Objective:To investigate the effect and safety of pancreatic extracorporeal shock wave lithotripsy (P-ESWL) in treating the chronic pancreatitis (CP) patients with main pancreatic duct (MPD) stones and to analyze the influencing factors of success of lithotripsy.Methods:Clinical data of 132 patients with CP complicated with MPD stones treated with P-ESWL in the Department of Gastroenterology, Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2022 to December 2023 were retrospectively analyzed, including 103 males and 29 females, aged (50.3±16.9) years. The times of P-ESWL, the success rate of stone fragmentation, the necessity of combining endoscopic retrograde cholangiopancreatograhy (ERCP), clearance rate of MPD stones, and incidence of post-P-ESWL complications (acute pancreatitis, abdominal hematoma, infection, steinstrasse, perforation, etc.) were evaluated. The factors influencing the success rate of lithotripsy were analyzed using univariate and multivariate logistic regression.Results:All patients underwent P-ESWL treatment, with (2.23±0.82) times of P-ESWL per person. The success rate of stone fragmentation was 87.1%(115/132). Of 107 CP patients (81.1%, 107/132) were treated with their first P-ESWL. Of 12 patients (9.1%, 12/132) underwent single P-ESWL, and 120 (90.9%, 120/132) underwent P-ESWL combined with ERCP. There were 95 cases (72.0%, 95/132) with effective removal of stones, and 62 (47.0%, 62/132) with complete removal of stones. Post-P-ESWL complications included eight cases (6.1%, 8/132) of acute pancreatitis, two (7.6%, 2/132) of steinstrasse complicated with acute pancreatitis and one (0.8%, 1/132) of abdominal hematoma. No infection or perforation occurred. Multivariate logistic regression analysis showed that the higher CT value of stones ( OR=1.239, 95% CI: 1.040-1.477, P=0.017) was associated with the lower success rate of stone fragmentation. Conclusion:P-ESWL is safe and effective in treating patients with CP complicated with MPD stones. The CT value of stones is a risk factor for the success rate of P-ESWL.

This study aims to investigate the effect of Chaijin Jieyu Anshen Formula on the neuroinflammation of rats with insomnia complicated with depression through the regulation of triggering receptor expressed on myeloid cells 2(TREM2)/complement protein C1q signaling pathway. Rats were randomly divided into a normal group, a model group, a positive drug group, as well as a high, medium, and low-dose groups of Chaijin Jieyu Anshen Formula, with 10 rats in each group. Except for the normal group, the other groups were injected with p-chlorophenylalanine and exposed to chronic unpredictable mild stress to establish the rat model of insomnia complicated with depression. The sucrose preference experiment, open field experiment, and water maze test were performed to evaluate the depression in rats. Enzyme-linked immunosorbent assay was employed to detect serum 5-hydroxytryptamine(5-HT), dopamine(DA), and norepinephrine(NE) levels. Hematoxylin and eosin staining and Nissl staining were used to observe the damage in nucleus accumbens neurons. Western blot and immunofluorescence were performed to detect TREM2, C1q, postsynaptic density 95(PSD-95), and synaptophysin 1(SYN1) expressions in rat nucleus accumbens, respectively. Golgi-Cox staining was utilized to observe the synaptic spine density of nucleus accumbens neurons. The results show that, compared with the model group, Chaijin Jieyu Anshen Formula can significantly increase the sucrose preference as well as the distance and number of voluntary activities, shorten the immobility time in forced swimming test and the successful incubation period of positioning navigation, and prolong the stay time of space exploration in the target quadrant test. The serum 5-HT, DA, and NE contents in the model group are significantly lower than those in the normal group, with the above contents significantly increased after the intervention of Chaijin Jieyu Anshen Formula. In addition, Chaijin Jieyu Anshen Formula can alleviate pathological damages such as swelling and loose arrangement of tissue cells in the nucleus accumbens, while increasing the Nissl body numbers. Chaijin Jieyu Anshen Formula can improve synaptic damage in the nucleus accumbens and increase the synaptic spine density. Compared to the normal group, the expression of C1q protein was significantly higher in the model group, while the expression of TREM2 protein was significantly lower. Compared to the model group, the intervention with Chaijin Jieyu Anshen Formula significantly downregulated the expression of C1q protein and significantly upregulated the expression of TREM2. Compared with the model group, the PSD-95 and SYN1 fluorescence intensity is significantly increased in the groups receiving different doses of Chaijin Jieyu Anshen Formula. In summary, Chaijin Jieyu Anshen Formula can reduce the C1q protein expression, relieve the TREM2 inhibition, and promote the synapse-related proteins PSD-95 and SNY1 expression. Chaijin Jieyu Anshen Formula improves synaptic injury of the nucleus accumbens neurons, thereby treating insomnia complicated with depression.

