Objective:To observe the effects of warming triple needling plus Chinese medication on inflammatory responses and daily functioning ability in patients with knee osteoarthritis(KOA)due to wind-cold-dampness Bi-impediment. Methods:A total of 101 patients with KOA due to wind-cold-dampness Bi-impediment were divided into an acupuncture-medication group and a Chinese medication group using the random number table method.Fifty cases in the Chinese medication group took oral Fang Feng Xi Bi Tang for treatment,and 51 cases in the acupuncture-medication group received additional warming triple needling therapy.The symptom score of traditional Chinese medicine(TCM),inflammatory factor levels,and motor function of the knee joint were compared before and after treatment.The clinical efficacy was also compared between the two groups after treatment. Results:Three cases in the acupuncture-medication group and 2 cases in the Chinese medication group dropped out during the study,and the two groups each had 48 cases being included in statistical analysis ultimately.The total effective rate was 95.8%in the acupuncture-medication group,higher than 79.2%in the Chinese medication group,and the between-group difference was statistically significant(P<0.05).After treatment,the TCM symptom score dropped in both groups(P<0.05)and was lower in the acupuncture-medication group than in the Chinese medication group(P<0.05).The levels of interleukin(IL)-6,tumor necrosis factor(TNF)-α,and IL-1β dropped after the intervention in both groups(P<0.05)and were lower in the acupuncture-medication group than in the Chinese medication group(P<0.05).The scores of knee pain intensity,knee joint stiffness,and diurnal functioning decreased after treatment in the two groups(P<0.05)and were lower in the acupuncture-medication group than in the Chinese medication group(P<0.05). Conclusion:Warming triple needling plus Fang Feng Xi Bi Tang can reduce inflammatory responses,improve daily functioning ability,and enhance the quality of life in patients with KOA due to wind-cold-dampness Bi-impediment.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To observe the clinical efficacy of body acupuncture combined with FANG's scalp acupuncture in treating limb dysfunction in the remission stage of stroke and explore the mechanism. Methods:Sixty patients in the remission stage of stroke with limb dysfunction were divided into a control group and a treatment group using the random number table method,with 30 cases in each group.The control group was treated with ordinary acupuncture based on the conventional rehabilitation treatment,and the treatment group was additionally offered FANG's scalp acupuncture.The interventions were conducted once daily with 10 sessions as 1 course.The Fugl-Meyer assessment(FMA)and Barthel index(BI)scores and serum malondialdehyde(MDA)and superoxide dismutase(SOD)levels were compared after 2 treatment courses,and the clinical efficacy was evaluated. Results:After treatment,the FMA and BI scores increased in both groups(P<0.05)and were higher in the treatment group than in the control group(P<0.05).Both groups showed a decreased MDA level and an increased SOD level after the intervention,all showing statistical significance(P<0.05);there were significant differences between the two groups(P<0.05). Conclusion:Based on the conventional rehabilitation treatment,ordinary acupuncture used alone or in combination with FANG's scalp acupuncture can lower the oxidative stress level and improve limb function in treating limb dysfunction in the remission stage of stroke;body acupuncture plus FANG's scalp acupuncture can produce better results.

This study aimed to investigate the mechanism of resveratrol(RES) combined with irinotecan(IRI) in the treatment of colorectal cancer(CRC). The targets of RES, IRI, and CRC were obtained from databases, and the targets of RES combined with IRI in the treatment of CRC were acquired by Venn diagram. The protein functional cluster analysis, GO and KEGG enrichment analyses were performed. In addition, the protein-protein interaction(PPI) network was constructed. The core target genes were screened out and the target-signaling pathway network was set up. IGEMDOCK was used to dock the core target gene molecules. Besides, the relationship between the expression level of key target genes and the prognosis and immune infiltration of CRC was analyzed. Based on the in vitro cell experiment, the molecular mechanism of RES combined with IRI in the treatment of CRC was explored and analyzed. According to the results, 63 potential targets of RES combined with IRI were obtained for CRC treatment. Furthermore, cluster analysis revealed that protein functions included 23% transmembrane signal receptors, 22% protein modifying enzymes, and 14% metabolite converting enzymes. GO analysis indicated that BPs were mainly concentrated in protein autophosphorylation, CCs in receptor complex and plasma membrane, and MFs in transmembrane receptor protein tyrosine kinase activity. Moreover, KEGG signaling pathways were mainly enriched in central carbon metabolism in cancer. The key targets of RES combined with IRI in the treatment of CRC were PIK3CA, EGFR, and IGF1R, all of which were significantly positively correlated with the immune infiltration of CRC. As shown by the molecular docking results, PIK3CA had the most stable binding with RES and IRI. Compared with the results in the control group, the proliferation ability and EGFR protein expression of CRC cells in the RES-treated group, the IRI-treated group, and the RES+IRI treated group significantly decreased. Moreover, the cell proliferation ability and EGFR protein expression level of CRC cells in the RES+IRI treated group were remarkably lower than those in the IRI-treated group. In conclusion, PIK3CA, EGFR, and IGF1R are the key targets of RES combined with IRI in CRC treatment. In addition, RES can inhibit the proliferation of CRC cells and improve IRI chemoresistance by downregulating the EGFR signaling pathway.

