Progress in the treatment of central retinal artery occlusion / 国际眼科杂志(Guoji Yanke Zazhi)

Central retinal artery occlusion(CRAO)refers to occlusion of the central retinal artery(CRA), which acts as the primary blood supply to the inner neurosensory retina, and leads to an acute loss of vision and permanent visual disability. The natural history of visual prognosis in CRAO is generally poor. Despite a variety of treatment options have been studied, such as ocular massage, anterior chamber paracentesis, hyperbaric oxygen therapy(HBOT)and intra-arterial infusion of tissue plasminogen activator(tPA), but there is currently no evidence-based management strategies for the treatment of CRAO. Furthermore, the efficacy of all available managements is debatable and many have uncertain risks. This review will offer a summary of the currently known treatment options for CRAO and probe into their safety and efficacy on the prognosis of CRAO.

AIM: To explore a more convenient and accurate method for evaluating the anterior chamber angle width based on the Van Herick method.METHODS:A total of 58 patients(69 eyes)with age-related cataract who visited our hospital between January and December 2021 were included. They were divided into the chamber angle width ≥1/2 corneal thickness(CT)group(44 eyes of 37 cases)and <1/2CT group(25 eyes of 21 cases)according to the Van Herick method. The central anterior chamber depths and the peripheral anterior chamber angle degrees were measured by ultrasound biomicroscopy.RESULTS: There were statistically significant differences in central anterior chamber depth between the two groups(2.64±0.27 mm vs. 2.23±0.29 mm, P<0.01), and the differences of chamber angle degrees of quadrants of superior, temporal, inferior and nasal compared between two groups were all statistically significant(P<0.01). The difference of chamber angle degrees of quadrants of superior and inferior in chamber angle width ≥1/2CT group was not statistically significant(P>0.05), while the differences of chamber angle degrees of other quadrants were all statistically significant(P<0.05). The differences of chamber angle degrees of quadrants of superior and nasal, temporal and the chamber angle degrees of quadrants of inferior and temporal were all statistically significant in chamber angle width <1/2CT group(P<0.05).CONCLUSION: In the overall evaluation of the anterior chamber angle, it would be more simple, fast and accurate when evaluating the temporal chamber angle width and inferior quadrant of chamber angle width by using the Van Herick method under silt lamp.

Continuous and Intermittent Exercise Upregulates PGC-1α/ Irisin / BDNF Expression to Improve Obesity-induced Cognitive Impairment in Mice / 中国生物化学与分子生物学报

This study aimed to investigate the effects of exercise on prefrontal PGC-1α, Irisin, BDNF, oxidative stress, inflammation, and cognitive function in high-fat diet-induced obese mice, which may provide experimental evidence of exercise rehabilitation methods and target screening for obesity. Three-month-old male C57BL/ 6J wild-type mice were randomly divided into four groups: control, high-fat diet, high-fat diet with moderate intensity continuous training, and high-fat diet with high-intensity interval training group, with 10 mice in each group. The mice in the high-fat diet with moderate intensity continuous training group and the high-fat diet with high-intensity interval training group received 8 weeks of moderate-intensity continuous training or high-intensity interval training after 12-week high-fat feeding. Behavioral results showed that compared with the control group, reaction time of adhesive removal test was significantly increased (P<0. 01), and spontaneous alternation rate in Y-maze test and exploration time in the novel object recognition test were significantly decreased (P < 0. 01) in the high-fat diet group, indicating that high-fat diet led to cognitive dysfunction in mice. Results showed that compared with the control group, Nissl bodies dissolution and apoptosis were significantly increased (P<0. 01), levels of PGC-1α, Irisin, BDNF, IL-10, and T-SOD were significantly deceased (P<0. 05, P<0. 01), levels of IL-1β, TNF-α, NF-κB, cleaved Caspase-3, Bax/ Bcl-2, ROS, and MDA were significantly increased in the prefrontal lobe (P<0. 01), indicating that high-fat diet induced excessive inflammation, oxidative stress, and apoptosis, which were conducive to prefrontal lobe damage. Compared with the high-fat diet group, moderate intensity continuous or high-intensity interval training decresed reaction time of adhesive removal test (P<0. 01), increased spontaneous alternation rate of Y-maze test and exploration time of novel object recognition test (P<0. 05, P<0. 01), indicating that both continuous and interval training improved cognitive function in obese mice; meanwhile, Nissl bodies and levels of PGC-1α, Irisin, BDNF, IL-10, and T-SOD were significantly increased (P<0. 05, P<0. 01), and apoptosis and levels of IL-1β, TNF-α, NF-κB, cleaved Caspase-3, Bax/ Bcl-2, ROS, and MDA were significantly reduced in the prefrontal lobe (P<0. 01), indicating that both continuous and interval training alleviated obesity-induced inflammation, oxidative stress, and apoptosis in the prefrontal lobe. Both continuous and interval training significantly upregulated PGC-1α/ Irisin/ BDNF expression in the prefrontal lobe of obese mice, inhibited oxidative stress and inflammation, reduced apoptosis, and resulted in alleviating obesity-induced prefrontal lobe damage and cognitive dysfunction; morevover, interval training better than continuous.

