BACKGROUNDLung cancer has become the leading cause of death in many regions. Carcinogenesis is caused by the stepwise accumulation of genetic and chromosomal changes. The aim of this study was to investigate the chromosome and gene alterations in the human lung adenocarcinoma cell line OM.

METHODSWe used Giemsa banding and multiplex fluorescence in situ hybridization focusing on the human lung adenocarcinoma cell line OM to analyze its chromosome alterations. In addition, the gains and losses in the specific chromosome regions were identified by comparative genomic hybridization (CGH) and the amplifications of cancer-related genes were also detected by polymerase chain reaction (PCR).

RESULTSWe identified a large number of chromosomal numerical alterations on all chromosomes except chromosome X and 19. Chromosome 10 is the most frequently involved in translocations with six different interchromosomal translocations. CGH revealed the gains on chromosome regions of 3q25.3-28, 5p13, 12q22-23.24, and the losses on 3p25-26, 6p25, 6q26-27, 7q34-36, 8p22-23, 9p21-24, 10q25-26.3, 12p13.31-13.33 and 17p13.1-13.3. And PCR showed the amplification of genes: Membrane metalloendopeptidase (MME), sucrase-isomaltase (SI), butyrylcholinesterase (BCHE), and kininogen (KNG).

CONCLUSIONSThe lung adenocarcinoma cell line OM exhibited multiple complex karyotypes, and chromosome 10 was frequently involved in chromosomal translocation, which may play key roles in tumorigenesis. We speculated that the oncogenes may be located at 3q25.3-28, 5p13, 12q22-23.24, while tumor suppressor genes may exist in 3p25-26, 6p25, 6q26-27, 7q34-36, 8p22-23, 9p21-24, 10q25-26.3, 12p13.31-13.33, and 17p13.1-13.3. Moreover, at least four genes (MME, SI, BCHE, and KNG) may be involved in the human lung adenocarcinoma cell line OM.

Objective:To investigate the influence and mechanism of stromal interaction molecule 1 (STIM1) in microglia/macrophages M1 activation after cerebral ischemia-reperfusion injury.Methods:(1) Animal experiment: 20 male C57BL/6J mice were randomly divided into sham-operated (Sham) group, middle cerebral artery occlusion and reperfusion (MCAO/R) group, MCAO/R+si-Ctrl group, and MCAO/R+si-STIM1 group ( n=5); MCAO/R models were established in mice of the latter 3 groups; empty vector control virus and STIM1 gene knockout lentivirus were transfected into mice in the MCAO/R+si-Ctrl group and MCAO/R+si-STIM1 group. The transfection efficiency of STIM1 and the expression of microglia/macrophages M1 activation marker cluster of differentiation 86 (CD86) in each group were observed. (2) Cell experiment: primary microglia were divided into Ctrl group, oxygen-glucose deprivation/re-oxygenation (OGD/R) group, OGD/R+si-Ctrl group, OGD/R+si-STIM1 group, OGD/R+solvent group, and OGD/R+4-phenylbutyric acid (4-PBA) group; OGD/R models were established in the later 5 groups; empty vector control virus and STIM1 gene knockout lentivirus were transfected into mice in the OGD/R+si-Ctrl group and OGD/R+si-STIM1 group; cells in the OGD/R+4-PBA group were pre-treated with 1 mmol/L 4-PBA for 1 h at 24 h before OGD/R modelling to inhibit endoplasmic reticulum stress (ERS), and cells in the OGD/R+solvent group were pre-treated with 0.5% dimethyl sulfoxide (DMSO) for 1 h at the same time. Reverse transcription quantitative polymerase chain reaction (RT-qPCR), ELISA, Western blotting and other methods were used to detect the levels of CD86, tumour necrosis factor-α ( TNF-α) mRNA, interleukin (IL)-1β, and ERS-related proteins (transcription factor C/EBP homologous protein [CHOP], activated transcription factor 4 [ATF4]) in these cells. Results:(1) Animal experiment: the STIM1 expression in MCAO/R+si-STIM1 group was significantly lower than that in Sham group, MACO/R group and MCAO/R+si-Ctrl group ( P<0.05); as compared with that in the MACO/R group and MCAO/R+si-Ctrl group, the number of microglia/macrophages co-expressing CD86 and Iba-1 around the ischemic foci of mice in the MCAO/R+si-STIM1 group was significantly decreased ( P<0.05). (2) Cell experiment: as compared with those in the OGD/R group and OGD/R+si-Ctrl group, the expression levels of STIM1, CD86, and TNF-α mRNA, and supernatant IL-1β content in the OGD/R+si-STIM1 group were significantly decreased ( P<0.05); as compared with those in the OGD/R group and OGD/R+si-CTRL group, the ATF4 and CHOP expression levels in OGD/R+si-STIM1 group were significantly decreased ( P<0.05); as compared with those in the OGD/R group and OGD/R+solvent group, the CD86 level, TNF-α mRNA expression level and IL-1β content in the OGD/R+4-PBA group were significantly decreased ( P<0.05). Conclusion:STIM1 affects microglia/macrophages M1 activation after ischemia-reperfusion injury by regulating ERS level.

