ABSTRACT

【Objective】 To explore the emergency treatment of penoscrotal avulsion injury based on the American Association for Surgery and Trauma (AAST) penoscrotal injury grade. 【Methods】 Data of 30 patients with penoscrotal avulsion injury treated in our hospital with in-situ suture, skin grafting or skin flap during Oct.2003 and Dec.2017 were reviewed. 【Results】 Among the 30 patients, 29 received emergency surgery, including in-situ suturein 15 grade Ⅰ-Ⅲ cases, skin graft in 8 grade Ⅳ-Ⅴ cases, and skin flap in 6 cases;1 case received delayed operation due to wound infection on admission. In the perioperative period,25 cases had more than 90% wound healing, 3 cases had 70% wound healing after wound dressing change, and 2 cases had complete necrosis. Second-stage skin graft yielded satisfactory penoscrotal appearance. 【Conclusion】 According to the specific conditions of patients, reasonable surgical methods can be selected. For grade Ⅰ-Ⅲ patients, in-situ suture can be used, while for grade Ⅳ-Ⅴ patients, wound condition, age, fertility and other factors should be taken into consideration so as to preserve the function of testis to the maximum extent.

ABSTRACT

Background/Aims@#To investigate the autoantibody against fumarate hydratase (FH), which is a specific liver failure-associated antigen (LFAA) and determine whether it can be used as a biomarker to evaluate the prognosis of acute-on-chronic liver failure (ACLF). @*Methods@#An immunoproteomic approach was applied to screen specific LFAAs related to differential prognosis of ACLF (n=60). Enzyme-linked immunosorbent assay (ELISA) technology was employed for the validation of the frequency and titer of autoantibodies against FH in ACLF patients with different prognoses (n=82). Moreover, we clarified the expression of autoantibodies against FH in patients with chronic hepatitis B (n=60) and hepatitis B virus-related liver cirrhosis (n=60). The dynamic changes in the titers of autoantibodies against FH were analyzed by sample collection at multiple time points during the clinical course of eight ACLF patients with different prognoses. @*Results@#Ultimately, 15 LFAAs were screened and identified by the immunoproteomic approach.Based on ELISA-based verification, anti-FH/Fumarate hydratase protein autoantibody was chosen to verify its expression in ACLF patients. ACLF patients had a much higher anti-FH autoantibody frequency (76.8%) than patients with liver cirrhosis (10%, p=0.000), patients with chronic hepatitis B (6.7%, p=0.022), and normal humans (0%, p=0.000). More importantly, the frequency and titer of anti-FH protein autoantibodies in the serum of ACLF patients with a good prognosis were much higher than that of patients with a poor prognosis (83.9% vs 61.5%, p=0.019; 1.41±0.85 vs 0.94±0.56, p=0.017, respectively). The titer of anti-FH autoantibodies showed dynamic changes in the clinical course of ACLF. @*Conclusions@#The anti-FH autoantibody in serum may be a potential biomarker for predicting the prognosis of ACLF.

ABSTRACT

ObjectiveTo investigate the effects of epidural analgesia plus dexmedetomidine infusion on postpartum depression in parturients with natural childbirth. MethodsWe selected 70 parturients aged between 22 and 36, with singleton, term, cephalic presentation, natural delivery and ASA class I or Ⅱ. The cases undergoing epidural analgesia with ropivacaine and sufentanil were randomly divided into two groups by using a random number table (n=35 for each group). The control group (Group C) used intravenous infusion of normal saline, while the experimental group (Group D) used equivalent volumes of intravenous infusion of dexmedetomidine. Participants were followed up at 1, 6, 12 weeks after childbirth to assess the severity of postpartum depression. Blood samples were collected at 12 h and 48 h after childbirth to measure the serum prolactin levels. The hemodynamic (HR and MAP) changes, VAS scores, and Ramsay scores were recorded at five time points: before analgesia (T1), 10 min after analgesia (T2), 30 min after analgesia (T3), 12 h (T4) and 24 h (T5) after delivery. The number of analgesia pump presses and adverse events were also documented. ResultsCompared with Group C, Group D showed significantly lower EPDS scores at 1 week after childbirth, significantly higher prolactin concentrations at 12 h and 48 h after childbirth, significantly lower VAS scores at T2, T3 and T4, significantly higher Ramsay score at T3 and significantly reduced number of analgesia pump presses (P < 0.05). ConclusionEpidural analgesia plus intravenous infusion of dexmedetomidine can alleviate early postpartum depression in women undergoing natural delivery, promote early prolactin secretion and provide a safe and effective adjunctive analgesic and sedative effect.

