Twenty cases of infantile eczema were treated by combination of Tuina therapy and Western medications, and 18 cases were treated by Western medications. The therapeutic effective rate was respectively 100% and 90.0% in the two groups, with a difference between them (P＜ 0.01).

For engineering an efficient butanol-producing Escherichia coli strain, many efforts have been paid on the known genes or pathways based on current knowledge. However, many genes in the genome could also contribute to butanol production in an unexpected way. In this work, we used Tn5 transposon to construct a mutant library including 1 196 strains in a previously engineered butanol-producing E. coli strain. To screen the strains with improved titer of butanol production, we developed a high-throughput method for pyruvate detection based on dinitrophenylhydrazine reaction using 96-well microplate reader, because pyruvate is the precursor of butanol and its concentration is inversely correlated with butanol in the fermentation broth. Using this method, we successfully screened three mutants with increased butanol titer. The insertion sites of Tn5 transposon was in the ORFs of pykA, tdk, and cadC by inverse PCR and sequencing. These found genes would be efficient targets for further strain improvement. And the genome scanning strategy described here will be helpful for other microbial cell factory construction.

Objective To study surgical techniques and clinical effects of minimally invasive excision of high rectal carcinoid tumors with anus preservation. Methods We conducted transanal local excision of rectal carcinoid tumors in 6 cases by using self-made proctoscope and laparoscopic instruments from August 2002 to January 2005. The tumors were located on the depth of 9~12 cm from the anal verge, and excision margin was 0.5~1 cm from the tumors. Results All the operations were performed successfully. A follow-up for 3~28 months (mean, 15 months) found no recurrence, metastasis, rectal stenosis, or other short- or long-term complications. The postoperative hospital stay was 3~6 days. No analgesics were required. Conclusions Transanal local excision of high rectal carcinoid tumors under proctoscope is safe, reliable, minimally invasive, and cost-effective.

Objective To establish rat heart failure(HF)model following myocardial infarction(MI)and then detect the possible cytokines expression levels at different HF groups,so to explore the development of cytokines levels during the progression of heart failure.Methods The model was established by ligature of the left descending coronary artery.The rats were assessed by echocardiography and cardiac catheterization before and after 4 and 16 weeks following coronary ligature.Serum levels of TNF-α and IL-6 were determined.Results ①Serum cytokines could not be detectable in sham group using ELISA Methods,while in operated group,the concentration of TNF-α and IL-6 were significantly higher,especially IL-6.②The diagnosis coincidence between echocardiography and hemodynamics was high.Echocardiography can be used as an invasive measure to assess cardiac function in rat heart failure models.Conclusion ①Cytokines content is higher in compensated compared with the other two groups,especially to the IL-6 expression.②Cardiac ultrasound can be used as a useful method in monitoring postinfarction heart failure rat model,especially as an invasive measure.It can provide us successive data of the model.

Objective To understand the etiology and clinical manifestation of malignant atrophic papulosis,to report the psychological care of one case with malignant atrophic papules,and patients to maintain a good psychological state.Methods Nursing measures such as strengthening skin care,reducing discomfort,avoiding aggravating the injury; attention to abdominal signs,detection of changes in disease condition,prevention of intestinal perforation,related medication education to increase medication compliance were given to this patients.Results The abdominal pain disappeared,lower limb muscle force recovered,and the patient was discharged after the disease condition was steady.Conclusions To patients with malignant atrophic papulosis,early detection and early treatment should be given to them.

Objective To study the significance of plasma homocysteine(Hcy),high sensitivity C-reactive protein(hs-CRP)and cardiac treponin T(cTnT)changes in the patients with coronary heart diseases(CHD).Methods From August 2012 to November 2013,240 patients with CHD in our hospital were collected as the CHD group and 250 individuals of healthy physical examination served as the control group.Serum Hcy,hs-CRP and cTnT were detected by using the enzymatic cycle assay,immune scatter turbi-dimetry and electrochemiluminescence assay respectively.The data were statistically analyzed by the SPSS software.Results The serum levels of Hcy,hs-CRP and cTnT in the CHD group were (24.89±17.78)μmol/L,(17.43±35.89)mg/L and (0.76±2.36) ng/mL respectively,which were significantly higher than those in the control group(P <0.001).Moreover,the positive rate of Hcy in the CHD group was the highest (81 .25%),followed by hs-CRP(64.58%)and cTnT (58.75%).Conclusion Hcy,hs-CRP and cTnT played important roles in the development and progression of CHD,so reducing Hcy level may be an important pathway for preventing and treating CHD.

Objective To evaluate the effects of different kinds of fluorides and their loading on the fluoride releasing characteristics of fluoride containing composite resins. Methods Two paste type of composite resin, containing NaF and K 2TiF 6 respectively, were prepared. The composite resins were based on Bis GMA/TEGDMA resin and loaded with fluoride at 5%, 10%, 15% and 20% by weight, and a non fluoridated composite resin was prepared as the control. Six standardized discs (6 mm?3 mm) were made of each material, and three discs of each material were stored in plastic vials containing 5 ml deionized water at 37 ℃ respectively and the others in artificial saliva. The water and the artificial saliva were changed every 24 hours. An ion selective electrode (9606BN Orion) connected to an ion analyzer (720A Orion) was used to determine the amount of fluoride released on days 8, 15, 22, 29 and 62. The data were analyzed using t tests. Results All of the fluoride containing materials demonstrated a higher fluoride release than that from non fluoride control materials. The composite resin containing NaF released significantly more fluoride than that of K 2TiF 6. All materials showed a significantly higher release of fluoride in water than in artificial saliva ( P

Objective To assess long-term outcomes of electrocoagulation for treating varicose veins of the lower extremities. Methods A retrospective review was made on clinical data of 426 cases of varicose veins of the lower extremities treatd by electrocoagulation from October 1996 to October 2001.Postoperative follow-ups were carried out with clinic checkups or questionnaires.Results Of the 426 cases,follow-ups for 4~9 years(mean,5.8 years) were completed in 364 cases(500 limbs) and a loss to follow-up was encountered in 62 cases,the follow-up rate being 85.4%.The cumulative rate of recurrent varicose veins was 10.4%(52/500),in which the recurrent varicose veins were cured with sclerosing agents in 50 limbs and with re-operations in 2 limbs.The relief rate of sensation of heaviness and tension was 95.1%(309/325).Accompanying venous ulcers in 20 limbs healed up within 2~8 weeks.The incidences of subcutaneous hematoma and saphenous nerve injury were 0.8%(5/594) and 1.2%((7/594),) respectively.Skin burns happened in 5 limbs(0.8%,5/594). Conclusions Electrocoagulation for varicose veins of the lower extremities is proved to be a novel minimally invasive method,with advantages of safety,effectiveness,low costs,and short hospital stay.
