Objective: To evaluate the efficacy and safety of fecal microbiota transplantation (FMT) in the treatment of autism spectrum disorder (ASD). Methods: A longitudinal study was conducted. Clinical data from ASD patients with gastrointestinal symptoms and who underwent FMT in the Tenth People's Hospital affiliated to Tongji University or Jinling Hospital between May 2012 to May 2021 were retrospectively collected. Scores derived from the autism behavior checklist (ABC), the childhood autism rating scale (CARS), the Bristol stool form scale (BSFS), and the gastrointestinal symptom rating scale (GSRS) were analyzed at baseline and at the 1st, 3rd, 6th, 12th, 24th, 36th, 48th and 60th month after FMT. Records of any adverse reactions were collected. Generalized estimating equations were used for analysis of data on time points before and after FMT. Results: A total of 328 patients met the inclusion criteria for this study. Their mean age was 6.1±3.4 years old. The cohort included 271 boys and 57 girls. The percentage of patients remaining in the study for post-treatment follow-up at the 1st, 3rd, 12th, 24th, 36th, 48th and 60th month were as follows: 303 (92.4%), 284 (86.7%), 213 (64.9%), 190 (57.9%), 143 (43.6%), 79 (24.1%), 46 (14.0%), 31 (9.5%). After FMT, the average ABC score was significantly improved in the first 36 months and remained improved at the 48th month. However, the average score was not significantly different from baseline by the 60th month (1st-36th month, P<0.001; 48th month, P=0.008; 60th month, P=0.108). The average CARS score improved significantly during the first 48 months and remained improved at the 60th month (1st-48th month, P<0.001; 60th month, P=0.010). The average BSFS score was also significantly improved in the first 36 months (with an accompanying stool morphology that resembled type 4). This improvement was maintained at the 48th month. However, the average score was similar to baseline at the 60th month (1st-36th month, P<0.001; 48th month, P=0.008; 60th month, P=0.109). The average GSRS score was significantly improved during the first 24 months, but not afterwards (1st-24th month, P<0.001; 36th month, P=0.209; 48th month, P=0.996; 60th month, P=0.668). The adverse events recorded during treatment included abdominal distension in 21 cases (6.4%), nausea in 14 cases (4.3%), vomiting in 9 cases (2.7%), abdominal pain in 15 cases (4.6%), diarrhea in 18 cases (5.5%), fever in 13 cases (4.0%), and excitement in 24 cases (7.3%). All adverse reactions were mild to moderate and improved immediately after suspension of FMT or on treatment of symptoms. No serious adverse reactions occurred. Conclusion: FMT has satisfactory long-term efficacy and safety for the treatment of ASD with gastrointestinal symptoms.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

Infection is an important cause of higher mortality in patients with hematological diseases than healthy people, and fever is often the only indication of the disease.Clostridium perfringens(C.perfringens)is a grampositive anaerobic bacillus of the Clostridiumgenus, it belongs to the normal flora of the intestinal tract and is not pathogenic in normal condition.However, when intestinal flora is imbalanced due to low hypoimmunity of human body or influenced by such factors as diet, medicine, environment and other factors, it can enter the blood and cause bacteremia.At present, it has never been reported that bacteremia was caused by C.perfringens in patients with malignant hematological diseases accompanied by neutropenia, this article reported the diagnosis and treatment of C. perfringens bloodstream in one patient with malignant hematopathy, so as to provide basis for diagnosis and treatment of the disease.

