Objective To explore the technical process and clinical application of laparoscopic combined upper midline incision minimally invasive liver transplantation. Methods A retrospective analysis was conducted on 30 cases of laparoscopic combined upper midline incision minimally invasive liver transplantation. The cases were divided into cirrhosis group (15 cases) and liver failure group (15 cases) based on the primary disease. The surgical and postoperative conditions of the two groups were compared. Results All patients successfully underwent laparoscopic "clockwise" liver resection, with no cases of passive conversion to open surgery or intolerance to pneumoperitoneum. In 6 cases, the right lobe was relatively large, and the right hepatic ligaments could not be completely mobilized. One case required an additional reverse "L" incision during open surgery. All patients successfully completed the liver transplantation, with no major intraoperative bleeding, cardiovascular events, or other occurrences in the 30 patients. The model for end-stage liver disease (MELD) score in the cirrhosis group was lower than that in the liver failure group (P<0.001). There were no statistically significant differences between the two groups in terms of age, surgical time, blood loss, anhepatic phase, or cold ischemia time (all P>0.05). During the perioperative period, there was 1 case of hepatic artery embolism, 1 case of portal vein anastomotic stenosis, no complications of hepatic vein and inferior vena cava, and 3 cases of biliary anastomotic stenosis, all of which occurred in the liver failure group. Conclusions In strictly selected cases, the minimally invasive liver transplantation technique combining laparoscopic hepatectomy with upper midline incision for graft implantation has the advantages of smaller incisions, less bleeding, relatively easier operation, and faster postoperative recovery, which is worthy of clinical promotion and application.

Objective:To systematically analyze the overview of "Internet + nursing service" in holistic nursing, explore the hotspots and evolution trends in both Chinese and English, so as to provide reference and ideas for further promoting the efficient development of "Internet + nursing service".Methods:The literature was sourced from China National Knowledge Infrastructure, WanFang Data, Web of Science (WOS) Core Database, and Embase, with a search period from January 2015 to June 2023. CiteSpace software was used for statistical analysis of literature volume, countries, institutions, authors, keywords and so on, and to draw visual graphs.Results:A total of 2 124 Chinese literature and 2 775 English literature were included. The research force of "Internet + nursing service" was mainly developed countries, and China was in a rapid development stage. Chinese research hotspots and trends included the construction and application of Internet information platform, construction of service model, establishment of evaluation index system, and participation willingness and cognition survey of relevant people. English research hotspots and trends involved Internet based home care service and mobile health care service.Conclusions:The research of "Internet + nursing service" in China is in a rapid development stage, and the collaboration between scholars and institutions is insufficient. It is urgent to establish a multi-center and multidisciplinary cross cooperation. Chinese research focuses on the construction of the basic operation system. The trend of English research suggests that nursing researchers can give full play to the advantages of the Internet, carry out multi-dimensional innovative research from the service model, service population and laws and regulations, and provide scientific methods for the in-depth development of "Internet + nursing service".

Objective:To analyze the immune reconstitution after BTKi treatment in patients with chronic lymphocytic leukemia(CLL).Methods:The clinical and laboratorial data of 59 CLL patients admitted from January 2017 to March 2022 in Fujian Medical University Union Hospital were collected and analyzed retrospectively.Results:The median age of 59 CLL patients was 60.5(36-78).After one year of BTKi treatment,the CLL clones(CD5+/CD19+)of 51 cases(86.4％)were significantly reduced,in which the number of cloned-B cells decreased significantly from(46±6.1)× 109/L to(2.3±0.4)× 109/L(P=0.0013).But there was no significant change in the number of non-cloned B cells(CD19+minus CD5+/CD19+).After BTKi treatment,IgA increased significantly from(0.75±0.09)g/L to(1.31±0.1)g/L(P＜0.001),while IgG and IgM decreased from(8.1±0.2)g/L and(0.52±0.6)g/L to(7.1±0.1)g/L and(0.47±0.1)g/L,respectively(P＜0.001,P=0.002).BTKi treatment resulted in a significant change in T cell subpopulation of CLL patients,which manifested as both a decrease in total number of T cells from(2.1±0.1)× 109/L to(1.6±0.4)× 109/L and NK/T cells from(0.11±0.1)× 109/L to(0.07±0.01)× 109/L(P=0.042,P=0.038),both an increase in number of CD4+cells from(0.15±6.1)× 109/L to(0.19±0.4)× 109/L and CD8+cells from(0.27±0.01)× 109/L to(0.41±0.08)× 109/L(both P＜0.001).BTKi treatment also up-regulated the expression of interleukin(IL)-2 while down-regulated IL-4 and interferon(IFN)-γ.However,the expression of IL-6,IL-10,and tumor necrosis factor(TNF)-α did not change significantly.BTKi treatment could also restored the diversity of TCR and BCR in CLL patients,especially obviously in those patients with complete remission(CR)than those with partial remission(PR).Before and after BTKi treatment,Shannon index of TCR in patients with CR was 0.02±0.008 and 0.14±0.001(P＜0.001),while in patients with PR was 0.01±0.03 and 0.05±0.02(P＞0.05),respectively.Shannon index of BCR in patients with CR was 0.19±0.003 and 0.33±0.15(P＜0.001),while in patients with PR was 0.15±0.009 and 0.23±0.18(P＜0.05),respectively.Conclusions:BTKi treatment can shrink the clone size in CLL patients,promote the expression of IgA,increase the number of functional T cells,and regulate the secretion of cytokines such as IL-2,IL-4,and IFN-γ.BTKi also promote the recovery of diversity of TCR and BCR.BTKi treatment contributes to the reconstitution of immune function in CLL patients.

