[Objective] To investigate the protective effect of Salvia miltiorrhiza injection (SMI) on the kidneys of HBOC-CHP01 resuscitated haemorrhagic shock rats. [Methods] A 50% haemorrhagic shock rat model was established, with 12 rats divided into two groups: SMI + HBOC-CHP01 group and HBOC-CHP01 group, with 6 rats in each group. The rats in the SMI+ HBOC-CHP01 group were given an equal volume of HBOC-CHP01 for resuscitation after haemorrhagic shock, and an 8 mL/kg dose of SMI. Rats in the HBOC-CHP01 group were resuscitated by administering an equilibrium blood loss volume of HBOC-CHP01 and given an 8 mL/kg dose of 0.9% NaCl solution. Blood was taken from rats at five points: before bloodletting (baseline), during haemorrhagic shock (HS), immediately after resuscitation (RS0h), 1 h after resuscitation (RS1h), and 24 h after resuscitation (RS24h). A blood gas analyser was used to detect the lactate level (Lac), glucose content (Glu), residual base (BEecf), pH, bicarbonate (HCO3-), high iron haemoglobin (MetHb). White blood cells (WBC), platelets (PLT), haemoglobin content (Hb), carboxyhaemoglobin (COHb) were detected using a quintuple classification. Blood creatinine (SCr), uric acid (UA), kidney-related indexes were detected using biochemistry instrument. Kidney tissues of the rats were taken after 24 h of resuscitation and after execution, and the inflammation of kidneys of the rats of the two groups was analyzed using HE staining. Fluorescence staining was used to detect the level of ROS in the kidneys of rats in both groups. [Results] At RS 0h, the Beecf, Glu and Lac levels of rats in the SMI+HBOC-CHP01 group were significantly lower than those of rats in the HBOC-CHP01 group, and the pH level of rats in the SMI+HBOC-CHP01 group was significantly higher than that of rats in the HBOC-CHP01 group, and the Glu levels of rats in the SMI+HBOC-CHP01 group were significantly lower than those of rats in the HBOC-CHP01 group at RS 1h. At RS 0h, the WBC, PLT and COHb contents of rats in the SMI+HBOC-CHP01 group were all significantly higher than those of rats in the HBOC-CHP01 group, and at RS 1h, the WBC content of rats in the SMI+HBOC-CHP01 group was significantly higher than that of rats in the HBOC-CHP01 group; at RS 1h, the UA content of rats in the SMI+HBOC-CHP01 group was significantly lower than that of rats in the HBOC-CHP01 group; at RS 24h, the SCr content of rats in the SMI+HBOC-CHP01 group was significantly lower than that of rats in the HBOC-CHP01 group; at RS 24h, the inflammation level of kidney tissues of rats in the SMI+HBOC-CHP01 group was significantly lower than that of rats in the HBOC -CHP01 group rats, and the ROS and MPO levels in the kidney tissues of rats in the SMI+HBOC-CHP01 group were significantly lower than those of rats in the HBOC-CHP01 group. [Conclusion] The combination of Salvia miltiorrhiza injection during the resuscitation of rats with severe haemorrhagic shock by HBOC-CHP01 can alleviate renal injury by reducing inflammatory response and oxidative stress.

