Objective Effects of aqueous extract from Lishi No.5 formula on concentration of intracellular free-calcium fluorescent intensity in neurons. Methods Hippocampus neurons of 1-day newborn SD rats were cultured with conventional culture technique. The cells cultured for 9-12 days were used for experiment. Intracellular free calcium fluorescent intensity of neurons cultured under different conditions was assayed with confocal microscopic calcium image technique after loading of Fluo-3/AM. Results Free-calcium concentration was enhanced by aqueous extract from Lishi No.5 formula, this concentration was up to 126.35?9.35nmol/L, but the concentration is at normal scope; L-type calcium channel blocker Nifedipine may block the effect of aqueous extract from Lishi No.5 formula enhancing intracellular free-calcium concentration in part, it make intracellular free-calcium concentration down to 90.75?10.15nmol/L, but Nifedipine itself also decreased markedly free-calcium concentration to 40.65?5.65nmol/L. NMDA increase Markedly calcium fluorescent intensity, the effects of NMDA was decreased notably after pre-treating with aqueous extract from Lishi No.5 formula. The effect of MK-801, an antagonist of NMDA receptor, on inhibition of NMDA increasing free calcium fluorescent intensity was significantly reduced after pretreatment of aqueous extract from Lishi No.5 formula. Conclusion Aqueous extract from Lishi No.5 formula maybe bidirectional adjust intracellular free calcium concentration via enhancing L-type calcium channel activity and blocking NMDA receptor in part.

Objective To study the effect of S2-protein from SARS coronavirus on the chloride channel currents in A549 cells and its possible cellular mechanisms. Methods The chloride channel currents were recorded in cultured A549 cells by using the whole-cell mode of patch clamp techniques. The experiments were divided into four groups: Control group: chloride channel currents were recorded in untreated A549 cells; S2 protein group: currents were recorded in A549 cells treated with S2 protein (final concentration 50?g/ml); calphostin C + S2 protein group: the effect of S2 protein on the currents in A549 cells pretreated with calphostin C (0.1mmol/L) for 10 minutes; SB203580+S2 protein group: the effect of S2 protein on the currents was examined with the solution containing SB203580 (20?mol/L). Results The currents of chloride channel in normal A549 cells showed outwardly rectifying properties and were insensitive to both TEA and amiloride, but were significantly inhibited both by SITS and DIDS (P

Results The postive expression rate of CD44v6 in normal renal tissues and primary renal cell carcinoma tissues was 15 00% and 66 67% respectively with significant difference (P

Objective: To investigate the effects of plateau environment exposure on the reproductive system of male rats, so as to provide the reference for mechanisms of reproductive damage in plateau environment. Methods: Sixty SPF-grade 12-week-old male Wistar rats were randomly divided into the plain-exposed group, the 1 day-, 3 day-, 7 day-, 14 day- and 28 day- plateau-exposed groups. The rats in the plain-exposed group were raised under normal conditions for 28 days, while the rats in the plateau-exposed groups were raised in a simulated high-altitude plateau chamber. After the completion of the designated feeding periods, the rats were sacrificed under anesthesia, and testicular tissue and abdominal aortic blood were collected to detect the testicular index and evaluate sperm quality. Histological and cellular morphologies of the testicular tissue were analyzed. Additionally, the levels of malondialdehyde (MDA), superoxide dismutase (SOD) and reactive oxygen (ROS) in the testicular tissue were determined, along with serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone (T). Conclusions Plateau environment may cause a decrease in testicular index and sperm quality, impair mitochondrial function, induce oxidative stress, and thus affect reproductive system of male rats. However, there are signs of self-repair in the reproductive system with the increase of exposure duration.

