ObjectiveTo evaluate the efficacy of Shexiang Baoxinwan in treating stable angina pectoris with Qi stagnation and blood stasis syndrome in patients with coronary artery disease （CAD） complicated with anxiety and depression and explore its underlying mechanisms. MethodsThis study employed a randomized， double-blind， and placebo-controlled clinical trial design. Patients admitted to the hospital were randomly assigned to the observation group and the control group， with 52 patients in each group. Patients in the observation and control groups received Shexiang Baoxinwan and placebo， respectively， both in combination with conventional Western medication. The dose was 45.0 mg， three times daily， for a total duration of eight weeks. The primary outcome was the Seattle Angina Questionnaire （SAQ） scores before and after treatment. Secondary outcomes included changes in traditional Chinese medicine （TCM） syndrome score， the patient health questionnaire-9 （PHQ-9）， generalized anxiety disorder-7 （GAD-7）， inflammatory markers ［interleukin-18 （IL-18）， interleukin-10 （IL-10）， tumor necrosis factor-alpha （TNF-α）， CD40， etc.］， monoamine neurotransmitters ［e.g.， dopamine （DA）］， vascular endothelial function markers ［e.g.， endothelin-1（ET-1）］， adipokines， and ischemia-modified albumin （IMA）. Adverse reactions were also recorded. ResultsA total of 92 patients completed the study， with 44 in the observation group and 48 in the control group. Compared with baseline， both groups showed significant decreases in PHQ-9， GAD-7， and TCM syndrome scores following treatment （P<0.05）， along with a significant increase in SAQ scores （P<0.05）. In the observation group， DA levels were significantly increased （P<0.05）， while levels of IL-18， TNF-α， CD40， ET-1， and IMA were decreased （P<0.05）. In contrast， the control group exhibited significantly increased CD40 levels （P<0.05）. Compared with the control group after treatment， the observation group showed significant improvements in the SAQ dimensions of physical limitation， angina stability， treatment satisfaction， and disease perception， as well as in TCM syndrome score， PHQ-9 score， IL-18， CD40， ET-1， and IMA （P<0.05）. No adverse reactions were observed in either group during treatment. ConclusionShexiang Baoxinwan can improve anxiety and depression， alleviate angina symptoms， and reduce TCM symptoms of Qi stagnation and blood stasis in CAD patients. The mechanism may involve anti-inflammation， improvement of vascular endothelial function， reduction of IMA， and increase of monoamine neurotransmitter levels.

Mitochondria are the main site of energy metabolism in cardiomyocytes， and at the same time mediate apoptosis and immune response， so mitochondrial dysfunction is closely related to the development of heart failure. Combined with the pathogenesis of mitochondrial dysfunction and heart failure， it is proposed that the mitochondrial function is similar to "sweat pore - collaterals - zang and fu organs"， according to which the treatment of heart failure is based on the theory of "sweat pore - collaterals - zang and fu organs". It is believed that the core mechanism of heart failure is qi deficiency， and qi deficiency leads to the weakness of the sweat pore opening and closing， or even the sweat pore closure， then resulting in qi deficiency and blood stasis， collaterals stagnation fail to flourish， and qi， blood， and body fluids can not infiltrate and nourish zang-fu organs， so that the heart fail to be nourished， and the disease will develop. The treatment should be based on the method of boosting qi and opening sweat pore， using acridity to unblock the collaterals， and invigorating blood and draining water， with medicinal of boosting qi， invigorating blood， and draining water as treatment.

OBJECTIVE To summarize the strategies and potential drugs that can improve the oxygen affinity of red blood cells in the hypobaric and hypoxic environment in the current research. METHODS The retrieved literatures were screened, extracted and summarized by referring to the literature on the relationship between hypobaric hypoxic environment and erythrocyte oxygen affinity in CNKI database, Web of Science database and Pubmed database. RESULTS Under the hypobaric and hypoxic environment, the body’s oxygen uptake capacity and oxygen utilization efficiency decreased, resulting in the body being in a state of hypoxia. Improving the oxygen affinity of red blood cells could help the body adapt to and get used to the hypobaric and hypoxic environment, and many improvement methods had been applied in other diseases. CONCLUSION Improving the oxygen utilization rate of red blood cells by increasing the oxygen affinity of erythrocytes under hypobaric and hypoxia environment is the starting point and focus of the current research on preventing the damage of high altitude hypobaric and hypoxic environment to the human body.