ABSTRACT

ObjectiveTo investigate the characteristics of traditional Chinese medicine syndrome and the evolution of pathogenesis in different stages of atherosclerotic thrombotic cerebral infarction (ATCI). MethodsClinical data of 3088 ATCI patients from 8 hospitals in 6 provinces and cities were collected from the hospital information system during January 1, 2015 to December 31, 2019. After staging and counting clinical symptoms, common factors were extracted using the principal component analysis method in factor analysis. Cluster analysis was then carried out on the basis of the factor analysis. The results of the combination of the evidence element identification, cluster analysis and expert discussion were used to discuss the evidence of the different disease stages of atherosclerotic cerebral infarction. ResultsOf the 3088 ATCI patients included, 2290 cases were in the acute phase and 798 in the non-acute phase. Excluding the main symptoms of ischaemic stroke, such as numbness and weakness of limbs, unfavourable movement, unfavourable speech and dizziness, we identified 84 indicators with a frequency ≥5% of the four diagnostic information variables. Of these, 36 indicators were observed in the acute phase and 35 in the non-acute phase. Factor analysis extracted 14 common factors from each phase. We selected factors with a loading coefficient >0.3 for evidence determination. These 14 groups of common factors were used as variables for clustering. After clustering, the acute, non-acute phase were each divided into 5 categories. Based on a combination of clinical practice and expert opinion, the symptoms identified in the acute period were syndrome of deficiency of both qi and yin, syndrome of blockade of wind-phlegm-static blood (36.07%), syndrome of qi deficiency and blood stasis (20.74%), syndrome of upward disturbance of wind-fire (15.15%), syndrome of stirring wind due to yin deficiency (9.43%), and syndrome of spleen deficiency and liver hyperactivity (3.80%). In the non-acute phase, the symptoms were qi and yin deficiency with syndrome of qi stagnation and blood stasis (45.49%), syndrome of deficiency of both qi and yin (20.05%), syndrome of qi stagnation and blood stasis (16.42%), spleen-kidney deficiency syndrome (8.52%), and syndrome of hyperactivity of liver yang (4.89%). ConclusionThe acute phase of AICI is mainly characterized by blood stasis, fire, internal wind, hyperactivity of yang, qi deficiency and yin deficiency, while the non-acute phase is characterized by yin deficiency, qi deficiency, blood stasis and qi stagnation. The main pathomechanism of ATCI involves deficiency of qi and yin, as well as obstruction of the channels by phlegm and blood stasis, and the fundamental pathomechanism is deficiency of qi and yin.

ABSTRACT

Objective:To explore the distribution features of resident CD8 + T cells infiltration in human esophageal cancer tissues and its clinical significance. Methods:Data from the Cancer Genome Atlas database were retrieved, the correlation between CD103 + CD8 + T cells and infiltration degree of conventional type 1 dendritic cell (cDC1), conventional type 2 dendritic cell (cDC2), type 3 dendritic cell(DC3) was investigated. From January 2006 to December 2008, 78 esophageal cancer tissues and 75 adjacent normal tissues from 78 esophageal cancer patients were collected by Shanghai Outdo Biotechnology Co., Ltd, the clinical data of patients was followed up by telephone until July 2015. The distribution of CD8 + T cells and CD103 + CD8 + T cells in cancer tissues and adjacent normal tissues was detected by multi-color labeling techniques and multispectral tissue imaging. The differences of the number and the ratio of CD8 + T cells and CD103 + CD8 + T cells in cancer tissues and adjacent normal tissues were compared. The Kaplan-Meier survival curves of patients with tissue infiltration of CD8 + T cells and CD103 + CD8 + T cells at different levels were drawn through the R language " survminer" package, and the best cut-off value was obtained. TNM stage, pathological stage and other clinical parameters of patients with high and low infiltration of CD8 + T cells, CD103 + CD8 + T cells were compared. Wilcoxon rank sum test, chi-square test, log-rank test and Cox proportional risk regression model statistical analysis were used to evaluate the prognostic value of the above indicators. Spearman correlation analysis was used for correlation analysis. Results:In the cancer tissues of patients with esophageal cancer, the infiltration degree of CD103 + CD8 + T cells was positively correlated with the infiltration degree of cDC1 cells, cDC2 cells and DC3 cells ( r=0.67, 0.53 and 0.47, all P<0.001). The percentage of CD8 + T cells in all cells in the whole tissue core of tumor tissues (63.09% (42.14%, 76.21%)) was higher than that of adjacent normal tissues (2.56% (1.68%, 5.38%)), and the difference was statistically significant ( U=41.00, P<0.001). The proportion of CD103 + CD8 + T cells in all cells in the whole tissue core of tumor tissues (7.92% (1.60%, 20.61%)) was higher than that of adjacent normal tissues (0.04% (0.01%, 0.10%)), and the difference was statistically significant ( U=857.50, P<0.001). The percentage of high CD8 + T cells infiltration in esophageal cancer tissues of patients with pathological stage Ⅰ+ Ⅱ was lower than that of patients with stage Ⅲ+ Ⅳ (57.9%, 33/57 vs. 85.7%, 18/21); the percentage of high CD103 + CD8 + T cells in CD8 + T cells in esophageal cancer tissues of patients with TNM stage Ⅰ+ Ⅱ was lower than that of patients with stage Ⅲ+ Ⅳ (21.6%, 8/37 vs. 48.8%, 20/41), and the differences were both statistically significant ( χ2=5.25 and 6.23, P=0.022 and 0.013). The results of Kaplan-Meier survival analysis and univariate Cox proportional risk regression model showed that the overall survival (OS) of patients with high CD8 + T cell infiltration was longer than that of patients with low CD8 + T cell infiltration ( HR=0.57, 95% confidence interval (95% CI) 0.34 to 0.96, P=0.034). There was no significant difference in OS between patients with high CD103 + CD8 + T cell infiltration and patients with low CD103 + CD8 + T cell infiltration ( HR=0.66, 95% CI 0.40 to 1.08, P>0.05). Conclusion:The high infiltration of CD103 + CD8 + T cells in esophageal cancer tissues are expected to be used as a prognostic predictor for patients with esophageal cancer, which is an important component of anti-tumor immune response in tumor microenvironment of esophageal cancer.

