Chronic heart failure(CHF)is a common and frequent clinical condition with complex pathogenesis.The micro-inflammatory state exists in the development of CHF and is manifested by a continuous increase in inflammatory proteins and inflammatory cytokines in the circulation,affecting the body's metabolism and immune function.Micro-inflammatory state of CHF belongs to the syndrome of deficiency in nature and excess in superficiality in the TCM field.The basic pathogenesis of CHF is"deficiency qi retention";the nature is the deficiency of heart energy and the superficiality is retention of qi,blood stagnation,phlegm,water and dampness,with"deficiency,stagnation and water"running throughout the disease.Therefore,based on the theory of"deficiency qi retention",this article took"reinforcing deficiency and removing stagnation"as its basic treatment method,regulated the body's immunity and inflammatory indicators such as serum high-sensitivity C-reactive protein,tumor necrosis factor-α,in order to alleviate the micro-inflammatory state,which is of great significance for the prevention and treatment of CHF.

Objective:To evaluate the effectiveness of surgical methods for correcting pollybeak deformity in Chinese rhinoplasty.Methods:A retrospective chart review was conducted for patients who underwent pollybeak correction between January 2021 and December 2022 at the Department of Plastic and Aesthetic (Burn) Surgery, the Second Xiangya Hospital of Central South University. Individualized correction was tailored based on the etiology and severity of the nasal deformity of each patient, involving techniques such as resection of the anterior part of the nasal septum, reconstruction of nasal tip support, reconstruction of the middle part of the nasal vault, and excision of skin in the upper region of the nasal tip. A modified classification system for pollybeak deformity, the supratip fullness rating scale (SFRS), was developed to evaluate supratip fullness (0-3 points, with higher scores indicating more apparent deformity). The patients aesthetic outcomes were assessed by surgeons using the visual analogue scale (VAS) (0-10 points, with higher scores indicating more apparent deformity), and patient self-assessed using the rhinoplasty outcome evaluation (ROE) questionnaire (0-100 points, with higher scores indicating higher satisfaction). The measurement data of normal distribution was expressed as Mean±SD and analyzed by paired t-test; the measurement data of non-normal distribution was expressed as M( Q1, Q3) and analyzed by Wilcoxon signed rank test. Results:In a cohort study of 53 rhinoplasty patients (7 male, 46 female; age range 19-45 years, mean 29 years), comprising 15 primary and 38 secondary surgeries, nasal tip deformities were evaluated. Deformities were classified as mild (5 cases), moderate (25 cases), and severe (23 cases). Over a follow-up period of 6-17 months (mean 9.5 months), significant aesthetic improvements in the nasal tip region were observed. The SFRS scores decreased from 2(2, 3) preoperatively to 0(0, 0) postoperatively ( Z = -6.58, P < 0.001), and VAS scores decreased from 7.47±1.73 to 1.79±1.67 ( t = -25.61, P < 0.001). High patient satisfaction was indicated by a mean ROE score of 82.45±11.55. No significant complications, such as nasal tip ptosis, skin necrosis, or scar hyperplasia, were reported. Conclusion:Selecting an appropriate surgical method based on the severity and cause of pollybeak deformity can achieve satisfactory outcomes. Post-operative patients exhibit significant aesthetic improvement in the upper nasal tip area, resulting in high patient satisfaction.

Objective:To investigate the surgical effect of pedicled upper lip mucosal flap in repairing nasal septal mucosal defects after rhinoplasty.Methods:A retrospective analysis was performed from January 2016 to October 2022, the clinical data of patients with nasal septal mucosal defects after rhinoplasty were collected in the Department of Plastic and Aesthetic (Burn) Surgery at the Second Xiangya Hospital of Central South University. The pedicled upper lip mucosal flap was utilized for repair based on the patient’s medical history and wound condition. The pedicle of the flap was designed 1 cm adjacent to the frenulum of the upper lip, and an appropriate flap was incised based on the size of the wound, with dissection performed up to the superficial layer of the orbicularis oris muscle. The dissection establishes an upper lip tunnel that connects the gingival-buccal groove to the nasal cavity. The pedicled upper lip mucosal flap was elevated and transposed into the nasal cavity via the upper lip tunnel. The position of the flap was adjusted to ensure complete coverage and fixation of the nasal septal defect wound using 5-0 absorbable suture. The visual analogue scale (VAS) and the nasal obstruction symptom evaluation (NOSE) scale were utilized to facilitate patients’ satisfaction evaluation and assessment of nasal obstruction symptoms before surgery and at 6 months post-surgery. The VAS total score was 10 points, with higher scores indicating greater levels of patient satisfaction. The NOSE scale comprises of 5 items, each assigned a score ranging from 0 to 4, denoting absence of symptoms, very mild presence, moderate intensity, relatively severe manifestation, and highly severe indication respectively. The measurement data of VAS and NOSE scores before surgery and at 6 months post-surgery was expressed by Mean±SD, using paired t-test. The score distribution of the NOSE scale was represented by the number of cases, using Mann-Whitney U test. Results:The study included a total of 15 female patients, with an average age of (27.6±2.9) years (ranging from 23 to 33 years). Eleven cases presented with preoperative cartilage exposure, and the size of tissue defect ranged from 0.9 cm×0.5 cm to 1.5 cm×0.7 cm. Nine patients had a history of smoking. Skin grafting was performed in 9 patients, while nasal mucosal metastasis was observed in 8 patients. The dimensions of the flap varied from 4.0 cm×1.2 cm to 7.0 cm×1.5 cm. The postoperative recovery was satisfactory, with successful survival of the skin flaps and no occurrences of infection, hematoma, wound dehiscence, or flap necrosis. The average duration of follow-up was (8.2±2.1) months (ranging from 6 to 12 months). The postoperative VAS score (7.73±0.88) was significantly higher compared to the preoperative score (1.86±0.74) ( P<0.01). Additionally, the postoperative NOSE score (4.66±1.71) showed a significant decrease from the preoperative score (10.73±2.68), with a statistically significant difference ( P<0.01). Among them, after surgery items of stuffy or unbreathable nose (2 cases vs. 15 cases), nasal obstruction (1 case vs. 14 cases), and feeling that the nose was not enough to breathe during exercise or exertion (4 cases vs. 14 cases) scored≥2 points were significantly less than those before operation (all P<0.01). Conclusion:The utilization of pedicled upper lip mucosal flap in the reconstruction of severe nasal septal mucosal defects following rhinoplasty has proven to be highly effective. The postoperative satisfaction of patients is remarkably high, the ventilation function exhibits significant improvement, and no severe complications are observed.

