Objective To investigate the immunomodulatory effect of black rice anthocyanin(BA) on biochemical indicators in blood and macrophages in rats.Method Twenty four female SD rats were randomly divided into 4 groups:control group,BA low,middle and high-dose groups(BAL 25;BAM 50;BAH 100 mg/kg bw).The control group was treated with normal saline,while BA groups were i.g.administered with defferent doses for 30 d.The blood biochemical indicators were detected by automatic biochemistry analyzer.The activities of lactate dehydrogenase(LDH),acid phosphatase(ACP),superoxide dismutase(SOD),and maleic dialdehyde(MDA) contents in peritoneal macrophage(PM) and alveolar macrophage(AM) were determined by biochemical methods.The ability of macrophages to phagocytose neutral red was measured by colorimetric method.Results The levels of urea nitrogen(UN),uric acid(UA),triglyceride(TG),total cholesterol(TC) and low density lipoprotein(LDL) in blood were reduced.The activities of ACP,LDH in PM were increased.and the activities of SOD in PM and AM were increased whereas MDA was reduced.The ability of PM and AM to phagocytose neutral red was strengthened significantly.Conclusion BA shows significant immunomodulatory effection blood biochemical indicators and macrophages in rats.

Objective: The primary aim of this research is to systematically sort out and analyze available documents for yang deficiency syndrome in traditional Chinese medicine, providing innovative ideas and methods for statistical study of yang deficiency syndrome. Methods: Based on the China National Knowledge Internet (CNKI) and Chongqing VIP databases, using "yang deficiency", "deficiency cold", and "patient" as keywords, we searched literature of clinical researches and used "ratio-comparison" and "integration-comparison" to analyze objective data after data preprocessing. Relative importance value of physiological and biochemical parameters were reflected by P value calculated by ratio-comparison or Q value by integration-comparison. Results: With calculation of relative importance values of clinical indicators among various systems, we got the ranking of relative importance of different indexes. Triiodothyronine and urine 17-hydorxycorticosteroid of endocrine system, immunoglobulin A of immune system, and the ratio of cyclic adenosine monophosphate to cyclic guanosine monophosphate, which had great |P| (or |Q|) values and negative P (or Q) values, had a clearly lower level in yang deficiency patients than in the control; hemorheological indicators such as plasma viscosity, whole blood reduced viscosity and erythrocyte electrophoresis time had small |P| (or |Q|) values. These indicators, however, showed less importance for reflecting yang deficiency. Conclusion: Ratio-comparison method and integration-comparison method employed in this study have merits of efficiency and robustness. After detailed compiling and mining of all available data, we have made reasonable advice on the most relevant index of yang deficiency for further study of the essence of this syndrome.

The theory of four properties (Qi) and five tastes (Wei) is the core of the property theory of Chinese materia medica. It is known that Qi and Wei are associated with the pharmacological effects (Xiao) of herbs. This study took records of all 365 Chinese herbs in Shennong's Classic of Materia Medica (Shennong Ben Cao Jing) as the data resource and established a three-dimensional data cube, in the purpose of finding out and analyzing the frequent patterns and valued association rules of Qi, Wei and Xiao based on Apriori algorithm. The results of this study may give rise to innovative ideas and methods in research of traditional Chinese materia medica.

Hydrocortisone-induced yang-deficiency animal model has now become the generally accepted model of yang deficiency. However, assessing the most appropriate dose of hydrocortisone is a long-term challenge. For analyzing the modeling dose, the authors have built several kinds of yang-deficiency models induced by hydrocortisone at different doses, and analyzed the experimental data with various mathematical statistical methods. In order to discuss the effects of the modeling dose on the basis of previous research, the authors introduced Ridit analysis.

Objective:This article was a retrospective analysis on the preoperative CT scan of fungal sinusitis patients.The non-distinctive clinic feature was suggested to improve the accuracy of preoperative diagnosis.Method:A retrospective analysis was made for 176 patients with fungal sinusitis,which were confirmed by postoperative pathologic disanosis from January 2000 to January 2008.Every patient was performed both CT examination and nasalendoscopy preoperatively. All patients underwent endoscopic sinus surgery and the lesions in sinus were cleared and confirmed fungal infection by pathology.Thirty-five cases fungal infection located in sphenoid sinus,84 cases in maxillary sinus,49 cases in both maxillary and ethmoid sinus,3 cases in all sinus,5 cases in both ethmoid and sphenoid sinus.There were 179 sinuses in 176 patients were infected. Result:This group totally had 175 cases(179 sides). One hundred and seventy-three cases had unibilateral lesion,3 cases had bilateral lesion. The CT scan showed non-distinctive features including unifom dense,uneven dense in the sinus and bone resorption of the inner side bone wall. Five cases in sphenoid sinus lesion were found calcification in CT scan but 8 cases didn't show such features.Among these cases. 5 cases showed uniforra.dense and 3 cases showed uneven dense. In 84 cases maxillary sinus lesion,there were 12 cases without distinctive change,among these cases,8 cases showed uniform derise,4 cases showed uneven dense and 5 cases had boRe resorption. In 49 cases both ethmoid and maxillary sinus lesion,13 cases didn't show distinctive change,among these cases,9 cases showed uniform dense,4 cases showed uneven dense and 6 cases had bone resorption. Five cases had calcification in the both sphenoid and ethmoid sinus. Totally 81.56% of these patients had calcification feature in the CT scan.Conclusion:The calcification in the lesion of sinus is usually featured as characteristic manifestation of fungal sinusitis. But in clinic,the calcification does not exit in some patient's CT scan. When being absent of the featured sign in CT scan,the fungal sinusitis have to be diagnozed by other detecting means,even postoperative pathology.

