This paper summarizes Professor LIU Fengbin's clinical experience in treating autoimmune liver disease （AILD） using the method of nourishing yin and removing stasis based on stage differentiation. He believes that the pathogenesis of AILD generally involves both deficiency in essence and excess in manifestation， with essence deficiency often presenting as liver and kidney yin deficiency， which may progress to spleen deficiency and yang deficiency over time. The excess manifestation commonly includes qi stagnation， blood stasis， damp-heat， and phlegm toxicity. Clinically， he advocates for the treatment principle of nourishing yin and removing stasis. On the foundation of nourishing liver and kidney yin， different pathological factors causing stasis are eliminated according to their nature. Treatment is also tailored to different stages of AILD. In the early and asymptomatic stages， liver qi stagnation and spleen deficiency are prominent， warranting a therapeutic approach of soothing the liver， regulating qi and strengthening the spleen. The modified Chaishao Qizhi Decoction （柴芍气滞汤） is used. During the symptomatic stage， pathogenic factors become more pronounced， often accompanied by a significant deficiency of vital qi， with damp-heat， water retention， and phlegm toxicity as key pathological features. The treatment should focus on strengthening the spleen and dispelling dampness， using modified Sijunzi Decoction （四君子汤） combined with Yinchen Wuling Powder （茵陈五苓散）. In the liver function decompensation stage， vital qi is severely deficient while pathogenic factors persist， with damp-heat， phlegm toxicity， and blood stasis obstructing the liver collaterals. Treatment should focus on nourishing blood， softening the liver， strengthening the spleen， and resolving stasis， using the modified Ruangan Yangxue Decoction （软肝养血汤）. Throughout the treatment process， emphasis is placed on tonifying the liver and kidneys while protecting yin fluids.

Wound infection is becoming a considerable healthcare crisis due to the abuse of antibiotics and the substantial production of multidrug-resistant bacteria. Seawater immersion wounds usually become a mortal trouble because of the infection of Vibrio vulnificus. Bdellovibrio bacteriovorus, one kind of natural predatory bacteria, is recognized as a promising biological therapy against intractable bacteria. Here, we prepared a B. bacteriovorus-loaded polyvinyl alcohol/alginate hydrogel for the topical treatment of the seawater immersion wounds infected by V. vulnificus. The B. bacteriovorus-loaded hydrogel (BG) owned highly microporous structures with the mean pore size of 90 μm, improving the rapid release of B. bacteriovorus from BG when contacting the aqueous surroundings. BG showed high biosafety with no L929 cell toxicity or hemolysis. More importantly, BG exhibited excellent in vitro anti-V. vulnificus effect. The highly effective infected wound treatment effect of BG was evaluated on mouse models, revealing significant reduction of local V. vulnificus, accelerated wound contraction, and alleviated inflammation. Besides the high bacterial inhibition of BG, BG remarkably reduced inflammatory response, promoted collagen deposition, neovascularization and re-epithelization, contributing to wound healing. BG is a promising topical biological formulation against infected wounds.

