Microorganisms can affect the development of body immune system.Intestinal flora regulate immune function by promoting the intestinal immune system development,inducing T cell differentiation to avoid or reduce the incidence of immune-related diseases.Allergic diseases are related with the body's immune system hypoplasia and imperfect immune regulation mechanism.The immune system can be affected by intestinal flora,and the distribution of flora in the body between children with allergies and healthy children are significantly different,indicating that the occurrence of allergic diseases are associated with intestinal microflora.Studies have reported probiotic are helpful to the prevention and treatment of allergic disease,providing a new way for the prevention and treatment of allergic diseases.

Based on clinical features of refractory diseases and clinical practice experience for many years,the author expounded the therapeutic strategies from establishing individualized system of differentiation treatment,treatment strategies of refractory diseases,and the key for medication,and emphasized individual concerned therapy,separating primary and secondary treatment and grasping the physiological state to treat pathological changes.Thus complicated and changeable diseases can be treated clinically.

Objective To study the chemical constituents from the fungal fruiting bodies of Ganoderma sinense.Methods Individual constituents,isolated and repeatedly purified on silica gel and Sephadex LH-20 column chromatography,were identified by physicochemical constants and structurally elucidated by spectral methods.Results Four compounds were isolated and identified as: sinensoic acid(1),cerebroside D(2),poke-weed cerebroside(3),hemisceramide(4).Conclusion Compound 1 is a new compound,others are isolated from the fungus of Ganoderma for the first time.

Objective To investigate the clinical value of negative pressure vacuum cushion combined with thermoplastic body membrane in radiotherapy for Wilms tumor in children.Methods A total of 42 pediatric patients with Wilms tumor who received radiotherapy after surgery were enrolled in the study and were randomly divided into two groups according to the fixation positions:group A and group B.During radiotherapy, the patients in group A were fixed with negative pressure vacuum cushion, and those in group B were fixed by negative pressure vacuum cushion combined with thermoplastic body membrane.The setup errors, short-term effects, adverse reactions, and prognosis were compared between the two groups.ResultsGroup B showed significantly lower translational errors and rotational errors, as well as significantly higher rates of ≤3 mm and ≤5 mm errors, compared with the group A (P=0.04,0.04,0.04,0.03,0.00,0.04,0.04,0.00,0.04).Group B also showed significantly higher complete remission rates and response rates than group A (P=0.02,0.04).There were no significant differences in the adverse reaction rates (P=0.75) and the overall survival (OS) rates at 2 and 3 years (P=0.68,0.74) between the two groups.Group A had the MPTV values in left-right (LR) direction (x-axis), superior-inferior (SI) direction (y-axis), and anterior-posterior (AP) direction (z-axis) being 5.74 mm, 5.93 mm, and 5.94 mm, respectively, and group B had the MPTV values at LR, SI, and AP directions being 4.21 mm, 5.71 mm, and 4.61 mm, respectively.Conclusions In the radiotherapy positioning for Wilms tumor in children, fixation limbs with negative pressure vacuum cushion combined with thermoplastic body membrane effectively reduces the setup errors and improves the effect of radiotherapy, so it holds promise for clinical application.

Allopurinol is a xanthine oxidase inhibitor,it can reduce production and excretion of uric acid and oxygen free radicals generation. Allopurinol has good therapeutic effects on gout and hyperuricemia,and can relief symptoms of prostatitis. In addition, allopurinol has protective effects on ischemical reperfusion injury,inflammation and tumor.

AIM: To investigate the effect of Guishen Capsule(Radix Angelicae Sinesis,Radix et Rhizoma Salivae Miltiorrhizae,etc) on mastoplasia and T-lymphocyte subsets of spleen in rats. METHODS: The model of mastoplasia was induced by benzoate estradiol intraperitoneal injection in SD female rats.The model rats were treated with low,middle and high dosages of Guishen Capsule,respectively.All rats were killed after 30 days,the tissue of second pair of mammary glands were observed.At the same time,the spleens were taken out for preparing single cells suspension.The ratio of CD~+_3,CD~+_4,CD~+_8,CD~+_4/CD~+_8 of splenic T-lymphocytes were determined by flow cytometry(FCM). RESULTS: Compared with normal group,the growth of weight was slow in model group,and its breast was swollen,and proliferation was obvious in mammary gland tissue,the ratio of CD~+_3,CD~+_4,CD~+_4/CD~+_8 reduced significantly in model group. Guishen Capsule could inhibit the breast swelling and mammary gland hyperplasia.It also could increase ratio CD~+_3,CD~+_4,CD~+_4/CD~+_8 of splenic T-lymphocytes remarkably. CONCLUSION: Guishen Capsule can inhibit mammary gland hyperplasia.It also has the function of immunologic enhancement and cellular immune regulation.

Objective To study the relationship between operative procedures and complication of colorectal carcinoma with acute colonic obstruction in the elderly patients. Methods 65 elderly patients undergoing emergency operation for acute colonic obstruction were analyzed retrospectively. One stage tumor resection and anastomosis was performed in 25 cases with right-side colonic lesion and in 26 cases with left-side colonic lesion, Hartmann operation in 8 cases, Dixon operation in 4 cases and proximal colostomy in 2 cases. Results In 65 cases, 13 cases of postopera-tive complications,the rate was 20.0% (13/65) ,which infected with toxic shock two cases,four cases of pulmonary infection,anastomotic leakage two cases, wound infection, split 2 cases, death three cases, the mortality rate was 4.6%. The rates of postoperative complications in right-side colonic lesion, left-side colonic lesion, Hartmann opera-tion and Dixon operation were 69.2% ,0,30.7% and 0 respectively(P < 0.05 ～ 0.01). Conclusion Acute obstruc-tion of colon cancer,the right-side colonic lesion were safe,feasible and few complications in colorectal carcinoma with acute colonic obstruction.

Objective To compare two types of digestive reconstruction and postoperative complications after total gastrectomy in patients with gastric carcinoma. Methods Roux-en-Y esophagojejunostomy and P-type Roux-en-Y esophagojejunostomy were performed in 50 patients with gastric carcinoma after total gastrectomy. The operating time and postoperative complications were observed. Results The gastrointestinal symptoms for Roux-en-Y esophagojeju-nostomy and P-type Roux-en-Y esophagojejunostomy serve as : diarrhea ( 11.8% and 12.1% ), dumping syndrome (3.9% and 3.3% ) and reflux esophagitis(5.9% and 6.0% ) ,the incidence of the difference was not significant ( than,P>0.05 ). The postoperative complications in P-type Roux-en-Y esophagojejunostomy( 13.1% ) slightly higher that Roux-en-Y esophagojejunostomy( 11.1% ) ,but the difference was not significant( P>0.05 ). Roux-en-Y esoph-agojejunostomy average operative time(3.1±0.3)h was significantly reduced than P-type Roux-en-Y esophagojeju-nostomy(3.7±0.2)h(t=3.35,P<0.05). Conclusion Roux-en-Y esephagojejunostomy and P-type Roux-en-Y esophagojejunostomy is a suitable type after total gastrectomy for patients with gastric carcinoma, but the former opera-tive time was shorter.
