Objective:To summarize the experience of Bacillus Calmette-Guerin(BCG) in the treatment of bladder cancer secondary to renal transplantation.Methods:The clinical data of 5 patients who underwent BCG bladder irrigation after secondary bladder cancer after kidney transplantation in Tianjin First Central Hospital from January 2015 to December 2019 were analyzed. There were 1 male and 4 female cases. During the period of immunosuppression after transplantation, 1 case developed secondary high-level non-muscular invasive bladder cancer (NMIBC), 3 cases developed secondary low-grade NMIBC, and 1 case developed secondary glandular cystitis (4 cases). The mean age of the 5 patients with secondary bladder cancer was 59.7±4.0 years. Case one with high level NMIBC was treated with transurethral resection of bladder tumor (TURBT) and postoperative irrigation of epirubicin. Case 3 and 5 with low-level NMIBC accepted regular postoperative irrigation of gemcitabine. No irrigative therapy was performed in case 2. Bladder cancer recurred in case 1, 2, 3 and 5 after 20.1±9.7 months. TURBT was observed in all the 4 patients, among which 3 were of high grade NMIBC and 1 was of low grade NMIBC. Four patients were irrigated with BCG 2 weeks after operation. Postoperative pathology indicated low-level NMIBC in case 4, and BCG was irrigated 2 weeks after the operation. During perfusion therapy, immunosuppressive agents were continued.Results:During BCG perfusion, 4 of the 5 cases showed BCG related local inflammation, among which 2 cases presented symptoms of bladder irritation, 1 case presented hematuria, and 1 case presented hematuria with low fever. Patients with frequent urination, pain in urine, hematuria and other symptoms improved after drinking plenty of water, taking bed rest and taking levofloxacin (0.5g/ day ×7 days). Patients with low fever were treated with antipyretic treatment. No antituberculous agents were used prophylactically during BCG perfusion. There were no symptoms of tuberculosis infection or sepsis. The function of transplantated kidney was normal and no tendency of rejection. The 5 patients were followed up for 7-24 months, 1 patient was lost to follow-up after 7 months of BCG bladder perfusion, and no tumor recurrence or metastasis was found in 5 patients during the follow-up.Conclusions:The use of immunosuppressive agents does not reduce the biological activity of BCG, and BCG does not increase the risk of systemic toxicity or affect the function of transplanted kidneys in immunocompromised patients. BCG is a treatment option for bladder cancer secondary to renal transplantation.

Objective:To know the work status of clinical pharmacy in medical institutions of Guizhou province. Methods:Ques-tionnaires were used to analyze the situation of clinical pharmacy in 108 medical institutions of Guizhou province. Results: A total of 246 questionnaires were taken back, and among the 231 valid questionnaires were received including gradeⅡor above hospitals. The main contents of clinical pharmacy work carried out in medical institutions included 7 aspects: pharmacists ’ participation in ward rounds, which accounted for 47. 11%; pharmacists’ participation in case consultation, which accounted for 16. 65%; pharmacists’ participation in teaching practice, which accounted for 38. 84%; pharmacists’ participation in prescription evaluation and analysis, which accounted for 72. 73%;pharmacists’ participation in antimicrobial drug monitoring and drug use evaluation, which accounted for 62. 37%;pharmacists’ participation in drug counsultation and education, which accounted for 58. 68%;pharmacists’ participation in adverse drug reaction monitoring and supervision, which accounted for 77. 32%. Conclusion:The development of clinical pharmacy in Guizhou province still lags behind, and the number of clinical pharmacists is insufficient, which can’ t meet the growing demand for personalized medicine. In particular, the development of clinical pharmacy is restricted by the limited pharmaceutical service. The cog-nition degree of pharmacist group in Guizhou province has been improved. However, the number and the service quality of clinical pharmacists need to be improved further.