Results A total of 290 356 person-times were screened for echinococcosis among residents at ages of 12 years and older in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 1 094 residents detected with cystic echinococcosis, and the detection of echinococcosis appeared a tendency towards a gradual decline over years (χ2 = 358.602, P < 0.001). A total of 32 931 person-times were screened for echinococcosis among children at ages of 12 years and older in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 296 children detected with echinococcosis, and the detection of echinococcosis appeared a tendency towards a gradual decline over years (χ2 = 267.673, P < 0.001). A total of 33 230 domestic dog stool samples were tested for Echinococcus coproantigens in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 1 777 Echinococcus coproantigens-positive samples tested, and the positive rate of Echinococcus coproantigens appeared a tendency towards a decline in domestic dogs over years (χ2 = 2 210.428, P < 0.001), while the positive rate of Echinococcus coproantigens showed a tendency towards a rise in domestic animals from 2016 to 2022 (χ2 = 37.745, P < 0.001). The positive rate of Echinococcus coproantigens remained relatively stable in stray dogs in Tianzhu Tibetan Autonomous County, Gansu Province from 2019 to 2022 (χ2 = 0.315, P = 0.575). A total of 10 973 sheep were screened for echinococcosis in Tianzhu Tibetan Autonomous County from 2007 to 2022, with 334 sheep detected with echinococcosis, and the detection of echinococcosis appeared a tendency towards a decline in sheep over years (χ2 = 53.579, P < 0.001); however, there was no significant change in the detection of echinococcosis during the period from 2015 through 2022 (χ2 = 1.520, P = 0.218). A total of 2 400 cattle were screened for echinococcosis in Tianzhu Tibetan Autonomous County from 2017 to 2022, with 231 cattle detected with echinococcosis, and the detection of echinococcosis showed a tendency towards a decline over years (χ2 = 5.579, P < 0.05). The awareness of echinococcosis control knowledge increased from 44.37% in 2007 to 94.00% in 2022 among residents at ages of 12 years and older and from 52.50% in 2007 to 92.50% in 2022 among children at ages of 12 years and older in Tianzhu Tibetan Autonomous County, respectively. Conclusions There has been a reduction in the detection of echinococcosis in humans and domestic animals and the positive rate of Echinococcus coproantigens in dogs and a rise in the awareness of the echinococcosis control knowledge following the implementation of the central government-funded echinococcosis control programme in Tianzhu Tibetan Autonomous County, Gansu Province; however, integrated echinococcosis control measures are still required for further control of the prevalence of echinococcosis.

Application effect analysis of lateral prone position ventilation in patients with acute respiratory distress syndrome / 中华危重病急救医学

