Efficacy and safety of neoadjuvant sintilimab in combination with FLOT chemotherapy in patients with HER2-negative locally advanced gastric or gastroesophageal junction adenocarcinoma: an investigator-initiated, single-arm, open-label, phase II study.

BACKGROUND: The addition of immune checkpoint inhibitors to neoadjuvant chemotherapy in operable advanced gastric or gastroesophageal junction (G/GEJ) cancer aroused wide interest. This study was designed to assess the efficacy and safety of neoadjuvant sintilimab, a programmed cell death protein-1 (PD-1) inhibitor, in combination with fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) chemotherapy for HER2-negative locally advanced G/GEJ cancer. METHODS: Eligible patients with clinical stage cT4 and/or cN+M0 G/GEJ cancer were enroled in this phase II study. Patients received neoadjuvant sintilimab (200 mg every 3 weeks) for three cycles plus FLOT (50 mg/m 2 docetaxel, 80 mg/m 2 oxaliplatin, 200 mg/m 2 calcium levofolinate, 2600 mg/m 2 5-fluorouracil every 2 weeks) for four cycles before surgery, followed by four cycles of adjuvant FLOT with same dosages after resection. The primary endpoint was the pathological complete response (pCR) rate. RESULTS: Thirty-two patients were enroled between August 2019 and September 2021, with a median follow-up of 34.8 (95% CI, 32.8-42.9) months. Thirty-two (100%) patients received neoadjuvant therapy, and 29 underwent surgery with an R0 resection rate of 93.1%. The pCR (TRG0) was achieved in 5 (17.2%; 95% CI, 5.8-35.8%) patients, and the major pathological response was 55.2%. Twenty-three (79.3%) patients had T downstaging, 21 (72.4%) had N downstaging, and 19 (65.5%) had overall TNM downstaging. Six (20.7%) patients experienced recurrence. Patients achieving pCR showed better event-free survival (EFS), disease-free survival (DFS), and overall survival (OS) than non-pCR. The estimated 3-year EFS rate, 3-year DFS rate, and 3-year OS rate were 71.4% (95% CI, 57.2-89.2%), 78.8% (95% CI, 65.1-95.5%), and 70.9% (95% CI, 54.8-91.6%), respectively. The objective response rate and disease control rate were 84.4% (95% CI, 68.3-93.1%) and 96.9% (95% CI, 84.3-99.5%), respectively. Twenty-five (86.2%) received adjuvant therapy. The main grade ≥3 treatment-related adverse events (TRAEs) were lymphopenia (34.4%), neutropenia (28.1%), and leukopenia (15.6%). no patients died from TRAE. The LDH level exhibited a better predictive value to pathological responses than PD-L1 and MSI status. CONCLUSIONS: The study demonstrated an encouraging efficacy and manageable safety profile of neoadjuvant sintilimab plus FLOT in HER2-negative locally advanced G/GEJ cancer, which suggested a potential therapeutic option for this population.

Development of sensory integration therapy in Mainland China: A comprehensive study with bibliometrics and visualization techniques.

Sensory integration therapy (SIT) is an intervention to improve the developmental and learning problems in children. It was introduced in China from late 1980 s to early 1990 s and has received considerable attention from scholars. However, due to its late development in China and its specialised nature, it is worth exploring in depth whether it is recognized by the general public and how it is researched by academics. Therefore, we used Internet survey approach to explore the actual feedback of users towards SIT through the Internet. At the same time, bibliometric method and visualization techniques were used to study 892 journal articles on SIT in CNKI, Wanfang Database and VIP Database to analyze the spatial and temporal distribution, subject distribution, keyword co-occurrence, and keyword clustering of SIT research in mainland China since it came to China mainland. We found that the research on SIT in mainland China has been fruitful. However, the public is less aware of its basic function, therapeutic effects, and necessity. Our findings point to the need to raise awareness of sensory integration disorder and sensory integration therapy among the general public, and to strengthen academic research on sensory integration therapy.

[Effect of transcutaneous auricular vagus nerve stimulation on nocturnal autonomic nervous function in primary insomnia patients].