AIM:To investigate the effects and mechanism of Xin-Tong-Tai granule on oxidized low-density li-poprotein(ox-LDL),intercellular adhesion molecule-1(ICAM-1)and vascular cell adhesion molecule-1(VCAM-1)in ApoE-/-mice with atherosclerosis(AS).METHODS:A total of 72 SPF-grade healthy male ApoE-/-mice aged 6～8 weeks were fed with high-fat diet for 12 weeks to replicate AS models,and 12 SPF-grade healthy male C57BL/6J wild mice were fed with ordinary diet as the control group.After the corresponding drugs were administered for 8 weeks,the body weight and general condition of mice in each group were observed.The serum levels of total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C)and low-density lipoprotein cholesterol(LDL-C)were detected by biochemi-cal kits.The pathological structures of aorta were observed by HE and oil red O staining.The levels of serum ox-LDL and aortic ICAM-1 and VCAM-1 were detected by ELISA.The protein levels of NADPH oxidase 4(NOX4),NOX subunit p22phox,inhibitor of κB kinase-α(IKK-α),IKK-β and nuclear factor-κB(NF-κB)in aorta were detected by Western blot.RESULTS:Compared with control group,the mice in model group showed increased body weight(P<0.05),dull and lo-cal shedding hair,slow grasping response,increased serum TC,TG and LDL-C levels,decreased serum HDL-C level(P<0.05),increased the levels of serum ox-LDL and aortic ICAM-1 and VCAM-1(P<0.05),and increased protein expres-sions of NOX4,p22phox,IKK-α,IKK-β and NF-κB in aorta(P<0.05).Compared with model group,the body weight of mice in each treatment group decreased(P<0.05),the hair loss and the response flexibility were also improved.The se-rum levels of TC,TG and LDL-C decreased and HDL-C increased(P<0.05).The levels of serum ox-LDL and aortic ICAM-1(except the low-dose Xin-Tong-Tai granule group)and VCAM-1 decreased(P<0.05).The protein levels of NOX4,p22phox,IKK-α,IKK-β and NF-κB in aorta decreased(P<0.05).HE and oil red O staining showed that typical AS plaques could be seen in blood vessels of the model group,and the red-stained areas were widely distributed.The above lesions were alleviated to different degrees in each treatment group compared with model group.CONCLUSION:Xin-Tong-Tai granule reduces the atherosclerotic plaque area of ApoE-/-mice induced by high-fat diet,decreased serum TC,TG and LDL-C levels,increased HDL-C level,decreased the levels of serum ox-LDL and aorta ICAM-1 and VCAM-1,and inhibited protein expression of NOX4,p22phox,IKK-α and IKK-β in the aorta,thereby attenuating AS.

The aim of this study is to investigate the immune effect of H9 subtype avian influenza virus(AIV)NP protein on mice and lay the foundation for the development of avian influenza vi-rus(AIV)vaccine.The H9N2 virus NP gene amplification product was cloned into the pET-32a expression vector,and the protein expression was verified by SDS-PAGE and Western blot,and the immune effect was evaluated by measuring the secretion of supernatant multicytokines in mouse splenocytes culture.The results showed that the total length of the coding region sequence of NP gene was 1 497 bp,NP recombinant proteins exist in both soluble and insoluble protein forms,and the specific bands were visible in Western blot.After immunizing mice,serum produces IgG-bind-ing antibodies with antibody titers of 1∶40 000.Compared with the control group,IL-2,IL-5 and IL-13 were significantly increased(P＜0.001),and the secretion of IL-6 was significantly increased compared with the control group.IL-4 and IL-12 p70 secretions were elevated compared with con-trols,but there was no significant difference.Compared with the control group,the secretions of IL-1β,IL-18,GM-CMF,TNF-α and IFN-γ were inhibited,but the difference was not significant(P＞0.05).The results showed that NP recombinant protein is a good immunogen,laying a foundation for in-depth research on influenza vaccine.