Objectives: This study aimed to observe the change of arachidonic acid-induced platelet aggregation rate (AA-Ag) and short-term adverse reactions after taking 50 or 100 mg/d aspirin(enteric-coated sustained-release formulation) or 100 mg/d aspirin (enteric-coated aspirin tablet)in the elderly Chinese population (aged 60 years or older). Methods: A total of 1 194 participants aged 60 or older, who should be recommended to take aspirin therapy due to medical reasons, were recruited and randomly assigned into three groups to receive enteric-coated sustained-release aspirin tablet (50 mg, once daily, group A), or 100 mg, once daily (group B) or enteric-coated aspirin tablet 100 mg once daily (group C), respectively. AA-Ag was measured after (14±3)days of aspirin treatment. Adverse events and bleeding events were recorded during the (28±3)days of follow-up. Results: The AA-Ag in group A (n=347), B (n=338) and C (n=332) post 14-day aspirin therapy were 6.65 (4.03,10.84)%, 5.89(3.22,10.03) % and 6.00(3.68,10.09) %, respectively (P>0.05). During the 28 days follow-up, the adverse events rate of group A (n=388), B (n=387) and C (n=385) was 3.87%,3.36%, and 7.95%, and the mild bleeding events rate was 3.09%, 2.33%, and 6.23%, respectively. Adverse events rate and mild bleeding events rate were significantly higher in group C than in group A and B (P<0.05). Conclusions: Compared with 100 mg-dose aspirin, 50 mg-dose aspirin achieves similar anti-platelet aggregation effect in this elderly Chinese population. The short-term adverse events and mild bleeding risk of aspirin with enteric-coated sustained-release formulation were fewer than that of enteric-coated formulation.

To explore the flavor and meridian tropism classification of Callianthemum taipaicum by principal components analysis(PCA) and partial least square analysis(PLS). Meanwhile,to establish a high performance liquid chromatography-tandem mass spectrometry(HPLC-ESI-MS) method for the simultaneous determination of 55 active components from 13 kinds of Ranunculaceae of Chinese traditional herbs. Samples were separated on HPLC system by Agilent 5 TC-C₁₈（2）（4.6 mm×250 mm，5 μm）column and eluted with acetonitrile and 0.1% formic acid at the flow rate of 0.6 mL·min⁻¹. The data were performed by HPLC-ESI-MS with multiple reaction monitoring（MRM）scanning mode under positive and negative ion modes and quantified by external standards. The data from 13 Ranunculaceae herbs were analyzed by the PLS-tree and cooman's prediction of PCA and PLS to evaluate the similarities and differences of C. taipaicum in flavor and meridian tropism. The results showed that calibration curves of 55 components all showed good linearity, >0.99,with good precision, repeatability and stability. After compared to other 12 herbs,PCA and PLS results revealed that the C. taipaicum belonged to lung and bladder meridians while its flavor attributive to pungent,warm in nature. In conclusion,the analysis approach of chemometric calculation combined with multi-components quantification is suitable for the classification of meridian tropism and flavor of Chinese traditional medicine,which can be used for alternative research of rare herbs.

OBJECTIVETo investigate the blood test patterns for blood donors after nucleic acid detection in blood center.

METHODSThe collected blood samples after voluntary blood donors first were detected by conventional ELISA, then 31981 negative samples were detected via HBV/HCV/HIV combined nucleic acid test of 6 mixed samples(22716 cases) or single samples(9265 cases) by means of Roche cobas s201 instrument. The combined detection method as follows: the blood samples were assayed by conventional nucleic acid test of 6 mixed samples, at same time, 6 mixed samples were treated with polyethylene glycol precipitation method to concentrate the virus, then the nucleic acid test of blood samples was performed; the single detection method as follows: firstly the conventional nucleic acid test of single sample was performed, then the positive reactive samples after re-examination were 6-fold diluted to simulate the nucleic acid test of 6-mixed samples. The positive rate of positive samples detected by combined nucleic acid test, positive samples detected by nucleic acid test of mixed virus concentration and positive samples detected by single nucleic acid test was statistically analyzed. In addition, for HBVpersons the serological test yet should be performed.