OBJECTIVE To evaluate the clinical effects of TCM diagnosis and treatment project for patients with MODS gastrointestinal dysfunction of abdominal distension and fullness disease.METHODS TCM diagnosis and treatment project (draft protocol)for abdominal distention and fullness disease was decided according to MODS diagnosis criteria which was for-mulated in the 3rd CSCCM.Seventy-eight patients with abdominal distension and fullness disease included in ICU of the affilia-ted hospital of Nanjing University of Chinese Medicine from July,2012 to December,2016 were enrolled in this study,and were randomly divided into the control group(n=35)and the treatment group(n=43).Basic treatments such as active anti-infection,functional support of organs,immuno-nutrition supplement were performed for both groups.For the treatment group,patients who were diagnosed as the syndrome of middle-heat obstruction were treated with the modified Dahuang Huan-glian Xiexin decoction to eliminate stagnation,clear away heat and detoxify.patients who were diagnosed as the syndrome of qi stagnation and blood stasis were treated with the modified Xuefu Zhuyu decoction to regulate qi and dredge fu-organs,activate blood circulation and remove blood stasis,and patients who were diagnosed as the qi deficiency of lung and spleen were treated with the self-formulated Yiqi Tongfu decoction to supplement qi,invigorate spleen and purge fu-organs.In addition,all syn-dromes were also treated with acupuncture and moxibustion and acupoints application.gastrointestinal function related indexes such as abdominal symptoms,signs,intra-abdominal pressure,ICU stays and mortality during hospitalization in both groups were recoded and compared on the 7th and 14th day before and after the treatment.RESULTS TCM Symptom score,abdomi-nal signs score,intra-abdominal pressure level in both groups showed a downward trend after the treatment,but all indexes in the treatment group decreased more significantly on the 7th and 14th day compared with those of the control group,the differ-ences had statistical significance(P<0.05),and the TCM symptom score and abdominal signs score decreased more signifi-cantly on the 14th day(P<0.01).The mortality rate of two groups during 28 days showed no significant difference,but the mean ICU stays in treatment group was lower than that in the control group(P<0.05).Treatment group Analysis showed that the proportion of the middle-heat obstruction patients was the highest,and the recovery rate of whom was obviously higher than that of patients belong to syndromes of qi stagnation and blood stasis,qi deficiency of spleen and lung,while the ineffec-tive rate was lower than those of the other two syndromes(P<0.05).CONCLUSIONS For hospitalized patients with abdom-inal distention and fullness disease,the application of TCM diagnosis and treatment project can significantly improve the clinical effect and decrease ICU stays.

