Long-term efficacy and safety of Huangqi ()-based Traditional Chinese Medicine in diabetic peripheral neuropathy: a Meta-analysis of randomized controlled trials.

OBJECTIVE: To assess the long-term effectiveness of Huangqi (Radix Astragali Mongolici, HQ)-based Traditional Chinese Medicine (TCM) in the treatment of diabetic peripheral neuropathy (DPN). METHODS: Nine databases were searched to retrieve available randomized controlled trials that compared HQ-based TCM and Western Medicines in the treatment of DPN. The methodological quality of the included studies was assessed using the Cochrane bias risk tool, and RevMan 5.4 was used for data analysis. The effect estimates of interest were risk ratio (RR), mean difference (MD) or standardized mean difference (SMD) with 95% confidence interval (CI). RESULTS: The results from 48 available studies assessing 3759 patients demonstrated that cases administered HQ-based TCM [RR = 1.30, 95% CI (1.21, 1.40), P < 0.000 01] or HQ-based TCM combined with Western Medicines [RR = 1.25, 95% CI (1.19, 1.31), P < 0.000 01] exhibited higher total efficacy rates than individuals who received Western Medicine alone. The results showed that the HQ-based TCM group had decreased Toronto Clinical Scoring System scores [MD =－1.50, 95% CI (－1.83, －1.17), P < 0.000 01], and reduced serum interleukin 6 [SMD = －0.57, 95% CI (－0.87, －0.27), P = 0.0002] and tumor necrosis factors-α levels [SMD = －0.60, 95% CI (－0.95, －0.25), P = 0.0009]. In addition, both HQ-based TCM and HQ-based TCM combined with Western Medicine increased nerve conduction velocity and decreased glycaemia compared with Western Medicine alone. In terms of blood lipids, oxidative stress and adverse drug reactions, there were no significant differences between the HQ-based TCM groups and the Western Medicine control group. CONCLUSION: The current Meta-analysis revealed that HQ-based TCM yields higher efficacy and safety than Western Medicine alone for the treatment of DPN, although further well-designed RCTs are required to validate these findings.

Clinical characteristics and significance of the supraspinatus fragment in proximal humeral fractures / 中华骨科杂志

Objective:To investigate the clinical characteristics and significance of supraspinatus fragments in proximal humerus fractures.Methods:A total of 210 patients with proximal humerus fractures who underwent surgical treatment in the Department of Orthopaedic and Trauma Surgery, Affiliated Hospital of Yunnan University from July 2016 to December 2020 were retrospectively analyzed. There were 91 males and 119 females, aged 52.4±11.3 years (range, 18-87 years). Preoperatively, the shoulder joint X-ray, CT and 3D reconstruction, and MRI were evaluated for the presence of a small fracture mass on the lateral side of the interarticular sulcus and an "M" shaped fracture mass at the interarticular sulcus. Intraoperative observation, management, postoperative functional exercise and follow-up were performed by the same group of doctors. Postoperative outpatient review was performed at 2, 4, 6, 12, and 24 weeks, shoulder joint X-ray and CT were taken at 2, 6, and 24 weeks to observe the presence of subacromial displaced bone mass. Constant-Murley scale was used to assess shoulder joint function.Results:All 210 patients completed the surgery successfully, and none of them had vascular, nerve or ligament injuries during the operation. According to Neer's classification: 59 cases of two-part humeral greater tuberosity fractures, 36 cases of two-part humeral surgical neck fractures, 50 cases of three-part humeral greater tuberosity fractures, and 65 cases of four-part proximal humeral fractures. 61.0% (128/210) of the patients showed the presence of a supraspinatus fragment on preoperative imaging, including 42 two-part humeral greater tuberosity fractures, 1 two-part humeral surgical neck fracture, and 31 three-part humeral greater tuberosity fractures with a small lateral fracture mass over the intertubular groove; 54 four-part proximal humeral fractures had an "M" shaped fracture mass containing the intertubular groove. All patients were followed up for 11.8±2.4 months (range, 6-20 months). Postoperative X-ray showed that all fractures healed, and the healing time was 3.4±0.3 months (range, 3-5 months). The Constant-Murley scale of the shoulder joint was 86.3±11.5 (range, 61-100).Conclusion:Supraspinatus fragments are more common in proximal humerus fractures. Proper recognition and management of supraspinatus fragments can help understand the mechanism of proximal humeral fracture occurrence, the relationship between fracture displacement and rotator cuff injury, reduce the incidence of postoperative complications, and improve the shoulder joint function.

