ObjectiveTo investigate the clinical efficacy and safety of Qihuang Jianpi Zishen granules in the treatment of cardiac involvement in systemic lupus erythematosus (SLE). MethodA total of 62 SLE patients with cardiac involvement treated in the Department of Rheumatology and Immunology, the First Affiliated Hospital of Anhui University of Chinese Medicine from June 2021 to December 2022 were randomized into control and observation groups (n=31). The control group was treated with methylprednisolone tablets and hydroxychloroquine sulfate tablets, and the observation group with Qihuang Jianpi Zishen granules on the basis of the therapy in the control group. After 12 weeks of treatment, the two groups were compared in terms of the therapeutic effect, cardiac function indicators [left atrial end-diastolic diameter (LADd), left ventricular end-diastolic diameter (LVDd), left ventricular posterior wall thickness (LVPWTd), peak blood flow velocity in early diastolic period (peak E), peak blood flow velocity in late diastolic period (peak A), E/A ratio, stroke volume (SV), left ventricular ejection fraction (LVEF), left ventricular short axis shortening rate (LVFS), and B-type natriuretic peptide (BNP)], vascular damage indicators [nitric oxide (NO), endothelin-1 (ET-1), vascular endothelial growth factor (VEGF), and homocysteine (Hcy)], inflammation indicators [erythrocyte sedimentation rate (ESR) and hypersensitive C-reactive protein (Hs-CRP)], anti-double-stranded DNA (dsDNA) antibodies, disease activity index (SLEDAI) score, mitigation of symptoms and signs, and occurrence of adverse reactions. ResultThe total response rate in the observation group was 87.09%, which was higher than that (67.74%) in the control group (P<0.01), and the incidence of adverse reactions had no significant difference between the two groups. After treatment, the control group showed lowered LVDd, LVPWTd, BNP, ET-1, VEGF, and Hcy (P<0.05) and increased E peak, E/A ratio, SV, LVEF, and LVFS (P<0.05). In the observation group, LADd, LVDd, LVPWTd, peak A, BNP, NO, ET-1, VEGF, and Hcy decreased (P<0.05), while peak E, E/A ratio, SV, LVEF and LVFS increased (P<0.05) after treatment. The treatment in both groups decreased the scores of palpitation, chest tightness, dyspnea, and edema (P<0.05), reduced ESR, Hs-CRP, ds-DNA, and SLEDAI (P<0.05). After treatment, the observation group had lower LADd, LVDd, LVPWTd, peak A, BNP, and scores of palpation, chest tightness, dyspnea, and edema (P<0.05) and higher peak E, E/A ratio, SV, LVEF, and LVFS (P<0.05) than the control group. In addition, the observation group had lower NO, ET-1, VEGF, Hcy, ESR, Hs-CRP, ds-DNA, and SLEDAI than the control group (P<0.05). ConclusionQihuang Jianpi Zishen granules combined with hydroxychloroquine sulfate and methylprednisolone can improve multiple indicators and mitigate the symptoms and signs of SLE patients with cardiac involvement, demonstrating a clinical application value.

Accurate segmentation of pediatric echocardiograms is a challenging task, because significant heart-size changes with age and faster heart rate lead to more blurred boundaries on cardiac ultrasound images compared with adults. To address these problems, a dual decoder network model combining channel attention and scale attention is proposed in this paper. Firstly, an attention-guided decoder with deep supervision strategy is used to obtain attention maps for the ventricular regions. Then, the generated ventricular attention is fed back to multiple layers of the network through skip connections to adjust the feature weights generated by the encoder and highlight the left and right ventricular areas. Finally, a scale attention module and a channel attention module are utilized to enhance the edge features of the left and right ventricles. The experimental results demonstrate that the proposed method in this paper achieves an average Dice coefficient of 90.63% in acquired bilateral ventricular segmentation dataset, which is better than some conventional and state-of-the-art methods in the field of medical image segmentation. More importantly, the method has a more accurate effect in segmenting the edge of the ventricle. The results of this paper can provide a new solution for pediatric echocardiographic bilateral ventricular segmentation and subsequent auxiliary diagnosis of congenital heart disease.

