ObjectiveTo systematically compare the differential regulation of the maternal-fetal interface cell lineages and communication networks in the CBA/J×DBA/2 mouse model of recurrent pregnancy loss （RPL） by the two classic therapeutic methods-tonifying the kidney to stabilize the fetus and invigorating the spleen to stabilize the fetus （Shoutai Wan， Juyuan Jian）-of traditional Chinese medicine （TCM） at the single-cell resolution and clarify their modern scientific connotations. MethodsFemale non-pregnant CBA/J mice were caged with male BALB/c （blank group） and DBA/2 （modeling group） mice separately. Pregnant mice in the modeling group were randomly grouped as follows： high/low-dose Shoutai Wan， high/low-dose Juyuan Jian， model （RPL）， and positive control （dydrogesterone）， with 10 mice in each group. Starting from the day after the detection of the vaginal plug， mice were administrated with drugs or an equal volume of normal saline by gavage for 10 consecutive days. After the intervention， the following indicators were measured. ① Macroscopic evaluation： general conditions， uterine wet weight， embryo loss rate， four coagulation parameters ［prothrombin time （PT）， activated partial thromboplastin time （APTT）， fibrinogen （FIB）， and thrombin time （TT）］， and peripheral blood estradiol （E₂） and progesterone （Pg） levels. The decidua with embryos was stained with hematoxylin-eosin （HE） and evaluated by transmission electron microscopy （TEM）. The expression of B-cell lymphoma-2 （Bcl-2）， vascular endothelial growth factor （VEGF）， angiotensin Ⅱ （AngⅡ）， matrix metalloproteinase-2 （MMP-2）， interleukin-6 （IL-6）， leukemia inhibitory factor （LIF）， CXC chemokine ligand 12 （CXCL12）， and microtubule-associated protein 1 light chain 3 homolog （LC3）Ⅰ/Ⅱ was quantified by Western blot. ② Mechanism analysis at the single-cell level： The decidua with embryos from the blank， model， high-dose Shoutai Wan， and high-dose Juyuan Jian groups （6 mice per group， with 3 single-cell samples per group， totaling 24 mice） were analyzed by the BD Rhapsody™ platform， and the whole-cell atlas was drawn by uniform manifold approximation and projection （UMAP） dimensionality reduction clustering combined with the single-cell mouse cell atlas （scMCA）. The differentially expressed genes （DEGs） and cell interaction networks were analyzed via Gene Ontology （GO）， Kyoto Encyclopedia of Genes and Genomes （KEGG）， and CellChat， and the protein-protein interaction （PPI） map of subtype cells was constructed. The CytoTRACE pseudo-temporal analysis was performed to explore the developmental trajectories of core immune cells （natural killer cells， NK cells） from maternal and fetal sources. Results① Pathological and Western blot results indicated that compared with the blank group， the RPL group showed an increase in the embryo loss rate （P<0.01）， down-regulated expression of Bcl-2， LIF， MMP-2， and Vegf in the decidua with embryos （P<0.05）， up-regulated protein levels of CXCL-12， AngⅡ， and IL-6 （P<0.05）， blocked angiogenesis， apoptosis-inflammation imbalance， and coagulation dysfunction. Both prescriptions dose-dependently reduced the abortion rate and restored the angiogenesis-inflammation balance， and Shoutai pill showed superior performance in restoring the E₂ level to the Pg level （P<0.05）. ② Single-cell transcriptome analysis indicated that compared with the blank group， the RPL group showed differences in multiple key cell populations such as decidual cells， trophoblast cells， endothelial cells， erythroblasts， NK cells， and macrophages at the maternal-fetal interface. Immunity and angiogenesis were the key links in RPL. Compared with the RPL group， high-dose Shoutai Wan reversed the changes of NK cells in the embryonic layer （upregulating the mRNA levels of 17 genes and downregulating the mRNA levels of 29 genes） and macrophages （upregulating the mRNA levels of 117 genes and downregulating the mRNA levels of 53 genes） through the regulation of gene expression. High-dose Shoutai pill regulated the immune cells to affect unfolded proteins， cell adhesion， and programmed cell death， thereby promoting decidualization and angiogenesis and modulating embryo-membrane development. High-dose Juyuan Jian regulated the key subgroups of NK cells （up-regulating the mRNA levels of 9 genes and down-regulating the mRNA levels of 17 genes） and macrophages （up-regulating the mRNA levels of 110 genes and down-regulating the mRNA levels of 81 genes）， which affected decidual inflammation and apoptosis and intervened in glycolysis. ③ The pseudo-temporal analysis and communication network indicated that the communication frequency of the RPL group decreased. High-dose Shoutai Wan restored maternal-fetal tolerance through pathways such as NKG2D， CDH5， GDF， and FASLG. High-dose Juyuan Jian enhanced the IL-6/LIFR/JAK/signal transducer and activator of transcription 3 （STAT3） and desmosome/SEMA6/tumor necrosis factor-like weak inducer of apoptosis （TWEAK） signaling to improve endometrial receptivity. The RPL group showed an increased proportion of toxic dNK7， a decreased proportion of reparative dNK4， and blocked embryo fNK1. High-dose Shoutai Wan down-regulated dNK7 and up-regulated dNK4. High-dose Juyuan Jian inhibited the terminal differentiation of dNK7 and up-regulated LILRB1， thus restoring the balance of cytotoxicity and repair. ConclusionBoth the kidney-tonifying and spleen-invigorating methods are effective in treating RPL. NK and macrophages are the key immune cells in the interaction between the embryo and the membrane. The kidney-tonifying method （Shoutai Wan） has an advantage in regulating the phenotypes of unfolded protein， cell adhesion， and programmed cell death， and shows expression characteristics closer to the physiological state in the regulation of NKG2D and CDH5 signals. The spleen-invigorating method （Juyuan Jian） has an advantage in regulating epithelial-mesenchymal transition （EMT）， angiogenesis， and glycolysis and shows higher communication intensity in the IL-6 and LIFR pathways.

