ObjectiveTo explore a procedure to correct the multiple facial deformities by using the expanded frontal flap combined with the axial flaps.MethodsAccording to the face deformity we used the rectangle 100-350 ml expanders behind the frontal hairline,after finishing the tissue expanding,adopted two or three axial flaps based on the supraoribital,supratrochlear or temporal vessels. ResultsA total of 13 cases were treated with this approach.7 eases were nose and lip defect reconstruction after burn,in which temporal vessel-based flap was used in 2 cases and supraoribital or supratrochlear vessel-based flaps in 5 cases.The other 6 cases were nasal reconstruction combined with the frontal defect correction by using random flaps,including 2 cases of pigmented nevus,1 neurofibroma,and 3 burn scars.All the flaps survived and satisfactory appearance was obtained.Conclusions The expanded frontal flap combined with axial flap based on multiple vessels is a good approach to correct the multiple facial deformities.

Objective To investigate the optimal initial timing of Qingyi Decoction and clyster with rhubarb in patients with severe acute pancreatitis (SAP). Methods Patients with SAP were randomly divided into 2 groups. The group A (n = 34) received clyster with rhubarb and Qingyi Decoction after 12 h of SAP onset and the group B (n = 27) received samel therapy after 72 h of onset of SAP. The serum levels of TNF-α, CRP and APACHE Ⅱ scores, time to abdominal pain cessation, length of hospital stay and medical costs were compared. Results The serum levels of TNF-α and CRP of patients in group A were (265±66)U/ml, (32.1 ±7.1) mg/L, and the score of APACHEⅡ were 6. 3±2.0, time to abdominal pain cessation was (4±2) d, length of hospital stay was (18±5)d, medical costs was (42 000±18 000) yuan; while the corresponding values in the group B were (491±81)U/ml, (43.5±11.0) mg/L, 9.1±1.8, (8±3)d, (34±8)d, (71 000±26 000)yuan, and the difference was statistically significantly (P<0.05). Conclusions Qingyi Decoction and clyster with rhubarb should be given in the early phase of SAP in order to achieve better outcomes.

Objective To investigate the clinical efficacy of Bushen Tongdu Capsule for treating patients with rheumatoid arthritis (RA, TCM syndrome of kidney-deficiency with cold). Methods Totally 71 RA patients were randomly divided into treatment group (36 cases) that was treated with Bushen Tongdu Capsule and control group (35 cases) that was treated with tripterygium glycosides tablet. Both groups were treated for 12 weeks. The signs and symptoms, the state of illness, and laboratory index were observed before and after treatment. Results The total effective rate was 72.22% (26/36) in the treatment group, and 62.86% (22/35) in the control group, without statistical significance (P>0.05). After treatment, simplified disease activity index, TCM syndrome integrals, tender joint count, swollen joint count, overall evaluation from patients, overall disease evaluation from doctors, rest pain, morning stiffness time, average hands grip strength, 20 m walking time, healthy condition questionnaire score, and C-reactive protein were significantly improved in both groups (P<0.01, P<0.05). Compared with control group, TCM syndrome integrals changed more significantly, with statistical significance (P <0.05). Conclusion Bushen Tongdu Capsule can relieve symptoms and signs of RA patients (TCM syndrome of kidney-deficiency with cold) effectively.

Objective To reveal the distribution characteristics of serum lipids,lipoproteins,and apolipoproteins levels in different nationalities.Methods Quantitative levels of those traits mentioned above were determined and body height(H),weight(W)and body mass index(BMI=W/H2)were assessed in 773 Kazaks(men 360 and women 413)and 911 Han nationality(men 466 and women 445)from the Xinjiang Autonomous Region of China.Results Kazaks men and women,respectively,had significantly higher serum levels of HDL-c and ApoA1 (all P ＜ 0.001)and significantly lower serum levels of TG(men P ＜ 0.01,women P ＜ 0.001),Lp(a)(allP＜0.005),ApoB(men P＜0.005,women P＜0.001)and ApoB/A1(men P＜0.01,women P＜0.001)than their Han nationality controls.The threshold points of ApoA1(＜ 1.2 g/L)and ApoB(＞ 1.2 g/L)are higher in Hans than in Kazaks for ApoA1(20.7 vs 9.8%)and ApoB(18.6 vs 14.3%);the serum levels of TG,HDL-c,Lp(a),ApoA1 and ApoB/A1 are all closely correlated with nationality(P ＜ 0.001,P = 0.001,and P ＜ 0.05,respectively).Conclusion The results suggest that the nationality differences exist in serum levels of lipids,lipoproteins,and apolipoproteins,and Kazaks have a superior serum lipid pedigree to Hans.This differences may come from genetic differences,which affect the serum levels of lipids,lipoproteins,and apolipoproteins by controlling lipid metabolism pattems.Future study will be needed to dissect to the role of genetic factors on serum lipids.