ABSTRACT

Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) is a new imaging technique with label-free, rapid, and high throughput features. It has bloomed in the analysis on the spatial distribution of biomolecules such as drugs, metabolites, peptides and proteins on the tissue surface in virtue of providing high data throughput from non-targeted full analysis and high accuracy from targeted analysis. The acquisition of MSI signal response with high sensitivity, high spatial resolution, and good stability is directly depended on the appropriate sample preparation approaches, and flexible and various data processing tools will help the non-target data mining to meet the demands of visualization, spatial distribution and multiple index applications so as to reveal the scientific rules beneath the data. This review briefly summarizes the key advances in MALDI-MSI from aspects of sample preparation procedures, data processing and visualization. It also illustrates the characteristics, difficulties and probable solutions derived from these key techniques.

ABSTRACT

Development of extramural health care for chronic wounds is still in its infancy in China, and thus it is urgent and vital to establish a correct concept and practicable principles. The authors reviewed recent domestic and international literature and summarized the following treatment procedures and principles for extramural health care of chronic wounds. (1) The patient needs to do self-assessment of the wound by using available simple methods; (2) The patient consults with professional physicians or nurses on wound care to define the severity and etiology of the non-healing wound; (3) Professionals evaluate the existing treatment strategies; (4) Etiological treatments are given by professionals; (5) Patients buy needed dressings via the more convenient ways from pharmacies, e-commerce platform or others; (6) Professionals provide a standardized and reasonable therapeutic plan based on the patient's wound conditions; (7) Both professionals and the patient pay attention to complications to prevent adverse outcomes; (8) Professionals strengthen the public education on wound care and integrated rehabilitation. This review expected to provide new perspectives on the therapeutic strategies for chronic wounds in an extramural setting.

ABSTRACT

In recent years, the incidence of renal cancer has been increasing continuously. Surgical resection is the "gold standard" for the treatment of small renal cancer. However, local ablation therapy of renal cancer is undoubtedly the best choice for patients with short life expectancy, other complications, and impaired renal function who are not suitable for surgery. In recent years, with the development of ablation techniques and long-term follow-up, local ablation has shown good therapeutic effects. As many domestic hospitals are performing or planning to perform renal tumor cryoablation to improve the clinical cure rate and surgical safety of renal tumor cryoablation, it is necessary to standardize the surgical indications, contraindications, perioperative management, efficacy evaluation, and other common problems. Currently, there is no expert consensus regarding perioperative renal tumor cryoablation in China. To standardize the perioperative management of renal tumor cryoablation and related technical operations in clinical practice, and improve the effectiveness and safety of cryoablation, the expert committee of Tumor Interventional and Minimally Invasive Diagnosis and Treatment Continuing Education Base of the Chinese Anti-Cancer Association convened experts in related fields to discuss and formulate this consensus, which is hereby published, for clinical reference and application.

