Injectable lipid emulsions have been routinely used in patients since 1960s as a nutritional supplement for patients requiring parenteral nutrition. In recent years, lipid injectable emulsions have been extensively studied as a kind of novel drug carrier, also the quality problems of the lipid emulsion attract more and more attentions gradually. Large diameter tail of injectable lipid emulsions as a significant quality control indicator should pay more attention. Regarding to the defect of detecting large diameter tail of lipid injectable emulsions in our country, the purpose of this article is to summarize the techniques of detecting large diameter tail, illustrate the impacts of large lipid droplet on the quality of lipid injectable emulsions, emphasize the importance of detecting large diameter tail in lipid emulsions and provide guidance for researching and developing lipid emulsions in domestic market.

Objective To investigate the prevalence of serum Anti-sperm antibodies(AsAb) in group of prepubertal boys with cryptor-chidism before and after surgery,and explore whether it may be influenced by testicular location,orchiopexy,unilateral or bilateral cryptorchi-dism and deferens and(or) epididymis abnormality.Methods Serum AsAb was examined in 50 prepubertal boys with cryptorchidism and 50 boys with oblique inguinal hernia before and 6 months after surgery.Fifty boys who were normal were served as controls.IgG and IgM AsAb were determined by the immunodotting method.Results The preoperative and post-orchiopexy serum AsAb positive rates in cryptorchid boys were significantly higher than the preoperative and post-high ligation of hernial sac ones respectively in boys with oblique inguinal hernia(Pa0.05).Conclusion Cryptorchidism may induce an autoimmune response against sperm antigen in prepuberty independent of testicular location,orchiopexy,unilateral or bilateral cryptorchidism and deferens and(or) epididymis abnormality.

ObjectiveTo explore the diagnostic methods and surgery pattern at the first time of spontaneous perforation of congenital choledochal cyst.MethodsEleven cases(4 male,7 female) with spontaneous perforation of congenital choledochal cyst were 6 months to 5 years old,and their average course of disease were 4 days.Gustily abdominal distension,abdominal pain,crying and fever were present in all cases.Jaundice(7 cases) and emesis(5 cases) appeared.All cases were detected with physical sign of peritonitis by physical examination.Choledochal cysts were confirmed by CT or B ultrasound in 8 cases.All cases accepted abdominal paracentesis and biliary ascites was drawn.Three different operative procedures were performed:choledochocyst excision & Roux-Y choledocho-jejunostomy(2 cases),choledochotomy with T-tube drainage(3 cases),and cholecystostomy(6 cases).Nine children receiving external drainage operation accepted a second operation to rebuild biliary tract(choledochocyst excision & Roux-Y choledochoje-junostomy) after 3 to 6 months.ResultsAll cases had got satisfactory therapeutic efficacy without any grave complication such as fistula of anastomotic stoma,infection of biliary tract or obstruction of biliary tract.During operation,perforations were located in the juncture of choledochus and cystic duct in 5 children and were not found in the other 6 children.In the second operation,the cases receiving cholecystostomy had less peritoneal adhesion,anatomic structure changes,haemorrhage[(30-50) mL vs(100-200) mL] and operation time[(2.5-3.0) h vs(3.5-5.0) h] than those receiving choledochotomy with T-tube drainage,and did not appear inadequate drainage for cystic duct obstruction.ConclusionsFor children with more organ inflammatory edema and adherence and in a bad overall condition,the first-time operation of cholecystostomy is more reasonable.

To study the in situ intestinal absorption of five oligosaccharides contained in Morinda officinalis How. (sucrose, kestose, nystose, 1F-Fructofuranosyinystose and Bajijiasu). The absorption of the five oligosaccharides in small intestine (duodenum, jejunum and ileum) and colon of rats and their contents were investigated by using in situ single-pass perfusion model and HPLC-ELSD. The effects of drug concentration, pH in perfusate and P-glycoprotein inhibitor on the intestinal absorption were investigated to define the intestinal absorption mechanism of the five oligosaccharides in rats. According to the results, all of the five oligosaccharides were absorbed in the whole intestine, and their absorption rates were affected by the pH of the perfusion solution, drug concentration and intestinal segments. Verapamil Hydrochloride could significantly increase the absorptive amount of sucrose and Bajijiasu, suggesting sucrose and Bajijiasu are P-gp's substrate. The five oligosaccharides are absorbed mainly through passive diffusion in the intestinal segments, without saturated absorption. They are absorbed well in all intestines and mainly in duodenum and jejunum.

