In the past ten years, the clinical application of fecal microbiota transplantation (FMT) in the treatment of intestinal and extraintestinal diseases has attracted much attention. In China, there are more than 300 hospitals that have developed FMT, but the development of FMT is still in its early stage. The clinical practice of FMT needs to form a standardized system, including management of donors and acceptors, preparation of capsules containing certain gut bacteria, evaluation of effectiveness, and study of fecal microbiota and disease. In order to promote the establishment of the standard system of FMT and the healthy development of FMT, this paper expounds the establishment of the standardization of domestic flora transplantation according to the relevant literature, as well as the experience of 10000 cases and 95300 times of FMT in our center.

With the development of global economy and society,the number of patients who suffer from functional gastrointestinal disorders (FGID) and mental illness is growing. In recent years, a substantial amount of high-quality research evidence shows that these two kinds of diseases often coexist, and they are mutually causal, and their common pathophysiology is the abnormal interaction of "bacteria-gut-brain axis". In clinical practice, there are some problems, such as insufficient recognition and attention of both doctors and patients to its clinical manifestations, lack of understanding of pathophysiological mechanism, and lack of overall and integrated views of intervention methods, which may be the main factors of poor curative effect at present. Therefore, according to the global research progress and the author's clinical experience, we put forward a new viewpoint of "gastrointestinal psychiatry", it concluded that clinical intervention strategies needed to include dietary and lifestyle changes as well as multidisciplinary interventions such as probiotics, prebiotic, fecal microbiota transplantation and cognitive psychology. On the basis of gastrointestinal psychiatry, this paper systematically elaborated the diagnosis and treatment of this kind of diseases.

