OBJECTIVE To comparatively analyze tumor staging versus clinical staging in reimbursement scope restrictions under medical insurance for antineoplastic agents in order to better implement the medicare drug payment policy. METHODS Antineoplastic agents included in the National Basic Medical Insurance， Workers’ Compensation Insurance and Maternity Insurance Drug Catalogue （2024） （hereinafter referred to as the “Medical Insurance Catalog”） were used as research subject to compile and analyze reimbursement scope restrictions regarding tumor staging. By consulting clinical diagnosis and treatment guidelines and relevant literature， the tumor staging in reimbursement scope restrictions of the Medical Insurance Catalog was mapped and compared with clinical staging. RESULTS & CONCLUSIONS A total of 89 antineoplastic agents’ medical insurance payments had tumor staging. Among these， there were 86 western drugs （including 17 ordinary western drugs， 68 negotiated drugs， and 1 competitive drug） and 3 Chinese patent medicines （including 1 ordinary Chinese patent medicine and 2 negotiated drugs）. Non-small cell lung cancer involved the most restricted payment drugs， with 36 drugs. The tumor staging in reimbursement scope restrictions was mostly “metastatic” and “locally advanced”， involving 67 and 48 drugs respectively. Tumor staging in most reimbursement scope restrictions could correspond to the clinical staging of the tumor. However， mid-advanced esophageal cancer， unresectable gastrointestinal stromal tumors， unresectable locally advanced neuroendocrine tumors， locally advanced basal cell carcinoma， and unresectable neurofibromatosis type Ⅰ did not have a corresponding clinical staging mentioned in authoritative guidelines or high-quality clinical studies and need to be determined by the clinic according to the actual situation of the patient. Therefore， it is recommended that the interpretation of tumor staging in reimbursement scope restrictions should be accurately defined and standardized， so as to improve the accuracy of the drug payment policy in the actual implementation process.

OBJECTIVE To investigate ameliorative effects and mechanisms of two probiotics （Bacillus subtilis， Lactobacillus acidophilus） combined with Aurantii Fructus Immaturus （AFI） on functional dyspepsia （FD） in rats. METHODS Rats were randomly divided into blank group， model group， positive control group （domperidone group， 2.7 mg/kg）， AFI group （9 g/kg）， L. acidophilus group （5×107 cfu/kg）， B. subtilis group （5×107 cfu/kg）， L. acidophilus+ AFI group （L. acidophilus 5×107 cfu/kg+ AFI 9 g/kg）， and B. subtilis+AFI group （B. subtilis 5×107 cfu/kg+AFI 9 g/kg）， with 8 rats in each group. Except for the blank group， FD model was established by tail-clamping stimulation+hunger and satiety disorder+swimming exhaustion in other groups. After modeling， each group was given the corresponding drug/probiotic suspensions/physiological saline intragastrically， once a day， for 14 consecutive days. After the last medication， gastric emptying rate and the rate of propulsion of the small intestine in rats were measured； the levels of brain-gut peptide-related indicators [gastrin （GAS）， substance P （SP）， vasoactive intestinal peptide （VIP）， somatostatin （SS） and cholecystokinin （CCK）] in the serum of rats were measured. The pathological morphology of the gastric antrum tissue and duodenal tissue was observed. Cecal contents from the rats were collected for gut microbiota sequencing analysis. The protein expression levels of tyrosine kinase receptor c-Kit and stem cell factor （SCF） in the gastric antrum tissue， as well as Toll-like receptor 4 （TLR4）， myeloid differentiation factor 88 （MyD88）， and nuclear factor κB （NF-κB） in the duodenal tissue of the rats were detected. RESULTS Compared with the blank group， model group showed significantly lower gastric emptying rate， small intestinal propulsion rate， serum levels of GAS and SP， relative abundance of Firmicutes， Ace， Chao and Sobs indexes of the gut microbiota， and protein levels of SCF and c-Kit in gastric antrum （P＜0.05）， while serum levels of VIP， SS and CCK， relative abundance of Bacteroidetes， as well as protein expressions of TLR4， MyD88， and NF-κB， were significantly higher （P＜0.05）. The histological structure JZYC23S53） of the gastric antrum tissue appeared basically normal； however， abnormalities were observed in the duodenal structure， with a significant infiltration of inflammatory cells visible. Compared with the model group， all treatment groups significantly modulated most of the above indexes （P＜0.05）. The histological structure of the gastric antrum tissue was normal. Except for the B. subtilis group and the B. subtilis+AFI group， the pathological states of the duodenum in the remaining rats gradually recovered. Compared with each single drug group， most of above indexes in rats from each combination group showed further improvement （P＜0.05）. CONCLUSIONS The combination of AFI with two probiotics can improve gastrointestinal motility in FD rats， and the effect is superior to that of using the drugs alone. The specific underlying mechanisms may be related to the activation of the SCF/c-Kit signaling pathway and the inhibition of the TLR4/MyD88/NF-κB signaling pathway.

