Objective To observe the clinical effect and safety of Wenxin formula in the treatment of stable coronary heart disease angina patients with Syndrome of Yang deficiency with stagnation of the Blood and retention of Phlegm (SYBP). Methods A total of 65 stable coronary heart disease angina patients with SYBP were randomly assigned to the trial group and the control group (34 in the trial group and 31 in the control group). The trial group was treated with Wenxin formula, while the control group was treated with atorvastatin. The treatment lasted 4 weeks. The therapeutic effects on angina, reduction of Nitroglycerin, changes of electrocardiogram (ECG) and TCM syndrome score were observed before and after treatment.ResultsAfter treatment, the trial group had a similar effect with the control group in the aspects of the therapeutic effects on angina, reduction of Nitroglycerin and the ECG change. There was no statistical difference between the two groups (P>0.05). The changes of TCM syndrome score in the trial group was superior to the control group (P<0.05). The total effective rates of the trial group and the control group were 88.2% and 74.2%. The significant efficiency of the treatment group (29.41%) was significantly superior to the control group (9.68%) (P<0.05). No adverse reaction occurred during the therapeutic course.Conclusions The Wenxin formula was safe and effective in the treatment of stable coronary heart disease angina patients with SYBP.

Objective:To investigate the clinical effect of repairing postoperative nasal skin cancer defect with subcutaneous pedicle flap based on partition and blood supply.Methods:From March 2018 to September 2020, 39 patients with skin cancer (basal cell carcinoma, Bowen′s disease, squamous cell carcinoma and malignant melanoma in situ) were repaired with kites subcutaneous pedicle flap after extensive resection.Results:Thirty-nine patients were treated with parafasal kite flaps, including 44 cases. The donor sites of the flap were nasal tip in 4 cases, bilateral alar in 7 cases, bilateral nasolabial sulcus in 19 cases, bilateral parasinal in 12 cases and interglabellar in 2 cases. There were no serious complications such as necrosis, hematoma or infection. During the follow-up period of 6 to 24 months, 2 patients complained of occasional tingling in the surgical area, 1 complained of occasional pruritus, and 1 patient had local recurrence of squamous cell carcinoma and underwent surgery again. The scar was evaluated 6 months after surgery, and the scores of Vancouver scar scale and visual analogue scale were 2.42±1.04 and 7.83±1.21, respectively. The skin color of the operation area was similar to that of the surrounding skin without obvious local strain deformation.Conclusions:The subcutaneous pedicle flap designed by considering the nasal division and blood supply has a high survival rate, fewer complications and small local appearance deformation, which is worthy of popularization and application.

ObjectiveTo explore the therapeutic effect of Xuebijing injection （XBJ） on severe acute pancreatitis induced acute lung injury （SAP-ALI） by regulating formyl peptide receptors （FPRs）/nucleotide-binding oligomerization domain-like receptor 3 （NLRP3） inflammatory pathway. MethodsSixty rats were randomly divided into a sham group， a SAP-ALI model group， low-， medium-， and high-dose XBJ groups （4， 8， and 12 mL·kg^-1）， and a positive drug （BOC2， 0.2 mg·kg^-1） group. For the sham group， the pancreas of rats was only gently flipped after laparotomy， and then the abdomen was closed， while for the remaining five groups， SAP-ALI rat models were established by retrograde injection of 5% sodium taurocholate （Na-Tc） via the biliopancreatic duct. XBJ and BOC2 were administered via intraperitoneal injection once daily for 3 d prior to modeling and 0.5 h after modeling. Blood was collected from the abdominal aorta 6 h after the completion of modeling， and the expression of interleukin （IL）-1β， IL-6， and tumor necrosis factor-α （TNF-α） in plasma was measured by enzyme-linked immunosorbent assay （ELISA）. The amount of ascites was measured， and the dry-wet weight ratios of pancreatic and lung tissue were determined. Pancreatic and lung tissue was taken for hematoxylin-eosin （HE） staining to observe pathological changes and then scored. The protein expression levels of FPR1， FPR2， and NLRP3 in lung tissue were detected by the immunohistochemical method. Western blot was used to detect the expression of FPR1， FPR2， and NLRP3 in lung tissue. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of FPR1， FPR2， and NLRP3 in lung tissue. ResultsCompared with the sham group， the SAP-ALI model group showed significantly decreased dry-wet weight ratio of lung tissue （P<0.01）， serious pathological changes of lung tissue， a significantly increased pathological score （P<0.01）， and significantly increased protein and mRNA expression levels of FPR1， FPR2， and NLRP3 in lung tissue （P<0.01）. After BOC2 intervention， the above detection indicators were significantly reversed （P<0.01）. After treatment with XBJ， the groups of different XBJ doses achieved results consistent with BOC2 intervention. ConclusionXBJ can effectively improve the inflammatory response of the lungs in SAP-ALI rats and reduce damage. The mechanism may be related to inhibiting the expression of FPRs and NLRP3 in lung tissue， which thereby reduces IL-1β and simultaneously antagonize the release of inflammatory factors IL-6 and TNF-α.