Objective: To examine the safety and effectiveness of laparoscopic individualized surgical treatment for chronic traumatic diaphragmatic hernia (CTDH). Methods: The clinical data and follow-up data of 29 CTDH cases admitted to the Qilu Hospital of Shandong University or the First Affiliated Hospital of Shandong First Medical University from June 2015 to January 2023 were retrospectively analyzed. There were 21 males and 8 females, aged (49.4±17.8) years (range: 19 to 79 years). The main clinical manifestations were symptoms of the digestive system and respiratory system, and only 4 cases were asymptomatic. All patients received laparoscopic treatment (conversion to open surgery was not excluded). Intraoperative exploration (location of the hernia, contents of the hernia, diameter of the hernia ring), surgical conditions (surgical repair plan, operation time, blood loss, postoperative complications) and postoperative follow-up were analyzed and discussed. Results: Laparoscopic repair was successfully completed in 27 cases, including simple suture in 6 cases, suture and patch repair in 17 cases, the anterior abdominal wall muscle flap reversal suture and patch repair of in 3 cases, and patch bridge repair in 1 case. The operation time was (112.8±44.7) minutes (range: 60 to 200 minutes). The amount of bleeding (M(IQR)) was 35 (58) ml (range: 10 to 300 ml). The other 2 patients were converted to laparotomy. Except for one patient with transverse colon strangulation necrosis who died of aggravated pulmonary infection after surgery, the remaining 28 patients were discharged successfully. The follow-up time was 36 (24) months (range: 1 to 60 months). During the follow-up period, only two patients had occasional left upper abdominal discomfort. Twenty-seven patients with left diaphragmatic hernia had no recurrence, and the symptoms of 1 patient with right diaphragmatic hernia were relieved. Conclusion: Customized laparoscopic surgical repair for CTDH according to the location and size of the diaphragmatic defect can achieve good surgical results.

Saliva microbiota and metabolite in individuals with caries or periodontitis / 中华口腔医学杂志

Objective: To detect and analyze the characteristics of oral microbiota in species composition, function and metabolism among caries, periodontitis and oral healthy individuals, hunting for the microbiome-derived biomarkers with specificity and sensitivity to estimate the occurrence of these two diseases. Methods: Saliva samples were collected from 10 patients with high caries risk [decayed-missing-filled teeth (DMFT)≥6, HC group] in Department of Endodontics, 10 patients with periodontitis of grade Ⅱ A-Ⅲ C (PG group) in Department of Periodontology and 10 oral healthy individuals (HH group) from School of Stomatology, The Fourth Military Medical University during from March 2022 to June 2022. A baseline examination was conducted on all participants, including their oral conditions of caries and periodontal health. Metagenomic sequencing (Illumina PE150 platform) and liquid chromatography-mass spectrometry were used to detect microorganisms and their metabolites in the samples respectively. The sequencing data were analyzed to obtain the information of microbial taxonomic composition, functional genes and metabolites in each group of samples. The basic oral conditions and saliva samples of subjects in each group were evaluated and collected by the same professional endodontist. Results: There were no significant difference in baseline characteristics such as age and sex among the subjects in each group (P>0.05). DMFT in HC group (9.0±1.7) was significantly higher than that in HH group (0) and PG group (0) (F=243.00, P<0.001). Sequencing data analysis showed that the taxonomic compositions of salivary microbiota in each group were mainly Firmicutes, Bacteroidetes, Proteobacteria, Actinobacteria and Fusobacteria at the phylum level, and Streptococcus, Neisseria, Rothia, Prevotella at the genus level. Differential analysis showed that, compared with the HH group, HC group and PG group had significant differences in taxonomic composition (P<0.05), and the most significant among them was Prevotella. At the species level, Prevotella pallens was the most significant change in HC group, and Porphyromonas gingivalis in PG group. Metabolite analysis showed that there were significant differences in metabolites between HC group and PG group. The results showed that, compared with the HH group, the most significant metabolite change was 3-hydroxy-1, 5-diphenylpentan-1-one in HC group (P=0.001) and N1 acetylspermine in PG group (P=0.002) respectively. Compared with the PG group, the metabolite of HC group with the most significant difference is D-glucosamine 6-phosphate (P=0.006). The metabolism gene function analysis showed that, the enrichment of carbohydrate metabolism related genes was highest in HC group, followed with HH group, and it was lowest in PG group. In addition, compared with the HH group, the abundance of functional genes related to glucose metabolism, such as ABC transporter and phosphotransferase system, were significantly decreased in PG group (P<0.05), but significantly increased in HC group (P<0.05). Conclusions: There is a significant correlation between the alternation of carbohydrate metabolism of salivary microbiota with the occurrence of caries and periodontitis. In the future, Prevotella pallens and 3-hydroxy-1, 5-diphenylpentan-1-one may be the potential biomarkers of caries; while Porphyromonas gingivalis and N1 acetylspermine work in the predictions of periodontitis.