Objective:To compare the clinical effects robot navigation assisted and conventional proximal femoral nail antirotation (PFNA) implantation and fixation in the treatment of elderly femoral trochanteric fractures.Methods:A total of 86 elderly patients with tuberosity fracture of the femur were admitted as research samples from January to March in 2022 in the Department of Trauma Orthopaedic, Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University, including 37 males and 49 females, who aged from 63 to 92 years, with an average age of (79.6 ± 6.9) years. All patients were treated with intramedullary nails (PFNA), 32 with dimensity robotic-assisted therapy (robot group) and 54 with traditional methods (conventional group). The length of incision, the number of intraoperative fluoroscopy, the amount of intraoperative blood loss, and the operation time were recorded. The occurrence of postoperative complications in the two groups was observed. The rate of excellent hip Harris score at 3 month after surgery was compared between the two groups. Measurement data with normal distribution were represented as mean ± standard deviation( ± s), and the comparison between groups was conducted using the t-test; the comparison of count data were represented as [ n(%)], and was conducted by Chi-square test or Fisher exact probability between groups. Results:All patients were followed up for 9 to 12 months, with an average of (10.6 ± 0.9) months. The incision length and tip apex distance (TAD) of the robot group were (3.40±0.82) cm and (21.85±1.44) mm, which were smaller than (4.82±0.75) cm and (26.83±1.75) mm in the conventional group ( P<0.05 for all). The number of intraoperative fluoroscopy and guide needle adjustment [(14.53±3.26) and 0 times] in the robot group were less than those in the conventional group [(20.67±4.84) and (2.83±1.42)] ( P<0.05). The intraoperative blood loss and drainage rate of the robot group were (87.03±9.41) and (46.40±8.91) mL, which were smaller than that of the conventional group [(110.00±12.52) and (69.62±10.22) mL] ( P<0.05). There was no significant difference in the number of days of hospitalization and operation time between the two groups ( P>0.05). The postoperative complication rate in the robot group was 9.4%, which was lower than that in conventional group (42.6%), and the difference was statistically significant ( χ2=11.88, P=0.036). The excellent rate of postoperative hip joint function in the robot group was 75.0%, and the conventional group was 66.7%, and there was no significant difference between the two groups ( χ2=0.66, P=0.416). Conclusion:Robot-assisted navigation downward PFNA surgery can have good clinical effect in the treatment of femoral tuberosity fracture in the elderly, which can reduce the number of surgical incisions and intraoperative fluoroscopy, and reduce the incidence of postoperative complications, which is helpful to achieve minimally invasive surgery and rapid recovery of elderly patients with femoral tuberosity fracture.

Objective:To investigate the effect of galactose lectin 3 (Gal-3) on the pathogenesis of atrial fibrillation.Methods:This study adopts a case-control study method. 55 patients with non valvular atrial fibrillation (atrial fibrillation group) admitted to the First People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from February to July 2019 were selected, and another 55 healthy individuals who underwent physical examination at our hospital during the same period were selected as the control group. Compare the general data and levels of various laboratory indicators between two groups, including blood routine, fasting blood glucose, blood lipids, liver and kidney function, and plasma Gal-3. Analyze the influencing factors of atrial fibrillation and the predictive value of plasma Gal-3 levels for the onset of atrial fibrillation. The measurement data with normal distribution and the measurement data converted to normal distribution after taking natural logarithm are expressed in xˉ± s. The comparison between the two groups is performed by independent sample t test; The measurement data of non normal distribution is represented by [ M ( Q1, Q3)], and Wilcoxon signed rank sum test is used for inter group comparison; The counting data is represented by examples (%), and the comparison between groups is conducted using χ 2 test. The influencing factors of atrial fibrillation were analyzed using logistic regression analysis. Results:The age, NLR, and blood creatinine levels in the atrial fibrillation group were higher than those in the control group [(71.16±9.17) years vs (60.71±10.11) years, (2.32±0.85) vs (1.74±0.81), (74.18±21.61) μmol/L vs (64.69±18.30) μmol/L, t-values are 5.68, 3.66, 2.48, P-values are <0.001, <0.001, 0.015], total cholesterol, HDL-C, LDL-C Albumin and eGFR water were on average lower than those in the control group [(4.31±1.67) mmol/L vs (5.13±0.78) mmol/L, (0.96±0.21) mmol/L vs (1.21±0.32) mmol/L, (2.35±0.65) mmol/L vs (3.04±0.62) mmol/L, (39.58±3.83) g/L vs (44.66±5.61) g/L, (94.84±29.22) mL/(min·1.73 m 2) vs (111.77±21.51) mL/(min·1.73 m 2)] ,The t-values are 3.30, 4.87, 5.69, 5.54, 3.46, and the P-values are 0.001,<0.001,<0.001,<0.001, 0.001, respectively. The plasma Gal-3 levels in the atrial fibrillation group were higher than those in the control group [(12.79±4.24)] μg/L vs (7.31±2.28) μg/L], the difference was statistically significant ( t=8.43, P<0.001), and the plasma Gal-3 level in the persistent atrial fibrillation group was higher than that in the paroxysmal atrial fibrillation group [(14.03±3.95) μg/L vs (11.51±4.21) μg/L], the difference was statistically significant ( t=2.29, P=0.026). The results of multivariate logistic regression analysis showed that after excluding other factors, Gal-3 remained an independent influencing factor for atrial fibrillation (odds ratio=1.66, 95% confidence interval: 1.29-2.12, P<0.001). Conclusions:Plasma Gal-3 is an influencing factor for the onset of atrial fibrillation. After excluding other factors, Gal-3 remains an independent influencing factor for atrial fibrillation, with an increase of 1 μg/L in Gal-3 increases the risk of atrial fibrillation by 1.66 times.

