OBJECTIVETo compare the effects between mild moxibustion and specific electromagnetic spectrum therapy apparatus (TDP) for obsolete collateral ligament injury of interphalangeal joints.

METHODSSixty patients were randomly divided into a mild moxibustion group and a TDP group, 30 cases in each one. In the mild moxibustion group, pure moxa sticks were used at the affected digital joints locally for 20-30 min a time. In the TDP group, TDP was applied at the affected digital joints locally for 20-30 min a time. The treatment was given once a day for two courses, and 10-day treatment was made into a course. Visual analogue scale (VAS) for pain, swelling degree of the affected digital joints before and after treatment were observed and the clinical efficacy and safety were evaluated in the two groups.

RESULTSThe excellent rate was 56.7% (17/30) and the excellent and, good rate was 83.4% (25/30) in the mild moxibustion group,which were better than 36.7% (11/30) and 76.7% (23/30) in the TDP group respectively (both P < 0.01). After treatment the score of VAS and digital joints swelling degree were improved than those before treatment in the two groups (P < 0.01, P < 0.05), and the improvements of the mild moxibustion group were better than those of the TDP group (P < 0.01, P < 0.05).

CONCLUSIONMild moxibustion can apparently relieve the painful and swelling degree of obsolete collateral ligament injury of interphalangeal joints, which is superior to TDP.

Objective To evaluate laparoscopic local resection for the treatment of gastric tumors. Methods The clinical data of 78 patients who received laparoscopic local resection at the PLA General Hospital from February 2006 to January 2010 were retrospectively analyzed. According to the tumor site and free range, total laparoscopic gastrectomy was applied to 45 patients, laparoscopic local resection was applied to 22 patients, laparoscopic and endoscopic tumor resection was applied to 11 patients. The efficacies of the surgical approaches were investigated. Results Laparoscopic local resection was successfully performed on the 78 patients without conversion to open surgery. The mean operation time and operative blood loss were 75 minutes (range, 45-120 minutes) and 60 ml (range, 35-90 ml), respectively. The mean diameter of the tumor was (2.5±1.3)cm (range, 0.7-4.8 cm). No mortality or morbidity occurred postoperatively. The bowel function recovery time and the duration of hospital stay were 35 hours (range, 25-42 hours) and 7.5 days (range, 6-9 days), respectively. The results of postoperative pathological examination verified that 63 patients were with gastric stromal tumor, 11 patients were with benign gastric diseases, including 5 with gastric heterotopic pancreas, 2 with inflammatory pseudotumor, 2 with hyperplastic polyp, 1 with schwannomas and one with angioma. Four patients were with carcinoid, 3 carcinoids were located in mucous layer and 1 invaded into muscular layer. The median time of follow-up was 26 months, and no anastomotic stenosis or port-site metastasis was observed. Of the 63 patients with gastric stromal tumor, 2 were treated with imatinib mesylate, 1 had tumor recurrence and received reoperation. Conclusion Laparoscopic local resection is safe and feasible for the treatment of benign gastric neoplasms, stromal tumor and early gastric tumors.

Polymeric micelles which are self-assembled from amphiphilic copolymers are thermodynamically stable, and they can solubilize hydrophobic drugs by the hydrophilic core. Many excellent active compounds are confined because of general low oral bioavailability due to poor solubility. Take into account from the two points above, polymeric micelles may be used as proper oral carrier to improve the dissolubility of hydrophobic drugs, and enhance the permeation though gastrointestinal tract, therefore, the pharmacodynamics is elevated. Meanwhile, the segments in copolymers are multivariate, so many kinds of micelles can be obtained, such as, pH- or thermo- sensitive as well as mucoadhesive ones. The modified micelles can alter drug release profiles while solubilizing them, that is why the oral bioavailability increase further. In this review, recent progress of polymeric micelles used in oral administration is summarized, and the prospect of polymeric micelles' application in this field is also evaluated.

BACKGROUNDHyperglycemia in brain and spinal cord could aggravate neurologic impairment. Recent studies showed that L-lysine monohydrochloride (LMH) could increase the insulin secretion and regulate the blood glucose level. The aim of the present study was to investigate the effects of LMH on pancreatic islet B cells, the levels of endogenous insulin and blood glucose in spinal cord injured rats.

METHODSForty male Wistar rats were divided into four groups, namely, normal control group, model group, high-dose LMH group (621.5 mg/kg equal to LMH 1/8 LD50), and low-dose LMH group (310.8 mg/kg equal to LMH 1/16 LD50). The model of spinal cord injured rat was established by hemi-transection at the lower right thoracic spinal cord. LMH was administered via intraperitoneal injection once spinal cord injury was produced in rats. All rats were sacrificed 48 hours after spinal cord injured. The effects of LMH on pancreatic islet B cells, the content of endogenous insulin, and the level of blood glucose were observed with immunohistochemical method, radioimmunoassay method, and biochemical analyzer, respectively.

RESULTSThe insulin immunohistochemical intensities of islet B cells were significantly weaker in model group than those in normal control group (P < 0.01). The levels of endogenous insulin were significantly lower and the blood glucose levels were significantly higher in model group than those in normal control group (P < 0.01). The insulin immunohistochemical intensities of islet B cells were significantly stronger in high-dose LMH group than those in model group (P < 0.05). In addition, we found that the levels of endogenous insulin were significantly higher and the blood glucose levels were significantly lower in high-dose LMH group than those in model group (P < 0.05). There were no significant differences in the insulin immunohistochemical intensities of islet B cells, the levels of endogenous insulin and the blood glucose between low-dose LMH group and model group (P > 0.05).

