OBJECTIVE To investigate the use of drugs and the development of pharmaceutical care in the tight medical alliance (shorted for “medical alliance”) of Wanzhou District of Chongqing, and provide reference for the further construction of the medical alliance. METHODS A survey form was designed and distributed to 21 constituent units (5 leading units and 16 member units) of 5 medical alliances in Wanzhou District of Chongqing. The statistical analysis was conducted in aspects of basic drug allocation and use, pharmaceutical personnel team construction, the development of pharmaceutical care, and rational use of antibiotics. RESULTS Among the 21 constituent units, 4 leading units and 14 member units achieved the target for the proportion of essential drug procurement varieties, with a total compliance rate of 85.71%; 4 leading units and 13 member units achieved the target for the proportion of national essential drug allocation and usage amount, with a total compliance rate of 80.95%. The proportions of personnel with doctoral degrees in the 5 leading units and 16 member units were 1.71% and 0 respectively, and the proportions of personnel with senior professional titles were 8.56% and 1.63%, respectively. A total of 5 pharmacy or pharmaceutical combined outpatient clinics were set up in the 21 medical alliance units, and 5 clinical pharmacy information service platforms were established; all 5 leading units were able to regularly carry out clinical pharmacy projects, while only 4 out of 16 member units had conducted medical order review and evaluation. The proportions of irrational use of antibiotics in outpatient prescriptions and inpatient medical records of the 16 member units (4.81%, 5.21%) were significantly higher than those of the 5 leading units (2.80%, 4.00%). CONCLUSIONS The allocation and usage of national essential drugs in 21 constituent units from Wanzhou District of Chongqing are both in good standing. However, the data on the allocation of pharmaceutical professionals and the number, qualifications, and job titles of clinical pharmacists in member units are generally low. Moreover, the pharmaceutical service projects and service quality in member units need to be further improved.

ObjectiveTo investigate the analgesic effect of Tuina at the "Weizhong (BL 40)" on neuropathic pain in a rat model of chronic constriction injury (CCI) of the sciatic nerve and its potential central spinal mechanisms. MethodsThirty-two Sprague-Dawley rats were randomly divided into four groups (8 rats in each group), sham-operated group, model group, Tuina group, and blockade group. The CCI model was established in the model group, Tuina group, and the blockade group by ligating the sciatic nerve with catgut, while the sham-operated group underwent only sciatic nerve exposure without ligation. From postoperative day 4 to day 14, rats in the Tuina group and the blockade group received Tuina manipulation at the "Weizhong (BL 40)" using a dynamic pressure distribution measurement system (5 N pressure, 2 Hz frequency, 10 min per session, once daily). The blockade group also received intraperitoneal injections of the microglial inhibitor minocycline (10 mg/kg) once daily. The sham-operated and the model group underwent the same handling and fixation as the Tuina group without actual Tuina. Mechanical withdrawal threshold (MWT) and paw withdrawal latency (PWL) were measured before surgery and on day 3, 7, 10, and 14 post-surgery. Transmission electron microscopy was used to evaluate sciatic nerve injury and repair, measuring axon diameter and total myelinated fiber diameter to calculate the g-ratio. Western Blotting was performed to detect the protein levels of ionized calcium-binding adapter molecule 1 (Iba-1), CD206, CD68, interleukin-10 (IL-10), and β-endorphin (β-EP) precursor pro-opiomelanocortin (POMC) in the ipsilateral spinal dorsal horn. ResultsCompared with the sham-operated group, the model group showed significantly reduced MWT and PWL on day 3, 7, 10, and 14 (P<0.01). Compared with the model group, the Tuina group and the blockade group showed increased MWT and PWL on day 10 and 14 (P<0.05). Compared with the Tuina group, the blockade group exhibited higher MWT on day 7, 10, and 14, and higher PWL on day 10 (P<0.05). Sciatic nerve pathological morphology revealed intact and well-structured myelin in the sham-operated group, while the model group exhibited myelin collapse, distortion, and myelin ovoid formation. The Tuina group displayed partially irregular myelin with occasional myelin collapse, whereas the blockade group exhibited partial myelin irregularities and phospholipid shedding. Compared with the sham-operated group, the model group showed a decreased g-ratio and increased levels of Iba-1 and CD68 in the spinal dorsal horn (P<0.05 or P<0.01). Compared with the model group, the Tuina group and the blockade group exhibited an increased g-ratio and reduced Iba-1 and CD68 levels. Additionally, the Tuina group showed elevated levels of CD206, IL-10, and POMC, whereas the blockade group had decreased CD206 levels (P<0.05). ConclusionTuina at "Weizhong (BL 40)" alleviates neuropathic pain in CCI rats, potentially by regulating microglial activation in the spinal cord, inhibiting M1 polarization while promoting M2 polarization, and activating the IL-10/β-EP pathway to exert analgesic effects.