ObjectiveTo investigate the relationship between the non-fasting triglyceride and glucose （TyG） index and hyperglycemia in pregnancy during the third trimester in high altitudes. MethodsThis study selected clinical and laboratory data of 774 Tibetan singleton pregnant women who delivered at Chaya People's Hospital of Qamdo city in Xizang autonomous region， from January 2023 to April 2025. The non-fasting TyG index was calculated from non-fasting triglyceride （TG） and random plasma glucose （PG）. Based on the tertiles of the non-fasting TyG index values， the individuals were split into three groups （corresponding to non-fasting TyG index of 8.89 and 9.21， respectively）. The baseline clinical characteristics， lipid levels and the occurrence of developing hyperglycemia in pregnancy were compared among the three groups. Statistical analyses were performed using ANOVA， Kruskal-Wallis H test， Chi-square test， or Fisher exact test and the relationship between the non-fasting TyG index and hyperglycemia in pregnancy were examined using multivariate logistic regression models and curve fitting. ResultsA total of 774 Tibetan singleton pregnant women were included， with a average age of 27.3 ± 6.1 years， a pre-delivery body mass index （Pre-BMI） of （25.2±2.3）kg/m² ， a proportion of 26.7% （207/774） primigravid women， the mean non-fasting TyG index was 9.1 ± 0.4。Thirty pregnant women were diagnosed with hyperglycemia in pregnancy， with a detection rate of 3.9% （30/774）. Statistically significant differences in serum total cholesterol （TC）， TG， low-density lipoprotein cholesterol （LDL-C） and high-density lipoprotein cholesterol （HDL-C） levels were identified when comparing different non-fasting TyG groups （all P values <0.05）. Subsequent trend test analysis indicated that the levels of TC， TG， LDL-C， and PG gradually increased with elevated the non-fasting TyG index （ F_{trend TC}=95.61， P<0.001； F_{trend TG}=1 051.91， P<0.001； F_{trend LDL-C} = 97.20， P < 0.001； F_{trend TG}=195.20； P<0.001）. After adjustment for maternal age， pre-delivery BMI， altitude， TC， LDL-C， and HDL-C， multivariate Logistic regression models revealed independent positive associations between non-fasting TyG index and hyperglycemia in pregnancy （Model 1： OR=2.72， 95% CI： 1.13-6.53， P=0.026； Model 2： OR=2.56， 95% CI： 1.01-6.50， P=0.048； Model 3： OR=2.72， 95% CI： 1.06-6.97， P=0.037； Model 4： OR=4.02， 95% CI： 1.42-11.40， P=0.009） and the incident of hyperglycemia in pregnancy showed an increasing tendency as increasing with the non-fasting TyG index， however， this association did not statistical significance （P _trend >0.05）. Curve fitting by restricted cubic splines （RCS） were used to assess linearity between non-fasting TyG and hyperglycemia in pregnancy， and there was a linear dose-response relationship between non-fasting TyG and hyperglycemia in pregnancy （P _{for non-linear} = 0.515）. ConclusionNon-fasting TyG index in the third trimester is a risk factor for hyperglycemia in pregnancy among the Tibetan singleton pregnant women at high altitudes and there was a possible linear dose-response relationship between the non-fasting TyG index and hyperglycemia in pregnancy.

Dysfunction of anti-tumor immune responses is crucial for cancer progression. Immune checkpoint blockade (ICB), which can potentiate T cell responses, is an effective strategy for the normalization of host anti-tumor immunity. In recent years, immune checkpoints, expressed on both tumor cells and immune cells, have been identified; some of them have exhibited potential druggability and have been approved by the US Food and Drug Administration (FDA) for clinical treatment. However, limited responses and immune-related adverse events (irAEs) cannot be ignored. This review outlines the development and applications of ICBs, potential strategies for overcoming resistance, and future directions for ICB-based cancer immunotherapy.

piRNA is a class of small non-coding RNA which specifically binds with PIWI protein. It is mainly expressed in germ cells and involved in the regulation of spermatogenesis. The role of piRNA pathway in the regulation of spermatogenesis mainly includes inhibition of transposons, induction of mRNA translation or degradation, and mediation of degradation of Miwi ubiquitination in late-stage sperm cells. With the detection of piRNA in seminal plasma, more attention has been attracted to whether piRNA can be used as a non-invasive molecular biomarker for the evaluation of spermatogenesis. This paper has reviewed recent studies on the mechanism of piRNA pathways mediating spermatogenesis and potential roles of piRNA disorders in the diagnosis and treatment of male infertility.

