoglycemia occurred during the treatment.

[ABSTRACT]OBJECTIVETo explore the efficacy and safety of localization for parathyroid glands with intravenous low dosage of methylene blue in thyroidectomy. METHODSWe retrospectively reviewed the clinical data of 41 patients who suffered from thyroid papillary carcinoma between Aug, 2014 and Jan, 2015 (9 males and 32 females, with a median age of 46 years). Thirty eight patients underwent primary thyroidectomy and 3 patients underwent second operation. A variety of thyroidectomy was performed in all patients, and who also underwent intravenous (3-4) mg/kg methylene blue in operation. RESULTSEighty four parathyroid glands were stained. Among 39 patients who's parathyroid glands were stained, the mean dyeing time was (31.27±9.41) min. Dyeing rates and dyeing time were not significantly different between 3 mg/kg group and 4 mg/kg group (t=0.24 and 0.20, all P>0.05). None of patients had the hypoparathyroidism problem such as peri-oral numbness, tingling, muscle aches and spasms. According to postoperative monitoring of parathyroid hormone, all of patients had no permanent hypofunction of the parathyroid gland. Neurotoxic effects and other serious side effects were not observed in all patients. CONCLUSIONIntravenous low-dose methylene blue in thyroidectomy is a safe, easy, and effective technique that facilitates rapid identification of parathyroid gland.

Objective To study helper T lymphocyte cell(Th)1/Th2 imbalance in rats′ model of asthma and the modulation of lentinan(LNT) on the airway inflammation and Th1/Th2 imbalance.Methods Thirty male SD rats were randomly divided into control,asthma and LNT groups.In the experiment,the rat model of asthma was established by the ovalbumin(OVA) challenge methods.Eosinophils(Eos) number and differentiated cell number in bronchoalveolar lavage fluid(BALF) were counted by different count fluids.The levels of IL-4 and IFN-? in BALF were measured by sandwich enzyme linked immunosorbent assay(ELISA).Results 1.The Eos count in BALF and the ratio of eosinophils to the total cell number(Eos%) of asthma group were significantly higher than those of the control group(t=21.94,12.81 Pa