Analysis of the causes of long-standing pelvic anterior sacral space infection and discussion of management techniques / 中华肿瘤杂志

Objective: To investigate the causes and management of long-term persistent pelvic presacral space infection. Methods: Clinical data of 10 patients with persistent presacral infection admitted to the Cancer Hospital of Zhengzhou University from October 2015 to October 2020 were collected. Different surgical approaches were used to treat the presacral infection according to the patients' initial surgical procedures. Results: Among the 10 patients, there were 2 cases of presacral recurrent infection due to rectal leak after radiotherapy for cervical cancer, 3 cases of presacral recurrent infection due to rectal leak after radiotherapy for rectal cancer Dixons, and 5 cases of presacral recurrent infection of sinus tract after adjuvant radiotherapy for rectal cancer Miles. Of the 5 patients with leaky bowel, 4 had complete resection of the ruptured nonfunctional bowel and complete debridement of the presacral infection using an anterior transverse sacral incision with a large tipped omentum filling the presacral space; 1 had continuous drainage of the anal canal and complete debridement of the presacral infection using an anterior transverse sacral incision. 5 post-Miles patients all had debridement of the presacral infection using an anterior transverse sacral incision combined with an abdominal incision. The nine patients with healed presacral infection recovered from surgery in 26 to 210 days, with a median time of 55 days. Conclusions: Anterior sacral infections in patients with leaky gut are caused by residual bowel secretion of intestinal fluid into the anterior sacral space, and in post-Miles patients by residual anterior sacral foreign bodies. An anterior sacral caudal transverse arc incision combined with an abdominal incision is an effective surgical approach for complete debridement of anterior sacral recalcitrant infections.

Elucidating the molecular determinants in the process of gastrin C-terminal pentapeptide amide end activating cholecystokinin 2 receptor by Gaussian accelerated molecular dynamics simulations.

Gastrin plays important role in stimulating the initiation and development of many gastrointestinal diseases through interacting with the cholecystokinin 2 receptor (CCK2R). The smallest bioactive unit of gastrin activating CCK2R is the C-terminal tetrapeptide capped with an indispensable amide end. Understanding the mechanism of this smallest bioactive unit interacting with CCK2R on a molecular basis could provide significant insights for designing CCK2R antagonists, which can be used to treat gastrin-related diseases. To this end, we performed extensive Gaussian accelerated molecular dynamics simulations to investigate the interaction between gastrin C-terminal pentapeptide capped with/without amide end and CCK2R. The amide cap influences the binding modes of the pentapeptide with CCK2R by weakening the electrostatic attractions between the C-terminus of the pentapeptide and basic residues near the extracellular domain in CCK2R. The C-terminus with the amide cap penetrates into the transmembrane domain of CCK2R while floating at the extracellular domain without the amide cap. Different binding modes induced different conformational dynamics of CCK2R. Residue pairs in CCK2R had stronger correlated motions when binding with the amidated pentapeptide. Key residues and interactions important for CCK2R binding with the amidated pentagastrin were also identified. Our results provide molecular insights into the determinants of the bioactive unit of gastrin activating CCK2R, which would be of great help for the design of CCK2R antagonists.

