Objective To elucidate the causal relationships between colorectal cancer (CRC) and prevalent psychiatric disorders through a two-sample Mendelian randomization approach. Methods Utilizing publicly available genome-wide association study data, we explored the connections between CRC and various psychiatric disorders, including depression, anxiety, bipolar disorder, and schizophrenia. We applied three statistical analyses: inverse variance weighting, MR-Egger, and median weighting. Sensitivity analyses were conducted to ensure the reliability and validity of the results. Results Inverse variance weighting analysis showed no significant links between CRC and depression (P=0.090), anxiety (P=0.099), or schizophrenia (P=0.899). Conversely, a significant inverse relationship was found with bipolar disorder (P=0.010). Conclusion No causal connection exists between CRC and the psychiatric conditions of depression, anxiety, or schizophrenia. However, CRC may have a causal association with a reduced risk of bipolar disorder, further supporting the existence of the gut-brain axis.

Background::A phase II trial on recombinant human tenecteplase tissue-type plasminogen activator (rhTNK-tPA) has previously shown its preliminary efficacy in ST elevation myocardial infarction (STEMI) patients. This study was designed as a pivotal postmarketing trial to compare its efficacy and safety with rrecombinant human tissue-type plasminogen activator alteplase (rt-PA) in Chinese patients with STEMI.Methods::In this multicenter, randomized, open-label, non-inferiority trial, patients with acute STEMI were randomly assigned (1:1) to receive an intravenous bolus of 16 mg rhTNK-tPA or an intravenous bolus of 8 mg rt-PA followed by an infusion of 42 mg in 90 min. The primary endpoint was recanalization defined by thrombolysis in myocardial infarction (TIMI) flow grade 2 or 3. The secondary endpoint was clinically justified recanalization. Other endpoints included 30-day major adverse cardiovascular and cerebrovascular events (MACCEs) and safety endpoints.Results::From July 2016 to September 2019, 767 eligible patients were randomly assigned to receive rhTNK-tPA ( n = 384) or rt-PA ( n = 383). Among them, 369 patients had coronary angiography data on TIMI flow, and 711 patients had data on clinically justified recanalization. Both used a –15% difference as the non-inferiority efficacy margin. In comparison to rt-PA, both the proportion of patients with TIMI grade 2 or 3 flow (78.3% [148/189] vs. 81.7% [147/180]; differences: –3.4%; 95% confidence interval [CI]: –11.5%, 4.8%) and clinically justified recanalization (85.4% [305/357] vs. 85.9% [304/354]; difference: –0.5%; 95% CI: –5.6%, 4.7%) in the rhTNK-tPA group were non-inferior. The occurrence of 30-day MACCEs (10.2% [39/384] vs. 11.0% [42/383]; hazard ratio: 0.96; 95% CI: 0.61, 1.50) did not differ significantly between groups. No safety outcomes significantly differed between groups. Conclusion::rhTNK-tPA was non-inferior to rt-PA in the effect of improving recanalization of the infarct-related artery, a validated surrogate of clinical outcomes, among Chinese patients with acute STEMI.Trial registration::www.ClinicalTrials.gov (No. NCT02835534).

Aim To investigate the relationship between fibrinogen(FIB)and the progression of coronary plaque stenosis rate in patients with type 2 diabetes mellitus(T2DM).Methods Hospitalized T2DM patients who underwent two or more coronary CT angiography(CCTA)examinations in the First Affiliated Hospital of Xi'an Jiaotong U-niversity from January 2015 to December 2020 were included.The subjects were divided into high FIB and low FIB groups according to the median of FIB.The differences in the progression of coronary plaque stenosis rate and other clini-cal characteristics were compared between the two groups,and the relationship between FIB level and the progression of coronary plaque stenosis rate was analyzed by Spearman's correlation analysis and Logistic regression.Results A total of 145 patients were included,73 in the high FIB group and 72 in the low FIB group at baseline,with a median follow-up time of 25(18,40)months between CCTA.The age,proportion of women,and the progression of coronary plaque ste-nosis rate were higher in the high FIB group than those in the low FIB group,and the differences were statistically signifi-cant(P＜0.05).FIB level was positively correlated with the change in coronary plaque stenosis rate(r2=0.308,P＜0.001).Multivariate Logistic regression analysis showed that FIB level was a risk factor for the progression of coronary plaque stenosis rate in patients with T2DM(OR=5.25,95％CI:1.97～14.02,P＜0.001),after adjusting for age,sex and other clinical risk factors.Conclusion High baseline FIB level is an independent risk factor for the progression of coronary plaque stenosis rate in patients with T2DM,and monitoring FIB level is beneficial to cardiovascular risk stratifica-tion in patients with T2DM.

