BACKGROUND:Traditional surgery for lumbar disc herniation involves extensive excision of tissue surrounding the nerve for decompression and removal of protruding lumbar intervertebral discs,which poses various risks and complications such as nerve damage causing paralysis,lumbar instability,herniation recurrence,intervertebral space infection,and adjacent vertebral diseases. OBJECTIVE:To propose the symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous technique for lumbar spine symmetrically decompression,showing the induced resorption of herniated nucleus pulpous phenomenon and early clinical efficacy,and then analyze its decompression mechanism. METHODS:214 patients with lumbar disc herniation at Department of Orthopedics,First Affiliated Hospital of Zhengzhou University from March 2021 to May 2023 were enrolled in this study.Among them,81 patients received conservative treatment as the control group,and 133 patients received symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous treatment as the trial group.Before surgery,immediately after surgery(7-14 days),and early after surgery(over 1 year),MRI images were used to measure the volume changes of lumbar disc herniation.CT images were used to measure the posterior displacement distance of the lumbar spinous process ligament complex,as well as the width and height of the lateral recess.Japanese Orthopaedic Association scores were used to evaluate the patient's neurological function recovery. RESULTS AND CONCLUSION:(1)Control group:81 patients with lumbar disc herniation were treated conservatively,with a total of 171 herniated lumbar discs.The average follow-up time was(22.7±23.1)months.The first and second MRI measurements of 171 herniated lumbar discs showed herniated lumbar disc volumes of(551.6±257.9)mm3 and(792.2±330.4)mm3,respectively,with an average volume increase rate of(53.2±44.4)%,showing statistically significant differences(P<0.001).Out of 171 herniated lumbar discs,4 experienced natural shrinkage,with an absorption ratio of 2.3%(4/171)and an absorption rate of(24.5±9.9)%.(2)Trial group:133 patients with lumbar disc herniation had a total of 285 herniated lumbar discs.(1)Immediately after surgery:All patients were followed up immediately after surgery.229 out of 285 herniated lumbar discs experienced retraction,with an absorption ratio of 80.3%(229/285)and an average absorption rate of(21.5±20.9)%,with significant and complete absorption accounting for 6.5%.There were a total of 70 herniated lumbar discs in the upper lumbar spine,with an absorption ratio of 85.7%(60/70),an average absorption rate of(23.1±19.5)%,and a maximum absorption rate of 86.6%.There were 215 herniated lumbar discs in the lower lumbar spine,with an absorption ratio of 78.6%(169/215),an average absorption rate of(21.0±21.3)%,and a maximum absorption rate of 83.2%.Significant and complete absorption of the upper and lower lumbar vertebrae accounted for 5.7%and 6.5%,respectively,with no statistically significant difference(P>0.05).The average distance of posterior displacement of the spinous process ligament complex immediately after surgery was(5.2±2.8)mm.There were no significant differences in the width and height of the left and right lateral recess before and immediately after surgery(P>0.05).The Japanese Orthopaedic Association score immediately after surgery increased from(10.1±3.4)before surgery to(17.0±4.8),and the immediate effective rate after surgery reached 95.6%.(2)Early postoperative period:Among them,46 patients completed the early postoperative follow-up.There were 101 herniated lumbar discs,with an absorption ratio of 94%(95/101)and an average absorption rate of(36.9±23.7)%.Significant and complete absorption accounted for 30.6%,with a maximum absorption rate of 100%.Out of 101 herniated lumbar discs,3 remained unchanged in volume,with a volume invariance rate of 2.97%(3/101).Out of 101 herniated lumbar discs,3 had an increased volume of herniated lumbar discs,with an increase ratio of 2.97%(3/101)and an increase rate of(18.5±18.4)%.The Japanese Orthopaedic Association score increased from preoperative(9.3±5.1)to(23.5±4.0),with an excellent and good rate of 93.4%.(3)The early postoperative lumbar disc herniation absorption ratios of the control group and trial group were 2.3%and 85.9%,respectively,with statistically significant differences(P<0.001).(4)Complications:There were two cases of incision exudation and delayed healing in the trial group.After conservative treatment such as dressing change,no nerve injury or death occurred in the incision healing,and no cases underwent a second surgery.(5)It is concluded that symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous is a new method for treating lumbar disc herniation that can avoid extensive excision of the"ring"nerve and achieve satisfactory early clinical efficacy.It does not damage the lumbar facet joints or alter the basic anatomical structure of the lateral recess,fully preserves the herniated lumbar discs,and can induce significant or even complete induced resorption of herniated nucleus pulpous.Symmetrically adduction of lumbar decompression induced resorption of herniated nucleus pulpous provides a new basis and method for the clinical treatment of lumbar disc herniation.