ABSTRACT

Objective: To elucidate the clinical features of patients with refractory juvenile dermatomyositis (JDM), and to explore the efficacy and safety of tofacitinib in the treatment of refractory JDM. Methods: A total of 75 JDM patients admitted to the Department of Rheumatology and Immunology in Shenzhen Children's Hospital from January 2012 to January 2021 were retrospectively analyzed, and to analyze the clinical manifestations, efficacy and safety of tofacitinib in the treatment of refractory JDM. Patients were divided into refractory group with using of glucocorticoids in combination with two or more anti-rheumatic drugs for treatment, and the presence of disease activity or steroid dependence after a one-year follow-up. The non-refractory group is defined as clinical symptoms disappeared, laboratory indicators were normal, and clinical remission was achieved after initial treatment, and the clinical manifestations and laboratory indexes of the two groups were compared. The Mann-Whitney U test, Fisher's precision probability test was used for intergroup comparison. Binary Logistic multivariate regression analysis was used to identify risk factors for refractory JDM. Results: Among the 75 children with JDM, 41 were males and 34 were females with a age of onset of 5.3 (2.3, 7.8) years. The refractory group consisted of 27 cases with a age of onset of 4.4 (1.5, 6.8) years, while the non-refractory group consisted of 48 cases with a age of onset of 5.9 (2.5, 8.0) years. Compared with 48 cases in the non-refractory group, the proportion of interstitial lesions and calcinosis in the refractory group was higher than that in the non-refractory group (6 cases (22%) vs. 2 cases (4%), 8 cases (30%) vs. 4 cases (8%), both P<0.05). Binary Logistic regression analysis showed that observation group were more likely to be associated with to interstitial lung disease (OR=6.57, 95%CI 1.22-35.31, P=0.028) and calcinosis (OR=4.63, 95%CI 1.24-17.25, P=0.022). Among the 27 patients in the refractory group, 22 cases were treated with tofacitinib, after treatment with tofacitinib, 15 of 19 cases (86%) children with rashes showed improvement, and 6 cases (27%) with myositis evaluation table score less than 48 score both were improved, 3 of 6 cases (27%) had calcinosis were relieved, and 2 cases (9%) had glucocorticoid-dependence children were successfully weaned off. During the tofacitinib treatment, there was no increase in recurrent infection, blood lipids, liver enzymes, and creatinine were all normal in the 22 cases. Conclusions: Children with JDM with calcinosis and interstitial lung disease are more likely to develop refractory JDM. Tofacitinib is safe and effective for refractory JDM.

ABSTRACT

Our studies were aimed to explore the effect and mechanism of the inhibition of the formation of vasculogenic mimicry (VM) in human glioblastoma cells by Xihuang pill (XHP) medicated serum through regulating the hypoxia inducible factor-1α (HIF-1α)/vascular endothelial growth factor A (VEGFA)/vascular endothelial growth factor receptor 2 (VEGFR2) signaling pathway. The medicated serum of XHP was prepared by gavage for 7 days to male SD rats (approval number of animal experiment ethics: 202105A051). The hypoxia model of U251 cells was established using 200 μmol·L-1 of CoCl2. After treatment with XHP-medicated serum, cell viability and proliferation of U251 cells were detected by CCK-8 and cell cloning experiment. Cell apoptosis and cell cycle of U251 cells were determined by flow cytometry. Cell migration and invasion were evaluated by wound healing and Transwell invasion assay. The formation of VM was assessed by three-dimensional cell culture of U251 cells. The protein expression levels of HIF-1α, VEGFA, VEGFR2, phosphorylated-VEGFR2 (p-VEGFR2), vascular endothelial-cadherin (VE-cadherin), Eph receptor tyrosine kinases A2 (EphA2), matrix metalloproteinase 2 (MMP2), matrix metalloproteinase 14 (MMP14) and laminin γ2 in U251 cells were detected by Western blot. The results showed that 10% XHP-medicated serum had little effect on the cell viability, proliferation, apoptosis and cell cycle of U251 cells under hypoxia. Compared with the model group, 10% XHP-medicated serum at 1.0, 1.5 and 2.0 h significantly decreased the migration rate (P < 0.01) and the number of invading U251 cells (P < 0.01). 10% XHP-medicated serum at 2.0 h significantly suppressed the formation of VM tubular structures in U251 cells under the condition of hypoxia (P < 0.01). Western blot experiment showed that 10% XHP-medicated serum significantly down-regulated the expression of HIF-1α, VEGFA, phospho-VEGFR2, VE-cadherin, EphA2 and MMP14 proteins (P < 0.05). In conclusion, XHP could inhibit the formation of VM in human glioblastoma U251 cells to suppress the angiogenesis by down-regulating the HIF-1α/VEGFA/VEGFR2 signaling pathway.

