Combining the knowledge of traditional Chinese medicine and modern medicine on glucolipid metabolism disorders， it is believed that the formation process of glycolipid metabolism disorders can be presented as five states "depression， phlegm-dampness， heat， blood stasis， and deficiency"， and the turbid pathogens run through the whole process. Accordingly， the method of "regulating states and removing turbidity" is proposed， which is specifically the method of resolving depression and turbidity， dispelling phlegm-dampness and turbidity， clearing heat and turbidity， dispelling blood stasis and turbidity， and replenishing deficiency and removing turbidity. Combined with the biological basis of glycolipid metabolism disorder， through the analysis of the clinical application of each method and the related mechanism of action， it is clarified that the method of regulating states and resolving turbidity can play a role in improving glycolipid metabolism disorder by regulating lipid metabolism disorder， insulin resistance， bile acid metabolism abnormality， intestinal bacterial flora， and its metabolite abnormality and other mechanisms of action.

Objective:To investigate the effect and mechanism of the V-set and immunoglobulin domain-containing 4 ( VSIG4 ) gene mutation on the function of microglia in retinitis pigmentosa (RP). Methods:Localization of VSIG4 in the retina was detected by immunofluorescence.HMC3 cells (human microglial cells) were transfected with wild-type (Len-WT) VSIG4 gene, mutant type (Len-Mut) VSIG4 gene and empty vector virus (Len-Cont) and stimulated by the presence or absence of lipopolysaccharide (LPS), then divided into control group, LPS-Len-Mut group, LPS-Len-WT group, LPS-Len-Cont group, Len-Mut group, Len-WT group and Len-Cont group.The mRNA expression levels of the inflammatory factors interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were detected by real-time fluorescence quantitative PCR.Protein expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase 1 (HO-1), glutathione peroxidase 4 (GPX4), nuclear transcription factor-κB (NF-κB) p65 subunit (P65), and phosphorylated P65 (PP65) were detected by Western blot.Cell phagocytic function was detected by phagocytosis assay.Cell migration ability was detected by cell scratch and transwell migration assay.LPS- stimulated HMC3 cells were co-cultured with 661W cells (mouse retinal photoreceptor cells), and the expression levels of B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X (Bax) proteins of the cells were detected by Western blot.The number of apoptotic cells was determined by apoptosis assay. Results:VSIG4 was localized to microglia in mouse retina.The real-time fluorescence quantitative PCR results showed that compared with LPS-Len-WT group, the relative expression levels of IL-1β and TNF-α mRNA in HMC3 cells were significantly increased in LPS-Len-Mut group (both at P<0.05).The Western blot results showed that compared with LPS- Len-WT group, the protein expression levels of Nrf2, HO-1, and GPX4 in HMC3 cells were significantly reduced in LPS-Len-Mut group, and the PP65/P65 ratio was significantly increased (all at P<0.05).The phagocytic experiment results showed that the phagocytic rates of HMC3 cells in Len-Cont group, LPS-Len-Cont group, LPS-Len-WT group, and LPS-Len-Mut group were (35.67±3.22)%, (63.67±10.07)%, (84.00±3.46)%, and (64.67±2.31)%, respectively, showing a statistically significant difference ( F=59.06, P<0.001).Compared with LPS-Len-WT group, the phagocytic rate of HMC3 cells was significantly reduced in LPS-Len-Mut group ( P<0.05).The results of cell scratch and transwell migration assay showed that compared with LPS-Len-WT group, the migration rate of HMC3 cells at 24 and 48 hours and the number of invading cells per unit area at 24 hours were significantly reduced in LPS-Len-Mut group (all at P<0.05).Compared with LPS-Len-WT group, the expression ratio of Bax/Bcl-2 protein and the number of cell apoptosis were significantly increased in the LPS-Len-Mut group under the co-culture system (both at P<0.05). Conclusions:VSIG4 is localized to mouse retinal microglia.When the VSIG4 gene in RP mutates, HMC3 cells under LPS stimulation exhibit a series of changes, including activation of the NF-κB signaling pathway, decreased activation of the Nrf2/HO-1 signaling pathway, increased secretion of inflammatory cytokines, reduced phagocytic and migratory abilities, and increased cell apoptosis in co-culture systems.