After kidney transplantation,the recipients have been under long-term immunosuppression due to the use of immunosuppressive drugs,and they are high-risk population of Pneumocystis jirovecii pneumonia(PJP).The risk of PJP is the highest within 6 months after kidney transplantation and after intensified anti-rejection therapy.Fever,dry cough,progressive dyspnea and hypoxemia are common clinical manifestations of PJP after kidney transplantation.Trimethoprim-sulfamethoxazole(TMP-SMX)can effectively prevent and treat PJP,and significantly reduce the incidence rate and fatality of PJP.To standardize the diagnosis,treatment and prevention of PJP after kidney transplantation,Branch of Organ Transplantation of Chinese Medical Association organized relevant Chinese experts to formulate the"Guidelines for Clinical Diagnosis and Treatment of Pneumocystis Jirovecii Pneumonia After Kidney Transplantation in China"based on clinical concerns,aiming to provide guidance for the prevention and comprehensive clinical treatment of PJP after kidney transplantation.

Objective To analyze the application characteristics of acupuncture and moxibustion in the treatment of postherpetic neuralgia(PHN)using complex networks;To provide clinical acupuncture and moxibustion treatment with application basis for acupoint selection,acupuncture and moxibustion,and treatment ideas.Methods The clinical research literature on acupuncture and moxibustion treatment for PHN was retrieved from CNKI,Wanfang Data,VIP,PubMed and Web of Science.The literature was screened according to the inclusion and exclusion criteria,and Excel 2019 was used to establish an acupuncture and moxibustion treatment PHN database.SPSS Modeler 18.0 software was used for modeling and association rule analysis,and Gephi 0.10.1 software was used for complex network analysis.Results Totally 237 articles were included,and 262 acupuncture and moxibustion prescriptions data were extracted,involving a total of 115 acupoints,with a total use frequency of 1 432 times.The top 10 most frequently used acupoints were Ashi acupoint(214 times)and Jiaji acupoint(198 times),Zusanli(74 times),Taichong(74 times),Sanyinjiao(66 times),Hegu(65 times),Yanglingquan(62 times),Xuehai(60 times),Zhigou(53 times),and Quchi(52 times).The association rule analysis showed that the acupoint combination with the highest correlation was Ashi acupoint-Jiaji acupoint.K-core hierarchical analysis and community analysis on the complex network of the acupoint prescriptions obtained two core acupoint groups.Therapy analysis showed that filiform needle acupuncture was the most commonly used intervention for acupuncture treatment of PHN;syndrome type-acupoint analysis showed that the syndrome types with the highest frequency of PHN were liver meridian heat stagnation,blood stasis and collaterals obstruction,and spleen meridian damp-heat;tonic and diarrhea-acupoint analysis showed that the main operating techniques were neutral-tonifying and neutral-discharging.Conclusion Acupuncture and moxibustion treatment for PHN mainly selects local acupoints,Ashi acupoint and Jiaji acupoint are often selected,and focusing on the cooperation with distal acupoints.The external and internal meridians are mostly selected according to different syndrome types.The operation is performed using neutral-tonifying and neutral-discharging techniques.Commonly used filiform acupuncture combined with electro-acupuncture,pricking,cupping and other therapies.The application characteristics can provide clinical reference for the treatment of PHN.