OBJECTIVE@#To investigate the effect of lateral prone position ventilation in patients with acute respiratory distress syndrome (ARDS).@*METHODS@#A prospective control study was conducted. A total of 75 patients with moderate to severe ARDS admitted to the department of critical care medicine of Jingxian Hospital in Anhui province from January 2020 to December 2022 were selected as the research objects. According to the envelope method, the patients were divided into the lateral prone position ventilation group (38 cases) and the traditional prone position ventilation (PPV) group (37 cases), using lateral prone position ventilation and traditional PPV, respectively. The mechanical ventilation parameters were set according to the ARDS treatment guidelines and lung protective ventilation requirements in both groups, and the time of prone position for the first 3 times was not less than 16 hours per day. General data of patients were recorded, including heart rate (HR), mean arterial pressure (MAP), airway resistance and lung static compliance (Cst) before prone position (T0), 1 hour (T1), 4 hours (T2), 8 hours (T3), and before the end of prone position (T4), oxygenation index (PaO2/FiO2) before the first prone position (t0) and 12 hours (t1), 24 hours (t2), 48 hours (t3), and 72 hours (t4) after the intensive care unit (ICU) admission, as well as the incidence of pressure injury (PI) and vomiting, tracheal intubation time, and mechanical ventilation time. Repeated measures analysis of variance was used to compare the effects of different prone positions on patients before and after the prone position.@*RESULTS@#There were no significant differences in age, gender, body mass index (BMI), acute physiology and chronic health evaluation II (APACHE II), underlying diseases, HR, MAP, pH value, PaO2/FiO2, blood lactic acid (Lac), arterial blood pressure of carbon dioxide (PaCO2) and other general information between the two groups. The HR (intergroup effect: F = 0.845, P = 0.361; time effect: F = 1.373, P = 0.247; interaction: F = 0.245, P = 0.894), MAP (intergroup effect: F = 1.519, P = 0.222; time effect: F = 0.169, P = 0.954; interaction: F = 0.449, P = 0.773) and airway resistance (intergroup effect: F = 0.252, P = 0.617; time effect: F = 0.578, P = 0.679; interaction: F = 1.467, P = 0.212) of T0-T4 between two groups showed no significant difference. The Cst of T0-T4 between the two groups showed no significant difference in the intergroup effect (F = 0.311, P = 0.579) and the interaction (F = 0.364, P = 0.834), while the difference in the time effect was statistically significant (F = 120.546, P < 0.001). The PaO2/FiO2 of t0-t4 between the two groups showed no significant difference in the intergroup effect (F = 0.104, P = 0.748) and the interaction (F = 0.147, P = 0.964), while the difference in the time effect was statistically significant (F = 17.638, P < 0.001). The group factors and time factors were tested separately, and there were no significant differences in the HR, MAP, airway resistance, Cst, PaO2/FiO2 between the two groups at different time points (all P > 0.05). The Cst at T1-T4 and PaO2/FiO2 at t1-t4 in the two groups were significantly higher than those at T0/t0 (all P < 0.05). There were no significant differences in the tracheal intubation time [days: 6.75 (5.78, 8.33) vs. 7.00 (6.30, 8.45)] and mechanical ventilation time [days: 8.30 (6.70, 9.20) vs. 7.40 (6.80, 8.75)] between the lateral prone position ventilation group and the traditional PPV group (both P > 0.05). However, the incidences of PI [7.9% (3/38) vs. 27.0% (10/37)] and vomiting [10.5% (4/38) vs. 29.7% (11/37)] in the lateral prone position ventilation group were significantly lower than those in the traditional PPV group (both P < 0.05).@*CONCLUSIONS@#Both lateral prone position ventilation and traditional PPV can improve Cst and oxygenation in patients with moderate to severe ARDS. The two types of prone position have little influence on HR, MAP and airway resistance of patients, and there is no difference in the influence on tracheal intubation time and mechanical ventilation time of patients. However, the lateral prone position ventilation mode can reduce the incidence of PI and vomiting, and is worthy of clinical promotion and application.

Analysis of the diagnosis and treatment of 68 cases of iatrogenic ureteral stricture / 现代泌尿外科杂志