ObjectiveTo investigate the effects of Xijiao Dihuangtang (XJDHT) on mice with sepsis and cellular models of sepsis and explore its molecular mechanism in alleviating sepsis-induced inflammatory responses via regulating pyruvate kinase M2 (PKM2)-mediated one-carbon metabolism pathway. MethodsForty C57BL/6N mice were randomly divided into four groups: normal group, model group, low-dose XJDHT group (7.7 g·kg-1), and high-dose XJDHT group (15.4 g·kg-1). After one week of continuous gavage, sepsis was induced using cecal ligation and puncture (CLP) in groups except the normal group. 24 h after the surgery, mortality rates in all groups were recorded, and serum cytokines were measured by enzyme linked immunosorbent assay (ELISA). Lung histopathology was examined by hematoxylin-eosin (HE) staining. During the in vitro experiment, the human monocytic leukemia cell line (THP-1) was exposed to various concentrations of XJDHT and treated with lipopolysaccharide (LPS) at a final concentration of 2 mg·L-1 for 24 h. Cell apoptosis was detected using terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Protein levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), B-cell lymphoma 2 (Bcl-2), and Bcl-2-associated X protein (Bax) were measured by Western blot. Transcriptome sequencing was performed to analyze differentially expressed genes in all groups and conduct gene ontology (GO) enrichment. Key genes in the one-carbon metabolism pathway, including pyruvate kinase M2 (PKM2), 5-methyltetrahydrofolate-homocysteine methyltransferase (MTR), and phosphoglycerate dehydrogenase (PHGDH), were verified by Western blot. A PKM2 inhibition model was established using shikonin for further protein expression analysis. ResultsAnimal experiments showed that compared with the normal group, the model group exhibited significantly elevated body temperature and lung pathology (P<0.01) and increased serum TNF-α and IL-1β levels (P<0.01). High-dose XJDHT reduced body temperature and lung tissue damage (P<0.01) and significantly decreased serum TNF-α and IL-1β levels (P<0.01). Low-dose XJDHT treatment showed no significant temperature change (P<0.01) but reduced serum TNF-α and IL-1β levels (P<0.01). Transcriptome sequencing and Western blot revealed significant differences in the expression of TNF-α, IL-1β, and one-carbon metabolism genes (PKM2, MTR, and PHGDH) (P<0.01). Cell experiments demonstrated that compared to the normal group, the model group showed elevated protein expressions of TNF-α and IL-1β in THP-1 cells (P<0.01), decreased Bcl-2/Bax ratio, and increased apoptosis (P<0.01). Transcriptome sequencing and Western blot revealed significant differences in the expression of TNF-α, IL-1β, and one-carbon metabolism genes (PKM2, MTR, and PHGDH) (P<0.01). Compared to the model group, high-dose XJDHT significantly increased Bax/Bcl-2 ratio and PHGDH protein expression (P<0.01) and effectively reduced cell apoptosis (P<0.01) while down-regulating protein expressions of TNF-α, IL-1β, PKM2, and MTR (P<0.01). Low-dose XJDHT moderately increased Bax/Bcl-2 ratio and PHGDH protein expression (P<0.05), reduced apoptosis (P<0.05), and decreased IL-1β and MTR protein levels (P<0.05, P<0.01), but there were no significant changes in TNF-α and PKM2 expression. After PKM2 inhibition by shikonin in THP-1 cells, the expression of protein related to one-carbon metabolism was detected. Compared with the blank group, the LPS-induced model group showed significantly upregulated PKM2 and MTR protein expression (P<0.01) and downregulated PHGDH expression (P<0.01). Compared with the model group, shikonin treatment significantly reduced PKM2 expression (P<0.05), increased PHGDH expression (P<0.01), and decreased MTR expression (P<0.05). ConclusionXJDHT can inhibit the release of inflammatory factors in sepsis, and its mechanism is related to the intervention of the PKM2-regulated one-carbon metabolism pathway in macrophages.