Objective:To explore the expression and clinical significance of ASB6 in colorectal cancer tissue.Methods:The cancer tissues and para-carcinoma tissues were selected from 106 patients with colorectal cancer admitted to the Department of Gastrointestinal Surgery, Third Affiliated Hospital of Shandong First Medical University from January 2015 to January 2018. Immunohistochemical method was used to detect the expression level of ASB6 protein in tissues, and the correlation between its expression and clinical pathological characteristics of patients was analyzed. At the same time, the expression of ASB6 mRNA in colorectal cancer tissues and para-carcinoma tissues was detected by quantitative real-time PCR (qRT-PCR). The Kaplan-Meier survival analysis method was used to explore the relationship between the expression of ASB6 and prognosis in colorectal cancer patients. The Cox regression model was used to analyze the independent prognostic factors of colorectal cancer patients.Results:The high expression rate of ASB6 in colorectal cancer tissues (67.9%, 72/106) was significantly higher than that in para-carcinoma tissues (10.4%, 11/106, χ2=73.67, P<0.001). Further analysis showed that the expression of ASB6 protein was significantly correlated with lymph node metastasis ( χ2=7.34, P=0.007) and TNM stage ( χ2=16.85, P<0.001). There was no significant correlation between the expression of ASB6 protein and age ( χ2=0.42, P=0.516), sex ( χ2=0.76, P=0.385), tumor size ( χ2=0.91, P=0.341), tumor location ( χ2=2.29, P=0.130), histological classification ( χ2<0.01, P>0.999), differentiation degree ( χ2=2.54, P=0.111) and distant metastasis ( χ2=3.38, P=0.066). qRT-PCR results showed that the expression level of ASB6 mRNA in colorectal cancer tissues was significantly higher than that in para-carcinoma tissues (5.37±0.13 vs. 3.39±0.09, t=-12.48, P<0.001). Kaplan-Meier survival analysis showed that the overall 5-year survival rates of patients in the ASB6 high expression group (72 cases) and the ASB6 low expression group (34 cases) were 45.8% and 73.5%, respectively ( χ2=6.82, P=0.009). Univariate survival analysis found that ASB6 protein expression ( HR=3.09, 95% CI: 1.25-7.65, P=0.015), lymph node metastasis ( HR=0.41, 95% CI: 0.21-0.82, P=0.011), distant metastasis ( HR=0.20, 95% CI: 0.10-0.42, P<0.001), and TNM stage ( HR=0.10, 95% CI: 0.03-0.32, P<0.001) were prognostic factors, while multivariate Cox survival analysis found that distant metastasis ( HR=0.22, 95% CI: 0.09-0.50, P<0.001) and TNM stage ( HR=0.25, 95% CI: 0.11-0.58, P<0.001) were independent prognostic factors. Conclusion:The expression of ASB6 in colorectal cancer tissues is significantly higher than that in para-carcinoma tissues, and the prognosis of patients with high expression of ASB6 is significantly worse than that of patients with low expression of ASB6. ASB6 can be used as an important indicator for early monitoring and postoperative survival assessment of colorectal cancer patients in the future.

The clinical data of patients with chlamydia psitsiti pneumonia confirmed by metagenomic next-generation sequencing (mNGS) who were admitted to the Huizhou Municipal Central Hospital from January 2020 to November 2021 were retrospectively analyzed. Among 21 patients, the serum creatine kinase (CK) was elevated in 10 cases, and 5 cases was complicated with rhabdomyolysis (RM). The symptoms of patients with Chlamydia psittaci pneumonia-induced RM were severe, including high fever, dyspnoea, headache and myalgia; 2 case were complicated by acute kidney injury (AKI) and neurological symptoms. Laboratory testing showed a marked increase in CK, myoglobin (Mb), high sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6) and D-dimer levels in all 5 patients. The chest CT revealed large areas of pulmonary consolidation, ground-glass opacity in 1 case and a small amount of pleural effusion in 2 cases. One patient died from multiple organ failure, and the other 4 patients were discharged with considerable improvement. Patients with psittacosis pneumonia are prone to developing rhabdomyolysis, early detection and early treatment can effectively improve the prognosis of patients.