【Objective】 To investigate the common etiology, characteristics and treatment of iatrogenic ureteral stricture. 【Methods】 The clinical data of 226 patients with ureteral stricture repaired during May 2019 and Mar. 2022 were retrospectively analyzed, including 68 cases of iatrogenic ureteral stricture. According to the etiology, the patients were divided into urinary group and non-urinary group. 【Results】 There were 42 females and 26 males, aged 25 to 67 (average 49.0±10.4) years. Upper ureteral stricture was detected in 24 (35.3%) cases, who received oral mucosal repair of the ureter. Middle ureteral stricture was detected in 12 (17.6%) cases, who underwent ileal ureterography. Lower ureteral stricture was observed in 24 (35.3%) cases, who were treated with vesical wall flap ureteroplasty. Full-length stricture was observed in 8 (11.8%) cases,who were treated with ileal ureterography. There were significant differences in age, gender, stenosis side, stenosis location and length, surgical methods and types between patients in the urinary group and non-urinary group (P<0.05). During the follow-up of 8 to 20 (average 12.3±5.6) months, the symptoms and renal function of all patients improved, and no recurrence occurred. 【Conclusion】 Invasive endourological surgery is the most common cause of iatrogenic ureteral stenosis. Different treatment strategies should be adopted according to patients’ condition, time of diagnosis and location and length of ureteral injury.

Multi-modal synergistic quantitative analysis and rehabilitation assessment of lower limbs for exoskeleton / 生物医学工程学杂志

In response to the problem that the traditional lower limb rehabilitation scale assessment method is time-consuming and difficult to use in exoskeleton rehabilitation training, this paper proposes a quantitative assessment method for lower limb walking ability based on lower limb exoskeleton robot training with multimodal synergistic information fusion. The method significantly improves the efficiency and reliability of the rehabilitation assessment process by introducing quantitative synergistic indicators fusing electrophysiological and kinematic level information. First, electromyographic and kinematic data of the lower extremity were collected from subjects trained to walk wearing an exoskeleton. Then, based on muscle synergy theory, a synergistic quantification algorithm was used to construct synergistic index features of electromyography and kinematics. Finally, the electrophysiological and kinematic level information was fused to build a modal feature fusion model and output the lower limb motor function score. The experimental results showed that the correlation coefficients of the constructed synergistic features of electromyography and kinematics with the clinical scale were 0.799 and 0.825, respectively. The results of the fused synergistic features in the K-nearest neighbor (KNN) model yielded higher correlation coefficients ( r = 0.921, P < 0.01). This method can modify the rehabilitation training mode of the exoskeleton robot according to the assessment results, which provides a basis for the synchronized assessment-training mode of "human in the loop" and provides a potential method for remote rehabilitation training and assessment of the lower extremity.

Different processed products of Polygonati Rhizoma treat Alzheimer's disease in rats: urine metabolomics based on UPLC-Q/TOF-MS / 中国中药杂志

The study investigated the effects of different processed products of Polygonati Rhizoma(black bean-processed Polygonati Rhizoma, BBPR; stewed Polygonati Rhizoma, SPR) on the urinary metabolites in a rat model of Alzheimer's disease(AD). Sixty SPF-grade male SD rats were randomized into a control group, a model group, a donepezil group, a BBPR group, and a SPR group, with twelve rats in each group. Other groups except the control group were administrated with D-galactose injection(100 mg·kg~(-1)) once a day for seven weeks. The control group was administrated with an equal volume of normal saline once a day for seven consecutive weeks. After three weeks of D-galactose injection, bilateral hippocampal Aβ_(25-35) injections were performed for modeling. The rats were administrated with corresponding drugs(10 mL·kg~(-1)) by gavage since week 2, and the rats in the model and control group with an equal volume of double distilled water once a day for 35 continuous days. The memory behaviour and pathological changes in the hippocampal tissue were observed. The untargeted metabolites in the urine were detected by ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q/TOF-MS). Principal component analysis(PCA) and orthogonal partial least square-discriminant analysis(OPLS-DA) were employed to characterize and screen differential metabolites and potential biomarkers, for which the metabolic pathway enrichment analysis was conducted. The results indicated that BBPR and SPR increased the new object recognition index, shortened the escape latency, and increased the times of crossing the platform of AD rats in the Morris water maze test. The results of hematoxylin-eosin(HE) staining showed that the cells in the hippocampal tissue of the drug administration groups were closely arranged. Moreover, the drugs reduced the content of interleukin-6(IL-6, P<0.01) and tumor necrosis factor-α(TNF-α) in the hippocampal tissue, which were more obvious in the BBPR group(P<0.05). After screening, 15 potential biomarkers were identified, involving two metabolic pathways: dicoumarol pathway and piroxicam pathway. BBPR and SPR may alleviate AD by regulating the metabolism of dicoumarol and piroxicam.

