Objective To study the effects and the therapeutic mechanism of Humulus scandens particles ( HSP ) on the mice with chronic bronchitis ( CB ) . Methods Mice were divided into normal control group, dextromethorphan group or ammonium chloride group, the high-, middle-and low-dose of HSP groups ( These three groups received gavage administration of HSP at 3.00 g??kg-1, 1.50 g??kg-1 and 0.75 g??kg-1,respectively) randomly.The effects of HSP on ammonia-induced cough and trachea phenol red excretion in mice were observed.CB mouse model was established by inhaling smoke and formaldehyde.In total, 60 mice were divided into 6 groups by the method of random digits table: normal control group, model control group, Guilong kechuanning capsule group, the high-, middle-and low-dose HSP groups (n=10 each group).After modeling for 18 days, mice in normal control group and model control group were administered intragastrically with 0. 9% sodium chloride solution. Mice in the high-, middle-and low-dose HSP groups were daily treated with HSP at 3.00, 1.50 and 0.75 g??kg-1 ,respectively, by intragastric administration.Mice in Guilong kechuanning Capsule group were administered with Guilong kechuanning Capsule (600 mg??kg-1), once a day, for 15 days.The tumor necrosis factor alpha ( TNF-α) & interleukin-8 ( IL-8) contents in lung tissues of each group were determined. Results By hematoxylin-eosin (HE) staining, it was found that HSP alleviated the damage of CB in mice.The frequency of cough in 2 min in the normal control group, the high-, middle- and low-dose HSP groups were (17.50±5.38), (11.90±4.46), (12.60±3.47), (9.50±3.24), respectively, and the ecretion of phenol red were (0.52±0.11), (0.65±0.15), (0.64±0.14), (0.67±0.19) μg??mL-1, respectively.The content of TNF-α in lung tissues of the normal control group, model control group,the high dose HSP group was (25.8±6.9), (66.3±11.7), (43.5±7.7) ng??mg-1, respectively.The content of IL-8 in lung tissues of the normal control group, model control group, the high-dose HSP group were (27.1±9.1), (48.2±11.4) and (36.5±8.2) ng??mg-1, respectively.The contents of TNF-α and IL-8 in lung tissues of the model control group were significantly higher than those in normal control group (both P<0.01).Compared with the model control group, high-dose HSP could obviously decrease the contents of TNF-α and IL-8 in lung tissues (P<0.01 or P<0.05). Conclusion HSP can obviously alleviate the pathomorphological changes in mice with CB and has antitussive and expectorant effecs.The therapeutic mechanism of HSP for CB may be related to decreasing the contents of TNF-αand IL-8 in lung tissue.

Objective To observe the effect of the reinforcing kidney,nourishing and activating blood on promoting ovulation and improving the endometrium thickness and pregnancy rate in the process of in vitro fertilization-embryo transplantation(IVF-ET).Methods The 63 cases receiving IVF-ET were randomly divided into two groups: the treatment group(n=31) treated with GnRHa/r-FSH/HMG/HCG combined with the herbs of kidney-reinforcing,blood-nourishing and blood-activating in different periods of IVF-ET,and the control group(n=32) with GnRHa/ r-FSH/HMG/HCG alone.The dose of gonadotropin(Gn),endometrium thickness,follicular oocyte number,high-quality oocyte rate,fertilization rate,high-quality embryo rate and pregnancy rate of both groups were observed.Results In the treatment group,Gn dose was significantly lower(P

In this paper, the advances of the treatment for the most common pulmonary mycosis is introduced, and the recommended medications described. It is indicated that amphotericin B is still the first choice for the treatment of severe and rapidly progressive pulmonary mycosis. Lipid formulations of AmB can be used for those refractory or intolerant to the conventional amphotericin B. Fluconazole has proved effective in treating pulmonary candidosis, cryptococosis and coccidioidomysis. Itraconazole has been widely used in the treatment of pulmonary aspergillosis, histoplasmosis ans coccidioidomycosis.

Elderly individuals make up a considerable large part of the breast cancer population.There are many different biological and pathological characteristics for this population as compared with the younger ones.Evidences on the treatment of elder patients with breast cancer are scarce.This article reviews the studies in the treatment and provides suggestions for the care of elder women with breast cancer.