OBJECTIVETo observe the effect of Shenshuaining Granule (SG) combined telmisartan on serum creatinine (SCr) levels and urinary albumin contents in diabetic nephropathy (DN) patients, and to explore its efficacy.

METHODSTotally 204 DN patients were recruited, and further assigned to 3 groups, i.e., the early DN group, the clinical stage of DN with normal renal function group, the clinical stage of DN with insufficient renal function group. Patients in the same group were randomly allocated to the telmisartan treatment group, the SG treatment group, and the combination of SG and telmisartan treatment group, 68 in each group. Patients in the telmisartan treatment group took telmisartan tablet, 80 mg per day, once daily. Those in the SG treatment group took SG, 5 g each time, 3 times per day. Those in the combination of SG and telmisartan treatment group took telmisartan tablet (80 mg per day, once daily) and SG (5 g each time, 3 times per day). The therapeutic course for all was 3 successive months. SCr levels, serum urea nitrogen (BUN),24 h urine microalbumin (24 h U-MA) were detected before and after treatment. Results In three different treatment groups, 24 h U-MA decreased after treatment in the telmisartan treatment group; SCr and BUN decreased after treatment in the SG treatment group; and 24 h U-MA, SCr and BUN decreased after treatment in the combination of SG and telmisartan treatment group (P<0.05). In the clinical stage of DN with insufficient renal function group, SCr obviously increased after treatment in the telmisartan treatment group (P <0. 05). In the 3 DN stages, SCr and 24 h U-MA obviously decreased in the combination of SG and telmisartan treatment group, when compared with the telmisartan treatment group and the SG treatment group (P<0.05). Compared with the telmisartan treatment group, SCr and BUN obviously decreased in the SG treatment group, but 24 h U-MA quantitation obviously increased (P<0.05). BUN obviously decreased in the combination of SG and telmisartan treatment group (P<0. 05).

CONCLUSIONThe combination of SG and telmisartan could decrease urinary albumin, and stabilize SCr levels.

Objective To explore the relationship between Wuyishan cliff tea and esophageal cancer,and make integrated measures to prevent and control esophageal cancer.Methods A case-control study was conducted with a ratio of 1 to 1 and a health survey was conducted on objects which included 92 cases with histologically confirmed diagnoses of squamous-cell carcinoma of the esophagus and 92 controls matched by age,sex and resident.The analysis method of conditional logistic regression was used to analyze the influence of cliff tea on the development of esophageal cancer. Results The frequency of cliff tea drinking was 73.91% in cases with esophageal cancer compared with 84.78% in controls. As compared with subjects without tea drinking,subjects with cliff tea drinking significantly decreased the risk for developing esophageal cancer (P<0.05),and its OR were 0.60.The risk of esophageal cancer significantly reduced with increasing frequency of cliff tea drinking per week. Furthermore, we also found that the risk of esophageal cancer significantly reduced with the duration of cliff tea drinking and the early of beginning to drink cliff tea.Conclusion Wuyishan cliff tea drinking may protect against the risk of esophageal cancer.

