ObjectiveTo investigate the effect of different degrees of pressure of sustained inflation (SI) in patients with acute respiratory distress syndrome (ARDS) after lung recruitment as the result of different negative pressure for sputum aspiration.Methods A prospective single-blind randomized controlled trial was conducted. The factorial analysis of variance was adopted. 150 patients with ARDS admitted to the emergency intensive care unit (ICU) of Chongqing Three Gorges Central Hospital from January 2012 to December 2014 were enrolled, and they were randomly divided into S1, S2, S3 group, with 50 patients in each group, suction pressure varying from 150, 175, to 200 mmHg (1 mmHg = 0.133 kPa) was respectively used in each group. Then the patients of each group were randomly subdivided into five subgroups of P0, P1, P2, P3, P4, with 10 patients in each group, and 0, 30, 35, 40, and 45 cmH2O (1 cmH2O = 0.098 kPa) were used for control pulmonary inflation pressure, respectively. The respiratory mechanics and the hemodynamic parameters were recorded, and they were compared before and after the sputum aspiration as well as lung recruitment with sustained inflation.Results The lung recruitment volume (mL: 87.56±28.47 vs. 109.38±34.63, t = 3.573,P = 0.001) and lung static compliance [Cst ( mL/cmH2O): 27.69±13.25 vs. 35.87±17.47,t = 2.814,P = 0.004] after sputum aspiration in the 150 patients were significantly lower than those before the sputum aspiration, and peak airway pressure [PIP (cmH2O): 24.16±8.28 vs. 18.63±6.67,t = 2.957,P = 0.005], airway plateau pressure [Pplat (cmH2O): 21.28±9.14 vs. 17.47±7.26,t = 2.089,P = 0.032], and mean airway pressure [Pm (cmH2O): 13.26±4.65 vs. 10.41±3.54,t = 3.271,P = 0.001] were significantly higher than those before the treatment. There were no significant differences in the lung recruitment volume, Cst, PIP, Pplat and Pm between groups with different negative pressure for sputum aspiration (F value was 0.809, 0.986, 1.121, 0.910, 1.043, andP value was 0.452, 0.381, 0.335, 0.410, 0.361), but statistical significance was found among different groups of different lung recruitment pressures (F value was 3.581, 5.028, 3.064, 3.036, 4.050, andP value was 0.013, 0.002, 0.026, 0.027, 0.007). There was no interaction between the two factors. After pairwise comparison, under the same negative pressure for sputum aspiration, lung recruitment volume and Cst in different lung recruitment pressures subgroups (P1, P2, P3, P4) were significantly higher than those of P0 subgroup, and PIP, Pplat, and Pm were significantly lower than those of P0 subgroup. There was no significant difference among P1, P2, P3 and P4 groups. There were no significant differences in mean arterial pressure (MAP) and pulmonary arterial pressure (PAP) among different groups with negative pressures for sputum aspiration and different lung recruitment pressures (negative pressure for sputum aspiration:F = 0.586,P = 0.561,F= 1.373,P = 0.264; lung recruitment pressure:F = 1.313,P = 0.280,F= 1.621,P = 0.186), there was no interaction between the two factors (F = 0.936,P = 0.497,F = 1.391,P = 0.227). The difference of heart rate (HR) in different negative pressure for sputum aspiration groups was not significant (F = 1.144,P = 0.328), and there were significant differences in different lung recruitment pressure groups (F = 3.297,P = 0.019), there was no interaction between the two factors (F = 1.277, P = 0.280). After pairwise comparison, under the same negative pressure for sputum aspiration, HR in P3 and P4 subgroups was significantly higher than that in P0, P1, and P2 subgroups (allP< 0.05).Conclusion 30 cmH2O and 35 cmH2O were the suitable pressure for SI in ARDS patients, and they were not affected by different negative pressure for sputum aspiration.

Objective: To explore the relationship between plasma level of N terminal pro brain natriuretic peptide (NT-proBNP) and severity of coronary artery lesion in patients with coronary heart disease (CHD). Methods: A total of 206 patients suspected CHD, who admitted from Jan 2010 to Jun 2012 in our department and underwent coronary angiography (CAG), were divided into single vessel coronary disease group (n=54), double-vessel coronary disease group (n=52), multi-vessel coronary disease group (n=67) and normal group (n=33), according to CAG examination; and divided into acute myocardial infarction (AMI) group (n=45), unstable angina pectoris (UAP) group (n=91), stable angina pectoris (SAP) group (n=43) and normal group (n=27) according to clinic symptom. All patients received measurement for NT-proBNP, creatine kinase-isoenzyme (CK-MB) and cardiac troponin I (cTnI). Stenotic severity of coronary artery lesion was evaluated using Gensini score method. Data of all groups were analyzed statistically. Results: Compared with SAP group and normal group, there was significant increase in plasma level of NT-proBNP [(2.28±0.22) vs. (2.18±0.69) vs. (2.94±0.24) vs. (2.74±0.15), P<0.01 or P<0.05] in AMI group and UAP group. Compared with normal group, there was significant increase in plasma level of NT-proBNP [ (2.07±0.43) vs. (2.44±0.38) vs. (2.69±0.34) vs. (2.98±0.28), P<0.05] in single, double and multi-vessel coronary disease groups. Plasma level of NT-proBNP was positively correlated with Gensini score (r=0.51, 0.67, 0.73 respectively in single, double and multi-vessel coronary disease group, P<0.05 all). Conclusion: NT-proBNP concentration can be regard as an index predicting severity of coronary artery lesion.

Objective:To investigate the clinical effect of the proximal interphalangeal kite flap in repairing the wound of the posterior web of the split toe.Methods:A retrospective case series study was used to analyze the clinical data of children with syndactyly after toe web wounds were repaired with proximal kite flap between toe webs in the Yidu Central Hospital of Weifang from May 2010 to March 2019. The satisfaction of flap repair effect (the total score is 5-10) and the operation effect according to toe function, toe web slope, and depth were evaluated. The measurement data of normal distribution were expressed in Mean±SD and analyzed by paired sample t-test. Results:A total of 10 children with syndactyly were included, including four males and six females, aged from 6 months to 9 years. Seven cases were on the right side, and there were on the left. All were soft tissue connexions, incomplete syndactyly 6 feet, complete syndactyly 4 feet. All flaps survived and were followed up for an average of 13 months (range, 6-24 months). The score of satisfaction was 8.6±2.7. The appearance, color, elasticity, and texture of the reconstructed web are similar to those of the uninjured side. At the last follow-up, there was no significant difference between the abduction of the separated toe and that of the healthy side (43.57 ± 3.82)° and (44.39 ± 4.25)°( P=0.64). There was no significant difference between the two groups ( P=0.66). The reconstruction depth of the toe web was (1.19 ± 0.23) cm, which was not significantly different from that of the healthy side (1.21 ± 0.27) cm ( P=0.85). Conclusions:The proximal interphalangeal kite flap is one of the ideal methods to repair the wounds of the posterior web of the congenital syndactyly. However, the number of cases in this study is small, and the follow-up time is short. The curative effect of the children with the growth and development process needs further research.

ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.
