Objective To investigate the expression of CKLF-like MARVEL transmembrane (CMTM)domain-containing family in clear cell renal cell carcinoma(ccRCC)and its significance.Methods Seventy-five samples of ccRCC were collected,including 50 males and 25 females,mean age (59 ± 10)years.There were 34 cases in clinical stage Ⅰ,23 cases in stage Ⅱ,14 cases in stage Ⅲ and 4 cases in stage Ⅳ.The pathological differentiation was 3 cases of grade Ⅰ,1 case of grade Ⅰ-Ⅱ,35 cases of grade Ⅱ,10 cases of grade Ⅱ-Ⅲ,18 cases of grade Ⅲ,3 cases of grade Ⅲ-Ⅳ and 5 cases of grade Ⅳ.The expression of CMTM3 and CMTM5 proteins in 75 cases of ccRCC and corresponding adjacent normal kidney tissues was detected by tissue microarray and immunohistochemistry.Results The positive expression rate of CMTM3 and CMTM5 was 98.7％,97.3％ in the adjacent normal kidney tissues,and 44.0％,68.0％ in ccRCC tissues(P ＜ 0.05).The expression of CMTM3 and CMTM5 had no correlation with the gender,age,clinical staging and pathological differentiation(P ＞ 0.05).Conclusion CMTM3 and CMTM5 could be ccRCC suppressor genes,and their mutation or methylation might be an early event in the carcinogenesis of ccRCC,thus promise them to be potential biomarkers in early diagnosis.

Objective This article reported the treatment process and pharmaceutical monitoring points of a 73 year old patient with latent tuberculosis and positive hepatitis B core antibody,whose focal segmental glomerulosclerosis(FSGS)was trea-ted with cyclosporine and rituximab instead of glucocorticoids because of gastrointestinal ulcer.Methods Clinical pharmacist participated in the treatment process of immunosuppressive therapy,infection prevention,and complications management of ne-phrotic syndrome,and then conducted pharmaceutical monitoring.Results The patient's nephrotic syndrome was relieved,and the urine protein decreased from around 8 g to below 1 g,indicating good disease control.Conclusion The combination of rituximab and cyclosporine could achieve in partial or nearly complete relief of nephrotic syndrome.For patients with latent tuber-culosis and hepatitis B core antibody positive,attention should be paid to the prevention of infection when using immunosuppres-sants such as monoclonal antibody.As patients with nephrotic syndrome were treated with multiple medications,drug interactions and concentrations monitoring should be focused on when using cyclosporine,as well as regular follow-up of patients and guarding against adverse reactions including renal dysfunction and infection.The participation of clinical pharmacists in the clinical therapy was of great significance,which ensured the effectiveness of disease treatment and medication safety.