Multiple myeloma is a kind of hematological malignancy commonly seen in the elderly.Its main feature is that abnormal proliferation of bone marrow plasma cells replace normal bone marrow,which changes the water fat ratio of vertebral bone marrow,leading to bone destruction and bone marrow infiltration.At present,dual energy CT virtual non calcium and modified Dixon Quant can detect the changes of bone marrow and conduct qualitative and quantitative analysis of bone lesions,which can assist in the diagnosis of multiple myeloma,prompt treatment response and judge the prognosis of patients.This paper reviews the application progress of the above two quantitative techniques in multiple myeloma,in order to provide imaging reference for the diagnosis and treatment of multiple myeloma.

Our team created the pathogenesis theory of cancer toxin in traditional Chinese medicine on the basis of inheriting the academic thought of "cancer toxins" of ZHOU Zhongying, a Chinese medical master.The pathogenesis theory of cancer toxin suggests that cancer toxins is the key factor leading to the occurrence and development of malignant tumors, the basic pathogenesis of malignant tumor is accumulation of evil and toxins, deficiency of vital qi. This paper proposes that the main pathological factors of carcinoma of prostate are deficiency, dampness, heat, stasis and toxins. The core pathogenesis was spleen and kidney deficiency, dampness-heat stasis toxin accumulation in essence chamber. The disease is located in the essence chamber, closely related to kidney and bladder, and involves liver and spleen. Clinical treatment is based on anti-cancer and detoxification, strengthening vital qi to eliminate pathogenic factor as the basic treatment principles, treatment with anti-cancer detoxification as the core, tonifying the spleen and kidney as the fundamental, clearing heat and removing dampness, removing blood stasis and dispersing is key, accompanied by dispersing liver and regulating qi, the whole syndrome differentiation, to maintain a stable period of time. Strengthening vital qi does not leave evil, eliminating evil does not harm vital qi. Guided by the pathogenesis theory of cancer toxin, this paper expounds the treatment of carcinoma of prostate based on syndrome differentiation and highlights the key role of the pathogenesis theory of cancer toxin in the treatment of this disease, providing reference for the differentiation and treatment of carcinoma of prostate.

As a commonly used traditional Chinese medicine,Alpinia oxyphylla is widely used as both medicine and edible resources.A.oxyphylla has the effects of warming the kidney,consolidating essence,contracting urine,warming the spleen,stopping diarrhea and absorbing saliva,which mainly treated diseases caused by kidney deficiency and spleen cold.A.oxyphylla is rich in chemical components,mainly including 194 volatile oil,121 terpenoids(including 111 sesquiterpenoids),19 diphenylheptanes,ten flavonoids,ten bases and nucleosides,four steroids,eight glycosides and 13 organic acids.It has a wide range of pharmacological effects such as anti-AD/PD,anti-tumor,anti-inflammatory,antioxidant,etc.This article reviews the chemical components and pharmacological effects of A.oxyphylla,in order to provide reference for its further development and rational application.