OBJECTIVE: To observe the effect of transcutaneous auricular vagus nerve stimulation (taVNS) on the sleep quality and nocturnal heart rate variability (HRV) in patients with primary insomnia. METHODS: Twenty-one patients with primary insomnia were included. Using SDZ-ⅡB electric acupuncture apparatus, Xin (CO15) and Shen (CO10) were stimulated with disperse-dense wave, 4 Hz/ 20 Hz in frequency, (0.2±30%) ms of pulse width and tolerable intensity. Electric stimulation was given once every morning and evening of a day, 30 min each time, for 4 weeks totally. Before and after treatment, the score of Pittsburgh sleep quality index (PSQI), objective sleep structure (total sleep time [TST], sleep latency [SL], wake after sleep onset [WASO], sleep efficiency [SE], the percentages of non-rapid eye movement period 1, 2, 3, and the percentage of rapid eye movement period to TST [N1%, N2%, N3%, REM%] ) and nocturnal HRV (high frequency [HF], low frequency [LF], the ratio of LF to HF [LF/HF], standard deviation for the normal RR intervals [SDNN], squared root of the mean sum of squares of differences between adjacent intervals RR [RMSSD], the percentage of adjacent RR intervals with differences larger than 50 ms in the entire recording [PNN50%], the mean of sinus RR intervals [NNMean] ) were compared in the patients separately. RESULTS: After treatment, the score of each item and the total score of PSQI and SL were all reduced as compared with those before treatment (P<0.01, P<0.001); SE, N3%, LF, HF, LF/HF, SDNN, NNMean and RMSSD were all increased compared with those before treatment (P<0.001, P<0.01). CONCLUSION: The taVNS improves the sleep quality and objective sleep structure in patients with primary insomnia, which is probably related to the regulation of autonomic nervous functions.

Design, synthesis, biological evaluation and molecular dynamics simulation studies of imidazolidine-2,4-dione derivatives as novel PTP1B inhibitors.

Protein tyrosine phosphatase 1B (PTP1B) is a member of the phosphotyrosine phosphatase family and plays an important role in the signal transduction of diabetes. Inhibition of PTP1B activity can increase insulin sensitivity and reduce blood sugar levels. Therefore, it is urgent to find compounds with novel structures that can inhibit PTP1B. This study designed imidazolidine-2,4-dione derivatives through the computer-aided drug design (CADD) strategy, and the Comp#10 showed outstanding inhibitory ability. (IC50 = 2.07 µM) and selectivity. The inhibitory mechanism at molecular level of Comp#10 on PTP1B was studied by molecular dynamics simulation. The results show that the catalytic region of PTP1B protein is more stable, which makes the catalytic sites unsuitable for exposure. Interestingly, the most obvious changes in the interaction between residues in the P-loop region (such as: His214, Cys215, and Ser216). In short, this study reported for the first time that imidazolidine-2,4-dione derivatives as novel PTP1B inhibitors had good inhibitory activity and selectivity, providing new ideas for the development of small molecule PTP1B inhibitors.

The results showed that:(1)from the perspective of yield and economic benefits, M75 was the best and M100 second;(2)for effective components, the combined application of organic and chemical fertilizers increased the content of main water-soluble components and the total content of effective components, among which M25 and M50 were better.

The Application of Hypnosis in Sports.

As an ancient science, hypnosis has been used by humans since the primitive societies during theocratic times. By the 20th century, scientists and psychologists had re-recognized and studied hypnosis and explored its applications in fields such as medicine, education, and military uses. A local form of traditional Chinese "hypnosis" appeared in Huangdi Neijing, but it has not received enough attention from Chinese people; China's modern hypnosis development is later than that of American and European countries. Therefore, people's understanding and applications of hypnosis remain inadequate. With the development of China's economy and state power in the last decades, Chinese people were beginning to attach importance to the investment and development of the sports industry and realized that the psychological quality of the athletes is often a decisive factor in the success or failure of the competition. Meanwhile, hypnosis is an effective psychological training method to be used in daily training and competitions. In light of this, this essay firstly reviews the history of hypnosis before carrying out the methods of a literature review and a logical analysis to explore the applications of hypnosis in sports. Thus, evidence is provided in favor of the use of hypnosis in the sports industry.

The efficacy and safety of omega-3 fatty acids on depressive symptoms in perinatal women: a meta-analysis of randomized placebo-controlled trials.

