Objective To explore the characteristics of childhood tuberculosis and recent advances in the diagnosis and treatment of this disease in order to improve its diagnosis and treatment. Methods Key words“child”“tuberculosis”“diagno-sis” and “treatment” were used to retrieve relevant literatures from Pubmed,Web of Science,CNKI and Wanfang databases.The literatures were reviewed and clinical experience summarized. Results Disseminated tuberculosis and extrapulmonary tubercu-losis were common in children with tuberculosis. It was difficult to collect with samples of diagnostic value for detection. There counterparts were no systematic diagnosis and treatment programs available for children with drug-resistant tuberculosis,and phar-maceutical dosage forms tailored for children were lacking. Conclusion Tuberculosis in children is more complex to diagnose and treat than in adult counterpart.Diagnosis of this disease relies on a variety of diagnostic methods.It's still challenging to control childhood tuberculosis.

Objective To investigate effects of combined use of glycogen synthase kinase (GSK) -3 inhibitor and fructose-1,6-diphosphate (FDP) on liver trauma in rats. Methods After crea-tion of liver trauma model in 49 Sprague-Dawley rats, 42 rats were randomly divided into control group (NaCl group), FDP group and FGI Group (FDP and GSK-3 inhibitor in combination group). Then, each group was randomly subdivided into pre-ischemia group and 4-hour reperfusion group on account of time point when animals were sacrificed before and after iachemia. The other seven rats set as sham operation group (SH group) were sacrificed at 4-hour reperfusion time point. The AST and ALT levels in hlood and glycogen content, SOD vitality and MDA content in liver tissues were determined. Results At pre-is-chemia time point, liver glycogen content in three groups was in order of control group < FDP group < FGI group (P <0.01). At 4-hour reperfusion time point, blood ALT and AST levels in four groups were in order of control group > FDP group > FGI group > SH group (P < 0.01), while SOD vitality in liver tissues of four groups was in order of control group < FDP group < FGI group < SH group (P < 0.01) and MDA content in four groups was in order of control group > FDP group > FGI group > SH group (P < 0.01). Conclusions Combined use of FDP and GSK-3 inhibitor can enhance the protective effect of FDP on liver rupture, as may relate to the mechanism that GSK-3 inhibitor can effectively enhance glycogen synthesis of FDP as substrate before liver ischemia so that the liver glycogen storage is increased in a short period of time and hence post-traumatic warm ischemia-reperfusion injury is alleviated in the liver of rats.

Objective To investigate the relationship between serum levels of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMP) and the mortality in patients with malignant middle cerebral artery infarction.Methods A total of 74 patients with malignant middle cerebral artery infarction (MMCAI) was assigned to research group,74 healthy volunteers were recruited to serve as healthy controls,and 242 patients with other cerebral infarction were recruited to serve as case controls.Quality-of-life questionnaire and clinical examination were used to collect the information of participants.Endpoint was 30-day mortality.Results The research group showed higher serum levels of MMP-9,MMP-10,and TIMP-1 relative to the case control group,and the case control group showed higher serum levels of MMP-9,MMP-10,and TIMP-1 relative to the healthy control group (P ＜ 0.05).Compared to survivor ones,non-surviving MMCAI patients showed lower Glasgow Coma Scale score (P ＜ 0.05),higher serum levels of tumor necrosis factorα (TNF-α),MMP-9,MMP-10,and TIMP-1 (P ＜ 0.05).Multiple logistic regression analysis showed that serum levels of TNF-α,MMP-9,MMP-10,and TIMP-1 were associated with 30-day mortality,and the OR were 1.09,1.18,1.13,and 1.32,respectively.Conclusions Serum levels of MMP-9,MMP-10,and TIMP-1 levels in MMCAI patients were associated with mortality,and could be used as an auxiliary index of mortality in MMCAI patients.

Objective To explore the relationship of gallbladder emptying function and its hemodynamics in diabetic patients. Methods Gallbladder volume ,emptying function and its arterial blood flow were measured by ultrasound. Results The gallbladder volumes of fasting (FV ) and postprandial (RV) increased and the ejection fraction (EF) of gallbladder was decreased in DM group than in NC group (P<0.01). In DM group ,the gallbladder artery’s resistance index (RI) was higher than in NC group [(0.61 ± 0.06) vs (0.70 ± 0.08)](P<0.01). Minimum diastolic blood flow velocity (Vmin) was lower than in NC group [(8.72 ± 1.43) vs (6.05 ± 1.89)cm/s](P<0.01). RI was associated with HbA1c (r= 0.827 ,P< 0.01) and LDL‐C(r= 0.820 ,P< 0.01). Conclusion Gallbladder emptying dysfunction in diabetic patients is associated with the hemodynamics of gallbladder.