Objective To investigate the expression levels of scf and c-kit under the regulation of Dahuang Lingxian prescription and the possible mechanism of its effect on gallbladder dynamics, and to provide a theoretical basis for Dahuang Lingxian prescription in preventing the development and recurrence of cholesterol gallstone. Methods A total of 45 specific pathogen-free healthy male guinea pigs were randomly divided into normal group, model group, and traditional Chinese medicine (TCM) group. The guinea pigs in the normal group were fed with normal diet, and those in the model group and the TCM group were fed with high-fat lithogenic diet. After 8 weeks of feeding, 5 guinea pigs were randomly selected from each group, and successful modeling was determined if gallstone was observed with the naked eye in more than 4 guinea pigs. After successful modeling, the guinea pigs in the TCM group were given Dahuang Lingxian prescription by gavage, and those in the model group were given an equal volume of normal saline by gavage. After 8 consecutive weeks of administration by gavage, gallbladder tissue samples were collected, and HE staining was used to observe the pathological changes of gallbladder tissue; Western blot was used to measure the expression level of tumor necrosis factor-α (TNF-α) in gallbladder tissue; immunohistochemistry was used to measure the protein expression levels of scf and c-kit in gallbladder smooth muscle tissue. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference multiple comparison method was used for further comparison between two groups. Results HE staining showed marked inflammation of gallbladder tissue in the model group, and compared with the model group, the TCM group had a significantly lower degree of inflammation. Western blot showed that the model group had the highest expression level of TNF-α in gallbladder tissue, followed by the TCM group and the normal group ( P < 0.05); immunohistochemistry showed that compared with the model group, the normal group and the TCM group had significantly higher protein expression levels of scf and c-kit in gallbladder smooth muscle tissue ( P < 0.05). Conclusion Dahuang Lingxian prescription can enhance the dynamic function of the gallbladder, possibly by upregulating the scf/c-kit signaling pathway in interstitial cells of Cajal in gallbladder.

OBJECTIVE: To study the improvement effects of fibrinolytic enzyme from Sipunculus nudus (SNFE) on hemorheology disorder and vascular endothelium injury in naked acute blood stasis model rats. METHODS: SD rats were randomly divided into control group, model group, aspirin group (100 mg/kg) and SNFE high-dose and low-dose groups (2 500, 5 000 U/kg), with 10 rats in each group. They were given relevant medicine intragastrically once a day, for consecutive 7 d. One hour after the 6th day of administration, except for control group, other groups were given adrenaline hydrochloride 0.8 mg/kg subcutaneously, and then the acute blood stasis model was induced by ice-water bath. Blood was collected from abdominal aorta 2 h after the next day. Blood rheological parameters such as whole blood viscosity (high, medium and low shear rate), plasma viscosity, hematocrit, erythrocyte aggregation index and erythrocyte deformability index were measured by automatic rheometer. The contents of NO and ET-1 in plasma and their ratio were determined by ELISA, and the damaged degree of vascular endothelium were observed by HE staining. RESULTS: Compared with control group, whole blood viscosity of high, medium and low-shear rate, plasma viscosity, erythrocyte aggregation index and ET-1 content were increased significantly in model group, while erythrocyte deformability index, NO content and NO/ET-1 ratio were decreased significantly, with statistical significance (P<0.05 or P<0.01). Compared with model group, whole blood viscosity of high, medium and low-shear rate, plasma viscosity, hematocrit, erythrocyte aggregation index and ET-1 content were decreased significantly in SNFE high-dose groups. Erythrocyte deformability index, NO content and NO/ET-1 ratio were increased significantly, with statistical significance (P<0.05 or P<0.01). In SNFE low-dose group, erythrocyte deformability index and NO/ET-1 ratio were increased significantly, while ET-1 content was decreased significantly, with statistical significance (P<0.05 or P<0.01). Vascular endothelial staining showed that compared with control group, the structure of aorta layers in model group was loose and disordered, the endothelial defect was incomplete, the vacuoles increased, and the endothelial damage was obvious. The endothelium of rats in each administration group was damaged to varying degrees, but the degree of injury was lighter than in model group. CONCLUSIONS: SNFE can improve hemorheological abnormalities and vascular endothelial injury in rats with acute blood stasis.