RESULTSIn 22 716 samples detected by nucleic acid test of 6 mixed samples (MP-6-NAT) , 9 cases were HBV(0.40‰, 9/22716); at same time, the detection of same samples by nucleic acid test of mixed sample virus concentration showed 29 cases of HBV(1.28‰, 29/22716). In 9265 samples detected by single nucleic acid test(ID-NAT) 12 cases showed HBV(1.30‰, 12/9265), meanwhile the detection of these 12 samples with HBVby 6-fold dilution for virus concentration found only 4 samples with HBV. In serological qualified samples, ID-NAT unqualified rate was 1.28‰, which was higher than that of MP-6-NAT(0.4‰) (χ=8.11, P<0.05); but there was no statistical difference between unqualified rate of ID-NAT and MP-6-NAT(1.3‰ vs 1.28‰)(χ=0.00, P>0.05). In 41 samples with HBsAgHBV DNAdetected by ELISA, 36 samples were confirmed to be occult HBV infective(OBI) by HBsAb, HBcAb test of ELISA; out of these 41 samples, 33 samples showed HBcAb(91.66% of OBI), 5 might be HBV "window period" infective, moreover the HCV RNA and HIV RNA positive samples were not found.

CONCLUSIONTo avoid the missdiagnosis of donors with low level of virus, the nucleic acid test must be carried out after virus concentration of mixed samples when the blood test pattern of donors is nucleic acid test of mixed samples, otherwise the single nucleic acid test must be performed to obtain more high detected rate of virus nucleic acid. The HBcAb serologic test and physical examination of donors before blood donation must be enhanced on basis of serological test of HBsAg; for high risk people, the persuading no blood donation is simplest pattern.

OBJECTIVETo investigate the effect of premature rupture of the membrane (PROM) on neonatal complications in premature infants.

METHODSThe registration information of 7684 preterm infants with gestational age <37 weeks were collected from the cooperative units in the task group between January 1, 2014 to December 31, 2014. Specially trained personnel from each cooperative units filled in the unified form in a standardized format to record the gender, gestational age, birth weight, PROM, placental abruption, antenatal corticosteroid, Apgar score, amniotic fluid pollution, and complications of the infants. The data were analyzed comparatively between the cases with PROM and those without (control).

RESULTSThe preterm mortality rate was significantly lower but the incidences of ICH, NEC, ROP and BPD were significantly higher in PROM group than in the control group (P<0.05). The 95% confidence interval of the OR value was <1 for mortality, and was >1 for ICH, NEC, ROP and BPD. After adjustment for gestational age, birth weight, gender, mode of delivery, placental abruption, placenta previa, prenatal hormones, gestational diabetes mellitus (GDM), gestational period hypertension and 5-min Apgar score <7, the incidences of NEC, ROP and BPD were significantly different between the two groups (P<0.05) with 95% confidence interval of OR value >1, but the mortality rate and incidence of ICH were not significantly different between the two groups (P>0.05).

CONCLUSIONPROM is a risk factor for NEC, ROP and BPD in preterm infants, and adequate intervention of PROM can reduce the incidences of such complications as NEC, ROP and BPD in the infants.

To investigate the effect of schisantherin A on liver sinusoid endothelial cell function and angiogenesis. Different dosages (0-40 μmol•L⁻¹) of schisantherin A were incubated 24 h with SK-HEP-1 cells, and the toxicity of SK-HEP-1 cells was assayed by MTT method. The proliferation of SK-HEP-1 cells were induced by the vascular endothelial growth factor (VEGF), with receptor tyrosine kinase inhibitor sorafenib as the control, at the same time, set up the control group, 2, 20 μmol•L⁻¹ schisantherin A were incubated with SK-HEP-1 cells, cell proliferation was analyzed by EdU DNA cell proliferation kit. Fluorescence probe method was used to assay the intracellular NO levels and NOS activity. Tube formation was observed using cell migration and a matrigel tube formation assay. Rat aortic ring assay was performed to observe the sprouting vessels from aortic ring. The fluorescence vessels, the number of functional blood vessels, and intersegmental vessel changes of transgenic zebrafish were also observed. Compared with control group, the proliferation of SK-HEP-1 cells induced by VEGF increased and and the level of NO and NOS activity induced; compared with model group, 2, 20 μmol•L⁻¹ schisantherin A and sorafenib inhibited the proliferation of SK-Hep-1 cells induced by VEGF, and reduced the level of NO and NOS activity. At the dosage of 20 μmol•L⁻¹, schisantherin A attenuated the migration and tube formation of SK-HEP-1 cells induced by VEGF, and also inhibition the formation of rat aortic rings and intersegmental vessel changes of transgenic zebrafish, and significantly reduce the number of vessels in zebrafish. Schisantherin A has potential effects on function of endothelial cell proliferation and angiogenesis.