Objective:To summarize the experience of surgical treatment of primary liver cancer.Methods:The clinical data of 10 966 surgically managed cases with primary liver cancer, from January 1986 to December 2019 at Hepatobiliary Center, the First Affiliated Hospital of Nanjing Medical University, were retrospectively analyzed. The life table method was used to calculate the survival rate and postoperative recurrence rate. Log‐rank test was used to compare the survival process of different groups, and the Cox regression model was used for multivariate analysis. In addition, 2 884 cases of hepatocellular carcinoma(HCC) with more detailed follow‐up data from 2009 to 2019 were selected for survival analysis. Among 2 549 patients treated with hepatectomy, there were 2 107 males and 442 females, with an age of (56.6±11.1) years (range: 20 to 86 years). Among 335 patients treated with liver transplantation, there were 292 males and 43 females, with an age of (51.0±9.7) years (range: 21 to 73 years). The outcomes of hepatectomy versus liver transplantation, anatomic versus non-anatomic hepatectomy were compared, respectively.Results:Of the 10 966 patients with primary liver cancer, 10 331 patients underwent hepatectomy and 635 patients underwent liver transplantation. Patients with liver resection were categorized into three groups: 1986－1995(712 cases), 1996－2008(3 988 cases), 2009?2019(5 631 cases). The 5‐year overall survival rate was 32.9% in the first group(1986－1995). The 5‐year overall survival rate of resected primary liver cancer was 51.7% in the third group(2009‐2019), among which the 5‐year overal survival rates of hepatocellular carcinoma, intrahepatic cholangiocarcinoma and mixed liver cancer were 57.4%, 26.6% and 50.6%, respectively. Further analysis was performed on 2 549 HCC patients with primary hepatectomy. The 1‐, 3‐, 5‐, and 10‐year overall survival rates were 88.1%, 71.9%, 60.0%, and 41.0%, respectively, and the perioperative mortality rate was 1.0%. Two hundred and forty‐seven HCC patients underwent primary liver transplantation, with 1‐, 3‐, 5‐, and 10‐year overall survival rates of 84.0%, 64.8%, 61.9%, and 57.6%, respectively. Eighty‐eight HCC patients underwent salvage liver transplantation, with the 1‐, 3‐, 5‐, and 10‐year overall survival rates of 86.8%, 65.2%, 52.5%, and 52.5%, respectively. There was no significant difference in survival rates between the two groups with liver transplantation ( P>0.05). Comparing the overall survival rates and recurrence rates of primary hepatectomy (2 549 cases) with primary liver transplantation (247 cases), the 1‐, 3‐, 5‐, and 10‐year overall survival rates in patients within Milan criteria treated with hepatectomy and transplantation were 96.3%, 87.1%, 76.9%, 54.7%, and 95.4%, 79.4%, 77.4%, 71.7%, respectively ( P=0.754). The 1‐, 3‐, 5‐year recurrence rates were 16.3%, 35.9%, 47.6% and 8.1%, 11.7%, 13.9%, respectively( P<0.01). The 1‐, 3‐, 5‐, 10‐year overall survival rates in patients with no large vessels invasion beyond the Milan criteria treated with liver resection and transplantation were 87.2%, 65.9%, 53.0%, 33.0% and 87.6%, 71.8%, 71.8%, 69.3%, respectively( P=0.003); the 1‐, 3‐, 5‐year recurrence rate were 39.2%, 57.8%, 69.7% and 29.7%, 36.7%, 36.7%, respectively ( P<0.01). The 1‐, 3‐, 5‐, and 10‐year overall survival rates in patients with large vessels invasion treated with liver resection and transplantation were 62.1%, 36.1%, 22.2%, 15.0% and 62.9%, 31.8%,19.9%, 0, respectively ( P=0.387); the 1‐, 3‐, 5‐year recurrence rates were 61.5%, 74.7%, 80.8% and 59.7%, 82.9%, 87.2%, respectively( P=0.909). Independent prognostic factors for both overall survival and recurrence‐free survival rates of HCC patients treated with liver resection included gender, neoadjuvant therapy, symptoms, AST, intraoperative or postoperative blood transfusion, tumor number, tumor size, cirrhosis, macrovascular invasion, microvascular invasion, and pathological differentiation. Propensity score matching analysis of 443 pairs further showed that there was no significant difference in overall survival rate between anatomical liver resection and non‐anatomical liver resection( P=0.895), but the recurrence rate of non‐anatomical liver resection was higher than that of anatomical liver resection( P=0.035). Conclusions:In the past decade, the overall survival rate of HCC undergoing surgical treatment is significantly higher than before. For HCC patients with good liver function reservation, surgical resection can be performed first, and salvage liver transplantation can be performed after recurrence. The effect of salvage liver transplantation is comparable to that of primary liver transplantation. As for the choice of liver resection approaches, non‐anatomical resection can reserve more liver tissue and can be selected as long as the negative margin is guaranteed.

Objectives: To investigate the prevalence and associated risk factors of tinnitus in Sichuan and Chongqing. Methods: We designed a tinnitus epidemiological questionnaire. The multi-stage stratified cluster random sampling methods was applied to obtain study subjects in six areas (Nanchong, Jiangjin, Fengdu, Yunyang, Suining and Ya'an), which were selected for epidemiological investigation. Home visit completion of epidemiological questionnaires was conducted. The trained investigators guided the respondents to fill in the tinnitus epidemiological questionnaires, and the epidemiological status of six areas on prevalence and risk factor was investigated. SPSS 22.0 software was used for statistical analysis. Results: Sampling population were 10 289, in which 9 273 were valid questionnaires. There were 4 281 males and 4 992 females, with an average age of 47.3 years, among which 34.83% (3 230/9 273) had tinnitus. 3.99% (370/9 273) were diagnosed with bothersome tinnitus. In a multivariable logistic regression mod, the following factors were associated with onsetting of tinnitus: sleep disorder [Odds Ratio(OR)=3.74] and noise exposure(OR=1.99). The risk of disease was lowest in the age of 30-40 years old, while the risk of disease was higher for people under 30 and over 40. In another multivariable logistic regression mode, the following factors were associated with having bothersome tinnitus: older people were more likely to suffer from tinnitus, sleep disorders (OR=4.68) and noise exposure (OR=1.56). Conclusions: The prevalence of tinnitus in Sichuan and Chongqing is about 34.83%, but most of the tinnitus is short-lived and has low loudness, which will not affect the patients. Only a small number of patients with tinnitus (3.99%) persist and affect their health and need treatment. The occurrence and exacerbation of tinnitus may be related to sleep, age, and noise exposure.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