Objective: Total neoadjuvant therapy has been used to improve tumor responses and prevent distant metastases in patients with locally advanced rectal cancer (LARC). Patients with complete clinical responses (cCR) then have the option of choosing a watch and wait (W&W) strategy and organ preservation. It has recently been shown that hypofractionated radiotherapy has better synergistic effects with PD-1/PD-L1 inhibitors than does conventionally fractionated radiotherapy, increasing the sensitivity of microsatellite stable (MSS) colorectal cancer to immunotherapy. Thus, in this trial we aimed to determine whether total neoadjuvant therapy comprising short-course radiotherapy (SCRT) combined with a PD-1 inhibitor improves the degree of tumor regression in patients with LARC. Methods: TORCH is a prospective, multicenter, randomized, phase II trial (TORCH Registration No. NCT04518280). Patients with LARC (T3-4/N+M0, distance from anus ≤10 cm) are eligible and are randomly assigned to consolidation or induction arms. Those in the consolidation arm receive SCRT (25Gy/5 Fx), followed by six cycles of toripalimab plus capecitabine and oxaliplatin (ToriCAPOX). Those in the induction arm receive two cycles of ToriCAPOX, then undergo SCRT, followed by four cycles of ToriCAPOX. Patients in both groups undergo total mesorectal excision (TME) or can choose a W&W strategy if cCR has been achieved. The primary endpoint is the complete response rate (CR, pathological complete response [pCR] plus continuous cCR for more than 1 year). The secondary endpoints include rates of Grade 3-4 acute adverse effects (AEs) etc. Results: Up to 30 September 2022, 62 patients attending our center were enrolled (Consolidation arm: 34, Induction arm:28). Their median age was 53 (27-69) years. Fifty-nine of them had MSS/pMMR type cancer (95.2%), and only three MSI-H/dMMR. Additionally, 55 patients (88.7%) had Stage III disease. The following important characteristics were distributed as follows: lower location (≤5 cm from anus, 48/62, 77.4%), deeper invasion by primary lesion (cT4 7/62, 11.3%; mesorectal fascia involved 17/62, 27.4%), and high risk of distant metastasis (cN2 26/62, 41.9%; EMVI+ 11/62, 17.7%). All 62 patients completed the SCRT and at least five cycles of ToriCAPOX, 52/62 (83.9%) completing six cycles of ToriCAPOX. Finally, 29 patients achieved cCR (46.8%, 29/62), 18 of whom decided to adopt a W&W strategy. TME was performed on 32 patients. Pathological examination showed 18 had achieved pCR, four TRG 1, and 10 TRG 2-3. The three patients with MSI-H disease all achieved cCR. One of these patients was found to have pCR after surgery whereas the other two adopted a W&W strategy. Thus, the pCR and CR rates were 56.2% (18/32) and 58.1% (36/62), respectively. The TRG 0-1 rate was 68.8% (22/32). The most common non-hematologic AEs were poor appetite (49/60, 81.7%), numbness (49/60, 81.7%), nausea (47/60, 78.3%) and asthenia (43/60, 71.7%); two patients did not complete this survey. The most common hematologic AEs were thrombocytopenia (48/62, 77.4%), anemia (47/62, 75.8%), leukopenia/neutropenia (44/62, 71.0%) and high transaminase (39/62, 62.9%). The main Grade III-IV AE was thrombocytopenia (22/62, 35.5%), with three patients (3/62, 4.8%) having Grade IV thrombocytopenia. No Grade V AEs were noted. Conclusions: SCRT-based total neoadjuvant therapy combined with toripalimab can achieve a surprisingly good CR rate in patients with LARC and thus has the potential to offer new treatment options for organ preservation in patients with MSS and lower-location rectal cancer. Meanwhile, the preliminary findings of a single center show good tolerability, the main Grade III-IV AE being thrombocytopenia. The significant efficacy and long-term prognostic benefit need to be determined by further follow-up.

