Objective:To observe the clinical effect of wheat grain-sized cone moxibustion combined with fire needle therapy in the treatment of dorsal wrist ganglion (DWG). Methods:A total of 63 patients with DWG were randomized into a treatment group (n=32) and a control group (n=31). Cases in the control group were treated with fire needle therapy. Based on the therapy given to the control group, cases in the treatment group were additionally given wheat grain-sized cone moxibustion therapy. Then the therapeutic efficacies and recurrence rate were evaluated. Results:After treatment, the overall effective rate was 93.8% in the treatment group, versus 77.4% in the control group, and the between-group comparison showed a statistical significance (P<0.05); 6 months after the treatment, the recurrence rate in the treatment group was obviously lower than that in the control group (P<0.05). Conclusion:The long-term and short-term effects of wheat grain-sized cone moxibustion combined with fire needle therapy in the treatment of DWG are better than those of fire needle therapy alone, and therefore, worth popularizing.

Objective: To evaluate the impacts of the prognostic factors of T2N0M0 upper tract urothelial carcinoma (UTUC) for Chinese patients.Methods: A retrospective study was conducted including 235 patients who were diagnosed with T2N0M0 UTUC in our hospital and received radical nephroureterectomy (RNU) or partial ureterectomy during January 2000 and December 2013.The 3 and 5-year can-cer-specific survival rates and bladder recurrence-free survival rates of all the patients were valued using Kaplan-Meier method, and the survival curves with statistical significance between the two were compared using the Log-rank test.Variables with significant differences in the univariate analysis were subjected to the multivariate analysis by Cox regression model.Results: A total of 235 patients were included in this study, including 95 (40.4%) male patients and 140 (59.6%) female patients.The mean age was 66.73±10.49 years.The median follow-up time was 53 (rang: 3-142) months, and during the follow-up, 74 (31.5%) patients died of UTUC after a median of 35 months,and 96 (40.9%) patients developed intravesical recurrence after a median of 19.5 months.The 3 and 5-year cancer-specific survival rates of all the patients were 89.1% and 85.9%, respectively;the bladder recurrence-free survival rates were 85.5% and 80.2%, respectively.The independent prognostic factors of cancer-specific mortality were tumor age elder than 55 years (HR=3.138, 95%CI: 1.348-7.306, P=0.008) and diameter larger than 5 cm (HR=3.320, 95%CI: 1.882-5.857, P<0.001).The independent prognostic factors of bladder recurrence-free survival were ureter tumor (HR=1.757, 95%CI: 1.159-2.664, P=0.008) and lower tumor grade (HR=1.760, 95% CI: 1.151-2.692, P=0.009).Conclusion: T2N0M0 UTUC has a better cancer-specific survival.The intravesical recurrence was equivalent to non-muscle invasive UTUC but earlier.The tumor diameter larger than 5 cm and the patient age elder than 55 years were independently associated with cancer-specific mortality;the primary tumor located in ureter and lower tumor grade were more likely to develop intravesical recurrence.

Objective To explore the inhibitory effect of saikosonin a(SSa)on pentylenetetrazol-induced acute epilepsy seizures in a mouse model of depression and explore the mechanism mediating this effect.Methods Male C57BL/6J mouse models of depression was established by oral administration of corticosterone via drinking water for 3 weeks,and acute epileptic seizures were induced by intraperitoneal injection of a single dose of pentylenetetrazole.The effect of intraperitoneal injection of SSa prior to the treatment on depressive symptoms and epileptic seizures were assessed using behavioral tests,epileptic seizure grading and hippocampal morphology observation.ELISA was used to detect blood corticosterone levels of the mice,and RT-qPCR was performed to detect the pro-and anti-inflammatory factors.Microglia activation in the mice was observed using immunofluorescence staining.Results The mouse model of corticosterone-induced depression showed body weight loss and obvious depressive behaviors with significantly increased serum corticosterone level(all P<0.05).Compared with those with pentylenetetrazole-induced epilepsy alone,the epileptic mice with comorbid depression showed significantly shorter latency of epileptic seizures,increased number,grade and duration of of seizures,reduced Nissl bodies in hippocampal CA1 and CA3 neurons,increased number of Iba1-positive cells,and significantly enhanced hippocampal expressions of IL-1β,IL-10,TNF-α and IFN-γ.Pretreatment of the epileptic mice with SSa significantly prolonged the latency of epileptic seizures,reduced the number,duration,and severity of seizures,increased the number of Nissl bodies,decreased the number of Iba1-positive cells,and reduced the expression levels of IL-1β,IL-10,TNF-α,and IFN-γ in the hippocampus(P<0.05).Conclusion Depressive state aggravates epileptic seizures,increases microglia activation,and elevates inflammation levels.SSA treatment can alleviate acute epileptic seizures in mouse models of depression possibly by suppressing microglia activation-mediated inflammation.

