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.

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.

The mechanism of antiarrhythmic effects of palmatine( Pal), an benzoquinolizine compound were studied in experimental animals.In the isolated guinea pig papillary muscles, Pal 50 ?mol/L markedly prolonged the functional refractory period(FRP)and decreased the automaticity induced by adrenaline, but exerted no effect on excitabj- iity and contractility of the muscles.Pal(10 ?mol/L ) prolonged both APD20 and APD90 of the action potential of guinoa pig papillary muscles. The Vmax was decreased at 100 ?mol/L Pal, but the action potential amplitude( APA ) and resting potential ( RP ) were unaltered.The antiarrhythmic action of Pal may be due to its ability to decrease automaticity and to proloagate FRP and APD of the myocardium.

[Summary ] Accumulating evidence showed the associations between subclinical hyperthyroidism or subclinical hypothyroidism and adverse health outcomes. The related guidelines could be very helpful in making treatment decisions. However, even within the reference range, thyroid function is associated with adverse health outcomes, such as atrial fibrillation, coronary artery disease, osteoporosis, and dyslipidemia. Also, there is limitation to use TSH value as intervention threshold by the influence of age and other diseases. In this regard, a grading system is proposed to diagnose thyroid dysfunction, and risk stratification according to individual TSH values and comorbidities would be constructed to evaluate the utility of treatment.

Calorie restriction has been in use since 1900s as a therapy for obesity and type 2 diabetes. There are many modifications and progress in the forms, indications, effects, and safety of calorie restriction following a history over 100 years. However, controversies also arise such as the effect between intermittent calorie restriction vs daily calorie restriction, low fat diet vs low carbohydrate diet and low calorie diet. Therefore, more evidence-based data from high quality studies as RCT trials are needed for determining the optimal individualized calorie restriction regimen. Furthermore, calorie restriction mimetics is recently becoming an exciting research field for scientists and companies.

Histamine H 1R antagonists are mainly administered to treat the diseases of hypersensitivity reaction. And histamine H 2R antagonists are mainly administered to treat gastroenteric diseases. But in recent years administered simultaneously H 1R and H 2R antagonists can enhance their effects. Combination of H 1R and H 2R antagonists has good therapeutic effect on hypersensitivity reaction, cancers, asthma, etc, and can eliminate side effects.

3cm than in the patients with the largerest dominant diameter≤3cm.Embolization with combination of PLE and GSP had improved the percentage of reduc- tion in myomas volume.Conclusion The factors affecting results include tumor size and location,using of GSP,and performing of bilateral embolization.