OBJECTIVE: Anatomic variation of renal artery existed in donor kidney, and whether the variation would affect clinical effects is unconfirmed. This paper is aimed to study the outcomes of in vitro reconstruction of malformed renal blood vessels on outcome of kidney transplantation. METHODS: Patients treated with kidney transplantation at Department of Urology, Lanzhou General Hospital of Chinese PLA were selected; including 27 cases underwent kidney transplantation with malformed blood vessels. Seventeen of them had accessory renal artery, 10 of them with two or three renal arteries. Additional 22 patients transplanted with normal kidney during the same period were selected as the control group. Bench surgery with microsurgical techniques was employed for the repair of the vessels, which included 11 cases of end to end anastomosis of arteries, 6 cases of end to side anastomosis of arteries, 6 cases of side to side conjoined anastomosis of arteries, and 4 cases of renal artery lengthening with an interposition of donor or recipient iliac artery. The hemorrhage, hypertension, renal arterial stenosis, delayed graft function, incidence rate of acute rejection, and the serum creatinine level were followed up.RESULTS: Totally 49 cases were received a mean 2-year follow-up, and no death occurred in both groups. Two cases in the experimental group, and 3 cases in the control group were suffered hypertension or hypertension aggravated, the difference had no significant (P =0.673). No arterial stenosis occurred during the follow up. In the experimental and control groups, the incidence of delayed graft function was 20% and 14%, the incidence of acute rejection was 13% and 5%, and mean serum creatinine at 2 year was (119±11) and (127±8) μmol/L, respectively, the difference was not significant between two groups (P=0.179, 0.385, 0.658).CONCLUSION: Donor kidneys with malformed vascular can be used for transplantation after bench reconstruction, which do not influence the outcome of kidney transplantation.

Objective:To explore the changes and clinical significance of inflammatory indices of urogenic sepsis with different severity.Methods:A retrospective case-control study was used to analyze the clinical data of 71 patients with urogenic sepsis admitted to 940th Hospital of PLA Joint Logistics Support Force from January 2010 to April 2018, including 34 males and 37 females, aged 39-96 years [(63.1±18.3)years]. The patients were divided into three groups according to the clinical diagnostic criteria for septic shock and sepsis according to the 2014 edition of the Chinese Urology Surgical Guidelines for Diagnosis and Treatment: 21 cases in sepsis group [sequential organ failure assessment (SOFA) score of 3.0 (2.0, 3.0)points], 21 cases in severe sepsis group [SOFA score of 9.0 (6.0, 11.0)points], and 29 cases in septic shock group [SOFA score of 15.0 (14.0, 16.0)points]. Spearman correlation analysis was used to analyze the correlation of inflammatory indicators with SOFA, including white blood cell count, percentage of neutrophils, C-reactive protein, interleukin-6, procalcitonin, fibrinogen, D-dimer, and platelet. Multiple linear regression analysis and stepwise regression weighted analysis were performed to analyze the relation between inflammatory indicators and sepsis severity. Levels of each inflammatory indicator was detected and compared among the groups.Results:① Spearman correlation analysis: percentage of neutrophils, D-dimer, interleukin-6, procalcitonin and SOFA scores were significantly positively correlated, with the r s value of 0.738, 0.712, 0.31, 0.795, respectively ( P<0.01); platelet and SOFA scores were significantly negatively correlated, with the r s value of -0.661 ( P<0.01). ② Multiple linear regression analysis: percentage of neutrophils, platelet, D-dimer, procalcitonin and SOFA score were significantly correlated ( P<0.01); Stepwise regression weighted analysis suggested that the model linear relationship and fit was good. ③ Inflammatory index comparison: percentage of neutrophils in sepsis group, severe sepsis group and septic shock group was 82.30 (76.25, 88.45), 90.50 (86.55, 93.85), 95.10 (92.05, 97.95), respectively; level of platelet was 183.01 (144.50, 246.50)×10 9/L, 149.11 (81.04, 207.00)×10 9/L, 81.26 (50.01, 93.50)×10 9/L, respectively; level of D-dimer was 0.98 (0.71, 1.74)mg/L, 3.45 (1.79, 5.56)mg/L, 7.19 (4.26, 11.63)mg/L, respectively; level of procalcitonin was 0.55 (0.21, 1.09)ng/ml, 5.45 (3.74, 11.80)ng/ml, 17.68 (13.97, 26.75)ng/ml, respectively. There were significant differences in above indicators among the groups ( P<0.05). Conclusions:The serum levels of procalcitonin, percentage of neutrophils, D-dimer and platelet are positively correlated with the severity of urogenic sepsis. While combined detection of those indicators can better predict the severity of the sepsis.