Objective To discuss the significance of acoustic rhinometry(AR) and rhinomanometry(RM) in the evaluation of surgical treatment of nasal septal deviation.Methods Fifty-one patients of nasal septal deviation were recruited,and seventy-two nasal cavities were tested(twenty-one patients with narrowing of double sides).Visual analogue scale(VAS) was used to estimate the degree of nasal obstruction.AR and RM were used to obtain the data of nasal airway resistance(NAR),nasal cavity 0-5cm volume(NCV0-5) and nasal minimal cross-sectional area(NMCA).The data were used to assess the airflow function of nasal cavity.Each patient was tested at the time both before surgery and 12 weeks after surgery.The pre-and post operative data were used to calculate paired t-test by SPSS 16.0,and to disclose the correlation among ?NCV,?NMCA,?NAR and ?VAS.Results The preoperative data showed that NCV0-5 was 4.07?0.91cm3,NMCA 0.33?0.08cm2,NAR 1.14?0.34kPa?s?L-1,and VAS 7.36?1.23;and the postoperative data showed that NCV0-5 was 7.29?0.68cm3,NMCA 0.56?0.08cm2,NAR 0.35?0.12kPa?s?L-1,and VAS 1.14?0.91.Significant differences existed in NCV0-5,NMCA,NAR and VAS(P

Objective To evaluate the effect of morphine exposure in the late pregnancy on the expression of 2B subunit-containing N-methyl-D-aspartate receptor (NR2B) in the nucleus accumbens of offspring rats.Methods Forty-eight Sprague-Dawley rats at 14 days of gestation,aged 16-20 weeks,weighing 400-600 g,were equally and randomly divided into control group (group C) and morphine group (group M).In group M,morphine was administered subcutaneously twice a day (9:00 a.m.and 5:00 p.m.) in the initial dose of 2 mg/kg followed by daily increment of 1 mg/kg until 6 mg/kg.The equal volume of normal saline was given instead of morphine in group C.Fifty offspring rats with similar body weight were selected from the two groups,and conventionally fed for 8 weeks.Thirty offspring rats were further selected,morphine 3 mg/kg was injected subcutaneously for 7 consecutive days,and then the rats underwent the conditioned place preference test to monitor the effect.The time spent in drug-paired side (gray area) was recorded at 24 h after the test.Ten offspring rats selected were sacrificed after the test,and the brain was removed.The nucleus accumbens was isolated for detection of the expression of NR2B by immunohistochemistry and Western blot.Results Compared with group M,the time spent in drug-paired side (gray area) was significantly prolonged,and the expression of NR2B in the nucleus accumbens was up-regulated in group C (P＜0.05).Conclusion The mechanism by which morphine exposure in the late pregnancy causes susceptibility to morphine addiction is associated with up-regulation of NR2B expression in the nucleus accumbens of offspring rats.

OBJECTIVE:To observe therapeutic efficacy and safety of S-1 capsules combined with recombinant human end-ostatin in the treatment of middle and advanced primary liver carcinoma. METHODS:Totally 94 patients with middle and advanced primary liver carcinoma in the First College of Clinical Medical Science of China Three Gorges university during Feb. 2012-Dec. 2014 were divided into combination group(48 cases)and control group(46 cases)according to random number table. Both groups were given S-1 capsules 40-60 mg orally within 30 min after breakfast and supper. Combination group additionally received Recom-binant human endostatin injection 150 mg added into 0.9%Sodium chloride injection 210 mL with portable micro pump for continu-ous pump of 120 h. A course involved 14 d treatment and 7 d interval. Short-term objective therapeutic efficacy,clinical benefit re-sponse (CBR) and ADR were evaluated after 2 courses. Disease progression time and average survival period were compared be-tween 2 groups. RESULTS:Objective response rate,disease control rate,disease progression time and average survival period of combination group were 14.6%,66.7%,(5.5 ± 1.3) months,(10.7 ± 3.8) months;those of control group were 8.7%,45.6%, (4.8±1.2)months,(8.9±3.3)months,with statistical significance between 2 groups(P<0.05). CBR rate of combination group (79.2%)was significantly higher than control group(52.2%),with statistical significance(P<0.05). There was no statistical sig-nificance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:S-1 combined with recombinant human end-ostatin show good therapeutic efficacy and tolerance for patients with middle and advanced primary liver carcinoma,and do not in-crease the incidence of ADR.
