ABSTRACT
Osteoarthritis is a prevalent global joint disease, which is characterized by inflammatory reaction and cartilage degradation. Cyasterone, a sterone derived from the roots of Cyathula officinalis Kuan, exerts protective effect against several inflammation-related diseases. However, its effect on osteoarthritis remains unclear. The current study was designed to investigate the potential anti-osteoarthritis activity of cyasterone. Primary chondrocytes isolated from rats induced by interleukin (IL)-1β and a rat model stimulated by monosodium iodoacetate (MIA) were used for in vitro and in vivo experiments, respectively. The results of in vitro experiments showed that cyasterone apparently counteracted chondrocyte apoptosis, increased the expression of collagen II and aggrecan, and restrained the production of the inflammatory factors inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), a disintegrin and metalloproteinase with thrombospondin motifs-5 (ADAMTS-5), metalloproteinase-3 (MMP-3), and metalloproteinase-13 (MMP-13) induced by IL-1β in chondrocytes. Furthermore, cyasterone ameliorated the inflammation and degenerative progression of osteoarthritis potentially by regulating the nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) pathways. For in vivo experiments, cyasterone significantly alleviated the inflammatory response and cartilage destruction of rats induced by monosodium iodoacetate, where dexamethasone was used as the positive control. Overall, this study laid a theoretical foundation for developing cyasterone as an effective agent for the alleviation of osteoarthritis.

OBJECTIVE@#To evaluate the accuracy of cardiac troponin (cTn) levels in the diagnosis of acute myocardial infarction (AMI) in patients with chronic kidney disease (CKD) and explore a potential strategy for improving the diagnostic accuracy.@*METHODS@#We retrospectively analyzed the data from patients with high-risk chest pain admitted in Zhujiang Hospital from January, 2018 to December, 2020, including 126 patients with and 272 patients without CKD, and 122 patients diagnosed to have AMI and 276 patients without AMI. The baseline clinical data of the patients and blood test results within 12 h after admission were collected.@*RESULTS@#In patients without AMI, cTnT level was significantly higher in those with co-morbid CKD than in those without CKD (P < 0.001), and showed a moderate negative correlation with eGFR (rs=- 0.501, P < 0.001), while cTnI level did not differ significantly between the two groups (P=0.72). In patients with CKD, the optimal cutoff level was 0.177 μg/L for cTnT and 0.415 ng/mL for cTnI for diagnosis of AMI, for which cTnI had a higher specificity than cTnT. The diagnostic model combining both cTnT and cTnI levels [P=eY/(1+ eY), Y=6.928 (cTnT)-0.5 (cTnI)-1.491] had a higher AUC value than cTn level alone.@*CONCLUSION@#In CKD patients, the cutoff level of cTn is increased for diagnosing AMI, and cTnI has a higher diagnostic specificity than cTnT. The combination of cTnT and cTnI levels may further improve diagnostic efficacy for AMI.

Objective:To study the actual effect of the use of personal protective equipment of the examined individuals, and provide reference and basis for the correct use of personal protective equipment and the radiological health administrative law enforcement.Methods:From February to June 2022, the imaging department of Qingdao Municipal Hospital selected 170 patients who underwent X-ray imaging examination (oral panoramic, dental radiography, DR photography, CT scanning), including 25 with oral panoramic and dental radiography, 60 with CT scanning and 60 with DR imaging. The thermoluminescent dosimeter was used to detect the ambient dose equivalent at the point of concern for 170 examined individuals who have used personal protective equipment to cover their sensitive parts, and to analyze the data detected at the same point as above when routinely using the same equipment.Results:There was a statistically significant difference in the dose equivalent at the same points inside and outside the lead neckband ( t=-2.23, P<0.05). There was no statistically significant difference in the dose equivalent at the same point inside and outside the lead collar during dental radiography ( P>0.05). During DR photography (chest PA, lateral and lumbar AP), the examined individuals were wearing lead aprons. Among them, there was a statistically significant difference in the dose equivalent at the same points inside and outside the lead aprons of children′s chest PA and adults′ chest PA ( U=10.00, 19.00, P<0.05). There was no statistically significant difference in the dose equivalent at the same points inside and outside the lead aprons of adult′s chest PA and lumbar AP ( P>0.05). When performing CT scan (chest or upper abdomen), there was a statistically significant difference in the dose equivalent at the same points of wrapped lead aprons( U=878.50, 11.00, P<0.05). Conclusions:The correct use of personal protective equipment is a complex technical problem. It is very important to fully and accurately understand the optimization principle of radiation protection and correctly use personal protective equipment for the examined individuals. The administrative punishment of radiation health on the use of personal protective equipment of the examined individuals should be cautious.