Objective:To observe the clinical efficacy and safety of Jianpi Bushen Jiedu Prescription combined with 5-fluorouracil (5-FU)-based chemotherapy and targeted therapy for the treatment of advanced colorectal cancer patients with liver and kidney yin deficiency combined with spleen deficiency pattern.Methods:A randomized controlled trial was conducted. A total of 72 hospitalized patients with advanced colorectal cancer treated at the Department of Oncology, Nanjing Hospital of Traditional Chinese Medicine Affiliated to Nanjing University of Chinese Medicine from October 2022 to January 2024 were enrolled as study subjects. Using a random number table method, they were allocated into two groups, with 36 patients in each group. The control group received the mFOLFOX6/FOLFIRI combined with bevacizumab regimen, while the treatment group was administered additional oral Jianpi Bushen Jiedu Prescription on the basis of the control group. Two weeks was a cycle in both groups, with a total of 6 cycles of treatment. Serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 199 (CA199), and carbohydrate antigen 724 (CA724) were detected using electrochemiluminescence; the Karnofsky Performance Status (KPS) scale was utilized to evaluate patients' functional status; vital signs were continuously monitored, and adverse reactions were recorded. The short-term efficacy and TCM syndrome efficacy of patients were evaluated.Results:The treatment group demonstrated higher objective response rate (ORR) [31.25% (10/32) vs. 21.88% (7/32), χ2=0.72] and disease control rate (DCR) [84.38% (27/32) vs. 71.88% (23/32), χ2=1.46] compared to the control group, without statistical significance ( P>0.05). Post-treatment levels of CEA [4.09 (3.31,8.57) μg/L vs. 10.07 (4.55,22.35) μg/L, Z=-2.10] and CA72-4 [4.54 (2.04,10.99) mU/L vs. 9.48 (4.34,18.95) mU/L, Z=-2.52] in the treatment group were significantly lower than those in the control group ( P<0.05). The total effective rate of TCM syndrome was significantly higher in the treatment group [78.13% (25/32)] compared with the control group [50.00% (16/32)], with statistical significance ( χ2=5.50, P=0.019). Post-treatment KPS scores in the treatment group [80.0 (80.0, 80.0) vs. 70.0 (62.5, 80.0), Z=-2.76] were significantly higher compared with the control group ( P<0.01). During the treatment period, the treatment group showed statistical significance compared with the control group in the incidence of hemoglobin decrease ( χ2=4.66), leukopenia decrease ( χ2=4.27), and peripheral neuropathy ( χ2=3.93), with statistical significance ( P<0.05). Conclusion:The addition of Jianpi Bushen Jiedu Prescription to 5-FU-based chemotherapy combined with targeted therapy demonstrates significant clinical benefits in advanced colorectal cancer patients, including reducing tumor marker levels, alleviating clinical symptoms, improving quality of life, and mitigating treatment-related toxicities, with a good safety.