BACKGROUND: There are significantly interindividual variations of the expression level of nuclear factor erythroid-2-related factor 2 (Nrf2) and/or Kelch-like ECH-associated protein 1 (Keap1) in our previous studies. It has been proven that Nrf2 or Keap1 is related to resistance of chemotherapeutic drugs and/or epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). However, the expression of Nrf2 and Keap1 in lung adenocarcinoma patients with different "driver gene" is not clear. The aim of this study is to investigate the protein expression level of Nrf2 and Keap1 in lung adenocarcinoma and to elucidate the correlation between Nrf2 or Keap1 expression and the status of EGFR gene mutation and to determine the effects of Nrf2 and Keap1 on the patients. METHODS: Immunohistochemical analysis of Nrf2 and Keap1 in tumor specimens was performed in a total of 104 lung adenocarcinoma patients with the status of EGFR gene mutations or EGFR wide-type. RESULTS: The Nrf2 positive rate was 71.2% and Keap1 high expression rate was 34.6% in 104 patients. The Nrf2 positive rate significantly correlated with gender, stage and status of EGFR gene mutation (P<0.05), but not with age, smoking, differentiation and subtype of lung adenocarcinoma (P>0.05). The high expression of Keap1 was not significantly correlated with gender, age, smoking, differentiation, subtype of lung adenocarcinoma and status of EGFR gene mutation (P>0.05). The progression -free survival (PFS) and overall survival (OS) of the patients treated by EGFR-TKIs were significantly correlated with the expression level of Nrf2, but not with Keap1. The PFS and OS of the patients with Nrf2 high expression were significantly shorter than the patients with low/negative expression (P<0.05). Furthermore, Nrf2 high expression was the independent predictive factor for EGFR-TKIs induced PFS and OS (P<0.05). CONCLUSIONS The Nrf2 positive rate significantly correlated with the status of EGFR gene mutation in lung adenocarcinoma. The Nrf2 high expression significantly correlated with PFS and OS of EGFR-TKIs. Therefore, Nrf2 may be a biomarker for predicting response of EGFR-TKIs and a potential target for overcoming resistance of EGFR-TKIs.

【Objective】 To compare the current standards and explore the influencing factors for hemolysis rate of leukocyte-reduced red blood cells at the end of the preservation period, in order to formulate reasonable internal control indicators. 【Methods】 A retrospective analysis was performed on hemolysis rate of 427 samples of leukocyte-reduced red blood cells at the end of the preservation period in Nanning Blood Center from 2015 to 2022. Compared with the current standard for hemolysis rate at the end of the preservation period (GB 18469-2012 Quality Requirements for Whole Blood and Component Blood), the differences were analyzed, and the factors influncing the hemolysis rate were analyzed in terms of different blood donor groups. 【Results】 1) Among the 427 samples, the hemolysis rate of 418 (97.89%) did not exceed 0.4%, all lower than 0.8%; 2)the hemolysis rate of the male group was higher than that of the female group; 3) the hemolysis rate of the 18-29 years old group was lower than that of the 30-39 year old group and the 40-60 year old group, with statistically significant difference; 4) in terms of occupation, the hemolysis rate of students was the lowest, and the differences between groups were statistically significant; 5) no statistical significance was found in ethnicity and blood type. 【Conclusion】 Statistics indicated that gender, age, blood donation volume and occupation of blood donors were the influencing factors of hemolysis rate. The current standard is obviously higher in the qualified range of blood quality control in Nanning. It is advisable to formulate a reasonable quality control strategy with internal control index of hemolysis rate set <0.4%, which is conducive to making accurate evaluation of internal quality control and ensuring blood safety.
