ABSTRACT
【Objective】 To investigate the efficacy of low-frequency neuromuscular electrical stimulation in the treatment of penile hypersensitive premature ejaculation. 【Methods】 A total of 66 patients treated during Nov.2021 and Aug.2022 were randomly divided into electrical stimulation group (n=22), local anesthesia group (n=21), and combined therapy group (n=23). The electrical stimulation group received low-frequency neuromuscular electrical stimulation, 5 times a week;the local anesthesia group used compound lidocaine cream 30 minutes before sexual intercourse;the combined therapy group received both treatments. After 3-month treatment, the latency of dorsal nerve somatosensory evoked potential (DNSEP), glans penis somatosensory evoked potential (GPSEP), intravaginal ejaculation latency time (IELT), premature ejaculation diagnostic tool score (PEDT), and spouse sexual satisfaction score were collected. 【Results】 After treatment, IELT, PEDT, spouse’s sexual life satisfaction score, DNSEP and GPSEP of the three groups were significantly improved (P0.05). 【Conclusion】 Low-frequency neuromuscular electrical stimulation is effective in the treatment of penile hypersensitive premature ejaculation, and the combination of local anesthetics is more effective, which is worthy of clinical application and promotion.
ABSTRACT
Objective:To investigate the predictors of the efficacy of extracorporeal shock wave lithotripsy (ESWL) in the treatment of ureteral calculi, and to evaluate the predictive value of the maximum ureteral wall thickness (UWT) in the treatment of ureteral calculi with ESWL.Methods:The clinical data of 138 patients with ureteral calculi treated with ESWL in the Second People's Hospital of Hefei from January 2020 to December 2020 were retrospectively analyzed. There were 91 males and 47 females. The age was (50.9±14.8) years old. The body mass index was (25.3±3.6) kg/m 2. The stones of 73 cases were located on the left side and 65 cases were on the right side. 70 cases had upper ureteral stones, 18 cases had middle ureteral stones, and 50 cases had lower ureteral stones. The median length of the stone was 8.5 (7.5, 10.5) mm. The CT value of the stone was 509 (343, 783) HU. The anteroposterior diameter of the renal pelvis was 12.0 (10.1, 16.0) mm, and UWT was (2.8 ± 0.8) mm. All patients underwent urinary non-contrast CT before lithotripsy, and the UWT of the stone bed was measured on the CT images. According to the stone removal situation 2 weeks after the operation, the patients were divided into a successful lithotripsy group and a failed lithotripsy group. Univariate analysis was used to compare the differences of various indicators between the two groups, and multivariate logistic regression was used to analyze the independent predictors of ESWL in the treatment of ureteral calculi for the indicators. The receiver operating characteristic (ROC) curve was used to calculate the area under the curve (AUC) of each independent predictor, and the cut-off value, sensitivity and specificity were analyzed. Results:All operations were successfully completed, and the success rate of the first-stage lithotripsy was 71.7% (99/138). The results of univariate analysis showed that the stone length diameter, stone CT value, anteroposterior diameter of renal pelvis, stone skin distance, and UWT were significantly different between the successful lithotripsy group and the failure group ( P<0.05). There was no significant difference in age, gender, body mass index, stone side and stone location ( P>0.05). The results of multivariate logistic analysis showed that stone length ( OR=1.393, P=0.015), stone CT value ( OR=1.002, P=0.043) and UWT ( OR=17.997, P<0.001) were all for the efficacy of ESWL in the treatment of ureteral stones. The ROC curve was used to compare the three independent predictors. The area under the UWT curve was the largest (AUC=0.898, P<0.001), followed by the length of the stone (AUC=0.744, P<0.001), and the CT value of the stone (AUC=0.672, P= 0.002). The cut-off value for UWT was 3.19 mm, which had a sensitivity of 91.9% and a specificity of 71.8% for predicting the success of ESWL lithotripsy. When dividing the patients into thin wall group (UWT ≤3.19 mm) and thick wall group (UWT>3.19 mm) according to the cut-off value, the success rates of one-stage lithotripsy in the two groups were 89.2% (91 / 102) and 22.2% (8/36), respectively ( P<0.05). Conclusions:UWT, calculus length and calculus CT value are independent predictors of the efficacy of ESWL in the treatment of ureteral calculi, and UWT has the best predictive value. When UWT≤3.19 mm, the success rate of ESWL in the treatment of ureteral calculi is higher.
