Chinese Journal of Information on Traditional Chinese Medicine 2006;0(02):-
Objective Serum pharmacological assessment:the effect of Rubia yunnanensis extract on the immune function stimulated by superantigens of streptococcus. 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.
2.Individual dose monitoring and registry for radiation workers in China
Chinese Journal of Radiological Medicine and Protection 2021;41(2):81-84
Individual dose monitoring and registry for radiation workers plays a significant role in ionizing radiation protection and occupational health management. Since the nationwide implementation of monitoring from the 1980s, individual dose monitoring for radiation workers in China has been going on nearly 30 years, which is of significance in radiation protection optimization, and occupational health and protection for radiation workers. In order to improve individual dose monitoring and registry, to prevent and control occupational radiation diseases, and to help build "Healthy China" program, this paper presents the evolution of individual dose monitoring and registry in China, discusses the key points and difficulties faced, and proposes suggestions.
3.Mitochondrial combined oxidative phosphorylation deficiency type 1 in childrena case report and literature review
China Tropical Medicine 2023;23(2):200-
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.

International Journal of Surgery 2008;35(7):465-467
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.

8.Sequential changes of HIF-1αprotein and mRNA in hypoxic bovine retinal microvessel endothelial cells
International Eye Science 2005;5(2):225-228
● AIM: To investigate the sequential changes of HIF-1 α Protein and mRNA in hypoxic bovine retinal microvessel endothelial cells.● METHODS: The bovine retinal microvessel endothelial cells were cultured in normoxic and CoCl2-induced hypoxic conditions respectively. Expressions of HIF-1 α Protein were measured with immunohistochemical staining, and RT-PCR was used to determine the HIF-1 α mRNA.● RESULTS: HIF-1 α began to increase 1h after hypoxia,and reached the peak at 4h. After 16h, it declined significantly. Compared with the normoxic group, the expression of HIF-1 α protein in the hypoxic groups had significant difference (P<0.01), and HIF-1 α mRNA expression was unchanged under hypoxia.● CONCLUSION: HIF-1 α participates in the hypoxic procedures in retinal microvessel endothelial cells, and hypoxia induce time-dependent changes of HIF-1 α protein expression, which is not modulated on the transcription level. Analysis of HIF-1 α expression revealed a temporal and spatial changes with regard to the hyperoxic repression, indicating that HIF-1 may play a major role in the development of retinopathy of prematurity and other ischemic retinal disorders such as diabetic retinopathy.

BACKGROUND:Adipose-derived stem cel s have different sources, but it is unclear whether these cel s from different sources have difference in their biological properties.
OBJECTIVE:To detect the in vitro proliferation and chondrogenic differentiation of adipose-derived stem cel s derived from renal fat capsule and groin.
METHODS:Adipose-derived stem cel s from renal fat capsule and groin of rats were isolated, cultured and identified. MTT assay was used to detect in vitro proliferation ability of these cel s. Passage 3 cel s were under chondrogenic induction for 2 weeks. After induction, the expression of type II col agen was observed by immunofluorescence detection, and RT-PCR was employed to detect the expression levels of Aggrecan and type II col agen mRNA in the two groups.
RESULTS AND CONCLUSION:After primary culture and passage, adipose-derived stem cel s from the renal fat capsule and groin of rats exhibited similar morphology, and over 95%of cel s expressed CD44 in the two groups. Adipose-derived stem cel s from two sources showed an S-shaped growth curve in vitro and were positive for type II col agen. After RT-PCR detection, the expression levels of Aggrecan and type II col agen mRNA had no difference in adipose-derived stem cel s from renal fat capsule and groin (P>0.05). Experimental results show that adipose-derived stem cel s from both renal fat capsule and groin exhibit stable growth, rapid proliferation and chondrogenic differentiation under orient induction in vitro, indicating there is no difference between these cel s from two sources.
