ObjectiveTo understand the development stages and use of policy tools of general practitioner policies in China since it was first proposed, to summarize the experience and explore the shortcomings, so as to provide references for the adjustment and optimization of China’s general practitioner policies. MethodsContent analysis and mathematical statistics analysis were used to conduct a quantitative research on 111 policy documents with 422 policy items involving general practitioners at the national level from 1997 to 2023, through a three-dimensional analysis framework integrating policy tools, human capital process and policy development stages. ResultsCapacity‑building policy tools were most frequently used in general practitioner policies, and the policy tools gradually shifted from mandate to inducement. The general practitioner policies paid less attention to the career selection link, but paid full attention to every segment of human capital links, with a comprehensive application of policy tools observed in the integrated development stage, despite the existence of unbalanced internal distribution. ConclusionIt is suggested to promote the use of incentive policy tools and to explore multiple approaches based on incentive theory; pay attention to the career selection link for guiding the employment of general practitioners; take the appropriateness between the policy tools and human capital process into comprehensive consideration, striking a dynamic balance of the internal structure of general practitioner policies.

Depression is a widespread psychiatric disorder with complex pathogenesis and unsatisfactory therapeutic effects. As a native flavonoid, Isorhamnetin (ISO) has been deemed to exert neuroprotective effects by antioxidation and regulation of immunity. However, no reports of anti-depressed effect of ISO have yet been found. The present study was conducted to clarify the mechanism basis of anti-depressed effect of ISO utilizing behavioral, biochemical, molecular approaches in vitro and in vivo and bio-informatics analysis. The effects of ISO on depressed mice was investigated through the SPT and FST, and the lesions were examined by H&E staining. Besides, the inflammatory factor and indicator in kynurenine pathway were assessed through detection kits, and the microbiota were checked by 16sRNA. Molecular docking study was performed to investigate the target of ISO. Additionally, Western blot was used to test the activation of PI3K/AKT signaling pathway. The results indicated that ISO could enhance the sugar water preference of mice in SPT and reduce immobility time in FST. Further more, ISO suppressed peripheral and central inflammation, regulated the changes in kynurenine pathway and gut microbiota, inhibited activation of PI3K/AKT pathway, and presented good binding patterns with target proteins on PI3K/AKT signaling pathway. Collectively, these findings demonstrate that ISO alleviated depression-like behaviour by normalizing inflammation-induced dysregulation of the crosstalk between KP and gut microbiota disorder through regulated PI3K/AKT/NF-κB pathway.

ObjectiveTo construct a group-based trajectory model (GBTM) for early medication adherence check-in, and to analyze the relationship between different trajectories and treatment outcomes in tuberculosis patients using data that were generated from smart tools for monitoring their medication adherence and check-in. MethodsFrom October 1, 2022 to September 30, 2023, a total of 163 pulmonary tuberculosis patients diagnosed in Fengxian District were selected as the study subjects. The GBTM was utilized to analyze the weekly active check-in trajectories of the subjects during the first 4 weeks and establish different trajectory groups. The χ² tests were employed to compare the differences between groups and logistic regression analysis was conducted to explore the relationship between different trajectory groups and treatment outcomes. ResultsA total of four groups were generated by GBTM analyses, of which a low level of punch card was maintained in group A, 6% of the drug users increased rapidly from a low level in group B, 17% of drug users increased gradually from a low level in group C, and 18% of drug users maintained a high level of punch card in group D. The trajectory group was divided into two groups according to homogeneity, namely the low level medication punch card group (group A) and the high level medication punch card group (group B, group C, and group D). The results of multivariate logistic regression analyses revealed that low-level medication check-in (OR=3.250, 95%CI: 1.089‒9.696), increasing age (OR=1.030, 95%CI: 1.004‒1.056), and not undergoing sputum examination at the end of the fifth month (OR=2.746, 95%CI: 1.090‒7.009) were significantly associated with poor treatment outcomes. ConclusionThe medication check-in trajectory of pulmonary tuberculosis patients within the first 4 weeks is correlated with adverse outcomes, or namely consistent low-level medication adherence check-ins are associated with poor treatment outcomes, while high-level medication adherence check-ins are associated with a lower incidence of adverse outcomes.

