Objective:To observe the clinical efficacy of Shanghai-style tuina method based on syndrome differentiation in treating infantile diarrhea. Methods:Sixty patients were randomly divided into an observation group and a control group, 30 cases in each group. The patients in the observation group were treated by Shanghai-style tuina method based on syndrome differentiation, while the patients in the control group were treated by conventional Shanghai-style tuina method, once per day, continuous 5 d for a treatment course. The efficacy was evaluated according to the score of the quantization table for symptoms differentiation in infantile diarrhea after one course. Results:During the treatment, two cases in the control group dropped out. After treatment, the scores were significantly decreased in both groups and the intra-group differences were statistically significant (both P<0.01), indicating the two treatment methods were effective with infantile diarrhea. In the efficacies of traditional Chinese medicine (TCM) syndrome, the cured and markedly effective rate in the observation group was significantly higher than that in the control group (P<0.05), suggesting that Shanghai-style tuina method based on syndrome differentiation was more effective than conventional Shanghai-style tuina method. Conclusion:Conventional Shanghai-style tuina method is characterized by fixed acupoints, remembering easily and operating conveniently. It has a significant effect in treating children with diarrhea, and is worthy of clinical promotion and popularization. However, Shanghai-style tuina method based on syndromes differentiation requires the solid theoretical foundation and rich clinical experience of TCM. And because Shanghai-style tuina method based on syndromes differentiation is applied under the guidance of syndrome differentiation and TCM theory, it can improve the clinical efficacy.

A promising genetic marker, sag5b, was cloned and expressed and the difference of the genes between highly virulent strain (RH) and less virulent strain(Prugniaud) of Toxoplasma gondii was compared. The PCR-generated product of sag5b was subcloned into T easy vector and plasmid pET28a consecutively. The fusion expression was induced by IPTG and identified by SDS-PAGE and Western blotting. The immunoreactivity of recombinant SAG5B was identical to that of native SAG5B on the membrane of tachyzoites of RH strain. The brains of mice infected with Prugniaud strain of T. gondii were homogenated. Sag1 was successully cloned by PCR from both RH strain tachyzoites and the homogenized brain tissues of mice infected with low virulent strain of Prugniaud,whereas sag5b was only detected in RH strain but not in Prugniaud strain, indicating that sag5b could be used as a genetic marker for differentiation of strain virulence. Expression and vaccination of the virulence-associated gene into mice failed to induce obvious protective immunity against the challenge of RH strain.

This article was to elucidate that the needling depth is closely related to the meridian qi, disease location, disease nature and needled area based on the records of needling depth in Nei Jing (Canon of Internal Medicine). Moreover, different depths will produce different therapeutic efficacies;meanwhile, improper depth may lead to grave consequences.

Objective To observe the effect of pre-intervention with electroacupuncture at Neiguan (PC 6) plusα2-adrenoceptor (α2AR) agonist on peri-operative heart rate variability (HRV).Method A total of 120 patients going to receive lower limb orthopedic surgery were randomized into four groups by using the random number table, namely a control group (group A), an electroacupuncture group (group C), anα2AR agonist group (group D) and an electroacupuncture plus medication group (group N), 30 cases in each group. The indicators of heart rate variability (HRV), including the standard deviation of normal-to-normal (N-N) intervals (SDNN), standard deviation of the average of N-N intervals (SDANN), root mean square successive differences (rMSSD), percentage of adjacent N-N intervals>50 ms apart (pNN50), low-frequency power (LF), high-frequency power (HF), LF/HF and total power (TP) were recorded 1 d prior and 1 d after the operation; meanwhile, the mean arterial pressure (MAP) and heart rate (HR) were recorded before incubation (T0), right after incubation (T1), 5 min after incubation (T2), right afterextubation (T3), 5 min after extubation (T4), 60 min after extubation (T5), and 180 after extubation (T6).Result In group N, the HR and MAP at the other time points were insignificantly different from those at T0 (P>0.05); in group A, the HR and MAP at T1-T6 were significantly different from those at T0 (P<0.05); in group C and D, the HR and MAP at T1-T4 were significantly different from those at T0 (P<0.05); the HR and MAP in group N were significantly lower than those in group A at T1-T6 (P<0.05) and were significantly lower than those in group C and D at T1-T4 (P<0.05); the HR and MAP in group C and D were significantly lower than those in group A at T5 and T6 (P<0.05). In group A, the LF, HF, LF/HF and TP 1 d after the operation were significantly increased compared to those 1 d prior to the operation (P<0.05); in group A and D, the SDNN, SDANN, rMSSD, and pNN501 d after the operation were significantly lower than those 1 d prior to the operation (P<0.05); the LF, HF, LF/HF, and TP in group C, D and N were significantly lower than those in group A 1 d after the operation (P<0.05); the SDNN, SDANN, rMSSD, and pNN50 in group C and N were significantly higher than those in group A and D 1 d after the operation (P<0.05). Conclusion Pre-intervention electroacupuncture plusα2AR agonist can improve the balance of cardiac sympathetic and vagus nerves, and better maintain the peri-operative hemodynamic stability.