ABSTRACT
Objective:To investigate the diagnostic value of bronchial arteriography CT (BA-ACT) combined with bronchoscopy (BS) in bronchial Dieulafoy′s disease (BDD), and the role of bronchial artery embolization (BAE) in the treatment of BDD.Methods:Retrospective analysis was made on the clinical data of 5 patients suspected of being BDD treated by BS in Guangzhou First People′s Hospital or Guangzhou Thoracic Hospital from January 2008 to January 2018 due to hemoptysis. Bronchial arteriography (BAG) and BA-ACT were performed during the operation of interventional embolization. BAG rotary acquisition data were post-processed according to BS findings, and BA-ACT reconstruction images of the diseased bronchi and bronchial arteries were obtained. BS reexamination and clinical follow-up observation were carried out after embolization to analyze the effect of embolization.Results:There were one BDD lesion for the five patients respectively, and the BAG lacked characteristic manifestations. Bronchoscopy revealed BDD foci to present as papillary (case 1-case 3), nodular (case 4), or lirellate (case 5) subbronchial submucosal protrusion lesions. On the BA-ACT reconstruction plot, the BDD lesions of papillary, nodular and carination manifested correspondingly as a bronchial artery branches locally " pointed arch" shaped (cases 1-case 4) or " bead-like" (case 5) fold and protruding toward the bronchial lumen. The BDD lesions of the cases 1-case 4 retraction and disappearance after one BAE were observed by BS examination, and no hemoptysis recurrence during the follow-up period (54-91 months). The ridge like BDD lesion of the case 5 remained unchanged after BAE, and hemoptysis recurred at 71 months after the first BAE; the uncollapsed foci were supplied by two collateral vessels that confirmed by second BAG and BA-ACT, and no hemoptysis for 71 months followed up after second BAE.Conclusions:BA-ACT combined with BS enables a locative and qualitative diagnosis of BDD, and BAE is a very effective treatment method for BDD.
ABSTRACT
Objective:To study the clinical value of artificial dermis combined with autologous thin skin graft in the repair of burn scar contracture in joints.Methods:A total of 52 patients with burn scar contractures were enrolled in the No.5 Hospital of Baoding from July 2015 to April 2018. According to different methods of repair, 26 cases were used in each group. The observation group was treated with artificial dermis combined with autologous thin skin graft. The control group was treated with medium-thickness skin grafting. The survival rate of autologous skin was compared between the two groups. The tissue of artificial dermal polyester fiber was taken and HE staining was performed to observe the pathological changes. The Vancouver skin scar assessment score (VSS), functional activity, infection rate, wound healing time, and VSS score after healing of the donor site were compared between the two groups.Results:The survival rate of autologous skin in the observation group (92.31%) was not significantly different from that in the control group (84.62%) ( P>0.05). Compared with preoperative, the VSS scores at 3, 6 months and 1 year after operation in both groups were decreased ( P<0.05). The VSS scores of the observation group were lower than those of the control group at 3, 6 months and 1 year ( P<0.05). The excellent rate of functional activity in the observation group (100.00%) was higher than that of the control group (76.92%) ( P<0.05); There was no significant difference in the infection rate (3.85% vs 7.69%) and healing time of skin grafting area between the two groups ( P>0.05). The healing time of donor site was shorter than that of the control group ( P<0.05). The VSS score of the donor site was lower than that of the control group ( P<0.05). Conclusions:Artificial dermis combined with autologous thin skin graft can be used in patients with burn scar contracture in joints, which can improve the scarring of skin grafting area and donor site, shorten the healing time of donor site and improve the function of burn scar contracture joint.