Objective:To improve the diagnosis and treatment of autoimmune hepatitis (AIH) in children by analyzing their clinical characteristics and outcomes.Methods:Case summary.The general data, clinical manifestations, laboratory parameters, liver pathology, treatment and outcomes of 6 AIH children diagnosed at Xi′an Children′s Hospital from January 2019 to March 2024 were retrospectively analyzed.Results:All the 6 patients were diagnosed with AIH-1, and 5 of them were female, accounting for 83.3%.The median age of onset was 6.2 years old.Three cases (50.0%) had insidious onset.Elevated hepatic aminotransferase levels were detected incidentally in 2 cases (33.3%).One case (16.7%) presented symptoms resembling those of viral hepatitis.Two cases (33.3%) were accompanied by extrahepatic autoimmune diseases.All the children tested positive for anti-nuclear antibodies with a titer ≥1∶80 or 1∶100.Four cases (66.7%), 3 cases (50.0%), and 1 case (16.7%) tested positive for anti-smooth muscle antibodies, anti-perinuclear neutrophil cytoplasm antibodies and anti-soluble liver antigen, respectively.Liver pathology showed infiltration of lymphocytes-plasma cells and moderate or severe interfacial inflammation in all the 6 cases.Two cases (33.3%) had rosettes.All the patients were given oral corticosteroids combined with Azathioprine or Mycophenolate mofetil.The patients were followed up for 24.8 (12.0-52.0) months, during which 3 cases (50.0%) had partial remission and 3 cases (50.0%) achieved complete remission.Four cases (66.7%) showed transaminase fluctuations during corticosteroid reduction or cessation.Conclusions:Autoantibodies and liver pathology are important evidence for diagnosing AIH in children.Immunosuppressants have a high remission rate in the treatment of this disease, but transaminase fluctuations are prone to occur during corticosteroid reduction or cessation.

Objective:To evaluate the feasibility of " two-stitch" fashion in laparoscopic pancreaticojejunostomy (PJ) for patients with fine pancreatic duct (<3 mm).Methods:Clinical data of 32 patients with pancreatic duct diameter <3 mm undergoing laparoscopic PJ using the " two-stitch" fashion between Apr 2021 and Jun 2024 were retrospectively analyzed, including 20 males and 12 females, aged (61.2±23.7) years. Among the patients, there were 23 (71.9%) patients of periampullary tumor and 9 (28.1%) of central pancreatic tumor. 23 (71.9%) patients underwent laparoscopic pancreatoduodenectomy (LPD) and nine (28.1%) underwent laparoscopic central pancreatectomy (LCP). All patients underwent the " two-stitch" fashion of laparoscopic PJ (one stitch each on the ventral and dorsal sides of pancreas for duct-to-mucosal anastomosis). The operation time, PJ time, postoperative hospital stay, postoperative complications (pancreatic fistula, gallbladder leakage, abdominal cavity infection, etc) and mortality were recorded.Result:All patients underwent the " two stitch" laparoscopic PJ successfully, 23(71.9%) patients underwent laparoscopic pancreatoduodenectomy (LPD) and nine (28.1%) underwent laparoscopic central pancreatectomy (LCP). The operation time was (279.3±115.8) min, the PJ time was (31.9±12.2) min, and the postoperative hospital stay was (13.4±8.3) d. Grade B pancreatic fistula occurred in six cases (18.8%, four of LPD and two of LCP), delayed gastric emptying in one case of LPD (3.1%), abdominal infection in three cases (9.4%, two of LPD and one of LCP), biliary fistula in two cases (6.3%, LPD). There were no grade C pancreatic fistula. All patients with postoperative complications were managed with conservative treatment.Conclusion:Laparoscopic " two stitch" PJ for patients with fine pancreatic duct (<3 mm) is safe and feasible.