The included literature was summarized and analyzed.Results:A total of 43 articles were included, consisting of 16 cross-sectional surveys, 8 qualitative studies, and 19 intervention studies. Five aspects were elaborated and summarized, namely theoretical evolution and development, evaluation tools, current situation and influencing factors, implementation approaches, and intervention program characteristics.Conclusions:The research on self-transcendence in cancer patients is in the ascendant. In the future, it is necessary to strengthen the development of self-transcendence assessment tools for cancer patients, adopt various research methods to comprehensively understand the changes in self-transcendence level and psychological experience of cancer patients, and improve the scientific and rigorous nature of self-transcendence intervention program for cancer patients.

Objective To assess short-and long-term changes in the upper airway,natural head position and hyoid bone position in skeletal Class Ⅲ patients after bimaxillary surgery.Methods In this retrospective study,the cone-beam computed tomography(CBCT)of skeletal Class Ⅲ patients was taken before surgery(T0),3 months after surgery(T1)and 2 years after surgery(T2).Three-dimensional images were created to assess postoperative changes and the correlation between the upper airway,natural head posi-tion and hyoid bone was analyzed.Results Thirty skeletal Class Ⅲ patients(13 men and 17 women)who underwent bimaxillary sur-gery with a mean(SD)age of 21 years(a range of 17-30 years)were evaluated.A significant decrease was observed in the volume of palatopharynx,glossopharynx and total airway after T1 and T2.There was a significant correlation between changes in the position of the mandible and changes in the volume of the upper airway(P＜0.05).The NSL/OPT angle and the NSL/CVT angle were greater after Tl and T2.The change in the NSL/CVT angle was positively correlated with the change in palatopharyngeal and glossopharyngeal volume(P＜0.05).Conclusion Bimaxillary surgery may cause a decrease in upper airway volume,an increase in the cranio-cervical angle,and a downward and backward movement of the hyoid bone.Changes in the cranio-cervical angle may cause changes in the upper air-way.

OBJECTIVE To investigate the implementation effects of the national centralized drug volume-based procurement policy （abbreviated as “national centralized procurement policy”） in Guangxi Zhuang Autonomous Region prefecture， and to provide a reference for the future centralized drug procurement work of the medical institution. METHODS Drug procurement data before and after policy implementation were included in the study. The six secondary indicators （such as availability， affordability， and drug safety） and eighteen third-level indicators （such as completion rate of agreed purchase volume， affordability level， drug revenue proportion） were introduced， guided by the policy objectives and issues of concern to policy beneficiaries. Descriptive statistics was adopted to analyze the data before and after policy implementation （in 2019 and 2020） in terms of differences and change trends. RESULTS In terms of accessibility， the participation rate of medical institutions in Guangxi Zhuang Autonomous Region was 92.55%， the proportion of diseases involved and median completed procurement rate were 40.16%， and 287.82% respectively， and the total centralized delivery rate was 97.20%. In terms of affordability， the total reduction amplitude in drug price was 74.80% from 2019 to 2022； the charge for medicine per capita in hospitalization， the proportion of medicine used for outpatient service and hospitalization， decreased by 17.61%， 10.22%， and 20.10% in order； the burden levels on medical fares for patients were all below 1 in addition to chronic diseases， and anti-tumor drugs. In terms of the impact on medicine， the ratio of adverse drug reaction event cases in 2022 was 66.00%， an increase of 1.29% compared to the previous； since the implementation of the policy， 12 drugs from local pharmaceutical enterprises from Guangxi Zhuang Autonomous Region had passed the consistency evaluation， and the market concentration rate of the top 8 pharmaceutical companies was less than 20.00%. In terms of the impact on healthcare and medical insurance， the public medical institutions achieved generic substitution for originator drugs mostly until 2022； about 9.12% of drugs that were non- centrally purchased in the same category were used； 63.39% of people under investigation did not show a need for a second dressing change； drug expenditure decreased by 2.459 billion yuan. CONCLUSIONS The national centralized procurement policy achieves a significant effect in Guangxi Zhuang Autonomous Region. On the other hand， attention should be paid to these suggestions as follows: expanding the category of drugs used in clinic， conducting clinically comprehensive evaluation of selected drugs， and improving reasonable allocation strategy， etc.

Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.

Objective To identify the characteristics of complementary and alternative therapies for cancer patients and investigate the effect on symptom clusters in cancer patients,in order to provide references in management of the symptom clusters.Methods A scoping review was conducted to search nine databases,namely PubMed,Cochrane Library,Web of Science,Embase,PsycINFO,CINAHL,CNKI,Wanfang Data,and VIP,for literatures published between January 2016 and January 2024.Results Twenty articles focusing on complementary and alternative therapies were included.Four themes were identified from the retrieved articles:cancer research subjects,characteristics of complementary alternative therapies,type of symptom cluster and effectiveness of complementary alternative therapies.Specifically,the cancer research subjects in relation to symptom cluster management included those of breast cancer,advanced cancer and the cancer under radio or chemotherapy.The most commonly used types of complementary and alternative therapies in managing the symptom clusters were exercise therapies,cognitive-behavioural interventions,traditional Chinese medicine therapies,multidisciplinary collaborative models and specific interventions.Interventions for symptom clusters predominantly targeted fatigue,mental status,pain,and gastrointestinal symptoms.Conclusion The interventions for symptom clusters in complementary and alternative therapies vary across different types of complementary and alternative therapies,so as the effectiveness.Some of the complementary and alternative therapies have unidentified effects and further investigations are required.The complementary and alternative therapies currently that have been used in managing the symptom clusters were found to have shortcomings.Further studies should focus on sentinel and core symptoms of symptom clusters and emphasize the development of standardised and individualised intervention plans based on symptom management theories,hence to improve the management of symptom clusters in cancer patients.

OBJECTIVE To evaluate the efficacy of the functional dressing of Polygonum capitatum nanofibers （P-PVP-PCL）. METHODS P-PVP-PCL were prepared by electrospinning technology， and the microstructure of P-PVP-PCL was observed. The antibacterial activity and antioxidant activity of P-PVP-PCL and its effects on the survival rate， adhesion and migration rate of mouse fibroblast L929 cells were investigated. The effects of medical gauze dressing， blank nanofiber dressing （PVP-PCL） and P- PVP-PCL on the healing rate of the wound were investigated by establishing the back skin wound model of rats. The pathological changes of the wound tissue and collagen fiber deposition were observed， as well as the number of platelet endothelial cell adhesion molecule-1 （CD31） positive blood vessels and the expression of transforming growth factor-β （TGF-β） protein in wound tissue. RESULTS P-PVP-PCL had a smooth surface and a double-layer structure at the cross-section. The inhibition rates of P-PVP-PCL against Staphylococcus aureus and Escherichia coli were （98.88±0.66）% and （94.75±1.41）% ， respectively. The antioxidant activity of P-PVP-PCL was （83.69±1.56）%， and the cell activity of the P-PVP-PCL group was significantly higher than those of the control group and PVP-PCL group （P＜0.05）. Compared with medical gauze dressings， P-PVP-PCL was more conducive to L929 cell adhesion； at 48 hours， the cell scratches in this group had basically healed. Compared with the medical gauze dressing group， the wound healing rates of the PVP-PCL group and the P-PVP-PCL group were significantly increased （P＜0.05）. On the 14th day of intervention， the wounds in the P-PVP-PCL group had basically healed， there was no dermal necrosis in the wound tissue， and the collagen fibers were arranged relatively neatly and the density was relatively uniform. The number of CD31 positive blood vessels and the expression of TGF-β protein showed a downward trend compared with the 7th day of intervention， and the number of CD31 positive blood vessels was significantly lower than those of the medical gauze dressing group and PVP-PCL group （P＜0.05）， but the protein expression of TGF- β was significantly higher than those of the medical gauze dressing group and the PVP-PCL group （P＜0.05）. CONCLUSIONS P-PVP-PCL has good antibacterial and antioxidant activity in E-mail：444096585@qq.com vitro， and can promote the proliferation， adhesion and migration of L929 cells. It can promote wound healing of rats in vivo.