ABSTRACT

OBJECTIVE To study the correlation of novel organic cation transporter 2 (OCTN2) with the chemosensitivity of prostate cancer cells to oxaliplatin. METHODS Tumor samples of patients receiving radical prostatectomy were collected, and OCTN2 protein was detected with immunohistochemistry; the primary cells of the specimen were cultivated to obtain prostate cancer cell line. Inductively coupled plasma mass spectrometry was used to detect the uptake of low concentration (0.1 μmol/L) of oxaliplatin by cancer cells. Real-time PCR and Western blot were used to detect the mRNA and protein expressions of OCTN2 in cancer cells; the prostate cancer cells with the highest and lowest expression of OCTN2 protein were selected, and IC50 of oxaliplatin to prostate cancer cells was analyzed by ATP-TCA method. The inhibitory rate of plasma peak concentration of oxaliplatin (50 μmol/L) to prostate cancer cells was detected by MTT assay. Spearman method was used to analyze the relationship of the uptake of oxaliplatin by prostate cancer cells with inhibitory rate of oxaliplatin to prostate cancer cells and 505916443@qq.com mRNA expressions of OCTN2. RESULTS OCTN2 was located on the membrane of cancer cells, and the uptake of zjdtztougao@163.com oxaliplatin by cancer cells was 0.283±0.264 (n=12)mRNA and protein expression of OCTN2 varied significantly among different cancer cells. The sensitivity of cancer cells with high expression of OCTN2 to oxaliplatin (IC50 of 4.61 μmol/L) was higher than that of cancer cells with lower expression of OCTN2 (IC50 of 26.23 μmol/L). The inhibitory rate of oxaliplatin to cancer cells was (25.4±10.8)% (n=12). There was a correlation between the uptake of oxaliplatin by prostate cancer cells and the inhibition rate of oxaliplatin to prostate cancer cells and mRNA expression of OCTN2 (P<0.05). CONCLUSIONS High-expressed OCTN2 may promote the uptake of oxaliplatin by prostate cancer cells, and its expression can serve as a reference for predicting the sensitivity of prostate cancer cells to oxaliplatin chemotherapy.

ABSTRACT

OBJECTIVE@#To compare the efficacy and muscle injury imaging between oblique lateral lumbar interbody fusion (OLIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of single-segment degenerative lumbar spinal stenosis.@*METHODS@#The clinical data of 60 patients with single-segment degenerative lumbar spinal stenosis who underwent surgical treatment from January 2018 to October 2019 was retrospectively analyzed. The patients were divided into OLIF groups and TLIF group according to different surgical methods. The 30 patients in the OLIF group were treated with OLIF plus posterior intermuscular screw rod internal fixation. There were 13 males and 17 females, aged from 52 to 74 years old with an average of (62.6±8.3) years old. And 30 patients in the TLIF group were treated with TLIF via the left approach. There were 14 males and 16 females, aged from 50 to 81 years old with an average of (61.7±10.4) years old. General data including operative time, intraoperative blood loss, postoperative drainage volume, and complications were recorded for both groups. Radiologic data including disc height (DH), the left psoas major muscle, multifidus muscle, longissimus muscle area, T2-weighted image hyperintensity changes and interbody fusion or nonfusion were observed. Laboratory parameters including creatine kinase (CK) values on postoperative 1st and 5th days were analyzed. Visual analogue scale(VAS) and Oswestry disability index(ODI) were used to assess clinical efficacy.@*RESULTS@#There was no significant difference in the operative time between two groups(P>0.05). The OLIF group had significantly less intraoperative blood loss and postoperative drainage volume compared to the TLIF group(P<0.01). The OLIF group also had DH better recovery compared to the TLIF group (P<0.05). There were no significant differences in left psoas major muscle area and the hyperintensity degree before and after the operation in the OLIF group (P>0.05). Postoperativly, the area of the left multifidus muscle and longissimus muscle, as well as the mean of the left multifidus muscle and longissimus muscle in the OLIF group, were lower than those in the TLIF group (P<0.05) .On the 1st day and the 5th day after operation, CK level in the OLIF group was lower than that in the TLIF group(P<0.05). On the 3rd day after operation, the VAS of low back pain and leg pain in the OLIF group were lower than those in the TLIF group (P<0.05). There were no significant differences in the ODI of postoperative 12 months, low back and leg pain VAS at 3, 6, 12 months between the two groups(P>0.05). In the OLIF group, 1 case of left lower extremity skin temperature increased after the operation, and the sympathetic chain was considered to be injured during the operation, and 2 cases of left thigh anterior numbness occurred, which was considered to be related to psoas major muscle stretch, resulting in a complication rate of 10% (3/30). In the TLIF group, one patient had limited ankle dorsiflexion, which was related to nerve root traction, two patients had cerebrospinal fluid leakage, and the dural sac was torn during the operation, and one patient had incision fat liquefaction, which was related to paraspinal muscle dissection injury, resulting in a complication rate of 13% (4/30). All patients achieved interbody fusion without cage collapse during the 6- month follow-up.@*CONCLUSION@#Both OLIF and TLIF are effective in the treatment of single-segment degenerative lumbar spinal stenosis. However, OLIF surgery has obviously advantages, including less intraoperative blood loss, less postoperative pain, and good recovery of intervertebral space height. From the changes in laboratory indexes of CK and the comparison of the left psoas major muscle, multifidus muscle, longissimus muscle area, and high signal intensity of T2 image on imaging, it can be seen that the degree of muscle damage and interference of OLIF surgery is lower than that of TLIF.