Objective: To summarize and analyze the clinical effect of fecal microbiota transplantation (FMT) combined with nutritional support and psychotherapy in patients with "Tetralogy of Tongji" (comprising chronic gastrointestinal dysfunction, mental and psychological disorders, malnutrition, and endocrine disorders). Methods: A longitudinal study was conducted. The inclusion criteria were as follows: (1) patients were under 70 years of age; (2) patients exhibited chronic gastrointestinal dysfunction (in accordance with the Rome IV diagnostic criteria for irritable bowel syndrome ie. chronic functional constipation, diarrhea, abdominal pain and abdominal distention) with onset occurring more than one year previously; (3) patients exhibited malnutrition (body mass index ≤ 18.5 kg/m²); (4) patients exhibited depression, anxiety, or state as diagnosed by a psychologist using the Hamilton anxiety rating scale (HAMA) and the Hamilton depression scale (HAMD); (5) patients were women of childbearing age with amenorrhea or menstrual disorder with a duration ≥6 months. Patients were excluded if they exhibited gastrointestinal bleeding, short bowel syndrome, radiation-induced intestinal injury, intestinal obstruction or inflammatory bowel disease, recurrent/metastatic tumors, systemic infectious diseases, life-threatening systemic comorbidities, intorlerate to nasojejunal, percutaneous gastrostomy / jejunostomy or FMT. The clinical data of 43 patients at Shanghai Tenth People's Hospital exhibiting the "Tetralogy of Tongji" and who received microflora transplantation combined with nutritional support and psychotherapy from June 2017 to June 2021 was prospectively collected. There were 12 males and 31 females with a mean age of 35.2±16.7 years. All 43 patients had chronic gastrointestinal dysfunction. Of these, 24 patients had depression and 19 had anxiety. There were 26 women of reproductive age, including 13 cases of menstrual disorder and 9 cases of amenorrhea. The treatment intervention was a combination of FMT (microflora solution or microflora capsule), nutritional support (enteral nutrition) and psychological intervention. The following were assessed before treatment and 1, 3, 6 months after treatment: (1) gastrointestinal function was assessed using the gastrointestinal symptoms rating scale (GSRS), where a higher score is indicative of more serious gastrointestinal symptoms, and the gastrointestinal quality of life index (GIQLI), where a higher score is indicative of higher quality of life; (2) psychological status was assessed using HAMA and HAMD scores, where a lower score is indicative of reduced severity of anxiety or depression symptoms, respectively; (3) nutritional status was assessed by measurements of total blood protein, albumin, fibrinogen and prealbumin, as well as measurements of body mass and body mass index (BMI); (4) neuroendocrine function was assessed by measurement of blood levels of cortisol, dopamine and noradrenaline, as well as menstruation in women of reproductive age. Results: The follow-up rates at 1, 3 and 6 months after treatment were 90.7% (39/43), 72.1% (31/43) and 55.8% (24/43), respectively. The total effective rate for chronic gastrointestinal dysfunction was 81.4% (35/43), of which the average GSRS score decreased from 29.35±3.56 before treatment to 18.25±2.56 in the sixth month (P<0.001). The average GIQLI score increased from 56.23±10.34 before treatment to 91.04±20.39 in the sixth month (P<0.001). All patients had malnutrition before treatment. After 6 months, their body weight had increased from 40.61±8.88 kg to 50.45±6.23 kg (P<0.001), and BMI had increased from 15.17±1.87 kg/m² to 19.58±1.42 kg/m² (P<0.001). The average total protein level was 60.99± 5.99 g/L before treatment. After 6 months, this had increased to 64.21±4.23 g/L (F=2.715, P=0.022). The average prealbumin level increased from 150.14±56.04 mg/L before treatment to 258.17±86.94 mg/L after 6 months (F=15.124, P<0.001). In this study, 24 patients with depression/depressed state were included. After treatment, the average HAMD score in these patients decreased from 22.79±6.63 before treatment to 9.92±7.24 after 6 months (P<0.001). There were 19 patients with anxiety disorder/anxiety state. After treatment, the average HAMA score in these patients decreased from 17.15±4.34 before treatment to 7.73±4.10 after 6 months (P<0.001). Observing the endocrine efficacy of 26 women of childbearing age, it was found that the effective rate of this treatment on endocrine regulation was 69.2% (18/26). Although there was no significant change in blood cortisol levels after 6 months, average blood dopamine levels decreased from 32.91±10.65 nmol/L before treatment to 13.02±5.58 nmol/L after 6 months (P<0.001). Average blood norepinephrine levels decreased from 49.75±15.23 ng/L before treatment to 19.21±9.58 ng/L after 6 months (P<0.001). Conclusion: The strategy of FMT combined with nutritional support and psychological intervention is effective in improving the symptoms of the "Tetralogy of Tongji".

Objective: To explore and establish the preparation system of human intestinal fluid transplantation (HIFT) and HIFT capsule, and to preliminarily apply it to clinic. Methods: Strict standards for donor screening and management were established. The nasojejunal tube was catheterized into the distal jejunum, and then it was connected with an improved disposable sterile negative pressure collection device for the collection of human intestinal fluid. After that, it was prepared into capsules by filtering, adding 10% glycerin protectant and freeze-drying method. The amount of living bacteria was used as the standard of therapeutic dose. The living bacteria amount in fluid is ≥ 5.0×10⁸ /mL and the living bacteria proportion is ≥ 83%; the living bacteria amount in powder is ≥ 2.0×10⁶ /g and the living bacteria proportion is ≥ 81%; The observational indicators included: (1) the basic information of the donor, the amount of living bacteria in the HIF and powder. (2) Preliminary analysis of the treatment for ASD, which combined HIFT capsule with standard FMT capsule, from February to December 2021 (Clinical trial Registration Number: ChiCTR2100043929). Evaluation criteria: Trypan blue staining method was used to detect the living bacteria amount in fluid and powder. The Autism Behavior Checklist (ABC) and Childhood Autism Rating Scale (CARS) were used to evaluate the efficacy. Results: Compared with the parent donor, the standard donor was younger [(25.4±0.9) y vs. (30.7±3.2) y, t=-19.097, P=0.001] and had a lower body mass index [(19.7±0.5) kg/m² vs. (20.8±1.3) kg/m², t=-8.726, P=0.001], more in the living bacteria amount in powder [(7.47±1.52)×10⁶/g vs. (5.03±1.38)×10⁶/g, t=11.331, P=0.031], Chao index (205.4±6.8 vs. 194.2±7.2, t=10.415, P=0.001), and Shannon index (3.25±0.14 vs 2.72±0.27, t=19.465, P=0.001). The differences were statistically significant (all P<0.05). However, there were no significant differences in gender, drainage volume and total number of bacterial liquid colonies between the two groups (all P>0.05). Both the standard donor and the parent donor met the donor screening criteria, and the preparation fluid and powder met the treatment criteria. Eight patients received the treatment of HIFT combined with fecal microbiota transplantation (FMT). Preliminary statistical results showed that HIFT combined with FMT improved ABC and CARS at the 1st, 2nd, 3rd and 4th months. The differences were statistically significant (all P<0.05). No severe adverse reaction occurred. Conclusion: Based on the previous research on FMT preparation system and the clinical technology in our center, this study developed a high standard HIFT preparation system, and explored the clinical study of HIFT combined with FMT, in order to provide an innovative therapy for the treatment of diseases.

