Objective To study the anti-tumor effects of pEgr-1-endostatin-TNF-α generadiotherapy on mice bearing Lewis lung carcinoma, and to explore the mechanism involved. Methods 240 mice with Lewis lung carcinoma were randomly divided into four groups, including control group,irradiation group, liposome group, and liposome combined irradiation group. The plasmids packed by liposome were injected locally into the tumors of the mice, and the tumors of liposome combined irradiation group were irradiated with 10 Gy γ-rays 24 h later. The expression levels of TNF-α and endostatin in mouse serum were measured by ELISA. Then the tumor growth rates at different time were observed. Tumor angiogenesis density were estimated on frozen sections stained with CD31 by using the Chalkley counting method to vessel hot-spots. The tumor inhibition rates were also calculated. Results Radiation induced the expression of pEgr-1-endostatin-TNFα. The endostatin and TNF-α were expressed steadily for about 4 weeks. The highest levels of expression of the endostatin and TNF-α were (52. 64 ±4. 19)and( 12. 01 ±0. 87 ) ng/ml at 2 week. The expression levels of TNF-α and endostatin were higher in combined therapy group than those in other groups( F = 29. 726,P ＜ 0.05 ). Compared with the control group, the density of tumor angiogenesis were depressed [ (4.7 ± 0. 8 ) vs ( 10.0 ± 1. 2)/field, t = 14. 063, P ＜ 0.05 ] and tumor growth were significantly inhibited compared to the control group and irradiation group [ (5907. 2 ±78.6), (4653.4±32.8) and (763.5 ± 12.3) mm3, F= 16.415,P ＜0.05)]. Conclusions The expression of pEgr-1-endostatin-TNFα could be induced by irradiation in dose- and time-dependent manner. The effect of antitumor and angiogenesis inhibition may be more significant than irradition.

Qigui Tongfeng tablet (QLTFT) is a traditional Chinese medicine with good effect for treating gout. Here, network pharmacology method and molecular similarity analysis were utilized to study the effective substance basis and molecular mechanism of the QLTFT on the gout. The similarity to the medicinal compounds is reflected in the Tanimoto coefficient that gives the structural similarity of two compounds. Operationally, similar modifiers were described as pairs of concepts with a similarity score of 0. 500. The results of the molecular similarity analysis suggested that the flavonoids in QLTFT could be new leads for gout. Furthermore, complex biological systems may be represented and analyzed as computable networks. Two important properties of a network were degree and betweenness. Nodes with high degree or high betweenness may play important roles in the overall composition of a network. And the results of network analysis showed that dongbeinine, verticinone-N-oxide, verticine N-oxide, peimine, peiminine, isobaimonidine, dongbeirine, peimisine and simi-arenol which with high degree acted on xanthine dehydrogenase/oxidase, matrix metalloproteinase-9, an arachidonate 5-lipoxygenase-activating protein, tyrosine-protein kinase and etc. Inhibition of these targets can prevent the formation of uric acid, reduce inflammation by uric acid and regulate the body's immune response. Thus, these compounds may be the main effective substance basis. The research results not only reveals its molecular mechanism, but also provide a theoretical basis for the quality control of drugs and clinical application.

Objective:To observe the application of near-infrared autofluorescence imaging (NIRAF) technology combined with carbon nanoparticle (CNP) negative imaging in identification of parathyroid gland (PG) during thyroid carcinoma surgery.Methods:80 patients with thyroid cancer who underwent total thyroidectomy + central lymph node dissection performed by the same experienced physician team at the 960th Hospital of the PLA from Jan. to Mar. 2022 were prospectively included. Before operation, they were divided into two groups using random number table method before surgery: control group (40 cases) using CNP negative imaging, and experimental group (40 cases) using CNP negative imaging combined with NIRAF technique for intraoperative identification of PG. The gold standard for the identification of parathyroid glands was to compare the amount of intraoperative discovery retention misresection and transplantation of PG and the number of postoperative parathyroid hormone (PTH) and the number of complications in the two groups by immune colloidal gold technique. SPSS 25.0 software was used for statistical analysis.Results:All patients in the two groups were successfully operated and followed up. 137 149 PG were found and confirmed in the control group and the observation group, 108 132 PG were retained in situ and 29 17 PG were transplanted, the differences were statistically significant (all P <0.05) ; The number of A1 PG was 103 and 109, respectively. Among them, 84 102 were retained in situ and 19 7 were transplanted, the difference was statistically significant ( P <0.05) . There was no significant difference in the amount of A2 type PG and B type PG between the two groups ( P >0.05) . No A3 type PG was found in the two groups, and a total of 3 A3 types of PG were confirmed in postoperative pathological reports. There were no significant differences in misresection in the control group and the observation group, 5 and 2 PG were mistakenly cut, respectively (all P >0.05) . The PTH 1 day after surgery was 17.7 (5.6,30.4) pg/mL in the control group and 21.7 (12.8,38.3) pg/mL in the observation group, the difference was statistically significant ( P<0.05) . There were no significant differences in the levels of serum calcium and serum phosphorus 1 day after operation and PTH 1 month after surgery between the two groups (all P > 0.05) . Conclusion:Compared with CNP alone, combined with NIRAF technique can quickly and effectively identify PG, and PG can be better protected in situ and postoperative hypoparathyroidism can be reduced.

