ObjectiveTo compare the differences between wild Alpiniae Oxyphyllae Fructus(WAOF) and cultivated Alpiniae Oxyphyllae Fructus(CAOF) through a traditional quality evaluation system for medicinal materials. MethodsA total of 10 batches of WAOF and 12 batches of CAOF samples were collected from various regions of Hainan province. Relevant analytical methods from the 2020 edition of the Pharmacopoeia of the People's Republic of China were employed to observe the characteristics of WAOF and CAOF, followed by microscopic identification, thin-layer chromatography(TLC) identification, moisture content(toluene method), total ash, acid-insoluble ash, water-soluble and alcohol-soluble extracts(hot dipping method), water-soluble protein, total polysaccharides and total flavonoids(ultraviolet spectrophotometry), and volatile oil content(method A under general rule 2204). The contents of five active components(protocatechuic acid, chrysin, kaempferol, tectochrysin and nootkatone) were quantified using ultra-performance liquid chromatography(UPLC), and the antioxidant activity was evaluated. Building upon traditional quality evaluation of AOF, quantitative measurements were conducted on its appearance traits including diameter, length, plumpness(diameter/length ratio), and color. Canonical correlation analysis was performed using SPSS 26.0 to explore relationships between appearance traits and intrinsic quality. ResultsNo significant differences were observed between WAOF and CAOF in microscopic observation, TLC identification, moisture content, protocatechuic acid content, kaempferol content, odor, or antioxidant activity measured by 2,2ʹ-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS) method. WAOF exhibited significantly higher levels in water-soluble extracts, alcohol-soluble extracts, total polysaccharide content, water-soluble protein content, 100-grain weight, length, and total color difference(ΔE*ab) compared to CAOF(P<0.01). In contrast, CAOF showed significantly higher levels of total ash, acid-insoluble ash, content of total flavonoids, volatile oil content, chrysin content, tectochrysin content, nootkatone content, diameter, plumpness, lightness(L*), red-green chromaticity(a*), yellow-blue chromaticity(b*), and antioxidant activity measured by 1,1-diphenyl-2-picrylhydrazyl(DPPH) method compared to WAOF(P<0.01). Correlation analysis between 7 phenotypic traits and 8 quality traits revealed that among the phenotypic traits, plumpness, L*, a*, and b* exerted significant influence on intrinsic quality. Among the quality traits, total flavonoids, volatile oils, nootkatone, chrysin, and tectochrysin contributed substantially to intrinsic quality. ConclusionPlumpness, L*, a*, and b* of AOF significantly influence its intrinsic quality, and higher values of these parameters indicate relatively superior intrinsic quality. The comprehensive quality evaluation reveals that CAOF samples collected in this study are superior to their wild counterparts.

Through consulting herbal medicine, medical books, and local chronicles from past dynasties to modern times, this paper systematically researched Spatholobi Caulis from name, origin, producing areas, harvesting, processing, usage, quality evaluation, functions and indications, providing a reference for the development and utilization of famous classical formulas containing Spatholobi Caulis. According to the research, Spatholobi Caulis was first recorded in the Annals of Shunning Prefecture from the Qing dynasty. It was originally a medicinal herb commonly used in Shunning, Yunnan, and was named from the red juice resembling chicken blood that flowed out after the vein was cut off. The mainstream original plants of each dynasty were Kadsura heteroclita and Spatholobus suberectus. Among them, K. heteroclita mainly focused on dispersing blood stasis and unblocking meridians, mainly treating rheumatic pain and injuries caused by falls or blows, and it is mostly used as the raw material of Jixueteng ointments. S. suberectus was commonly used as decoction pieces in decoction, which had the functions of promoting blood circulation and replenishing blood, activating meridians and collaterals, and mainly used for treating anemia, irregular menstruation, and rheumatic bone pain. The production area of Spatholobi Caulis recorded in the Qing dynasty was Yunnan. Currently, the main production area of S. suberectus is Guangxi, while the main production area of K. interior is Yunnan. In the Qing dynasty, the usage of Spatholobi Caulis was an individual prescription with other herbs before making ointments, which was usually composed of the juice of it, safflower, angelica, and glutinous rice. But in modern times, Spatholobi Caulis is mostly sliced and dried for use. The quality of Spatholobi Caulis is often determined by the number of reddish-brown concentric circles on the cut surface, with a higher number indicating better quality. Additionally, the presence of resinous secretions is also considered desirable. Based on the research findings, it is suggested that when developing famous classical formulas containing Spatholobi Caulis, the choice of the primary source should be S. suberectus or K. heteroclita, taking into consideration the therapeutic effects of the formula. It is also recommended that the latest plant classification be referenced in the next edition of Chinese Pharmacopoeia, adjusting the primary source of Kadsurae Caulis to K. heteroclita to avoid confusion caused by inconsistent original names, and the functions adjust to promote Qi circulation and relieve pain, disperse blood stasis and unblock collaterals, treating injuries caused by falls and bruises.