Objective: To investigate the health effects of air pollution on elementary school students with the indicator of absenteeism caused by respiratory symptoms and diseases, and to provide a reference for improving their physical health. Methods: Absenteeism, air pollutants, and meteorological data during Sep. 2015 to Jun. 2017 in Pudong, Shanghai were collected. Generalized additive model was used to estimate the effects of air pollution on students’ absenteeism caused by respiratory symptom and diseases, time trends, day of week and meteorological factors were controlled. Results: Totally 47 723 person-days of elementary school students’ absenteeism caused by respiratory symptoms and diseases were recorded during Sep.2015 to Jun. 2016 in Pudong, Shanghai, and the absenteeism rate was 0.07%. The PM2.5 concentration on lag0 and SO2 concentration on lag2 showed the most significant effects, the elementary school students’ absenteeism raised for 1.43% (95%CI=0.25%~2.62%)and 6.79% (95%CI=0.25%~13.32%) respectively with every 10 μg/m3 increment of PM2.5 and SO2. Conclusion Air pollution in Pudong new area have made a influence on the elementary school student’s respiratory symptoms and absenteeism, and the prevention work of air pollution should be strenghthened.

Objective:To compared the changes of macular microvascular architecture in early stage familial exudative vitreoretinopathy (FEVR) patients with inner retinal layer (IRL) persistence and without IRL persistence.Methods:A retrospective clinical study. From 2017 to 2022, 94 patients with stage 1 FEVR with or without IRL residue and 45 age- and sex-matched healthy volunteers with 45 eyes (normal control group) who were confirmed by ophthalmology examination in Hangzhou Hospital of Optometry Affiliated to Wenzhou Medical University and Zhejiang Provincial People's Hospital were included in the study. According to whether there was IRL residue, the patients were divided into IRL group and non-IRL group, with 22 patients (22 eyes) and 72 patients (72 eyes), respectively. Best corrected visual acuity (BCVA) and optical coherence tomography angiography (OCTA) were performed in all eyes. Superficial vessel density (SCP) and deep vessel density (DCP) of whole image, fovea and parafovea, the area and perimeter of fovea avascular area (FAZ), A-circularity index (AI, perimeter/standard circle perimeter with equal area) and vessel density around the 300 μm width of the FAZ (FD), central macular thickness (CMT) on macular 3 mm × 3 mm scan on OCTA were measured.Results:SCP and DCP of whole image ( F=10.774, 4.583) and parafovea ( F=10.433, 3.912), CMT ( F=171.940) in IRL group and non-IRL group on macular 3 mm × 3 mm scan on OCTA were significantly lower than that in normal persons ( P<0.05). There were significant differences among three groups of the area of FAZ ( F=4.315), AI ( F=3.413), FD-300 ( F=13.592) ( P<0.05). BCVA were worst in IRL group ( P<0.05). Conclusions:Blood flow density decreased in macular area of FEVR patients. CMT is significantly thicker than normal population. The FAZ area of the foveal IRL residual eyes is small and irregular, with worse BCVA and lower macular blood density.