ABSTRACT
【Objective】 To explore the causes and management of nephrostomy catheter following percutaneous nephrostolithotomy (PCNL) entering the inferior vena cava. 【Methods】 A retrospective analysis was performed on the management of two cases of nephrostomy catheter entering the inferior vena cava. The causes, changes of minimally invasive treatment and prevention plans were discussed. 【Results】 Two patients underwent digital subtraction angiography (DSA) to restore the nephrostomy tube to the renal pelvis collecting system. No renal vein rupture or bleeding occurred during the operation, and the patients’ vital signs were stable. Nephrostomy tube was removed successfully after operation. The wound healing was good, and there was no secondary hemorrhage such as perirenal hematoma. The prognosis was good. 【Conclusion】 Although intravenous nephrostomy tube misplacement is an uncommon PCNL complication, the consequences are serous. One-step retraction displacement of nephrostomy tube to the renal collecting system can effectively manage nephrostomy catheter entering the inferior vena cava.
ABSTRACT

The incontinence quality of life (I-QOL) score, daily use of urine pad, 1-hour urine pad test, residual urine volume (RUV), and maximum flow rate (Qmax) were assessed before and after surgery. 【Results】 The total success rate was 79.5%, of which the cure rate was 56.4% and the improvement rate was 23.1%. The preoperative I-QOL score was (54.6±3.9), daily use of urinary pad was (3.6±0.7), and increase in weight of the 1-hour urine pad test was (33.6±5.0) g. Three years after surgery, the I-QOL score was (80.4±5.7), daily use of a urinary pad was (1.9±0.4), and increase in weight of the 1-hour urine pad test was (7.4±1.3) g. Compared to preoperative status, the I-QOL score, daily use of urine pad, and increase in weight of the 1-hour urine pad test 3 years after surgery improved significantly (P<0.05). During the mean follow-up of (61.4±20.5) months, no significant changes in the I-QOL score, daily use of a urinary pad, 1-hour urinary pad test, RUV or Qmax were observed, and no complications occurred. 【Conclusion】 Transobturator bulbourethral suspension with modified four-armed pelvic sling is an effective and safe procedure to treat post-prostatectomy incontinence. The long-term efficacy is satisfactory.
ABSTRACT
【Objective】 To compare the efficacy of transurethral columnar balloon dilation of the prostate (TUCBDP) and transurethral resection of prostate (TURP) in the treatment of small volume prostatic hyperplasia. 【Methods】 A total of 96 patients with small volume prostatic hyperplasia diagnosed in our hospital during Jan.2019 and Jan.2021 were enrolled and divided into the observation group and control group,with 48 patients in either group. The observation group received TUCBDP while the control group TURP. The International Prostate Symptom score (IPSS),Quality of Life Score (QOL), international index of erectile function-erectile function (IIEF-EF),maximum urinary flow rate (Qmax),postvoid residual urine (PVR) and maximum detrusor pressure (MDP) of the two groups were compared before surgery and 24 months after surgery. The surgery-related complications and occurrence of new or aggravated sexual dysfunction were observed. 【Results】 Both groups successfully completed the treatment. The operation time and indwelling catheterization time were shorter in the observation group than in the control group (P<0.05). The scores of QOL,IPSS and IIEF-EF,the levels of Qmax,PVR and MDP of both groups 24 months after surgery were significantly improved compared with those before surgery (P<0.05). The IPSS score of the observation group was lower than that of the control group 24 months after surgery (P<0.05),while the IIEF-EF score and Qmax of the observation group were higher than those of the control group (P<0.05). The incidences of surgery-related complications and new or aggravated sexual dysfunction were significantly lower in the observation group than in the control group (P<0.05). 【Conclusion】 TUCBDP is significantly effective in the treatment of small volume prostatic hyperplasia,showing greater advantages than TURP in improving postoperative IPSS,IIEF-EF score and Qmax,with higher safety.