BACKGROUND:Cervical disc herniation can cause pain in the neck and shoulder area,as well as radiating pain in the upper limbs.The incidence rate is increasing year by year and tends to affect younger individuals.Fully understanding the biomechanical characteristics of the cervical spine in adolescents is of great significance for preventing and delaying the onset of cervical disc herniation in this age group. OBJECTIVE:To reconstruct cervical spine models for both healthy adolescents and adolescent patients with cervical disc herniation utilizing finite element analysis techniques,to analyze the motion range of the C1-T1 cervical vertebrae as well as the biomechanical characteristics of the annulus fibrosus,nucleus pulposus,endplates,and the cartilage of the small joints. METHODS:A normal adolescent's cervical spine and an adolescent patient with cervical disc herniation were selected in this study.The continuous scan cervical spine CT raw image data were imported into Mimics 21.0 in DICOM format.The C1-T1 vertebrae were reconstructed separately.Subsequently,the established models were imported into the 3-Matic software for disc reconstruction.The perfected models were then imported into Hypermesh software for meshing of the vertebrae,nucleus pulposus,annulus fibrosus,and ligaments,creating valid geometric models.After assigning material properties,the final models were imported into ABAQUS software to observe the joint motion range of the C1-C7 cervical vertebrae segments under different conditions,and to analyze the biomechanical characteristics of the annulus fibrosus,nucleus pulposus,endplates,and small joint cartilage of each cervical spine segment. RESULTS AND CONCLUSION:(1)In six different conditions,the joint motion range of the C1 vertebra in the cervical spine models of both normal adolescent and adolescent patient with cervical disc herniation was higher than that of the other vertebrae.Additionally,the joint motion range of each cervical spine segment in normal adolescent was greater than that in adolescent patient with cervical disc herniation.(2)In the cervical spine model of normal adolescent,the maximum stress values in the annulus fibrosus and nucleus pulposus were found on the left side during C2-3 flexion conditions(0.43 MPa and 0.17 MPa,respectively).In the cervical spine model of adolescent patient with cervical disc herniation,the maximum stress values were found on the left side during C7-T1 flexion conditions(0.54 MPa and 0.18 MPa,respectively).(3)In the cervical spine model of normal adolescent,the maximum stress value on the endplate was found on the left side of the upper endplate of C3 during flexion conditions(1.46 MPa).In the model of adolescent patient with cervical disc herniation,the maximum stress value on the endplate was found on the left side of the lower endplate of C7 during flexion conditions(1.32 MPa).(4)In the cervical spine model of normal adolescent,the maximum stress value in the small joint cartilage was found in the C2-3 left rotation conditions(0.98 MPa).In adolescent patient with cervical disc herniation,the stress in the small joint cartilage significantly increased under different conditions,especially in C1-2,with the maximum stress found during left flexion(3.50 MPa).(5)It is concluded that compared to normal adolescent,adolescent patient with cervical disc herniation exhibits altered cervical curvature and a decrease in overall joint motion range in the cervical spine.In adolescent with cervical disc herniation,there is a significant increase in stress on the annulus fibrosus,nucleus pulposus,and endplates in the C7-T1 segment.The stress on the left articular cartilage of the C1-2 is notable.Abnormal cervical curvature may be the primary factor causing these stress changes.

