This paper summarized the experience in treating flat warts by Professor XU Xian based on the theory of Bai Qi （白气） micro-discharge. Flat warts is considered as a minor skin disease. Wind-damp attacking the exterior and contention between the muscles are the prerequisites for its occurrence， and failure to diffuse due to wei （卫） constraint， and qi discharge to striae and interstices are the core pathogenesis. For treatment， the core principle is to treat minor diseases with minor adjustment， and therefore， the method of dispelling wind and overcoming dampness is used to produce slight sweating and relieve the symptoms， and by taking advantage of the situation， the constraint is unblocked with diffusion and dispersion. Simultaneously， it is paid attention to not over-damaging blood vessels during treatment to avoid causing other symptoms. Self-made Modified Maxing Yigan Decoction （麻杏薏甘汤） is recommended as the basic formula for flat warts， together with self-made Xi You Formula （洗疣方） in external administration to restore defense qi， eliminate pathogenic qi and remove the warts.

Objective:To standardize the management of auditory hallucination symptoms in inpatients with mental illness and develop an expert consensus on the management of auditory hallucinations in hospitalized psychiatric patients.Methods:From March 2023 to July 2023, the Mental Health Committee of the Chinese Nursing Association focused on the key issues in the management of auditory hallucinations symptoms in inpatients with mental illness, based on clinical practice, using literature analysis combined with the work experience of mental health experts, and formed the first draft of the expert consensus on the management of auditory hallucinations in inpatients with mental illness (hereinafter referred to as the consensus). Through 3 rounds of expert consultation and 3 rounds of expert demonstration meeting, the draft was adjusted, revised, and improved.Results:37 experts were included in the Delphi expert consultation, 1 male and 36 females with 39-67(51.48 ± 6.61) years old. The positive coefficients of experts in 3 rounds of Delphi expert consultations were all 100%, and the degrees of expert authority were 0.924, 0.938 and 0.949, respectively. The average importance value of each item was higher than 4.00, the variation coefficient of each item was less than 0.25. The Kendall harmony coefficient of the experts were 0.179, 0.195 and 0.198, respectively (all P<0.05). There were 15, 12, 12 experts in the first, seeond, third rounds of expert demonstration meeting. Finally, a consensus was reached on the recommendation of 4 parts, included auditory hallucination assessment, management format, symptom management implementation, and precautions. Conclusions:The consensus covers all parts of the management of auditory hallucination symptoms in hospitalized patients with mental disorders, which is practical and scientific. It is helpful to guide mental health professionals to standardize the management of auditory hallucination symptoms, improve the quality of nursing and ensure the safety of patients.

Damage to organelles plays a significant role in myocardial ischemia/reperfusion injury,which results in the dysfunction of mitochondria and other related organelles.The communication between mitochondria and other organ-elles can also affect the development of myocardial ischemia/reperfusion injury.For instance,the mitochondria-associated endoplasmic reticulum membrane provides a"seamless connection"and regulates the exchange of organelles and metabolites(such as ions,lipids and proteins)between the mitochondria and the endoplasmic reticulum,which subse-quently affects myocardial ischemia/reperfusion injury.However,there is a lack of studies regarding the interaction be-tween mitochondria and related organelles,which is a critical component in triggering myocardial ischemia/reperfusion inju-ry.Therefore,this article describes the role of mitochondrial crosstalk with endoplasmic reticulum,lysosomes and nuclei in myocardial ischemia/reperfusion injury,and aims to provide a theoretical basis for targeting mitochondrial crosstalk with other organelles in the treatment of myocardial ischemia/reperfusion injury.

This article summarized Professor Zhu Renkang's experience in treating chronic eczema with Ziyin Chushi Decoction.Professor Zhu Renkang believes that eczema's onset is inseparable from pathogenic dampness.Pathogenic dampness runs through all stages of the disease.Stage of attack is dominated by excessive pathogen.Pathogenic wind attacks the exterior,while the muscular interstices is not dense,which makes nutritive yin leak out and stagnate as pathogenic dampness,then wind and dampness combined with each other.Chronic stage is dominated by yin deficiency.Long-term illness damages healthy qi,and pathogenic dampness conceals in the body,which makes deficiency of nutritive yin inside and dryness outside.Professor Zhu Renkang focuses on the characteristics of chronic eczema characterized by deficiency of yin and retention of dampness pathogens.He establishes Ziyin Chushi Decoction,and emphasizes that nutritive yin and pathogenic dampness have the same origin but different paths and can exist simultaneously.The combined utilization of nourishing yin and eliminating dampness can restore yin without helping dampness,remove dampness without harming yin,which have achieved satisfactory efficacy.

