Pulmonary sarcoidosis is an immune system disease with an unclear etiology. Guided by the yang-reinforcing method， it is believed that the fundamental pathogenesis of pulmonary sarcoidosis lies in the disharmony between water and fire and the reckless movement of the ministerial fire. The failure of the spleen and stomach to maintain warmth， leading to the production of phlegm and blood stasis， is an important pathogenesis. The invasion of external pathogenic toxins， deeply penetrating into the interior， is considered a triggering factor for the disease. The treatment focuses on supplementing the yang， consolidating the kidney， drawing fire back to its source， warming the yang， benefiting the kidney， and nourishing the spleen to generate metal. It also emphasizes unblocking the yang， transforming turbidity， and eliminating phlegm and blood stasis.

This article is based on ZHANG Jingyue's theory of yin-yang holism to explore the etiology， pathogenesis， and treatment of acute exacerbation of rheumatoid arthritis-associated interstitial lung disease （RA-ILD）. It is believed that the foundation of acute exacerbation of RA-ILD lies in real yin insufficiency and yin fail to control yang； external pathogen attacking is a common cause of acute exacerbation of RA-ILD. For treatment， it is important to first suppress ministerial fire by prescribing modified Yinhuo Decoction （引火汤）； if ministerial fire submerged， focus should be on nourishing both yin and yang； if real yin deficiency is the main issue， modified Zuogui Pill （左归丸） should be used； if real yang deficiency is prominent as well， modified Yougui Pill （右归丸） can be chosen. When yin and yang balanced， the disease could be solved.

Refractory chronic cough belongs to the category of "refractory cough" in traditional Chinese medicine， and it is believed that the root cause of intractable chronic cough is wind lodging in the spleen collaterals， with poor spleen yang and deficient kidney essence as the pathologic basis of the disease， which is present throughout the disease. The method advocated is to search the spleen collaterals and eliminate latent wind， warm the spleen yang and smooth the middle jiao， cultivate the kidney essence and consolidate the root， prescribed with modified Fuzi Lizhong Decoction （附子理中汤） plus Erxian Decoction （二仙汤） as the basis. The Fuzi Lizhong Decoction can warm yang and fortify the middle， and smooth the middle jiao， and the Erxian Decoction can cultivate the kidney essence and consolidate the innate. The two prescriptions could combine with Suye （Perilla frutescens）， Jingjie （Dysphania ambrosioides）， Fangfeng （Carum carvi） and other medicinals of cleaning characteristic， or combine with Gouteng （Uncaria rhynchophylla）， Chuanshanlong （Dioscorea nipponica）， Dilong （Kummerowia striata） and other medicinals of worm or cane category， to find the wind and expel pathogen， smooth spleen collaterals.

It is believed that the fundamental pathogenesis of the connective tissue diseases-associated interstitial lung disease （CTD-ILD） is kidney essence deficiency， with lung collateral obstruction throughout the disease， and environmental toxin pathogen is the important causative factors for the development of CTD-ILD. This article proposed to restore origin and alleviate bi （痹） for CTD-ILD， for which restoring origin means tonifying the lungs， spleen and kidneys to bank up the roots and consolidate the original qi， with modified Erxian Decoction （二仙汤） plus Liu Junzi Decoction （六君子汤）； alleviating bi means expelling wind and dredging collaterals， and eliminating the mass to restore the smoothness of the lung collaterals， with paired medicines of Chuanshanlong （Dioscorea nipponica）-Dilong （Kalanchoe pinnata）， Vinegar-processed Sanleng （Sparganium stoloniferum）-Vinegar-processed Ezhu （Curcuma zedoaria）， and stem-type medicines， and emphasized on removing the environmental toxin pathogens to facilitate the recovery of healthy qi.

Object:To explore surgical treatments for duodenal fistula with intra-abdominal infection.Methods:The data of 19 patients with duodenal fistula treated at the Affiliated Tumor Hospital of Zhenzhou University between Jan 2015 and Dec 2021 were analyzed retrospectively. Surgery is performed with duodenostomy or modified duodenal shunt procedures.Result:All patients were accompanied by intra-abdominal infection, including 9 duodenal stump fistulas. All patients successfully completed the operation,11cases underwent duodenostomy, 8 case underwent modified duodenal shunt procedures. operating time was 110(60-140)min, postoperative hospitalization time was 29(9-103)d. Two patients died postoperatively. Fistula heals in other patients.Conclusion:Surgical intervention for duodenal fistula should focus on controlling the source of infection, strengthening intestinal and abdominal drainage, and reducing postoperative complications.