[Objective] To extract hemoglobin (Hb) from red blood cells using osmotic pressure swelling method, expected to achieve a hemoglobin dissolution rate of ≥80% and a cell membrane integrity rate of ≥70%. [Methods] Human umbilical cord blood red blood cells were used as raw materials and phosphate buffer solution was used as the swelling solution for red blood cells. A three factor three-level orthogonal experiment (n=3) was conducted to determine the optimal matching conditions for selecting the osmolality molar concentration of phosphate buffer solution, pH value of hypotonic phosphate buffer solution and volume ratio of hypotonic phosphate buffer solution to washed red blood cells. Red blood cell swelling solution samples (n=6) were prepared by the optimal matching conditions and the original process conditions. The hemoglobin dissolution rate and cell membrane integrity rate were checked. In the expanded comparative experiment, red blood cell swelling solution samples (n=6) were prepared by the optimal matching conditions and the original process conditions, which was filtered by ultrafiltration membranes. The filtration time and hemoglobin yield were checked. [Results] The optimal matching conditions for preparing red blood cell swelling solution were obtained through orthogonal experiment as follows: osmotic pressure molar concentration was 30 mOsmol/Kg, pH was 7.8, and phosphate buffer to red blood cell volume ratio was 6∶1. On the basis of the above conditions, the red blood cell swelling solution sample was compared with the original process sample: the hemoglobin dissolution rate was (82.4±1.8)% vs (78.6±3.0)% (P<0.05), and the cell membrane integrity rate was (65.8±4.0)% vs (28.7±2.3)% (P<0.05). In the expanded comparative experiment, the optimal matching conditions were compared with the original process conditions: filtration time(s) (327±9) vs (434±13) (P<0.05), and hemoglobin yield was (72.3±1.2)% vs (66.0±1.4)% (P<0.05). [Conclusion] Compared with the original preparation process, the hemoglobin extraction process which optimized through orthogonal experiments greatly reduces the cell membrane fragmentation rate and minimizes the entry of cell membrane matrix into the target solution, ensuring a slightly higher hemoglobin dissolution rate, and reducing the preparation difficulty for the subsequent cell membrane separation and further purification.

This article systematically analyzes the historical evolution of the name， origin， quality evaluation， harvesting， processing and other aspects of Picrorhizae Rhizoma by referring to the medical books， prescription books， and other documents of the past dynasties， combined with relevant modern research materials， in order to provide a basis for the development and utilization of famous classical formulas containing this medicinal herb. The research results indicate that Picrorhizae Rhizoma was first recorded in New Revised Materia Medica from the Tang dynasty. Throughout history， Huhuanglian has been used as its official name， and there are also aliases such as Gehu Luze， Jiahuanglian and Hulian. The main source of past dynasties is the the rhizomes of Picrorhiza kurrooa and P. scrophulariiflora. In ancient times， Picrorhizae Rhizoma was mainly imported by foreign traders via Guangzhou and other regions， and also produced in China， mainly in Xizang. In ancient times， it was harvested and dried in early August of the lunar calendar， while in modern times， it is mostly harvested from July to September， with the best quality being those with thick and crispy rhizomes without impurities， and bitter taste. Throughout history， Picrorhizae Rhizoma was collected， washed， sliced， and dried before being used as a raw material for medicine， it has a bitter and cold taste， mainly used to treat bone steaming， hot flashes， infantile chancre fever， and dysentery. There is no significant difference in taste and efficacy between ancient and modern times. Based on the research results， it is recommended that the rhizomes of P. scrophulariiflora in the 2020 edition of Chinese Pharmacopoeia， or the rhizomes of P. kurrooa， can be used in famous classical formulas containing this medicinal herb， which can be processed according to the processing requirements marked by the original formula. For those without clear processing requirements， the dried raw products are used as medicine.

Objective: To study the effect of nano hemoglobin-based oxygen carrier (nano-HBOC) on radiosensitivity of lung cancer H385 cells. Methods: Using 95% N and 5% CO , a lung cancer cell line was constructed in a hypoxic environment, and H385 cells were treated with different concentrations of nano-HBOC and irradiated (4Gy) by an irradiator, and the IC50 concentration was calculated. The cells were detected by flow cytometry (reactive oxygen species, ROS) ROS test. Using GEO database, KEGG pathway enrichment analysis was carried out to predict possible pathways. The levels of lipid peroxidation and Fe were observed by fluorescence microscope, and the proteins related to iron death pathway were detected by Western-blot. Results: Compared with the control cells, the activity and density of the cells were significantly decreased by nano-HBOC combined with radiotherapy, with a notable proportion of cells exhibiting deteriorated status. There is a positive correlation between ROS level and nano-HBOC concentration, especially after radiotherapy. Radiotherapy combined with nano-HBOC significantly increased the levels of lipid peroxidation and Fe in H385 cells, while decreasing the levels of iron death pathway proteins slc7a11 and GPX4, and increasing the level of ACSL4. Conclusion: Nano-HBOC enhances the radiosensitivity of lung cancer H385 cells.

