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 To investigate the clinical features of patients with acute ST-segment elevation myocardial infarction (STEMI) comorbid with diabetes mellitus (DM) and to analyze the prognosis within 12 months after primary percutaneous coronary intervention (pre-PCI). Methods A total of 375 STEMI patients were divided into the diabetes group (n=140) and the normal blood glucose group(n=235) according to whether they met the diagnostic criteria of DH. The clinical data,characteristics of coronary artery lesions,type of stent implant,rate of coronary slow flow or no-reflow after pre-PCI, and the prognosis within 12 months after PCI of the two groups were investigated.Results Patient in the diabetes group presented with higher mean age ,higher comorbid rates of hypertension , hyperlipidemia and heart function of Killip class Ш and above than patients in the normal blood glucose group (all P<0.05). patients in the diabetes group had higher rates of slow reflow /no-reflow after PCI(12.9% vs.5.5%,P=0.013),higher percentages of 3-ressel disease(40.7% vs. 28.9%,P=0.019)and lef t main lesions(13.6% vs. 7.2%,P=0.044). The in-hospital mortality rates(6.4% vs.1.7%,P=0.020),revascularization rates within 12 months(7.9% vs.0.9%,P=0.001)and incidence of heart failure(7.9% vs. 2.6%,P=0.017)were all higher in the diabetes group. Conclusions STEMI patients comorbid with DM were relatively older, had higher comorbidities of hypertension,hyperlipidemia, three-vessel disease, left main coronary lesions and higher mortality during hospitalization. No significant increase in cardiac death and recurrent myocardial infarction were deserved during the follow-up period. These patients may benefit more from early intervention.

The research studies the effect of different fertilization treatments on yield and accumulation of secondary metabolites of Codonopsis pilosula by using single factor randomized block design, in order to ensure reasonable harvesting time and fertilization ratio, and provide the basis for standardized cultivation of C. pilosula. According to the clustering results, the nitrogen fertilizer benefitted for the improvement of root diameter and biomass of C. pilosula. The phosphate fertilizer could promote the content of C. pilosula polysaccharide. The organic fertilizers could increase the content of lobetyolin. With the time going on, C. pilosula's yield, polysaccharide and ehanol-soluble extracts increased while the content of lobetyolin decreased. According to various factors, October is a more reasonable harvest period. Organic fertilizers are more helpful to the yield and accumulation of secondary metabolites of C. pilosula.

Objective To discuss the indications,feasibility and safety of fluoroscopy-guided retrieval of tracheal tubular metallic stents.Methods Between January 2010 to December 2014,fluoroscopy-guided retrieval of tracheal tubular metallic stent was performed in 45 patients.The stents included 36 covered stents and 9 naked stents.The mean retention time of the covered and naked stents was (3.2±0.7) months and (2.5± 1.2) months respectively.Before the retrieval of the 36 covered stents,granulation tissue hyperplasia in different degrees was observed at both ends of 15 stents,and stent fracture was found in 3 stents.Granulation tissue hyperplasia was seen in all 9 naked stents.Among the 9 naked stents,5 stents were completely embedded in the tracheal submucosal area,and 2 stents were fractured.Results Of the 45 stents,41 stents were successfully retrieved (success rate of 91.1％),including 34 covered stents (94.4％,34/36) and 7 naked stents (77.8％,7/9).Of the 41 patients whose stents were successfully retrieved,massive hemoptysis occurred in 4 patients with a mean bleeding amount of 100 ml,tracheal mucosa tear was detected in 5 patients,emergency airway stent implantation because of tracheal collapse after stent retrieval was needed in one patient,and emergency surgical suture of the trachea due to tracheal rupture was carried out in one patient.No procedure-related death occurred.Conclusion The indications of fluoroscopy-guided retrieval of tracheal tubular metallic stents include stent fracture,local excessive proliferation of granulation tissue or tumor tissue that causes tracheal restenosis,temporary tracheal stent placement for benign tracheal stenosis,intolerance to stent implantation,etc.The technique of fluoroscopy-guided retrieval of tracheal tubular metallic stent is relatively safe and less invasive;this technique can solve the complications induced by long-term retention of the stents.

OBJECTIVETo analyze the incidence and anatomic distribution of venous thrombosis after total hip and knee arthroplasty by using the data of the patients with primary total hip and knee replacement.

METHODSFrom December 2013 to December 2014, total hip and knee arthroplasty were performed in 1 686 patients, of which 928 were THA and 758 were TKA. Before and after discharge, all patients were routinely performed double lower limb vein color Doppler ultrasound, the conventional use of anti fibrinolytic drugs, postoperative anticoagulation for 14 d. The types and distribution of thrombosis after operation were statistical analysis.

RESULTSAmong 928 cases of primary total hip arthroplasty, there were 30 cases of thrombosis, 27 cases of isolated muscle vein thrombosis, followed by the involvement of the anterior or posterior tibial vein thrombosis, no central thrombosis. Among 758 cases of primary total knee arthroplasty, there were 87 cases of thrombosis, 81 cases peripheral thrombosis, 4 cases of thrombus of center type, the remaining 2 cases for mixed thrombus;74 patients with thrombosis involving a single vein, 65 cases involved muscle vein, 4 cases of femoral vein, 3 cases of posterior tibial vein, 2 cases of superficial vein; 13 cases of thrombosis involving multiple veins, involving muscle vein, posterior tibial veins, the peroneal veins and popliteal vein in 2 or 3 branches. The comparison results showed that the incidence of thrombosis after total knee arthroplasty was higher, the difference was statistically significant (<0.001), and more prone to central thrombosis and multiple venous involvement.