OBJECTIVE: To analyze the efficacy of children with B-cell acute lymphoblastic leukemia (B-ALL) without prognostic fusion genes treated by CCLG-ALL 2008, and investigate the related factors affecting the recurrence of the patients. METHODS: B-ALL patients without prognostic fusion genes treated by the protocol of CCLG-ALL 2008 in our hospital from March 2008 to December 2012 were retrospectively analyzed. Follow-up time was ended in August 31, 2019. The median follow-up time was 92 months (range 0-136 months). Kaplan-Meier was used to detect the RFS, and COX multivariate regression analysis was employed to identify the independent factors affecting the recurrence of the patients. RESULTS: There were 140 males and 99 females enrolled in this study. The ratio of male to female was 1.41∶1. The median age was 4.4 years old and the median number of WBC at initial stage was 4.98×10⁹/L. There were 77 cases relapsed during the observation while 162 without relapsed, 16 cases lost to follow-up and 72 cases died. The recurrence and mortality rate was 32.22% and 30.1%, respectively, in which 45 cases died of recurrence (62.5% of the total deaths). Univariate analysis showed that the age≥6 years old, WBC >100×10⁹/L, the bone marrow blasts on day 15≥25%, the bone marrow minimal residual disease (MRD) at week 12 >10^-4, and the higher risk were the main factors affecting the recurrence of the patients (P<0.05). Multivariate COX regression analysis showed that age≥6 years old, WBC >100×10⁹/L, bone marrow MRD >10^-4 at the 12th week were the independent risk factors affecting recurrence of the patients. CONCLUSION Age, initial WBC, and bone marrow MRD at the 12th week were correlated with recurrence in children with B-ALL without prognostic fusion genes, which can be used as prognostic indices of recurrence risk in clinical.

OBJECTIVE: To investigate the incidence rate of infectious diseases during hospitalization in late preterm infants in Beijing, China, as well as the risk factors for infectious diseases and the effect of breastfeeding on the development of infectious diseases. METHODS: Related data were collected from the late preterm infants who were hospitalized in the neonatal wards of 25 hospitals in Beijing, China, from October 23, 2015 to October 30, 2017. According to the feeding pattern, they were divided into a breastfeeding group and a formula feeding group. The two groups were compared in terms of general status and incidence rate of infectious diseases. A multivariate logistic regression analysis was used to investigate the risk factors for infectious diseases. RESULTS: A total of 1 576 late preterm infants were enrolled, with 153 infants in the breastfeeding group and 1 423 in the formula feeding group. Of all infants, 484 (30.71%) experienced infectious diseases. The breastfeeding group had a significantly lower incidence rate of infectious diseases than the formula feeding group (22.88% vs 31.55%, CONCLUSIONS Breastfeeding can significantly reduce the incidence of infectious diseases and is a protective factor against infectious diseases in late preterm infants. Breastfeeding should therefore be actively promoted for late preterm infants during hospitalization.