Objective: To investigate the positive rate of drug-induced antibodies produced by the clinical application of β-lactam antibiotics, and analyze the differences in the detection methods and related influencing factors. Methods: A total of 350 adult inpatients who developed anemia after using β-lactam antibiotics for 3 days or more in Inner Mongolia People's hospital were selected as the experimental group, and 240 adult inpatients treated with β-lactam antibiotics for 3 days or more who did not develop anemia as the control group. The drug-induced antibody tests, direct antiglobulin tests, and unexpected antibody screening were performed on both groups, and the influencing factors of drug-induced antibodies were analyzed. Results: The numbers of positive cases of drug-induced antibody detected by the drug-coated red blood cell method in the experimental group and the control group were 12(12/350, 3.43%) and 2(2/240, 0.83%) respectively, with statistically significant differences (P<0.05). No drug-induced antibodies were detected in either group using the drug addition method. In the experimental group, the red blood cell method detected β-lactam drug-induced antibodies in 12 cases (12/350, 3.43%), while the drug added method detected 0 cases (0/350, 0.00%), with statistically significant differences (P<0.05). In the control group, the detection rates of two methods showed no statistically significant difference (P>0.05). In the experimental group, 7 cases of β-lactam antibodies were detected in the cephalosporin group (7/293, 2.40%) and 5 cases in the non-cephalosporin group (5/58, 8.62%), with statistically significant differences (P<0.05). There was no statistically significant difference between the second-generation and third-generation cephalosporin drugs (P>0.05). When the experimental group was stratified according to the history of blood transfusion and the blood type of patients, no statistically significant differences were observed between subgroups (P>0.05). Conclusion: Anemia may be related to the production of drug-induced antibodies followingβ-lactam antibiotics treatment. Therefore, improving the clinical awareness of drug-induced antibodies to β-lactam antibiotics is of great significance to clarify the causes of anemia and reduce unnecessary blood transfusions.

OBJECTIVE To assess the cost-effectiveness of durvalumab combined with chemotherapy as a first-line treatment for advanced biliary tract cancer from the perspective of the Chinese healthcare system. METHODS Using data from the TOPAZ-1 clinical trial, a three-state Markov model comprising progression-free survival (PFS), progressive disease (PD) and death was developed, with a cycle length of 21 days and a 10-year time horizon. Patients in the observation group received durvalumab in combination with gemcitabine and cisplatin, whereas those in the control group received placebo plus the same chemotherapy regimen. The evaluation indexes were quality-adjusted life year (QALY) and the incremental cost-effectiveness ratio (ICER). The willingness-to-pay (WTP) threshold was set at three times the 2024 Chinese per capita gross domestic product (GDP) (287 247 yuan/QALY). The sensitivity analyses, along with scenario analyses, were performed. RESULTS In the base-case analysis, the ICER of observation group compared to control group was 1 166 344.46 yuan/QALY, far exceeding the WTP threshold, indicating that the regimen was not cost-effective. One-way sensitivity analysis identified the PD state utility, discount rate, cost of durvalumab, and PFS state utility as the main drivers of ICER variation. Probabilistic sensitivity analysis showed that, at the above WTP threshold, the probability of the acceeptance of this regimen was 0, further supporting the robustness of the base-case findings. In the scenario analysis, inclusion of a patient assistance program reduced the ICER to 235 885.16 yuan/ QALY, below the above WTP threshold, suggesting cost-effectiveness under this assistance program. However, when applying a regional WTP threshold set at three times the per capita GDP (158 475 yuan/QALY) of Gansu Province (the province with the lowest GDP in China in 2024), the ICER remained above the threshold, indicating that the regimen was not cost-effective at the regional level. CONCLUSIONS At current pricing, durvalumab plus chemotherapy as a first-line treatment for advanced biliary tract cancer is not cost-effective in China. Although the introduction of a patient assistance program can substantially reduce the ICER and achieve cost-effectiveness at a WTP threshold set at three times the 2024 per capita GDP of China, due to limited affordability in low-income areas, the program remains not cost-effective.