The borneol was included with β-CD and prepared Fufang Danshen intestinal adhesion pellets. GC method for determination of borneol in Fufang Danshen intestinal adhesion pellets was established to study its in vitro dissolution and make a comparison with the Fufang Danshen tablet, in this way, the rationality of dosage form was evaluated. The first method of dissolution determination was used for determining the in vitro dissolution of borneol in Fufang Danshen intestinal adhesion pellets in artificial intestinal juice, and Fufang Danshen tablet in artificial gastric juice and intestinal juice, respectively. Result shows: the concentration of borneol in Fufang Danshen intestinal adhesion pellets and Fufang Danshen tablet was 0.79% and 0.80%, respectively. Its in vitro dissolution was nearly 70% within 12 h in Fufang Danshen intestinal adhesion pellets, and in Fufang Danshen tablet, the dissolution was about 60% within 20 min and more than 90% within 40 min, and in artificial gastric juice, was less than 20% within 40 min but more than 80% till 150 min. Research suggests that in comparison with Fufang Danshen tablet, in vitro dissolution of borneol in the Fufang Danshen intestinal adhesion pellets showed an obvious sustained release behavior. The borneol in Fufang Danshen intestinal adhesion pellets was included with β-CD and prepared enteric preparations. To some extent, the stimulation on stomach and intestinal mucosa can be reduced and safety can be improved.

OBJECTIVETo explore an ideal method for repairing the skin-soft tissue defects according to the different anatomical units of cheek, and find reasonable design principles to transfer the expanded flaps.

METHODSAccording to the location of the defect, we placed 1-3 appropriate expanders nearby, when the flap expanded enough we adopted advanced skin flaps, rotation-advanced skin flaps or transposition skin flaps to repair the defect. In this group of 269 cases, the defects were secondary to hemangioma, various scars, nevus or nevus excision.

RESULTSIn all 269 cheek defects, 305 expanded flaps were developed which included 145 rotation-advanced flaps, 121 advanced skin flaps and 39 transposition skin flaps. 52 of them generated complications, including blood circulation disorder of the distal part of flaps, hematoma, infection, injection, lower eyelid ectropion, expander extrusion and capsule contracture. Mostly, these complications didn't affect the final results.

CONCLUSIONSThe principles presented in this article are the guidelines to treat the skin-soft tissue defect of check with tissue expansion. The satisfied results come from the reasonable flap designs.

Tertiary hyperparathyroidism is commonly observed in patients with long-standing chronic kidney disease (CKD) after renal transplantation and is characterized by the autonomous hypersecretion of PTH leading to hypercalcemia.The primary treatment is surgery.After the introduction of cinacalcet,both surgical and medical methods have been commonly performed to treat tertiary hyperparathyroidism.However,which treatment is more appropriate has not been fully demonstrated.In this paper,the author will systematically review the related research of surgical treatment and cinacalcet in the treatment of 3HPT,and summarize their respective therapeutic effects.

OBJECTIVETo evaluate the applicability of the polymorphic marker closely linked with beta-globin gene for the preimplantation genetic diagnosis (PGD) in couples at risk of having child with beta-thalassemia.

METHODSSingle cell multiplex nested PCR which coamplifies the beta-globin gene and the closely linked polymorphic marker, HumTHO1 gene, was applied in six clinical PGD cycles for four couples with beta-thalassemia.

RESULTSIn six clinical PGD cycles, a total of 44 embryos were biopsied and 44 blastomeres were obtained. Forty-one blastomeres were amplified and thirty-five embryos were given definite diagnoses. Fourteen embryos were transferred back to the uterus of the patients and one pregnancy went on well and ended with one live healthy birth, which confirmed the results of PGD. The average amplification efficiency of single blastomere was 89.7% and the average allele drop-out(ADO) rate was 14.4%. The coamplification of HumTHO1 could help to detect the existence of ADO and contamination.

CONCLUSIONThis is the first report on unaffected pregnancy resulting from PGD using multiplex nested PCR in China. The simultaneous amplification of polymorphic marker closely linked to beta-globin gene(HumTHO1) could help to resist the risk of misdiagnosis in PGD caused by ADO and contamination.

OBJECTIVETo evaluate the effect of autologous bone marrow-derived stem cell (BMSCs) transplantation in the treatment of liver failure and decompensated hepatic cirrhosis.

METHODSBone marrow was harvested (65-95 ml) from 24 patients in the transplantation group. The BMSCs were isolated and infused into liver or spleen of patients via hepatic or splenic artery. At different time points after the transplantation, the patients' liver function and prothrombin time (PT) were evaluated, and the survival rate and symptoms of the patients were recorded.

RESULTSAll the serum biochemical indexes remained stable 2 weeks after the transplantation, and at 4 weeks after transplantation, albumin level increased significantly in comparison with the preoperative level (P<0.05). At 12 weeks, the albumin level further increased (P<0.01) along with Pre-ALB (P<0.01), while total bilirubin, tolal bile acid, PT and fibrinogen were all significantly lowered (P<0.05), and globulin, ALT, and AST remained unchanged (P>0.05). One week after the transplantation, improved appetite was observed in 22 cases (91.67%), and 21 cases (87.5%) showed better physical strength; at 2 weeks, hepatic face improved in 15 cases (62.5%), and spider telangiectasia was significantly reduced in one case; at 12 weeks, the survival rate of the patients was 62.5%, and 9 died or gave up treatment due to chronic liver failure complicated by spontaneous bacterial peritonitis, hepatorenal syndrome, or DIC. No complications associated with the transplantation occurred in these patients.

CONCLUSIONBMSC transplantation can significantly improve the liver function of patients with terminal liver disease with good safety and effectiveness.