ABSTRACT

Objective:To evaluate the risk factors for adjacent vertebral compression fracture (AVCF) after fusion surgery of lumbar canal stenosis in the elderly.Methods:A retrospective cohort study was designed for 297 patients with lumbar canal stenosis who underwent fusion surgery in Hubei Provincial Hospital of Integrated Chinese and Western Medicine from January 2017 to December 2020. There were 42 males and 255 females, aged 68-85 years [(76.3±7.2)years]. The patients were divided into AVCF group ( n=67) and non-AVCF group ( n=230) according to with or without the occurrence of AVCF. The indicators recorded were the gender, age, body mass index, education level, number of combined basic diseases, course of the disease, preoperative bone mineral density, intraoperative bleeding volume, number of level fused during operation, postoperative blood transfusion volume, postoperative observation in the ICU, types of postoperative external fixation and time of external fixation. Univariate analysis was conducted to analyze the correlation between above risk factors and AVCF after fusion surgery of lumbar canal stenosis in the elderly. Multivariate Logistic regression analysis was used to determine the independent risk factors for the occurrence of AVCF in these patients. Results:In the univariate analysis, age, education level, preoperative bone mineral density, intraoperative bleeding volume, postoperative blood transfusion volume and postoperative observation in the ICU were correlated with AVCF after fusion surgery of lumbar canal stenosis in the elderly ( P<0.05 or 0.01), while there was no correlation of AVCF with gender, body mass index, number of combined basic diseases, course of the disease, number of level fused during operation, types of postoperative external fixation and time of external fixation (all P>0.05). Multivariate Logistic regression analysis showed that gender ( OR=4.02, 95% CI 1.35, 12.00, P<0.05), preoperative bone mineral density≤-2.5 SD ( OR=2.01, 95% CI 1.47, 2.75, P<0.01), intraoperative bleeding volume≥475 ml ( OR=1.01, 95% CI 1.00, 1.01, P<0.01) and postoperative blood transfusion volume≥434 ml ( OR=0.99, 95% CI 0.98, 1.00, P<0.01) were significantly associated with AVCF after fusion surgery of lumbar canal stenosis in the elderly.

ABSTRACT

OBJECTIVE@#To observe the hypoglycemic effect of electroacupuncture (EA) at "Tianshu" (ST 25) combined with metformin on rats with type 2 diabetes mellitus (T2DM) as well as its effect on expression of adenosine monophosphate activated protein kinase (AMPK) in liver and pancreas.@*METHODS@#Thirty-six male SD rats were randomly divided into a blank group (6 rats) and a model establishing group (30 rats). The rats in the model establishing group were fed with high-fat diet and treated with intraperitoneal injection of low-dose streptozotocin (STZ) to establish T2DM model. The rats with successful model establishment were randomly divided into a model group, a control group, a metformin group, an EA group and a combination group, 6 rats in each group. The rats in the EA group were treated with EA at "Tianshu" (ST 25), dense-disperse wave, 2 Hz/15 Hz in frequency and 2 mA in current intensity, 20 min each time. The rats in the metformin group were treated with intragastric administration of metformin (190 mg/kg) dissolved in 0.9% sodium chloride solution (2 mL/kg). The rats in the combination group were treated with EA at "Tianshu" (ST 25) and intragastric administration of metformin. The rats in the control group were treated with intragastric administration of 0.9% sodium chloride solution with the same dose. All the treatments were given once a day for 5 weeks. After the intervention, the body mass and random blood glucose were detected; the serum insulin level was detected by ELISA; the expression of AMPK and phosphorylated adenosine monophosphate activated protein kinase (p-AMPK) in liver and pancreas was detected by Western blot method; the expression of protein gene product 9.5 (PGP9.5) was detected by immunofluorescence.@*RESULTS@#①Compared with the blank group, the body mass in the model group was decreased (P<0.05); compared with the model group, the body mass in the EA group and the combination group was decreased (P<0.05); the body mass in the EA group and the combination group was lower than the metformin group (P<0.05). Compared with the blank group, the random blood glucose in the model group was increased (P<0.01); compared with the model group, the random blood glucose in the metformin group, the EA group and the combination group was decreased (P<0.01). The random blood glucose in the combination group was lower than the metformin group and the EA group (P<0.05). ②Compared with the blank group, the insulin level in the model group was decreased (P<0.05); compared with the model group, the insulin level in the metformin group, the EA group and the combination group was all increased (P<0.05). The insulin level in the combination group was higher than the metformin group and the EA group (P<0.05). ③Compared with the blank group, the protein expression of AMPK and p-AMPK in liver tissue was decreased (P<0.05), and the protein expression of AMPK and p-AMPK in pancreatic tissue was increased (P<0.05) in the model group. Compared with the model group, the protein expression of AMPK and p-AMPK in liver tissue in the metformin group, the EA group and the combination group was increased (P<0.05, P<0.01); the protein expression of AMPK in pancreatic tissue in the metformin group was increased (P<0.05); the protein expression of AMPK in pancreatic tissue in the EA group and the combination group was decreased (P<0.05); the protein expression of p-AMPK in pancreatic tissue in the metformin group, the EA group and the combination group was decreased (P<0.05). The protein expression of AMPK and p-AMPK in liver tissue in the combination group was higher than that in the metformin group and the EA group (P<0.05); the protein expression of AMPK in pancreatic tissue in the EA group and the combination group was less than that in the metformin group (P<0.05), and the expression of p-AMPK protein in pancreatic tissue in the combination group was less than that in the metformin group and the EA group (P<0.05). ④Compared with the blank group, the expression of PGP9.5 in pancreatic tissue in the model group was increased (P<0.01); compared with the model group, the expression of PGP9.5 in pancreatic tissue in the metformin group, the EA group and the combination group was decreased (P<0.05, P<0.01). The expression of PGP9.5 in pancreatic tissue in the EA group was lower than the metformin group and the combination group (P<0.05).@*CONCLUSION@#Electroacupuncture at "Tianshu" (ST 25) could promote the effect of metformin on activating AMPK in liver tissue of T2DM rats, improve the negative effect of metformin on AMPK in pancreatic tissue, and enhance the hypoglycemic effect of metformin. The mechanism may be related to the inhibition of pancreatic intrinsic nervous system.