ABSTRACT
Transperineal urethral anastomosis is currently an important treatment method for urethral stricture after pelvic fracture. After failure, this approach is still the main remedial operation. There is often a long segment atretic between the proximal and distal urethra in patients undergoing reoperation, and it is difficult to achieve tension-free anastomosis by simply pulling the proximal and distal ends, which is one of the important reasons for urethral anastomosis failure. This paper summarizes the failure factors of urethral repair surgery, the choice of reoperation, intraoperative details and answers to common difficult problems, in order to promote the theory and technical level of reconstructive urethral surgeons.
ABSTRACT
【Objective】 To investigate the clinical characteristics,treatment and prognosis of primary urethral cancer (PUC). 【Methods】 The clinical data of 24 PUC patients treated in our hospital during Jan.2013 and Jul.2022 were retrospectively analyzed. The patients were followed up to monitor the metastasis,recurrence and survival. 【Results】 The patients included 17 male and 7 female,aged (57.6±12.8) years. The main pathologic type was squamous cell carcinoma,followed by urothelial carcinoma. Altogether 23 patients underwent surgical treatment,and 8 of them received postoperative radiotherapy or chemotherapy. During the follow-up of 1 to 92 months,17 patients were followed up,3 of the them had local recurrence,1 had metastasis,and 5 died. Survival analysis showed that patients survived (63.3±10.6) months,with a 21-month survival rate of 64.8% and progression-free survival of 22 (9,72) months. 【Conclusion】 PUC is a rare malignant tumor with poor prognosis. For early and distal PUC,urethra-preserving surgery can be adopted;for proximal or advanced PUC,surgery combined with radiotherapy or chemotherapy is recommended.
ABSTRACT
Objective:To investigate the predictive value of stone composition prediction method based on dual-source stone energy spectrum CT for uric acid stones.Methods:The clinical data of 204 patients with urinary stones, 159 males and 45 females, admitted to Shanghai Sixth People's Hospital from July 2020 to July 2022 were retrospectively analyzed. The average age was (50.7±14.3) years. There were 187 cases of upper urinary tract (kidney, ureter) stones and 17 cases of lower urinary tract (bladder, urethra) stones. All patients underwent preoperative dual-source stone energy spectroscopy CT, measuring CT values at 150 kV and 100 kV, respectively, and the calculated dual energy ratio (Ratio) was used to predict stone composition. Of the 204 cases in this group, 33 cases underwent percutaneous nephrolithotomy and 171 cases underwent ureteroscopic lithotripsy. Postoperative stone specimens were analyzed for stone composition by infrared spectroscopy. Subject work characteristic (ROC) curves were used to analyze the efficacy of preoperative dual-source stone energy spectrum CT to predict uric acid stones.Results:In 204 patients, preoperative CT predicted 28 cases of uric acid stones and 176 cases of non-uric acid stones, including 136 cases of calcium oxalate stones, 38 cases of hydroxyapatite, and 2 cases of cystine stones. Postoperative IR spectral analysis detected 26 cases of uric acid stones and 178 cases of non-uric acid stones, including 129 cases of calcium oxalate stones, 47 cases of hydroxyapatite, and 2 cases of cystine stones. Compared with the preoperative CT results, there were 2 false positives and no false negatives in the classification of uric acid stones. The ROC curve showed that the sensitivity of the CT value for predicting uric acid stones at 100 kV was 96.2%, the specificity was 99.5%, and the area under the ROC curve (AUC) was 0.995, with the best prediction value of 620 HU.The sensitivity of the CT value for predicting uric acid stones at 150 kV was 96.2%, specificity was 85.5%, AUC was 0.916, and the best predictive value was 597.5 HU. The sensitivity of using Ratio values for predicting uric acid stones was 100.0%, specificity was 97.9%, AUC was 0.996, and the best predictive value was 1.14. The CT values for uric acid stones at 100 kV and 150 kV were (558.58±77.07) HU and (521.12±83.54) HU, CT values for calcium oxalate stones were (1 335.26±301.82) HU and (878.21±200.21) HU, CT values for hydroxyapatite were (1 104.09±203.61) HU and (710.38±178.44) HU, respectively.The CT values of cystine stones were (684.5±67.18) HU and (573.5±67.10) HU, respectively, and the differences between uric acid stones and other components were statistically significant ( P<0.01). The Ratio values of uric acid stones, calcium oxalate stones, hydroxyapatite, and cystine stones were 1.08±0.06, 1.52±0.08, 1.62±0.40, and 1.19±0.02, respectively, and the differences were statistically significant ( P<0.01) when comparing uric acid stones with other components. Conclusion:The CT and Ratio values of dual-source stone energy spectrum CT can effectively distinguish uric acid stones from other types of stones, and the accuracy, sensitivity, and specificity of this method for predicting uric acid stones are high.
