Objective To assess the clinical effectiveness and safety of relinqing pharmaceutical preparations for the treatment of uncomplicated urinary tract infection(UTI). Methods The genitourinary infection, urinary tract infection, pyelonephritis, cystitis, stranguria and urethritis were used as key words to search at CNKI,VIP,SinoMed,PubMed,Wan Fang and Cochrane Library Databases up to April 2015. Data of randomised controlled trials (RCTs) comparing treatments using relinqing were included in this study. The quality of the literature was evaluated by the method of Cochrane handbook 5.1.0. Data extraction was carried out independently by two authors. RevMan 5.2 software was used for Meta-analysis. Results Five RCTs were included that involved a total of 471 uncomplicated UTIs. Analysis of four studies showed a higher rates of effectiveness for uncomplicated UTI in the treatment with relinqing plus antibiotics than those of antibiotics alone [RR and 95%CI:1.15 (1.08-1.23), P<0.001]. Analysis of two studies showed a higher rates of bacterial clearance for uncomplicated UTI in the treatment with relinqing plus antibiotics than those of antibiotics alone [RR and 95% CI: 4.04 (1.78-9.16)]. Conclusion Data from five small studies suggest that relinqing as an independent intervention or in conjunction with antibiotics may be beneficial for treating uncomplicated UTIs. However, the small number and poor quality of the included studies meant that it is not possible to formulate robust conclusion on the use of relinqing for uncomplicated UTI either alone or as an adjunct to antibiotics.

Thirty-four cases out of 830 children with diarrhea were confirmed to be positive of fecal cryptosporidial oocysts with IFA technique and monoclonal antibodies in a period of 2 years. These 34 cases could be diagnosed as cryptosporidial enteritis. Their age ranged from 4 months to 7. 6 years with an average of 2. 5?1. 7 years. The stool was frothy and watery in appearance. High incidence occurred form June to September. Determination of PHA skin test, LBT and serum Ig was performed on 27 patients before, during and after the treatment of Astragalus membranaceus Bunge and Sophora flavescens Ait ( 2 traditional Chinese herb medicines). It was found that diarrhea lasted 10. 9?7. 1 days and oocyst shedding lasted 21. 5? 12. 3 days. Before treatment) PHA skin test showed an erythema of 7. 9?2. 4 mm in diameter, and LBT value was 48. 7%?10. 1% and they returned to normal after treatment.It is suggested that hot safrain-methylene blue stain and modified acid-fast stain of the stool be performed in those children with diarrhea of unknown etiology as a routine screening for cryptosporidial oocysts. The 2 Chinese herb medicines may have a repelling effect on the parasites and be. helpful to the cell immunity of the patients. Asymptomatic carriers of cry-tosporidial oocysts may be the source of infection.

Objective To compare the short-term and long-term therapeutic effects of oral rehydration salts,metoprolol or midodrine hydrochloride in children with postural tachycardia syndrome (POTS).Methods Two hundred and forty-four children with POTS diagnosed in the First Hospital Peking University of from Dec.2004 to Jan.2013 were followed up in clinics or by telephone.They were divided into oral rehydration salt group (n =75),metoprolol group (n =66) and midodrine hydrochloride group (n =103).The patients were followed up for 3 ～ 100 months.Results After 3 months of treatment,the symptom scoring of the three groups was improved greatly as compared with the baseline data.Therapeutic effect of midodrine hydrochloride group was significantly superior to metoprolol group and oral rehydration salt group (x2 =8.750,P =0.013).One hundred and forty-two out of 244 children were followed up and their head-up tilt test(HUT)was repeated.The HR increment of children in 3 groups became smaller as compared with before treatment (P ＜ 0.05).After follow-up,the symptom scoring was improved greatly as compared with the baseline scoring (P ＜ 0.05).The short-term effect of midodrine hydrochloride group was significantly better than that of metoprolol group or oral rehydration salt group (x2 =8.750,P =0.013).The Kaplan-Meier curves showed that the long-term effect of midodrine hydrochloride group was significantly superior to metoprolol group and oral rehydration salt group (89.3％vs 78.8％,P =0.033;89.3％ vs 76.0％,P =0.002).Conclusion Oral rehydration salts,midodrine hydrochloride or metoprolol were all effective for POTS in children.And the short-term and long-term effect of midodrine hydrochloride might be superior to metoprolol and oral rehydration salts.

