Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

OBJECTIVE:
To observe the effect of acupuncture combined with infantile tuina on intestinal flora and its efficacy in children with tic disorders (TD), and to explore its mechanism.
METHODS:
A total of 15 children with TD were recruited as an observation group and 10 healthy children as a healthy control group. Regulating spleen and stomach acupuncture combined with infantile tuina were received in the observation group. First, acupuncture was applied to Zhongwan (CV 12), Tianshu (ST 25), Guanyuan (CV 4), Hegu (LI 4), Zusanli (ST 36), etc., and then abdominal massage and other tuina techniques were applied, once a day, 6 times a week, 2 weeks as a course of treatment, a total of 2 courses of treatment were required. No intervention was given in the healthy control group. In the observation group, Yale global tic severity scale (YGTSS) score and TCM syndrome score were compared before treatment and after 1 and 2 courses of treatment. 16S rRNA sequencing technology was used to detect the intestinal flora in the healthy control group and before and after treatment in the observation group.
RESULTS:
After 1 and 2 courses of treatment, the scores of YGTSS and TCM syndrome in the observation group were lower than those before treatment (P<0.01, P<0.05). Compared with the healthy control group, the number of operational taxonomic units (OTU) and indexes of Chao1, Sobs, Ace and Shannon were decreased in the observation group before treatment (P<0.05, P<0.01). Compared with before treatment, the number of OTU and indexes of Chao1, Sobs, Ace and Shannon were increased in the observation group after treatment (P<0.01, P<0.05). Compared with the healthy control group, the relative abundance of Firmicutes in the observation group before treatment was decreased (P<0.001), while the relative abundance of Bacteroidetes, Bacteroides and Erysipelatoclostridium was increased (P<0.001, P<0.05). Compared with before treatment, the relative abundance of Bacteroidetes in the observation group was decreased (P<0.001) after treatment, while the relative abundance of Actinobacteria, Bifidobacterium and Atopobium was increased (P<0.05, P<0.01).
CONCLUSION
Acupuncture combined with infantile tuina based on the principle of regulating spleen and stomach could effectively improve TD symptoms in children, which may be related to regulating the diversity of intestinal flora, increasing beneficial bacteria, maintaining intestinal microecological balance, and playing a role in improving neurological disorders.

Objective To analyze the genetic subtypes of human immunodeficiency virus (HIV) and the prevalence of pretreatment drug resistance in the newly reported HIV-infected men in Guangxi. Methods The stratified random sampling method was employed to select the newly reported HIV-infected men aged≥50 years old in 14 cities of Guangxi from January to June in 2020.The pol gene of HIV-1 was amplified by nested reverse transcription polymerase chain reaction and then sequenced.The mutation sites associated with drug resistance and the degree of drug resistance were then analyzed. Results A total of 615 HIV-infected men were included in the study.The genetic subtypes of CRF01_AE,CRF07_BC,and CRF08_BC accounted for 57.4% (353/615),17.1% (105/615),and 22.4% (138/615),respectively.The mutations associated with the resistance to nucleoside reverse transcriptase inhibitors (NRTI),non-nucleoside reverse transcriptase inhibitors (NNRTI),and protease inhibitors occurred in 8 (1.3%),18 (2.9%),and 0 patients,respectively.M184V (0.7%) and K103N (1.8%) were the mutations with the highest occurrence rates for the resistance to NRTIs and NNRTIs,respectively.Twenty-two (3.6%) patients were resistant to at least one type of inhibitors.Specifically,4 (0.7%),14 (2.3%),4 (0.7%),and 0 patients were resistant to NRTIs,NNRTIs,both NRTIs and NNRTIs,and protease inhibitors,respectively.The pretreatment resistance to NNRTIs had much higher frequency than that to NRTIs (2.9% vs.1.3%;χ2=3.929,P=0.047).The prevalence of pretreatment resistance to lamivudine,zidovudine,tenofovir,abacavir,rilpivirine,efavirenz,nevirapine,and lopinavir/ritonavir was 0.8%, 0.3%, 0.7%, 1.0%, 1.3%, 2.8%, 2.9%, and 0, respectively. Conclusions CRF01_AE,CRF07_BC,and CRF08_BC are the three major strains of HIV-infected men≥50 years old newly reported in Guangxi,2020,and the pretreatment drug resistance demonstrates low prevalence.

