Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

Background: Esophageal cancer is associated with substantial disease burden in China, and data on the economic burden are fundamental for setting priorities in cancer interventions. The medical expenditure for the diagnosis and treatment of esophageal cancer in China has not been fully quantified. This study aimed to examine the medical expenditure of Chinese patients with esophageal cancer and the associated trends. Methods: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 37 hospitals in 13 provinces/municipalities across China as a part of the Cancer Screening Program of Urban China. For each esophageal cancer patient diagnosed between 2002 and 2011, clinical information and expense data were extracted by using structured questionnaires. All expense data were reported in Chinese Yuan (CNY; 1 CNY= 0.155 USD) based on the 2011 value and inflated using the year-specific health care consumer price index for China. Results: A total of 14,967 esophageal cancer patients were included in the analysis. It was estimated that the overall average expenditure per patient was 38,666 CNY, and an average annual increase of 6.27％ was observed from 2002 (25,111 CNY) to 2011 (46,124 CNY). The average expenditures were 34,460 CNY for stage Ⅰ, 39,302 CNY for stage Ⅱ, 40,353 CNY for stage Ⅲ, and 37,432 CNY for stage IV diseases (P < 0.01). The expenditure also differed by the therapy type, which was 38,492 CNY for surgery, 27,933 CNY for radiotherapy, and 27,805 CNY for chemotherapy (P < 0.05). Drugs contributed to 45.02％ of the overall expenditure. Conclusions: These conservative estimates suggested that medical expenditures for esophageal cancer in China substantially increased in the last 10 years, treatment for early-stage esophageal cancer costs less than that for advanced cases, and spending on drugs continued to account for a considerable proportion of the overall expenditure.

The aim of this study was to investigate the effect of alanine solution as α-N-acetylgalactosaminidase enzyme reaction buffer on the enzymatic activity of A antigen. The binding ability of α-N-acetylgalactosaminidase with RBC in different reaction buffer such as alanine solution, glycine solution, normal saline (0.9% NaCl), PBS, PCS was detected by Western blot. The results showed that the efficiency of A to O conversion in alanine solution was similar to that in glycine solution, and Western blot confirmed that most of enzymes blinded with RBC in glycine or alanine solution, but few enzymes blinded with RBC in PBS, PCS or normal saline. The evidences indicated that binding of enzyme with RBC was a key element for A to O blood group conversion, while the binding ability of α-N-acetylgalactosaminidase with RBC in alanine or glycine solution was similar. It is concluded that alanine solution can be used as enzyme reaction buffer in A to O blood group conversion. In this buffer, the α-N-acetylgalactosaminidase is closely blinded with RBC and α-N-acetylgalactosaminidase plays efficient enzymatic activity of A antigen.

To construct a recombinant replication-defective human adenovirus type 5 expressing Cap protein of PCV2 and test the immunological efficacy in mice. In this study, the recombinant replication-defective human adenovirus type 5, named as rAd5-Cap (wt-rAd5), was constructed through homologous recombination internally in the HEK293AD cells after co-transfection of the Pac I-linearized backbone plasmid and the shuttle plasmid pacAd5CMV-Cap containing the open reading frame (ORF2) of the porcine circovirus type 2 (PCV2) cap protein or pacAd5CMV without inserted fragment. Furthermore, the rAd5-Cap could induce the expression of PCV2 cap protein in the HEK293AD cells with high efficacy evaluated by the RT-PCR and indirect immunofluorescence assay (IFA). The virus titer of rAd5-Cap could reach up to 10(8.5) TCID50/mL similarly to that of wt-rAd5, indicating that there was little affect on the virus proliferation after the insertion of PCV2 cap protein gene. The humeral immune responses could be activated and detected 14 days after the inoculation of the mice with 10(7) TCID50 rAd5-Cap intramuscularly, and constantly in crease in another 14 days. These molecular biological and animal experiments results demonstrated that the PCV2 cap protein could be efficiently expressed by the recombinant adenovirus rAd5-Cap in eukaryotic cells and induce robust immune responses in mice, which laid a good foundation for the development of new type vaccine against porcine circovirus.

OBJECTIVETo investigate the effect of preoperative nutritional support in the management of patients with chronic radiation enteritis (CRE) with intestinal obstruction undergoing resectional surgery.

METHODSClinical data of 158 CRE patients undergoing diseased bowel resection from 2001 to 2011 were analyzed retrospectively. A total of 130 patients received preoperative nutritional support, including 28 patients with enteral nutrition support, 60 patients with total parenteral nutrition support, and 42 patients with combined nutritional support. The nutritional parameters, procedures, operation-related complications, and postoperative hospital stay were recorded.

RESULTSAfter aggressive nutritional support in 130 patients, patients nutritional index, such as serum prealbumin, transferrin, serum albumin improved significantly preoperatively, while the change of body mass index and hemoglobin was not significant. Compared to those without preoperative nutritional support, those who received preoperative nutritional support had lower stoma rate (31.5% vs. 53.6%, P=0.027), less postoperative infection rate (13.8% vs. 32.1%, P=0.019), shorter postoperative hospital stay [(14.1±7.3) d vs. (18.8±15.8) d, P=0.013). Enteral nutrition group had less postoperative infection rate (7.1% vs. 21.7%, P=0.017), lower stoma rate (28.6% vs. 48.3%, P=0.02), and shorter postoperative hospital stay [(15.5±9.6) d vs. (21.7±19.0) d, P=0.025) as compared to total parenteral nutrition group.

CONCLUSIONSPreoperative nutritional support can decrease the stoma rate, postoperative infection rate, and shorten hospital stay in CRE patients complicated with intestinal obstruction. If tolerated, enteral nutrition support should be chosen.