Objective:To explore the changes of large-scale functional brain networks and network topological properties in patients with major depressive disorder (MDD) whose diagnosis had not changed after 5 years of follow-up.Methods:Totally 521 cases of hospitalized MDD patients were recruited from January 2012 to August 2018, and another 204 cases of gender- and age-matched healthy controls were recruited. All participants completed resting-state functional magnetic resonance scanning and clinical assessment. Their diagnosis were reviewed 5 years after discharge.A total of 258 participants whose diagnosis had not changed were counted into the MDD group for analysis. The differences in large-scale brain network connectivity between the two groups were analyzed by constructing a whole-brain functional network, on the basis of which the altered topological properties of the sensorimotor network (SMN), visual network (VN) and default mode network (DMN) were further analyzed between the two groups.The SPSS 24.0 software was used for data analysis and the independent sample t-test and χ2 test were used for the data comparison of the two groups. Results:Compared with the healthy controls, the MDD group had significantly decreased network clustering, mainly involving the SMN, VN and DMN (edge P<0.001, cluster P<0.05). The MDD group had decreased functional connectivity(FC) strength within the SMN, VN and DMN networks, the FC strength between the SMN and VN networks, between the frontoparietal network (FPN) and the DAN networks were decreased(all P<0.05, FDR corrected). Graph-theory analysis showed that local efficiency, clustering coefficient, and normalized shortest path length were decreased in the MDD group, node efficiency was decreased in the left ventral medial prefrontal cortex and the middle of the bilateral insula, node centrality was decreased in the middle of the bilateral insula and occipital lobe, and the betweenness was decreased in the middle of the right insula (all P<0.05, FDR corrected). Conclusion:MDD exhibits abnormal network functional connectivity, disruption of network topological properties, diminished optimal information processing, and to some extent reflects the severity of depressive symptoms. The decreased ability of information transfer flow in the insula plays an important role for the functional abnormality of the network.

Objective To construct a management program for upper limb lymphedema prevention in postopera-tive breast cancer patients and to evaluate its effectiveness.Methods The first draft of the upper limb lymphede-ma prevention and management protocol for postoperative breast cancer patients was constructed on the basis of ev-idence summaries and qualitative interviews,and 2 rounds of correspondence were conducted in December 2022.Using the convenience sampling method,patients undergoing surgery for malignant tumours in the breast surgery de-partment of a tertiary-level hospital in Zhengzhou City were selected as the study subjects,and 58 patients admitted from January to March 2023 were included in the experimental group according to the time of their first visit.57 patients admitted from July to December 2022 were included in the control group and were given routine care.The rates of lymphedema occurrence,upper limb function score and patients'adherence to lymphedema prevention be-haviours after 1,3,and 6 months of intervention were compared between the 2 groups.Results The valid ques-tionnaire recovery rates of the 2 rounds of expert correspondence were 92.59％and 100％,and the authority coeffi-cients of the experts were 0.940 and 0.950,and the Kendall's harmony coefficients were 0.228 and 0.254,respec-tively(P＜0.00 1).The coefficients of variation of the 2nd round of correspondence were 0.07～0.24.The final draft of the programme included 5 first-level entries,12 second-level entries,and 32 third-level entries.During the appli-cation of the programme,a total of 5 cases were dislodged,and 55 cases were finally included in each of the ex-perimental and control groups.The results of repeated measures ANOVA showed that there was an interaction ef-feet between the upper limb function scores and lymphedema prevention behavior compliance scores before inter-vention and at 1,3,and 6 months after discharge between the 2 groups(P＜0.05).Simple effects analysis showed that at 1,3,and 6 months after discharge,the upper limb function score and lymphedema prevention behavior com-pliance score of the experimental group were better than those of the control group,and the differences were sta-tistically significant(P＜0.05).At 6 months post-intervention,the difference in the occurrence of lymphedema was statistically significant when comparing the 2 groups(P=0.032).Adverse events such as subcutaneous bruising and falls did not occur in either group.Conclusion The upper limb lymphoedema prevention and management pro-gramme for postoperative breast cancer patients constructed in this study is scientific,feasible and safe,and can ef-fectively reduce the incidence of lymphoedema in patients and improve their quality of life.