Objective To evaluate the effects of different reconstruction algorithms on image quality for Philips GEMINI PET/CT. Methods Jaszczak phantom were scanned on the GEMINI PET/CT system, and the raw data were reconstructed using filtered-back projection with Hanning filter (FBP-Hanning), filtered-back projection with Butterworth filter (FBP-Butterworth), ordered subset expectation maximization (OSEM), row-action maximum likelihood algorithm (RAMLA) and three-dimensional row-action maximum likelihood algorithm (3D-RAMLA), respectively. The resolution, uniformity, contrast of images and the time of different reconstruction algorithms were compared. Results The reconstruction time was 180 s, 130 s, 120 s, 85 s and 80 s for 3D-RAMLA, RAMLA, OSEM, FBP-Hanning and FBP-Butterworth respectively in phantom studies. The smallest rods with diameter of 4.8 mm of the phantom could be observed for FBP- Butterworth and 6.4 mm for other algorithms in case of high counts. The image contrast of 3D-RAMLA were better than that other algorithms, and the image uniformity of 3D-RAMLA and RAMLA were better than those of other algorithms. The resolution, uniformity and contrast of images with all algorithms decreasd in case of low counts, and the image quality of FBP-Butterworth was not good enough for clinical studies. Conclusion Image quality is variable with different reconstruction algorithms. For clinical PET imaging, it is necessary to choose proper algorithms.

Traditional Chinese medicine (TCM) has a long history in treating infectious diseases, and the form of intervention varies with different medical conditions and disease types. "The battle field of Chinese doctor for anti-epidemic" was formed in fighting against severe acute respiratory syndrome (SARS) epidemics in China, and from the battle, valuable experiences of using TCM for prevention and treatment had been obtained. During responding to coronavirus disease 2019 (COVID-19) epidemics, we followed the principle of keeping summary and perfection while treament. And a whole process of TCM pattern or a model was organized, including early prevention in communities, cluster intervention in isolated places, comprehensive intervention in mobile cabin hospitals, centralized treatment in designated hospitals and rehabilitation support in rehabilitation posts. Thus, the innovation of whole process of TCM intervention was involved in the "trench warfare" strategy and platform system for prevention and treatment of new infectious COVID-19 epidemics. At different stages or conditions, different TCMs were used to play advantageous roles to solve various problems and elevate the effects of prevention and treatment of the disease. The construction of TCM mobile cabin hospitals was an innovation of organization form that might offset the constraints in technology and scale of simple community isolation or simple hospital treatment, exploring a new way for TCM to cope with public health emergencies.

Objective To investigate the efficacy of SPECT/CT in detecting parathyroid lesions in chronic kidney disease (CKD) with secondary hyperparathyroidism (sHPT) patients.Methods Within 2 weeks before parathyroidectomy (PTX),52 patients of CKD with sHPT underwent 99Tcm-sestamibi (99Tcm-MIBI) dual-phase planar and delayed SPECT/CT scintigraphy.Taking surgical pathology as the golden standards,the sensitivity,specificity and accuracy of dual-phase planar,SPECT,CT and SPECT/CT were calculated and compared.Results Totally 172 lesions were detected in surgical operation,including 13 parathyroidomas (PM),26 adenomatoid hyperplasias (AH) and 133 diffuse parathyroid hyperplasias (PH).The sensitivity of 99Tcm-MIBI dual-phase planar,SPECT,CT and SPECT/CT was 55.81％ (96/172),70.35％ (121/172),79.65％ (137/172) and 81.40％ (140/172),respectively,while the specificity was 92.05％(81/88),90.91％ (80/88),76.14％ (67/88),93.18％ (82/88),the accuracy was 68.08％ (177/260),77.31％ (201/260),78.46％ (204/260) and 85.38％ (222/260),respectively.The sensitivity of SPECT/CT was superior to that of SPECT (x9 =17.053,P＜0.001) and 99Tcm-MIBI dual-phase planar (x2 =44.000,P＜0.001).SPECT/CT was superior to CT (x2 =10.316,P =0.001) for specificity,and superior to CT (x2 =13.136,P＜0.001),SPECT (x2 =14.815,P＜0.001) or 99Tcm-MIBI dual-phase planar (x2=39.706,P＜0.001) for accuracy.Conclusion SPECT/CT fusion imaging is better in localization of parathyroid lesions of CKD with sHPT patients than 99Tcm-MIBI dual-phase planar,SPECT or CT imaging alone.