Radiation therapy is an effective method to kill cancer cells and shrink tumors using high-energy X-ray or γ-ray. Radiation pneumonitis (RP) is one of the most serious complications of radiation therapy for thoracic cancers, commonly leading to serious respiratory distress and poor prognosis. Here, we prepared curcumin-loaded mesoporous polydopamine nanoparticles (CMPN) for prevention and treatment of RP by pulmonary delivery. Mesoporous polydopamine nanoparticles (MPDA) were successfully synthesized with an emulsion-induced interface polymerization method and curcumin was loaded in MPDA via π‒π stacking and hydrogen bonding interaction. MPDA owned the uniform spherical morphology with numerous mesopores that disappeared after loading curcumin. More than 80% curcumin released from CMPN in 6 h and mesopores recovered. CMPN remarkably protected BEAS-2B cells from γ-ray radiation injury by inhibiting apoptosis. RP rat models were established after a single dose of 15 Gy ⁶⁰Co γ-ray radiation was performed on the chest area. Effective therapy of RP was achieved by intratracheal administration of CMPN due to free radical scavenging and anti-oxidation ability, and reduced proinflammatory cytokines, high superoxide dismutase, decreased malondialdehyde, and alleviated lung tissue damages were observed. Inhaled CMPN paves a new avenue for the treatment of RP.

Objective:To analyze the current status of frailty in elderly patients undergoing cardiac surgery, explore its risk factors, and establish a predictive model of frailty in order to provide targeted and predictive nursing programs.Methods:A total of 205 cardiac surgery patients admitted to the first affiliated hospital of Xinjiang Medical University from March 2015 to January 2019 were selected as the study subjects. Patients were divided into 2 groups according to whether they were frail: the frailty group ( n=78) and the control group ( n=127). Logistic regression was used to analyze the risk factors that affect the frailty of elderly patients undergoing cardiac surgery. The receiver operating characteristic curve (ROC) was used to evaluate the effectiveness of model X [consisting of body mass index (BMI), Mini-Mental State Examination (MMSE) score, number of diseased patients, and number of drugs] in diagnosing frailty in elderly patients undergoing cardiac surgery. Results:Of the 205 patients, 78 (38.05%) showed frailty. The proportion of high school education level and above, Tinetti Gaitassessment (TGA) score≥24 and MMSE score≥27 in the frailty group was lower than that in the control group, and the proportion of Geriatric Depression Scale-15 (GDS-15) score≥7, the number of diseases≥3 and the number of drugs≥5 in the frailty group was higher than that in the control group ( χ2 value was 9.254-26.061, P<0.05). Logistic regression analysis showed that BMI, MMSE score, number of diseased, and number of medications were independent risk factors for frailty in elderly patients undergoing cardiac surgery ( OR value was 0.032-5.275, P<0.05). The area under the ROC curve, sensitivity and specificity of frailty in elderly cardiac surgery patients assessed by model X were 0.913, 75.61% and 96.77%, respectively. Conclusion:The incidence of frailty is higher in elderly patients undergoing cardiac surgery. Model X can diagnose the frailty of elderly patients undergoing cardiac surgery and help clinical nurses to carry out targeted care.