This paper summarizes the exploration process and academic significance of the academic thought of Zhou Zhongying,a master of traditional Chinese medicine,who took the creation of a new system of TCM pathogenesis theory as the core,and interprets its theoretical connotation.As a pioneer in the construction of higher education textbooks for traditional Chinese medicine,Professor Zhou Zhongying created the outline of TCM internal medicine viscera differentiation,persisted in carrying out innovative research on patho-genesis theory,achieved fruitful academic results,and enriched and developed the academic system of TCM theory.In the clinical di-agnosis and treatment of exogenous febrile diseases and acute and difficult internal injuries,he systematically created new pathogenesis theories such as stasis-heat theory and cancer toxicity theory.Based on this,the legislation of medication can improve the clinical effi-cacy,and it is realized that identifying the pathogenesis is the key link in syndrome differentiation and treatment.In his later years,Professor Zhou Zhongying,guided by the holistic view,proposed the"thirteen pathogenesis"and constructed a new system of TCM pathogenesis differentiation,highlighting the guiding value of complex pathogenesis and the causal chain of pathogenesis elements to complex clinical diseases and syndromes,forming a theory with the idea of"examining syndromes and seeking pathogenesis,activating syndrome differentiation"as its soul.This theory breaks through the rigid thinking of syndrome differentiation and treatment based on a single pathogenesis or fixed syndrome type,reconstructs the theoretical framework of TCM with the idea of holistic view,and is a major academic innovation in modern TCM.

Objective     To investigate the effect and prognosis of patients with ventricular septal rupture after myocardial infarction treated by surgical repair combining an occluder and a patch. Methods     Clinical data of 42 patients with myocardial infarction complicated with ventricular septal rupture admitted to the First Affiliated Hospital of Zhengzhou University from January 2010 to September 2021 were retrospectively analyzed. According to the surgical methods, 27 patients were divided into a traditional group, including 17 males and 10 females, with an average age of 62.81±6.81 years, who were repaired by patch only, and 15 patients were divided into a modified group, including 11 males and 4 females, with an average age of 64.27±9.24 years, who were repaired by surgery combining an occluder and a patch. Perioperative and follow-up data of the two groups were compared and analyzed. Results     There were statistical differences between the two groups in preoperative Killip grading, rate of intra-aortic balloon pump use, interval from myocardial infarction to operation, and the number of culprit artery (P<0.05). There was no statistical difference in other preoperative data, the cardiopulmonary bypass time, aortic cross-clamping time, postoperative hospital stay or in-hospital death rate between the two groups (P>0.05). No residual shunt occurred in the modified group, and the difference was statistically significant compared with the traditional group (P=0.038). There was no statistical difference in other complications between the two groups (P>0.05). The median follow-up time was 4 years. Two patients in the traditional group and one in the modified group died during follow-up. The follow-up cardiac function grading of patients in the modified group was statistically different from that in the traditional group (P=0.023). Conclusion     The perioperative  mortality of ventricular septal rupture after myocardial infarction is high, but the long-term effect is satisfactory. Surgical repair combining an occluder and a patch is a safe and effective treatment for ventricular septal rupture, which can effectively reduce postoperative residual shunt.

Consecutively hospitalized patients with confirmed coronavirus disease 2019 (COVID-19) in Wuhan, China were retrospectively enrolled from January 2020 to March 2020 to investigate the association between the use of renin-angiotensin system inhibitor (RAS-I) and the outcome of this disease. Associations between the use of RAS-I (angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB)), ACEI, and ARB and in-hospital mortality were analyzed using multivariate Cox proportional hazards regression models in overall and subgroup of hypertension status. A total of 2771 patients with COVID-19 were included, with moderate and severe cases accounting for 45.0% and 36.5%, respectively. A total of 195 (7.0%) patients died. RAS-I (hazard ratio (HR)= 0.499, 95% confidence interval (CI) 0.325-0.767) and ARB (HR = 0.410, 95% CI 0.240-0.700) use was associated with a reduced risk of all-cause mortality among patients with COVID-19. For patients with hypertension, RAS-I and ARB applications were also associated with a reduced risk of mortality with HR of 0.352 (95% CI 0.162-0.764) and 0.279 (95% CI 0.115-0.677), respectively. RAS-I exhibited protective effects on the survival outcome of COVID-19. ARB use was associated with a reduced risk of all-cause mortality among patients with COVID-19.