Conjugal plasmid pGH112 has been developed based on the replicons of Streptomyces coelicolor plasmid SCP2 and E. coli ColE. The plasmid contains ampicilin resistance gene(amp) for selection in E. coli and thiostrepton resistance gene (tsr) for selection in Streptomycetes, and a 0.76 kb oriT fragment of (IncP) RK2. Conjugal transfer of pGH112 was performed from E. coli to S. coelicolor A3(2), S. avermitilis, S. lividans TK54, S. toxytricini NNRL15443, S. venezuelae ISP5230 and Sacc. erythraea by conjugation, results show that the plasmid was able to transfer efficenctly from E. coli to Streptomycetes, was stably inherited in the recipients. pGH113 was constructed from pGH112 by combining the constitutive ermE promoter with green fluorescent protein gene(gfp).

Nephron sparing surgery ( NSS ) has become the standard treatment of small renal cancer . NSS have the similar curative effect compared with radical nephrectomy and preserve the kidney fuction. However, positive surgical margins after NSS is increasing and has attracted more and more attention. We will discuss positive surgical margins related factors and how to reduce the positive surgical margins in this review.

To investigate the optimum harvesting time and utilization of mulberry leaves during different growth periods based on the content of alkaloids and flavonoids, 88 samples of 11 species of mulberry leaves were collected and analyzed. UPLC-TQ/MS method was applied and the results showed that the ingredients of alkaloids and flavonoids in mulberry leaves are quite different in different growth periods and different species. There was a sharp decline of the average content of alkaloids in all samples from October, while the content of flavonoids dropped either from October but with less volatile. The content of flavonoids in M. atropurpurea was much higher than alkaloids, while M. australis was opposite completely. There was a sharp decline of alkaloids in M. cathayana and M. mongolica from Tuly to August, however, the content of alkaloids and flavonoids in M. alba is neither too high nor too low. In summary, it is more suitable to harvest tender mulberry leaves harvested from the end of September to beginning of October that provide a scientific evidence for rational harvest and comprehensive utilization of mulberry leaves.

AIMTo explore the relationship between expression of signal transduction and activators of transcription 3 (STAT3) gene and proliferation of rat pulmonary arterial smooth muscle cells (PASMCs) under hypoxia conditions.

METHODSAfter primarily cultured rat PASMCs was treated with AG490 and then exposed to hypoxia, the tyrosine-phosphorylated STAT3 protein were detected at 2 h, 6 h, 12 h, 16 h, 24 h of exposure to hypoxia by semi-quantitive RT-PCR (sqRT-PCR) and Western blot respectively. The expression of c-myc mRNA was analyzed by sqRT-PCR. 3H-TdR incorporation was used to detect the cell proliferation.

RESULTSThe level of tyrosine-phosphorylated STAT3 increased at 6 h and peaked at 12 h. The expression of c-myc mRNA increased after 2 h of hypoxia and reached maximal level at 4 h, then declined at 6 h and to the basal levels at 12 h. With the prolonging of hypoxia time, 3H-TdR incorporation in PASMC under hypoxia conditions was significantly higher. AG490 inhibited proliferation of PASMCs by preventing STAT3 tyrosine phosphorylation and the expression of c-myc under hypoxia conditions.

CONCLUSION(1) The activation of STAT3 and c-myc gene might play an important role in the early stage of hypoxia-induced PASMCs proliferation. (2) STAT3 upregulated the expression of c-myc during the proliferation of PASMCs induced by hypoxia.

OBJECTIVEto explore the potential role of apolipoprotein A5 (apoA5) on the hypertriglyceridemia (HTG)-lowering effects of statin.

METHODStwenty-four Sprague-Dawley rats were randomized into 3 groups: (1) control group (n = 8), with no special treatment; (2) HTG group (n = 8), treated with 10% fructose water for 6 weeks; (3) statin group (n = 8), treated with 10% fructose water for 2 weeks and cotreated with atorvastatin 10 mg×kg(-1)×d(-1) for another 4 weeks. Body weight, fasting plasma lipids and the hepatic expressions of apoA5 and peroxisome proliferator activated receptor (PPAR)α were determined. In separate in vitro experiments, we tested the effects of atorvastatin on TG and the expressions of apoA5 and PPARα in HepG2 cells.