Objective: Randomized controlled trials (RCTs) of Chinese patent medicines and classic traditional Chinese medicine prescriptions were systematically reviewed from both Chinese and English journals published in 2023. A preliminary summary and evaluation were conducted on the generation and translation of clinical evidence for these treatments. This analysis aims to inform future research on clinical efficacy evaluation and guide the rational application of evidence. Methods: RCTs of Chinese patent medicines and classic traditional Chinese prescriptions published in 2023 were comprehensively retrieved from the Artificial Intelligence Clinical Evidence Database for Chinese Patent Medicine (AICED-CPM), with supplementary searches conducted in China National Knowledge Infrastructure (CNKI), Wanfang Data, Chinese Science and Technology Journal Database (VIP), Chinese Biomedical Literature Database (SinoMed), Cochrane Library, PubMed, Embase, and Web of Science. The study characteristics and methodological quality of these RCTs were systematically analyzed and evaluated. Results: A total of 1 443 RCTs of Chinese patent medicines were included, comprising 1 399 Chinese articles and 44 English articles. Additionally, 334 RCTs of classic traditional Chinese medicine prescriptions were found, with 331 published in Chinese and 3 in English. 196 567 participants were included, covering 585 types of Chinese patent medicines (487 oral, 61 injectable, and 37 topical) and 179 classic traditional Chinese medicine prescriptions. The involved studies encompassed 22 types of diseases, with research primarily focusing on diseases of the circulatory system, the respiratory system, and the genitourinary system. The sample sizes ranged from 18 to 3 777 participants, and most studies were conducted at a single center. Methodologically, the implementation of allocation concealment and blinding remained insufficiently emphasized. Conclusion Overall, compared with 2022, both the number of RCT publications and their methodological quality have improved in 2023, with heightened attention to research on diseases of the genitourinary system. However, quality control and standardized management in the design and implementation processes still require enhancement to produce more high-quality clinical evidence and accelerate the translation and application of this evidence.

Objective:To explore the distribution characteristics of the perforators of the oblique branch of the lateral circumflex femoral artery, and to report the clinical effect of the anterolateral thigh flap pedicled with the oblique branch in repairing the wounds of the extremities.Methods:The clinical data of the patients with anterolateral thigh flap pedicled with oblique branch of lateral circumflex femoral artery in Suzhou Ruihua Orthopaedic Hospital from December 2020 to April 2021 were analyzed retrospectively. High frequency color Doppler ultrasound was used to detect the large perforators of the oblique branch of the lateral circumflex femoral artery near the midpoint of the line between the anterior superior iliac spine and the lateral margin of the patella. With reference to the location of the perforators, according to the size and shape of the defect in the recipient area, the anterolateral thigh flap pedicled with oblique branch was designed and dissected to repair the wound. During the operation, the distance between the emitting point of the main oblique branch, the skin entry point of the perforators and the anterior superior iliac spine was measured with a steel ruler, the diameter of the perforators was measured with a microscale, and the number of perforators was counted. The survival and complications of the flap were observed and followed up after operation. In the last follow-up, the comprehensive evaluation scale was used to evaluate the repair effect: 90 to 100 points is excellent, 75 to 89 points is good, 60 to 74 points is average, and less than 60 points is poor.Results:A total of 84 patients were included, including 62 males and 22 females, aged from 14 to 82 years (mean 46.9 years), including 32 cases of hand wounds, 6 cases of forearm wounds, 3 cases of upper arm wounds, 10 cases of calves and 33 cases of foot and ankle wounds. The wound area was 6 cm × 4 cm-20 cm × 45 cm. A total of 88 flaps were removed in 84 patients (skin flaps on both thighs were removed in 4 patients). The size of the skin flap of 88 thighs was 7 cm × 5 cm-37 cm × 11 cm, of which 85 sides of 82 cases survived completely. One case of diabetes had complete necrosis 1 month after operation, and 1 case of 34 cm had necrosis of the distal end of 3 cm × 3 cm skin flap. Necrotic skin flaps were repaired with skin grafting. Four patients developed arterial crisis within 24 hours after operation, and those flaps survived after surgical exploration. All donor areas healed. During the follow-up of 6 to 9 months, the shape of the recipient area was normal in all patients, and there was no deep tissue infection such as osteomyelitis. The color and texture of all flaps were good. The sensation returned to S1-S2 after operation. The skin flap comprehensive evaluation scale was used to evaluate the repair effect. The patients’ score ranged from 73 to 94 points, with an average of 88.1 points. Including 33 excellent cases, 46 good cases and 5 average cases, the excellent and good rate was 94.0%(79/84). A total of 215 perforators were marked with 88 flaps before operation, and 208 perforators were found during the operation(the diameter of the perforators was 0.4-1.5 mm), of which 130 were sent out by oblique branches. There were perforators of the oblique branch in all flaps, with an average of 1.5 on each side, including 84(64.6%) septocutaneous perforators and 46(35.4%) musculocutaneous perforators. Most of the oblique branches originate from the lateral circumflex femoral artery, which runs in the intermuscular septum between the rectus femoris and the intermediate femoris muscle. It is divided into deep branches and superficial branches at the middle and upper 1/3 junction of the line between the anterior superior iliac spine and the lateral margin of the patella. The skin perforators of the oblique branch of the lateral circumflex femoral artery is mostly sent out from the superficial branch, and there are 118 perforators located at the midpoint and proximal end of the line between the anterior superior iliac spine and the lateral margin of the patella, accounting for 90.8% (118/130), reaching a peak at 0.4 (there are 37 perforators).Conclusion:The oblique branch of the lateral circumflex femoral artery is relatively constant, and most of the perforators are located near the midpoint of the line between the anterior superior iliac spine and the lateral margin of the patella, and the proportion of septocutaneous perforator is high. The distribution of perforator is regular, the blood supply is reliable, the application mode is flexible, and the donor site position is more concealed while the blood supply of the flap is secured.