Objective: To explore the efficacy and safety of percutaneous transluminal pulmonary angioplasty (PTPA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH). Methods: This prospective single arm study included 19 CTEPH patients (7 male, age(56.3±12.5)years) admitted to Wuhan Asia Heart Hospital from January 2017 to June 2019 and received PTPA interventional therapy. Baseline data, including age, sex, WHO functional class, 6-minute walk distance (6MWD), NT-proBNP, right heart catheterization values, were collected. Patients received single or repeated PTPA. Number of dilated vessels from each patient was analyzed, patients were followed up for 24 weeks and right heart catheterization was repeated at 24 weeks post initial PTPA. All-cause death, perioperative complications, and reperfusion pulmonary edema were reported. WHO functional class, 6MWD, NT-proBNP, right heart catheterization values were compared between baseline and at 24 weeks follow up. Results: Nineteen CTEPH patients received a total of 56 PTPA treatments. The pulmonary artery pressure (mPAP) decreased from (40.11±7.55) mmHg (1 mmHg=0.133 kPa) to (27.53±4.75) mmHg (P<0.001), and the total pulmonary resistance (TPR) decreased from (13.00±3.56) Wood U to (5.48±1.56) Wood U (P<0.001), cardiac output increased from (3.19±0.63) L/min to (5.23±0.94) L/minutes (P<0.01) at 24 weeks post PTPA. The WHO functional class improved significantly (P<0.001), 6MWD increased from (307.08±129.51) m to (428.00±112.64) m (P=0.002), the NT-proBNP decreased at 24 weeks post PTPA (P=0.002). During the follow-up period, there was no death; hemoptysis occurred in 4 patients during the operation, none of which resulted in serious adverse clinical consequences. One patient developed reperfusion pulmonary edema and recovered after treatment. Conclusion: PTPA treatment is safe and can significantly improve the hemodynamics and WHO functional class of patients with CTEPH.

Clinical features and survival in Takayasu's arteritis-associated pulmonary hypertension: a nationwide study.

AIMS: This study aimed to assess the clinical characteristics and long-term survival outcome in patients with Takayasu's arteritis-associated pulmonary hypertension (TA-PH). METHODS AND RESULTS: We conducted a nationally representative cohort study of TA-PH using data from the National Rare Diseases Registry System of China. Patients with pulmonary artery involvement who fulfilled the diagnostic criteria of Takayasu's arteritis and pulmonary hypertension were included. The primary outcome was the time from diagnosis of TA-PH to the occurrence of all-cause death. Between January 2007 and January 2019, a total of 140 patients were included, with a mean age of 41.4 years at diagnosis, and a female predominance (81%). Patients with TA-PH had severely haemodynamic and functional impairments at diagnosis. Significant improvements have been found in N-terminal pro-B-type natriuretic peptide (NT-proBNP) and haemodynamic profiles in patients with TA-PH receiving drugs approved for pulmonary arterial hypertension. The overall 1-, 3-, and 5-year survival rates in TA-PH were 94.0%, 83.2%, and 77.2%, respectively. Predictors associated with an increased risk of all-cause death were syncope [adjusted hazard ratio (HR) 5.38 (95% confidence interval 1.77-16.34), P = 0.003], NT-proBNP level [adjusted HR 1.04 (1.03-1.06), P < 0.001], and mean right atrial pressure [adjusted HR 1.07 (1.01-1.13), P = 0.015]. CONCLUSION: Patients with TA-PH were predominantly female and had severely compromised haemodynamics. More than 80% of patients in our cohort survived for at least 3 years. Medical treatment was based on investigators' personal opinions, and no clear risk-to-benefit ratio can be derived from the presented data.

[Effect of calorie-enriched formula on postoperative catch-up growth in infants with cyanotic congenital heart disease: a propective randomized controlled study].

OBJECTIVE: To study the effect of calorie-enriched formula on postoperative catch-up growth in infants with cyanotic congenital heart disease (CHD). METHODS: A total of 100 infants with cyanotic CHD who underwent surgical operation from January to December, 2017, were randomly divided into a high-calorie group (receiving calorie-enriched formula after surgery) and a conventional group (receiving standard formula after surgery), with 50 infants in each group. All infants were followed up for 6 months. The observation indices included body height, body weight, prealbumin, and N-terminal pro-brain natriuretic peptide before surgery, at the time of ventilator weaning and extubation after surgery, and at 1, 3, and 6 months after surgery. Height-for-age Z-score (HAZ), weight-for-age Z-score (WAZ), and weight-for-height Z-score (WHZ) were also assessed. Adverse reactions were recorded for both groups. RESULTS: There were 25 cases (50%) and 21 cases (42%) of malnutrition in the high-calorie group and the conventional group respectively before surgery (P > 0.05). The nutritional status of the two groups improved 6 months after surgery (P < 0.05). At 6 months after surgery, compared with the conventional group, the high-calorie group had a lower proportion of infants with malnutrition (18% vs 36%, P < 0.05) and also a lower proportation of infants with a WAZ score of < -2 (P < 0.05). The infants with malnutrion in the high-calorie group had higher HAZ, WAZ, and WHZ than those in the conventional group (P < 0.05). No gastrointestinal intolerance was observed in both groups during hospitalization. CONCLUSIONS: Compared with the standard formula, calorie-enriched formula can better help with postoperative catch-up growth in infants with cyanotic CHD.

