OBJECTIVE:To improve the drug delivery procedures and reduce the defects occurred in drug delivery.METHODS:The five procedures of six sigma including defining,measuring,analyzing,improving and controlling were applied to improve the drug delivery in our hospital's single dose dispensing(UDD)center.RESULTS:Due to the application of the six sigma method,the defect rate of drug delivery dropped from 25.1%(before the initiation of the six sigma method)to 5%(after the initiation of the six sigma method),which was significant lower as compared before the initiation of the six sigma method.CONCLUSION:Six sigma method contributed to the reduction of defect rate of drug delivery,so it deserves to be widely used in each management link in UDD center so as to improve the quality of dispensing.

OBJECTIVETo explore the technical feasibility, safety, and short-term clinical efficacy of right-to-lateral approach in laparoscopic-assisted radical gastrectomy.

METHODSClinicopathological data of 178 gastric cancer patients undergoing laparoscopic-assisted radical gastrectomy, including 92 patients with right-to-lateral approach(R-LG group) and 86 cases with left-to-lateral approach (L-LG group), in our department from October 2010 to September 2013 were analyzed retrospectively. Short-term efficacy and complication morbidity were compared between R-LG group and L-LG group according to body mass index (BMI).

RESULTSFor those patients with BMI ≥ 24 kg/m², the R-LG group (35 cases) had shorter mean operation time, less intraoperative blood loss, shorter painkiller used time than L-LG group (31 cases)[(227 ± 17) min vs. (262 ± 23) min, (73 ± 9) ml vs. (84 ± 8) ml and (2.1 ± 0.1) d vs. (2.6 ± 0.4) d, all P<0.05]. The average time to ambulation and recovery time of peristalsis in the R-LG group were faster than those in L-LG group [(2.2 ± 0.2) d vs. (2.8 ± 0.6) d and (3.6 ± 0.3) d vs. (4.2 ± 0.5) d, all P<0.05]. The R-LG group had more dissected lymph nodes per patient (35 ± 4) than the L-LG group (30 ± 5) with significant difference (P<0.05). There were no significances in postoperative hospital stay, postoperative complication morbidity and hospitalization expenses between R-LG and L-LG group (all P>0.05). For those patients with BMI<24 kg/m², there were no significant differences in all above parameters between R-LG group (57 cases) and L-LG group (55 cases). No mortality and recurrence was observed during follow-up of 3 to 24 months.

CONCLUSIONRight-to-lateral approach in laparoscopic-assisted radical gastrectomy is a safe and feasible procedure, especially for the obesity patients, which can shorten the operation time, decrease intraoperative blood loss, lead to a faster postoperative recovery and harvest more lymph nodes as compared to L-LG procedure.

Objective:To explore the prevalence of gout and related factors in community population, thereby provide evidence for comprehensive prevention and control of gout in community.Methods:A stratified multi-stage cluster sampling was used to survey the permanent residents of 20 to 75 years old in the 3 selected streets (towns), univariate analysis was performed using logistic regression by SPSS statistical software.Results:The prevalences of hyperuricemia and gout were 9.82% and 5.75% respectively(male 18.88% and 7.94%, female 3.79% and 4.29%)in Jiading Shanghai. The positive rate of family history was 17.13%, and the relationship between family history and gout was significant( OR=3.140, 95% CI 2.365-4.169, P<0.01). Age( OR=1.034, 95% CI 1.021-1.047), body mass index ( OR=1.102, 95% CI 1.074-1.131), waist-hip ratio ( OR=4.876, 95% CI 1.153-20.622), sleep quality ( OR=1.310, 95% CI 1.159-1.480), other animal meat ( OR=1.117, 95% CI 1.007-1.240), fresh water fish ( OR=1.138, 95% CI 1.005-1.288), and processed meat ( OR=1.145, 95% CI 1.033-1.270) were closely related to gout ( P<0.05 or P<0.01). Sex, alcohol drinking, marine fish, and soybean milk/soymilk were related to gout ( P<0.05 or P<0.01), but showed a protective effect ( OR<1.000). Conclusion:Reducing uric acid production through less consumption of purine-rich food such as animal meat as well as processed meat and weight control would be helpful in preventing gout.

Objective:To analyze the dosage distribution and the frequency of each dosage of high-risk tablets in the hospitalized patients in a children's hospital,and study whether the existing specifications of high-risk tablets meet the pediatrics clinical needs. Methods:All the prescriptions including high risk tablets were analyzed from 2014 to 2016 in Shanghai children's medical center. The frequency of every dosage of every drug was analyzed,and the current specifications were judged according to the frequency. New specifications were proposed when the existing specifications did not match the clinical needs. The new frequency of the proposed speci-fications was re-accounted for all the three-year prescriptions in order to evaluate whether the proposed new specifications met the clini-cal needs. Results:Among the five kinds of high-risk oral tablets,methotrexate tablets and vitamin A acid tablets were in accordance with the actual clinical requirements. Mercaptopurine tablets should add two specifications including 12.5 mg and 17 mg,and warfarin sodium tablets should add one specification(1.25 mg). Hydroxyurea tablets(250 mg) and warfarin sodium tablets(1 mg) were rec-ommended used in the children's hospital. Conclusion:The existing specifications of high-risk oral tablets can't fully meet the clini-cal needs,therefore,specifications still needs to be adjusted.

Objective:To observe any effect of dry needling of myofascial trigger points on substance P and synaptophysin expression in the spinal dorsal horn.Methods:Sixty-four Sprague-Dawley rats were randomly divided into a control group ( n=16) and a model group ( n=48). Myofascial trigger points were induced in the model group by a blunt strike and eccentric running. That group was then randomly divided into a no-treatment group ( n=15), a massage group ( n=16), and a dry needling group (16 rats). The rats in the two treatment groups received 4 weeks of dry needling or Chinese massage. Pressure pain thresholds were recorded before the experiment and after the 4 weeks. The content of substance P and synaptophysin in the spinal dorsal horn were measured using immunoblotting and immunohistochemistry. Results:After the treatment 14 rats (93%) in the model group had trigger points, significantly higher than the 8 rats (50%) in the massage group and the 7 rats (44%) in the dry needling group. After treatment, the average pressure pain thresholds of the no-treatment and massage groups was significantly lower than the control group′s average, while the difference between the dry needling group and the control group was not significant. The average pressure pain threshold had improved significantly in the no-treatment group, the massage group and the dry needling group, and the averages of the massage group and the dry needling group were significantly higher than that of the no-treatment group. The level of substance P was significantly higher in the no-treatment group than in the other three groups and the ratio of substance P to Glyceraldehyde 3-phosphate dehydrogenase (GAPDH)was significantly higher. The substance P: GAPDH ratio of the massage group was significantly higher than that of the control group.Conclusions:Dry needling and massage are effective in relieving myofascial pain, at least in rats. Both can reduce the content of substance P in the spinal dorsal horn.
