Methods Using cell culture technique, mouse spleen lymphocytes and peritoneal macrophages were culture with superantigens of streptococcus and serum of Rubia yunnanensis. Lymphocytes proliferation stimulated by superantigens of streptococcus measured by MTT assay. NO level in mouse peritoneal macrophages affected by Rubia yunnanensis at different concentrations were determined and compared. Results Serum of Rubia yunnanensis significantly inhibit the proliferation of lymphocytes stimulated by superantigens of streptococcus, compared with normal control. NO content of macrophages culture in Rubia yunnanensis extract group were lower than those of control. In these tests, the effect of the extract by alcohol is more obvious than that of extract by water. Conclusions Rubia yunnanensis extract has effect in inhibiting immune function and anti-infect activity, it could be applied in clinical practice for immunoregulation and treatment of psoriasis.

Objective　To summarize the phenotypic and genotypic characteristics of mitochondrial combined oxidative phosphorylation deficiency type 1 (COXPD1), and to improve the clinicians' awareness of this mitochondrial encephalomyopathy. Methods　The clinical characteristics, physical examination, laboratory examination and other data of a child with COXPD1 were analyzed retrospectively. The diagnosis was confirmed by clinical whole exon sequencing and high-precision mitochondrial genome full-length PLUS gene detection, and the phenotype and genotype were analyzed by reviewing relevant literature. Results　A one-year and five-month-old boy mainly presented with hyperlactacidemia and abnormal liver function. Clinical whole exon sequencing showed that the child had homozygous variation of c. 688G>A(p.G230S) in the GFM1 gene. Sanger sequencing verified that the variation was respectively inherited from the parents of the child (both were heterozygous) with the autosomal recessive inheritance pattern. The high-precision mitochondrial genome full-length PLUS detection also did not find pathogenic mutations related to clinical phenotypes. The child was diagnosed with COXPD1. After "cocktail" therapy and liver protection therapy, the patient's condition improved. Conclusions　The phenotype of COXPD1 is complicated and variable, mainly liver type and brain type. The mutation of GFM1 gene affects mitochondrial translation system function, and early gene detection is helpful for definite diagnosis.

Lysimachiae Herba and Desmodii Styracifolii Herba are common traditional Chinese medicines for treating lithiasis. Both of them have efficacies of clearing heat, diuresis and eliminating calculi. However, there are some differences in their clinic applications. The former is mainly used to treat hepatolithiasis, gallstones, jaundice, stranguria and gout; Whereas the latter is mainly used to treat urinary calculus. In this paper, the pharmacological effects of Lysimachiae Herba and Desmodii Styracifolii Herba on removing calculus, choleresis, anti-inflammation and oxidation resistance were compared and analyzed based on document retrieval. In conclusion, both of them show the preventive and therapeutic effects on kidney stones and gallstones. Particularly, Desmodii Styracifolii Herba has a better effect in treating the kidney stones, while Lysimachiae Herba has a better effect in treating cholesterol gallstones.

Objective To investigate the clinical effects of surgery treatment of the Tibia plateau fracture.Methods Thirty-two cases diagnosed Tibial plateau fracture were performed internal fixation and bone grafting surgery treatment.Results According to Rasmussen Evaluation,there were the gifted 22 cases(68.8%)excellent,6 cases(18.8%)good,2 cases(6.3%)ordinary,2 cases(6.3%)poor.The good rate Was 87.6%.Conclusions Surgery is effective to trot Tibial plateau fracture.A stable internal fixation,as far as possible,reduces the blood supply to fracture block interference and protects joint subsidiary structure to correct joint function rehabilitation treatment.

Objective:To observe the effects of a preparation of chinese traditional medicine Zengshengping (ZSP) in the treatment of oral lichen planus (OLP).Methods:200 patients with OLP were randomly divided into 2 groups with 100 in each.The patients in one group were treated with ZSP and those in another with levomisolum.The patients were followed up for two years.Results:The total effective rate in ZSP or levomisolum treated group were 90% and 62% respectively (P<0.025).Conclusion:ZSP is more effective in the treatment of OLP than levomisolum.

Objective To study a new method of correcting flaring ear. Methods Auricular cartilage was slited from posterior auricula. On Gibson's principle of cartilage distortion antero-lateral cartilage membrane was scarified in order of the involute interpolation of anthelix and cartilage membrance was ground. Then the cartilage outside the slited line was put behind the cartilage inside the slited line. Finally,cartilage was operated with Mustarde's mattres suture. Results 12 patients with flaring ear ( 14 ears) were corrected with this operating method and appearance of corrected ears were very good after operation. Following up for 6-18 months, no one recurred. Conclusion Otoplasty of slited cartilage is an effective method of correcting flaring ear.

Objective To investigate the effect of IGF-1 on the TGF-β3 induced chondrogenesis of MSCs encapsulated in alginate beads and its application in cartilage tissue engineering.Methods MSC chondrogenesis in alginate beads was induced by TGF-β3 and/or IGF-1.Collagen type Ⅱ,aggrecan and Sox-9 expression was evaluated by immunostaining,RT-PCR and Western blot,respectively.Scanning electron microscope and laser confocal microscope were used to observe the differentiated chondrocytes when cultured on the chitosan-based scaffold.Results TGF-β3 with IGF-1 induced MSCs in alginate beads to express the higher level of collagen type Ⅱ,aggrecan and Sox-9 than any other growth factor alone (P＜0.05).The correlation coefficient between Sox9 and collagen type Ⅱ or aggrecan was 0.95 and 0.91,respectively.The chitosan-based scaffold supported the cell's adhesion,migration and proliferation.Conlusion IGF-1 enhances the TGF-β3-induced MSC chondrogenesis via upregulating Sox9 expression.The chitosan-based scaffold is biocompatible with the differentiated chondrocytes.

Cancer cells can secrete programmed death ligand 1 (PD-L1) to bind with inhibitory regulatory protein of programmed death 1 (PD-1) which lies on T-cell lymphocyte.Consequently,the activity of the T cells reduces,and the apoptosis cells increase.It's one of the pathways of newly discovered tumor immune escape.Primary hepatic cancer is one of the common malignant tumors of digestive system and closely related to viral hepatitis B in China.PD-1/PD-L1 pathway plays an important role in tumorigenesis and development of primary liver cancer.In this paper,the research updates of PD-1/PD-L1 in primary hepatic carcinoma were summarized.