Objective To explore the therapeutic effects of statin in patients with chronic obstructive pulmonary disease (COPD) in stable period. Methods 83 patients with COPD in stable period were recruited and randomly divided into two groups, treatment group (n = 41) and control group (n = 42).The control group received conventional routine therapy, and treatment group was given rosuvastatin calcium 20 mg once per day on the basis of routine treatment. The levels of sera C-reactive protein (CRP), pulmonary function (FEV1、FEVl%pred), and COPD assessment test (CAT) were observed at the time points of 0 week and 12th week, 24th week and 48th week were compared between two groups. Results At 12th week after the treatment, sera CRP levels, FEV1, FEV1%pred and CAT scores in either control group or treatment group showed some extent of improvements as compared to those at the time point of 0 week, and there was statistical difference of sera CRP levels and CAT scores between two groups (P < 0.05). There was no statistical difference of FEV1, FEV1%pred between two groups (P > 0.05) .24th week and 48th week after the treatment; sera CRP levels, FEV, FEV1%pred and CAT scores in two groups all significantly improved and were statistical different between two groups (P < 0.05). Conclusion Statin can alleviate inflammatory reaction, improve pulmonary function and life quality of patients with COPD.

Background Light stimulation at different wavelength influences the development of eyes.It has been showed that blue light can inhibit the growth of eyeball.To study whether blue light exposure can delay the extension of myopia is an interested research project.Objective This study was to investigate the effect of blue light with short wavelength on ocular growth in form deprived myopia (FDM) in guinea pigs and provide a new option for the prevention and treatment of myopia.Methods Thirty-six 2-week-old guinea pigs were reared in the environment of white light.The right eyes of the animals were occluded to establish the FDM models.The models were randomized into the deocclusion + blue light exposure group,simple deocclusion group and continuous occlusion group according to the random number table.The right eyes of the models were deoccluded for 1 hour per day to give the blue light (430 nm) irradiation in the deocclusion + blue light exposure group,and the right eyes were deoccluded for 1 hour per day only in the simple deocclusion group.In the continuous occlusion group,the right eyes of the models were occluded until the end of this experiment.Anterior chamber depth (ACD),lens thickness (LT) and vitreous cavity depth (VCD) were measured by A-type sonography.The binocular diopter of the guinea pigs was detected using retinoscopy in the mydriatic condition.In the fourth week after experiment,the retinal sections were prepared for the regular histopathological examination,and the scleral tissues next to 1 mm from optical nerve were exacted to obtain the dry weight of scleral tissues.Results In the right eyes of the animals,no significant differences were found in the diopter,ACD,LT and VCD before experiment among the 3 groups (all at P＞0.05).At the end of experiment,the refraction of right eye in the deocclusion + blue light exposure group,simple deocclusion group and continuous occlusion group was (+1.11±0.17)D,(+0.90±0.15)D and (-2.73±0.19)D respectively,with a significant difference among them (F=1 445.470,P=0.000).The VCD in the three groups was (3.70±0.09) mm,(3.78±0.11) mm and (3.91 ± 0.08) mm,respectively,showing a significant difference (F =13.243,P＜0.01).In addition,the dry weight of sclera tissues was (0.61 ±0.09)mg in the deocclusion + blue light exposure group,(0.54± 0.08)mg in the simple deocclusion group and (0.43 ± 0.07)mg in the continuous occlusion group,with a significant difference among the 3 groups (F=10.458,P＜0.01).However,there were no significant differences in the ACD and LT among the 3 groups (F=0.203,0.084,both at P＞0.05).Moreover,in the left eyes,no significant differences were found in the diopter,ACD,LT and VCD before experiment among the 3 groups (all at P＞0.05);while at the end of the experiment,the diopter of the continuous occlusion group was significantly lower than that of the deocclusion + blue light exposure group and simple deocclusion group (all at P＜0.05).No significant differences were seen in the ACD,LT,VCD and dry weight of sclera among the 3 groups (all at P＞0.05).Retinal structure was normal in the left eyes of various groups.However,the retinas were thinner in the right eyes of the deocclusion + blue light exposure group with clear layers; while atrophy of the outer segment of photoreceptor and disorder of cell arrangement were seen in the right eyes of the continuous occlusion group.Conclusions During sensitive period of visual development,blue light stimulation can arrest the extension of posterior sclera and elongation of vitreous cavity,which restrains development of myopia.This blue light at the wavelength of 430 nm is safe to retina.