The plateau is a special environment with low pressure,low oxygen,low temperature,and high ultraviolet radiation.The exercise performance of people on the plateau is generally reduced,which seriously affects the life and health of people living in the plateau and entering the plateau.In recent years,the prevention and treatment of injury caused by high altitude hypoxia has attracted wide attention.It has shown that the higher the altitude with the longer the duration of exercise,the faster the stationing,the greater the impact on people's sports performance.Rapid entry into the plateau and long-term stay in the plateau have an impact on people's explosive power,endurance and fine operation.Advances in medical technology enable various prevention methods to be used to acclimate to high altitude environments.However,in vitro intervention methods are costly,easy to rebound and possess limited effects.Therefore,drug prevention and treatment is obviously a more economical choice.Chemical drugs increase the efficiency of high altitude exercise by improving the ischemic and hypoxic symptoms of the heart and brain,increasing lung ventilation and arterial oxygenation capacity,and accelerating the elimination of adverse product accumulation after exercise.Single Chinese medicine,Chinese patent medicine,and compound preparations can improve exercise performance by promoting body metabolism,improving muscle endurance,enhancing immunity,and other mechanisms.Traditional Chinese medicine has unique advantage and application prospect in improving plateau sports performance damage.

Objective:To investigate the clinical and pathological characteristics and prognosis of upper tract urothelial carcinoma (UTUC) with concurrent other histological variants.Methods:The clinical data of 566 UTUC patients admitted to Peking University People's Hospital from January 2007 to April 2021 were retrospectively analyzed. Among them, 289 were males and 277 were females, with an average age of (67.3±10.0)years old. Among the patients, 97 had a history of smoking, 29 had undergone kidney transplantation, 120 had diabetes, 76 had coronary heart disease, 146 had hyperlipidemia, 271 had hypertension, and 50 had a history of chronic kidney disease. Among the UTUC cases, 366 had concurrent hydronephrosis, 55 had concurrent bladder cancer, and 43 had a history of previous bladder cancer. The distribution included 210 cases of renal pelvis carcinoma, 5 cases of carcinoma at the renal pelvis-ureter junction, 226 cases of ureteral carcinoma, and 125 cases of multifocal tumors. Patients were classified into the pure UTUC group and the UTUC with concurrent other histological variants group based on postoperative pathology, and their clinical and pathological features were compared. Logistic regression analysis was used to explore risk factors for the occurrence of histological variations in UTUC. The log-rank test was employed to compare the overall survival (OS) and cancer-specific survival (CSS) between the two groups, while Cox regression analysis was performed to investigate prognostic factors.Results:Among the 566 cases, 511 were pure UTUC and 55 were UTUC with concurrent other histological variants. Among the latter, 30 cases had squamous differentiation, 6 had glandular differentiation, 5 had mucinous differentiation, 5 had sarcomatoid carcinoma, 2 had micropapillary carcinoma, 2 had neuroendocrine carcinoma, 1 had giant cell carcinoma, and 4 had other mixed histological variations. The proportion of patients with a history of kidney transplantation was higher in the UTUC with concurrent histological variants group than that in the pure UTUC group [14.5% (8/55) vs. 4.1% (21/511)], with statistically significant difference ( P=0.003). In the UTUC with concurrent histological variants group, the proportion of postoperative high-grade tumors [98.2% (54/55) vs. 80.2% (410/511)], muscle-invasive tumors [89.1% (49/55) vs. 68.1% (348/511)], lymph node metastasis tumors [10.9% (6/55) vs. 2.3% (12/511)], and maximum tumor diameter [(3.60±2.64) cm vs. (2.96±1.98) cm] were higher than those in the pure UTUC group ( P<0.05). Multivariate logistic regression analysis showed that a history of kidney transplantation ( OR=4.991, 95% CI 1.749-13.615, P=0.002) was an independent predictive factor for the occurrence of histological variants. Follow-up was conducted for 1 to 174 months, with a median follow-up time of 32.8 months. UTUC with concurrent histological variants was significantly associated with worse OS and CSS ( P<0.05). Multivariate Cox regression analysis indicated that histological variants were an independent risk factor for OS ( HR=1.860, 95% CI 1.228-2.816, P=0.003) and CSS ( HR=2.146, 95% CI 1.349-3.412, P=0.001). Conclusions:UTUC with concurrent other histological variants exhibited higher postoperative tumor grade and stage compared to pure UTUC, and UTUC with concurrent other histological variants was an independent risk factor for worse prognosis.

Review of historical literature showed that the understanding of the indicated disease location of Modified FuMai Decoction （复脉汤加减方） has evolved from the upper jiao （焦） to the middle and lower jiao. Initially， it is used for the treatment of yin deficiency of both yin and yang in the upper jiao， changes to supplement stomach and produce fluids in the middle jiao， and is used to protect yin， clear the pathogens， conslidate yin and subdue yang so as to store the true yin of lower jiao. The unchanging principle of Fumai Decoction modifications is nourishing yin， while the changing aspects are determining the secondary treatment methods based on disease location of sanjiao， concomitant disease natures， internal injury or external contraction， warm disease or cold damage， thereby choosing the corresponding added or subtracted herbs， and providing reference for the application of classical formulas.