Objective Focused cardiac ultrasound (FCU) and lung ultrasound (LU) are increasingly being used in critically ill patients. This study aimed to investigate the effect of FCU in combination with LU on these patients and to determine if the timing of ultrasound examination was associated with treatment change. Methods This is a multicenter cross-sectional observational study. Consecutive patients admitted to the intensive care unit (ICU) were screened for enrollment. FCU and LU were performed within the first 24 h, and treatment change was proposed by the performer based on the ultrasound results and other clinical conditions. Results Among the 992 patients included, 502 were examined within 6 h of ICU admission (early phase group), and 490 were examined after 6 h of admission (later phase group). The early phase group and the later phase group had similar proportions of treatment change (48.8%

Objective To analyze the early outcomes of 203 neonates with low birth weight (<2 500 g) undergoing cardiac surgery, and to analyze the causes of death during hospitalization. Methods From June 2003 to June 2017, medical records of 203 neonates with low birth weight undergoing congenital heart surgery in Guangdong General Hospital were reviewed retrospectively. There were 124 males and 79 females, including 151 premature infants. The average birth weight was 1 719±515 g, the average age at operation was 32.7±20.2 d and the average weight at operation was 1 994±486 g. The causes of death during hospitalization (including neonates given up on treatments) were analyzed. Results Totally 103 patients had pneumonia, 98 patients needed mechanical ventilation to support breathing and 26 patients needed emergency operation before operation. All patients undergoing congenital heart surgery were treated with general anesthesia with tracheal intubation, including 107 patients under non cardiopulmonary bypass (CPB) and 96 patients under CPB with a mean CPB time of 96.5±71.7 min and a mean aorta cross-clamp time of 51.8±45.5 min. The average postoperative mechanical ventilation time was 9.1±21.5 d and the average postoperative length of stay was 26.7±19.3 d. The major postoperative complications included pneumonia, anemia, atelectasis, septicemia, intrapleural hemorrhage, diaphragm paralysis and cardiac dysfunction. Twenty-nine patients died during hospitalization and the overall mortality rate was 14.3%. Four patients died in the operation room, 14 patients died 72 hours after operation and 2 patients were given up. The main causes of hospitalized death were low cardiac output syndrome, severe infection, disseminated intravascular coagulation disorder, acute renal failure and pulmonary hypertension crisis. Conclusion Overall, early cardiac surgery for low birth weight neonates is safe and effective. The difficulty of the cardiac surgery is the key to the prognosis. Strengthening perioperative management can improve the quality of operation and reduce the risk of mortality and morbidity during hospitalization.

Clinical data of 153 patients with multiple myeloma admitted from January 2005 to December 2015 were retrospectively reviewed,including 56 cases complicated with herpes zoster (case group) and 97 cases without herpes zoster (control group).The risk factors for herpes zoster in multiple myeloma patients were analyzed by univariate and multivariate logistic regression.Univariate analysis showed that herpes zoster significantly associated with albumin/globulin ratio (A/G) ＜ 0.5 (x2 =10.989,P ＜0.05),unremitted myeloma(x2 =12.310,P ＜ 0.05),neutropenia (x2 =8.100,P ＜ 0.05) and treatment with bortezomib(x2 =9.465,P ＜ 0.05).Multivariate logistic regression analysis showed that herpes zoster was positively correlated with A/G ＜ 0.5 (OR =6.344,95％ CI:1.511-26.645,P ＜ 0.05),neutropenia (OR =6.402,95％ CI:1.420-28.869,P ＜ 0.05),treatment with bortezomib (OR =7.335,95％ CI:1.587-33.911,P ＜ 0.05);and negatively correlated with remitted myeloma (OR =0.064,95％ CI:0.017-0.237,P ＜ 0.05).It is necessary to take corresponding countermeasures targeting the risk factors to prevent herpes zoster in multiple myeloma patients.
