1."The ""3B"" in the clinical management of non-neurogenic male lower urinary tract symptoms"
Chinese Journal of Urology 2017;38(5):326-329
Lower urinary tract symptoms (LUTS),consisting storage,voiding and postmicturition symptoms,is a comprehensive definition involving multiple organs.There has been an increasing emphasis on the integrated management of non-neurogenic male lower urinary tract symptoms.Instead of focusing on the enlarged prostate,the current treatment has paid more attention on the entire urinary tract as well as multiple organ factors.Therefore,we provided a literature review and summarized the key points during the management of male LUTS as 3B,namely beyond prostate,beyond surgery and beyond urology.

AIM To study the effect of ZMS, an active component of traditional Chinese herb Zhimu, on two neurotrophins in brains of aged rats. METHODS The function of learning and memory was detected by Y-maze. BDNF and NGF in brain were determined by ELISA. Rats were divided into three groups, young, aged, and aged treated with ZMS for two months at a dose of 18mg/kg/d which is equivalent to the dose recommended for clinical use. RESULTS The learning and memory ability are impaired in aged animals and ZMS is effective in improving the learning and memory ability of such animals. BDNF content of whole brain is lowered in aged rats when compared with young rats. ZMS is able to raise the BDNF content to a higher level. The NGF contents of young, aged and aged treated with ZMS groups were not significantly different from each other. CONCLUSIONS ZMS is able to raise brain BDNF in aged rats and thus to protect cholinergic neurons from degeneration. It is very probable that this action is one of the mechanisms of ZMS in improving the ability of learning and memory.

Objective; To express and purify HCA518 protein and prepare its monoclonal antibody ( McAb). Methods: The HCA518 protein was expressed with gene recombinant technique in prokaryotic system and purified with nickel chelate nitrilotriacetic acid(Ni-NTA) affinity chromatography column. Hybridoma cell lines that secreted anti-HCA518 McAb were established by cells fusion and screened by enzyme linked immunosorbent assay( ELISA). The specificity of anti-HCA518 McAb wa3 identified by Western blot assay. The HCA518 protein in tumor cells was stained by immunoflourescence assay. Results: Rcombinant HCA518 protein was expressed with a purity of 98%. Two hybridoma cell lines was selected and anti-HCA518 McAb was purified from mice ascites. The titers of anti HCA518 McAb in ascites were 1?10-4 and 5?10-4 respectively. The antibody belonged to IgG2b subtype and IgM. Anti-HCA518 McAb specifically reacted with recombinant HCA518 protein and tumor cells'nuclear protein (P100). The HCA518 protein was mainly located in cell nucleus. Conclusion: Stable hybridoma cell lines that secreted anti-HCA518 McAb have been established and anti HCA518 McAb was prepared with high specificity. It has important significance for detecting HCA518 protein in tumor tissues and determining malignant proliferation status of tumor cells and predicting its prognosis.

Aim To observe the effect of ZDY102, a C25 stereo-isomer of ZMS, the active component of Zhimu, on brain M receptor density of dementia model animals and the correlation with its effect on learning/memory ability. Methods The rats were randomly divided into five groups: control group, model group, model given orally for 2 months with 3.6 mg?kg -1?d -1 of ZDY102 treatment, model treated with 9.0 mg?kg -1?d -1 of ZDY102, and model treated with 18.0 mg?kg -1?d -1 of ZDY102. Dementia model was produced by single unilateral injection of 4 ?l of normal saline containing 4 ?g of ?-amyloid (25~35) and 1 ?g of ibotenic acid into right basal ganglion region with the aid of a stereotaxic equipment. The brain muscarinic receptor density was analyzed with single-site binding assay using 3H-quinuclidinyl benzilae(QNB). The learning/memory ability was measured by Y-maze performance. Results Two months after model production, the learning and memory ability as well as the density of muscarinic receptor in brain were significantly decreased in model rats compared with those in control rats. Parallel models treated with daily oral administration of ZDY102 for two months improved in learning and memory ability and their muscarinic receptor density was significantly increased when compared with model rats. The correlation coefficient between total M receptor densities and the learning/memory ability was significant when examined with linear regression. Conclusion ZDY102 can significantly improve the learning and memory ability and increase the brain muscarinic receptor density of the model. Since brain muscarinic receptors are closely correlated to learning and memory, up-regulation of M receptor density might play a very important role in the therapeutic effect of ZDY102.