The Department of Thoracic Surgery of Shanghai Chest Hospital has performed esophageal function testing for over 30 years, being the only department of its kind in China with this capability. The pressure testing and 24-hour pH/impedance monitoring of the esophagus is of great help to assist in the diagnosis and treatment of benign and malignant esophageal diseases related to it. Thanks to the esophageal function test, in addition to the routine various endoscopic anti-reflux procedures, our hospital has taken the lead in China in recent years to carry out a series of clinical and research work for benign esophageal diseases, such as the development of magnetic ring, double nedoscopic combination and new anti-reflux endoscopic techniques. In recent years, we have carried out high-resolution esophageal manometry and 24-hour pH/impedance monitoring for patients with interstitial pneumonia and pulmonary fibrosis suspected to be caused by gastroesophageal acid reflux. We can better assess the correlation between gastroesophageal reflux and pulmonary fibrosis, and to provide the different clinical treatments and even surgical interventions. The Bravo capsule is used more often in the United States, and it has obvious advantages over traditional approach for acid measurement. We strongly call for the collaboration between industry and academic institutions in this field, and the development of our own related products with independent intellectual property rights.

OBJECTIVE To explore the willingness to pay （WTP） of Urumqi residents for community pharmacies’ medication guidance services and its influencing factors， so as to provide data support for the optimization of community pharmacy services and the establishment of a fee structure for medication guidance services. METHODS A stratified quota sampling method was employed to select 14 communities in Urumqi City. From April to June 2025， a combined offline and online questionnaire survey was conducted among adult residents in these communities. The contingent valuation method was used to construct three hypothetical scenarios （namely， basic， enhanced and extended services） of medication counselling in community pharmacies to assess residents’ WTP for these services. Binary Logistic regression was employed to analyze the influencing factors of WTP. RESULTS A total of 576 valid questionnaires were obtained. Under the scenarios of basic， enhanced and extended services， 38.54%， 49.65% and 67.19% of the respondents expressed WTP for the services， respectively. Occupational type， type of basic medical insurance， annual income， perception of pharmacists’ profession， and acceptance level of the service were identified as major influencing factors for WTP （P＜0.05）. CONCLUSIONS The willingness of residents in Urumqi to pay for medication counseling services provided by pharmacists in community pharmacies significantly increases with the enrichment of service content. It is recommended to incorporate basic medication counselling services provided by pharmacists in community pharmacies into medical insurance payment， while value-added services should be partially or fully self-paid by residents. Additionally， efforts should be made to strengthen the promotion of the professional and service value of licensed pharmacists， so as to facilitate the high-quality development of pharmaceutical care.

