Objective:To optimize the preparation process of Qinggan Liangxue Granules.Methods:The L 9 (3 4) orthogonal experimental design was used to investigate the effects of water addition, extraction time and extraction times on the extraction process of Qinggan Liangxue Granules by taking the transfer rate of astilbin and paeoniflorin as the indexes, so as to screen the optimal extraction process. The evaluation indexes of granule molding rate, water content, solubility and fluidity were used to compare the effect of finished products under different ratios of excipients and granulation conditions. Results:The optimal extraction process was to add 10 times the amount of water reflux extraction twice, each time 1.5 h; using wet granulation, the ratio of dry paste powder to base material was 4:1 ( m/ m), and the wetting agent was 95% ethanol. Conclusion:The preparation process of Qinggan Liangxue Granules is stable and feasible, which lays a foundation for further research and development and quality control.

Objective:To investigate the impacts of fatty acid binding protein 4(FABP4)silencing on endoplasmic reticulum stress(ERS)and insulin resistance(IR)in gestational diabetes mellitus(GDM)rats by regulating protein kinase R-like endoplasmic reticulum kinase(PERK)/eukaryotic initiation factor 2α(eIF2α)/transcription factor 4(ATF4)/C/EBP homologous protein(CHOP)signaling pathway.Methods:GDM rat model was established by intraperitoneal injection of streptozotocin(STZ).Rats were injected with FABP4 siRNA plasmid(si-FABP4),negative control plasmid(NC)and PERK activator(CCT020312)via tail vein,and were randomly grouped into Normal group,GDM group,GDM+NC group,GDM+si-FABP4 group and GDM+si-FABP4+CCT020312 group.The levels of FABP4,blood lipids,inflammatory markers and oxidative stress markers in pancreatic tissue were detected,the expres-sions of PERK/eIF2α/ATF4/CHOP signaling pathway-related proteins in pancreatic tissue were detected.HTR-8/SVneo cells were divided into 5 groups:Control group,high glucose(HG)group,HG+NC group,HG+si-FABP4 group,HG+si-FABP4+CCT020312 group.After 24 h,the expressions of FABP4 and PERK/eIF2α/ATF4/CHOP signaling pathway related proteins were detected.Results:Compared with Normal group,the level of FABP4 in the serum and pancreatic tissue of the GDM group were obviously up-regu-lated(P<0.05).FABP4 silencing obviously reduced FBG and IR,decreased the levels of blood lipids,CRP,TNF-α,IL-6 and MDA,and increased the levels of SOD and CAT(P<0.05).Furthermore,FABP4 silencing attenuated pancreatic and placental tissue damages.After CCT020312 up-regulated the phosphorylation levels of PERK and eIF2α and the protein expressions of ATF4 and CHOP,the inhibitory effects of FABP4 silencing on IR,inflammation,oxidative stress,and pancreatic and placental damages in GDM rats were reversed(P<0.05).FABP4 was up-regulated in HTR-8/SVneo cells induced by HG,and silencing FABP4 inhibited the protein ex-pression of the PERK/eIF2α/ATF4/CHOP pathway,while CCT020312 reversed this change(P<0.05).Conclusion:FABP4 silencing improves IR and ERS in GDM rats by inhibiting inflammation and oxidative stress,and the mechanism is related to the inhibition of PERK/eIF2α/ATF4/CHOP signaling pathway.

Objective To explore the clinical value of laparoscopic radical cystectomy based on fascia anatomy for bladder cancer treatment.Methods The clinical data of 51 patients with bladder cancer who underwent 3D laparoscopic radical cystectomy during Jan.2015 and Jun.2022 were retrospectively analyzed.The surgery was performed based on membrane anatomy technology along four longitudinal and two transverse planes to complete the radical cystectomy.The pelvic plexus was preserved for patients with normal preoperative sexual function.Results All surgeries were completed without conversion to open operation.The mean operation time was(502.52±108.99)min,mean intraoperative blood loss was(275.96±155.18)mL,mean postoperative drainage time was(4.14±2.41)d,and the mean postoperative hospital stay was(16.37±4.85)d.The mean number of lymph nodes removed was(17.98±11.48).The mean postoperative follow-up was(30.27±19.39)months.At the last follow-up,no Clavien ≥grade 3 complications were observed.The estimated overall survival(OS),tumor-specific survival(TSS),and recurrence-free survival(RFS)were 82.4％,92.2％,and 88.2％,respectively.The lymph node positive patients had shorter OS and RFS(60.0％,60.0％)than the lymph node negative patients(84.8％,91.3％).Among the 19 male patients who underwent radical cystectomy with pre-exposure and preservation of pelvic plexus,daytime and nocturnal continence rate were 83.3％and 72.2％,respectively,and 17 patients recovered potency within 6 months postoperatively.Conclusion Laparoscopic radical cystectomy based on fascia anatomy is safe and effective in laparoscopic radical cystectomy,with standardized surgical procedure,satisfactory oncological outcomes,little hemorrhage,few complications and fast recovery.

