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.

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.

[Objective] To evaluate the effect of Tiepi Fengdou Granule(TFG) as adjuvant treatment in cancer patients during chemotherapy.[Methods] Twenty patients were treated with TFG,and then we added up integral calculus of Yin Deficiency symptoms,tested blood routine,hepatic and renal function and subgroup of T-cell and NK cell.[Results] The Yin Deficiency symptoms of 7 cases(35%) were improved significantly,and 13 cases were partly improved(65%).Each integral calculus of Yin Deficiency symptoms was descended.The tested blood routine,hepatic function and subgroup of T-cell and NK cell were changed significantly.[Conclusions] TFG could control the symptoms of Yin Deficiency and improve immune function for cancer chemotherapy patients.

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.

BACKGROUND:Bone marrow mesenchymal stem cel s can migrate into tumor tissues, as reported in recent studies.
OBJECTIVE:To investigate the tropism and effect of transplantation of bone marrow mesenchymal stem cel s on proliferation and differentiation of gastric cancer cel line SGC7901 in rats.
METHODS:Gastric cancer models were established in Sprague-Dawley rats by subcutaneous injection of gastric cancer cel line SGC7901, and then, in cel transplantation group, each rat underwent an intraperitoneal injection of 1×107 bone marrow mesenchymal stem cel s. After transplantation, the targeting ability of bone marrow mesenchymal stem cel s was detected using fluorescent DiI labeling. Cyclin D2 mRNA and protein expressions were measured using real-time PCR and western blot assay, respectively. Apoptosis of gastric cancer cel s was observed by in situ terminal labeling method.
RESULTS AND METHODS:Bone marrow mesenchymal stem cel s successful y migrated into the gastric cancer site in rats. The expression levels of cyclin D2 mRNA and protein in the cel transplantation group were significantly higher than those in the model group (P<0.05). It was observed that the number of apoptotic cancer cel s was significantly reduced in the cel transplantation group compared with the model group (P<0.05). These findings indicate that bone marrow mesenchymal stem cel s have the ability to migrate into the tumor sites, thereby promoting the proliferation of gastric cancer cel s.

Objective To study the relationship between the co‐expression levels of inducible costimulatory molecule (ICOS)and CD28 on peripheral blood CD4+ and CD8+ T cells and Behcet’s disease(BD).Methods Flow cytometry was used to detect the expression levels of ICOS and CD28 on peripheral blood CD4+ and CD8+ T cells of BD patients(n=22) ,including those with active BD(ABD ,n= 14)and stable BD(SBD ,n= 8) ,and of normal subjects(n= 22).Results The proportion of CD28+ ICOS+ CD4+ T cells was significantly increased in ABD patients when compared with normal subjects [(34.72 ± 12.87)% vs.(25.36 ± 8.24)% ,P<0.05].No significant difference was found in the proportion of CD28+ ICOS+ CD8+ T cells [(9.32 ± 4.57)% vs.(7.24 ± 3.36)% ,P>0.05]between the two groups.The proportions of CD28-ICOS+ CD4+ T cells and CD28-ICOS+CD8+ T cells were both obviously increased in ABD patients when compared with those in normal subjects[(2.54 ± 1.63)% vs.(0.76 ± 0.25)% for CD28- ICOS+ CD4+ T cells ,P< 0.05;(8.79 ± 3.41)% vs.(3.04 ± 1.25)% for CD28-ICOS+CD8+ T cells ,P<0.05].Conclusion The increased expression level of ICOS on peripheral blood CD4+ and CD8+ T cells is not closely associated with the expression of CD28 to some extent in BD patients ,suggesting that cells expressing only ICOS play an important role in the development of BD.

Objective To investigate the expression differences of β‐catenin ,Her‐2/Neu and ki‐67 in different pathological features of gastric cancer and their role in the occurrence ,progression ,invasion and metastasis of gastric cancer invasion and metas‐tasis .Methods The expression of β‐catenin ,ki‐67 and Her‐2/Neu in 150 gastric cancer tissue samples(observation group) and 70 normal gastric mucosal samples were detected by adopting the immunohistochemistry method ,and the relationship between the ex‐pression of β‐catenin ,ki‐67 and Her‐2/Neu with the pathological features of gastric cancer was analyzed .Results Theβ‐catenin ,ki‐67 and Her‐2/Neu positive rate in the observation group was significantly higher than that in the control group (χ2 =30 .51 ,63 .74 , 11 .38 ,P<0 .01);the differentiation degree affected the expression of β‐catenin ,ki‐67 and Her‐2/Neu expression (χ2 =15 .82 ,8 .61 , 8 .11 ,P<0 .01);the lymph node metastasis affected the expression of ki‐67 and β‐catenin (χ2 = 6 .26 ,P< 0 .05;χ2 = 7 .36 ,P<0 .01);the invasion depth affected the expression of β‐catenin and ki‐67(χ2 =11 .34 ,P<0 .01);TMN affected the expression of ki‐67 and Her‐2/Neu(χ2 = 10 .85 ,14 .24 ,P< 0 .01);the β‐catenin and ki‐67 expression showed positive correlation .Conclusion β‐catenin ,ki‐67 and Her‐2/Neu may reflect the proliferation ,invasion and metastasis situation of tumor cells and their detection con‐duces to the judgment of prognosis .

Anaplastic thyroid cancer (ATC) is a rare but highly lethal form of thyroid cancer.The original ATC guidelines were published by American Thyroid Association in 2012.The guidelines recommend that once the diagnosis of ATC has been verified,rapid evaluation and establishment of treatment goals are imperative,and a multidisciplinary management is required.Radical surgical resection and high doses of external beam radiotherapy are important factors associated with prolonged survival.