Objective:To evaluate the efficacy and safety of laparoscopic hepatectomy (LH) versus open hepatectomy (OH) for malignant liver tumors in unfavorable regions using propensity score matching (PSM) analysis.Methods:Clinical data of 181 patients with malignant liver tumors in unfavorable regions undergoing hepatic resection at the Department of Hepatopancreatobiliary Surgery, Affiliated Jinhua Hospital, Zhejiang University School of Medicine, between January 2013 and February 2019, including 130 males and 51 females, aged (56.4±12.5) years. Patients were divided into two groups according to surgical approach: the OH group ( n=128) and LH group ( n=53). Clinical parameters including age, gender, hepatitis B history, operative time, and postoperative complications were recorded. PSM (1∶1 nearest neighbor matching with a caliper width of 0.04) was performed using surgical approach as the dependent variable and covariates as independent variables. Survival analysis was conducted via the Kaplan-Meier method, with intergroup survival rates were compared using log-rank tests. Results:Prior to PSM, significant intergroup differences were observed in age, hepatitis B status, cirrhosis, and microvascular invasion (all P<0.05). After PSM, 74 patients (37 per group) achieved balance in baseline characteristics (all P>0.05). Post-PSM analysis revealed significantly shorter postoperative hospitalization in LH group compared to that in OH group [9(7, 10) d vs. 11(10, 13) d, P<0.05]. No perioperative mortality occurred in either group. The OH group exhibited a higher postoperative complication rate than the LH group did [37.8% (14/37) vs. 16.2% (6/37), χ2=4.39, P=0.036]. No significant differences were observed in cumulative recurrence-free survival ( χ2=0.44, P=0.508) or overall survival ( χ2<0.01, P=0.997) between groups. Conclusion:For malignant liver tumors in unfavorable regions, LH compared favourable open surgery, regarding the reduced invasiveness, shorter hospitalization, and lower complication rates, while maintaining comparable oncological outcomes. LH represents a safe and feasible surgical approach in selected cases.

Corneal alkali burns are a common form of corneal trauma, and their treatment has been a challenge in ophthalmology. Traditional treatments include anti-inflammatory, immunosuppressive, and corneal transplantation, with limited results. This review focuses on the research progress of mesenchymal stem cells(MSCs)and their derived extracellular vesicles(MSCs-EVs)in the treatment of corneal alkali burns. MSCs have the ability of self-renewal, multidirectional differentiation, and immunomodulation, and the MSCs-EVs inherit its function from MSCs. MSCs-EVs inherit the functions of MSCs and has lower immunogenicity and better biocompatibility, which provides a new avenue for ophthalmic treatment. In addition, bioscaffolds are used as scaffolds or drug delivery systems in tissue engineering to promote tissue regeneration due to their excellent biocompatibility and degradability. This article reviews the mechanism of action and research progress of MSCs-EVs and combined bioscaffolds in the treatment of corneal alkali burns, and explores their potential in promoting the repair of corneal alkali burns and improving vision. These findings provide new strategies for the treatment of corneal alkali burns and are expected to improve the prognosis of patients.

Growth arrest DNA damage-inducible protein 45 β (GADD45B) has been reported to be a regulatory factor for active DNA demethylation and is implicated in the modulation of synaptic plasticity and chronic stress-related psychopathological processes. However, its precise role and mechanism of action in stress susceptibility remain elusive. In this study, we found a significant reduction in GADD45B expression specifically in the ventral, but not the dorsal hippocampal CA1 (dCA1) of stress-susceptible mice. Furthermore, we demonstrated that GADD45B negatively regulates susceptibility to social stress and NMDA receptor-dependent long-term potentiation (LTP) in the ventral hippocampal CA1 (vCA1). Importantly, through pharmacological inhibition using the NMDA receptor antagonist MK801, we provided further evidence supporting the hypothesis that GADD45B potentially modulates susceptibility to social stress by influencing NMDA receptor-mediated LTP. Collectively, these results suggested that modulation of NMDA receptor-mediated synaptic plasticity is a pivotal mechanism underlying the regulation of susceptibility to social stress by GADD45B.