Bariatric surgery may cause intestinal microecological environment imbalance due to changes in gastrointestinal anatomy.Some patients may have compli-cations,even regain weight.Probiotics can act on intestinal mucosa,epithelium and gut-associated lymphoid tissue to improve the intestinal microecological environment of obese patients after bariatric surgery.Probiotics can promote the production of short-chain fatty acids,stimulate intestinal cells to release glucagon-like peptide-1,peptide tyrosine-tyrosine,insulin and other endocrine hormones,affect the function of the central nervous system through the gut-brain axis,make patients after bariatric surgery feel full,and reduce blood sugar at the same time.Probiotics can produce lactic acid,acetic acid and lactase,to inhibit the growth of harmful bacteria and to improve gastrointestinal symptoms of patients after bariatric surgery.Probiotics can activate the AMP-activated protein kinase signaling pathway,improve lipid metabolism,and promote the recovery of symptom indicators of nonalcoholic fatty liver disease after bariatric surgery.Probiotics can regulate the release of neurotransmitters or metabolites by the microbiota through the gut-brain axis to affect brain activity and behavior,thus helping patients improve negative emotions after bariatric surgery.This article describes the intestinal microecological environment of obese patients and mechanism of the change after bariatric surgery and summarizes the effects and possible mechanisms of probiotics in improving the intestinal microecological environment of obese patients after bariatric surgery,to provide references for promoting the clinical application of probiotics.

Objective To investigate the effects of remazolam on melatonin secretion,sleep rhythm and postoperative delirium(POD)in elderly patients undergoing spinal surgery.Methods A total of 160 elderly patients,76 males and 84 females,aged 65-80 years,BMI 18.5-24.0 kg/m2,ASA physical status Ⅱ or Ⅲ,from November 2023 to January 2024 undergoing spinal surgery(lumbar interbody fusion,posterior approach)under general anesthesia were selected.The patients were divided into two groups by random number table method:the remazolam group(group R)and the propofol group(group P),80 pa-tients in each group.Group R was given remazolam 0.3 mg/kg for anesthesia induction,and then continued to pump remazolam 0.3-0.8 mg·kg-1·h-1 for anesthesia maintenance.Group P was given propofol 2.0 mg/kg for anesthesia induction,and then continued to pump propofol 4-6 mg·kg-1·h-1 for anesthesia maintenance.The levels of melatonin and cortisol were recorded at 04:00 a.m.on the day of surgery,1 day,2 and 3 days after surgery.Pittsburgh sleep quality index(PSQI)and VAS pain scores at rest were recorded 1 day before surgery,1 day and 2 days after surgery and before discharge.The occurrence of POD and post-operative sleep disorder(POSD)were recorded.The duration of extubation,PACU stay time,total analgesia pump compressions,effective analgesia pump compressions,number of remedial analgesia cases,intraoperative hypotension,postoperative nausea and vomiting,dizziness,respiratory depression and other adverse events were recorded.Results Compared with group P,the extubation time and PACU residence time in group R were significantly shortened(P＜0.05),the level of melatonin was significantly increased while the level of cortisol was significantly decreased at 4:00 a.m.,and the PSQI was significantly decreased 1 day after surgery(P＜0.05),the incidence of POD,POSD,and intraoperative hypotension were signifi-cantly decreased(P＜0.05).There were no significant differences in extubation time,total and effective times of analgesic pump,rate of remedial analgesia,intraoperative hypotension,postoperative nausea,vom-iting,dizziness and respiratory depression between the two groups.Conclusion Remazolam has little effect on the secretion rhythm of melatonin and cortisol and the sleep rhythm after spinal surgery in elderly pa-tients,and the recovery is faster,which can reduce the incidence of POD and alleviate the sleep disorder af-ter spinal surgery.