Shenfu Injection alleviates sepsis-associated lung injury by regulating HIF-1α / 中国中药杂志

Shenfu Injection(SFI) is praised for the high efficacy in the treatment of septic shock. However, the precise role of SFI in the treatment of sepsis-associated lung injury is not fully understood. This study investigated the protective effect of SFI on sepsis-associated lung injury by a clinical trial and an animal experiment focusing on the hypoxia-inducing factor-1α(HIF-1α)-mediated mitochondrial autophagy. For the clinical trial, 70 patients with sepsis-associated lung injury treated in the emergency intensive care unit of the First Affiliated Hospital of Zhengzhou University were included. The levels of interleukin(IL)-6 and tumor necrosis factor(TNF)-α were measured on days 1 and 5 for every patient. Real-time quantitative polymerase chain reaction(RT-qPCR) was performed to determine the mRNA level of hypoxia inducible factor-1α(HIF-1α) in the peripheral blood mononuclear cells(PBMCs). For the animal experiment, 32 SPF-grade male C57BL/6J mice(5-6 weeks old) were randomized into 4 groups: sham group(n=6), SFI+sham group(n=10), SFI+cecal ligation and puncture(CLP) group(n=10), and CLP group(n=6). The body weight, body temperature, wet/dry weight(W/D) ratio of the lung tissue, and the pathological injury score of the lung tissue were recorded for each mouse. RT-qPCR and Western blot were conducted to determine the expression of HIF-1α, mitochondrial DNA(mt-DNA), and autophagy-related proteins in the lung tissue. The results of the clinical trial revealed that the SFI group had lowered levels of inflammatory markers in the blood and alveolar lavage fluid and elevated level of HIF-1α in the PBMCs. The mice in the SFI group showed recovered body temperature and body weight. lowered TNF-α level in the serum, and decreased W/D ratio of the lung tissue. SFI reduced the inflammatory exudation and improved the alveolar integrity in the lung tissue. Moreover, SFI down-regulated the mtDNA expression and up-regulated the protein levels of mitochondrial transcription factor A(mt-TFA), cytochrome c oxidase Ⅳ(COXⅣ), HIF-1α, and autophagy-related proteins in the lung tissue of the model mice. The findings confirmed that SFI could promote mitophagy to improve mitochondrial function by regulating the expression of HIF-1α.

In the probiotics group， the ratio of Firmicutes to Bacteroidetes decreased. In the TFN group， the abundance of Lactobacillus and uncultured Bacteroidetes significantly increased， while the abundance of Parabacteroides， Klebsiella， and Enterococcus significantly decreased （P＜0.05）. Compared with the TFN group， allopurinol group and the probiotics group showed elevated blood uric acid levels， abundance of Bacteroidetes， ADA and XOD levels in intestinal tissue， and GLUT9 mRNA expression. The relative abundance of Firmicutes， abundance of lactobacilli， and ABCG2 mRNA expression significantly decreased. The probiotics group showed elevated GLUT9 protein expression in intestinal tissue. The probiotics group and the allopurinol plus probiotics group showed significantly higher scores for spleen deficiency syndrome in mice， and lower levels of butyric acid in mouse intestinal lavage fluid. The allopurinol group showed decreased numbers of OTUs in mouse intestinal flora， decreased abundance of proteobacteria， and butyric acid levels in intestinal lavage fluid. The allopurinol group also showed decreased ABCG2 protein expression in intestinal tissue， increased acetic acid levels in intestinal lavage fluid， increased abundance of Klebsiella， and significantly elevated GLUT9 protein expression （P＜0.05）. ConclusionsThe treatment of HUA with TFN may be associated with the regulation of intestinal probiotics （such as lactobacilli） and pathogenic bacteria （such as Klebsiella）， as well as the production of bacterial metabolites such as acetic acid and butyric acid. It may also involve reducing the expression of ADA and XOD in the intestines， decreasing intestinal uric acid production， upregulating the expression of intestinal epithelial urate transporter ABCG2， downregulating GLUT9 expression， and promoting intestinal uric acid excretion. These factors are related to the syndrome of spleen deficiency with exuberance of dampness.