Actinomycosis is a rare chronic granulomatous disease characterized by granuloma formation and tissue fibrosis with sinus tracts,often misdiagnosed due to its similarity to many infectious and non-infectious diseases.This report presents a case of a 60-year-old female with more than 10 years history of rheumatoid arthritis who developed actinomycosis infection after long-term treatment with immunosuppressants and biologics,including methotrexate,leflunomide,and infliximab,leading to recurrent joint pain,poorly controlled rheumatoid arthritis activity,and persistent elevation of white blood cell counts.Abdominal CT revealed a pelvic mass and right ureteral dilation.Pathological examination of cervical tissue showed significant neutrophil infiltration and sulfur granules,indicating actinomycosis.The patient received 18 months of doxycycline treatment for the infection and continued rheumatoid arthritis therapy with leflunomide,hydroxychloroquine sulfate,and tofacitinib,resulting in improved joint symptoms and normalized white blood cell counts.After 2 years of follow-up,the patient remained stable with no recurrence.This case highlights the importance of clinicians being vigilant for infections,particularly chronic,occult infections from rare pathogens,in rheumatoid arthritis patients on potent immunosuppressants and biologics,advocating for early screening and diagnosis.

Phosphodiesterase-4 (PDE4) functions as a catalyzing enzyme targeting hydrolyzation of intracellular cyclic adenosine monophosphate (cAMP) and inhibition of PDE4 has been proven to be a competitive strategy for dermatological and pulmonary inflammation. However, the pathological role of PDE4 and the therapeutic feasibility of PDE4 inhibitors in chronic ulcerative colitis (UC) are less clearly understood. This study introduced apremilast, a breakthrough in discovery of PDE4 inhibitors, to explore the therapeutic capacity in dextran sulfate sodium (DSS)-induced experimental murine chronic UC. In the inflamed tissues, overexpression of PDE4 isoforms and defective cAMP-mediating pathway were firstly identified in chronic UC patients. Therapeutically, inhibition of PDE4 by apremilast modulated cAMP-predominant protein kinase A (PKA)-cAMP-response element binding protein (CREB) signaling and ameliorated the clinical symptoms of chronic UC, as evidenced by improvements on mucosal ulcerations, tissue fibrosis, and inflammatory infiltrations. Consequently, apremilast maintained a normal intestinal physical and chemical barrier function and rebuilt the mucosal homeostasis by interfering with the cross-talk between human epithelial cells and immune cells. Furthermore, we found that apremilast could remap the landscape of gut microbiota and exert regulatory effects on antimicrobial responses and the function of mucus in the gut microenvironment. Taken together, the present study revealed that intervene of PDE4 provided an infusive therapeutic strategy for patients with chronic and relapsing UC.

