Objective:To study the clinical manifestations and prognosis of patients with liver perivascular epithelioid cell tumor (PEComa).Methods:The clinical manifestations, imaging findings, pathological features, treatment and prognosis of 17 patients with liver PEComa managed in Shenzhen People's Hospital from September 2002 to January 2020 were retrospectively analysed.Results:The patient age of onset of liver PEComa was 22 to 54 years (average 34.8 years). There were 13 females and 4 males. 82%(14/17) of patients presented with no significant symptoms. 15/17 had solitary tumors. The diagnostic rate using preoperative B-ultrasound, CT and MRI was low. Postoperative pathological studies showed the tumor cells were mainly epithelioid cells with hyaline or eosinophilic cytoplasm. There were abundant blood vessels in the tumor tissues. Adipose tissues were also seen. Immunohistochemistry showed both HMB45 and Melan-A positivities to arrive at the diagnosis. All patients were treated with surgical resection. There were no recurrence, metastasis, or death on follow-up.Conclusion:Hepatic PEComa occurred more frequently in young women and it had no specific clinical manifestations. Except for a small number of tumors with adipose tissue detected on preoperative imagings, this tumor was difficult to diagnose, or even be suspected on preoperative imagings. Pathological examination combined with immunohistochemistry after surgery established the diagnosis. Surgery resulted in good prognosis.

To obtain oleaginous yeast mutants with improved lipid production and growth rates, an atmospheric and room temperature plasma (ARTP) jet was used with a 96-well plate for high throughput screening. Mutants with changes in growth rates and lipid contents were obtained. At a lethality rate of 99%, the positive mutation rate of the yeast cells was 27.2% evaluated by the growth rates of the mutants and the comparison with the wild strain. The fermentation in a medium composed of yeast extract (10 g/L), peptone (10 g/L) and D-glucose (20 g/L) resulted in the lipid yield of the mutant (C4) with 4.07% (W/W) compared with that of the wild strain (1.87%).

Objective To investigate the effect of cyclosporine blood level at first year after kidney transplantation on patients with a survival time over 10 years. Methods 380 patients with functional allograft, a survival time over 10 years and long-term administration of cyclosporine A (CsA) were studied, and received CsA-based treatments. According to the blood CsA level at the first year after kidney transplantation, patients were divided into five groups: group 1, blood CsA level was above 0. 208 μmol/L (1 μmol/L = 1201.9 μg/L), group 2, blood CsA level between 0. 166-0. 208μmol/L; group 3, blood CsA blood level between 0. 125-0. 166 μmol/L; group 4, blood CsA blood level between 0. 083-0. 125 μmol/L; group 5, blood CsA level less than 0. 083 μmol/L. Systolic blood pressure (SBP), diastolic blood pressure (DBP), serum creatinine(SCr), uric acid (UA), cholesterol (CH), triglyceride (TG), alanine aminotransferase (ALT), direct bilirubin (DBil) and total bilibubin (TBil), albumin (Alb), hemoglobin (Hb), count of white blood cells and positive rate of proteinuria in 5 groups at the 1st, 5th and 10th year after kidney transplantation were analyzed. Results At the 5th year SBP in groups 1 and 2 was higher than in groups 3, 4 and 5. UA level in group 5 was lower than other groups, and Alb level in group 5 was higher than other 4 groups. Proteinuria positive rate in groups 4 and group was lower than other groups. At the 10th year after kidney transplantation,indexes among 5 groups had no statistically significant difference, except for SBP, DBP, DBil and CH in some groups. There was also no significant difference in SCr level among 5 groups at the 5th or 10th year after transplantation. Conclusion Blood CsA levels at the first year after kidney transplantation has no significant effect on long-term allograft function. But higher level of CsA (＞0. 166μmol/L) at the first year maybe predict high rate of hypertension, high blood UA and proteinuria at the 5th and 10th year after transplantation.