Diagnostic efficacy comparison between CLLflow score and Moreau score for chronic lymphocytic leukemia / 中华检验医学杂志

Objective:To explore the diagnostic efficacy difference and clinical diagnostic value of chronic lymphocytic leukemia flow (CLLflow) score and Moreau score (MS) in the diagnosis of chronic lymphocytic leukemia (CLL).Methods:According to the latest international and national diagnosis criteria for CLL, 133 patients with B-cell chronic lymphoproliferative diseases and uncertain immunophenotypes (B-CLPD), diagnosed by Zhengzhou Jinyu Comprehensive Haematological Pathology Diagnosis Centre from March 2020 to May 2021, were included in this study. Above patients were divided into the CLL group ( n=83) and non-CLL group ( n=50). The expression of clusters of differentiation (CD)5, CD10, CD20, CD19, κ light chain, λ light chain, FMC7, CD23, CD22, surface immunoglobulin M, CD200 and CD79 were detected by flow cytometry, and CLLflow score and MS score were calculated respectively according to the scoring rules. A fourfold table was used to compare the diagnostic efficacy of the two scoring systems, and the Kappa test and McNemar test were used to compare the consistency and superiority of the systems. Results:The rate of negative and positive CLLflow score were 4.8% (4/83) and 95.2% (79/83) in the CLL group and were 80.0% (40/50) and 20.0% (10/50) in the non-CLL group, and respectively (both P<0.001). The MS score (≤2, =3 and≥4) was 1.2% (1/83), 10.8% (9/83) and 88.0% (73/83) in the CLL group and was 86.0% (43/50), 14.0% (7/50) and 0 in the non-CLL group, there were significant statistical difference between the two groups ( P<0.001). The sensitivity, specificity, positive predictive value and negative predictive value of the CLLflow score were 95.2% (79/83), 80.0% (40/50), 88.8% (79/89) and 90.9% (40/44), respectively and those of MS score were 98.8% (82/83), 86.0% (43/50), 92.1% (82/89) and 97.7% (43/44) respectively. The overall coincidence rate, positive and negative coincidence rate between the CLLflow score and MS score were 91.0% (121/133), 93.3% (83/89) and 86.4% (38/44) respectively. Besides, the McNeamr dominance test presented no significant difference ( P>0.05) and high consistency (Kappa=0.796) between the two scoring systems. With MS≤2 and MS≥4, the sensitivity and the specificity of the MS score were 100% (73/73) and 97.7% (43/44) respectively, and for the CLLflow score, the sensitivity and the specificity were 97.3% (71/73) and 86.4% (38/44) in this MS range. With MS = 3, the sensitivity and specificity of the MS score were 100% (9/9) and 0 (0/7), and CLLflow was 88.9% (8/9) and 57.1% (4/7). Conclusions:The diagnostic efficacy is similar and presents high consistency between the CLLflow score and MS score in CLL diagnosis. For CLL patients with MS = 3, the specificity of MS is relatively low, combined assessment with CLLflow score could improve the diagnosis efficacy for CLL in these patients.

Diagnosis and treatment progress of stage Ⅲ resectable/potentially resectable NSCLC / 中华胸心血管外科杂志

Treatment of stage Ⅲ NSCLC is challenging, and the best treatment strategy is still controversial. The emergence of new therapeutic agents and philosophy also continues to redefine the range of resectable/ potentially resectable NSCLC. Resectable N2-stage Ⅲ lymph nodes are usually scattered with well-defined margins and no adhesions to surrounding structures. Neoadjuvant therapy followed by surgery has lower local recurrence rate compared to radical radiotherapy. According to current guidelines, surgical treatment is not recommended for N3-stage Ⅲ NSCLC. However, for regional N3 disease with continuous response to chemotherapy, after careful selection, surgery may worth a try. The efficacy of immunotherapy in locally advanced lung cancer has been confirmed in many prospective clinical trials. Neoadjuvant immunotherapy significantly improves major pathological remission rates and pathological complete remission rates, which allows these downstaging patients have the chance to receive surgery and thus improve their long-term prognosis. For efficacy assessment of neoadjuvant immunotherapy, pathological biopsy is more reliable than CT. In conclusion, the progress in multimodality neoadjuvant therapy will provide more surgical opportunities and better long-term prognosis for patients with potentially resectable stage Ⅲ NSCLC.