Objective:To investigate the clinical efficacy of pancreaticoduodenectomy with TRIANGLE operation in the treatment of pancreatic head cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 51 patients with pancreatic head cancer who were admitted to the Sichuan Provincial People′s Hospital, Affiliated Hospital of School of Medicine of University of Electronic Science and Technology of China from January 2017 to July 2018 were collected. There were 33 males and 18 females, aged from 42 to 74 years, with a median age of 56 years. Of the 51 patients, 24 cases undergoing standard pancreaticoduodenectomy, in which No.12, 13 and 17 lymph nodes were dissected, combined with transcatheter arterial infusion chemo-therapy (TAI) were allocated into the standard group, and 27 cases undergoing pancreaticoduo-denectomy with TRIANGLE operation, in which No.7, 8, 9, 12, 13, 16, 17 lymph nodes were dissected, combined with TAI were allocated into the TRIANGLE group, respectively. Observation indicators: (1) intraoperative conditions of the two groups; (2) postoperative conditions of the two groups; (3) follow-up and survival. Follow-up was conducted using outpatient examination and telephone interview once three months to detect tumor recurrence and metastasis and survival of patients up to July 2021 or the death of patient. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the chi-square test or the Fisher exact probability. Comparison of ordinal data was analyzed using the rank sum test. Kaplan‐Meier method was used to calculate the survival rate and median survival time and draw survival curve. Log‐Rank test was used for survival analysis. Results:(1) Comparison of intraoperative conditions between the two groups. The operation time, volume of intraoperative blood loss, cases with intraoperative blood transfusion were (501±61)minutes, (563±278)mL, 4 in the standard group, versus (556±46)minutes, (489±234)mL, 6 in the TRIANGLE group, respectively. There was a significant difference in the operation time between the two groups ( t=3.62, P<0.05) but there was no significant difference in the volume of intraoperative blood loss or cases with intraoperative blood transfusion between the two groups ( t=1.03, χ2=0.25, P>0.05). (2) Comparison of postoperative conditions between the two groups. Of the 51 patients, 30 had 50 times of postoperative complications, including 18 times of grade Ⅰ complications of Clavien-Dindo classification, 29 times of grade Ⅱ complications of Clavien-Dindo classification, 2 times of grade Ⅲa complications of Clavien-Dindo classification, 1 time of grade Ⅲb complications of Clavien-Dindo classification, respectively. Cases with postoperative complications, cases with delayed gastric emptying, cases without or with pancreatic fistula as class A or class B, cases with biliary fistula, cases with bleeding, cases with diarrhea were 15, 4, 13, 7, 4, 4, 2, 2 in the standard group, versus 15, 6, 14, 10, 3, 4, 1, 3 in the TRIANGLE group, respectively. There was no significant difference in cases with postoperative complications, cases with delayed gastric emptying, cases with pancreatic fistula between the two groups ( χ2=0.16, 0.02, Z=-0.04, P>0.05) and there was no significant difference in cases with biliary fistula, cases with bleeding, cases with diarrhea between the two groups ( P>0.05). Cases with complications as Clavien-Dindo grade Ⅰ, grade Ⅱ, grade Ⅲ were 10, 11, 2 in the standard group, versus 8, 18, 1 in the TRIANGLE group, showing no significant difference between the two groups ( Z=-0.67, P>0.05). The duration of postoperative hospital stay was (23±8)days in both of the standard group and the TRIANGLE group, showing no significant difference between the two groups ( t=0.31, P>0.05). (3) Follow-up and survival. All the 51 patients were followed-up for 6 to 54 months, with a median follow-up time of 17 months. The postoperative 1-year overall survival rate was 75.0% and 81.5% in the standard group and the TRIANGLE group, respectively. The postoperative 3-year overall survival rate was 12.5% and 22.2% in the standard group and the TRIANGLE group, respectively. The median postoperative survival time was 15.00 months (95% confidence interval as 12.63 to 17.37 months) and 21.00 months (95% confidence interval as 15.91 to 19.62 months) in the standard group and the TRIANGLE group, respectively. There was a significant difference in survival of patients between the two groups ( χ2=4.30, P<0.05). Cases with tumor recurrence during post-operative 1 year and 3 year were 9 and 20 in the standard group, versus 6 and 15 in the TRIANGLE group, respectively. There was no significant difference in cases with tumor recurrence during postoperative 1 year between the two groups ( P>0.05) and there was a significant difference in cases with tumor recurrence during postoperative 3 year between the two groups ( P<0.05). Conclusion:Compared with standard pancreaticoduodenectomy, pancreaticoduodenectomy with TRIANGLE operation can prolong the median survival time of patients with pancreatic head cancer without increasing surgical related complications.