CONCLUSIONLMH, but dose-dependent, might participate in the regulation of pancreatic islet B cells, and then reduce the blood glucose levels in the spinal cord injured rats.

Objective To investigate the risk factors of schistosomiasis transmission in Jingmen City. Methods The Onco-melania hupensis snails,the wild animal feces,and infection source were selected as the monitoring objects to carry out the schistosomiasis risk monitoring. I-III levels of risk environments were treated with appropriate measures. Results A total of 52 environments and three water systems were monitored and 1542 snails were dissected but no Schistosoma infected snails were found. Nine fecal samples were collected from the areas with snails,and no eggs of Schistosoma were found. Eighty-nine samples of cattle/sheep faces,and mice and dogs were collected,and three samples of cattle feces were found with Schistosoma eggs. Five environments were assessed as Grade II,and 48 environments were assessed as Grade III,and 2 environments were as-sessed as no risk of schistosomiasis transmission. Conclusions In Jingmen City,the mollusciciding work from May to June could decrease the density of snails and the risk of schistosomiasis transmission efficiently. The schistosome-infected cattle were the main infection source,and therefore,the cattle and snails should be administrated simultaneously.

Objective To assess the prevalence of dyslipidemia among children and adolescents aged 6-18 years in Yinchuan.Methods A stratified,random cluster sampling was used to select a target samples (1 939 cases) of children from elementary schools,middle schools and high schools in different age groups,with medium economic status.The levels of serum total cholesterol (TC),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),and triglycerides (TG) were measured.Results The prevalence of total dyslipidemia was 15.5 ％ (300/1 939 cases).The prevalence of high TG,high TC,high LDL-C,low HDL-C,high non-HDL-C and hyperlipemia were 5.8％ (113/1 939 cases),0.8％ (18/1 939 cases),1.1％ (21/1 939 cases),10.6％ (205/1 939 cases),0.9％ (18/1 939 cases) and 6.4％ (124/1 939 cases),respectively.Boys were more likely to have dyslipidemia than girls (17.7％ vs.13.3％) and a low HDL-C level (13.1％ vs.8.2％),and the differences between 2 groups were statistically significant (x2 =7.178,P =0.007;x2 =12.337,P ＜ 0.001).Individuals aged 16-18 years had the highest prevalence of total dyslipidemia [19.1％ (89/466 cases)] than other age groups,and the difference was statistically significant(x2 =11.393,P ＜ 0.01).Prevalence of dyslipidemia among the obese,the overweight and the normal weight individuals were 39.7％ (69/174 cases),20.8％ (60/289 cases) and 11.6％ (171/1 469 cases),respectively.Moreover,prevalence of dyslipidemia increased significantly with gravity of obesity,and the difference was statistically significant(x2 =100.180,P ＜ 0.01).Individuals with abdominal obesity had higher prevalence rates of dyslipidemia than that of the non-abdominal obese individuals [31.5％ (92/292 cases) vs.12.6％ (207/1 064 cases)],and the difference was statistically significant (x2 =67.578,P ＜ 0.01).Approximately 39.7％ (69/174 cases) and 31.5 ％ (92/292 cases) obese individuals and abdominal obesity were candidates for taking intervention measures including nutritional counseling,school-based lifestyle as well as community fitness programs.Conclusions Screening and prevention should be regarded for dyslipidemia among children and adolescents,especially for boys and teenagers in Yinchuan.

OBJECTIVETo improve the surgery results and living quality of patients following the operation of the combined approach of tympanoplasty and mastoidectomy with close technique.

METHODSThe clinical data and following-up results of 49 patients treated with combined approach of tympanoplasty and mastoidectomy with close technique and 82 patients treated with open mastoidectomy with tympanoplasty were retrospective analyzed.

RESULTSIn the group treated with combined approach tympanoplasty, all patients got dry ear in 20 days and 31 patients' hearing level enhanced over 15 dB after the operation; but in the group treated with open mastoidectomy with tympanoplasty, only 13 patients got dry ear in 20 days and no patients' hearing level enhance over 15 dB after the operation. Although the recurrence rates between two groups were not significant difference, the patients of former group not only took a shorter recovery time and got a better hearing recovery, but also kept a normal external auditory meatus, at the same time, they need not to clear scab at fixed period all life long.

CONCLUSIONSWhen performed on carefully selected patients, combined approach tympanoplasty was a feasible surgical method to improve the surgery results and living quality of patients following the operation, however, the advanced equipment and perfect operation skill are necessary.

OBJECTIVETo investigate the impact of occupational stress on serum monoamine neurotransmitters in nurses.

METHODSA total of 131 nurses were included as study subjects by stratified cluster sampling. The occupational health information collection system (based on the Internet of things) was used to measure occupational stress. Serum levels of monoamine neurotransmitters were also measured.

RESULTSEpinephrine (E) was negatively correlated with superior support (P < 0.05) and colleague support (P < 0.05). Negative correlation was also found between dopamine (DA) and job prospect (P < 0.05). Level of 5-hydroxytryptamine was negatively correlated with promotion opportunities (P < 0.05). Norepinephrine (NE), E, and DA were all negatively correlated with work satisfaction (P < 0.05) and positively correlated with daily stress (P < 0.01). NE and E were negatively correlated with sufficient confidence (P < 0.05) and positively correlated with physical complaints (P < 0.01). There was a negative correlation between NE and psychological satisfaction (P < 0.05).

CONCLUSIONOccupational stress in nurses is correlated with serum monoamine neurotransmitters, and it may affect serum levels of monoamine neurotransmitters to a certain extent.