BACKGROUND:Multiple studies have confirmed that mitogen-activated protein kinase(MAPK)signaling pathway is involved in cell proliferation,and microRNA(miR)is involved in the occurrence and development of hypertrophic scars.Therefore,the role of miR-27a-3p and MAPK signaling pathways in pathological scar formation has been further explored. OBJECTIVE:To explore the effect of miR-27a-3p on the proliferation of human hypertrophic scar fibroblasts through the MAPK signaling pathway. METHODS:The primary fibroblasts were isolated and collected from the skin samples.The primary fibroblasts were observed by inverted microscope and verified by immunofluorescence.The relative expression level of miR-27a-3p in tissues was detected by qRT-PCR.The target genes of hsa-miR-27a-3p were predicted using the database,and then the predicted target genes were enriched by gene ontology function analysis and biological pathway enrichment analysis of the Kyoto Encyclopedia of Genes and Genomes.There were seven groups:blank control,negative control,miR-27a-3p mimic,miR-27a-3p inhibitor,miR-27a-3p mimic+p38 MAPK inhibitor,miR-27a-3p mimic+extracellular regulated protein kinase inhibitor,miR-27a-3p mimic+c-Jun N-terminal kinase inhibitor.Western blot was used to detect the levels of extracellular regulated protein kinase,c-Jun N-terminal kinase inhibitor.and p38 kinase and their phosphorylation levels.Cell counting kit-8 and EdU were used to detect cell proliferation. RESULTS AND CONCLUSION:Compared with normal skin fibroblasts,hypertrophic scar fibroblasts had stronger proliferative activity(P<0.05)and faster proliferation level(P<0.001).Compared with normal skin,miR-27a-3p was highly expressed in hypertrophic scars(P<0.001).Compared with the negative control group,overexpression of miR-27a-3p could promote cell proliferation activity(P<0.001)and proliferation levels(P<0.001).Compared with the negative control group,knockdown of miR-27a-3p could inhibit the proliferation activity(P<0.05)and proliferation levels(P<0.001).Compared with the negative control group,overexpression of miR-27a-3p promoted the phosphorylated levels of extracellular regulated protein kinase,c-Jun N-terminal kinase,and p38 mitogen-activated protein kinase(P<0.05).Compared with the negative control group,knockdown of miR-27a-3p inhibited the phosphorylated levels of extracellular regulated protein kinase,c-Jun N-terminal kinase,and p38 MAPK(P<0.05).Compared with the miR-27a-3p mimic group,specific inhibitors of extracellular regulated protein kinase,c-Jun N-terminal kinase,and p38 MAPK reversed the effects of miR-27a-3p on the proliferative activity(P<0.01)and proliferation level(P<0.001)of fibroblasts.To conclude,these results suggest that miR-27a-3p promotes the proliferation of human hypertrophic scar fibroblasts by activating the MAPK signaling pathway.

Journal of Traditional Chinese Medicine 2025;66(10):1057-1059
It is believed that the basic mechanism of cough associated with interstitial lung disease is collaterals deficiency with latent wind: the deficiency of the lung organs and lung collaterals is the basis of its pathogenesis, and latent wind in lung collaterals is the key mechanism of the cough which is difficult to cure. Treatment is based on the principle of supplementing deficiency and treating wind, dispelling the pathogens and unblocking the collaterals. Supplementing deficiency should supplement lungs, boost kidneys, and strengthen spleens to consolidate the root and banking up the origin, and regulate and tonify the lung collaterals; dispelling the pathogens should treat the internal and external winds at the same time, and taking into account the combined pathogens of phlegm, stasis and dampness to clear the stagnation of the lung collaterals.

Background:
Intraoperative hypercapnia reduces the time to emergence from volatile anesthetics, but few clinical studies have explored the effect of hypercapnia on the emergence time from intravenous (IV) anesthesia. We investigated the effect of inducing mild hypercapnia during the recovery period on the emergence time after total IV anesthesia (TIVA).
Methods:
Adult patients undergoing transurethral lithotripsy under TIVA were randomly allocated to normocapnia group (end-tidal carbon dioxide [ETCO2] 35–40 mmHg) or mild hypercapnia group (ETCO2 50-55 mmHg) during the recovery period. The primary outcome was the extubation time. The spontaneous breathing-onset time, voluntary eye-opening time, and hemodynamic data were collected. Changes in the cerebral blood flow velocity in the middle cerebral artery were assessed using transcranial Doppler ultrasound.
Results:
In total, 164 patients completed the study. The extubation time was significantly shorter in the mild hypercapnia (13.9 ± 5.9 min, P = 0.024) than in the normocapnia group (16.3 ± 7.6 min). A similar reduction was observed in spontaneous breathing-onset time (P = 0.021) and voluntary eye-opening time (P = 0.008). Multiple linear regression analysis revealed that the adjusted ETCO2 level was a negative predictor of extubation time. Middle cerebral artery blood flow velocity was significantly increased after ETCO2 adjustment for mild hypercapnia, which rapidly returned to baseline, without any adverse reactions, within 20 min after extubation.
Conclusions
Mild hypercapnia during the recovery period significantly reduces the extubation time after TIVA. Increased ETCO2 levels can potentially enhance rapid recovery from IV anesthesia.