OBJECTIVE To explore the effects and potential mechanism of Huangqi jianzhong decoction on intestinal inflammation in the rats of irritable bowel syndrome with diarrhea (IBS-D) based on the mitogen-activated protein kinase (MAPK)/ nuclear factor-κB (NF-κB) signaling pathway. METHODS Male SD rats were selected. Ten rats were randomly chosen as the control group, and the remaining rats (50 rats) were used to prepare the IBS-D model by acetic acid enema+restraint stress. The rats with successful modeling were randomly divided into the IBS-D group, the traditional Chinese medicine (TCM) group (Huangqi jianzhong decoction 15 g/kg), the positive control drug group (Rifaximin tablets 150 mg/kg), the activator group (anisomycin 125 μg/kg, the activator of p38 MAPK), and the TCM+activator group (Huangqi jianzhong decoction 15 g/kg+ anisomycin 125 μg/kg), with 10 rats in each group. Rats in each group were given a gavage or tail vein injection of the corresponding medicine liquid or the same volume of normal saline, once a day for two consecutive weeks. After the last administration, feces within 24 hours were collected for the calculation of fecal water content and fecal trait score, and the minimum volume threshold was detected. The levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6 in serum were detected; the pathological changes of colonic tissue were observed; the expressions of tight junction protein ZO-1, occludin mRNAs and proteins related to the MAPK/NF- κB signaling pathway in colonic tissue were determined. RESULTS Compared with the control group, obvious edema and inflammatory cell infiltration could be observed in the colonic tissue of rats in the IBS-D group. The fecal water content and trait score, serum levels of inflammatory factors, as well as the protein phosphorylation levels of p38 MAPK and NF-κB p65 in the colonic tissue were significantly increased, while the minimum volume threshold and the mRNA expressions of ZO-1 and occludin were significantly decreased or down-regulated (P<0.05). Compared with the IBS-D group, the pathological changes of colonic tissue in the TCM group and positive control drug group were alleviated, and the above indicators improved significantly (P<0.05), while the above indicators in the activator group deteriorated further (P<0.05). Compared with the TCM group, the above indicators in the TCM+activator group were significantly reversed (P<0.05). CONCLUSIONS Huangqi jianzhong decoction can alleviate colonic inflammation in IBS-D rats, relieve visceral hypersensitivity, and has a certain protective effect on their intestinal barrier function. The above-mentioned effects may be related to the inhibition of the MAPK/NF- κB signaling pathway.

Clinical trials have demonstrated that kilohertz-frequency transcutaneous spinal cord stimulation (TSCS) can be used to facilitate the recovery of sensory-motor function for patients with spinal cord injury, whereas the neural mechanism of TSCS is still undetermined so that the choice of stimulation parameters is largely dependent on the clinical experience. In this paper, a finite element model of transcutaneous spinal cord stimulation was used to calculate the electric field distribution of human spinal cord segments T 12 to L 2, whereas the activation thresholds of spinal fibers were determined by using a double-cable neuron model. Then the variation of activation thresholds was obtained by varying the carrier waveform, the interphase delay, the modulating frequency, and the modulating pulse width. Compared with the sinusoidal carrier, the usage of square carrier could significantly reduce the activation threshold of dorsal root (DR) fibers. Moreover, the variation of activation thresholds was no more than 1 V due to the varied modulating frequency and decreases with the increased modulating pulse width. For a square carrier at 10 kHz modulated by rectangular pulse with the frequency of 50 Hz and the pulse width of 1 ms, the lowest activation thresholds of DR fibers and dorsal column fibers were 27.6 V and 55.8 V, respectively. An interphase delay of 5 μs was able to reduce the activation thresholds of the DR fibers to 20.1 V. The simulation results can lay a theoretical foundation on the selection of TSCS parameters in clinical trials.

The relationship between gut microbiota and depressive disorder has become a research focus in recent years. Within the microbiota-gut-brain axis, the gut microbiota influences the onset and progression of depressive disorder primarily through the tryptophan metabolic pathway. Tryptophan, an essential amino acid in humans, is subject to dual regulation by intestinal microorganisms, which modulate its metabolic balance via inflammatory stimulation and microbial metabolite production. In depression, excessive activation of the kynurenine branch of tryptophan metabolism leads to the accumulation of proinflammatory and neurotoxic metabolites, thereby exacerbating neuroinflammation in the brain. Intervention studies indicate that the antidepressant-like effects of probiotics and traditional Chinese medicine are associated with remodeling of the gut microbiota, restoration of tryptophan metabolic balance, and alleviation of neuroinflammation. Furthermore, targeted inhibition of kynurenine 3-monooxygenase can mitigate neuroinflammation by regulating microglial activity, thus improving depressive-like behaviors. In summary, the metabolite-inflammation axis represents a central node in the interaction regulation between tryptophan metabolism and the microbiota-gut-brain axis. This provides a theoretical foundation for developing novel therapeutic strategies targeting depression through modulation of gut microbiota-mediated tryptophan metabolism.

