Objective To explore the characteristics of uhrasonography of hepatobiliary cystadenoma. Methods The ultrasonographic characteristics of 5 cases with hepatobiliary cystadenoma were retrospectively analysed, and compared with the operation and pathology. Results The ultrasonography of 5 cases was multilocular cystic mass,which seems to be,but not indeed communicating with the biliary tree,in which irregular septation was demonstrated in two-dimensional structure and also with perforator vessels along in color Doppler flow imagineg. And in some cases small papillary tuft and small loci of calcification was noted on the septation. Conclusions Muhilocular cystic mass,locating along the biliary tree, however not communicating with the the biliary tree, is an important diagnostic basis of biliary cystadenoma. And it should be distinguished with other cystic tumor in the liver.

Objective To investigate the relationship between p62 expression,and occurrence and metastasis of nasopharyngeal carcinomas.Methods Immunohistochemical method was used to analyze p62 expression in 123 nasopharyngeal carcinoma (NPC) cases and 30 chronic nasopharyngitis cases.The clinical pathological characteristics were analyzed.Results The positive rate of p62 protein in chronic nasopharyngitis nasopharyngeal epithelium,non-metastatic NPC tissue,and metastatic NPC tissues was 13.3％,66.67％,and 84.72％,respectively,and the difference was statistically significant.The expression of p62 protein in nasopharyngeal carcinoma patients with lymph node metastasis or distant metastasis was significantly higher than non-metastatic NPC patients (P ＜ 0.01 or P ＜ 0.05).However,the expression of p62 was not related to age,gender,tumor size,and TNM stage (P ＞ 0.05).Conclusions High p62 protein expression in nasopharyngeal carcinoma tissue is closely related to the occurrence and metastasis of nasopharyngeal carcinomas.It provides good reference value to predict NPC malignancy and metastases.

Objective To observe the effects of hyperbaric oxygen on atony after hemiplegia. Methods40 cases with hemiplegia were divided into 2 groups: treatment group (n=17) accepted hyperbaric oxygen and rehabilitation, while control group (n=23) accepted rehabilitation only. The muscle strength, muscle tone and elderly mobility scale (EMS) were measured before and after treatment. ResultsAfter 20 times of treatment, the muscle strength, muscle tone and scores of EMS improved in both groups (P<0.01), and was more significantly in treatment group than in control group (P<0.05). ConclusionHyperbaric oxygen can facilitate the recovery of muscle strength and muscle tone in hemiplegia patients, and improve their motor function.

Characteristics and measurement principles of reference methods in clinical biochemistry were described.Implementation of reference systems is one of the most effective approaches to improve the accuracy and comparability of clinical laboratory test results.Reference methods are the key components of reference systems.Reference methods should have measurement uncertainties that meet the requirements of the intended use,and thus should be based on reliable measurement principles.For the well-defined biochemistry analytes,reference methods have been almost all based on instrumental analysis.Isotope dilution mass spectrometry (ID/MS) is considered most reliable and has been the major analytical principle of the reference methods.ID/MS analysis is accurate but expensive.Use of other validated instrumental analyses as reference measurement principles would be justified.

To summarize the present situation of research on amylolytic lactic acid bacteria and its amylase,and the fermentation technology of amylolytic lactic acid bacteria.The amylolytic lactic acid bacteria have the ability of secreting amylase,can direct ferment starchy material into lactic acid without hydrolysising processes,simplify the production process,and saving the equipment investment,thereby,decrease the cost of production.Amylolytic lactic acid bacteria isolated from traditional fermented food,or from organic waste and kitchen waste.The mechanism of direct utilize starch raw materials by the amylolytic lactic acid bacteria were introduced,the fermentation technology of amylolytic lactic acid bacteria were compared.Meanwhile it was pointed out that through mutation breeding and genetic engineering methods gain the potent amylolytic lactic acid bacteria,and use the advanced fermentation and separation technology can improve the productivity of lactic acid.