Inducing the degradation of KRAS represents a novel strategy to combat cancers with KRAS mutation. In this study, we identify ubiquitin-specific protease 2 (USP2) as a novel deubiquitinating enzyme of KRAS in multiple myeloma (MM). Specifically, we demonstrate that gambogic acid (GA) forms a covalent bond with the cysteine 284 residue of USP2 through an allosteric pocket, inhibiting its deubiquitinating activity. Inactivation or knockdown of USP2 leads to the degradation of KRAS, resulting in the suppression of MM cell proliferation in vitro and in vivo. Conversely, overexpressing USP2 stabilizes KRAS and partially abrogates GA-induced apoptosis in MM cells. Furthermore, elevated USP2 levels may be associated with poorer prognoses in MM patients. These findings highlight the potential of the USP2/KRAS axis as a therapeutic target in MM, suggesting that strategically inducing KRAS degradation via USP2 inhibition could be a promising approach for treating cancers with KRAS mutations.

Objective:To investigate the effect of ultrasound-guided lumbar quadratus muscle plane block combined with general anesthesia on the analgesic effect during and after laparoscopic colon cancer radical surgery in elderly patients.Methods:A prospective study was conducted on 61 elderly patients who underwent radical colon cancer surgery at the Changsha Central Hospital Affiliated to South China University from May 2022 to February 2023, with American Society of Anesthesiologist (ASA) grades Ⅱ to Ⅲ. They were randomly divided into SA and GA groups using a random number table method, with 31 patients in the SA group and 30 patients in the GA group. The SA group received ultrasound-guided plane block of the upper lumbar quadratus muscle in the arcuate ligament combined with general anesthesia, while the GA group received simple general anesthesia. Record the mean artery pressure (MAP) and heart rate (HR) of two groups of patients at the time of entering the operating room (T 0), 5 minutes before skin incision (T 1), at skin incision (T 2), 30 minutes after surgery (T 3), at surgery end (T 4), and during anesthesia resuscitation and extubation (T 5); The Visual Analogue Scale (VAS) of two groups of patients at T 5, upon returning to the ward (T 6), 6 hours (T 7), 12 hours (T 8), 24 hours (T 9), and 48 hours (T 10) after surgery were recorded; The dosage of sufentanil, remifentanil, and propofol used during surgery, anesthesia recovery time, total number of analgesic pump presses within 48 hours after surgery, Lovett muscle strength score, early postoperative recovery, and adverse reactions within 48 hours after surgery were also recorded. Resultsl:The MAP and HR of the SA group were lower than those of the GA group at T 1-5 (all P<0.05); The VAS score of the SA group was lower than that of the GA group at T 5-10 (all P<0.05); The intraoperative dosage of propofol, remifentanil, and sufentanil in the SA group was lower than that in the GA group (all P<0.05); The anesthesia recovery time and first time out of bed in the SA group were earlier than those in the GA group (all P<0.05); The total number of times the analgesic pump was pressed within 48 hours after surgery was less than that of the GA group ( P<0.05); The incidence of nausea and vomiting within 48 hours after surgery in the SA group was lower than that in the GA group ( P<0.05). There was no statistically significant difference in postoperative Lovett muscle strength score, hospital stay, and dizziness incidence between the two groups of patients (all P>0.05). Conclusions:Ultrasound-guided lumbar quadratus muscle plane block on the arcuate ligament can significantly reduce the dosage of intraoperative general anesthesia drugs and postoperative analgesics in elderly patients undergoing laparoscopic colon cancer surgery, reduce postoperative pain scores, effectively alleviate postoperative pain, and thus advance the patient′s first time out of bed activity, reduce postoperative complications, and promote rapid recovery.

Objective:To retrospective analyze the epidemiology, clinical characteristics, treatment and prognosis in patients with coronavirus disease 2019 (COVID-19).Methods:A total of 278 patients with COVID-19 admitted to Guangzhou Eighth People′s Hospital from January 20 to February 10, 2020 were selected. The general demographic data, epidemiological data, clinical symptoms, laboratory examinations, lung CT imaging, treatment and prognosis were analyzed.Results:There were 130 male patients (46.8%) and 148 females (53.2%) with age (48.1±17.0) years and 88.8% patients between 20-69 years. Two hundred and thirty-six (84.9%) patients had comorbidities. Two hundred and eleven cases (75.9%) were common type. The in-hospital mortality was 0.4% (1/278). The majority (201, 72.3%) were imported cases mainly from Wuhan (89, 44.3%). The most common clinical manifestations were fever (70.9%) and dry cough (61.5%). In some patients, hemoglobin (10.4%), platelets (12.6%) and albumin (55.4%) were lower than the normal range. Other biochemical tests according to liver and function were normal, while lactic dehydrogenase (LDH) was elevated in 61 patients (21.9%), creatine kinase increased in 26 patients (9.4%). Prolonged activated partial thromboplastin time (APTT) was seen in 52 patients (18.7%), D-dimer higher than normal in 140 patients (50.4%), while 117 patients (42.1%) had elevated high-sensitivity C-reactive protein. Typical CT manifestations included single or multiple ground glass shadows especially in lung periphery in early disease which infiltrated and enlarged during progressive stage. Diffuse consolidation with multiple patchy density in severe/critical cases and even "white lung" presented in a few patients. Two hundred and forty-two patients (87.1%) received one or more antiviral agents, 242 (87.1%) combined with antibacterials, 191 (68.7%) with oxygen therapy. There were 198 patients (71.2%) treated with traditional Chinese medicine.Conclusions:COVID-19 could attack patients in all ages with majority of common type and low mortality rate. Clinical manifestations involve multiple organs or systems. Progression of the disease results in critical status which should be paid much attention.