ABSTRACT
Objective:To summarize the ideal strategy for the treatment of female hypospadias.Methods:The data of 12 female patients with hypospadias admitted to the Sixth People's Hospital Affiliated to Shanghai Jiaotong University School of Medicine from December 2011 to December 2019 were retrospectively analyzed. The patients was (31.0±16.6) years old (7-67 years old). Among them, 3 cases had a history of pelvic fracture trauma, 3 cases had a history of birth trauma, and the remaining 6 cases had no history of trauma and surgery. Among them, there were 6 cases of congenital hypospadias and 6 cases of acquired hypospadias. The clinical manifestations were urinary incontinence in 6 cases and dysuria in 6 cases. Examination of the normal position of the external opening of the genital urethra did not show the opening of the urethra, but moved down to different parts of the anterior wall of the vagina. All patients underwent urethral lengthening. For congenital hypospadias, the urethral plate is used to cut the coiled tube during the operation to prolong the urethra. For acquired hypospadias, the stenotic urethra was enlarged and lengthened with a labial pedicled flap coil. The subcutaneous fat pad of the labia majora was mobilized and transferred to the outside of the newly constructed urethra to prevent the occurrence of urethro-vaginal fistula and increase the pressure of the urethra. Five patients with significant urinary incontinence underwent bladder neck reconstruction at the same time. Anatomical success of the procedure was defined as the appearance of a normal-shaped external urethral opening beneath the clitoris. Functional success was defined as the absence of moderate to severe urinary incontinence after surgery, and the maximum urinary flow rate was >15ml/s during the 12-month follow-up period.Results:All operations were successfully completed. All patients had no perioperative complications, and were followed up for 18-96 months, with an average of 57.3±32.5 months. All patients were able to urinate spontaneously after operation, 4 cases of urinary incontinence disappeared, and 2 cases improved significantly; 4 cases of patients with strenuous urination urinated smoothly. The remaining 2 cases still complained of dysuria after operation, which was solved by subsequent urethral dilatation. The anatomical repair success rate was 100.0%(12/12) and the functional success rate was 83.3% (10/12).Conclusions:Urethral lengthening is an effective method for female hypospadias. The pedicled fat pad helps to increase urethral pressure and prevent fistulas. For female patients with hypospadias and severe urinary incontinence, bladder neck reconstruction is an ideal method. of the technique.
ABSTRACT
Objective:To summarize and analyze the current application status of oral mucosal graft (OMG) technique in the repair of ureteral strictures in China, and clarify the feasibility, safety and effectiveness of this technique.Methods:The 175 patients who underwent repair of ureteral stricture using oral mucosal patches from June 2015 to February 2022 were etrospectively analyzed in 14 medical centers in China, including 49 cases in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, 32 cases in Affiliated Seventh Medical Center of PLA General Hospital, 3 cases in The Second Hospital of Anhui Medical University, 6 cases in The First Affiliated Hospital of Zhengzhou University, 56 cases in Peking University First Hospital, 3 cases in Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, 3 cases in Shanghai Sixth People' s Hospital, 4 cases in General Hospital of Estern Theater Command, 4 cases in Lanzhou University Second Hospital, 2 cases in Guizhou Province People 's Hospital, 2 cases in Peking University People' s Hospital, 5 cases in Jinzhou First People's Hospital, 5 cases in The First Affiliated Hospital of Wannan Medical College, 1 case in Shandong Provincial Hospital. In this study, 127 patients (72.6%) used lingual mucosal patches, 32(18.3%) labial mucosa, and 16(9.1%) buccal mucosa. The surgical approach for OMG ureteral reconstruction was mainly minimally invasive, with robot-assisted laparoscopy in 84 patients (48.0%), traditional laparoscopic surgery in 87 patients (49.7%), and open surgery in only 4 patients (2.3%). There were 133 males and 42 females with an average age of (35.0±17.2) years. The mean body mass index (BMI) and stenosis length were (23.1±4.1) kg/m 2 and (4.7±1.8) cm, respectively. The stricture was located in the left ureter in 116 patients, right ureter in 58 case and bilateral ureter in 1 case. The most common causes of ureteral stricture were endoscopic surgery in 88(50.3%)patients, congenital stricture