Dechnical development of parastomal hernia repair techniques / 中华胃肠外科杂志

Parastomal hernia is a common complication after abdominal ostomy. Although the European Hernia Society guidelines recommend surgical treatment for parastomal hernia, there is still no "gold standard" procedure. The exploration and practice of parastomal hernia repair surgery has been carried out for many years, from the earlier hernia ring suture and stoma relocation repair, to the reinforcement of meshes (such as the Keyhole repair technique and the Sugarbaker repair technique) and the application of laparoscopic technique, and then to the combination of various methods. The intervention of single-port laparoscopic technique and robot-assisted surgery, the prevention of parastomal hernia, the specialization of treatment, multidisciplinary cooperation, and the improvement of diagnostic methods will all provide more optimal solutions for stoma patients. This article will review and summarize the development process and evaluation of parastomal hernia surgical techniques.

Pharmacological Mechanism of Curcumae Radix in Treatment of Post-stroke Depression： A Review / 中国实验方剂学杂志

Post-stroke depression， a common mental complication after stroke， seriously affects the quality of life and even endangers the life safety of patients. It is difficult to be cured due to the complex and diverse pathogenesis. At present， the widely accepted pathogenesis mechanisms include inflammatory mechanism， neurotransmitter mechanism， and endocrine mechanism. According to the theory of Chinese medicine， Qi stagnation， blood stasis， and phlegm turbidity lead to the occurrence of mental diseases after stroke. Curcumae Radix， as a commonly used Chinese herbal medicine， can activate blood circulation for relieving pain， regulate Qi， and relieve depression. The summary of the medication rules of DENG Tie-tao， ZHANG Xue-wen and other Chinese medical physicians showcases that Curcumae Radix is frequently used in the clinical treatment of depression， stroke， and post-stroke depression. Modern pharmacological studies have demonstrated that Curcumae Radix contains β-sitosterol， curdione， curcumin and other medicinal ingredients. This study reviewed the pharmacological effects of effective components in Curcumae Radix and the pharmacological mechanism in the treatment of post-stroke depression and summarized the processing methods of Curcumae Radix， aiming to clarify the important role and determine the optimal processing method of Curcumae Radix in the treatment of post-stroke depression. The results indicate that Curcumae Radix has the effects of regulating neurotransmitters， inhibiting neuroinflammation， protecting neurons， regulating neuroendocrine and antithrombosis， which can prevent and treat post-stroke depression through multiple components， targets， and pathways. The wine-processed Curcuma longa has the best effect.

Clinical characteristics and risk factors of lower extremity arterial disease in patients with diabetic foot ulcer / 南方医科大学学报

OBJECTIVE@#To investigate the clinical characteristics of lower extremity arterial disease (LEAD) and its risk factors in patients with diabetic foot ulcer (DFU).@*METHODS@#We retrospectively collected the clinical and follow-up data of 650 patients with DFU treated in the Department of Endocrinology and Metabolism of Nanfang Hospital between January, 2017 and December, 2019. We compared the data between patients who had LEAD and those without LEAD and used a multivariate logistic regression model to analyze the risk factors of LEAD in DFU patients.@*RESULTS@#Among the 650 DFU patients, 470 (72.4%) had LEAD. The patients were followed up for a mean of 3.5 months, and the mean healing time of DFU was 2.55 months; healing of DFU occurred in 453 patients and 183 patients received amputation. The patients with LEAD and those without LEAD differed significantly in age, hospitalization costs, diastolic blood pressure (DBP), glycated hemoglobin, blood lipid levels, disease course, ankle brachial index, healing time, smoking history, clinical outcomes, Wagner grade and imaging results (P < 0.05). Multivariate logistic regression analysis identified age (OR=1.070, 95% CI: 1.049-1.091), smoking history (OR= 2.013, 95% CI: 1.268-3.195), and a decreased DBP (OR=0.980, 95% CI: 0.963-0.997) as independent risk factors for LEAD in DFU patients. A prolonged healing time was a prominent clinical feature of DFU complicated by LEAD.@*CONCLUSION@#DFU patients have a high incidence of LEAD, which leads to high rates of disability and mortality and is associated with an advanced age, high smoking rate and longer healing time. A decreased DBP is also a risk factor for LEAD in DFU patients.

