Background Senescence marker protein 30 (SMP30) is a new calcium regulatory protein,which plays anti-oxidation,stable calcium and anti-apoptosis roles in vivo.Researches determined that the expression of SMP30 in human cells gradually decreased as ageing.However,the study on the relationship between SMP30 and age-related cataract is rarely.Objective The aim of this study was to investigate the expression of SMP30 in lens epithelial cells (LECs) of different ages of cataract patients.Methods This study was approved by Ethic Commission of the First Affiliated Hospital of Guangxi Medical University.A non-randomized controlled trail was designed.The samples of the anterior capsular membrane of lens were collected during the cataract surgery from the children group (1-18 years),youth group (19-45 years),mid adult group (46-60 years) and elder group (>60 years) and 12 pieces of capsular membrane for each group.In addition,12 pieces of lens capsular membrane from normal donors aged 19-45 years were obtained as normal control group.The expression of SMP30 in the samples was detected by indirect immunofluorescence method.The average fluorescent values were calculated as absorbance (A) / area.Results SMP30 was expressed in LECs of different groups with the green fluorescence primarily in the cytoplasm.The mean fluorescence intensity was 0.185±0.020,0.181±0.034,0.207±0.018 and 0.126±0.027 in the children group,youth group,mid adult group and elder group,respectively,which were significantly enhanced than 0.087±0.007 of the normal control group(q=3.96,3.82,4.01,3.55,all at P<0.01).No significant differences in the expression of SMP30 among the children group,youth group and mid adult group (all at P>0.05).However,the expression of SMP30 in LECs in the elder group was significantly lower than that in the children group,youth group and mid adult group (q =3.42,3.21,3.80,all at P< 0.05).Conclusions Expression of SMP30 in LECs dramatically increases in cataract patients,suggesting that SMP30 may be a protective factor for LECs.But SMP30 contents are lower in age-related cataract patients,which may be one of causes of senior cataract.

Chinese Journal of Practical Nursing 2021;37(19):1496-1501
Objective:To explore the effects of meditation on patients underwent urodynamic examination.Methods:Totally 90 patients with benign prostatic hyperplasia who underwent urodynamic examination in the Department of Urology at the hospital from September 2018 to December 2019 were enrolled in the present study. They were assigned to experimental group and control group, with 45 cases in each group. The control group received routine nursing, basis on this, the experimental group carried out meditation training. The examination time, examination success rate as well as the incidence of complications were recorded between two groups. The systolic blood pressure, diastolic blood pressure and heart rate was compared at 10 min before the start of examination, 10 min after the start of examination, 10 min after the end of examination, respectively. In addition, the psychological stress was assessed by Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) at 1 day before the start of examination, 1 hour before the start of examination and 10 min after the end of examination.Results:The examination time were (33.56±4.95) min and the incidence of hematuria were 4.4% (2/45) in the experimental group, significantly lower than (36.42±6.32) min and 17.8% (8/45) in the control group, the difference was statistically significant (t value was 2.460, χ 2 value was 4.050, P<0.05). At 10 min before the start of examination, 10 min after the start of examination, the systolic blood pressure and diastolic blood pressure were (129.18±10.99) mmHg (1 mmHg=0.133 kPa), (130.73±11.81) mmHg and (89.42±14.50) mmHg, (98.36±15.51) mmHg in the experimental group, significantly lower than (135.93±10.17) mmHg, (139.49±10.64) mmHg and (96.29±13.85) mmHg, (105.80±12.02) mmHg in the control group ( t values were 2.297-3.695, P<0.01 or 0.05); at 10 min before the start of examination, 10 min after the start of examination, 10 min after the end of examination, the heart rate were (85.53±11.82) times/min, (90.51±8.82) times/min, (74.09±8.20) times/min in the experimental group, significantly lower than (92.80±11.95) times/min, (95.84±10.02) times/min, (77.60±8.51) times/min in the control group, the difference was statistically significant ( t values were 2.900, 2.680, 1.992, P<0.01 or 0.05). At 1 hour before the start of examination, the SAS and SDS scores were (54.42±3.85) pionts and (54.11±4.65) points in the experimental group, significantly lower than (58.44±7.37) pionts and (56.11±4.48) pionts in the control group, the difference was statistically significant ( t values were 3.247, 2.079, P<0.01 or 0.05). Conclusion:The meditation can help to relieve the physiological and psychological stress of patients who underwent urodynamic examination, shorten the examination time as well as reduce complications.