OBJECTIVE To investigate the mechanism by which aloin （ALO） ameliorates atherosclerosis （AS）. METHODS Eight C57BL/6J mice were assigned to the control group （CON group） and fed a standard diet； thirty-two apolipoprotein E-knockout （APOE－/－） mice were randomly divided into model group （MOD group）， ALO low-dose and high-dose groups [ALO-L group， ALO-H group， 20， 40 mg/（kg·d）]， and atorvastatin positive control group [ATO group， 4 mg/（kg·d）]， with 8 mice in each group， establishing the AS model through feeding with a high-fat diet. The mice were administered the drug via gavage or given an equal volume of deionized water for 8 consecutive weeks. The lipid levels in the serum of mice were measured， and the pathological structural changes in their aortas were observed. The expressions of macrophage polarization markers （CD86+ ， CD206+） in the aorta were determined， along with the mRNA expressions of inducible nitric oxide synthase （iNOS）， tumor necrosis factor-α （TNF-α）， arginase-1 （Arg-1）， and interleukin-10 （IL-10）， as well as the protein expressions of iNOS and Arg- 1， and the phosphorylation levels of nuclear factor κB p65 （NF-κB p65） and signal transduction and activator of transcription 3 （STAT3） proteins. Additionally， a macrophage polarization model was established using lipopolysaccharide （LPS）-induced RAW264.7 cells， and the effect of ALO （400 μmol/L） on the cellular polarization phenotype was investigated. RESULTS Compared with the MOD group， administration groups all showed significant improvement in dyslipidemia （except for high-density lipoprotein cholesterol in the serum of ALO-L group） （P＜0.05）； aortic intimal structure improved significantly， plaque area was reduced significantly （P＜0.01）； the CD86+ relative fluorescence intensity in the aorta decreased significantly， the CD206+relative fluorescence intensity increased significantly （P＜0.01）， while the expressions of iNOS and TNF-α mRNA were down-regulated significantly （P＜0.05）； mRNA expressions of Arg-1 and IL-10， and protein expression of Arg-1 were increased significantly in ALO-H group and ATO group （P＜0.05）； the protein expressions of iNOS， and the phosphorylation levels of NF-κB p65 and STAT3 protein were decreased significantly （P＜0.05）. In vitro experiments further confirmed that ALO significantly reduced the proportion of LPS-induced M1-type macrophages but increased the proportion of M2-type macrophages （P＜0.01）. CONCLUSIONS ALO inhibits M1-type macrophage polarization and promotes M2-type polarization， ameliorates dyslipidemia and reduces arterial plaque formation in AS model mice， improve the structure of the aortic intima potentially through suppression of the NF-κB/STAT3 signaling pathway.

Objective To investigate the relationship between serum high mobility group protein B1(HMGB1),C1q/TNF-associated protein 3(CTRP3)and pain degree and lumbar function.Methods A total of 145 patients with lumbar spinal stenosis treated in the hospital from September 2021 to August 2023 were retrospectively selected as the study objects,and were divided into single-segment group(89 cases)and multi-segment group(56 cases)according to the number of lumbar spinal stenosis segments.Serum levels of HMGB1 and CTRP3 were detected by enzyme-linked immunosorbent assay.The clinicopathological features such as pain degree,lumbar function and serum levels of HMGB1 and CTRP3 were compared between the two groups.The correlation of serum HMGB1 and CTRP3 levels with pain degree and lumbar function were ana-lyzed,and the factors influencing the number of segments of lumbar stenosis were analyzed by multivariate Logistic regression.The diagnostic value of serum HMGB1 and CTRP3 levels on lumbar function of patients was analyzed by receiver operating characteristic(ROC)curve.Results Visual analogue scale(VAS)score and serum HMGB1 level in multi-segment group were higher than those in single-segment group(P＜0.05),Japanese Orthopaedic Association(JOA)score and serum CTRP3 level were lower than those in single-seg-ment group(P＜0.05).Serum HMGB1 level was negatively correlated with CTRP3 and JOA score in pa-tients with lumbar spinal stenosis(r=-0.544,-0.616,P＜0.001),and positively correlated with VAS score(r=0.453,P＜0.001).The serum CTRP3 level was negatively correlated with VAS score(r=-0.550,P＜0.001),and positively correlated with JOA score(r=0.619,P＜0.001).JOA score was nega-tively correlated with VAS score(r=-0.485,P＜0.001).Multivariate Logistic regression analysis showed that JOA score and serum CTRP3 level were protective factors for multi-segmental stenosis(P＜0.05),VAS score and serum HMGB1 level were risk factors for multi-segmental stenosis(P＜0.05).The analysis of ROC curve showed that serum HMGB1 and CTRP3 levels could be used as diagnostic indexes of lumbar spinal function in patients with lumbar spinal stenosis,and the combined diagnosis effect was better(P＜0.05).Conclusion Serum levels of HMGB1 and CTRP3 are closely related to pain degree and lumbar function in pa-tients with lumbar spinal stenosis.The combination of the two indexes can be used for the clinical diagnosis of lumbar function in patients with lumbar spinal stenosis.
