Objective To investigate the correlations of the expression levels of plasma long non-coding RNA plasmacytoma variant translocation 1 (LncRNA PVT1) and microRNA-143-3p (miR-143-3p) with disease activity and prognosis in patients with rheumatoid arthritis (RA). Methods A total of 129 RA patients admitted to our hospital from April 2021 to April 2023 were selected as disease group. According to the 28-joint disease activity scores (DAS28), the patients were divided into stable disease group (n=28), mildly active group (n=42), moderately active group (n=35), and severely active group (n=24). According to the prognosis of the patients after 6 months of treatment, they were divided into good prognosis group (n=88) and poor prognosis group (n=41), and 110 healthy people who underwent physical examinations in our hospital during the same period were included as control group. The expression levels of plasma LncRNA PVT1 and miR-143-3p were detected using quantitative real-time fluorescent polymerase chain reaction (qRT-PCR). The targeting relationship between LncRNA PVT1 and miR-143-3p was predicted using the Target Scan Human website. Multivariate Logistic regression analysis was conducted to explore the factors influencing the prognosis of RA patients. Receiver operating characteristic (ROC) curve was performed to assess the predictive value of plasma LncRNA PVT1 and miR-143-3p for the prognosis of RA patients. Results The plasma LncRNA PVT1 level in the disease group was higher than that in the control group, while the plasma miR-143-3p level was lower (P < 0.05). The plasma LncRNA PVT1 levels decreased sequentially in the severe activity, moderate activity, mild activity, and disease stable groups, while the plasma miR-143-3p levels increased sequentially (P < 0.05).The proportion of patients positive for human leukocyte antigen-DR4 (HLA-DR4), DAS28, and plasma LncRNA PVT1 expression level were higher in the poor prognosis group than in the good prognosis group, while the plasma miR-143-3p level was lower (P < 0.05). Plasma LncRNA PVT1, miR-143-3p expression, HLA-DR4 positivity, and DAS28 were factors influencing the prognosis of RA patients (P < 0.05). LncRNA PVT1 and miR-143-3p had targeted binding sites, and there was a negative correlation between them (P < 0.05). The area under the curve (AUC) for the combined prediction of plasma LncRNA PVT1 and miR-143-3p for prognosis of RA patients was 0.914, which was superior to the individual diagnosis of LncRNA PVT1 or miR-143-3p (Z=2.159, P=0.031; Z=2.108, P=0.035). The sensitivity and specificity of the combined diagnosis were 95.12% and 78.41%, respectively. Conclusion The plasma LncRNA PVT1 level gradually increases, while the plasma miR-143-3p level gradually decreases with increasing RA disease activity. The combined detection of the two biomarkers has high predictive value for the prognosis of RA patients.

Objective To observe any curative effect of applying comprehensive pulmonary rehabilitation in moderate and severe cases of chronic obstructive pulmonary disease (COPD).Methods A total of 135 persons hospitalized with moderate or severe COPD were randomly divided into a rehabilitation group of 75 and acontrol group of 60.Both groups were given routine treatment,while the rehabilitation group was additionally provided with a comprehensive pulmonary rehabilitation regimen,including health education,exercise training,respiratory function training,respiratory muscle training,psychological support and nutritional intervention for six months.Before and after the treatment,both groups were evaluated using their walking distance within 6 minutes (6MWD),an anhelation index,a COPD assessment test (CAT),the Beck anxiety and depression scale,a nutritional assessment and indexes of pulmonary function and blood gases.Results After the intervention the average 6 MWD,anhelation index,CAT score,Beck anxiety and depression scores,forced expiratory volume,forced vital capacity and PaO2 of the rehabilitation group were all significantly better than before the treatment and better than those of the control group.Conclusion For moderate and severe COPD patients,comprehensive pulmonary rehabilitation effectively strengthens their moving ability,pulmonary function and arterial partial pressure of oxygen,while relieving anhelation,anxiety and depression.

OBJECTIVETo review the experience for the management of hepatocellular carcinoma with tumor thrombus in inferior vena cava.

METHODSFrom July 2003 to May 2005, hepatectomy combined with thrombectomy were performed on 7 cases of hepatocellular carcinoma with tumor thrombus in inferior vena cava. In order to remove the tumor thrombus in inferior vena cava, total hepatic vascular exclusion were adopted on all cases to control the blood flow of IVC. According to the position of extension of tumor thrombus, 5 different procedures were adopted in the cases to control the suprahepatic IVC and extract the tumor thrombus out of IVC and atrium. Procedure 1: Median sternotomy, extracorporeal bypass, cardiac arrest, incision on right atrium and IVC were performed on 1 case for thrombectomy. Procedure 2: Median sternotomy, extracorporeal bypass without cardiac arrest, incision on IVC and (or without) incision on right atrium were performed on 2 cases for thrombectomy. Procedure 3: Abdominal approach to control intrapericardial IVC through an incision on diaphragm was performed on 1 case for thrombectomy. Procedure 4: Abdominal approach to control suprahepatic IVC above diaphragm through a small incision made on vena cava foramen for thrombectomy was performed on 1 case. Procedure 5: Abdominal approaches to control suprahepatic IVC below diaphragm for thrombectomy were performed on 2 cases.

RESULTSAll operations were successfully performed. The postoperative complications included pleural effusion in 1 case, subphrenic fluid collection in 1 case and wound infection in 1 case. The average survival time of 7 cases was 9.8 month. The longest survival time was 26 months.

CONCLUSIONHepatectomy and thrombectomy can be safely performed on the case of HCC combined with tumor thrombus in IVC. Surgical treatment can relieve the patient from the risk of sudden death caused by heart failure and pulmonary.

OBJECTIVETo explore the clinical value and significance of retrograde caudate lobectomy.

METHODSFrom December 2003 to January 2005, 7 patients underwent retrograde caudate lobectomy in which division and ligation of short hepatic veins were carried out at the final stage of the procedure in stead of at the initial stage.

RESULTSThe procedures were carried out smoothly with no operative death in all the 7 cases including isolated complete caudate lobectomy in 4 cases, isolated partial caudate lobectomy in 1 case, combined right half liver resection in 2 case. The average operation time, blood loss and length of stay after operation was (273 +/- 44) min, (1114 +/- 241) ml (800-1500 ml) and 16 days respectively. Complications including pleural effusion and ascites in 1 case respectively were fully recovered. During the follow-up, 1 patient died at 6 months for tumor recurrence in lung and the remaining 6 patients are alive at the follow-up of 5 to 16 months.

CONCLUSIONSRetrograde caudate lobectomy is a new procedure suitable for those caudate neoplasms which are adhering to or infiltrating to IVC or too big to move side by side. The application of this technique can converse certain kind of caudate lobe tumor from non-resectable to resectable resulting in widening the indication.