Objective:To investigate the curative effects of the superficial peroneal artery perforator flap carrying two and more homologous perforators in repairing hand and foot wounds.Methods:A retrospective observational study was conducted. From January to September 2021, 23 patients with hand and foot wounds combined with bone or tendon exposure who met the inclusion criteria were admitted to Suzhou Ruihua Orthopaedic Hospital, including 16 males and 7 females, aged 23 to 68 years. After expansion of the wound, the wound area was 3.0 cm×2.0 cm to 11.0 cm×4.0 cm. All the wounds were repaired with the superficial peroneal artery perforator flap carrying two and more homologous perforators. The area of the resected flap was 4.0 cm×2.0 cm to 12.0 cm×5.0 cm. All the wounds in donor areas were sutured directly. During the operation, the resection of the flap, the number and caliber of carried perforators, the caliber of superficial peroneal artery, the length of vascular pedicle, and the number of accompanying veins of the superficial peroneal artery were recorded. The survival of the flap, the occurrence of complications, and the wound healing in the donor area were observed after operation. The recovery of the donor and recipient areas was followed up. At the last follow-up, the comprehensive evaluation scale was used to evaluate the curative effect of flap repair, and the sensory grading scale was used to evaluate the sensory function of the recipient area.Results:Totally 24 flaps were successfully resected in surgical operations, carrying 56 superficial peroneal artery perforators in total, with the caliber of perforators of 0.20-0.70 mm. The calibers of all perforators carried by 7 flaps were smaller than 0.40 mm. Nineteen flaps carried 2 perforators each, 3 flaps carried 3 perforators each, 1 flap carried 4 perforators, and 1 flap carried 5 perforators. During the operation, the superficial peroneal artery was resected with a caliber of 0.40-1.50 mm, the vascular pedicle was 2-6 cm in length, and each superficial peroneal artery had two accompanying veins. After operation, all the flaps survived smoothly, no vascular crisis or distal necrosis occurred, and the wounds healed well in the donor area. During the follow-up of 6 to 10 months after operation, the color, texture, and elasticity of the recipient area were good. Among them, 6 recipient areas were thinned and reshaped because of bloating. There was only linear scar and no obvious scar hyperplasia or pigmentation in the donor area, without significant change in sensory or motor function. At the last follow-up, the curative effect evaluation of flap repair was excellent in 22 flaps and good in 2 flaps, and the sensory function evaluation of the recipient area was grade S 3 in 1 area and grade S 2 in 23 areas. Conclusions:The superficial peroneal artery perforator flap with two and more homologous perforators has sufficient and reliable blood supply and is effective in repairing hand and foot wounds. It provides an ideal solution for the clinical problem in which the original operation scheme is abandoned due to the existence of only multiple slender perforators of caliber smaller than 0.40 mm, and only a single perforator in the operative field that cannot satisfy the needs of the flap blood supply and recipient area.