Objective:To investigate the clinical efficacy of pancreaticoduodenectomy with TRIANGLE operation in the treatment of pancreatic head cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 51 patients with pancreatic head cancer who were admitted to the Sichuan Provincial People′s Hospital, Affiliated Hospital of School of Medicine of University of Electronic Science and Technology of China from January 2017 to July 2018 were collected. There were 33 males and 18 females, aged from 42 to 74 years, with a median age of 56 years. Of the 51 patients, 24 cases undergoing standard pancreaticoduodenectomy, in which No.12, 13 and 17 lymph nodes were dissected, combined with transcatheter arterial infusion chemo-therapy (TAI) were allocated into the standard group, and 27 cases undergoing pancreaticoduo-denectomy with TRIANGLE operation, in which No.7, 8, 9, 12, 13, 16, 17 lymph nodes were dissected, combined with TAI were allocated into the TRIANGLE group, respectively. Observation indicators: (1) intraoperative conditions of the two groups; (2) postoperative conditions of the two groups; (3) follow-up and survival. Follow-up was conducted using outpatient examination and telephone interview once three months to detect tumor recurrence and metastasis and survival of patients up to July 2021 or the death of patient. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the chi-square test or the Fisher exact probability. Comparison of ordinal data was analyzed using the rank sum test. Kaplan‐Meier method was used to calculate the survival rate and median survival time and draw survival curve. Log‐Rank test was used for survival analysis. Results:(1) Comparison of intraoperative conditions between the two groups. The operation time, volume of intraoperative blood loss, cases with intraoperative blood transfusion were (501±61)minutes, (563±278)mL, 4 in the standard group, versus (556±46)minutes, (489±234)mL, 6 in the TRIANGLE group, respectively. There was a significant difference in the operation time between the two groups ( t=3.62, P<0.05) but there was no significant difference in the volume of intraoperative blood loss or cases with intraoperative blood transfusion between the two groups ( t=1.03, χ2=0.25, P>0.05).

There was no significant difference in cases with postoperative complications, cases with delayed gastric emptying, cases with pancreatic fistula between the two groups ( χ2=0.16, 0.02, Z=-0.04, P>0.05) and there was no significant difference in cases with biliary fistula, cases with bleeding, cases with diarrhea between the two groups ( P>0.05). Cases with complications as Clavien-Dindo grade Ⅰ, grade Ⅱ, grade Ⅲ were 10, 11, 2 in the standard group, versus 8, 18, 1 in the TRIANGLE group, showing no significant difference between the two groups ( Z=-0.67, P>0.05). The duration of postoperative hospital stay was (23±8)days in both of the standard group and the TRIANGLE group, showing no significant difference between the two groups ( t=0.31, P>0.05). (3) Follow-up and survival. All the 51 patients were followed-up for 6 to 54 months, with a median follow-up time of 17 months. The postoperative 1-year overall survival rate was 75.0% and 81.5% in the standard group and the TRIANGLE group, respectively. The postoperative 3-year overall survival rate was 12.5% and 22.2% in the standard group and the TRIANGLE group, respectively. The median postoperative survival time was 15.00 months (95% confidence interval as 12.63 to 17.37 months) and 21.00 months (95% confidence interval as 15.91 to 19.62 months) in the standard group and the TRIANGLE group, respectively. There was a significant difference in survival of patients between the two groups ( χ2=4.30, P<0.05). Cases with tumor recurrence during post-operative 1 year and 3 year were 9 and 20 in the standard group, versus 6 and 15 in the TRIANGLE group, respectively. There was no significant difference in cases with tumor recurrence during postoperative 1 year between the two groups ( P>0.05) and there was a significant difference in cases with tumor recurrence during postoperative 3 year between the two groups ( P<0.05). Conclusion:Compared with standard pancreaticoduodenectomy, pancreaticoduodenectomy with TRIANGLE operation can prolong the median survival time of patients with pancreatic head cancer without increasing surgical related complications.