Objective:To investigate the prognosis of robotic pancreatoduodenectomy after the learning curve and open pancreatoduodenectomy for pancreatic cancer.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 396 patients who underwent curative pancreatoduodenectomy for pancreatic duct adenocar-cinoma in Ruijin Hospital of Shanghai Jiaotong University School of Medicine from January 2017 to December 2018 were collected. There were 244 males and 152 females, aged 64(range, 36?92)years. Of 396 patients, 86 cases undergoing robotic pancreatoduodenectomy were divided into robotic group, 310 cases undergoing open pancreatoduodenectomy were divided into open group. Observa-tion indicators: (1) propensity score matching and comparison of general data between the two groups after matching; (2) follow-up and survival analysis. Follow-up was conducted by telephone interview or outpatient examinations including tumor markers and abdominal imaging examina-tions to detect survival of patients up to March 2022. Overall survival was defined as the time from the surgery date to death or the last follow-up. Disease-free survival was defined as the time from the surgery date to tumor recurrence or the last follow-up. The propensity score matching was conducted by 1∶1 matching using the nearest neighbor method. Normality of measurement data was examined using the Shapiro-Wilk test. Measurement data with skewed distribution were described as M(range), and comparison between groups was analyzed using the Mann-Whitney rank-sum test. Count data were represented as absolute numbers, and comparison between groups was analyzed using the chi-square test. Kaplan-Meier method was used to calculate survival rates and draw survival curves, and Log-Rank test was used for survival analysis. An intent-to-treat analysis was performed in this study, patients who were converted to laparotomy from robotic surgery were still divided into the robotic group. Results:(1) Propensity score matching and comparison of general data between the two groups after matching: 164 of 396 patients had successful matching, including 82 cases in robotic group and open group, respectively. Before propensity score matching, the body mass index, cases in stage T1, T2, T3, T4, cases in N0, N1, N2 were 23.4(range, 21.4?25.3)kg/m 2,24, 41, 10, 11, 52, 27, 7 for the robotic group, versus 22.4(range,20.3?23.9)kg/m 2,57, 144, 22, 87, 131, 132, 47 for the open group, showing significant differences in the above indicators between the two groups ( Z=3.01, 2.63, 3.03, P<0.05). After propensity score matching, cases of males, age, body mass index, cases with American Society of Anesthesiologists (ASA) score as 1, 2, 3, CA19-9, cases with preoperative biliary drainage, cases with portal vein resection, cases with pancreatic resection margin <1 mm, cases in stage T1, T2, T3, T4, cases in stage N0, N1, N2, cases with nerve invasion, cases with tumor differentiation as high-medium differentiation, medium-low differentiation, low differentiation, cases with adjuvant chemotherapy were 51, 65(range, 59?69)years, 23.0(range, 21.0?25.2)kg/m 2, 32, 41, 9, 160.4(range, 46.7?377.2)U/mL, 21, 9, 8, 21, 40, 10, 11, 48, 27, 7, 76, 26, 47, 9, 53 for the robotic group, versus 58, 65(range, 58?69)years, 23.3(range, 21.4?25.3)kg/m 2, 35, 39, 8, 172.0(range, 69.7?402.9)U/mL, 26, 9, 10, 24, 40, 7, 11, 49, 28, 5, 76, 22, 49, 11, 57 for the open group, showing no significant difference in the above indicators between the two groups ( χ2=1.34, Z=0.18, 0.34, 0.49, 0.51, χ2=0.75, 0.00,0.25, Z=0.59, 0.27, χ2=0.00, Z=0.76, χ2=0.44, P>0.05). (2) Follow-up and survival analysis: after propensity score matching, 164 patients were followed up for 54(range, 1?67)months. The follow-up time of patients was 55(range, 51?59)months for the robotic group, versus 54(range, 50?58)months for the open group, respectively, showing no significant difference between the two groups ( Z=0.48, P>0.05). During the follow-up, the 1-year overall survival rate, 3-year overall survival rate, the median survival time, 1-year disease-free survival rate, 3-year disease-free survival rate, the median disease-free survival time, tumor recurrence rate, cases with recurrence pattern as local recurrence, liver recurrence, other distant recurrence, local and distant recurrence were 81.7%, 39.0%, 27 months(95% confidence interval as 19?33 months), 61.0%, 34.2%, 15 months(95% confidence interval as 12?18 months), 54.9%(45/82), 12, 16, 9, 8 for the robotic group. The above indicators were 79.3%, 36.0%, 24 months(95% confidence interval as 19?31 months), 59.8%, 27.5%, 15 months(95% confidence interval as 10?20 months), 58.5% (48/82), 10, 22, 6, 10 for the open group. There was no significant difference in overall survival or disease-free survival between the two groups ( χ2=0.39, 0.47, P>0.05). There was no significant difference in tumor recurrence rate or tumor recurrence site between the two groups either ( χ2=0.22, 1.86, P>0.05). Conclusion:After the learning curve, robotic pancreato-duodenectomy has non-inferior prognosis compared with open pancreatoduodenectomy.