Spatial distribution and drug resistance of pulmonary tuberculosis in Nantong in 2017 - 2021 / 公共卫生与预防医学

Objective To analyze the spatial distribution and drug resistance characteristics of pulmonary tuberculosis in Nantong area, and to explore its spatial aggregation characteristics, so as to provide reference for the prevention and treatment of pulmonary tuberculosis in this area in the future. Methods We collected information on tuberculosis cases in Nantong for 2017-2021 years, and compared the characteristics of newly diagnosed / retreated drug-resistant pulmonary tuberculosis in urban and rural areas and North and South regions. At the same time, the situation of drug resistance was discussed, and the differences of drug resistance distribution in different regions were compared. The “hot zone” and “cold zone” of drug-resistant tuberculosis were explored with the help of spatial autocorrelation analysis. Results In the past 2017-2021 years , 485 cases of TB patients were included in this study, including 267 male patients and 218 female patients. The number of elderly patients was more than that of the 55-74 year old group (220/485) 45.36%. The total resistance rate of drug-resistant TB patients was 18.14% (88/485). There were statistically significant various in drug resistance rates among various age, gender, region,occupation and treatment classification. The drug resistance rates of male , 30-59 year old age group and unemployed patients in occupation were the highest. Haichuan and ruzha counties are “drug-resistant development areas”, and “Haichuan and ruzha” are “drug-resistant development areas”. Conclusion The high-risk population of pulmonary tuberculosis in Nantong from 2017 to 2021 is male and elderly. Relevant departments can improve the effect of prevention and control by strengthening the management of high-risk groups and high aggregation areas of drug-resistant pulmonary tuberculosis.

Objective:To investigate the effects of sorafenib on hypoxia inducible factor-1 (HIF-1) and vascular endothelial growth factor (VEGF) levels and recurrence in patients with intrahepatic cholangiocarcinoma with microvascular invasion.Methods:Ninety-two patients with intrahepatic cholangiocarcinoma who received treatment in Yiwu Central Hospital between November 2013 and November 2019 were included in this study. They were randomly assigned to undergo either conventional basic treatment (control group, n = 46) or conventional basic treatment and sorafenib treatment (study group, n = 46). Clinical efficacy, the incidence of adverse reactions and recurrence rate were compared between the two groups. Before and after treatment, HIF-1, alpha fetoprotein (AFP) and VEGF levels were also compared between the two groups. Results:After treatment, total effective rate in the study group was significantly higher than that in the control group [63.04% (29 /46) vs. 28.26% (13/46), χ2 = 11.215, P < 0.05]. After treatment, HIF-1, AFP and VEGF levels in each group were significantly lower than those before treatment (all P > 0.05). After treatment, HIF-1 [(165.23 ± 39.67) pg/mL], AFP [(109.16 ± 67.31) ng/mL] and VEGF [(297.28 ± 42.41) pg/mL] levels in the study group were significantly lower than those in the control group [(205.56 ± 40.23) pg/mL, (235.17 ± 106.41) ng/mL, (365.16 ± 40.91) pg/mL, t = 4.841, 6.788, 7.813, all P < 0.05]. There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Six-month follow-up revealed that the incidence of recurrence in the study group was significantly lower than that in the control group ( χ2 = 4.792, P < 0.05). Conclusion:Sorafenib can reduce the HIF-1, AFP and VEGF levels in patients with intrahepatic cholangiocarcinoma with microvascular invasion, improve the clinical efficacy, decrease the incidence of recurrence, but cannot increase the incidence of adverse reactions.

Objective:To investigate the association of alcohol drinking and the incident risk of type 2 diabetes in men and to provide evidences for early prevention of diabetes. Methods:Rural adult males without diabetes in Deqing County， Zhejiang Province were enrolled. A dynamic prospective cohort study was conducted. Data were collected through questionnaires， physical examination， experimental measurements and a electronic follow-up database. Cox multivariate regression was performed to assess the association of alcohol drinking and the incident risk of type 2 diabetes in men. Results:During the follow-up period （7.15±2.90 years）， 354 men developed diabetes， and the incidence rate was 4.15/1 000 person-years. After adjusting for confounding factors， the incident risk of type 2 diabetes among the men with high alcohol drinking frequency （≥7 times/week） and low single alcohol intake （0.1-19.9 g/occasion） was lower than that among non-alcohol drinkers， and the value of HR （95%CI） was 0.72 （0.56-0.94） and 0.54 （0.30-0.99）， respectively. Consumption of ≥40.0 g alcohol per occasion 3-6 times a week increased the incidence of type 2 diabetes， and consumption of <40.0 g alcohol per occasion over 7 times a week decreased the incidence of type 2 diabetes， with the value of HR （95%CI） of 1.53 （1.02-2.30） and 0.52 （0.28-0.99） respectively. Conclusion:Different alcohol drinking patterns affect the incident risk of type 2 diabetes among rural adult males in Deqing County. Further study on alcohol drinking and diabetes may have ethical and practical significance for the prevention and control of diabetes in rural China.

It is necessary to focus on high-risk patient over 40 years old, more than 24 h of treatment time, VEP extinction, optic nerve swelling poor efficacy. It is worthy of clinical promotion.