ABSTRACT
Objective:s To evaluate the impacts of prior surgical scores(PSS) on the clinical efficacy and perioperative safety of cytoreductive surgery(CRS) and hyperthermic intraperitoneal chemotherapy(HIPEC) for pseudomyxoma peritonei(PMP).Methods:From the comprehensive PMP database, we collect the cases treated for the first time by CRS+ HIPEC, to form this study cohort. The clinicopathological features, PSS, CRS+ HIPEC details, overall survival(OS), and serious adverse events(SAEs) are systematically analyzed, to study the correlations between PSS and OS or SAEs.Results:335 PMP cases received standardized CRS+ HIPEC in this study. The median OS is 58.2 months for PSS-0 patients, 63.7 months for PSS-1, and 55.4 months for PSS-2/3, with no statistically significant differences in OS among the different PSS groups(χ 2=0.499, P=0.779). Subgroup analysis by pathologic types also found no statistically significant differences among the different PSS groups. Moreover, no significantly statistical differences are observed in overall SAEs(χ 2=0.625, P=0.722), CRS-related SAEs(χ 2=0.267, P=0.901), and non-CRS-related SAEs(χ 2=0.677, P=0.715), among the different PSS groups. Conclusions:PSS does not pose significant impacts on the efficacy and safety of CRS+ HIPEC for PMP patients at experienced treatment center.
ABSTRACT
Objective:To investigate the prognostic significance of introtumoral and peritumoral lymphangiogenesis in colorectal cancer.Methods:Lymphangiogenesis of 120 colorectal cancer specimens, as measured by lymphatic vessel density (LVD), were examined by immunostaining for podoplanin, a lymphatic specific marker. The mean number of lymphatic vessel in three hotspots was calculated in intratumoral and peritumoral areas as intratumoral LVD (LVDit) and peritumoral LVD (LVDpt) respectively. The association of LVDit and LVDpt with the clinicopathologic findings and prognosis were investigated.Results:Compared to the peritumoral lymphatics, the intratumoral lymphatics were small, collapsed and irregular. LVDit was positively correlated with tumor size ( t=2.673, P=0.009), tumor histologic grade ( t=-2.296, P=0.023), and overall survival (χ 2=4.386, P=0.036). LVDpt was associated with lymph node metastasis ( t=-4.053, P<0.001), tumor stage ( t=4.740, P=0.004) and overall survival (χ 2=5.806, P=0.016). Conclusions:LVDpt played an important role in lymph node metastasis, while LVDit was more correlated with tumor growth and histopathologic differentiation. Both LVDs contribute to colorectal cancer progression and predict poor prognosis.

ABSTRACT
Objective To evaluate the adjuvant activities of cyclic guanosine monophosphate-adenosine monophosphate ( cGAMP) in enhancing humoral and cellular responses against Helicobacter pylori ( H. pylori) . Methods BALB/c mice were immunized with the protein antigens including UreA, UreB and NapA of H. pylori in combination with cGAMP as the adjuvant on 0 d and 14 d by subcutaneous administra-tion. Then, the serum-specific antibody responses were evaluated by ELISA. Flow cytometry ( FCM) and enzyme-linked immunospot assay ( ELISpot) were used to detect the cellular immune responses occurred in spleen and mesenteric lymph nodes (MLN). Results Subcutaneous administration of protein antigens of H. pylori together with cGAMP induced strong humoral and cellular immune responses in BALB/c mice. The levels of serum-specific IgG antibodies induced by adding cGAMP as the adjuvant were significantly higher than those by immunizing with antigens alone. The levels of splenic IFN-γ-producing lymphocytes in re-sponse to H. pylori antigens and cGAMP immunization were significantly higher than those in the correspond-ing groups without using cGAMP. Conclusion By using cGAMP as an adjuvant, H. pylori antigens could elicit significantly stronger humoral and cellular immune responses in mice than those induced by the anti-gens only. As a stable small molecular compound with strong adjuvant activity, cGAMP has the potential to be used for the development of H. pylori vaccine.