Objective:To analyze the value of shear wave elastography (SWE) in evaluating carotid artery elasticity in type 2 diabetes mellitus (T2DM) patients with nonalcoholic fatty liver disease (NAFLD).Methods:A total of 98 T2DM patients diagnosed in the Second Affiliated Hospital of Dalian Medical University were selected and divided into three groups according to the results of liver ultrasound examination. 35 patients without NAFLD were in group A, 33 patients with mild NAFLD were in group B, and 30 patients with moderate to severe NAFLD were in group C. All selected individuals showed no plaque formation on carotid ultrasound examination. Left carotid artery intima-media thickness (IMT), carotid artery systolic diameter (Ds), carotid artery diastolic diameter (Dd), and peak systolic velocity (PSV) were measured using conventional two-dimensional and M-mode ultrasound. The stiffness coefficient (β) was obtained through calculation. SWE was used to measure the mean longitudinal modulus of elasticity (MEmean), mean minimum modulus of elasticity (MEmin), and mean maximum modulus of elasticity (MEmax) of the left carotid artery at the end of diastole.Results:There was no statistically significant difference in Ds, Dd, and PSV among the three groups (all P>0.05). Compared with group A and group B, group C had significantly higher IMT, β, MEmean, MEmax, and MEmin (all P<0.05). Compared with the group A, the group B had higher levels of MEmean, MEmax, and MEmin (all P<0.05), there was no statistically significant difference in IMT and β between the groups (all P>0.05). Correlation analysis showed that MEmax, MEmean, and MEmin in each group were positively correlated with β ( r=0.537, 0.543, 0.525, P<0.01), and also positively correlated with HbA 1c ( r=0.456, 0.483, 0.438, P<0.01), but not with IMT (all P>0.05). The intra observer Intraclass correlation coefficient (ICC) of MEmax, MEmean and MEmin measured by SWE was 0.847-0.887, and the inter observer ICC was 0.791-0.934, indicating a good repeatability. Conclusions:SWE can quantitatively evaluate the elasticity of the carotid artery in patients with T2DM and NAFLD.

Bronchiectasis is a refractory chronic airway disease characterized by chronic cough and phlegm production. Airway mucus hypersecretion is one of the important causative factors for acute exacerbation of bronchiectasis. Thus， reducing airway mucus secretion during the stable phase of bronchiectasis is the key to the treatment. Phlegm-dispelling therapy is commonly used in modern medicine， which， however， fails to radically reduce mucus secretion. At the moment， it is difficult and urgent to find an intervention that can improve the quality of life of patients and reduce the recurrence of disease during the stable phase of bronchiectasis. Chinese medicine shows remarkable efficacy in reducing airway mucus secretion. Nonetheless， there is a lack of research on the airway mucus hypersecretion of bronchiectasis， and no registered research outcome is available. Traditional Chinese medicine boasts a lot of experience in the treatment of phlegm. It combines clearing and tonifying methods and identifies Yin and Yang and internal organs， thus being advantageous in the treatment of airway mucus hypersecretion of bronchiectasis. Therefore， it is an important topic to improve the effectiveness of Chinese medicine on airway mucus hypersecretion of bronchiectasis by focusing on the "generation"， "transformation" and "excretion" of phlegm.

Objective:Three-dimensional speckle tracking echocardiography (3D-STE) was used to evaluate the left ventricular function in patients with triple vessel coronary artery disease without myocardial infarction.Methods:60 patients with three vessel disease of coronary heart disease without myocardial infarction treated in the Second Affiliated Hospital of Dalian Medical University from June 2018 to December 2020 were selected. They were divided into two groups according to the results of coronary angiography. There were 31 cases in group B, and the stenosis rate of all triple vessel coronary artery was 50%-<75%; 29 cases in group C, the stenosis rate of all triple vessel coronary artery was ≥75%; Thirty healthy subjects were recruited as the group A. We measured left ventricular (LV) end-diastolic and end-systolic volume (LVEDV, LVESV) and LV ejection fraction (LVEF) using real-time dynamic three-dimensional echocardiography. The LV strain parameters were acquired by 3D-STE, including global longitudinal strain (GLS), global area strain, global radial strain (GRS) and global circumferential strain (GCS). The correlation between 3D-STE parameters and N-terminal proBNP (NT-proBNP), left ventricular end-diastolic pressure (LVEDP) were analyzed by Pearson linear correlation analysis.Results:The LVEDV and LVESV in group A and B were significantly lower than those in group C (all P<0.05), and the absolute values of LVEF, GLS, GRS, GCS and GAS were higher than those in group C (all P<0.05). There were no significant difference in LVEDV, LVESV and LVEF between group B and group A (all P>0.05), while the absolute values of GLS, GCS and GAS in group B were significantly lower than those in group A (all P<0.05). The absolute values of GLS, GRS, GCS and GAS in group C were negatively correlated with NT-proBNP and LVEDP (all P<0.05). The absolute value of GLS in group B was negatively correlated with NT-proBNP ( P<0.05), and the absolute value of GLS, GRS, GCS and GAS was negatively correlated with LVEDP (all P<0.05). Conclusions:Our study shows that 3D-STE can evaluate the LV function in patients with triple vessel coronary artery disease without myocardial infarction through multiple strain parameters.

Objective:To evaluate the strategy and skills of reoperation for recurrent carcinoma at the stoma of esophagojejunostomy after total gastrectomy.Methods:The management experience in 18 patients at the Department of General Surgery, Tumor Hospital of Zhengzhou University from Oct 2016 to Jul 2021 were analyzed retrospectively.Results:Thirteen patients underwent left thoracoabdominal combined incision to completely remove the tumor.One patient developed anastomotic leakage, two patients developed pulmonary infection, one patient developed costochondritis, all were cured and discharged after conservative treatment; Nine patients had no postoperative complications. Two patients abandoned surgery due to high position of the tumor, 3 patients due to poor cardiopulmonary function, and were given radiotherapy and chemotherapy.The postoperative follow-up period was 4.6 to 42.9 months. Four patients died of tumor recurrence, and the remaining patients survived until the end of the follow-up. The overall 1-and 3-year recurrence-free survival rates were 100% and 20%, respectively.Conclusion:Surgery on recurrent carcinoma at esophagojejunostomy stoma after total gastrectomy, although difficult and challenging,could still benefit most patients when at the hands of expertise.