Objective:To investigate the feasibility and safety of suprapubic bladder puncture and gland fixation in transurethral enucleation of the prostate.Methods:The clinical data of 15 patients with benign prostatic hyperplasia admitted to the First Affiliated Hospital of Guangxi Medical University from January 2020 to June 2020 were retrospectively analyzed. The age was (70.27±5.35) years old, preoperative serum prostate-specific antigen (PSA) level was (3.03±1.37) ng/ml, preoperative total prostate weight was 80.3(70.49, 96.78)g, preoperative postvoid residual urine volume(PVR)was 80 (55, 108)ml, and the maximum urine flow rate (Q max) was (6.13±2.25) ml/s. The international prostate symptom score(IPSS) was 25(22, 27), quality of life (QOL)score was 5(5, 6), international erectile function index-5 (IIEF-5) score was (15.38±5.10). All 15 patients underwent conventional transurethral plasma enucleation of prostate by using the three-lobe method, and the enucleated gland was pushed into the bladder completely. Then a laparoscopic pneumoperitoneum needle was used to perform suprappubic cystipuncture, and ureteral grasping forceps were inserted through the outer sheath. The forceps were used to fix the enencied gland. A rapid harvesting electric resection was performed in the broad space of the bladder, and the Ellick was rinsed to remove the tissue fragments. Surgical indicators and complications were recorded. The improvement of subjective score (IPSS, QOL, IIEF-5) and objective index (Q max, PVR) was compared between preoperative and postoperative. Results:All the 15 operations were completed successfully and there were no complications such as blood transfusion, capsule perforation, transurethral resection syndrome, bladder injury, bladder puncture site laceration and bleeding. The weight of resected prostate tissue was 44(40, 60)g, with blood loss (79.20±18.93)ml.The time of enucleation operation was (54.13±10.88)min, with harvest cutting time (14.67±2.50)min, evisceration efficiency (0.89±0.08)g/min, harvesting efficiency (3.26±0.36)g/min, bladder irrigation time (2.47±0.52) d. The time of indwelling catheter was (3.73±0.80)d.The postoperative hospital stay was (4.40±0.91) d. Temporary urinary incontinence occurred in 1 case after operation. All patients were followed up for 6 months after operation. The IPSS score was 3(2, 3), QOL score was 0(0, 1), IIEF-5 score was (20.12±2.30), Q maxwas (21.80±2.14) ml/s and PVR was 10(5, 15)ml, which were all significantly different compared with those before surgery ( P<0.05). The symptoms of the patients were significantly improved. Conclusions:Transurethral plasma enucleation of prostate combined with suprapubic bladder puncture and fixed gland is effective in the treatment of benign prostatic hyperplasia. The subjective symptoms and objective examination of patients have been significantly improved, and no adverse operation-related complications have occurred. It is a suitable method for enucleation of prostate in units which are not equipped with transurethral tissue planer.

Fibromyalgia syndrome (FMS) is a refractory, chronic non-articular rheumatic disease characterized by widespread pain throughout the body, for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies, and some non-drug therapies, such as acupuncture, Tai Chi, and Ba-Duan-Jin, have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine (TCM) by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine, the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine, including rheumatology, psychology, acupuncture and moxibustion, and encephalopathy, with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS, mitigation of common non-specific symptoms, preferential analgesic therapy, TCM pathogenesis and treatment advantages, and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis, poor patient participation, and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems, this paper suggests that rheumatologists should serve as the main diagnostic force of this disease, and they should improve patient participation in treatment decision-making, implement exercise therapy, and fully utilize the holistic and multidimensional features of TCM, which is effective in alleviating pain, improving mood, and decreasing adverse events. In addition, it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment, which is expected to improve the standard of diagnosis and treatment of FMS in China.