Background/Aims: The shortage of donor liver hinders the development of liver transplantation. This study aimed to clarify the poor outcomes of functionally marginal liver grafts (FMLs) and provide evidence for the improvement of ischemia-free liver transplantation (IFLT) after FML transplantation. Methods: Propensity score matching was used to control for confounding factors. The outcomes of the control group and FML group were compared to demonstrate the negative impact of FMLs on liver transplantation patients. We compared the clinical improvements of the different surgical types. To elucidate the underlying mechanism, we conducted bioinformatic analysis based on transcriptome and single-cell profiles. Results: FMLs had a significantly greater hazard ratio (HR: 1.969, P=0.018) than did other marginal livers. A worse 90-day survival (Mortality: 12.3% vs. 5.0%, P=0.007) was observed in patients who underwent FML transplantation. Patients who received FMLs had a significant improvement in overall survival after IFLT (Mortality: 10.4% vs 31.3%, P=0.006). Pyroptosis and inflammation were inhibited in patients who underwent IFLT. The infiltration of natural killer cells was lower in liver grafts from these patients. Bulk transcriptome profiles revealed a positive relationship between IL-32 and Caspase 1 (R=0.73, P=0.01) and between IL-32 and Gasdermin D (R=0.84, P=0.0012). Conclusions FML is a more important negative prognostic parameter than other marginal liver parameters. IFLT might ameliorate liver injury in FMLs by inhibiting the infiltration of NK cells, consequently leading to the abortion of IL-32, which drives pyroptosis in monocytes and macrophages.

ObjectiveTo investigate the effect of anodal transcranial direct current stimulation (atDCS) combined with contralaterally controlled functional electrical stimulation (CCFES) on upper limb motor function of stroke patients. MethodsFrom January to December, 2022, 60 stroke patients from Zhejiang Provincial People's Hospital were randomly divided into atDCS group (n = 20), CCFES group (n = 20) and combined group (n = 20). All the groups accepted routine rehabilitation, while atDCS group accepted atDCS on the primary motor (M1) area of the damaged hemisphere, CCFES group accepted CCFES on the triceps brachii and extensors carpi muscles, and the combined group accepted atDCS on the M1 area of damaged hemisphere and CCFES on triceps brachii and extensors carpi muscles, for six weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Wolf Motor Function Test (WMFT), and the electromyography root mean square (RMS) ratio of bilateral triceps brachii muscles and extensor carpi muscles, before and after treatment. ResultsThe FMA-UE score, WMFT score, and the RMS ratio of the triceps brachii muscles and extensor carpi muscles improved in all the groups after treatment (|t| > 5.007, P < 0.001), and improved the most in the combined group (F > 14.492, P < 0.001). ConclusionatDCS combined with CCFES can effectively improve upper limb motor function of stroke patients.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

OBJECTIVE To understand the current status of research on traditional Chinese medicine（TCM） human resources， and to provide a reference for expanding research ideas on TCM human resources and promoting the construction of TCM talents. METHODS From January 1， 2000 to December 31， 2022， literature related to TCM human resources was collected from the three major databases of CNKI， Wanfang and VIP. Using CiteSpace 5.8 R3 software， visualization analysis was performed for the literature in terms of publication time， journal sources， authors， institutions and areas， funding， research content， keywords， etc. RESULTS A total of 324 literature related to TCM human resources in China were included， and the number of literature issued showed an upward trend， with an annual average of 14.09 literature； 161 kinds of journals were involved， core journals accounted for 18.21% of the total publication volume； a total of 23 authors had published 2 or more literature， with a total of 55 literature published （16.98%）； a total of 416 institutions were involved， mainly schools （66.83%）； 60.49% of the literature were supported by the fund. The majorities of 324 literature were survey studies （170 literature）， and most of them used self-designed questionnaires （55 literature）； the high-frequency keywords included talent training， human resources， TCM， etc. The keywords were clustered into 7 categories， such as “human resources“”talent training“”TCM industry“”TCM services“”talent training models” “fairness” and “TCM talents”. The main problems described in the literature included insufficient talent， lack of reasonable distribution of regional structure， lack of reasonable plans for talent training， and insufficient professional knowledge and abilities. Continuously cultivating high-level talents and improving employment conditions in areas with severe human resource loss were the corresponding countermeasures proposed in the literature. CONCLUSIONS The research on TCM human resources starts late but has developed rapidly overall， and the quality of research needs to be improved； the structure of research team is single and unevenly distributed geographically； there is a structural imbalance in the allocation of human resources， as well as problems such as a shortage of professional talents， low levels of education and training and incomplete development systems.