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

Journal of Gastric Cancer 2023;23(2):340-354
Purpose:
Gastric cancer (GC) is the second most lethal cancer globally and is associated with poor prognosis. Fatty acid-binding proteins (FABPs) can regulate biological properties of carcinoma cells. FABP5 is overexpressed in many types of cancers; however, the role and mechanisms of action of FABP5 in GC remain unclear. In this study, we aimed to evaluate the clinical and biological functions of FABP5 in GC.
Materials and Methods:
We assessed FABP5 expression using immunohistochemical analysis in 79 patients with GC and evaluated its biological functions following in vitro and in vivo ectopic expression. FABP5 targets relevant to GC progression were determined using RNA sequencing (RNA-seq).
Results:
Elevated FABP5 expression was closely associated with poor outcomes, and ectopic expression of FABP5 promoted proliferation, invasion, migration, and carcinogenicity of GC cells, thus suggesting its potential tumor-promoting role in GC. Additionally, RNA-seq analysis indicated that FABP5 activates immune-related pathways, including cytokinecytokine receptor interaction pathways, interleukin-17 signaling, and tumor necrosis factor signaling, suggesting an important rationale for the possible development of therapies that combine FABP5-targeted drugs with immunotherapeutics.
Conclusions
These findings highlight the biological mechanisms and clinical implications of FABP5 in GC and suggest its potential as an adverse prognostic factor and/or therapeutic target.

Objective: To explore the family rehabilitation model for children with scar contracture after hand burns and observe its efficacy. Methods: A retrospective non-randomized controlled study was conducted. From March 2020 to March 2021, 30 children with scar contracture after deep partial-thickness to full-thickness burns of hands, who met the inclusion criteria, were hospitalized in the Burn Center of PLA of the First Affiliated Hospital of Air Force Medical University. According to the rehabilitation model adopted, 18 children (23 affected hands) were included in a group mainly treated by family rehabilitation (hereinafter referred to as family rehabilitation group), and 12 children (15 affected hands) were included in another group mainly treated by hospital rehabilitation (hereinafter referred to as hospital rehabilitation group). In the former group, there were 11 males and 7 females, aged (4.8±2.1) years, who began rehabilitation treatment (3.1±0.8) d after wound healing; in the latter group, there were 7 males and 5 females, aged (4.6±2.1) years, who began rehabilitation treatment (2.8±0.7) d after wound healing. The children in hospital rehabilitation group mainly received active and passive rehabilitation training in the hospital, supplemented by independent rehabilitation training after returning home; after 1-2 weeks of active and passive rehabilitation training in the hospital, the children in family rehabilitation group received active and passive rehabilitation training at home under the guidance of rehabilitation therapists through WeChat platform. Both groups of children were treated for 6 months. During the treatment, they wore pressure gloves and used hand flexion training belts and finger splitting braces. Before treatment and after 6 months of treatment, the modified Vancouver scar scale, the total active movement of the hand method, and Carroll quantitative test of upper extremity function were used to score/rate the scar of the affected hand (with the difference of scar score between before treatment and after treatment being calculated), the joint range of motion (with excellent and good ratio being calculated), and the function of the affected limb, respectively. Data were statistically analyzed with independent sample t test, equivalence test, Fisher's exact probability test, and Mann-Whitney U test. Results: The differences of scar scores of the affected hands of children in family rehabilitation group and hospital rehabilitation group between after 6 months of treatment and those before treatment were 3.0 (2.0, 7.0) and 3.0 (2.0, 8.0) respectively (with 95% confidence interval of 2.37-5.38 and 1.95-5.91). The 95% confidence interval of the difference between the differences of the two groups was -2.43-2.21, which was within the equivalent boundary value of -3-3 (P<0.05). The excellent and good ratios of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group were 3/23 and 2/15 respectively before treatment, and 15/23 and 12/15 respectively after 6 months of treatment. The ratings of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.58 and 2.30, respectively, P<0.05), but the ratings of joint range of motion of the affected hand between the two groups were similar before treatment and after 6 months of treatment (with Z values of 0.39 and 0.55, respectively, P>0.05). The functional ratings of the affected limbs of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.98 and 3.51, respectively, P<0.05), but the functional ratings of the affected limbs between the two groups were similar before treatment and after 6 months of treatment (with Z values of 1.27 and 0.38, respectively, P>0.05). Conclusions: The WeChat platform assisted rehabilitation treatment with mainly family rehabilitation, combined with hand flexion and extension brace can effectively reduce the scarring after children's hand burns, improve the joint range of motion of the affected hands, and promote the recovery of affected limb function. The effect is similar to that of hospital-based rehabilitation providing an optional rehabilitation, treatment method for children who cannot continue to receive treatment in hospital.
