Objective To analyse the clinical characteristics of the patients with intracranial germinoma.Methods Medical records of 45 patients with intracranial germinoma between 1993 and 2005 were retrospectively reviewed.Results The study population consisted of 30 males and 15 females,ranging in age from 20 months to 56 years old.Nineteen patients' tumors(42.2%)were in sellar region,13(28.9%)in pine region.Twenty-four patients(53%)had headache,nausea and vomiting.Twenty patients(40%)had blurred vision and visual field damage.Seventeen patients(38%)had diabetes insipidus.Twelve patients(27%)had hypopituitarism.Image study showed lesions were high density in CT and long T1,T2 in MRI.The signal was enhanced equally by contrast medium.?-hCG level of serum and CSF was measured,4 of 6 patients' serum ?-hCG level was elevated.Among those 4,?-hCG level in 2 patients' CSF was increased.Twelve patients were diagnosed pathologically,and 11 patients were diagnosed with experimental radiation.Others were diagnosed by clinical manifestation and image study.Eleven patients accepted operation therapy.Most of patients were treated with radiotherapy and chemotherapy.Symptoms were relieved obviously.Conclusion Intracranial germinoma mainly affects male children and adolescents.Common location of lesions is suprasellar and pine.Main manifestations of intracranial germinoma are headache,nausea,vomiting,blurred vision,visual field damage and diabetes insipidus.Biochemical and image examination have significance to diagnosis.Radiotherapy is a common and effective treatment for intracranial germinoma.

Objective To research the expression and clinical significance of SALL 4 gene in cervical cancer .Methods The ex-pression of SALL4 in 56 samples of cervical cancer and 35 samples of normal cervical tissues was detected by immunohistochemistry and RT-PCR ,and its relationship with the clinicopathological characteristics of cervical cancer was analyzed .Results The expres-sion of SALL4 mRNA was 2 .56 ± 0 .22 in cervical cancer tissues ,which was significantly higher than 0 .38 ± 0 .03 in the normal cer-vical tissues .the difference between them had statistical significance(t=58 .1 ,P<0 .01);the positive expression rate of SALL4 pro-tein was 80 .4% (45/56) in cervical cancer ,which was significantly higher than 11 .4% (4/35) in the normal cervical tissues (χ2 =41 .177 ,P<0 .01) .The positive expression of SALL4 in the cervical cancer tissues was correlated with the differentiation status of tumor ,which in the middle and high differentiation groups was lower than that in the low differentiation group (χ2 =4 .226 ,P=0 .039) ,but had no correlation with age ,International Federation of Gynecology and Obstetrics (FIGO) stage ,tumor size ,pathologi-cal type and lymph node metastasis(P>0 .05) .Conclusion SALL4 is highly expressed in the cervical cancer tissues and correlated with the tumor differentiation ,which might play an important role in the occurrence and development of cervical cancer .

Objective To study effect of bufalin on invasion and metastasis of gastric cancer cells and related mechanism.Methods AGS human gastric cancer cell line was used for in vitro experiments.Cultured cells were treated by negative control group,bufalin group and oxaliplatin group.Cell proliferation was determined by MTT.Invasion and metastasis were observed by Wound-Healing Assay and Transwell Assay.Expression levels of E-cadherin,matrix metalloproteinases (MMP)-2,MMP-9 were detected by Western blotting.Results Bufalin was found to significantly inhibit the proliferation of AGS cells in a dose and time dependent manner.Wound-Healing Assay and Transwell Assay showed that as compared with the blank control group,bufalin inhibited invasion and metastasis of AGS cells (P＜ 0.05),but there was no statistically significant difference between bufalin group and oxaliplatin group (P＞0.05).Western blotting showed the expression of E-cadherin was increased in bufalin group as compared with the blank control group while the expression levels of MMP-9 and MMP-2 were down-regulated (P＜0.05),but there was no statistically significant difference between bufalin group and oxaliplatin group (P＞ 0.05).Conclusion Bufalin has anti-cancer activity on gastric cancer cells,and it has the ability of inhibiting cancer cell invasion and metastasis,and regulating the expression of some related gene.