Objective To investigate the safety and feasibility of modified hand-assisted laparoscopic surgery (MHALS) in the abdominal surgery.Methods The clinical data of 8 patients who underwent long-sleeved MHALS at the First People's Hospital of Foshan between September 2014 and January 2015 were retrospectively analyzed.Among the 8 patients,right liver cancer with intrahepatic metastasis was found in 2 patients,left liver cancer in 1 patient,hepatic peripheral nerve sheath tumor in 1 patient,left retroperitoneal leiomyosarcoma in 1 patient,extra-and intra-hepatic cholangiolithiasis in 1 patient,choledochocyst in 1 patient and ampulla cancer in 1 patient.Laparoscopic protection sleeve went through the middle of incision-retractor,and then wrapped around it about 10 cm.Incision-retractor was fixed at the abdominal incision firstly,laparoscopic procedures were performed when the wrist of assisted hand was bound and fixed by the distal of sleeve.The patients were followed up by outpatient examination and telephone interview till March 2015.Results All the 8 patients underwent successful MHALS,including 1 of right hemihepatectomy in situ,1 of ligation of right portal vein + left liver split (the patient gave up two-stage operation due to intractable ascites and elevated bilirubin),1 of hepatic left lateral lobectomy (the patient underwent hemostatic sutures in open surgery due to hemorrhage of liver's cutting surface),1 of hepatic peripheral nerve sheath tumor resection,1 of left retroperitoneal leiomyosarcoma resection,1 of choledocholithotomy + left hepatectomy + cholecystectomy + T tube drainage,1 of choledochocyst + biliary enteric drainage and 1 of pancreaticoduodenectomy.Four patients had assisted incision of 4 cm,and another 4 patients of 7 cm.Eight patients were followed up for a median time of 3 months (range,2-7 months).The patient who received ligation of right portal vein + left liver split died at postoperative month 3,and the others didn't have recurrence of tumor or lithiasis.Conclusion The MHALS is safe and feasible in the abdominal surgery.

?AIM: To evaluate the effects on recovering of corneal wound and postoperative discomfort of different methods for primary pterygium.?METHODS: Forty-seven cases ( 60 eyes ) of primary pterygium were excised under microscope with limbal epithelial transplantation, with sharp dissection ( 24 cases, 30 eyes, Group A) and blunt dissection (23 cases, 30 eyes, Group B).All cases were followed up for 1d to 1mo.?RESULTS: The recovering of corneal wound was better in Group B on 1st day and 3rd day after surgery.Pain, photophobia and tears, foreign body sensation were more serious in group A on 1st day after surgery with a statistically significant difference (P=0.005,0.015,0.012). Pain, photophobia and tears, foreign body sensation were more serious in Group A on 3rd day after surgery with a statistically significant difference ( P=0.019,0.018, 0.015).There was no statistically significant difference on 1wk and 1mo after surgery (P>0.05).? CONCLUSION: Compared with sharp dissection, primary pterygium excised with blunt dissection can significantly improve recovering of corneal wound and postoperative discomfort.

Objective To investigate the antitumor therapeutic effect of combined therapy of magnetic induction heating by nano-magnetic particles, herpes simplex virus thymidine kinase gene(HSV-tk suicide gene) and internal radiation in mice bearing MCF-7 breast carcinoma. Methods The transfection reagents, plasmids heat shock protein-HSV-tk (pHSP-HSV-tk), ferroso-ferric oxide nano-magnetic fluid flow and 188Re-ganciclovir-bovine serum albumin-nanopaticles (GCV-BSA-NP) were prepared. The heating experiments in vivo were carried out using ferroso-ferric oxide nano-magnetic fluid flow. Sixty mice tumor models bearing MCF-7 breast carcinoma were established and randomly divided into six groups. Group A was the control group, B was gene transfection therapy group, C was hyperthermia group, D was gene transfection therapy combined with radionuclide brachytherapy group, E was gene therapy combined with hyperthermia group, and F was gene therapy, hyperthermia combined with radionuclide brachytherapy group. The tumor growth, tumor mass and histopathological changes were evaluated. The expression of HSV-tk in the groups of B, D, E and F was detected by RT-PCR. Poisson distribution and one-way analysis of variance (ANOVA) were used for statistical analysis by SPSS 10.0 software. Results In the animal heating experiments, the temperature of tumor increased up to 39.6 ℃, 43.2 ℃, and 48.1 ℃ quickly with different injected doses (2, 4 and 6 mg respectively) of nano-magnetic particles and maintained for 40 min. The temperature of tumor tissue reduced to 36.8 ℃, 37.5 ℃ and 37.8 ℃ in 10 min when alternating magnetic field (AMF) stopped. The tumor mass in Groups C ((452.50 ±30.29) mg), D ((240.98 ±35.32)mg), E((231.87 ±27.41) mg) and F ((141.55 ±23.78) mg) were much lower than that in Group A ((719.12±22.65) mg) (F=800.07, P＜0. 01), with the most significant treatment effect in Group F.The tumor mass in Group B((684.05 ±24.02) mg) was higher than that in Group D (t =32. 805, P ＜0. 05). Semi-quantitative RT-PCR analysis showed that the expression of HSV-tk in Groups B and D (0.33 ±0. 13 and 0. 46 ±0.12) was significantly different from that in Groups E and F (0.66 ±0.13 and 0.74 ±0. 11)(F = 21. 573, P ＜ 0.05). Conclusion Combined use of hyperthermia, gene therapy and radionuclide brachytherapy could effectively depress the growth of MCF-7 breast carcinoma, thus possessing treatment potential for this tumor.