Aim To establish and compare asthma models among different strains of obese mice. Methods Different strains of SPF female mice, namely Kunming ( KM ) , C57BL/6J and BALB/c mice, were randomly divided into four groups ( control group, asthma group, obesity group and obese asthma group). The mice were fed a high-fat diet or a normal diet for 12 weeks, following which they were sensitized and challenged with ovalbu-min ( OVA) or phosphate-buffered saline ( PBS) . Body weight, fat weight, liver weight, Lee′s index, OVA-specific IgE concen-tration in bronchoalveolar lavage fluid ( BALF) , serum total cho-lesterol ( TC) and triglyceride ( TG) levels, and lung and adi-pose morphologies were evaluated. The specific airway resistance ( sRaw) was measured using double-chamber plethysmography. Results The mice on a high-fat diet showed a more rapid in-crease in body weight compared with those on a normal diet. Af-ter 12 weeks of feeding, body, fat, and liver weights and Lee′s index were higher for the obese mice than for the lean mice. The adipocyte cross-sectional area was significantly greater in the obese BALB/c and KM mice than in their lean counterparts;the C57BL/6J groups showed no significant differences. The BALB/c mice demonstrated more significant symptoms of acute asthma, local inflammation and airway hyper-responsiveness ( AHR ) . Conclusion Compared with C57BL/6J and KM mice, BALB/c mice fed a high-fat diet and sensitized and challenged with OVA provide the most suitable model for evaluating the relationship between obesity and asthma.

Objective:To evaluate the application values of small FOV surface coil and BLADE sequence in MR imaging on assessment of talar cartilage injury of ankle joint under traction.Methods:The clinical and imaging data of 53 patients with ankle cartilage injury in the Affiliated Suzhou Hospital of Nanjing Medical University from December 2018 to July 2020 were prospectively analyzed. All patients underwent the following MR sequences: sequence Ⅰ was fast spin echo proton density weighted (FSE-PD) BLADE sequence with surface coil small FOV, and sequence Ⅱ was FSE-PD-BLADE imaging of small FOV under horizontal load traction of ankle joint. Paired sample Wilcoxon rank sum test was used to compare the thickness of talus dome cartilage, cartilage space and subjective assessment score of image quality (including the outline of the upper surface of the cartilage at the injury, the thickness of the cartilage layer at the injury, the rupture of the cartilage at the injury, the relationship between cartilage and subchondral bone, subchondral bone collapse or trabecular fracture line) between sequence I and sequence Ⅱ.Results:There was significant difference in the thickness of central cartilage of talus between sequence Ⅰ and sequence Ⅱ [0.70 (0.60, 0.90) mm and 0.80 (0.70, 0.90) mm, Z=-2.900, P=0.004, respectively]. There was no significant difference in the thickness of medial and lateral talus cartilage between sequence Ⅰ and sequence Ⅱ (P>0.05). There were significant differences between sequence Ⅰ and sequence Ⅱ in the center [0.10 (0, 0.15), 0.89(0.63, 1.00) mm], medial [0.10(0, 0.31), 1.20(0.70, 1.25) mm] and lateral cartilage space [0.18(0.08, 0.23), 0.90(0.76, 0.94)mm] (all P<0.001). As for the subjective assessment score of talus cartilage injury, except for score in subchondral bone collapse or bone trabecular fracture line between sequence Ⅱ and sequence Ⅰ ( Z=-1.480, P=0.139), significant differences were found in all other scores ( P<0.05). Conclusion:MRI of the ankle under traction is safe and feasible. Under the condition of horizontal traction, small FOV surface coil combined with BLADE sequence can better display talus cartilage injury.