Partial nephrectomy (PN) is primarily used to treat small size renal cell carcinoma (RCC), aiming to minimize the impact on kidney function. Although the recurrence rate post-PN is low, vigilance in diagnosing recurrence is crucial to differentiate it from inflammatory pseudotumor (IPT) and therefore prevent unnecessary interventions. In the case of a 56-year-old female patient who underwent PN for RCC of the right kidney, a mass was identified in the original surgical site over a year later, raising concerns of local recurrence based on imaging findings. However, when the patient declined puncture biopsy, a Radical Nephrectomy (RN) was performed instead. Subsequent pathology results revealed the presence of IPT, not tumor recurrence. This case underscores the importance of a comprehensive analysis of imaging features to accurately diagnose postoperative recurrence following PN. Where uncertainty persists, puncture biopsy should be considered to provide a definitive diagnosis. Moreover, emphasizing ongoing training in PN techniques and adherence to established protocols is essential to minimize the likelihood of complications such as trauma and infection, thereby reducing the occurrence of both postoperative PN recurrence and IPT.

Objective:To investigate the incidence and prothrombotic risk factors of postoperative venous thromboembolism(VTE) in Cushing′s disease and to further develop an assessment model to identify those at high risk of postoperative VTE events.Methods:A retrospective study was performed in 82 patients who were admitted to Huashan Hospital, Fudan University during January 2019 and January 2020 and diagnosed with Cushing′s disease. These patients underwent the evaluation about their clinical, hormonal, and coagulation parameters, as well as ultrasonography and pulmonary angio-CT when necessary. The least absolute shrinkage and selection operator(LASSO) regression analysis was used to screen independent risk factors, and a nomogram model for postsurgical VTE risk assessment in Cushing′s disease was initially established, and Bootstrap method was used for internal verification. Finally, the predictive model was evaluated for calibration and clinical applicability in the study cohort.Results:Nineteen patients(23.17%) developed VTE events, with 14 cases occurring after endoscopic transsphenoidal surgery. Compared to patients without VTE, those in the VTE group were older( P<0.001), had longer postoperative bed rest, higher rates of current infection, higher HbA 1C levels, and more severe glucose tolerance impairment(all P<0.05). Through LASSO regression analysis, two independent risk factors for postoperative VTE were identified: Age and current infection. Then a VTE risk assessment nomogram model was established to predict the patients at high risk of VTE. In the nomogram model for VTE risk assessment, the area under the receiver operating characteristic curve was 0.868(95% CI 0.787-0.949), with the calibration curve closely aligning with the ideal diagonal line and the clinical decision curve exceeding the two extreme curves. Conclusions:Advanced perioperative assessment needs to be taken to screen those with high VTE risks in patients diagnosed with Cushing′s disease. Additionally, during the perioperative period, patients with Cushing′s disease should undergo mandatory physical activity or prophylactic anticoagulant therapy.