The diagnosis of bone metastasis of prostate cancer (PC) is of great significance to the treatment and prognosis of patients with PC.Bone scan is the most commonly used in the early diagnosis of bone metastasis, but its specificity is low and there is a high false positive.In recent years, with the in-depth study of the application of CT, MRI, emission computed tomography (ECT), positron emission computed tomography/computed tomography (PET/CT) and deep learning algorithm-convolutional neural networks (CNN) in the diagnosis of bone metastasis, the combined application of various auxiliary parameters in the diagnosis of bone metastasis has significantly been improved. The therapeutic effect of PC patients with bone metastasis can also be evaluated, which is expected to achieve the treatment of bone metastasis as well as diagnosis. By systematically expounding the research progress of the above-mentioned techniques in the diagnosis of bone metastasis, it can provide clinicians with new methods for the diagnosis of bone metastasis and improve the diagnostic efficiency for bone metastasis.

【Objective】 To investigate the psychological status of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), and to analyze the effects of anxiety on the total National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) in patients in Ngari Prefecture of Tibet. 【Methods】 CP/CPPS patients treated during Oct.2019 and Oct.2021 were involved and divided into anxiety group and non-anxiety group. The non-anxiety group received routine drug treatment, while the anxiety group received drugs and psychological intervention. 【Results】 A total of 117 patients were involved, including 68 in the anxiety group and 49 in the non-anxiety group. There were no statistical differences between the two groups in terms of age, body mass index (BMI), marital status, smoking history, and education level (P>0.05). The total NIH-CPSI score in the anxiety group (18.53±3.47) was higher than that in non-anxiety group (15.67±3.33), which was mainly manifested by the increase of pain and decrease of quality of life scores. Further stratification of anxiety level revealed that quality of life score and total NIH-CPSI score increased as anxiety symptoms worsened. After drug treatment, pain and urination symptoms were improved in the non-anxiety group, but the quality of life score and total NIH-CPSI score did not change significantly. After psychological intervention, the anxiety group had lower total NIH-CPSI score and other scores. 【Conclusion】 It is not uncommon for CP/CPPS patients to have a comorbidity of anxiety. The increase in the total NIH-CPSI score is caused by the increase of pain score and decrease of quality of life score. Active psychological intervention can improve anxiety, urinary symptoms, pain symptoms and quality of life.

BACKGROUNDWaldenström macroglobulinemia (WM) is an uncommon lymphoid malignancy. The characteristics and prognosis of WM have never been systematically studied in the East.

METHODSWe analyzed the clinical characteristics and the prognostic factors of 90 Chinese WM patients, and compared them with the Western reports.

RESULTSThe median age was 62 years old with a male-to-female ratio of 3.74. The most common symptoms at diagnosis were fatigue (77.8%) and bleeding (20%), while only 6 patients (6.7%) were asymptomatic. In the univariate analysis, age >62 years, thrombocytopenia, leucopenia, cytopenias ≥ 2, and high risk on the international prognostic scoring system for WM were the adverse risk factors, but only age >62 years and ≥ 2 cytopenias were the independent prognostic factors in the multivariate analysis. Using age <62 years and ≥ 2 cytopenias, three significantly different prognostic groups could been distinguished, with 5-year overall survival of 71.6%, 48.6%, and 17.0% (P < 0.001).

CONCLUSIONDistinct characteristics exist in WM in China compared to the West and we describe a new simple prognostic model for newly diagnosed WM patients.