In recent years, the clinical treatment of colorectal cancer(CRC) has made great progress, but chemoresistance is still one of the main reasons for reducing the survival rate of patients with colorectal cancer. Therefore, ameliorating chemotherapy resis-tance is an urgent problem to be solved. The purpose of this study was to investigate the regulatory role and related molecular mechanisms of hydroxysafflor yellow A(HSYA) in colorectal cancer cell proliferation, migration, and 5-fluorouracil(5-FU) chemoresistance. In this study, HCT116 and HT-29 cells were used as research subjects. Firstly, methyl thiazolyl tetrazolium(MTT) assay and colony formation assay were used to detect and analyze the effect of HSYA on the proliferation of CRC cells. Secondly, the effect of HSYA on the cell cycle in CRC cells was analyzed by cell cycle assay. Furthermore, the effect of HSYA on the migration of CRC cells was analyzed by wound-healing assay and Transwell assay. Based on the above, the influences of HSYA on 5-FU chemoresistance of CRC cells and related molecular mechanisms were explored and analyzed. The results showed that HSYA significantly inhibited the proliferation and migration of CRC cells, and arrested the cell cycle in G_0/G_1 phase. In addition, HSYA significantly ameliorated the chemoresistance of CRC cells to 5-FU. The results of acridine orange staining and Western blot showed that the autophagy activity of CRC cells in the HSYA and 5-FU combined treatment group was significantly higher than that in the 5-FU single drug treatment group. As compared with the 5-FU single drug treatment group, the phosphorylation levels of protein kinase B(Akt) and mammalian target of rapamycin(mTOR) in the HSYA and 5-FU combined treatment group were significantly reduced, indicating that the Akt/mTOR signaling pathway in the combined treatment group was down-regulated in CRC cells. In conclusion, HSYA may upregulate autophagy activity through the Akt/mTOR signaling pathway, thereby inhibiting the proliferation and migration of CRC cells and ameliorating the chemoresistance to 5-FU.

Objective:To construct a combined diet and exercise program for puerperal women with Yin-deficiency constitution based on traditional Chinese medicine (TCM) constitution identification, and evaluate the effect of this program.Methods:This study was guided by the complex intervention development framework of the UK Research Council, and based on the TCM constitution identification, and determined the combined diet and exercise program for puerperal women with Yin-deficiency constitution based on TCM constitution identification through literature review, case analysis, group discussion, and Delphi method. From October to December 2022, convenience sampling was used to select 76 delivery women with Yin-deficiency constitution who delivered at Shenzhen Hospital of Southern Medical University as the research subject. According to the delivery time, the delivery women were divided into a control group ( n=37) and an experimental group ( n=39). The control group adopted routine postpartum nursing. On this basis, the experimental group implemented the combined diet and exercise program for puerperal women with Yin-deficiency constitution based on TCM constitution identification. We compared the Yin-deficiency constitution score, duration of lochia, and incidence of puerperium complications between two groups of delivery women before and after intervention. Results:The final constructed program included 6 primary indicators, 20 secondary indicators, and 50 tertiary indicators. In the two rounds of consultation, the positivity coefficients of experts were all 100%, the authority coefficients of experts were 0.827 and 0.843, and the Kendall harmony coefficients were 0.419 and 0.502, respectively with a statistical difference ( P<0.01). After intervention, the score of Yin-deficiency constitution, duration of lochia, and incidence of puerperium complications in the experimental group were lower than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The combined diet and exercise program for puerperal women with Yin-deficiency constitution based on TCM constitution identification is scientific, comprehensive, and feasible, which can provide reference for future development of TCM constitution management during the puerperium.