in 55(31.4%)patients, failed ureteroplasty in 29(16.6%)patients, history of extracorporeal shock wave lithotripsy in 13(7.4%)patients, radiotherapy history in 3(1.7%)patients and other causes in 6(3.4%)patients. Strictures were mainly located in the upper ureter, accounting for 61.7% (108/175 cases), followed by 36.0% (63/175) at the ureteropelvic junction and 2.3%(4/175)in the middle ureter. According to the surgical methods, the patients were divided into robot-assisted laparoscopic surgery group ( n=84), traditional laparoscopic surgery group ( n=87)and open surgery group ( n=4). Subgroup analysis of patients in robot-assisted laparoscopic and traditional laparoscopic surgery groups was performed. There were no significant difference in preoperative data between the two groups except for age (32.0±18.3) years vs.(37.0±15.9)years, P=0.040], BMI[(22.5±4.3)kg/m 2 vs. (23.7±3.6)kg/m 2, P=0.028], and etiology of stenosis [endoscopic injury, 34(40.5%) vs. 53(60.9%), P=0.012]. Preoperative hydronephrosis and stricture length were assessed by CTU and ureterography. Ureterography 7-9 weeks after surgery showed patency of the reconstructed segment, or no recurrence of hydronephrosis was judged as success. Evaluate the operation method, operation time, success rate, length of OMG in repairing ureteral stricture between laparoscopic and robot-assisted groups. Results:The overall success rate of oral mucosal graft repair surgery reached 97.7%(171/175). The success rate of ureteral reconstruction in the two groups were 96.4%(81/84)and 98.9%(86/87), respectively ( P=0.351), and the difference was not statistically significant. There was no significant difference for operation time, intraoperative blood loss, and mean oral mucosal length between the robotic and laparoscopic groups[(244.7±85.8) min and (222.7±83.5)min ( P=0.116), (58.9±38.6) ml and (68.4±45.5) ml ( P=0.217), (5.0±2.0) cm and (4.6±1.5) cm ( P=0.350)], respectively.Postoperative complications were reported in 23 (13.1%) patients, such as fever, urinary leakage, lymphatic leakage, infection, but only 2 (1.4%) cases patients had complications of Clavien-Dindo score ≥ Ⅲ. The two patients developed urinary stricture after surgery with failed conservative treatment, and no urinary stricture occurred following endoscopic treatment.The short-term (three months after surgery)incidence of complications in the site where the oral mucosa was taken, such as difficulty in opening mouth, pain, and swelling, was 12.0% (21/175), and there was no significant difference for oral complications between patients harvesting different length of mucosal graft. Conclusions:Ureteroplasty with oral mucosal graft is a safe, feasible and reliable technique for ureteral reconstruction. At present, minimally invasive technology is the main surgical approach for ureteroplasty, and there is no significant difference in operation time and success rate between robotic surgery and laparoscopic surgery.
ABSTRACT
Radical pelvic surgery is a surgical method mainly used to treat tumors in the pelvic cavity, and erectile dysfunction (ED) is a common sexual dysfunction after surgery. The incidence of ED after radical pelvic surgery is not uniformly understood due to differences in surgical approaches and methods of investigation. The main causes of postoperative ED include intraoperative neurovascular injury, psychosomatic factors and preoperative patient characteristics, with intraoperative injury to the neurovascular bundle being the most common. Studies have shown that the occurrence of postoperative ED can be prevented by active intervention, but still lack of effective treatment measures. This article reviews and summarizes the clinical epidemiological features and research progress in recent years on ED after radical pelvic surgery, and discusses specific measures for the prevention and treatment of postoperative ED.
ABSTRACT
This study retrospectively analyzed the clinical data of 28 male patients with urethral stricture who had complications during urethrography, including 14 cases of infection, 8 cases of urethral bleeding, 5 cases of contrast agent hypersensitivity, and 1 case of bladder rupture. The infection manifested as acute cystitis in 11 cases, acute pyelonephritis in 1 case, acute epididymitis in 1 case, and sepsis in 1 case. Hypersensitivity reaction was mild in 3 cases, moderate and severe in 2 cases. A child with bladder rupture was immediately transferred to open surgery for bladder repair. All patients were cured by corresponding treatment. The complications of urethrography have various manifestations and different degrees of severity, so we should pay attention to prevention and proper treatment.