Objective:To investigate the clinical characteristics, diagnosis and treatment of dermatomyositis with kidney neoplasm.Methods:The data of two patients with dermatomyositis complicated with kidney neoplasm in Tongji Hospital from January to February 2022 were retrospectively analyzed. The first case was a 55-year-old female, who was admitted with the chief complaints of recurrent erythema of upper extremities for 2 months and facial erythema for 1 month. Physical examination: erythema can be seen on upper limbs and face, no tenderness or percussion pain in kidney area. Myositis enzyme profile test showed that anti-Mi-2 antibody and anti-SSA /Ro-52 antibody were positive. Contrast CT showed nodular uneven enhancement in the right kidney with a size of 50 mm×41 mm. The second case was a 58-year-old female, who was admitted with the chief complaints of kidney occupying for a month. Physical examination: flaky erythema on face, no tenderness or percussion pain in kidney area. Myositis enzyme profile test showed that anti-Ro-52 antibody and anti-MDA5 antibody were positive. Contrast CT showed a significantly uneven enhanced mass with a size of about 50 mm×41 mm on left kidney. Both patients were diagnosed with kidney neoplasm before surgery and underwent laparoscopic partial nephrectomy in Tongji Hospital.Results:Both patients received regular oral prednisone after surgery. The pathological presentation of case 1 was papillary renal cell carcinoma, the facial erythema subsided 1 month after surgery, and there was no tumor recurrence for 13 months. The pathological presentation of case 2 was clear cell renal cell carcinoma, facial erythema subsided 2 weeks after surgery, and there was no tumor recurrence for 12 months.Conclusions:The diagnosis of dermatomyositis should be combined with clinical manifestations and laboratory examination, and the possibility of malignant tumor should be excluded due to the high likelihood of concomitant malignancy. For patients with dermatomyositis with kidney neoplasm, the main treatment is still surgery, and supplemented with glucocorticoid therapy.

Objective:Efficacy and safety of robot-assisted laparoscopic adrenalectomy as a treatment for large adrenal tumors.Three-dimensional(3D) reconstruction can effectively assist in preoperative planning of robotic adrenalectomy and reduce potential complications.Methods:We retrospectively reviewed the relevant information of patients who had a preoperative 3D reconstruction and underwent RA for adrenal masses larger than 10 cm. Thirteen male patients and sixteen female patients were included. The median(range) age was 43(25, 57) years old and the median tumor diameter was 12.1(10.3, 16.2) cm. The patients underwent preoperative CT enhancement scanning, and three-dimensional images were reconstructed based on the examination data. Robot-assisted laparoscopic adrenalectomy was performed under general anesthesia in 29 cases in this cohort.Results:All surgeries were completed successfully without major complications such as massive bleeding, secondary surgery, or even patient death. The median operative time was 131 (80, 245) min, and the median intraoperative bleeding was 330 (50, 2 200 ml) ml. 9 patients received blood transfusions. There were 11 cases of pheochromocytoma (37.9%), 10 cases of adenocarcinoma (34.5%) as well as 2 cases of teratoma (6.9%) and 6 cases of cortical carcinoma (20.7%). The patients were followed up for a median of 30 months after surgery. Except for 3 cases lost to follow-up and 2 patients with cortical cancer who developed recurrence or metastasis after surgery and died at 16 and 23 months after surgery, respectively, the remaining 24 cases have survived to date.Conclusions:RA is a safe and effective treatment for huge adrenal tumors. The 3D reconstruction could help the preoperative planning of RA and reduce potential complications.

Objective:To master the 2018 annual oral operation skills assessment of dental standardized residency training trainees, to explore the weak links in the process of the dental residency training, and to provide data support and scientific basis for improving the teaching of clinical skills for dental residency training in the future.Methods:The results of 2018 annual oral operating skills examination of dental standardized residency training trainees in the Affiliated Stomatological Hospital of Nanchang University were collected, the data were sorted by excel and analyzed statistically by SPSS 22.0, and independent sample t test was performed for univariate analysis. Results:The tooth preparation expert results and the scores of cavity preparation expert process in Batch 2017 were higher than those in Batch 2016 [(23.72±2.13) scores vs. (25.82±1.53) scores], and the cavity preparation results of Batch 2017 [(21.08±3.13) scores] were lower than those of Batch 2016 [(23.36±2.32) scores]. The scores of social trainees in the process of tooth preparation [(24.59±2.03) points] were lower than those of the professional postgraduates [(26.29±1.64) points], and the results were all statistically significant ( P<0.05). The three lowest scores of each item in different grades and status types were almost the same. Conclusion:Different grades and different status categories have different scores in different operation items and different score indicators, which suggests that the dental standardized residency training should focus on the weak items and the indicators with lowest scores of each item, so as to make up the shortage and improve the quality of standardized residency training.