Gender Was Associated with Depression but Not with Gastrointestinal Dysfunction in Patients with Parkinson's Disease.

OBJECTIVE: To investigate the association between gender and gastrointestinal (GI) dysfunctions, as well as gender and other motor symptoms/nonmotor symptoms, in a sample of PD patients. METHODS: 186 patients with PD were recruited into this study and divided into male PD group (M-PD) and female PD group (FM-PD). Demographic and PD-related clinical information of the participants were collected by the same neurologist. PD patients were objectively assessed by a spectrum of rating scales of motor symptoms and nonmotor symptoms (including GI dysfunctions). The data were analyzed by SPSS 20 statistical software. RESULTS: Totally 95 cases (51.08%) were in the M-PD group and 91 cases (48.92%) in the FM-PD group. There were no significant differences in age, BMI, and lifestyles between the two groups (P > 0.05). Males had higher educational level (P = 0.002). Females were more likely to have early satiety and loss of appetite (P = 0.025, P = 0.001). There were no significant differences in LED disease duration, age of motor symptoms onset, types of motor symptoms onset, location of motor symptoms onset, and phenotype of motor symptoms between the two groups (P > 0.05). Females had significantly higher UPDRS-III and HAMD scores than males (P = 0.037, P = 0.034). There were no significant differences in PQSI, ESS, RLS, RBD, HAMA, HAMD, and MoCA scores between the two groups. Gender was associated with HAMD (OR = 0.682, P = 0.019). CONCLUSIONS: Gender is a risk factor for depression, but not for GI dysfunctions in patients with PD.

The value of neck circumference for identifying metabolic syndrome in type 2 diabetes / 中国医师进修杂志

Objective:To investigate the value of neck circumference (NC) for identifying metabolic syndrome (MS) in patients with type 2 diabetes.Methods:a total of 413 type 2 diabetic patients (188 male and 225 female) in Qinhuangdao Chinese Medicine Hospital from August 2018 to July 2019 were recruited. Waist circumference (WC), NC and metabolic indicators were measured. The association between WC, NC and metabolic indicators was explored. Area under the curve (AUC) was used to evaluate the abilities of NC.Results:The average age of male was (55.35 ± 14.15) years, and the detection rate of MS was 74.47% (140/188). The average age of female was (60.19 ± 10.29) years, and the detection rate of MS was 71.11% (160/225). In male group, WC showed a negative correlation with age and high density lipoprotein-cholesterol (HDL-C) ( P<0.05); NC showed a negative correlation with glycated hemoglobin, total cholesterol (TC) and HDL-C ( P<0.05), and a positive correlation with diastolic blood pressure (DBP) ( P<0.05). In female group, WC showed a positive correlation with fasting plasma glucose (FPG) and systolic blood pressure (SBP), and a negative correlation with HDL-C; NC showed a positive correlation with FPG and SBP. WC and HC were good indexes for identifying metabolic syndrome in type 2 diabetes (WC: AUC male 0.862, female 0.870; NC: AUC male 0.745, female 0.752). After applying the ROC analysis, neck circumferences ≥ 34.5 cm in males and ≥ 31.75 cm in females were determined as the best cutoff values to predict MS in type 2 diabetes. Conclusions:NC is a helpful tool to detect MS in type 2 diabetes.