ABSTRACT
Objective To explore the risk factors for patients with massive hemoptysis in tuberculosis and to provide a strategy for clinical treatment for tuberculosis massive hemoptysis (TMH). Methods Chi-square test and multivariate logistics analysis were applied to analyze the medical data of 241 cases of TMH. Results Chi-squared test showed that eleven factors were found to be significantly correlated with TMH. Longer disease course (≥3 months), lung lesions range ≥ 3 lung fields, pulmonary tuberculosis cavity, a higher smoking index (≥400 cigarettes per year) and clinical treatment were risk factors for TMH. Patients aged 45 years or older accompanied with bronchiectasia, pulmonary fungal infection, diabetes or hepatopathy had higher probabilities of developing massive hemoptysis. Multivariate analysis showed lung lesions range over 3 lung fields (OR = 2.447,P = 0.015), pulmonary tuberculosis cavity (OR = 2.486, P = 0.004), bronchial asthma (OR =3.192,P = 0.002), pulmonary fungal infection (OR = 3.896, P = 0.005) and hepatopathy (OR = 3.101, P =0.006) were final risk factors for TMH. Conclusion Multiple factors contributed to patients with massive hemoptysis in tuberculosis. Lung lesions range over 3 lung fields, pulmonary tuberculous cavities, bronchial asthma, lung fungal infection and hepatopathy might be the independent risk factors for TMH.

Objective To evaluate the clinical outcomes of the hybrid technique of posterior osteotomy with short segmental fusion and dual growing rod technique for severe rigid congenital scoliosis.Methods Seven patients (2males,5 females) undergoing this hybrid technique for severe rigid congenital scoliosis in our hospital from 2006 to 2011 were retrospectively studied.The average age was 5.9 years (range,2-10).The Risser sign of all the patients was 0.The follow-up time was 59.4 months (range,36-83 months).The patients' charts were reviewed.The analysis included age at initial surgery and the latest follow-up,number and frequency of lengthening,and complications.Radiographic evaluation included measured changes in scoliosis Cobb angle,thoracic kyphosis,lumbar lordosis,trunk shift,length of T1-S1 and instrumentation.Results All patients were treated with posterior osteotomy with short segmental fusion and dual growing rod technique.There were 48 total surgeries,41 of which were lengthening procedures,for 7 patients.The average lengthening was 5.9 per patient.The mean scoliosis improved from 81.4° to 40.1 ° after initial surgery and was 41.1 ° at the final follow-up.The average T1-S1 length was of 1.12 cm per year.The Campbell's space available for lung ratio increased from 0.87 to 0.97.Conclusion Osteotomy with short fusion could help to improve the correction of the growing rod and eliminate the large asymmetric growth potential around the apex,with little influence to the length of the spine.Dual growing rod technique could maintain correction achieved at initial surgery while allowing spinal growth to continue.However,this technique is relatively more aggressive and technique demanding.And the patients need numbers of surgeries.
ABSTRACT
Objective To find humoral protein markers to develop new experimental diagnostic methods for tuberculous pleurisy. Methods Proteomes of 7 d and 14 d culture filtrate of Mycobacterium tuberculosis growing in Middlebrook 7H9, serum and pleural effusion from five patients with tuberculous pleurisy were detected by surface-enhanced laser desorptionionization time-of-flight massspectrometry (SELDI-TOF-MS). And the data were analyzed with descriptive statistics method to observed the protein components all owned by three kinds of proteome. Results From protein species, proteins of all culture filtrate were far more than that of pleural effusion and serum while proteins of pleural effusion in four cases were more than that of serum. The kinds of common proteins between culture filtrate and pleural effusion, between culture filtrate and serum, between serum and pleural effusion, among culture filtrate and pleural effusion and serum were different. But the protein of relative molecular mass of 2 660 depending on the ratio of mass to charge existed in all samples of culture filtrate, pleural effusion and serum. Conclusion The protein of relative molecular mass of 2 660 possess the latent quality as a specific humoral protein marker for tuberculous pleurisy. But it is essential that must be further confirmed among large samples.