ObjectiveTo evaluate the effectiveness and safety of neck seven-line method combined with periauricular acupuncture as salvage treatment for sudden hearing loss in non-acute stage. MethodsSixty-six patients with non-acute stage of sudden hearing loss with a disease duration of 15-90 days were randomly divided into 33 cases each in treatment group and control group. The treatment group was given neck seven-line method combined with acupuncture at periauricular points; the control group used sham acupuncture and sham electroacupuncture at the same points. Both groups were treated 3 times a week for 6 weeks. The pure tone average hearing threshold of impaired frequencies were examined before treatment, after treatment finish and at follow-up (week 10), and the difference between pure tone average hearing threshold of impaired frequencies before and after treatment was calculated; calculate the proportion of patients with ≥10 dB improvement in pure tone average hearing threshold of impaired frequency after treatment and at follow-up; compare the patients' Tinnitus Evaluation Scale (TEQ) scores, Chinese Medicine Quality of Life Assessment Scale (CQ-11D) health utility values and the difference between before and after treatment, and record the occurrence of adverse events. ResultsThe pure tone average of impaired frequency in the treatment group were (50.57±18.07) dB and (47.70±17.42) dB at post-treatment and follow-up respectively, and (54.38±21.77) dB and (53.36±20.99) dB in the control group at post-treatment and follow-up. Compared with the pre-treatment period, the pure tone average hearing threshold of impaired frequency in the two groups significantly decreased (P<0.05) at post-treatment and follow-up. The difference of pure tone average hearing threshold of impaired frequency in the treatment group after treatment and at the follow-up visit compared to that before treatment was lower than those in the control group (P<0.05). After treatment, 13 patients (39.39%) in the treatment group and 10 patients (30.30%) in the control group showed improvement of ≥10 dB in pure tone average hearing threshold of impaired frequency; at the follow-up visit, 18 patients (54.55%) in the treatment group and 10 patients (30.30%) in the control group showed improvement of ≥10 dB in the pure tone average hearing threshold of impaired frequency, and there was no statistical significance for comparison between groups at the time of post-treatment and follow-up (P>0.05). The TEQ score of the treatment group significantly lower than that before treatment (P<0.05); the TEQ score of the treatment group and the difference between before and after treatment significantly lower than that of the control group (P<0.05). The difference in CQ-11D health utility values and the difference between before and after treatment were not statistically significant between the two groups (P>0.05). Eight cases of acupuncture-related adverse events occurred among 66 patients, including subcutaneous haematomas after needling, severe pain during needling and needle fainting, which disappeared after symptomatic treatment and did not affect the following treatment. ConclusionNeck seven-line method combined with periauricular acupuncture could be used as salvage treatment for sudden hearing loss in non-acute stage to improve the pure tone average hearing threshold of impaired frequency, alleviate tinnitus, with safety.

Diabetic cognitive dysfunction (DCD) is one of the complications of diabetes, which is characterized by impaired brain structure and progressively decreased learning and memory ability. With the increasing incidence of diabetes worldwide, DCD has become a serious medical and social problem. However, its pathophysiological mechanisms are not well understood. The occurrence and development of DCD involve multiple pathological links and mechanisms, and the prevention and treatment require multi-link and multi-target therapeutic measures. At present, there is no specific drug to prevent or improve DCD. Hypoglycemic drugs such as metformin and vigagliptin or anti-dementia drug including Donepezil are commonly used in clinical treatment to delay the occurrence and progression of cognitive dysfunction, but these drugs have a single target and obvious side effects. Traditional Chinese medicine has a long history in the prevention and treatment of diabetes and central cognitive diseases, and it has many unique advantages such as multiple components, multiple targets, side effects, and low price. A large number of studies have confirmed that traditional Chinese medicine has a significant prevention and treatment effect on DCD, which can improve insulin resistance, synaptic dysfunction, inflammation, oxidative stress, endoplasmic reticulum stress, and neuronal apoptosis by regulating phosphatidylin-ositol 3-kinase (PI3K)/protein kinase B (Akt), advanced glycation end products (AGEs)/advanced glycation end products receptor (RAGE)/nuclear transcription factor-κB (NF-κB), NOD-like receptor thermal protein domain associated protein 3 (NLRP3) inflammasome, and endoplasmic reticulum stress and nuclear factor E2 related factor 2 (Nrf2)/antioxidant response element (ARE) signaling pathways. This article reviewed the effects and related mechanisms of traditional Chinese medicine on DCD in recent years, so as to provide a reference for the prevention and treatment of DCD by traditional Chinese medicine.