Influence of Yuanzhisan Containing Ginseng Radix et Rhizoma or Codonopsis Radix on Memory Disorder / 中国实验方剂学杂志

Objective:To explore the effects of Yuanzhisan （YZS） containing Ginseng Radix et Rhizoma （YZSR） or Codonopsis Radix （YZSD） on memory disorder based on network and experimental pharmacology. Method:The active components and targets of YZS were retrieved from the component database and literature， and the targets of memory disorder from the disease databases. The intersection targets revealed by Veen diagram were subjected to pathway analysis. The common active components of YZSR and YZSD were molecularly docked onto the core targets. Scopolamine hydrobromide was used to establish the memory disorder model， which was employed in the behavioral experiments for evaluating the effect of YZSR and YZSD on memory disorder. Result:There existed 33 active components for Ginseng Radix et Rhizoma and 31 for Codonopsis Radix， with four common active components and 380 common targets. YZSR contained 85 active components and 790 drug targets， and YZSD 81 active components and 781 drug targets. The mapping of 425 memory disorder targets with those of YZSD and YZSD yielded 133 and 130 intersection targets， respectively. The metabolic pathways involved calcium ion signaling pathway， hypoxia-inducible factor-1 （HIF-1） signaling pathway， mitogen-activated protein kinase （MAPK） signaling pathway， etc. As revealed by molecular docking， the binding energy of common active components to the targets was negative， and the binding effect of frutinone A was the best. Behavioral experiment results showed that both YZSR and YZSD alleviated the memory disorder. In the step-down test， the number of errors in the YZSD group was significant lower than that in the model group （<italic>P</italic><0.01）. In Morris water maze test， the movement distance of the YZSD group was remarkably shortened in comparison with that of the model group （<italic>P</italic><0.05）. In the open field test， the movement distances of both the YZSR and YZSD group were shortened in contrast to that in the normal group （<italic>P</italic><0.05）. Conclusion:YZS had a certain effect on memory disorder. There are similarities and differences between YZSR and YZSD in the treatment of memory disorder.

OBJECTIVE：To establish the eva luation criteria for the rationality of tumor nutritional standardized treatment ，and to provide reference for nutritional standardized treatment in tumer patients . METHODS ：Based on domestic and foreign guidelines or expert consensus ，the rationality evaluation standard of tumor nutritional standardized treatmentwas formulated in our hospital （Bozhou Municipal People ’s Hospital ）. 50 nutritional treatment medical records in our hospital from Jan. to Jun. 2019 were evaluated by weighted TOPSIS ；according to the evaluation results ，nutritional intervention was carried out ，and 50 nutritional treatment medical records （group B ）from Aug. to Dec. 2019 were re-evaluated by the same method after intervention. RESULTS ： The established evaluation criteria for the rationality of tumor nutritional standardized treatment in our hospital included 18 indicators，such as malnutrition diagnosis ，description of the nature of malnutrition ，nutrition screening and evaluation ，etc. After analysis ，the rational rate of nutritional treatment was only 18％ in group A （Ci of ideal solution with 9 medical records≥0.6），and 78％ in group B （Ci of ideal solution with59 medical records ≥0.6）. There was statistical significance in the rationality of nutritional treatment before and after nutritional intervention （Ci≥0.6）（P＜0.05）. CONCLUSIONS ：The established rational evaluation method of tumor nutritional standardized treatment is feasible ，and the evaluation results are intuitive and reasonable. Nutrition intervention is helpful to reduce the irrational rate of nutritional treatment.

One-step implementation of Toffoli gate for neutral atoms based on unconventional Rydberg pumping.

Compared with the idea of universal quantum computation, a direct synthesis of a multiqubit logic gate can greatly improve the efficiency of quantum information processing tasks. Here we propose an efficient scheme to implement a three-qubit controlled-not (Toffoli) gate of neutral atoms based on unconventional Rydberg pumping. By adjusting the strengths of Rabi frequencies of driving fields, the Toffoli gate can be achieved within one step, which is also insensitive to the fluctuation of the Rydberg-Rydberg interaction. Considering different atom alignments, we can obtain a high-fidelity Toffoli gate at the same operation time ∼7 µs. In addition, our scheme can be further extended to the four-qubit case without altering the operating time.

Surgical outcomes and survival for T4 gastric cancer extending to the transverse colon.