Objective:To reveal the effect of β-sitosterol on cerebral ischemia-reperfusion injury (CIRI) in rats and whether its mechanism is related to endoplasmic reticulum stress (ERS).Methods:Fifty-three CIRI rats (CIRI models established by modified Longa method) were randomly divided into model group ( n=14), β-sitosterol low-dose group ( n=13), β-sitosterol medium-dose group ( n=13) and β-sitosterol high-dose group ( n=13); 12 rats underwent the same operation without blocking the middle cerebral artery were selected as sham-operated group. Rats in the sham-operated group and model group were given intragastric administration of 1 mL 5 g/L sodium carboxymethyl cellulose daily. Rats in the β-sitosterol low-dose group, β-sitosterol medium-dose group and β-sitosterol high-dose group were given intragastric administration of 1 mL β-sitosterol at 10, 20 and 40 mg/kg/d (dissolved in 5 g/L sodium carboxymethyl cellulose), respectively, for 14 consecutive d. Neurological function was evaluated according to Zea Longa 5 method. Rats were sacrificed and brain tissues were collected. Volume of cerebral infarction was measured by 2,3,5-triphenyl tetrazolium chloride (TTC) staining. Brain injury and neuronal apoptosis were evaluated by HE staining, Nissl staining and TUNEL. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) contents were detected by water-soluble tetrazolium 1 (WST-1) method, colorimetric method or thiobarbituric acid (TBA) method, respectively. The mRNA and protein expression levels of protein kinase R-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme-1 (IRE-1), activated transcription factor-6 (ATF-6), glucose-regulated protein 78 (GRP78), C/EBP homologous protein (CHOP) and Caspase-12 in the brain tissues were detected by qRT-PCR or Western blotting. Results:Compared with the sham-operated group, the model group had significantly increased neurological function score, cerebral infarction volume and TUNEL positive rate, decreased SOD and GSH-Px content, increased MDA content, and increased mRNA and protein expressions of PERK, IRE-1, ATF-6, GRP78, CHOP and Caspase-12 ( P<0.05). Compared with the model group, the β-sitosterol low-dose group, β-sitosterol medium-dose group and β-sitosterol high-dose group had significantly decreased neurological function score, cerebral infarction volume, and TUNEL positive rate, increased SOD and GSH-Px content, and decreased MDA content ( P<0.05); the β-sitosterol low-dose group, β-sitosterol medium-dose group and β-sitosterol high-dose group had significantly decreased mRNA and protein PERK expressions (mRNA: 2.17±0.17, 1.79±0.07 and 1.33±0.07; protein: 5.11±0.52, 2.91±0.26 and 1.98±0.17), IRE-1 expressions (mRNA: 1.75±0.18, 1.65±0.08 and 1.32±0.08; protein: 5.00±0.31, 4.05±0.27 and 1.98±0.14), ATF-6 expressions (mRNA: 2.24±0.12, 1.77±0.14 and 1.37±0.13; protein: 4.93±0.45, 4.04±0.30 and 3.10±0.20), GRP78 expressions (mRNA: 2.67±0.16, 2.11±0.16 and 1.69±0.11; protein: 5.02±0.38, 2.97±0.26 and 2.05±0.22), CHOP expressions (mRNA: 2.01±0.16, 1.70±0.19 and 1.40±0.10; protein: 4.92±0.39, 4.02±0.27 and 3.08±0.22) and Caspase-12 expressions (mRNA: 1.85±0.09, 1.61±0.09 and 1.30±0.09; protein: 3.03±0.20, 2.19±0.11 and 1.82±0.11) compared with the model group (mRNA: 2.99±0.28, 2.27±0.12, 2.57±0.21, 3.46±0.20, 2.50±0.23 and 2.35±0.16; protein: 6.98±0.48, 6.03±0.58, 5.98±0.63, 7.10±0.45, 6.00±0.53 and 5.02±0.43, P<0.05). Conclusion:β-sitosterol attenuates CIRI in rats, whose mechanism may be related to inhibition of ERS signal pathway.

Objective To explore the clinical efficacy of repeated transcranial magnetic stimulation(rTMS)and acupuncture therapy in the treatment of chronic insomnia disorder(CID)patients.Methods A total of 80 patients with CID,who were treated at Nanchang First Hospital from January 2022 to December 2023,were selected for the study.The patients were randomly divided into control group and treatment group,with 40 cases in each group.The control group patients were treated with dexmedetomidine,while the treatment group patients received rTMS and acupuncture therapy in addition to control group.The treatment course was 4 weeks,and the sleep quality,sleep related indicators,and psychological condition improvement of both groups of patients were observed before and after treatment.Results After treatment,the Pittsburgh sleep quality index scores of both groups of patients decreased(P＜0.05);The sleep latency and number of awakenings were lower than before treatment(P＜0.05),and the total sleep time,sleep efficiency,and proportion of rapid eye movement sleep were higher than before treatment,treatment group showed more significant improvement than control group(P＜0.05).After treatment,the Hamilton anxiety and depression scale scores of both groups of patients decreased compared to before treatment,but there was no statistically significant difference in control group before and after treatment(P＞0.05).However,there was a statistically significant difference in treatment group before and after treatment(P＜0.05).Conclusion The combination of rTMS and acupuncture treatment can significantly improve the sleep quality of CID patients,while also reducing the accompanying symptoms of anxiety and depression.