Objective:To study the utility of immunohistochemistry (IHC) in differential diagnosis between trichoblastoma (TB) and basal cell carcinoma (BCC).Methods:Fifty-eight cases of TB and 40 cases of BCC were collected at Fudan University Shanghai Cancer Center from January 2009 to December 2019 and retrospectively analyzed by IHC for bcl-2, Ber-EP4, CD10, CK20 and Ki-67. Fisher exact test was performed for statistical analysis.Results:Twenty-five (43.1%) TBs and 5 (12.5%) BCCs showed bcl-2 staining in the outermost layer of the epithelial nests, the difference was statistically significant ( P<0.01). The proportion of cases with bcl-2 staining>75% of epithelial cells in BCC group was much higher than that in TB group (40% vs. 12.1%; P<0.01). BCC group showed larger proportions with Ber-EP4 staining>75%, 51%-75% of epithelial cells than TB group (12.5% vs. 1.7%, 37.5% vs. 8.6%; P<0.05). Fifty-five (94.8%) TBs demonstrated CD10 expression in the follicular stroma, while only 16 (40.0%) BCCs showed focal or scattered CD10 expression in reactive fibrous stroma ( P<0.01). CK20 expression was present in 37 (63.8%) TBs with scattered pattern, but BCCs exhibited no CK20 staining except for only one case (2.5%) showing focal staining ( P<0.01). Compared with TB group, the BCC group included more cases with Ki-67 labeling index ≥15% on average and ≥25% in hotspot areas ( P<0.05). Conclusion:IHC is helpful in differential diagnosis between TB and BCC. Scattered CK20 staining pattern and stromal CD10 expression support the diagnosis of TB. Bcl-2 staining limited to the outermost layer of the proliferation is more likely to be found in TB. In contrast, Ber-EP4 positivity and higher Ki-67 labeling index tend to be present in BCC.

Objective:To investigate the clinicopathological characteristics, differential diagnosis and prognosis of nodal nevi (NN).Methods:Eighteen cases of NN diagnosed at Fudan University Shanghai Cancer Center, Shanghai, China from 2009 to 2019 were collected. The clinicopathological characteristics and follow-up data were retrospectively analyzed. Histopathologic evaluation and immunohistochemical studies were carried out. The Vysis Melanoma FISH Probe Kit, combined with 9p21(CDKN2A) and 8q24(MYC) assays were performed in 2 cases.Results:There were 2 males and 16 females in the case series. The age of the patients ranged from 36 to 70 years (average 48.2 years). Fifteen cases located in axillary lymph nodes, 1 in inguinal lymph node, 1 in cervical lymph node, and 1 in external iliac lymph node. NN was found in only one lymph node in each case. Histologically, the nevus cell aggregates were found in capsule of lymph nodes in all cases. Nevus cells grew along the capsule into trabeculae in 8 cases, with 3 of them scattered in parenchyma. In one of these 8 cases, nevus cell aggregates massively occupied the parenchyma of the lymph node. The largest lesions in the 18 NN cases measured from 0.2 to 6.5 mm. All of the NN cases were classified as conventional nevi. The majority of the cases were composed of uniform nevus-like cells and identical to cutaneous pigmented nevi without atypia, necrosis, or mitosis. In the NN case that massively occupied parenchyma, some areas had abundant nevus cells and displayed atypical cytologic features, including increased nucleo-cytoplasmic ratio, small nucleoli, and occasional mitotic figures. Immunohistochemistry was performed in 13 cases. All of them were positive for S-100, SOX10, Melan A, and p16. HMB45 showed weak staining in rare cells of only one case out of 13 cases. Ki-67 labeling index <1% was found in all 13 cases. Additionally, the results of FISH assay were both negative. All patients were followed up for 13 to 129 months (median 31.5 months). Except that one patient died of the salivary gland carcinoma, the other patients all survived without tumor during the follow-up period.Conclusions:NN is a benign melanocytic lesion in lymph node. It is important to distinguish NN from metastatic melanoma when nevus cells occur in parenchyma and subcapsular sinus of lymph nodes, or show some atypical cytologic features. The morphology of bland nevus cells in capsule and trabeculae is a valuable clue. Besides, immunohistochemical profiling and FISH assay are helpful in the differential diagnosis.