Omega-3 fatty acids (FA), as a nutrient, has been proven effective in major depressive disorder (MDD), however, the results of monotherapy in perinatal depression (PND) remain unclear. To examine the efficacy and safety of omega-3 fatty acids (FA) monotherapy for perinatal depression (PND) compared with placebo. PubMed, Embase, PsycINFO, MEDLINE, Cochrane Library, and CINAHL were searched from inception up to November 2019. The reference lists of relevant review articles and included studies were also reviewed. Randomized placebo-controlled trials examining the efficacy and safety of omega-3 FA monotherapy in perinatal women with depressive symptoms were included. Pooled standard mean differences (SMD) were calculated and random-effects models were adopted for all analyses. Subgroups analyses and meta-regression were performed to quantify characteristics of the subjects and trials influencing the omega-3 response. In addition, meta-regression was conducted to identify the source of heterogeneity. The study protocol was registered at PROSPERO, CRD42020159542. Eight eligible randomized placebo-controlled trials were included involving 638 participants. There was a significant effect of omega-3 FA on perinatal depression. Omega-3 with higher ratio of EPA/DHA (≥1.5) had significant efficacy both in mild-to-moderate pregnant and postpartum depression with low incidence of side effects. Among the included trials reporting adverse effects, there was no significant difference in incidence of gastrointestinal and neurologic events between the omega-3 and placebo groups. There was no evidence of publication bias. Our findings suggested that omega-3 FA significantly improved depressive symptoms in perinatal women regardless of pregnant or postpartum and well-tolerated. Furthermore, the omega-3 response was linked to higher EPA proportion in omega-3 formula and mild- to-moderate depression.

Inhibitory Effects of Antiviral Drug Candidates on Canine Parvovirus in F81 cells.

Canine parvovirus (CPV) is a common etiological agent of acute enteritis, which occurs globally in domestic and wild carnivores. Despite the widespread use of inactivated or live attenuated vaccines, the emergence of antigenic variants and the influence of maternal antibodies have raised some concerns regarding the efficacy of commercial vaccines. While no specific antiviral therapy for CPV infection exists, the only treatment option for the infection is supportive therapy based on symptoms. Thus, there is an urgent medical need to develop antiviral therapeutic options to reduce the burden of CPV-related disease. In this study, a cytopathic effect (CPE)-based high-throughput screening assay was used to screen CPV inhibitors from a Food and Drug Administration (FDA)-approved drug library. After two rounds of screening, seven out of 1430 screened drugs were found to have >50% CPE inhibition. Three drugs-Nitazoxanide, Closantel Sodium, and Closantel-with higher anti-CPV effects were further evaluated in F81 cells by absolute PCR quantification and indirect immunofluorescence assay (IFA). The inhibitory effects of all three drugs were dose-dependent. Time of addition assay indicated that the drugs inhibited the early processes of the CPV replication cycle, and the inhibition effects were relatively high within 2 h postinfection. Western blot assay also showed that the three drugs had broad-spectrum antiviral activity against different subspecies of three CPV variants. In addition, antiapoptotic effects were observed within 12 h in Nitazoxanide-treated F81 cells regardless of CPV infection, while Closantel Sodium- or Closantel-treated cells had no pro- or antiapoptotic effects. In conclusion, Nitazoxanide, Closantel Sodium, and Closantel can effectively inhibit different subspecies of CPV. Since the safety profiles of FDA-approved drugs have already been extensively studied, these three drugs can potentially become specific and effective anti-CPV drugs.

The characteristics and clinical outcome of drug-induced liver injury in a Chinese hospital: A retrospective cohort study.

The aim of this cohort study was to determine the characteristics and clinical outcome of 287 patients with drug-induced liver injury (DILI) in a Chinese hospital.Between January 2008 and January 2013, individuals who were diagnosed with DILI were selected. The complete medical records of each case were reviewed, and factors for the outcome of patients with DILI were extracted and analyzed using univariate and multivariate analysis.Two hundred eighty-seven cases identified as DILI were included in the study. A total of 105 different drugs were considered to be related to the hepatotoxicity. The main causative group of drugs was Chinese herb (n = 111). Liver failure developed in 9 (3.1%) patients, and 2 died (0.7%). Overall, complete recovery occurred in 92 (32.1%) patients. Univariate analysis and binary logistic regression analysis identified the digestive symptoms, jaundice, total bilirubin (TBIL), and direct bilirubin (DBIL) as independent factors for the non-recovery of DILI. Then the prediction model, including digestive symptoms, jaundice, TBIL, and DBIL, was built by using binary logistic regression analysis again. Receiver operating characteristic curve validated the strong power (area under the curve (AUC) = 0.907) of prediction model for predicting the DILI non-recovery.DILI is an important cause of liver test abnormalities, and Chinese herb represented the most common drug group. The factors such as digestive symptoms, jaundice, TBIL, and DBIL have effect on DILI outcomes. The prediction model, including digestive symptoms, jaundice, TBIL, and DBIL, established in this study is really an excellent predictive tool for non-recovery of DILI patients.