Objective To develop and verify a multiplex fluorescence quantitative PCR(Taqman probe) method for the detection of telomerase activity.Methods Specific reverse transcription primers,two pairs of quantitative primers and probes were designed for the CDS sequence of telomerase catalytic subunit telomerase reverse transcriptase(TERT).After optimization of the reverse transcription primers(specific reverse transcription primers and random primers) and quantitative primers(two pairs of quantitative primer probes used alone or in combination) in the reaction system,with the primer probe of internal reference gene GAPDH,multiplex fluorescence quantitative PCR was performed in a single tube.In addition,telomerase positive standard and negative standard were prepared with 293T and MRC-5 cells respectively,and the stability and precision of the method were verified.The telomerase activity in 19 normal mesenchymal cell samples and 32 breast cancer cell samples were detected by the developed method.Results The optimum reaction system was as follows:using cDNA synthesized with specific reverse transcription primers as the template,2 pairs of quantitative primer probes of TERT gene were mixed with internal reference gene GAPDH primer probes for multiplex fluorescence quantitative PCR reaction in a single tube.After optimization,the sensitivity and TERT fluorescence signal quantity of the system were greatly improved,and the ΔRn was enhanced by 3 times.The amplification curve of positive standard TERT gene was normal,and the ΔCt between TERT gene and GAPDH gene remained stable.The amplification curve of GAPDH gene in negative standard was normal,while there was no amplification curve of TERT gene.There was a little difference in ΔCt between TERT and GAPDH genes in the positive standard frozen and thawed for 3 and 5 times repeatedly and the positive standard without freezing and thawing,and the CVs of precision in intra-and inter-groups were all less than 1%.Telomerase activity was negative in 19 normal mesenchymal cell samples and positive in 32 breast cancer cell samples,and significant difference in Ct value of TERT gene between them was observed(t=4.236,P <0.001).Conclusion The developed multiplex fluorescence quantitative PCR(Taqman probe) method for the detection of telomerase activity has good stability and precision,which is expected to be used in early diagnosis and gene therapy of tumors.

Objective To compare the effects of low-molecular-weight heparin (LMWH,fragmin) and aspirin versus aspirin alone on transient myocardial ischemia and in-hospital prognosis in patients with unstable angina pectoris (UAP).Methods A total of 86 patients with UAP were randomized into a group receiving aspirin (ASP group) a group receiving aspirin plus LMWH (fragmin group) for one week.Results The effective rate was 88.37% in the fragmin group and 67.44% in the aspirin group after one week (P

Objective To identify candidate regions of sporadic pheochromacytoma (PCC).Methods Totally 42 patients who were clinically diagnosed as sporadic PCC from 2011-9 to 2013-5 in PUMCH were enrolled .To extract whole genome DNA from their tumors as well as peripheral blood leukocytes and to exclude inherited cases by San-ger sequence mutation .Within 14 verified cases of sporadic PCC , we applyed single nucleotide polymorphism ( SNP) chip to detect whole genome DNA copy number variations ( CNV) and loss of heterozygosity ( LOH) to ini-tiallylocatethehotregions.FinallyapplyQ-PCRtoconfirmthehotregionsinleftcases.Results 38caseswere identified as sporadic PCC , and 4 as inherited cases .CNV were found in 14/14 tumors, of which deletions were more common.Missing regions occurred in 1p,3q,17p,22q,11p.On the other hand, of the 3 inherited cases, de-letion was also detected.The loss of parts of arm 1p is the most common, including chr1:74 957 006 ~86 132 879 , chr1:58 096 424~67 700 471 , and chr1:98 902 091~107 622 430 .The result of Q-PCR confirmed the above-mentioned three regions , and the three segments are final candidate regions .Conclusions Partially de-letion of 1p in most cases is the most striking phenomenon , we believe that the deletion of 1p may occur with PCC development , and there may be some tumor suppressor gene ( s) within these areas .

BACKGROUND:Currently, the implant surface is optimized to promote the osseointegration of artificial dental implants, which has become a research focus in recent years. But the femtosecond laser is less reported to modify the titanium surface so as to promote fibroblast proliferation and differentiation. OBJECTIVE: To observe the effect of femtosecond laser on the proliferation and differentiation of human periodontal ligament fibroblasts on titanium surface. METHODS: Human periodontal ligament fibroblasts were respectively inoculated on different titanium surfaces of the three groups (femtosecond laser group, TiO2 particle blasted group and pure titanium group). Then differentiation and proliferation of human periodontal ligament fibroblasts were observed. RESULTS AND CONCLUSION:There was a significant difference in the surface roughness among these three groups, and compared with the pure titanium group, the attached cels were more in the femtosecond laser group and TiO2 particle blasted group. mRNA expressions of RUNX2 and OSX were highest in the femtosecond laser group folowed by TiO2 particle blasted group and pure titanium group in order. These findings indicate that pure titanium treated with femtosecond laser has fine biological property and may be more feasible for human periodontal ligament fibroblasts to attach, grow and proliferate.

Acute leukemia is a common malignancy tumor in children. Hemorrhage is one of the common symptoms and causes of death. The abnormality of platelet count, quality and function can cause bleeding. The understanding of platelet function and platelet parameters can provide an important clinical information for children with acute leukemia in evaluating the effect of treatment,the function of bone mar-row and the prevention of bleeding and so on.