RESULTS(1) at 6 weeks, plasma TG was higher in rats in HTG group than in controls, which was significantly reduced in statin group (both P < 0.05). (2) Rat hepatic apoA5 expression in HTG group was significantly lower than in control group and was significantly higher in statin group than in HTG group (both P < 0.05). (3) Similarly, rat PPARα mRNA expression in HTG group was lower than in control group and was higher in statin group than in HTG group (both P < 0.05). (4) Statin significantly upregulated the expressions of apoA5 and PPARα and decreased TG in HepG2 cells. The above effects induced by statin was blocked in the presence of PPARα inhibitor.

CONCLUSIONSupregulation of apoA5 expression contributes to TG lowering effect of statin via PPARα signaling pathway.

BACKGROUNDIncreased triglyceride (TG) occurs in patients with acute coronary syndrome (ACS), and apolipoprotein AV (apoAV) has been shown to lower TG levels. In the present study, we investigated plasma apoAV level and its relationship with TG and C-reactive protein (CRP) in ACS patients.

METHODSA total of 459 subjects were recruited and categorized into control group (n = 116), stable angina (SA) group (n = 115), unstable angina group (n = 116) and acute myocardial infarction group (n = 112). Plasma apoAV level was measured by a sandwich ELISA assay.

RESULTSCompared with controls ((100.27 +/- 22.44) ng/ml), plasma apoAV was decreased in SA patients ((76.54 +/- 16.91) ng/ml) but increased in patients with unstable angina ((330.89 +/- 66.48) ng/ml, P < 0.05) or acute myocardial infarction ((368.66 +/- 60.53) ng/ml, P < 0.05). Inverse correlations between apoAV and TG were observed in the control or stable angina groups (r = -0.573 or -0.603, respectively, P < 0.001), whereas positive correlations were observed in the patients with unstable angina or acute myocardial infarction (r = 0.696 or 0.690, respectively, P < 0.001). Furthermore, a positive relationship between apoAV and CRP was observed in the ACS patients but not in the non-ACS subjects.

CONCLUSIONThe plasma apoAV concentration is increased and positively correlates with TG and CRP in ACS patients.

OBJECTIVETo explore the relationship between serum apolipoprotein A5 (ApoA5) and lipid profile or high sensitive C-reactive protein (hs-CRP) in patients with acute coronary syndrome (ACS).

METHODSSerum apoA5 and hs-CRP levels were measured by ELISA and immunoturbidimetry in control subjects (n = 232), patients with stable angina (SA, n = 127), unstable angina (UA, n = 116) and acute myocardial infarction (AMI, n = 112). Triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were also measured.

RESULTSCompared with controls [(108.7 +/- 23.2) microg/L] and SA patients [(78.3 +/- 20.2) microg/L], serum ApoA5 level was significantly increased in UA [(340.6 +/- 63.5) microg/L] and AMI patients [(373.2 +/- 73.8) microg/L] (all P < 0.05). ApoA5 was positively correlated with TG (r = 0.63 and 0.67, respectively, all P < 0.05) and hs-CRP (r = 0.57 and 0.55, respectively, all P < 0.05) in UA and AMI patients but there were no significant correlations between ApoA5 and TC, HDL-C and LDL-C in ACS patients (all P > 0.05).

CONCLUSIONIncreased serum apoA5 level and the positive correlation between ApoA5 and serum TG and hs-CRP in ACS patients might reflect increased inflammation responses in ACS patients.

Lymphatic leakage and lymphatic cysts are common complications after radical resection of middle- and high-risk prostate cancer. There are many treatment methods but the effect is not accurate. This article reports two patients who were diagnosed by lipiodol lymphangiography under ultrasound guidance and used a mixture of n-butyl cyanoacrylate and lipiodol to embolize lymphatic leakage. Among them, one patient achieved success after one session of interventional embolization. Another patient achieved success after 3 interventions and embolization. Two patients had no complications related to lymphatic interventional therapy, and no lymphatic leakage recurred during the 3-month follow-up. Ultrasound-guided lymphangiography and lymphatic embolization through the inguinal lymph nodes are a feasible option for the treatment of refractory lymphoma leakage