Post-amputation pain causes great suffering to amputees, but still no effective drugs are available due to its elusive mechanisms. Our previous clinical studies found that surgical removal or radiofrequency treatment of the neuroma at the axotomized nerve stump effectively relieves the phantom pain afflicting patients after amputation. This indicated an essential role of the residual nerve stump in the formation of chronic post-amputation pain (CPAP). However, the molecular mechanism by which the residual nerve stump or neuroma is involved and regulates CPAP is still a mystery. In this study, we found that nociceptors expressed the mechanosensitive ion channel TMEM63A and macrophages infiltrated into the dorsal root ganglion (DRG) neurons worked synergistically to promote CPAP. Histology and qRT-PCR showed that TMEM63A was mainly expressed in mechanical pain-producing non-peptidergic nociceptors in the DRG, and the expression of TMEM63A increased significantly both in the neuroma from amputated patients and the DRG in a mouse model of tibial nerve transfer (TNT). Behavioral tests showed that the mechanical, heat, and cold sensitivity were not affected in the Tmem63a^-/- mice in the naïve state, suggesting the basal pain was not affected. In the inflammatory and post-amputation state, the mechanical allodynia but not the heat hyperalgesia or cold allodynia was significantly decreased in Tmem63a^-/- mice. Further study showed that there was severe neuronal injury and macrophage infiltration in the DRG, tibial nerve, residual stump, and the neuroma-like structure of the TNT mouse model, Consistent with this, expression of the pro-inflammatory cytokines TNF-α, IL-6, and IL-1β all increased dramatically in the DRG. Interestingly, the deletion of Tmem63a significantly reduced the macrophage infiltration in the DRG but not in the tibial nerve stump. Furthermore, the ablation of macrophages significantly reduced both the expression of Tmem63a and the mechanical allodynia in the TNT mouse model, indicating an interaction between nociceptors and macrophages, and that these two factors gang up together to regulate the formation of CPAP. This provides a new insight into the mechanisms underlying CPAP and potential drug targets its treatment.

Objective:To analyze the psychological contract satisfaction of contracted residents and its impact on their behavioral intentions under the guidance of incomplete contract theory, for reference in improving the effectiveness of contracted family doctor services.Methods:1 100 contracted residents from nine townships/streets in Shandong province were selected as subjects according to stratified random sampling from September 2019 to June 2020, and a questionnaire survey on the level of satisfaction of contracted residents′ psychological contracts(24 items) and assessment of behavior intentions(9 items) was conducted, and the model of the effect of contracted residents′ psychological contracts on behavior intentions was established and analyzed. The correlation was validated by Pearson test and the structural equation method was used for verifying the model.Results:998 valid questionnaires were recovered. The psychological contract satisfaction score of the contracted residents was 3.45±0.56 and the behavioral intention was 2.81±0.29. Both transactional and relational psychological contracts were correlated with all dimensions of behavioral intention( P<0.01). Concerning the impacts of residents′ psychological contracts on behavioral intentions, the effect coefficients of transactional psychological contracts on loyalty intention, voice intention, exit intention and neglect intention were 0.33, 0.24, -0.25 and -0.49 respectively, with an indirect effect on neglect intention; the effect coefficients of relational psychological contracts on loyalty intention, voice intention, exit intention and neglect intention were 0.26, 0.10, -0.14 and -0.50 respectively, with an indirect effect on advice intention and neglect intention. Conclusions:Residents′ psychological contract has yet not been effectively satisfied. Satisfying and improving the residents′ psychological contract can directly enhance their loyalty intention and reduce their exit intention, indirectly influencing the voice and neglect intentions. In order to enhance the effectiveness of family doctor contracted services and improve the healthcare experience of contracted residents, it is suggested that the relevant departments should actively take the following measures, including carrying out a survey on the psychological contract of contracted residents, building a provincial-city-county-township collaborative linkage platform, and so on.