OBJECTIVE: To study the long-term clinical effect of multicenter multidisciplinary treatment (MDT) in children with renal malignant tumors. METHODS: A retrospective analysis was performed on the medical data of 55 children with renal malignant tumors who were diagnosed and treated with MDT in 3 hospitals in Hunan Province from January 2015 to January 2020, with GD-WT-2010 and CCCG-WT-2016 for treatment regimens. A Kaplan-Meier survival analysis was used to analyze the survival of the children. RESULTS: Of the 55 children, 10 had stage I tumor, 14 had stage Ⅱ tumor, 22 had stage Ⅲ tumor, 7 had stage IV tumor, and 2 had stage V tumor. As for pathological type, 47 had FH type and 8 had UFH type. All children underwent complete tumor resection. Of the 55 children, 14 (25%) received preoperative chemotherapy. All children, except 1 child with renal cell carcinoma, received postoperative chemotherapy. Among the 31 children with indication for radiotherapy, 21 (68%) received postoperative radiotherapy. One child died of postoperative metastasis. The incidence rate of FH-type myelosuppression was 94.4%, and the incidence rate of UFH-type myelosuppression was 100%. The median follow-up time was 21 months and the median survival time was 26 months for all children, with an overall survival rate of 98% and an event-free survival rate of 95%. CONCLUSIONS Multicenter MDT has the advantages of high success rate of operation and good therapeutic effect of chemotherapy in the treatment of children with renal malignant tumors, with myelosuppression as the most common side effects, and radiotherapy is safe and effective with few adverse events. Therefore, MDT has good feasibility, safety, and economy.

Objective:To investigate the expression of serum matrix metalloproteinase 3 (MMP-3) in patients with rheumatoid arthritis (RA) and analyze its correlation with bone erosion and disease activity.Methods:100 RA patients diagnosed in the First People's Hospital of Changde from July 2018 to December 2019 were selected as the RA group, and 35 healthy volunteers who came to the hospital for physical examination at the same time were selected as the control group. The clinical data of the patients were collected, and the serum MMP-3 levels of the patients and healthy volunteers were detected by enzyme-linked immunosorbent assay (ELISA). The serum MMP3 levels of RA patients with different disease activity, different imaging stages and different bone mineral density were compared, and the correlation with clinical indicators were analyzed.Results:⑴ RA patients were grouped according to the Disease Activity Score (DAS) 28. Serum MMP-3 levels in the highly active group (300.87±15.93)ng/ml and in the moderately active group (213.78±12.79)ng/ml were higher than those in the clinical remission group (82.87±8.19)ng/ml increased significantly. ⑵ The serum MMP3 level in the RA group (190.98±13.43)ng/ml was significantly higher than that in the healthy control group (69.97±10.63)ng/ml. ⑶ There were significant differences in serum MMP-3 levels among RA patients with different imaging stages ( P<0.05). The level of MMP-3 in stage Ⅲ (206.18±13.58)ng/ml and stage Ⅳ (301.72±13.43)ng/ml were significantly higher than those in stage Ⅰ (89.16±10.13)ng/ml. ⑷ RA patients were divided into normal group, osteopenia group, and osteoporosis group according to bone mineral density. The serum MMP-3 level in the osteopenia group (180.87±12.69)ng/ml and osteoporosis group (289.54±13.28)ng/ml were significantly higher than that in the normal group (121.05±8.45)ng/ml. ⑸ Serum MMP-3 levels were positively correlated with C-reaction (CRP), erythrocyte sedimentation rate (ESR), DSA 28, rheumatoid factor (RF), joint swelling index, joint tenderness index, and platelet count in the RA group ( P<0.05). Conclusions:The serum MMP-3 plays an important role in the progression of RA, and is closely related to RA disease activity and bone erosion. It is expected to become a serological indicator for predicting RA bone erosion and radiological progress.

Of 49 patients undergoing endoscopic treatment, 4 patients with stent related complications were cured after replacing stent under endoscopy, 6 patients had acute pancreatitis, 2 had gastrointestinal bleeding including 1 patient was cured after endoscopic hemostasis, other patients with complications were improved after symptomatic and supportive treatment. Of 79 patients undergoing surgical treatment, 17 had pancreatic leakage (including 11 of biochemical leakage, 5 of grade B pancreatic leakage, and 1 of grade C pancreatic leakage), 3 had postoperative gastroparesis, 3 had intraabdominal infection, 1 had deep venous thrombosis, 2 had hemorrhage of which 1 combined with grade C pancreatic leakage was improved after open hemostasis and 1 was improved after interventional treatment, other patients with complications were improved after symptomatic and supportive treatment. Conclusions:For chronic pancreatitis, individualized treatment should be formulated according to the different stages. M-ANNHEIM score system can be used the evaluate clinical efficacies of drug treatment, endoscopic treatment, and surgical treatment.
