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:To explore the feasibility of an "ABC" three line perforator locating method in design and harvest of free anterolateral perforator flap of calf.Methods:Between March 2021 and November 2021, 42 patients with 62 wounds on hand and foot were treated in the Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital. The "ABC" three line perforator locating method was applied to determine the location and source of perforating branch before operation and to guide the design and harvest of flap during operation in wound reconstruction. Among the 42 patients, 24 had the injury of single digit, 7 had the injuries with 2 digits, 4 with 3 digits, 1 with 4 digits, 1 of the first web, 1 in the wrist, 2 of the great toe, 1 of second toe and 1 in dorsal foot. The sizes of soft tissue defect were 1.5 cm×2.0 cm-3.0 cm×14.0 cm. The sizes of the flaps were 2.0 cm×2.5 cm-3.5 cm×15.0 cm. All donor sites were sutured directly. In the follow-up, sensations of flaps were evaluated following the sensory function evaluation standard of British Medical Research Council(BMRC), and the recovery of the donor and recipient sites was evaluated by the flap comprehensive evaluation scale. Regular follow-up were scheduled at outpatient clinic.Results:A total of 162 perforators were located before operation. There were 95 perforating branches being explored in the operation, of which 5 patients had 1 extra perforating branch than that located before surgery. Seventy-six perforating branches were found consistent with preoperative localisation, with a coincidence rate of 84.4%(76/90). Sixty-four perforating branches were found consistent with the preoperative source with an accuracy rate of 84.2%(64/76). All the 62 flaps survived without a vascular compromise. Follow-up lasted for 6-10(mean 7.1) months. The colour and texture of the flaps were excellent. The flaps were thin and wear-resistant. The sensory function of the flaps was evaluated at S 1-S 3 by BMRC. Comprehensive evaluation scale of flap was excellent in 38 patients and good in 4 patients. Conclusion:"ABC" three line perforator locating method in design of free anterolateral calf flap is a feasible and an ideal auxiliary method in surgical practice. It combines anatomical knowledge, clinical experience and Doppler ultrasound localisation as well as accurately guides the location and source prediction of perforator before surgery.

This paper explores the interpretation of Jichuan Decoction （济川煎） by tracing its name's origin， exa-mining the original texts of herbs in the decoction within Jingyue's Complete Works（《景岳全书》）， exploring the debate on the sovereign drug of Danggui （Angelica sinensis ［Oliv.］ Diels） and Roucongrong （Cistanche deserticola Y.C. Ma）， and analyzing the historical discussions on the efficacy of the decoction. It is believed that the original meaning of the name Jichuan Decoction （济川煎） refers to its strategy for treating “deficiency constipation”， which can be described as “increasing water to navigating the boat”. Danggui （Angelica sinensis ［Oliv.］ Diels） is considered the sovereign herb for nourishing blood and moistening dryness， while Roucongrong （Cistanche deserticola Y.C. Ma） serves as the minister herb for moistening the intestines and promoting bowel movements. It is concluded by the author that Jichuan Decoction （济川煎） does not primarily focus on warming the kidneys and assisting yang， but rather emphasizes nourishing blood， moistening dryness， and promoting bowel movements. Its main indication is constipation due to deficiency of yin and blood， which is supported by evidence from antiquarian materials.

As the smallest combination unit of Chinese medicinals， herbal pairs serve as the bridge between medicinals and formulas， whose combination theory reflects the basic characteristics of Chinese medicinals combination and the core essence of prescription composition. Simultaneously， as a key combination of medicinals in clinical treatment of diseases， syndromes， and symptoms， herbal pairs are the main form of clinical medication in traditional Chinese medicine （TCM） as well as the characteristic advantage of treating diseases. This article summarized that “mutual complement of medicinals of same or antagonism flavor and nature” theory is the theoretical origin， and efficacy-enhancement and toxicity-attenuation is the core purpose of the combination of herbal pairs. The property theory of Chinese medicinals and the thought of differentiation and treatment are the main basis of the combination of herbal pairs， and pertinence and flexibility are the key points in clinical application. All mentioned above are expected to provide theoretical guidance for the clinical use and modern research of herbal pairs.
