Objective To isolate the anti-tumor protein groups from Pinellia ternata rhizome and investigate the anti-tumor activity of these protein groups on Bel-7402 cell. Methods The total raw protein was isolated with sepharose column chromatography. Methyl-thiazolyl-tetrazolinm (MTT) was used to analyze the effect of Pinellia ternata Protein on inhibiting growth of tumor cells. Apoptosis was detected by flow cytometry (FCM). Results The 30% and 60% (NH4)2SO4 deposition part of total proteins from Pinellia ternata rhizome have no certain relationship between quantity and inhibitory action, but protein peak 3 eluted with 0.05 mol/L or 0.1 mol/L NaCl from 30% (NH4)2SO4 deposition part showed a effect of concentration depending. FCM analysis showed that the protein of 30% (NH4)2SO4 deposition part could induce apoptosis. Conclusion The 30% (NH4)2SO4 deposition part of total proteins from Pinellia ternata rhizome could significantly inhibit Bel-7402 growth and induce its apoptosis.

Objective To explore the therapeutic effect of Lingzhu Infusion and Shenqi Capsule sequential therapy in combination with clomiphene citrate(CC)for polycystic ovarian syndrome(PCOS).Methods The 90 PCOS cases in accordance with the enrol- ment standard were randomized into three groups.The treatment groupⅠwas treated with Lingzhu Infusion and Shenqi Capsule se- quential therapy,the treatment groupⅡwas treated with Lingzhu Infusion and Shenqi Capsule sequential therapy and CC,and the control group was treated with CC only.The therapeutic effect was evaluated after two courses of treatment.Results After treat- ment,the changes of TCM syndromes and serum sex hormone indices,ovulation rate and conception rate of the treatment groupⅡwere all superior to those of the treatment groupⅠand the control group.Conclusion The effect of treatment groupⅠis similar to that of control group.The effect of treatment groupⅡis better than that of treatment groupⅠand control group,getting a higher ovulation rate and pregnancy rate.

Farnesoid X receptor (FXR) belongs to the nuclear receptor superfamily. It is highly related to the formation of metabolic syndrome and the glucose homeostasis, and therefore represents an important drug target against metabolic diseases and diabetes. In recent years, great progress has been made in the agonists, antagonists, and crystal structures of FXR. The diverse FXR ligands and their structure-activity relationship are reviewed in this article. The advances in the crystal structures of FXR in complex with different ligands are also introduced.

Angiopoietin-like proteins are a family of proteins that are closely related to lipid, glucose and energy metabolism, as well as angiogenesis. To date, eight Angptls have been discovered, namely Angptl1 to Angptl8 that play key roles in metabolic regulation and marker assisted selection. In this review, we summarized current progress on the structure, signaling pathways, upstream regulatory genes and metabolic network of Angptl1-8. Finally, in combination with our work, the status and problems of animal breeding as well as the future prospects for Angptls were discussed.

OBJECTIVE: To investigate the application of autogenous cartilage transplantation in rhinoplasty. METHOD: We chose three kinds of treatment according to the shape of nasal tip and thickness of local soft tissue. Autogenous auricular cartilage transplantation combined with "L" type artificial prosthesis rhinoplasty was executed in 57 cases. Nasal alar cartilage transplantation combined with "L" type artificial prosthesis rhinoplasty was executed in 33 cases and septal cartilage transplantation combined with "willow leaf" type artificial prosthesis rhinoplasty was executed in 29 cases. RESULT: Improved nasal aesthetic effects were observed after operation in all of 119 cases, 64 cases were follow-up visited for 3 to 12 months. Both surgeons and patients were satisfied with the nasal shape. CONCLUSION Autogenous cartilage transplantation combining with artificial prosthesis rhinoplasty could effectively rebuild the nasorostral shape. We chose different kinds of cartilage according to the nasorostral condition. We can ensure that the whole nasal shape according to aesthetic requirement.

Medical science is a practical subject.It is the basic characteristic of the medical education to combine the theoretical knowledge with practice,therefore to emphasize and construct and bring into effect effectively the experimental and practical teaching system is very important and significant for the cultivation of medical professionals.

Abstract: Objective　In order to understand the radon exposure level of homes in Chongqing, this survey was carried out on the indoor radon concentration in 38 districts and counties of Chongqing. Methods　According to the population ratio of every 100 000 people, one monitoring site was arranged, and the number of parallel samples was 10% of the distribution sites. The monitoring sites covered 38 districts and counties in Chongqing. A total of 1 019 residential monitoring sites in 38 districts and counties in Chongqing were measured with radon accumulation detectors from July 2020 to June 2021. Results　The five districts/counties in Chongqing having the highest average concentration of residential radon in the year were Xiushan County 78.8 Bq/m3, Qianjiang District 78.0 Bq/m3, Yubei District 73.9 Bq/m3, Youyang County 71.4 Bq/m3 and Shapingba District 69.8 Bq/m3. The five districts/counties with the lowest mean concentration of indoor radon were 37.6 Bq/m3 in Zhongxian County, 36.4 Bq/m3 in Changshou District, 33.7 Bq/m3 in Kaizhou District, 33.2 Bq/m3 in Liangping District and 27.3 Bq/m3 in Wushan County. The concentration levels of radon in four seasons were 46.0 Bq/m3, 53.4 Bq/m3, 45.1 Bq/m3 and 59.5 Bq/m3, respectively. The concentration of radon was higher in Summer and Winter, and lower in Spring and Autumn, and the difference of concentration among four seasons was statistically significant (P<0.001). The radon concentration of newly built buildings after 2017 was relatively high, up to 61.8 Bq /m3, but there was no statistical significance in radon concentration in different building ages (P>0.05). The concentration of radon in rooms of buildings with less than 10 floors was higher, up to 63.2 Bq /m3, and there were significant differences in radon concentration among rooms of different floors (P<0.05). The average annual radon concentration in houses in Chongqing was about (51.6±19.5) Bq/m3, and the average annual effective dose of inhaling radon and its progeny by house-related people was about (1.38±0.52) mSv. Conclusion　The average annual radon concentration level of houses in Chongqing is within the standard limit value recommended by China, but the prevention and control of radon should be strengthened.

Objective To investigate the preventive effect of oral ulcer using two methods in radio-therapeutic patients after tongue squamous cell carcinoma operation. Methods Thirty-six radiotherapeutic patients after tongue squamous cell carcinoma operation were collected from May 2012 to May 2014 and divided into control group and treatment group according to the random number table method. Regular oral nursing was administered to control group, treatment group were received regular therapy plus orally vitamin B and cetylpyridinium chloride gargle for gargling, and then evaluated the efficacy according related standards. Results Less oral ulcer (1/18 vs.7/18,χ2=-2.372,P<0.05), better oral lustration (Z=-2.093,P<0.05) and overall oral nursing effect (Z=-2.166,P<0.05) were observed in treatment group compared to control group after 7 days of therapy, however, treatment group presented no significantly better comfort level at the same time (Z=-1.708,P>0.05). Conclusions Regular therapy plus orally vitamin B and cetylpyridinium chloride gargle for gargling are effective for the prevention of oral ulcer in radiotherapeutic patients after tongue squamous cell carcinoma operation.