ABSTRACT

OBJECTIVE@#To retrospectively analyze efficacy of single structure internal fixation and double structure internal fixation in the treatment of ipsilateral femoral shaft and neck fracture, and analyze their indications.@*METHODS@#From June 2015 to December 2020, 21 patients with ipsilateral femoral shaft and femoral neck fracture were treated, including 14 males and 7 females, aged 23 to 69 years old with an average of(38.1±12.9) years old. According to different femoral shaft fracture sites, some patients were fixed with cephalomedullary implant for both femoral neck and the femoral shaft(single structure, InterTan or PFNA Ⅱ), some patients were fixed with cannulated screws for the femoral neck and a retrograde locking nail for the femoral shaft (dual structure), and postoperative function and complications were recorded during follow-up. In 10 cases of single-structure fixation, the femoral necks were all basicervical fractures, and the femoral shaft fractures were located in the proximal isthmus;11 cases were double-structure fixation, 9 cases in 11 were basal type of femoral neck, 2 cases in 11 were neck type, and the femoral shaft fractures were located in the isthmus and the distal isthmus.@*RESULTS@#All patients were followed up for 12 to 27 months. No femoral head necrosis, deformity, delay or nonunion occurred in the patients with single-structure fixation, and no delayed union or nonunion occurred in femoral shaft fractures;At the final follow-up, Harris score of patients with single-structure fixation was 91.8±4.1, with 8 cases were excellent and 2 cases were good. The fractures of patients with dual-structure fixation achieved good union without femoral head necrosis, except 1 case of femoral shaft fracture had delayed union;At the final follow-up, Harris score of patients with dual-structure fixation was 92.4±5.9, 7 cases were excellent, 3 cases were good, and 1 case was fair.@*CONCLUSION@#Good reduction and fixation is the key to the treatment of such fractures. Both the single-structure fixation and the dual-structure fixation are good methods, and it should be selected according to the locations of femoral shaft and femoral neck fractures. Single-structure fixation is a good choice for femoral shaft fractures located at the proximal isthmus and basal femoral neck fractures. For isthmus and distal femoral shaft fractures combined with ipsilateral femoral neck fractures, dual-structure fixation is recommended.

ABSTRACT

Objective:To investigate the application value and treatment opportunity of single balloon enteroscopy in children with Peutz-Jeghers syndrome(PJS).Methods:A retrospective analysis was conducted on 33 children diagnosed with PJS in Hunan Children′s Hospital from January 2011 to September 2021.The patient′s age, gender, family history, clinical symptoms, enteroscopy examination and treatment, number of polyps, intraoperative and pos-toperative complications, surgical treatment, recurrence of surgery, and follow-up data were analyzed, and the chi- square test was used for statistical analysis. Results:A total of 33 PJS children aged (9.00±3.13) years, including 21 males and 12 females, were included.All of them received at least once single balloon enteroscopy test.The main manifestations of the children were black spots (33 cases) and multiple polyps in the digestive tract (31 cases). In all the 33 cases, black spots were distributed on lips.Some black spots were also found at the end of fingers (3 cases), at the end of foot toes(2 cases), and at the end of finger toes (6 cases). During the operation, 391 polyps were removed, most of which were jejunum polyps (37.08%, 145/391 polyps). Eleven children with PJS has intussusception, of which intestinal intussusception accounted for 90.91% (10/11 cases). Ten cases (30.30%, 10/33 cases) received surgical treatment, and 72.73% (8/11 cases) underwent surgery for acute refractory intussusception.One case had intestinal perforation and 2 cases were bleeding during the operation, and the 3 cases recovered completely after hemostatic clip sealing and surgical treatment.The incidence of hollow ileum polyps and giant polyps in children aged >8 years was higher than that in children aged ≤8 years[92.55% (149/161 polyps) vs.7.45%(12/161 polyps), 96.20%(76/79 polyps) vs.3.80% (3/79 polyps)]. The differences were statistically significant ( χ2=9.854, 8.711, all P<0.05). There was no significant difference in the incidence of intussusception among different age groups ( P>0.05). Among the 33 children with PJS, 57.58% (19/33 cases) had recurrence 1-3 years after operation, and no cases of cancer have been followed up so far. Conclusions:Intestinal polyps are common in children with PJS, and the application of single-balloon enteroscopy in children with PJS is reliable and safe.Children over 8 years old are more vulnerable to empty ileum polyps and giant polyps.Therefore, it is advised that children aged above 8 years with PJS should undergo at least once enteroscopy.