Objective To explore the clinical feasibility of robot-assisted laparoscopic radical cystectomy (RARC) with total intracorporeal othotopic ileal neobladder (TIOIN).Methods A consecutive series of 4 patients (2 male,2 female),who underwent RARC with TIOIN by a single surgeon,were included in the retrospective study,between March 2017 and June 2017.Their age ranged from 59 to 71 years,which the mean age was (65.7 ± 4.9) years.Preoperative urinary CT scan,cystoscopic examination and transurethral resection of bladder tumor were performed for diagnosis.Among these,2 patients underwent side-to-side bowel anastomosis using a linear stapler,while hand-sewn anastomosis was performed in the other 2 patients.The detubularized bowel segment was arranged in a U shape,and then the two medial borders were closed to create the posterior wall of the neobladder,which completed a partial U shape and anastomosed with the end of urethra.After placing the single J stents into the ureter,the uretero-neobladder was anastomosed.To close the urine reservoir,each border of the U-shaped segment was folded again and sutured to form a sealed pouch.Results All operations were performed successfully.The average operation time for RARC was 93.2 min (ranging 79-117 min).The average operation time for urinary diversion was 214.2 min (ranging 163-251 min).The mean estimated blood loss was 304.5 ml (ranging 200-400 ml).The mean hospital stay was 20.5 d (ranging 13-32 day).The number of dissected lymph node ranged from 11 to 16 (mean 3.7 ± 2.6).All the surgical margins were negative.The time for postoperative out-of-bed activity and bowel function recovery was 2-3 days and 3-4 days,respectively.The single-J stents were removed 1 months after operation,generally.No urine leakage was noticed after removing the drainage tube and catheter.The lymph leakage was observed in one case,which was resolved 15 days post-operatively after given nutrient therapy.The performance of urinary continence was satisfactory,except one patient complained about the nocturnal incontinence.After the regular pelvic exercise,the symptom improved two months after the operation.Hydronephrosis and intestinal leakage were not observed.Conclusions Our initial experience showed that RARC with TIOIN is feasible and alterative for experienced surgeon.

Objective:To study the clinical characteristics and classification of gastric neuroendocrine neoplasm(NEN) and prognostic factors of mixed adenoneuroendocrine carcinoma (MANEC) and gastric neuroendocrine carcinoma(NEC).Methods:A total of 148 gastric NENs were divided into type Ⅰ, type Ⅱ and type Ⅲ based on the classification of European Neuroendocrine Tumor Society (ENETS). Kaplan-Meier test and Cox regression model were used in univariate and multivariate survival analysis in 108 cases with pathological G3 gastric NEN.Results:In this study, the percentages of type Ⅰ, type Ⅱ and type Ⅲ were 25.0%(37), 3.4%(5) and 71.6%(106) respectively. Among type Ⅰ patients, 28(75.7%) lesions were located in gastric fundus or body, 29(78.4%) had bumps. Lymph node involvement was found in 4 (10.8%) patients. Twenty-six (70.3%) patients received endoscopic treatment and 11 (29.7%) with surgery. All 5 type Ⅱ patients presented lesions in gastric fundus or body, including 4 with ulcers, who were all treated by endoscope. Three type Ⅱ patients had gastrinoma, and 2 combined with multiple endocrine neoplasmⅠ. In type Ⅲ patients, 56(52.8%) showed ulcerative lesions. The majority of patients (102, 96.2%) had a single lesion, 94(88.7%) with lymph node or other organ metastasis. In this study, no deaths were reported in gastric NEN with a pathological grade of G1 or G2. The mortality rate was 38.9%(42/108) in patients with G3 NEN. Survival analysis suggested that age, metastasis of tumor were associated with poor prognosis ( P=0.041, 0.025). Conclusions:Patients with gastric NEN have heterogenous clinical presentations according to gender, age, endoscopic features, infiltration and metastasis, and pathological grade. Aging and metastasis are negative prognostic factors of G3 gastric NEN.