BACKGROUND: For the treatment of locally advanced (T4) gastric cancer, extended multi-organ resection remains controversial. This study aimed to evaluate the surgical outcomes and survival of patients with T4 gastric cancer extending to the transverse colon. METHODS: A total of 2,652 gastric cancer patients underwent surgery between December 2011 and December 2015. Data from 40 of these patients who underwent curative resection for T4 gastric cancer extending to the transverse colon were obtained. Patient characteristics, related complications, long-term survival, and prognostic factors for T4 gastric cancer were analyzed. RESULTS: Postoperative morbidity occurred in 5 (12.5%) patients. All of the patients were cured with conservative treatment. No procedure-related mortality occurred. The 1-, 3-, and 5-year overall survival (OS) rates were 75.0%, 49.2%, and 36.9%, respectively, with a median survival time of 24 months. Univariate analysis revealed tumor size (P=0.049), advanced T stage (P=0.013), and lymph node metastasis (P=0.006) to be poor prognostic factors of OS. Advanced T stage and lymph node metastasis were identified by multivariate analysis as being independent prognostic factors. Further, it was observed that lymph node metastasis grade was associated with poorer OS. CONCLUSIONS: Patients with T4 gastric cancer extending to the transverse colon might benefit from curative resection with acceptable morbidity and mortality.

Effect of ambrisentan on echocardiographic and Doppler measures from patients in China with pulmonary arterial hypertension.

BACKGROUND: We retrospectively evaluated the echocardiographic data of ambrisentan-treated patients with pulmonary arterial hypertension (PAH) (NCT01808313). METHODS: Change from baseline in right ventricle (RV) systolic function, right heart structure, and pulmonary artery systolic pressure (PASP) prognosis to Weeks 12 and 24 was evaluated by echocardiography. RESULTS: In the overall population, the mean tissue Doppler-derived tricuspid lateral annular systolic velocity (S') increased by 0.6 cm/s at both Weeks 12 (p < 0.001) and 24 (p = 0.004) and tricuspid annular plane systolic excursion increased by 0.13 cm at Week 12 and 0.15 cm at Week 24 (both p < 0.001). A marked decrease in transverse and longitudinal RV and RA diameter at Weeks 12 and 24 was observed. A significant decrease in diastolic eccentricity index at both Weeks 12 (-0.1; p = 0.02) and 24 (-0.1; p = 0.001). The decrease in PASP from baseline was significant at both Weeks 12 (-9.5 mmHg; p<0.001) and 24 (-7.6 mmHg; p<0.001), while a decrease in the estimated right atrium pressure was found to be significant at Week 24 (-0.8mmHg; p = 0.01). CONCLUSION: Significant improvements in a number of RV echocardiographic parameters were observed at Weeks 12 and 24 after ambrisentan treatment in patients with PAH.

Seawater Immersion Aggravates Early Mitochondrial Dysfunction and Increases Neuronal Apoptosis After Traumatic Brain Injury.

Traumatic brain injury (TBI) is a major cause of death and disability in naval warfare. Due to the unique physiochemical properties of seawater, immersion in it exacerbates TBI and induces severe neural damage and complications. However, the characteristics and underlying mechanisms of seawater-immersed TBI remain unclear. Mitochondrial dysfunction is a major cause of TBI-associated brain damage because it leads to oxidative stress, decrease in energy production, and apoptosis. Thus, the present study aimed to further elucidate the current understanding of the pathology of seawater-immersed TBI, particularly the role of mitochondrial dysfunction, using a well-defined rat model of fluid percussion injury and a stretch injury model comprising cultured neurons. The biochemical and pathological markers of brain-related and neuronal injuries were evaluated. Histological analysis suggested that seawater immersion enhanced brain tissue injury and induced a significant increase in apoptosis in rats with TBI. Additionally, lactate dehydrogenase release occurred earlier and at higher levels in stretched neurons at 24 h after seawater immersion, which was consistent with more severe morphological changes and enhanced apoptosis. Furthermore, seawater immersion induced more rapid decreases in mitochondrial membrane potential, adenosine triphosphate (ATP) content, and H+-ATPase activity in the cortices of TBI rats. In addition, the immunochemical results revealed that seawater immersion further attenuated mitochondrial function in neurons exposed to stretch injury. The increases in neuronal damage and apoptosis triggered by seawater immersion were positively correlated with mitochondrial dysfunction in both in vivo and in vitro models. Thus, the present findings strengthen the current understanding of seawater-immersed TBI. Moreover, because seawater immersion aggravates mitochondrial dysfunction and contributes to post-traumatic neuronal cell death, it is important to consider mitochondria as a therapeutic target for seawater-immersed TBI.