Thoracoscopic surgery versus traditional open surgery for infants with congenital diaphragmatic eventration: A retrospective cohort study / 中国胸心血管外科临床杂志

@#Objective    To compare and analyze the treatment effect of thoracoscopic surgery and traditional open surgery on infants with congenital diaphragmatic eventration, and summarize the experience of thoracoscopic surgery in infants with congenital diaphragmatic eventration. Methods    We retrospectively analyzed the clinical data of 105 children with congenital diaphragmatic eventration who received operation in the Department of Cardiothoracic Surgery of Children’s Hospital of Chongqing Medical University from January 2010 to January 2019. The patients were divided into an open group and a thoracoscopic group according to the operation methods. There were 41 patients in the thoracoscopic group, including 30 males and 11 females, with an average of 13.42±11.08 months (range: 1 d to 3 years). There were 64 patients in the open group, including 44 males and 20 females, with an average age of 8.21±9.33 months (range: 15.0 d to 1.6 years). The operation time, intraoperative bleeding volume, postoperative mechanical ventilation time, hospital stay and other operation indexes as well as the mortality, recurrence rate and complication rate of the two groups were observed. Results    The operation indexes such as operation time, intraoperative bleeding volume, postoperative mechanical ventilation time, thoracic drainage time, CCU stay and hospital stay of the thoracoscopic group were better than those in the open group (P<0.05). There was no statistical difference between two groups in postoperative diaphgram muscles descent, postoperative feeding time or patients needing thoracic drainage (P>0.05). The incidence of postoperative complications in the thoracoscopic group (19.51%) was lower than that in the open group (23.44%, P>0.05), and the difference in mortality and recurrence rate between the two groups was not statistically significant (P>0.05). Conclusion    Both thoracoscopic diaphragmatic plication and traditional open surgery can effectively treat congenital diaphragmatic eventration, but compared with traditional open surgery, thoracoscopic diaphragmatic plication has the advantages of shorter operation time, less trauma, more rapid recovery and fewer complications, so it should be the first choice for children with congenital diaphragmatic eventration.

Small-cell carcinoma of the prostate: A report of 2 cases and review of the literature / 中华男科学杂志

Objective@#To investigate the clinicopathological characteristics and improve the clinical treatment of prostatic small-cell carcinoma (PSCC).@*METHODS@#We reported 2 cases of PSCC derived from prostate cancer after treated by androgen blockade and prostate electrotomy and reviewed the relevant literature.@*RESULTS@#Two patients with PSA elevation were diagnosed with prostate cancer by prostatic puncture biopsy and treated by maximum androgen blockade, which reduced their total PSA to the normal level. Later, due to difficult urination, they both underwent prostate electrotomy, followed by chemotherapy or radiotherapy for PSCC confirmed by postoperative pathology. Nevertheless, they died at 8 to 9 months after the discovery of PSCC.@*CONCLUSIONS@#PSCC can derive from prostate cancer after treatment, which may be attributed to the pathological mutation induced by long-term endocrine therapy. PSCC is more malignant than prostate cancer, and its prognosis is poor.

Clinical analysis of 100 adult patients with pure red cell aplasia / 中国实用内科杂志

OBJECTIVE: To evaluate clinical characteristics and treatment response of 100 patients with pure red cell aplasia(PRCA).METHODS: We retrospectively analyzed the clinical data of 100 adult patients with acquired PRCA from October2009 to July 2019, and compared the difference in efficacy between idiopathic and secondary patients.RESULTS: 100 patients were evaluated, including 60 idiopathic patients and 40 secondary patients.The most common reasons for secondary PRCA were large granular lymphocytic leukemia(LGLL)(28 cases,70.0%)and thymoma(6 cases, 15.0%). The remission induced regimens included corticosteroids(CS), cyclosporine A(CsA), or other agents, and the response rate were 66.7%,71.4% and 50%, respectively(P=0.336). Secondary PRCA was less effective than idiopathic PRCA(52.5%,78.3%,P=0.007). PRCA related to large granular lymphocytic leukemia was also less effective compared to idiopathic PRCA(46.4%,79.3%,P=0.003). When treated by CsA, idiopathic PRCA was more effective than secondary PRCA and LGLL related PRCA(P=0.001, P=0.000). Logistic regression analysis showed that lower response rate was related to secondary PRCA and LGLL related PRCA.CONCLUSION: The response rate were similar by different induced regimens. Idiopathic PRCA could acquired better response to CsA than secondary, LGLL related PRCA was less effective to treatment.