Objective:To explore the relationship between death indicators and unplanned return indicators on healthcare quality evaluation.Methods:A total of 836 976 medical record data were collected from 31 tertiary public general hospitals in a diagnosis-related groups(DRG) data platform in 2017. Multiple death indices(low and low-risk risk group mortality, high-risk group mortality, crude mortality, and risk adjusted mortality) and unplanned return indices(31-day unplanned readmission rate and 31-day unplanned return to surgery rate) were calculated. Pearson′s correlation coefficient was used to examine the relationships among those indices.Results:Death indicators were correlated with each other, but the unplanned readmission rate was not correlated with the unplanned reoperation rate( r=0.305). There was no correlation between unplanned re-entry rate and death rate. The correlation coefficients were as follows: unplanned readmission rate versus low and low-risk group mortality( r=-0.227), versus high-risk group mortality( r=-0.098), versus actual mortality( r=-0.130), versus risk adjusted mortality( r=0.010); unplanned reoperation rate versus low and low-risk group mortality( r=0.105), versus high-risk group mortality( r=0.030), versus actual mortality( r=-0.004), versus risk adjusted mortality( r=-0.141). Conclusions:The indicators of death and the indicators of unplanned return are not the same in terms of actual management technology and evaluation effect. They are complementary to each other and can form an ideal combination of quality evaluation indicators.

Objective:To explore the influencing factors of 31-day unplanned readmission in obstetrics.Methods:The medical records and relevant clinical data of 29 public hospitals in a province in 2017 were collected to construct a two-level logistic regression model on the influencing factors of 31-day unplanned readmission.Results:In 2017, there were 71 330 obstetric patients discharged from 29 public hospitals, 690 of whom were unplanned readmitted in 31 days, accounting for 0.97%. The type of medical insurance payment, number of previous hospitalization, condition of previous hospitalization, age, history of cesarean section, pregnancy complications and complications during delivery were all the factors influencing the 31-day unplanned readmission of obstetrics.Conclusions:The condition of 31-day unplanned readmission could be influenced by the factors of sociology, previous visit and clinical. These factors should be considered reasonably in the evaluation and management of obstetric quality.

Objective: To analyze the significance of serum free light chain (sFLC) for the prognosis of the patients with newly diagnosed multiple myeloma (NDMM). Methods: The clinical data of 621 NDMM patients in Changzheng Hospital from June 2010 to December 2016 was retrospectively analyzed. The serum free light chain levels were measured and the ratios of κ/λ chains were calculated. The significance of serum free light chain ratio (sFLCR) for the prognosis of NDMM patients was analyzed. Results: Among the 621 NDMM patients, 42 patients (6.8%) were in the normal free light chain ratio group (0.26≤sFLCR≤1.65), 247 patients (39.8%) were in the low free light chain ratio group (0.01＜sFLCR＜0.26 or 1.65＜sFLCR＜100), and 332 patients (53.5%) were in the high free light chain ratio group (sFLCR≤0.01 or sFLCR≥100). Compared with normal sFLCR group, the abnormal sFLCR group showed low level of hemoglobin; elevated levels of bone marrow plasma cells, serum creatinine and β 2 -MG, and more patients were in DS stage Ⅲ and ISS stage Ⅲ with high risks of cytogenetics(all P＜0.05). The overall survival (OS) in the normal sFLCR group was significantly better than the abnormol sFLCR groups (not reached vs 58.7 months, P=0.043). Compared with the patients with both high sFLCR and low risks of cytogenetics, the patients with high sFLCR and high risks of cytogenetics showed shorter overall survival time (median OS time was 41.6 months vs 61.4 months, P=0.015). Conclusion The NDMM patients with significantly abnormal sFLCR may indicate more tumor load and higher aggressive progression. sFLCR should be an independent prognostic indicator for the outcome of multiple myeloma. The patients with high sFLCR and cytogenetic abnormalities, have worse prognosis than the others.
