Objective To determine the clinical value of EUS in combination with detection of CA19-9 and CA242 for early diagnosis of pancreatic cancer.Methods General features of high-risk group were determed by EUS and the plasma levels of CA19-9 and CA242 measured by ELISA.Results The serum level of CA19-9 was abnormal in 9.80% (10/102) and that of CA242 in 12.75% (13/102) of the patients.They were both abnormal in 7 cases.Of the 7 cases, 3 were found to suffer from pancreatic cancer by EUS, 1 had the tumor that had been clinically confirmed, 1 had posterior peritoneal tumor and 2 were normal.Among 102 cases detected by EUS, 2 showed low echo in pan-creatic head, 2 semi-cyst, 3 pancreatic cancer and proved by pathology.Accurate diagnotic rate, sensi-tivity and specificity were 90.20% (92/102), 50% (4/8) and 93.62% (88/94), respectively, for serum CA19-9.For the serum CA242, the 3 parameters were 87.25% (89/102), 50% (4/8) and 90.43% (85/94), respectively.For combination of both methods, they were 98.04% (100/102), 100%(8/8) and 97.87%(92/94), respectively.Accurate diagnostic rate of the latter was significantly higher than that of the former 2(P＜0.05).Concision Combination of EUS with detection of serum CA19-9 and CA242 is of great vlaue for early screening of pancreatic cancer.

Objective To explore the advantage of Body-Jet hydrodynamic liposuction system in autologous fat transplantation.Methods Through the unique hydrodynamic jet washing liposuction technology and the closed fat storage system,the fat was filtrated and purified,and then the fat was injected into the posterior space of greater pectoral muscle and breast tissue as well as subcutanous tissue of the breast with unique reverse-directed double orifice injector.During May 2015 to July 2016,27 patients were treated in our hospital and followed up for 30 to 180 days.Results All patients had good incision healing;there were no rugged skin,hematoma,seroma and other complications in the liposuction site.In 25 patients after augmentation the breast had rounded appearance and good feeling;1 patient presented liquefied fat,1 patient had poor survival of the injected fat;later 2 cases underwent second surgery.Conclusions The liposuction system can be applied in autologous adipose transplantation breast augmentation.The procedure is simple and quick.The survival rate after adipose transplantation is high with quick recovery.The shape of the breast is full and round with good feeling.

In order to improve the metabolism yield of cordycepin and adenosine,we studied nitrogen sources ,the levels of nitrogen sources and carbon sources,dynamic development in liquid culture ,as well as the total yield of cordycepin and adenosine in culture system through determining the contents of cordycepin and adenosine by HPLC .The results are as follows: not only animal protein but also some plant protein is very good nitrogen sources; in culture solution the suitable levels of nitrogen sources and carbon sources is respectively 3% and 4%; the content of adenosine in culture solution is very low, while it is quite high in mycelia; it is much higher that the total yield of cordycepin in culture solution than in mycelia; when the culture system is oscillated and cultured after 7~9 days, the total yield of cordycepin and adenosine are both high.

In this paper, we expatiate the advance of Tricholoma matsutake including distributing, environment, pure culture, domesticating cultivation and artificial forcing breeding in the area of Changbai Mountain of China.

Objective To discuss the effect of “practice teaching methods ” in musculoskeletal ultrasound diagnosis training process .Methods Thirty refresher doctors for a month with the method training .The effect training is evaluated by objective exam and questionnaire survey .Results Thirty refresher doctors received tests before and after the training .Test results showed that the accuracy after the training was significantly higher than that of before ( P<0.05 ) .Refresher doctors survey about satisfaction of the training method showed that whole satisfaction is 100%, in which 70%were very satisfied , 30%were satisfied .The self-assessment results for the improvement of the level of diagnosis musculoskeletal ultrasound showed that 45%doctors are very satisfied ,40%doctors are satis-fied, and 15%is not satisfied .Conclusions With the implementation of “teaching by practice” method, refresher doctors could master the knowledge of musculoskeletal anatomy as soon as possible , and have the ability to diagnose common musculoskeletal diseases independently .

AIM:To evaluate the feasibility and advantages of two-port 27-gauge pars plana vitrectomy for treatment of recurrent retinal detachment in silicone oil dwelling eyes.METHODS:A retrospective study.Two-port 27-gauge pars plana vitrectomy was performed in 7 eyes with recurrent retinal detachment without remove of silicone oil.Proliferative membrane peeling, endolaser treatment, and drainage of subretinal fluid were performed.Scleral bulking was performed if necessary.RESULTS:Sucessful retina re-attachment was accomplishied in all eyes.No visually significant intraoperative complication occurred.All eyes expericend quick recoveray of visual acuity and mild postoperative irritation.One eye developed a recurrent inferior retinal detchment in 20d after the surgery using non-remove technique, and recovered after conventional silicone oil removal and retinal reattachment surgery.CONCLUSION:Two-port 27-gauge pars plana vitrectomy is an efficacious (and potentially cost-efficient) method to treat early stage recurrent retinal detachment in silicone oil dwelling eyes.

Objective To assess the application of echocardiography in mini-invasive surgical device closure of ventricular septal defect (VSD). Methods 73 VSD patients including 35 with aneurysm formation and among them 21 with multi-defects in the aneurysm were treated by mini-invasive device closure. A closure device was positioned to the defect through parastemal mini-incision in all patients. TEE was used to monitor the whole procedure, to guide the device positioning and to evaluate the curative effect instantly after operation. All patients were evaluated by TTE one year postoperatively. Results All patients were successfully positioned closure devices by TEE guiding. 9 cases were found with trace to small amount residual shunt instantly after operation. 7 cases still had small amount residual shunt at the time of 48 hours after the operation. In the one year follow-up, 4 cases had residual shunt, but the size and volume of left ventricle were significantly reduced than those before operation, and the pulmonary artery systolic pressure was also reduced. Conclusion Echocardiography possesses an important role in preoperative indication screening, intraoperation monitoring and evaluating the curative effect postoperatively.

Prostate cancer (PCa) is one of the most common malignancies in the urinary system of males. A growing number of studies have shown that microRNAs, as small ribonucleic acid molecules and a class of non-coding small RNAs, are closely related with PCa and a variety of microRNAs are abnormally expressed in it. This article focuses on the roles of microRNAs in the occurrence and progression of PCa, with a description of differentially expressed microRNAs in PCa and an analysis of their association with its prognosis as well as their correlation with chemotherapy, androgen receptors, and metastasis of PCa.

Orthogonal combination design was adopted in examining the Spirulina platensis (S. platensis) yield and the influence of four factors (Se content, Se-adding method, S content and NaHCO3 content) on algae growth. The results showed that Se content, Se-adding method and NaHCO3 content were key factors in cultivation conditions of Se-enriched S. platensis with the optimal combination being Se at 300 mg/L, Se-adding amount equally divided into three times and NaHCO3 at 16.8 g/L. Algae yield had a remarkable correlation with OD560 and floating rate by linear regression analysis. There was a corresponding relationship between effects of the four factors on algae yield and on OD560, floating rate too. In conclusion, OD560 and floating rate could be served as yield-forming factors.