Liver transplantation for liver metastasis of unresectable rectal cancer: one case report / 中华器官移植杂志

This report described one case of applying liver transplantation (LT) in for liver metastases of unresectable rectal cancer.The recipient had multiple intrahepatic metastases upon a diagnosis of colorectal cancer.FOLFOX chemotherapy plus bevacizumab targeted therapy were offered after a resection of primary lesion.Two years later, intrahepatic metastases expanded while no extrahepatic metastasis or in situ recurrence was noted.After LT, tacrolimus + sirolimus immunosuppression regimen and chemotherapy of rhatitrexed were prescribed.Tumor recurred at 3 years after LT and the survival time was 6 years.For patients with unresectable liver metastases of colorectal cancer, LT in the absence of orthotopic recurrence and other distant metastases may improve patient quality-of-life and achieve better outcomes.

Clinical characteristics and prognosis of duodenal neuroendocrine neoplasms / 中华普通外科杂志

Objective:To investigate the clinical characteristics and prognosis of duodenal neuroendocrine neoplasms.Methods:The clinical data of 35 patients with duodenal neuroendocrine neoplasms admitted to Union Hospital, Tongji Medical College, Huazhong University of Science & Technology from Jan 2012 to Dec 2021 were retrospectively analyzed. The differences of clinical characteristics between periampullary and non-periampullary duodenal neuroendocrine neoplasms were analyzed. Kaplan-Meier curve was used for survival analysis, and the clinical factors affecting the prognosis were analyzed.Results:Of the 35 patients, 30 underwent tumor resection, 7 (23%) developed different degree of complications after operation and were improved and discharged after intervention. A total of 5 patients died during the follow-up period. Only 1 of 30 patients who underwent tumor resection died 30 months after operation due to disease progression, and the others had no recurrence or metastasis. Univariate analysis showed that tumor size, tumor grade, and tumor location were associated with the prognosis of patients (all P<0.05), and multivariate analysis showed that patients with tumors located.Away from the ampulla had a significantly better prognosis than those located around the duodenal ampulla ( P<0.01). Conclusions:Patients with duodenal neuroendocrine neoplasms have a good prognosis after complete resection; patients with duodenal neuroendocrine neoplasms located around the ampulla of Vater have a relatively poor prognosis compared with those away from the area of ampulla.

Clinical efficacy of neoadjuvant chemotherapy combined with radical surgery for elderly patients with locally advanced gastric cancer / 中华普通外科杂志

Objective:To evaluate the safety and feasibility of neoadjuvant chemotherapy (NACT) combined with radical surgery for elderly patients with locally advanced gastric cancer (LAGC).Methods:One hundred and fourty eight patients with LAGC after NACT and gastrectomy between 2012 and 2020 were retrospectively reviewed. They were divided into two groups: (1) <65 years old (111 cases) and (2) ≥65 years old (37 cases) and their clinicopathological and prognostic data were compared.Results:There was no significant difference between the two groups in the incidence of hematological complications such as anemia ( χ2=0.235, P=0.628), leukopenia ( χ2=0.613, P=0.434), neutropenia ( χ2=0.011, P=0.918) and thrombocytopenia ( χ2=0.253, P=0.615) and non-hematological complications such as nausea ( χ2=0.092, P=0.762), vomiting ( χ2=0.166, P=0.683), diarrhea ( χ2=0.015, P=0.902) and mucositis ( χ2=0.199, P=0.766) due to NACT. There were no statistical differences between the older patients and the younger in operation duration ( t=0.270, P=0.604), intraoperative bleeding ( t=1.140, P=0.250) and R 0 resection rate ( χ2=0.105, P=0.750). The incidence of postoperative complications was 25.2% and 37.8% in the younger patients and the olders ( χ2=2.172, P=0.141). Pleural effusion ( χ2=7.007, P=0.008) and pulmonary infection ( χ2=10.204, P=0.001) was significantly higher in the older patients than in the youngers. The 3-year progression-free survival rate ( t=0.494, P=0.482) and 3-year overall survival rate ( t=0.013, P=0.908) were comparable between the two groups. Conclusions:NACT combined with radical surgery is safe and effective in elderly patients with LAGC, except for higher perioperative pulmonary-related complications.