Effect of conditioned stimulus exposure during slow wave sleep on fear memory extinction in humans.

STUDY OBJECTIVES: Repeated exposure to a neutral conditioned stimulus (CS) in the absence of a noxious unconditioned stimulus (US) elicits fear memory extinction. The aim of the current study was to investigate the effects of mild tone exposure (CS) during slow wave sleep (SWS) on fear memory extinction in humans. DESIGN: The healthy volunteers underwent an auditory fear conditioning paradigm on the experimental night, during which tones served as the CS, and a mild shock served as the US. They were then randomly assigned to four groups. Three groups were exposed to the CS for 3 or 10 min or an irrelevant tone (control stimulus, CtrS) for 10 min during SWS. The fourth group served as controls and was not subjected to any interventions. All of the subjects completed a memory test 4 h after SWS-rich stage to evaluate the effect on fear extinction. Moreover, we conducted similar experiments using an independent group of subjects during the daytime to test whether the memory extinction effect was specific to the sleep condition. PARTICIPANTS: Ninety-six healthy volunteers (44 males) aged 18-28 y. MEASUREMENTS AND RESULTS: Participants exhibited undisturbed sleep during 2 consecutive nights, as assessed by sleep variables (all P > 0.05) from polysomnographic recordings and power spectral analysis. Participants who were re-exposed to the 10 min CS either during SWS and wakefulness exhibited attenuated fear responses (wake-10 min CS, P < 0.05; SWS-10 min CS, P < 0.01). CONCLUSIONS: Conditioned stimulus re-exposure during SWS promoted fear memory extinction without altering sleep profiles.

[Discussion on professor SHAO Jing-Ming's academic opinion of focusing spirit].

During professor SHAO Jing-ming's academic research and medical practice, his academic opinion of focusing spirit is gradually developed. In terms of nurturing the spirit, attention should be paid on persistence as well as everyday health maintenance and exercise to nurture the spirit of physician. In terms of clinical diagnosis and treatment, patients' psychology, employment and life status should be observed and experienced, which could bring more methods to take essential care of patients' spirit. The treatment should work with psychological counseling, advocating that based on patients' qi and spirit, various forms of treatment methods should be properly used, such as acupuncture or moxibustion or combination of acupuncture and medicine, along with simple acupoint selection and harmony medication. Before clinical treatment of acupuncture, calming the mind is critically emphasized to make a clear diagnosis. During the acupuncture, calming and focusing the mind is necessary as well as emphasizing the details, so acupuncture could be integrated with Chi Gong to create a new warming-sensation technique. In a word, the academic opinion of focusing spirit is shedding an inspiring light upon further study.

[Asthma at acute attack stage treated with "Shao's five needling therapy": a multi-central randomized controlled study].

OBJECTIVE: To evaluate the clinical efficacy of asthma at acute attack stage treated with "Shao's five needling therapy". METHODS: The randomized controlled method was applied to divide 210 cases into an observation group and a control group, 105 cases in each one. In the observation group, "Shao's five needling therapy" [Feishu (BL 13), Dazhui (GV 14), Fengmen (BL 12)] and the combined therapy were adopted, including oxygen uptake, aerosol inhalation and oral administration of prednisone. In the control group, the oral administration of theophylline sustained release tablet and the combined therapy were applied. The treatment was continued for 7 days. The clinical symptoms and physical signs such as wheezing, cough, expectoration, chest stuffiness, wheezing rale and shortness of breath, as well as lung function indices such as forced expiratory volume one second (FEV1) and peak expiratory flow (PEF) were observed before and after treatment in the two groups. METHODS: In the observation group, 69 cases were cured clinically, 20 cases effective remarkably, 7 cases effective and 0 case failed. In the control group, 49 cases were cured clinically, 31 cases effective remarkably, 15 cases effective and 0 case failed. The difference in the efficacy was significant in comparison of the two groups (P < 0.05). The therapeutic effect in the observation group was better than that in the control group. The total score of the symptoms and physical signs, FEV1 and PEF after treatment were all improved significantly in the two groups (all P < 0.01). And the results in the observation group were better than those in the control group (all P < 0.01). CONCLUSION: "Shao's five needling therapy" achieves the significant efficacy on asthma at acute attack stage. It significantly relieves the symptoms and physical signs of the patients and improves lung functions. The effect is better than that of theophylline sustained release tablet.