This paper presents an automatic acquisition and analytic procedure of acupuncture manipulation based on optical navigation, aiming at solving the shortcomings of existing acquisition methods of acupuncture manipulation. An acquisition holder installed at the handle tail of filiform needle was designed to display the movement trajectory of the needle during acupuncture delivery by collecting the movement trajectory of holder. The 3-month old male Bama miniature pig was selected as the experimental subject, and 6 points, "Bojian" "Qiangfeng" "Housanli" "Xiaokua" "Huiyang" (BL35) and "Baihui" (GV20), were selected during acupuncture manipulation. The optical navigation system was used to collect the real-time data, and these data were per-processed and analyzed using mean filtering and Fourier transform. The acupuncture procedure was divided into 3 stages, inserting, lifting-thrusting, and twisting. The results showed that the accuracy was 96.3% at lifting-thrusting stage, and that was 100.0% at twisting stage. The decomposition effect of the entire procedure was satisfactory. This study provides a new approach to the quantitative analysis of acupuncture manipulation. In the future, it needs to further optimize the algorithm and expand the sample size so as to improve the accuracy of this analytic technique.

Objective:To explore the clinical effects of tibial periosteal distraction combined with antibiotic bone cement in treating diabetic foot ulcer.Methods:The study was a retrospective observational study. From March 2021 to March 2024, 52 patients with diabetic foot ulcers who met the inclusion criteria were admitted to Gansu Provincial People's Hospital, including 25 males and 27 females, aged 34-77 years. According to the treatment methods used by the patients, they were divided into control group (22 cases) treated with antibiotic bone cement alone and combined group (30 cases) treated with tibial periosteal distraction combined with antibiotic bone cement. Toe amputation rate, limb amputation rate, length of hospitalization, and ulcer healing time-consuming of patients were recorded. Before the first treatment and 3 weeks after the last treatment, the ankle skin temperature and ankle-brachial index of the affected foot were measured routinely, the pain of the affected foot was evaluated by using visual analog scale (VAS), and the peripheral nerve function of the affected foot was evaluated by 10 g nylon thread examination (denoted as 10 g nylon thread test value). Three weeks after the last treatment, the clinical efficacy of patients was evaluated and the overall rate of clinical efficacy was calculated.Results:There were no statistically significant differences in the comparison of toe amputation rate and limb amputation rate of patients in the 2 groups ( P>0.05). The length of hospitalization and ulcer healing time-consuming of patients in combined group were (23±5) and (41±6) d, respectively, which were significantly shorter than (27±5) and (46±6) d in control group (with t values of 3.08 and 3.18, respectively, both P values <0.05). The ankle skin temperature of the affected foot of patients in combined group was (34.1±1.5) ℃, and the ankle-brachial index was 0.72±0.08 three weeks after the last treatment, which were significantly higher than (32.1±1.6) ℃ and 0.58±0.09 before the first treatment within the group (with t values of 5.10 and 6.37, respectively, P<0.05) and (31.8±1.1) ℃ and 0.59±0.09 three weeks after the last treatment in control group (with t values of 6.88 and 5.49, respectively, P<0.05). The pain VAS score of the affected foot of patients in combined group 3 weeks after the last treatment was significantly lower than that before the first treatment within the group and 3 weeks after the last treatment in control group (with t values of 8.16 and 6.83, respectively, both P values <0.05), and the 10 g nylon thread test value was significantly higher than that before the first treatment within the group and 3 weeks after the last treatment in control group (with t values of 6.15 and 4.23, respectively, both P values <0.05). Three weeks after the last treatment, the overall rate of clinical efficacy of patients in combined group was 96.7% (29/30), which was significantly higher than 63.6% (14/22) in control group, χ2=7.51, P<0.05. Conclusions:Tibial periosteal distraction combined with antibiotic bone cement has good clinical effects in the treatment of diabetic foot ulcers. It can shorten the length of patients' hospitalization, promote the healing of the ulcers, reduce the pain in the affected foot, and improve the blood supply and peripheral nerve function in the affected foot.
