OBJECTIVEThis study aimed to explore the differences of membrane thickness and pressure on the paranasal sinus membrane in goats and analyze their causes. The results can provide theoretical basis and guidance for the issues of the maxillary sinus floor augmentation related to the membrane.
METHODSThe membrane was cut into two sizes from every sinus membrane. The membrane was fixed in formalin to obtain tissue specimens for the membrane thickness study and pressure study. The correlation between the two parameters was then analyzed, and appropriate statistical methods and software were selected.
RESULTSThe top of maxillary sinus, the bottom of maxillary sinus and the frontal sinus membrane thickness were (410.03 ± 65.97), (461.33 ± 91.37), (216.90 ± 46.47) µm. The pressure were (260.08 ± 80.12), (306.90 ± 94.37), (121.72 ± 31.72) kPa. The mean differences of the membrane thickness between the top of the maxillary sinus and the frontal sinus, bottom and frontal, and top and bottom were statistically significant (P < 0.05). The mean differences in membrane pressure were also statistically significant (P < 0.05).
CONCLUSIONThe membrane thickness and pressure of the top and bottom of the maxillary sinus are higher than those of the frontal sinus membrane. However, the thickness and pressure of the bottom membrane are slightly higher than those of the top membrane. Pressure and membrane thickness are positively correlated in the sinus membrane.

Objective To investigate the molecular mechanism of retinoic acid in targeted treatment of craniopharyngioma by detecting the expression of RARαand PPARβ/δin craniopharyngioma cells and analyzing the correlation between the expression and effect of retinoic acid. Methods The expression of RARα and PPARβ/δ in craniopharyngioma cells from 31 patients cultured in vitro was quantified by reverse transcription-PCR. The inhibition rates of RA on craniopharyngioma with different expression of RARα and PPARβ/δ were detected by using MTT assay, and the correlation between the expression of RARα and PPARβ/δand the effect of RA was analyzed. Results 1. The RT-PCR results showed that the expression levels of PPARβ/δand RARα mRNA were different. Craniopharyngioma cells from 31 patients in primary culture were divided into three groups according the expression levels of nuclear receptor: PPARβ/δ>RARα group, RARα>PPARβ/δ group and RARα>>PPARβ/δ group. 2.MTT results showed that the inhibition rate of RARα>>PPARβ/δgroup was significantly higher than the other groups under same drug, the differences had statistical significance ( <0.01) . Conclusions The expression of PPARβ/δ, RARα can be used to evaluate the effect of RA in treatment of craniopharyngioma. The craniopharyngioma with low-expression of PPARβ/δ is more sensitive to RA. Targeting higher RARα or targeting lower PPARβ/δ is beneficial to the treatment of craniopharyngiomas.

Abstract: The loop-mediated isothermal amplification (LAMP) technique is a technique for the specific and efficient amplification of target fragments at a constant temperature using two pairs of specially designed primers and a strand displacement activity DNA polymerase. LAMP technique is a simple, rapid, specific, sensitive and cost-effective nucleic acid amplification method, and therefore has a promising future in the field rapid detection of Mycobacterium tuberculosis and grassroots applications. In this review, the basic principles and characteristics of the LAMP technique, the main molecular markers for the diagnosis of tuberculosis, and the use of different molecular markers and various types of novel techniques in the diagnosis of pulmonary tuberculosis, extrapulmonary tuberculosis, and drug-resistant tuberculosis were described. The LAMP technique has been widely used in the diagnosis of tuberculosis with high sensitivity and specificity, but the technique still has some shortcomings. This paper reviews the progress of its application in tuberculosis in recent years and provides an outlook on its development, with a view to providing a rational research direction for rapid diagnosis of tuberculosis in a resource-limited environment.

Background and purpose: The incidence of breast cancer increases as patients age, elderly patients account for a large proportion. Due to the insufifcient systemic therapy, more complications and poorly physical condition, the prognosis of elderly patients is often worse than the younger. The aim of this study was to investigate the safety and tolerance with non-anthracyclin regimen as adjuvant chemotherapy in elderly breast cancer patients. Methods:From Nov. 2008 to Jan. 2012, 56 patients (≥65 years) after surgical excision were enrolled into this study. The patients were divided into two groups:TC and PC groups. Each patient received 4 or 6 cycles of chemotherapy of PC (175 and 600 mg/m2, respectively;n=21) or TC (75 and 600 mg/m2, respectively;n=35), administered intravenously every 3 weeks, as adjuvant chemotherapy. Radiation therapy (as indicated) and endocrine therapy, for patients with hormone receptor-positive disease, were administered after completion of chemotherapy. Results: In this study, 50 patients completed chemotherapy as plan, the proportion of two groups were above 90%. After a median follow-up of 33 months, the median disease-free survival(DFS) and overall survival(OS) were not reached. The relapse-free rate and survival rate were 89.5%and 100%in the PC regime group, which were 90.3%and 96.8%in the TC regime group. Major toxicities included:neutropenia, leucopenia, alopecia, nausea, vomiting and various degree of peripheral neuropathy. The incidence of gradeⅢ-Ⅳneutropenia was 76.2%in PC group vs 48.6%in TC group (P=0.044). The most common cause for withdrawing from treatment was to be unable to tolerate the adverse effects. Conclusion:Adjuvant chemotherapy with paclitaxel and cyclophosphamide is safe, tolerable and promising for elderly breast cancer patients.

OBJECTIVE:
To investigate the effect of yizhi jiannao granule concentration fluid (YCF) on the behavior, the apoptosis rate of hippocampus neuron and the expression of apoptosis gene Bcl-2, Bax in senescence accelerated mice Senile-Prone/8 (SAMP/8), and to discuss some mechanism of traditional chinese medicine YCF in improving the capability of learning and memory.
METHODS:
Forty 6-month old SAMP/8 mice were randomly divided into the old group, huperzine A (Hup-A) group and YCF group. Ten 4-month old SAMP/8 mice were served as a young control group. Four groups were given different drugs for 8 weeks, their behavior changes were observed, and the hippocampus were taken out to examine the apotosis rate by flow cytomeutry (FCM) and the expression of Bcl-2, Bax mRNA by RT-PCR.
RESULTS:
In the YCF group, the escape latency was significantly shortened, the time of swim in the platform quadrant significantly increased, the apoptosis rate of hippocampus neural decreased; the level of Bcl-2 mRNA and the rate of Bcl-2/Bax increased, and the level of Bax mRNA decreased.
CONCLUSION
Yizhi jiannao granule can decrease the neuron apoptosis rate and the Bax level, increase the Bcl-2 level, and modulate the rate of Bcl-2/Bax in SAMP/8 brain, which is probably part of the mechanisms of inhibiting the apoptosis and improving learning and memory.