Objective:To study the efficacy and safety of EndoClot polysaccharide hemostatic system (EndoClot PHS) for heparinized arterial hemorrhage of upper digestive tract (Forrest Ⅰa) in animal model.Methods:Twelve experimental pigs were randomly divided into the test group ( n=6) and the control group ( n=6) by simple random grouping method. Gastric arterial hemorrhage models were established. Endoclot PHS and Hemospray were used to spray on the wound to stop bleeding in the test group and the control group respectively. The time of effective hemostasis, the amount of hemostatic particles used, and the blockage of the powder feeding tube and its replacement were compared between the two groups. The survival and complications of experimental pigs were observed after the operation. In 10 days after the operation, the experimental pigs were euthanized for pathological dissection. Results:Spurting or pulsatile bleeding was achieved in all experimental pigs. There were significant differences in the time of effective hemostasis (8.75±0.84 min VS 9.83±0.62 min, t=-2.53, P=0.030) and the amount of hemostatic particles used to achieve effective hemostasis (6.71±0.39 g VS 14.10±1.62 g, t=-10.86, P<0.001) between the test group and the control group. There was no significant difference in the occurence of clogging or the replacement of powder feeding pipes between the two groups (0.64±0.02 times VS 0.67±0.04 times, t=-1.64, P=0.131). In addition, the gas source of the test group was stable, and the visual field under the endoscope was clear. Neither the test group nor the control group had gastric lesions, perforation, or embolism. The blood glucose, blood routine, and liver and kidney functions were normal, and no thrombosis or embolism of the main organs occurred in either group. Conclusion:EndoClot PHS is safe and effective for heparinized upper gastrointestinal arterial hemorrhage (Forrest Ⅰa) in animal models.

With the development of society, the dietary pattern of Chinese residents gradually tends to be Westernized, and the disease spectrum has also been progressively changed into chronic non-communicable diseases like ischemic heart disease and stroke. Diet has been recognized as a common and modifiable factor for many chronic diseases. In this paper, the researches on dietary patterns and common chronic non-communicable diseases in recent years were summarized by searching the literature in Chinese and English databases in the past five years (2015-2020). This research integrated the outcome indicators, possible mechanisms, and research conclusions of dietary patterns and cardiovascular system, metabolic diseases, digestive system, locomotor system, and mental system in the past five years from the perspective of the human system. Dietary patterns characterized by red meat and processed meats, fast foods, sugary beverages were identified as risk factors for most diseases. In contrast, nutritional patterns characterized by vegetables, fruits, whole grains, fish were protective factors for most conditions. Meanwhile, it also put forward some problems that should be paid attention to in studying dietary patterns to provide a scientific basis for the follow-up research and the prevention and intervention of diseases.

Suboptimal diet is one of the most important controllable risk factors for non-communicable diseases. However, randomized controlled trials make it difficult to quantify the causal association between specific dietary factors and health outcomes. In recent years, the rapid development of causal inference has provided a robust theoretical and methodological tool for making full use of observational research data and producing high-quality nutritional epidemiologic research evidence. The causal graph model visualizes the complex causal relationship system by integrating a large amount of prior knowledge and provides a basic framework for identifying confounding and determining causal effect estimation strategies. Different analysis strategies such as adjusting confounders, instrumental variables, or mediation analysis can be created based on other causal graphs. This paper introduces the idea of the causal graph model and the characteristics of various analysis strategies and their application in nutritional epidemiology research, aiming to promote the application of the causal graph model in nutrition and provide references and suggestions for the follow-up research.

Objective:To explore the efficacy of long intramedullary nails versus short intramedullary nails in the treatment of AO/OTA 31-A3 intertrochanteric fractures.Methods:A retrospective analysis was conducted on 60 patients with AO/OTA 31-A3 intertrochanteric femur fractures treated between March 2019 and August 2022. The patients were randomly divided into two groups (the long nail group and the short nail group). Thirty-four patients were treated with long intramedullary nails, including 16 males and 18 females, aged 68.41±17.84 years old (range 31-96 years). Twenty-six patients were treated with short intramedullary nails, including 13 males and 13 females, aged 72.23±13.97 years old (range 31-90 years). The causes of injury, fracture classification (AO/OTA classification), intraoperative blood loss, operation time, fracture healing time, imaging indexes (fracture reduction quality, postoperative neck trunk angle, and medial support), Harris score of the hip joint at the last follow-up, one-year mortality rates and complications were compared between the two groups.Results:The follow-up time was 24.26±6.67 months in the long nail group and 24.31±5.60 months in the short nail group, and the general information of the two groups were comparable. Between the long nail and short nail group, the intraoperative blood loss was 281.47±235.28 ml vs. 121.92±84.14 ml and the operation time was 110.44±24.63 min vs. 81.15±28.54 min with significant differences ( P<0.05). While the length of hospital stay was 12.35±4.81 d vs. 10.89±4.30 d, the good rate of fracture reduction was 55.9% vs. 61.53%, the fracture healing time was 120.44±16.43 d vs. 128.07±18.33 d, the presence rate of medial support was 67.6% vs. 79.4%, and the excellent rate of Harris score was 65.4% vs. 65.4% with no significant difference between the two groups ( P>0.05). One-year mortality rates was 5.3% vs. 7.1% and complications was 11.7% vs. 15.4% with no significant difference between the two groups ( P>0.05). Conclusion:Both long intramedullary nails and short intramedullary nails are effective in the treatment of AO/OTA 31-A3 intertrochanteric femur fractures. However, surgical time and intraoperative blood loss was less in the short nail group.