Design, synthesis, biological activity and molecular dynamics studies of specific protein tyrosine phosphatase 1B inhibitors over SHP-2.

Over expressing in PTPN1 (encoding Protein tyrosine phosphatase 1B, PTP1B), a protein tyrosine phosphatase (PTP) that plays an overall positive role in insulin signaling, is linked to the pathogenesis of diabetes and obesity. The relationship between PTP1B and human diseases exhibits PTP1B as the target to treat these diseases. In this article, small weight molecules of the imidazolidine series were screened from databases and optimized on silicon as the inhibitors of PTP1B based on the steric conformation and electronic configuration of thiazolidinedione (TZD) compounds. The top three candidates were tested using an in vitro biological assay after synthesis. Finally, we report a novel inhibitor, Compound 13, that specifically inhibits PTP1B over the closely related phosphatase Src homology 2 (SH2) domain-containing phosphatase 2 (SHP-2) at 80 µΜ. Its IC50 values are reported in this paper as well. This compound was further verified by computer analysis for its ability to combine the catalytic domains of PTP1B and SHP-2 by molecular dynamics (MD) simulations.

[Inhibitory effect of Tanreqing injection on proliferation of T lymphoblastic leukemia cell line Molt4 in vitro and its mechanism].

This study was purposed to explore the effects of Tanreqing injection on the biologic activities of human acute T lymphoblastic leukemia cell line Molt4 in vitro and its mechanism. Tanreqing injection was proportionally diluted and divided into 9 groups of different concentrations, including 1:2, 1:4, 1:8, 1:16, 1:32, 1:64, 1:128, 1:256 and 1:512. Molt4 cells were treated with those different concentrations of Tanreqing injection, and the cell growth status at various time points of different concentrations was observed under microscope. CCK-8 assay was employed to detect ability of cell proliferation, growth curve was drawn, the inhibition ratio and 50% inhibiting concentration (IC(50)) were calculated. Flow cytometry with PI and PI/Annexin V double stainings were used to detect the cell cycle and apoptosis of Molt4 cells after the treatment of Tanreqing injection respectively. Caspase-3 and Bcl-2 mRNA expression of Molt4 cells were determined by real-time quantitative PCR. The results showed that Tanreqing injection displayed an inhibitory effect on the proliferation of Molt4 cell line. In 1:2, 1:4, 1:8 and 1:16 concentration groups, great cytotoxicity was observed and numerous cells were dead. The inhibitory effect of Tanreqing injection was dose-dependent. IC(50) was 1:142 dilution concentration. In the 1:32 concentration group, S phase cell quantity remarkably decreased (p < 0.05) and apoptosis rate significantly increased (p < 0.05) at 72 hours after Tanreqing injection treatment. Simultaneously, caspase-3 mRNA expression increased and Bcl-2 mRNA expressions was downregulated (p < 0.05). It is concluded that the Tanreqing injection has an inhibitory effect on Molt4 cell proliferation and promotes its apoptosis. These biological effects of Tanreqing injection are partly related to cell reduction in S phase, downregulation of bcl-2 gene and upregulation of caspase 3.

[Application of Markov model in post-marketing pharmacoeconomic evaluation of traditional Chinese medicine].

In post-marketing study of traditional Chinese medicine (TCM), pharmacoeconomic evaluation has an important applied significance. However, the economic literatures of TCM have been unable to fully and accurately reflect the unique overall outcomes of treatment with TCM. For the special nature of TCM itself, we recommend that Markov model could be introduced into post-marketing pharmacoeconomic evaluation of TCM, and also explore the feasibility of model application. Markov model can extrapolate the study time horizon, suit with effectiveness indicators of TCM, and provide measurable comprehensive outcome. In addition, Markov model can promote the development of TCM quality of life scale and the methodology of post-marketing pharmacoeconomic evaluation.

[Clinical orientation and thought on several problems in post-marketed reassessment of traditional Chinese medicine].

The post-marketed reassessment is an important link to ensure the safety and effectiveness of traditional chinese medicine. It is also the expansion and stretch of new drug evaluation. Through the systematic, standard, rigorous post-marketed reassessment, the enterprise can full access to drugs after listing the efficacy and safety information, evaluate the interests and risk of the drug and provide the scientific basis for the drug use. It can also provide timely, scientific technology basis for government health decisions, the enterprise marketing decision and public health security. This paper mainly discussed the thought on clinical orientation of traditional chinese medicine in the post-marketed reassessment and how to reach the goal through systematic consideration and overall plan.