OBJECTIVE:To study the anti-coagulation effect and mechanism of fibrinolytic enzyme SNFE in sipuculus nudus, and provide reference for further development of SNFE. METHODS:40 mice were randomly divided into blank control group(nor-mal saline),Xueshuantong group(positive control,15 mg/kg)and SNFE low-dose,high-dose group(15,30 mg/kg),10 in each group. After intravenous injection in tail,tail bleeding time (BT) and clotting time (CT) were respectively determined to investi-gate the anti-coagulation effect of SNFE. After taking blood in abdominal aorta of rats,test was divided into blank control group, positive control group and SNFE low-mass concentration,medium-mass concentration,high-mass concentration groups (0.25, 0.50,1.00 mg/mL). Prothrombin time(PT),re-calcium time(PRT)(using orokinase as positive drug,100000 U/mL),and max-mum platelet aggregation rate (PAG) in 5 min under adenosine diphosphate (ADP) inducer (using asprin as positive drug,0.50 mg/mL) were respectively determined,and anti-coagulation effect mechanism of SNFE was analyzed. RESULTS:Compared with blank control group,BT,CT of mice in each group were prolonged,with statistical significance in Xueshuantong group and SNFE high-dose group (P<0.05 or P<0.01). Plasma PT of rats in positive control group,SNFE medium-dose,high-dose groups and PRT in each administration group were significantly prolonged(P<0.05 or P<0.01);and PAG in administration group was signifi-cantly reduced(P<0.01). CONCLUSIONS:The fibrinolytic enzyme SNFE in sipuculus nudus can play its anti-coagulant effect by inhibiting the activity of coagulation factors in internal and external sources and ADP-induced platelet aggregation.

OBJECTIVETo study retrospectively the clinical efficacy on pediatric recurrent pneumonia treated with point application in summer for the prevention in winter, as well as the relationship of age, sick duration, attack frequency and skin reaction with the clinical efficacy.
METHODSOne hundred and thirty-five cases of pediatric recurrent pneumonia were divided into a one-year group, a two-year group and a three-year group, 45 cases in each one according to the duration of treatment. The acupoints for the application were Dingchuan (EX-B1), Feishu (BL 13), Gaohuang (BL 43) and Danzhong (CV 17) with the same herbal plaster (prepared with rhizome corydalis, semen brassicae, euphorbia kansui and asarum sieboldii at the ratio of 2:2:1:1) on the first day of each of the three periods of the hot season, 2 to 4 h in each treatment. The attack frequency and change rate were observed before and after treatment in the three groups. The clinical efficacy was assessed in the three groups.
RESULTS(1) After treatment, the attack frequency of pediatric pneumonia was reduced apparently in the three groups (all P < 0.01). The result in the three-year group was less than that in the one-year group and the two-year group and the change rate was the highest (all P < 0.01). (2) After treatment, the sick duration was shortened apparently in the three groups (P < 0.05, P < 0.01). The result in the three-year group was the most remarkable, statistically and significantly different as compared with the other two groups (both P < 0.01). (3) The total effective rate in the three-year group was better than that in either of the other two groups [84.4% (35/45) vs 51.1% (23/45, P < 0.01), 84.4% (35/45) vs 71.1% (32/45, P < 0.05)]. (4) The total effective rate in the children aged from 4 to 7 years was better than that in the group aged from 8 to 10 years and the group aged from 11 to 14 years [79. 7% (47/59) vs 71.7% (33/46, P < 0.05); 79.7% (47/59) vs 43.3% (13/30, P < 0.01)]. (5) The total effective rate in the children with the sick duration ≥ 4 year was lower than that in the group with the sick duration <2 years and that 2 to 4 years (both P < 0. 01). (6) The total effective rate in the children with the annual attack frequency of 2 to 4 times was better than that with the frequency ≥ 4 times (P < 0.01). (7) For the cases with skin reaction after treatment, the total effective rate was better than that in the cases without reaction (P < 0.05).
CONCLUSIONThe point application in summer for the prevention in winter reduces the attack frequency of pediatric pneumonia, shortens the sick duration and has achieved the better significant efficacy in the cases of lower age, shorter sick duration, less attack frequency and moderate skin reaction.