Medical ethics has a long history and rich connotations.It has developed from the simple "medical morality" of ancient times to the modem medical ethics.The basic principles of medical ethics include autonomy,non-maleficence,beneficence,justice,and so on.Researchers often conduct clinical researches in the balance between achievements and ethical norms.Clinical researchers of surgery should have a deep understanding of medical ethical principles and strictly abide by medical ethics.Ethics committee should strictly perform their duties and play the role of inspection and supervision.Modem medical knowledges should be popularized throughout the society to make clinical research correctly understood.Adhering principles of ethics first,people orientation and cooperation practice,with patients' benefit as evaluation criteria,balance of surgical "Dao" and "Shu" can be achieved.

Objective: To investigate the effects of stage Ⅰ opening and stage Ⅱ opening of prophylactic ileostomy on postoperative recovery in low rectal cancer. Methods: The prospective study was conducted. The clinical data of 88 patients with low rectal cancer who underwent laparoscopic rectal resection and prophylactic terminal ileostomy in the Affiliated Hospital of Qingdao University from September 2016 to May 2017 were collected. According to random number table, patients undergoing laparoscopic rectal resection combined with prophylactic ileostomy with stage I opening were allocated into experimental group, and patients undergoing laparoscopic rectal resection combined with prophylactic ileostomy with stage Ⅱ opening were allocated into control group. Observation indicators: (1) comparison of postoperative clinical endpoints indices; (2) comparison of postoperative complications; (3) comparison of stress response indices. Follow-up was performed using outpatient examination and telephone interview to detect recovery of patients. The patients were followed up for the first time within 24 hours after discharge and kept in contact with the doctor at any time within 1 week after discharge. The patients were followed up at 2 weeks after discharge in outpatient department and then were followed up by telephone interview once a week within 1 month after operation. Patients returned to hospital if there was any discomfort after discharge, and were re-admitted if necessary. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the independent sample t test. Repeated measurement data were analyzed using repeated ANOVA. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact propability. Results: Eighty-eight patients were screened for eligibility, including 61 males and 27 females, aged from 44 to 74 years, with an average age of 61 years. There were 45 patients in the experimental group and 40 in the control group, respectively. (1) Comparison of postoperative clinical endpoints indices: the operation time, time to first semiliquid diet, postoperative fever time, quality of life score, duration of hospital stay, and total hospitalization expenses were (122±9)minutes, (5.1±1.6)days, (54±8)hours, 18.6±1.5, (6.7±1.2)days, (53 269±2 888)yuan in the experimental group, and (128±10)minutes, (6.4±2.4)days, (65±7)hours, 17.1±1.3, (8.1±1.4)days, (59 419±1 921)yuan in the control group, respectively. There was no significant difference in operation time or time to first semiliquid diet between the two groups (t=1.716, 1.329, P>0.05). There were significant differences in the postoperative fever time, quality of life score, duration of hospital stay, and total hospitalization expenses between the two groups (t=8.688, 5.850, 3.897, 11.707, P<0.05). (2) Comparison of postoperative complications: the incidence of ileostomy-related complications was 22.2%(10/45) in the experimental group, including 5 cases of ileostomy edema, 2 of fluid and electrolyte imbalance, 2 of fecal dermatitis, 1 of ileostomy infection; the incidence of ileostomy-related complications was 34.9%(15/43) in the control group, including 4 cases of ileostomy edema, 3 of fluid and electrolyte imbalance, 4 of fecal dermatitis, 2 of ileostomy infection, 1 of ileostomy membrane separation, and 1 of ileostomy stenosis; there was no significant difference in the incidence of ileostomy-related complications between the two groups (χ²=1.733, P>0.05). The incidence of system complications was 17.8%(8/45) in the experimental group, including 2 case of acute urinary retention, 2 of incisional infection, 1 of abdominal infection, 1 of pulmonary infection, 1 of urinary infection, 1 of deep venous thrombosis of the lower extremities; the incidence of system complications was 20.9%(9/43) in the control group, including 1 case of acute urinary retention, 1 of incisional infection, 1 of intestinal obstruction, 1 of pulmonary infection, 1 of urinary infection, 1 of deep venous