ABSTRACT

Neoadjuvant immunotherapy can reduce the risk of postoperative recurrence or distant metastasis in patients with resectable lung cancer, prolong the survival of patients, and has better efficacy compared to neoadjuvant chemotherapy. Existing clinical trials with a small sample size indicate that neoadjuvant immunotherapy combined with chemotherapy has a higher rate of major pathologic response compared to single-agent immunotherapy, but it is also accompanied by a higher incidence of treatment-related adverse events and a longer treatment cycle, which may lead to delayed surgery or increased risk of intraoperative complications. The selection of therapeutic regimens, surgical timing, efficacy evaluation, and other issues have not been determined. Several phase Ⅲ clinical studies of a single drug and combined regimen of neoadjuvant immunotherapy are ongoing, and the efficacy of neoadjuvant immunotherapy is expected to be further verified through follow-up data.

ABSTRACT

To explore the possible new mechanism of acupuncture in the treatment of diabetes mellitus type 2 (T2DM) based on the islet inflammatory response. Islet macrophages, pancreatic adipose cells and islet β cells all participate in the pathogenesis of T2DM, and the three could form a network interaction. Acupuncture could regulate the functional phenotype of islet macrophages, improve the ectopic deposition of pancreatic adipose and repair the function of islet β cells, and play a unique advantage of overall regulation. It is suggested that acupuncture can be a potential treatment strategy for T2DM.

ABSTRACT

OBJECTIVE@#To observe the effect of electroacupuncture (EA) at "Zusanli" (ST 36) combined with mosapride on gastric emptying rate and gastric motility in the rats with diabetic gastroparesis.@*METHODS@#Using random number table method, 68 male SD rats were divided into a blank group (12 rats) and a model establishment group (56 rats). In the model establishment group, the models of diabetic gastroparesis were established with intraperitoneal injection of streptozotocin combined with high-fat and high-sugar diet. Six weeks later, the successful rat models in the model establishment group were randomized into a model group, an EA group, a mosapride group and a combined treatment group, 12 rats in each one. In the EA group, EA was exerted at "Zusanli" (ST 36) (disperse-dense wave, 2 Hz/15 Hz in frequency, 2 mA in intensity) for 20 min. In the mosapride group, mosapride was intervened with intragastric administration (2 mg/kg). In the combined treatment group, electroacupuncture at "Zusanli" (ST 36) was combined with intragastric administration of mosapride. The intervention was given once daily in each group. There was 1 day at interval after 6-day intervention, consecutively for 5 weeks. At the end of intervention, the random blood glucose, gastric emptying rate and the data of gastric motility (average intra-gastric pressure, amplitude and frequency of gastric motility) were detected.@*RESULTS@#Compared with the blank group, blood glucose was increased in the model group (P<0.001). Blood glucose was reduced in the EA group, the mosapride group and the combined treatment group as compared with the model group separately (P<0.001, P<0.01), whereas, compared with the mosapride group, blood glucose was decreased in the combined treatment group (P<0.05). In comparison with the blank group, the gastric emptying rate, the average intra-gastric pressure and the amplitude of gastric motility were all decreased in the model group (P<0.001) and the frequency of gastric motility was increased (P<0.001). Gastric emptying rate, the average intra-gastric pressure and the amplitude of gastric motility were increased in the EA group, the mosapride group and the combined treatment group (P<0.01, P<0.05, P<0.001) and the frequency of gastric motility was decreased (P<0.001) as compared with the model group respectively. Compared with the EA group, the average intra-gastric pressure and the amplitude of gastric motility were increased in the combined treatment group (P<0.001). In comparison with the mosapride group, the gastric emptying rate, the average intra-gastric pressure, the amplitude and frequency of gastric motility in the combined treatment group, as well as the frequency of gastric motility in the EA group were all increased (P<0.05, P<0.001, P<0.01).@*CONCLUSION@#Electroacupuncture at "Zusanli" (ST 36) combined with intragastric administration of mosapride could regulate blood glucose and improve the gastric motility in the rats with diabetic gastroparesis. The effect is better than either simple electroacupuncture or mosapride.