Objective: To explore drug resistance of different viral loads, and investigate the relationship between drug resistance and CD4⁺T cell counts in patients with HIV antiretroviral therapy (ART) in China from 2003 to 2015. Methods: Data were extracted from the Chinese National HIVDR Surveillance database from 2003 to 2015. For this study, the data collected were as follows: having received ART for ≥12 months; 18 years or older; demographic characteristics, information of ART, CD4⁺T cell counts, viral load (VL) and HIV drug resistance of a total of 8 362 patients were collected. Multi-variables non-conditional logistic regression model was used to study the relationship between viral load, HIV drug resistance and CD4⁺T cell counts. Results: Participants with age of (41.8±10.5) years were enrolled in this study. Among them, 59.9% (5 009 cases) were men. The percentage of CD4⁺T cell counts <200 cells/μl in the total population was 17.9% (1 496 cases), the highest was in VL ≥1 000 copies/ml with drug resistance, which was 43.0% (397/923) , followed by VL 50-999 copies/ml with drug resistance, which was 31.1% (69/222), and the lowest was in VL 50-999 copies/ml without drug resistance 13.2% (273/2 068). Compared to VL 50-999 copies/ml without drug resistance, VL<50 copies/ml, VL 50-999 with drug resistance, VL≥1 000 copies/ml without drug resistance, and VL ≥1 000 copies/ml with drug resistance, the OR (95%CI) of CD4 <200 cells/μl were 0.9 (0.7-1.0), 3.2 (2.3-4.4), 2.6 (2.1-3.2), and 4.9 (4.0-5.9), respectively. Among 222 patients with VL 50-999 and HIVDR, the most frequent antiretroviral drugs were EFV and NVP, both of which were NNRTI, and whose percentage both were 94.1% (209 cases). The most frequent mutations were M184V/I (NNRTI), and the percentage was 26.1% (58 cases). The second one was K103N (NNRTI), and the percentage was 22.5% (50 cases). The percentage of V32L/E (PI) and V82A (PI) were lower, they were 0.9% (2 cases) and 0.5% (1 case) respectively. Conclusion Decreased CD4⁺T cell counts were associated with HIV drug resistance at low viraemia. In the case of low viral load, the most vulnerable were the NNRTI antiviral drugs such as EFV and NVP.

Human platelet lysates(HPL), as a new type of biomaterial, can promote tissue repair, cell proliferation and inflammation control. This paper introduced the development of HPL in the field of regenerative medicine and cell therapy and summarizes their application. The potential of HPL to promote cell proliferation was used as an entry point to show its advantages as a supplement of cell culture medium. Since there is currently no standard procedure for HPL preparation, this paper sorts out the standardization elements such as raw materials source, donor variability and preparation technology, in order to provide reference for the establishment of standards of relevant industry in the future.

Objective Bibliometric approaches are used to investigate the characteristics and benefits of traditional Chinese medicine treatments for dominant diseases that can be applied in clinical therapy to effectively manage geriatric diseases.Methods Clinical research literature on the use of traditional Chinese medicine in the treatment of geriatric diseases within the past 10 years was retrieved from CNKI,Wanfang,VIP,and CBM databases.The research trends and clinical efficiency of each disease were statistically analyzed to determine the dominant diseases of TCM.Results A total of 22 859 articles were collected,with 3768 included in the research.In accordance with the International Statistical Classification of Diseases and Related Health Problems(ICD-11)of the World Health Organization,the diseases were classified into 17 categories and 149 diseases.The diseases primarily affect the circulatory system,skeletal musculoskeletal or connective tissue system,and digestive system.Conclusions Traditional Chinese medicine clinical trials on the treatment of geriatric illnesses cover a diverse spectrum of diseases,although the distribution of focus is unequal.Potential dominant illnesses were eventually identified to include osteoporosis,constipation,and hypertension,with heart failure,stroke,coronary heart disease,diabetes and its complications,and insomnia being potential sub-dominant diseases.