Objective: To examine the feasibility and surgical approach of removing type D trigeminal schwannoma through nasal cavity and nasal sinus under endoscope. Methods: Eleven patients with trigeminal schwannoma who were treated in the Department of Otorhinolaryngology, Qilu Hospital of Shandong University from December 2014 to August 2021 were analyzed retrospectively in this study. There were 7 males and 4 females, aged (47.5±13.5) years (range: 12 to 64 years). The neoplasm involved the pterygopalatine fossa, infratemporal fossa, ethmoidal sinus, sphenoid sinus, cavernous sinus, and middle cranial fossa. The size of tumors were between 1.6 cm×2.0 cm×2.0 cm and 5.7 cm×6.0 cm×6.0 cm. Under general anesthesia, the tumors were resected through the transpterygoid approach in 4 cases, through the prelacrimal recess approach in 4 cases, through the extended prelacrimal recess approach in 2 cases, and through the endoscopic medial maxillectomy approach in 1 case. The nasal endoscopy and imaging examination were conducted to detect whether neoplasm recurred or not, and the main clinical symptoms during follow-up. Results: All the surgical procedures were performed under endonasal endoscope, including Gross total resection in 10 patients. The tumor of a 12-year-old patient was not resected completely due to huge tumor size and limited operation space. One patient was accompanied by two other schwannomas located in the occipital region and the ipsilateral parotid gland region originating from the zygomatic branch of the facial nerve, both of which were removed concurrently. After tumor resection, the dura mater of middle cranial fossa was directly exposed in the nasal sinus in 2 cases, including 1 case accompanied by cerebrospinal fluid leakage which was reconstructed by a free mucosal flap obtained from the middle turbinate, the other case was packed by the autologous fat to protect the dura mater. The operation time was (M(IQR)) 180 (160) minutes (range: 120 to 485 minutes). No complications and deaths were observed. No recurrence was observed in the 10 patients with total tumor resection during a 58 (68) months' (range: 10 to 90 months) follow-up. No obvious change was observed in the facial appearance of all patients during the follow-up. Conclusion: Type D trigeminal schwannoma involving pterygopalatine fossa and infratemporal fossa can be removed safely through purely endoscopic endonasal approach by selecting the appropriate approach according to the size and involvement of the tumor.

OBJECTIVE@#To compare the effect of acupuncture at Huiyin (CV 1) and oral administration of western medication in treatment of chronic severe functional constipation (CSFC).@*METHODS@#A total of 64 patients with CSFC were randomly divided into an acupuncture group (32 cases, 5 cases dropped off) and a western medication group (32 cases, 4 cases dropped off). Both groups were given routine basic treatment. The acupuncture group was treated by directly puncture of 20-30 mm at Huiyin (CV 1), once a day for the first 4 weeks, 5 times a week, once every other day for the next 4 weeks, 3 times a week, totally for 8 weeks. The western medication group was treated with 2 mg prucalopride succinate tablets orally before breakfast every day for 8 weeks. The average number of weekly spontaneous bowel movement (SBM) of the two groups were observed before treatment and 1-8 weeks into treatment. The constipation symptom score before and after treatment, and in follow-up of 1 month after treatment, as well as quality of life [patient assessment of constipation quality of life questionnaire (PAC-QOL) score and the proportion of patients of PAC-QOL score difference before and after treatment≥1] before and after treatment were compared in the two groups. The clinical effects of the two groups were evaluated after treatment and in follow-up.@*RESULTS@#Compared before treatment, the average number of weekly SBM in the two groups was increased 1-8 weeks into treatment (P<0.05). The average number of weekly SBM in the acupuncture group was less than that in the western medication group 1 week into treatment (P<0.05), and the average number of weekly SBM in the observation group was more than that in the western medication group 4-8 weeks into treatment (P<0.05). The scores of constipation symptom after treatment and in follow-up and scores of PAC-QOL after-treatment in the two groups were lower than those before treatment (P<0.05), and those in the acupuncture group were lower than the western medication group (P<0.05). The proportion of patients of PAC-QOL score difference before and after treatment≥1 in the acupuncture group was higher than that in the west medication group (P<0.05). The total effective rates after treatment and in follow-up in the acupuncture group were 81.5% (22/27) and 78.3% (18/23), respectively, which were better than 42.9% (12/28) and 43.5% (10/23) in the western medication group (P<0.05).@*CONCLUSION@#Acupuncture at Huiyin (CV 1) can effectively increase the number of spontaneous defecation in patients with CSFC, reduce constipation symptoms, improve the quality of life, and the effect after treatment and in follow-up is better than oral western medication.