CONCLUSIONSThe incidence of thrombosis in patients with primary hip and knee replacement is low, and the incidence and anatomic distribution of the patients with primary hip and knee replacement are different.

BACKGROUNDNontraumatic osteonecrosis of the femoral head (NONFH) is a debilitating disease that represents a significant financial burden for both individuals and healthcare systems. Despite its significance, however, its prevalence in the Chinese general population remains unknown. This study aimed to investigate the prevalence of NONFH and its associated risk factors in the Chinese population.

METHODSA nationally representative survey of 30,030 respondents was undertaken from June 2012 to August 2013. All participants underwent a questionnaire investigation, physical examination of hip, and bilateral hip joint X-ray and/or magnetic resonance imaging examination. Blood samples were taken after overnight fasting to test serum total cholesterol, triglyceride, and high-density lipoprotein (HDL) and low-density lipoprotein (LDL) levels. We then used multivariate logistic regression analysis to investigate the associations between various metabolic, demographic, and lifestyle-related variables and NONFH.

RESULTSNONFH was diagnosed in 218 subjects (0.725%) and the estimated NONFH cases were 8.12 million among Chinese people aged 15 years and over. The prevalence of NONFH was significantly higher in males than in females (1.02% vs. 0.51%, χ2 = 24.997, P < 0.001). Among NONFH patients, North residents were subjected to higher prevalence of NONFH than that of South residents (0.85% vs. 0.61%, χ 2 = 5.847, P = 0.016). Our multivariate regression analysis showed that high blood levels of triglycerides, total cholesterol, LDL-cholesterol, and non-HDL-cholesterol, male, urban residence, family history of osteonecrosis of the femoral head, heavy smoking, alcohol abuse and glucocorticoid intake, overweight, and obesity were all significantly associated with an increased risk of NONFH.

CONCLUSIONSOur findings highlight that NONFH is a significant public health challenge in China and underscore the need for policy measures on the national level. Furthermore, NONFH shares a number of risk factors with atherosclerosis.

OBJECTIVETo investigate whether electroacupuncture (EA) can promote cell survival and enhance heart function of mesenchymal stem cells (MSCs) therapy.

METHODSMSCs were isolated from bone marrow and expanded in Minimum Essential Medium Alpha (α-MEM). MI was induced in 72 Sprague-Dawley (S-D) rats by ligation of the left anterior descending coronary artery (LAD) for 30 min and reperfusion. MI rats randomly received injection of 1×10(6) DiI-labeled MSCs alone (n =24, MSC group), or plus electroacupuncture (EA) at Neiguan (PC6, n=24, EA+MSC group), or saline (n =24, saline group). EA treatment was performed for 4 days. Another 24 rats were subjected to chest-open surgery without LAD occlusion and treatment (sham group). Three time points, 4, 14 and 28 days (n =8 for each group) were included in this study. The survival of transplanted MSCs and the protective gene expression were analyzed by reverse transcriptase polymerase chain reaction (RT-PCR) and Western blot at day 4 and 14. Left ventricular remodeling, cardiac function, infarction area, fibrosis and capillary density were analyzed at day 28.

RESULTSEA can enhance MSC survival (2.6-fold up) at day 4. Big capillary density was 53% higher in EA+MSC treated group than MSC alone group. Furthermore, the rats treated by EA reduced the fibrosis and had 36% smaller infarct size comparing to MSC alone. EA also attenuated left ventricular remodeling and enhanced the functional recovery of infarcted hearts at week 4.

CONCLUSIONEA at Neiguan acupoint can promote the stem cell survival and improve ischemic heart function. EA could become a useful approach in stem cell therapy for ischemia heart diseases.

BACKGROUNDThe initial classic classification of duplex kidney into complete (two ureters) and incomplete ("Y" shaped ureter) types are based on the ureter status. At the meantime, the features of the upper and lower moieties of duplex kidney were very crucial for appropriate procedure of hemi-nephrectomy, which was most commonly used for addressing the issues caused by a duplex kidney; and recently more applications of laparoscopy were used. In this study, we aimed prudently to propose a new classification based on the features of the upper and lower moieties of duplex kidney.

METHODSSixty-five children with 83 duplex kidneys were reviewed retrospectively. Based on kidney morphology found in CT urography and surgical findings, duplex kidney was classified into five types.

RESULTSThe first was the appendant type (36/83) and its feature was that the mini upper moiety was located on top of the lower one, with a visualized shallow groove between them. The ureter was dilated with an ectopic orifice or ureterocele. The second was the embedded type (13/83), the feature of which was that mini upper moiety located in the interior top of the lower one within the same capsule. The upper ureter was dilated with an ectopic orifice or ureterocele. The third was the hydronephrosis type (12/83). The severe hydronephrotic upper moiety was almost as big as the lower moiety. The upper ureter was severely dilated and circuitous with an ectopic orifice. The forth was the dual-poor type (2/83). The two moieties were all very small with "Y" shaped ureters and ectopic orifices. The last was the dual-well type (20/83). The upper moiety was almost the same size as the lower one, without apparent dilation of "Y" shaped or double ureters.

CONCLUSIONBased on kidney morphology, duplex kidney can be mainly classified into five types which can be depicted by CT urography prior to management and can provide an aid in selecting a successful course of surgical correction.