thrombosis of the lower extremities, 1 of anastomotic fistula; there was no significant difference in the incidence of system complications between the two groups (χ²=0.140, P>0.05). There was no death in the two groups. Patients with postoperative anastomotic leakage in the experimental group were recovered and discharged after re-surgical exploration and continuous abdominal irrigation, and the remaining patients were discharged after active conservative treatment. (3) Comparison of stress response indices: from preoperation to postoperative 5 days, the C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) were changed from (2.2±0.7)ng/L to (43.9±12.0)ng/L, from (12.2±1.9)fmmol/L to (11.3±1.4)fmmol/L, from (95±17)ng/L to (107±14)ng/L in the experimental group, and from (2.2±0.8)ng/L to (58.8±10.7)ng/L, from (11.6±1.6)fmmol/L to (12.7±1.3)fmmol/L, from (94±16)ng/L to (117±13)ng/L in the control group, respectively, showing significant differences in the changing trends of CRP, TNF-α, IL-6 between the two groups (F=260.042, 55.428, 120.337, P<0.05). However, the changing trend within groups had interactive effects with time, showing no significant difference (F=3.514, 2.366, 1.864, P>0.05). Conclusion Compared with stage Ⅱ opening, stage Ⅰ opening of prophylactic ileostomy in laparoscopic rectal resection for low rectal cancer is safe and effective, which can reduce postoperative stress response and promote patients′ rehabilitation.

Deep vein thrombosis (DVT) refers to a venous reflux disorder caused by abnormal condensation of blood in deep veins,It is detected in cardinal veins of the whole body and often occurred in the lower extremities.Desquamation of thrombus may cause pulmonary embolism (PE).PE and DVT are two clinical manifestations of different stages of the same disease,which are collectively referred to as venous thromboembolism (VTE).Five famous experts in hernia and abdominal wall surgery explored the prevention and treatment of DVT during perioperative period in patients undergoing abdominal wall hernia surgery from different angles based on clinical experiences.Professor Liu Ziwen introduced the epidemiology of DVT during perioperative period in patients undergoing abdominal wall hernia surgery,emphasized its risks,analyzed systematically its mechanisms including slow venous blood flow,vein injury,high blood coagulation state,underlying diseases and specific factors of abdominal wall hernia surgery,focused on mechanisms of inflammation caused by meshes inducing DVT.Professor Zhang Guangyong introduced informatively its diagnosis with clear and careful thinking,from the clinical manifestations to assistant examinations and moreover to Wells quantitative scoring,from general to specific and from qualitative to quantitative,striving to achieve early and precise diagnosis in order to prevent misseddiagnosis or ignoration of its danger level.Professor Li Hangyu emphasized appropriate preventive and treatment measures according to different stages and risk levels by evaluating the risk factors of preoperative,intraoperative and postoperative DVT.Professor Shen Yingmo analyzed special factors of laparoscopic abdominal wall hernia inducing DVT during the perioperative period,and indicated that surgeons should select surgical methods individually after comprehensive evaluation and consideration because of uncertainty of risk degree in laparoscopic and open surgery inducing DVT during perioperative period based on exis-ting evidence-based medicine and related guidelines.Professor Lu Chaoyang introduced three categories of main treatments including anticoagulation therapy,thrombolytic therapy and surgical therapy,and specific drugs,indications,advantages and disadvantages,opportunities,recommended clinicians to select individually and rationally.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy(CADASIL)is a common hereditary disease caused by NOTCH3 gene. The major clinical manifestations includerecurrent small-vessel ischaemic events, migraine, dementia and mood disturbance. Herein, wereport a 32-years-old male presented with right leg weakness and persistent migraine. We carried outneurological exams, genetic testing, blood and cerebrospinal fluid analysis (CSF) as well as magneticresonance imaging (MRI) for the brain and spinal cord. There were no anti-aquaporin-4 antibodiesand oligoclonal bands in the CSF and blood investigations were within the normal range. MRI scansrevealed multiple hyperintense regions in the brain and longitudinally hyperintense signal in spinal cord.Further, we identified a c.383G>A(p.Cys128Tyr) mutation in NOTCH3 gene. Therefore, the patientwas diagnosed with CADASIL concurrent with spinal cord lesion. The patient’s condition slightlyimproved after two weeks treatment with daily dosage of 0.5 g citicoline and 75 mg clopidogrel.