OBJECTIVETo study the value of amino-terminal pro-brain natriuretic peptide (NT-proBNP) in predicting symptomatic patent ductus arteriosus (sPDA) in preterm infants.

METHODSPreterm infants born at a gestational age (GA) of ≤ 32 weeks and diagnosed with patent ductus arteriosus (PDA) by echocardiography within 48 hours after birth between June 2014 and April 2015 were selected as subjects. Their clinical manifestations were observed, and serum NT-proBNP levels were measured and echocardiography was performed at 3 and 5 days after birth. The infants were divided into sPDA group and asymptomatic PDA (asPDA) group based on their clinical manifestations and the results of echocardiography. The correlations between serum NT-proBNP level and echocardiographic indices were analyzed. Serum NT-proBNP levels were compared between the two groups. The receiver operator characteristic (ROC) curve was applied to determine the sensitivity and specificity of serum NT-proBNP in the prediction of sPDA.

RESULTSA total of 69 preterm infants were enrolled in this study, with 13 infants in the sPDA group and 56 infants in the asPDA group. Serum NT-proBNP level was positively correlated with the diameter of the arterial duct (r=0.856; P<0.05)and the ratio of left atrial diameter to aortic root diameter (LA/AO) (r=0.713; P<0.05). At 3 and 5 days after birth, the serum NT-proBNP levels in the sPDA group were significantly higher than those in the asPDA group (P<0.05). The area under the ROC curve (AUC) for the prediction of sPDA by NT-proBNP levels at 3 days after birth was 0.949 (95% CI: 0.892-1.000; P<0.001), with a cut-off value of 27 035 pg/mL (sensitivity: 92.3%; specificity: 94.6%); the AUC for the prediction of sPDA by NT-proBNP levels at 5 days after birth was 0.924 (95% CI: 0.848-1.000; P<0.001), with a cut-off value of 6 411 pg/mL (sensitivity: 92.3%; specificity: 92.9%).

CONCLUSIONSNT-proBNP may be a quantitative index for shunt volume. The measurement of serum NT-proBNP levels on 3 and 5 days after birth may be useful to predict sPDA in preterm infants.

The overall survival of patients with cervical cancer has improved due to detection at an early stage and availability of comprehensive treatments in China. As patients' lives prolonged, it is important to understand their health-related quality of life (QoL) during and after treatment. We used the EQ-5D questionnaire to assess QoL of 194 patients with cervical lesions at Sichuan University West China Second Hospital between May 2010 and January 2011. Patients were surveyed before primary treatment and at 1, 3, and 6 months after primary treatment. Results showed a consistent decline in EQ-5D scores in the spectrum of cervical lesions at each time point after treatment (all P < 0.05). For patients with precursor lesions, there was an increasing trend along the timeline of treatment (P < 0.01). For patients with early-stage cervical cancer, EQ-5D scores declined in the first month (P = 0.01) and gradually increased to higher levels at 6 months post-treatment than those before treatment (P < 0.01). EQ-5D scores followed a similar trend in patients with advanced cervical cancer (P = 0.04), though they did not statistically rebound after 6 months (0.84 ± 0.19 vs. 0.86 ± 0.11, P = 0.62). Regarding advanced cervical cancer, EQ-5D scores for women above 40 years of age appeared to recover more rapidly and reached higher levels than those for women below 40 years (P = 0.03). Caution and extra care are recommended in the early period of cervical cancer treatment given the slight deterioration in the QoL, and in particular, for younger cervical cancer patients. Our study implies that health care providers may need to improve the health-related QoL of cervical cancer patients.