【Objective】 To analyze the implementation and problems in the process of the first policy of serious illness benefits for voluntary blood donors in China, therefore provide reference for other provinces and cities to formulate care policies for voluntary blood donors. 【Methods】 The number of blood donors who received serious illness benefits and the proportion to the total number of blood donors in that year were obtained by Excel, and their basic demographic information, illness and reasons for failing to receive benefits were analyzed. 【Results】 From 2015 to 2019, a total of 198 blood donors applied for serious illness benefits, and 159 received benefits (638 000 yuan), accounting for 0.017% of the total number of voluntary blood donors in Nanjing. The average age of the recipients was 52.66, with the proportion of males (63.5%) higher than that of females (36.5%). 52.8% (the highest proportion) got benefits of 5 000 yuan. 39 applicants failed to obtain serious illness benefits, among which 27 applicants failed during 2017 to 2018 due to unidentifiable funding source. But after Nanjing Blood Donation Regulations clarified the funding sources, the implementation of serious illness benefits policy was continued in 2018. 【Conclusion】 The implementation of serious illness benefits for voluntary blood donors presented the Nanjing municipal government's care for voluntary blood donors. The legalization of this policy is conducive to the continuity and stability of policy implementation. Relevant departments and blood centers should continue to strengthen the policy publicity and make sure the policy is implemented effectively.
ABSTRACT
This study aims to compare the prevalence of sexually transmitted infections (STIs) with semen quality in men from couples with primary and secondary infertility. Semen samples were collected from 133 men who requested fertility evaluation. Seminal tract infection with Ureaplasma spp. (UU), Mycoplasma hominis (MH), Mycoplasma genitalium (MG), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and herpes simplex virus-2 (HSV-2) was assessed by PCR-based diagnostic assays. Among all patients, the prevalence of STIs was higher in men from couples with primary infertility than that in men from couples with secondary infertility (39.7% vs 21.7%, P = 0.03). The prevalence of UU was 28.8% and 13.3% in men from couples with primary and secondary infertility, respectively. Men from couples with primary infertility were more likely to be positive for UU than men from couples with secondary infertility (P = 0.04). Regarding the UU subtype, the prevalence of Ureaplasma urealyticum (Uuu) and Ureaplasma parvum (Uup; including Uup1, Uup3, Uup6, and Uup14) did not differ between the two groups. No associations between the prevalence rates of MH, MG, and CT were found in men from either infertility group. A lower sperm concentration was associated with STI pathogen positivity in men with primary infertility according to the crude model (P = 0.04). The crude and adjusted models showed that semen volume (both P = 0.03) and semen leukocyte count (both P = 0.02) were independently associated with secondary infertility. These findings suggest the importance of classifying the type of infertility during routine diagnosis of seminal tract infections.

Objective To discuss 7Be and a 77.2 keV full-energy peak with short half-life found in the water sample from the 3D water phantom of a proton therapy system. Methods We measured the water sample from the 3D water phantom of a proton therapy system according to Determination of Radionuclides in Water by Gamma Spectrometry (GB/T 16140—2018). Results The activity concentration of 7Be in the water sample was 1.30 × 101 Bq·L−1 on December 24, 2018; 4.3 × 101 Bq·L−1 on March 22, 2019; and 1.41 × 101 Bq·L−1 at the time of sampling on December 19, 2018. On December 24, 2018, the net peak area of the 77.2 keV full-energy peak in the sample was 683 ± 45, and the measurement time was 26123.02 s; on March 22, 2019, the net peak area decreased to the background level of 194 ± 49, and the measurement time was 86400.00 s. Conclusion In the 3D water phantom of the proton therapy system, 7Be can be generated from the spallation reaction between high-energy neutrons and oxygen in water. In addition, we find a full-energy peak at 77.2 keV with short half-life. The activity concentration of 7Be in the water sample is lower than the exemption level, but the activity concentration at sampling may not be the maximum activity concentration in the process of quality control. The inductive radionuclide 7Be produced in the 3D water phantom should be identified and properly evaluated in the assessment of occupational radiation hazards of proton therapy system.