Objective:To investigate the specimen quality of intersphincteric resection with transabdominal transanal mixed approach for rectal cancer in the Chinese Transanal Total Mesorectal Excision Registry Collaborative (CTRC) database.Methods:The retrospective case-control study was conducted. Based on the concept of real-world research, the clinicopathological data of 281 pati-ents with rectal cancer in the CTRC database who underwent intersphincteric resection with trans-abdominal transanal mixed approach in 19 medical centers, including the Beijing Friendship Hospital of Capital Medical University et al, from November 15,2017 to December 31,2023 were collected.

Observation indicators: (1) preoperative examinations; (2) neoadjuvant therapy; (3) postoperative examinations; (4) analysis of influencing factors for positive circumferential margin in surgical specimen of intersphincteric resec-tion for rectal cancer. Measurement data with normal distribution were represented as Mean±SD. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers or percentages. The chi-square test was used for univariate analysis. Logistic regression model was used for multivariate analysis. Results:(1) Preoperative examinations. Of the 281 patients, 234 cases underwent preoperative pelvic magnetic resonance imaging (MRI) examina-tion. There were 2 cases in clinical stage T0, 3 cases in clinical stage T1, 58 cases in clinical stage T2, 137 cases in clinical stage T3, 24 cases in clinical stage T4, 3 cases in clinical stage Tx, 7 cases missing clinical T staging data. There were 87 cases in clinical stage N0, 68 cases in clinical stage N1, 60 cases in clinical stage N2, 9 cases in clinical stage Nx, 10 cases missing clinical N staging data. There were 30 cases with mesorectal fascia invasion, 53 cases with extramural venous invasion. The distance from lower margin of tumor to anal margin was 41.9(range, 1.0-80.0)mm. (2) Neoadjuvant therapy. Of the 281 patients, 125 cases underwent neoadjuvant therapy, including 39 cases receiving chemo-therapy alone, 6 cases receiving short-course simultaneous chemoradiotherapy, 5 cases receiving short-course simultaneous chemoradiotherapy and delayed surgery, 48 cases receiving long-course simultaneous chemoradiotherapy, 2 cases receiving other treatments, and 25 cases missing neoadju-vant therapy data. (3) Postoperative examinations. Of the 281 patients, 249 cases achieved R 0 resection, 9 cases achieved R 1 resection, and there were 23 cases missing surgical margin data. The maximum tumor diameter, the number of lymph nodes harvested and positive rate of vessel carcinoma embolus were 30.0(range, 0.5-200.0)mm, 13(range, 0-70) and 27.55%(73/265) in 281 patients. There were 252 patients with circumferential margin records, showing positive in 15 cases, with a positive rate as 5.95%(15/252). The minimum distance from deep part of tumor to circumferential margin was 7.0(range, 0-150.0)mm in 252 patients. There were 85 cases with distal margin records, showing positive in 1 case, and the distance from lower margin of tumor to distal margin was 10.0(range, 0-202.0)mm. There were 273 patients with specimen integrity records, which showed intact specimen in 208 cases, fair specimen in 58 cases, poor specimen in 4 cases, unevaluated specimen in 3 cases. There were 7 cases with rectal perforation. Of the 281 patients, cases in pathological stage T0, Tis, T1, T2, T3, T4 were 14, 5, 22, 107, 113, 12, respectively, and there were 8 cases missing pathological T staging data. Of the 281 patients, cases in pathological stage N0, N1a, N1b, N1c, N2a, N2b were 176, 27, 27, 11,20, 12, respectively, and there were 8 cases missing pathological N staging data. Of the 281 patients, there were 4 cases with distant metastasis, 262 cases without distant metastasis, 5 cases not evaluated, and 10 cases missing tumor metastasis data. Of the 125 patients undergoing neoadjuvant therapy, there were 85 cases with tumor regression grade records, including 16 cases as grade 1, 27 cases as grade 2, 19 cases as grade 3, 15 cases as grade 4, 8 cases as grade 5. (4) Analysis of influencing factors for positive circumferential margin in surgical specimen of intersphincteric resection for rectal cancer. Results of univariate analysis showed that preoperative T staging on preoperative pelvic MRI, mesorectal fascia invasion, extramural venous invasion, pathological T staging, and pathological N staging were related factors for positive circumferential margin in surgical specimen of intersphincteric resection for rectal cancer ( P<0.05). Conclusions:Intersph-incteric resection with transabdominal transanal mixed approach has good specimen quality and low positive rate of surgical margin. T staging on preoperative pelvic MRI may be related to positive circumferential margin after intersphincteric resection for rectal cancer.