9.Application progress of histological scores in disease activity assessment of inflam-matory bowel disease
Chinese Journal of Clinical and Experimental Pathology 2025;41(7):929-934
The histological assessment has been considered as a detailed and accurate method for measuring the disease activity in inflammatory bowel disease(IBD).In ulcerative colitis(UC),histological activity has been demon-strated to be associated with a higher rate of relapse,prolonged corticosteroid use and long-term complications,even in patients who have achieved endoscopic remission.Therefore,histological remission may be regarded as a potential ther-apeutic target.This article introduces the clinical significance of disease activity assessment in IBD,focusing on the re-view of validated and newly proposed histological scoring systems for IBD,and explores the priorities for future research needs.

Objective:To investigate the clinical characteristics of cervical adenocarcinoma and analyze the survival status and related prognostic factors.Methods:The data of 229 patients with cervical adenocarcinoma who were diagnosed pathologically in the General Hospital of Ningxia Medical University from January 2013 to October 2022 were retrospectively analyzed. Among them, 198 early stage patients were mainly treated with surgery, and 31 locally advanced stage patients were mainly treated with chemoradiotherapy. The overall survival (OS) and progression-free survival (PFS) rates in the whole cohort of patients and different treatment subgroups were calculated. Kaplan‐Meier method and log‐rank test were used for survival analysis, and Cox proportional hazards model was used for univariate and multivariate survival analyses.Results:Among the 229 patients, there were 11 subtypes of pathological classifications, predominantly of the usual‐type. At the end of follow‐up, 57 patients (24.9%) relapsed. The 3‐ and 5‐year OS rates were 86.4% and 79.3%, respectively, and the 3‐ and 5‐year PFS rates were 81.6% and 73.6%, respectively. Multivariate analysis showed that International Federation of Gynecology and Obstetrics (FIGO) staging of stages Ⅲ‐Ⅳ was an independent prognostic factor for OS and PFS ( HR=2.033, 95% CI=1.456‐2.839, P<0.001; HR=1.701, 95% CI=1.251‐2.313, P=0.001). Lymph node metastasis was an independent risk factor for PFS ( HR=1.610,95% CI=1.021‐2.539, P=0.041). Subgroup analysis of 198 patients with surgical treatment: the 3‐ and 5‐year OS rates were 90.0% and 84.9%, and the 3‐ and 5‐year PFS rates were 82.7% and 76.7%, respectively. Multivariate analysis showed that lymph node metastasis and deep invasion depth were the main risk factors for OS ( HR=6.893, 95% CI=2.592‐18.327, P<0.001; HR=1.952, 95% CI=1.164‐3.272, P=0.011) and PFS ( HR=5.507, 95% CI=2.569‐11.805, P<0.001; HR=1.638, 95% CI=1.09‐2.461, P=0.018). Ovarian preservation was an independent risk factor for PFS ( HR=3.364, 95% CI=1.115‐10.151, P=0.031). Conclusions:The pathological types of cervical adenocarcinoma are complex and diverse. Local recurrence and distant metastasis are the main reasons for treatment failure. FIGO stage, lymph node metastasis and postoperative depth of invasion are the main prognostic factors of cervical adenocarcinoma.