The study was designed to investigate the effect of IMPDH1 gene polymorphism on the pharmacodynamics of mycophenolic acid in the renal transplant patients. 315 patients with renal transplantation were treated with triple immunotherapy (mycophenolic acid + tacrolimus + prednisone). The Agena MassARRAY assay was used to detect the IMPDH1 genotypes in patients above. The plasma drug concentration of mycophenolic acid (MPA) and its main metabolite mycophenolic acid glucuronide (MPAG) was detected by high performance liquid chromatography (HPLC). The correlation between IMPDH1 gene polymorphism (rs10954183, rs12536006, rs13242340, rs2278293, rs2288549) and rejection and postoperative infection in renal transplant recipients were analyzed by SPSS 21 software. The result showed that IMPDH1 rs2288549 GG is a risk factor for acute rejection after renal transplantation (P<0.05), and IMPDH1 rs2278293 CT is a risk factor for infection after renal transplantation (P<0.05). Above all, IMPDH1 rs2288549 is an important factor of acute rejection after renal transplantation, IMPDH1 rs2278293 is an important factor affecting the emergence of infection after renal transplantation. The SNPs may help to optimize clinical medication to reduce the incidence of adverse reaction.

The study found that the presence of intestinal microbiota is not only important for the metabolism of essential nutrients in the body, but also plays a key role in the development of the body′s immune system in recent years. Partial microbiota, through natural selection and co-evolution with the host, forms symbiotic relationships with host microbes that are inseparable from host physiology in mice. Symbiotic flora affects the formation of the body′s immune system by affecting innate and adaptive immunity and the development of various regulatory mechanisms. The destruction of the microbial ecosystem in the intestine can lead to the occurrence of many diseases,especially those related to the immune system. Peripheral immune organs always receive a number of immune cells colonized by antigen stimulation. So,the intestinal flora plays an important role in maintaining the function of immune cells. This article will investigates the effects of mouse-related intestinal flora on peripheral immune organ function.

OBJECTIVETo investigate the prenatal diagnosis of a case of SEA-HPFH deletion combined with beta-thalassemia in a Chinese family.

METHODSGap-PCR and RDB methods were applied to test the genotype for the family.

RESULTSMother showed a SEA-HPFH thalasemia trait phenotype, while her genotype was heterozygote for SEA-HPFH deletion; father showed a beta-thalassemia trait phenotype, while his genotype was heterozygote for IVS-II-654 mutation; the genotype of fetus was normal in these tests.

CONCLUSIONRegular thalassemia genes and deletion beta-thalassemia genes can be used in prenatal diagnosis of the case at risk for compound heterozygotes of SEA-HPFH deletion and beta-thalassemia.

OBJECTIVETo investigate whether sodium valproate (VPA) directly regulates the activity of Ankyrin G(AnkG) promoter in vitro.

METHODSThe mouse AnkG promoter sequence was identified by comparing both human and mouse AnkG promoter sequences. The promoter was amplified from C57BL/6 mouse genome DNA and cloned into pGL3 Luciferase reporter vector. The Luciferase activity was detected in N2a and 293T cells and then treated with 0,0.5, and 1 mmol/L VPA for 12 h. The transcription activity of AnkG promoter in cells and the activity of VPA-treated Luciferase reporter vector in cells were detected using dual Luciferase reporter assay.

RESULTSThe AnkG promoter clone and its expression vector were successfully established, as confirmed by enzyme digestion and sequencing. The AnkG promoter showed high transcription activity in both N2a and 293T cells. The Luciferase activity was significantly induced following 0.5 mmol/L VPA treatment in both N2a and 293T cells. CONCLUSIONS VPA can up-regulate the AnkG expression via directly increasing its transcription activity. Thus, the in vivo AnkG expression may be directly regulated by the VPA at transcriptional level.