Currently, histological and molecular methods are considered for the treatment of advanced non-small cell lung cancer (NSCLC). Single-agent epidermal growth factor receptor tyrosine-kinase inhibitors (EGFR-TKIs) and anaplastic lymphoma kinase in-hibitors (ALK-TKIs) have been used as standard first-line therapies for patients with active EGFR mutation and ALK rearrangement, re-spectively. However, to date, the single-agent EGFR-TKIs as the first-line therapy for patients with known EGFR mutations has been demonstrated to provide a prolonged progression-free survival but does not affect overall survival (OS). Physicians these days focus on improving the OS of patients with advanced NSCLC. To patients with EGFR mutation, combining and maintaining EGFR-TKIs with chemotherapy could be a promising approach. In this article, various ways of combining EGFR-TKIs with chemotherapy were explored.

OBJECTIVE: To investigate the molecular mechanism of Huanglian Jiedu Decoction (HLJDD), a traditional Chinese compound herbal medicine, in treating type 2 diabetes mellitus (T2DM) by observing its effects on glucose transporter 4 (GLUT4) protein expression and translocation in adipose and skeletal muscle tissues of rats with T2DM. METHODS: T2DM was induced in rats by intravenous injection of a small dose of streptozotocin (STZ, 30 mg/kg) plus high fat and high caloric laboratory chow. Then animals were divided into untreated group, aspirin-treated group and HLJDD-treated group. Normal rats fed with common chow were designated as normal control group. Ten weeks later, the oral glucose tolerance test (OGTT) was performed in all animals, and the changes of murine body weight, fasting blood glucose (FBG), fasting serum insulin (FINS) and the expression of GLUT4 protein in skeletal muscle and adipose tissues before and after insulin treatment were routinely determined. RESULTS: Compared with the untreated group, the result of OGTT of HLJDD-treated group was improved. The levels of the body weight and FBG were decreased, while the GLUT4 protein expression and translocation were elevated obviously. CONCLUSION: It is suggested by the present results that the therapeutic effects of HLJDD on T2DM might be related to its ability of increasing GLUT4 protein expression and translocation in adipose and skeletal muscle tissues of T2DM rats.

To investigate the effects of antisense oligonucleotides directed at TNF-? on the intracranial pressure following craniocerebral explosive injury. Eighteen dogs were randomly divided into artificial cerebrospinal fluid (ACSF) group, sense group and antisense group. Using the model of craniocerebral explosive injury, ACSF, the sense oligonucleotides to TNF-? and the antisense oligonucleotides to TNF-? were administered into cerebellomedullar cisterna before injury respectively in three groups, and then the intracranial pressure and contents of brain H 2 O in the bilateral hemispheres in three groups were compared. As compared with the ACSF groups and the sense groups, the contents of brain H 2 O in the antisense groups were significantly reduced( P

Objective This work aimed at study the rel ationship between the pathologicomorphological change of gastrocneminus muscle cells and deep venous insufficiency (DVI).Methods Patients with DVI in three different stage of developing process are grouped into early t eam?middle team and late team group ,each group consists of 9 cases.HE stain , special ATPase histoenzymic methds was quantitatively employed to study histo chemical cytomorphology of gastrocneminus and musculus sartorius specimens in th ose subjects.Results There is no significant difference of the pathologicomorphological change,either between early-stage group and mid-sta ge group or between early-stage group & mid-stage and control group.But there is significant difference comparing advanced stage group and early-stage group & m id-stage group or between advanced-stage and control group.Conclusion As the process of DVI develops,marked morphological degeneration can be found in gastrocneminus muscle cells.It could be regarded as the pathogenic fundament of impairment of calf muscle pump and development of DVI.

To find out the method of assessing the car-diac reserve function under the resting condition,we observed the changes of left ventricular con-tractility, relaxation and compliance, as well ascardiac pump function under the resting and over-loaded conditions with intact hearts of male rats invarious states of heart failure induced by variousadriamycin cumulative doses. The results of thepresent study indicated that the degree of my-ocardium injury was aggravated along with the in-crease of adriamycin cumulative doses. Mean-while, all of the parameters of left ventricular con-tractility, relaxation, compliance and cardiac re-serve function decreased significantly. However,the indexes of basic cardiac pump function in-creased to a certain extent because of the influenceof non-cardiac factors. The discriminant analysisshowed that the degree of heart failure assessed bymeans of the discriminant function, or synthesizingthe changes of left ventricular contractility, relax-ation and compliance under the resting condition,was almost consistent with that by means of thecardiac reserve function. In addition, the multipleregression indicated that the contractility, relax-ation and compliance had different effects on thecardiac reserve function, corresponding to the different states of heart failure.