Objective To compare the efficacy and safety of surgical thrombectomy with those of catheter-directed thrombolysis (CDT) in treating acute lower limb ischemia (ALLI) . Methods The clinical data of 107 patients with ALLI, who underwent CDT or surgical thrombectomy at authors' hospital during the period from January 2012 to December 2017, were retrospectively analyzed. The incidence of complications, mortality, re-intervention rate and amputation rate within 30 days after operation were calculated. Cooley standard of efficacy score was used to assess the clinical curative effect of patients with grade Ⅱ of American Society of Vascular Surgeons (SVS) and International Society of Cardiovascular Surgery (ISCVS) classification of acute limb ischemia. Results A total of 107 patients with ALLI were enrolled in this study. Among them, 59 patients received CDT therapy and 48 patients received surgical thrombectomy. The technical success rate of both groups was 100％. Within 30 days after operation, the incidence of complications in CDT group and surgical thrombectomy group was 11.9％ and 14.6％ respectively, the mortality was 5.1％ and 6.3％respectively, and the re-intervention rate was 17.0％ and 22.9％ respectively, all the differences were not statistically significant (P>0.05) . The amputation rate of patients with grade Ⅱ of SVS/ISCVS ischemia classification in CDT group was 8.9％, which was higher than 2.3％ in surgical thrombectomy group, but the difference between the two groups was not statistically significant (P>0.05) . In patients with grade Ⅱ of ischemia assessed by the ca uses and Cooley curative effect standard at the time of discharge, the cure percentage of embolism-caused ALLI patients in surgical thrombectomy group was 82.5％, which was remarkably higher than 62.8％ in CDT group (P <0.05) . The cure percentage of thrombosis-caused ALLI patients in CDT group was 92.3％, which was strikingly higher than 25.0％ in surgical thrombectomy group (P <0.05) . The difference in the improvement of ischemia, which was assessed by the duration of ischemia and Cooley therapeutic criteria at the time of discharge, between the two groups was not statistically significant (P>0.05) . Conclusion In treating ALLI, no significant differences in curative effect, incidence of postoperative complications and mortality exist between surgical thrombectomy and CDT. The formulation of therapeutic regimen should be based on ischemia grade of SVS/ISCVS, etiology and coexisting underlying diseases.

Among all the doses, children aged 6 to 11 months, 12 to 23 months and 24 to 59 months were received 13 707, 32 639 and 25 317 doses respectively. The incidence of adverse reactions within 30 min, 3 days and 4-30 days were 0.33% (239 doses), 1.58% (1 133 doses) and 0.34% (244 doses) respectively. Adverse reactions within 3 days were 1 372 doses, with a incidence of 1.91%; among all the cases, 539 doses (0.75%) were grade 1, 677 doses (0.94%) were grade 2 and 156 doses (0.22%) were grade 3, no grade-4 adverse reaction was reported. The common local adverse reactions were redness, swelling and pruritus, with the incidence rates were 0.05% (39 doses), 0.02% (16 doses) and 0.02% (12 doses), respectively, while the most common systemic adverse reaction was pyrexia with an incidence of 1.19% (856 doses), followed by diarrhea and anorexia with the incidence rates were 0.15% (104 doses) and 0.13% (90 doses) respectively.@*Conclusion@#Most adverse actions of EV-A71 vaccines were mild and moderate and majority of them were common adverse actions. No new adverse reactions were found in the study.

Post-marketing observation on safety of inactivated enterovirus A71 vaccine (human diploid cell) / 中华预防医学杂志

Objective@#To evaluate the post-marketing safety of inactivated Enterovirus type 71 (EV-A71) vaccine (human diploid cell) .@*Methods@#A total of 20 191 healthy children aged 6 to 59 months were invited to receive 2 doses of EV-A71 vaccine in Zhejiang Province from September 2016 to December 2017. Child caregivers were followed up on the 4th or 5th day after each EV-A71 vaccination, and the incidence of local, systemic, and other adverse events within 3 days after vaccination was recorded to assess vaccine safety. Describe the differences in adverse events among children with different characteristics.@*Results@#A total of 32 230 doses were observed in this study, of which 20 191 and 12 039 were vaccinated for the first and the second dose, respectively; and the incidence of adverse events within 3 days was 2.045% (413 doses) and 1.611% (194 doses), respectively. After the first and the second dose, the number of systemic adverse events was the highest, 371 and 175 cases, respectively, with an incidence of 1.837% and 1.454%, respectively; the number of local adverse events was the lowest, 14 and 2 doses, respectively, with an incidence of 0.069% and 0.017%. Local adverse events occurred after vaccination were generally mild, and only 2 patients had level of 3; among the systemic adverse events, 39 patients had a fever level of 3 or higher, accounting for 8.2% of the total fever. Most of the symptoms in the local adverse events did not require treatment, only 3 cases of vaccination site rash and 2 cases of pruritus were self-purchased drugs or outpatient treatment; except for 5 cases of fever, the other symptoms were not hospitalized in the case of systemic adverse events.@*Conclusion@#The incidence of adverse events within 3 days after vaccination with EV-A71 vaccine was low in children, mainly systemic adverse events, and the prognosis was good.