OBJECTIVETo evaluate the clinical efficacy of YANG's pricking-cupping therapy for knee osteoar thritis (KOA). Methods This was a multi-center randomized parallel controlled trial. One hundred and seventy one patients with KOA were randomly allocated to a pricking-cupping group (89 cases) and a conventional acu puncture group (82 cases). Neixiyan (EX-LE 4), Dubi (ST 35) and ashi points were selected in the two groups. Patients in the pricking-cupping group were treated with YANG's pricking-cupping therapy; the seven-star needles were used to perform pricking at acupoints, then cupping was used until slight bleeding was observed. Patients in the conventional acupuncture group were treated with semi-standardized filiform needle therapy. The treatment was given for 4 weeks (from a minimum of 5 times to a maximum of 10 times). The follow-up visit was 4 weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the visual analogue scale (VAS) were adopted for the efficacy assessments.

RESULTSThe pain score, stiffness score, physical function score and total score of WOMAC were all reduced after 4-week treatment and during follow-up visit in the two groups (all P<0. 0001). Except that the difference of stiffness score between the two groups was not significant after 4-week treatment (P>0. 05), each score and total score of WOMAC in the pricking-cupping group were lower than those in the conventional acupuncture group after 4-week treatment and during follow-up visit (P<0. 0001, P<0. 01). After 2-week treatment, 4-week treatment and during follow-up visit, the VAS was all reduced compared with that before treatment (all P<0. 0001) ; with the increase of the treatment, the reducing trend of VAS was more significant (P<0. 0001). The scores of VAS in the pricking-cupping group were lower than those in the conventional acupuncture group after 4-week treatment and during follow-up visit (P < 0. 01, P <0. 0001). CONCLUSION The YANG's pricking-cupping and conventional acupuncture therapy can both significantly improve knee joint pain and function in patients with KOA, which are relatively safe. The pricking cupping therapy is superior to conventional acupuncture with the identical selection of acupoints.

It was a cross-sectional study. Six myocardial infarction patients with non-obstructive coronary artery disease (MINOCA group) admitted to Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from July 2021 to August 2022 were enrolled in the study and 78 healthy subjects were selected as control group. The patients and healthy controls were selected with 1∶1 propensity score matching according to age, gender, body mass index, occupation and marriage status; and 5 study subjects of each group were finally enrolled in the study. The general clinical data and magnetocardiographic (MCG) results were collected from the hospital′s electronic medical record system. Compared with control group, MINOCA group showed abnormal QR rotation, discrete changes in positive and negative magnetic poles in TT segment, and disordered current direction. The analysis of MCG data revealed 35 parameters with statistically significant difference between the two groups, involving TT interval, QRS complex, RS interval and QR interval. This study explored the magnetocardiographic characteristics of MINOCA, which suggest that MCG may be conducive for diagnosis of MINOCA in the future.

Objective To establish a novel convenient loop?mediated isothermal amplification(LAMP)method with the unique genes coding Plasmodium helical interspersed sub?telomeric superfamily(PHIST)for the rapid molecular diagnosis of P. falciparum. Methods The unique genes coding PHIST with high expression mRNA profile during the ring form or schizont period of P. falciparum were screened and selected from the PlasmoDB database. The LAMP primers of targeted genes were de?signed by the online software(PrimerExplorer V4). The LAMP assay was executed by the color?displaying method with SYBR Green. The dried blood spots of P. falciparum from clinical isolates were collected and the genomic DNA(gDNA)was extracted. For evaluation of sensitivity,the gDNA was diluted to four gradients(10?1,10?2,10?3,and 10?4). For assessment of specificity, the gDNA(s)of P. vivax,P. yoelii,Taenia saginata,and Schistosoma japonicum were also extracted. Results Totally,61 P. falciparum unique genes coding PHIST were found. The PF3D7_1372300 with high expression value during the ring form and PF3D7_1401600 with high expression value during the schizont period were selected for LAMP assay. The lowest detectable lim?its of PF3D7_1372300 and PF3D7_1401600 were 130.5 parasite/μl and 1 305.3 parasite/μl,respectively. Specific tests showed the amplified products of P. falciparum was positive and all the others including P. vivax,P. yoelii,T. saginata,and S. japoni?cum were negative. Conclusions The established LAMP method with PF3D7_1372300 gene is sensitive,specific,simple and useful. It can be applied to the field investigation and clinical diagnosis for falciparum malaria.