The STAR tool was used to evaluate and analyze the science, transparency, and applicability of Chinese pathology guidelines and consensus published in medical journals in 2022. There were a total of 18 pathology guidelines and consensuses published in 2022, including 1 guideline and 17 consensuses. The results showed that the guideline score was 21.83 points, lower than the overall guideline average (43.4 points). Consensus ratings scored an average of 27.87 points, on par with the overall consensus level (28.3 points). Areas that scored above the overall level were "conflict of interest" and "working groups", while areas that scored below the overall level were "proposals", "funding", "evidence", "consensus approaches" and "accessibility". To sum up, the formulation of pathology guidelines and consensuses in 2022 is not standardized, and the evidence retrieval process, evidence evaluation methods and grading criteria for recommendations on clinical issues are not provided in the formulation process; the process and method for reaching consensus are not provided, the plan is lacking, and registration is not carried out. It is therefore suggested that guidelines/consensus makers in the field of pathology should attach importance to evidence-based medical evidence, strictly follow guideline formulation methods and processes, further improve the scientific, applicable and transparent guidelines/consensuses in the field, and better provide support for clinicians and patients.

Objective:To analyze the monitoring results of iodine deficiency disorders (IDD) in Hainan Province from 2011 to 2023, key prevention and control measures taken during this period, and the impact of related events on the monitoring results.Methods:From 2011 to 2023, a systematic sampling method was used to divide 21 cities (districts, counties) in Hainan Province into 5 districts based on east, west, south, north, and center each year. One township (street) was selected from each district, and 40 children aged 8 - 10 (non boarding students) and 20 pregnant women were selected from each township (street) for determination of iodine level of their household salt and urine samples. Based on the monitoring results, the impact of key events such as the pre reduction (2011), post reduction (implementation of new iodized salt standard, 2012 - 2023), salt industry system reform (2017), and the two-year campaign for endemic disease prevention and control (2019, 2000), on the salt iodine coverage rate and qualified iodized salt consumption rate, the urinary iodine level and its distribution in children and pregnant women were analyzed in Hainan Province. B-ultrasound was used to detect the situation of thyroid enlargement was analyzed.Results:(1) In 2011, the median iodine level in edible salt of residents in Hainan Province was 32.1 mg/kg. It was 30.8 mg/kg after the implementation of the new standard in 2012. In 2013, the salt iodine level of residents had significantly decreased to 25.9 mg/kg, with 24.5, 24.2, and 23.8 mg/kg in 2017, 2019, and 2020, respectively. The differences of median salt iodine levels between different years were statistically significant ( H = 29.01, P < 0.001). The coverage rate of iodized salt among residents in Hainan Province from 2011 to 2023 was 98.08% (80 727/82 308), and the difference between different years was statistically significant (χ 2 = 9.51, P = 0.023). The consumption rate of qualified iodized salt was 95.65% (78 738/82 308), and the difference between different years was statistically significant (χ 2 = 21.80, P < 0.001). (2) The median urinary iodine level of children from 2011 to 2023 was 177.5 μg/L, with a median of 204.2 μg/L in 2011. After the implementation of the new standard, the median urinary iodine level of children was 194.9 μg/L in 2012. In 2013, the median urinary iodine level in children decreased to 167.8 μg/L, and had remained within the range of 100 - < 200 μg/L thereafter. In 2017, 2019, and 2020, the median urinary iodine levels were 170.4, 172.8, and 186.3 μg/L, respectively. There was no statistically significant difference in different years ( H = 1.67, P = 0.061). The proportion of children with urinary iodine < 100 μg/L from 2011 to 2023 was 16.29% (8 740/53 634), and the proportion of children with urinary iodine between 100 and < 200 μg/L was 43.96% (23 575/53 634). The differences between different years were statistically significant (χ 2 = 21.50, 23.40, P < 0.001). The childhood goiter rate from 2011 to 2023 was 0.19% (101/53 634). (3) The median urinary iodine level of pregnant women was 153 μg/L in 2011, it was 154.7 μg/L in 2012 after the implementation of the new standard, and it had remained within the range of 100 - < 150 μg/L since then. The median urinary iodine level of pregnant women was 126.2 μg/L in 2013. The median urinary iodine level in 2017, 2019 and 2020 were 123.5, 133.8, and 135.4 μg/L, respectively. There was a statistically significant difference in the median urinary iodine levels of pregnant women between different years ( H = 92.10, P < 0.001). From 2011 to 2023, the proportion of pregnant women with a median urinary iodine level < 150 μg/L was the highest (55.75%, 14 761/26 477). Conclusion:From 2011 to 2023, although the monitoring results of iodine deficiency disorders in children and pregnant women in Hainan Province have fluctuated, they are still in a state of continuous elimination of IDD.
