Objective:The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China.Methods:This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems.Results:According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%).Conclusion:Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

【Objective】 To investigate the clinical application of self-developed magnetic anchoring device for assisting thoracoscopic pulmonary resection. 【Methods】 Eleven patients underwent thoracoscopic pulmonary assisted with resection magnetic anchoring technique at the Department of Thoracic Surgery, The First Affiliated Hospital of Xi’an Jiaotong University, from March to May 2019. Their clinical data were retrospectively analyzed. The operation time, blood loss, blood transfusion volume, postoperative hospital stay, and postoperative complications were recorded. 【Results】 There were seven male and four female patients, with the average age of (51.6±13.9) years (range from 22 to 69 years). Three single-port and eight single-utility-port thoracoscopic surgeries were performed. Magnetic instruments provided good surgical field exposure in all operations. Among 11 surgeries, one was converted to thoracotomy and one to three-hole surgery due to enlargement and adhesion of hilar lymph nodes. The operation time was (107.8±63.1) minutes (range of 27-182 minutes). The blood loss was 50 (10-50)mL (range of 5-1 000 mL). No blood transfusion was needed during the operation. The postoperative hospital stay was (5.0±1.8) days (range of 3-9 days). No postoperative complications occurred in all the patients. 【Conclusion】 Magnetic anchor technique can effectively alleviate the "chopstick effect" in thoracoscopic surgery. Magnetic anchor technique is safe and feasible in assisting thoracoscopic pulmonary resection.

Coronavirus disease 2019 (COVID-19) can cause great damage to the elderly patients and lead to high mortality. The clinical presentations and auxiliary examinations of the elderly patients with COVID-19 are atypical, due to the physiological ageing deterioration and basal pathological state. The treatment strategy for the elderly patients has its own characteristics and treatment protocol should be considered accordingly. To improve the diagnosis, treatment, and prevention of COVID-19 in the elderly, the Expert Committee of Geriatric Respiratory and Critical Care Medicine, China Society of Geriatrics established the "Expert consensus for the diagnosis, treatment, and prevention of coronavirus disease 2019 in the elderly" . We focused on the clinical characteristics and key points for better treatment and prevention of COVID-19 in the elderly. (1) For diagnosis, atypical clinical presentation of COVID-19 in the elderly should be emphasized, which may be complicated by underlying disease. (2) For treatment, strategy of multiple disciplinary team (mainly the respiratory and critical care medicine) should be adopted and multiple systemic functions should be considered. (3) For prevention, health care model about integrated management of acute and chronic diseases, in and out of hospital should be applied.

Objective To compare the difference in risks of obstetric complications of singleton pregnancy between women with hyperandrogenic polycystic ovary syndrome (PCOS) and women with normoandrogenic PCOS. Methods Prospective cohort study. This study was a secondary analysis of data collected during a multicenter randomized controlled clinical trial. Women who got clinical singleton pregnancy were grouped according to whether they were diagnosed with hyperandrogenism at baseline. There were 118 women with hyperandrogenism and 366 women without hyperandrogenism. The incidences of obstetric complications and birth weight were compared between the two groups. Results Women with hyperandrogenic PCOS had a significantly higher risk of preterm delivery than women with normoandrogenic PCOS [12.7％ (15/118) versus 3.6％ (13/366); OR=3.94, 95％CI: 1.82-8.56]. After adjustment of age, duration of infertility, body mass index, and fresh or frozen embryo transfer group, hyperandrogenism was still associated with an increased risk of preterm delivery (OR=3.67, 95％CI: 1.67-8.07). Compared with women with normoandrogenic PCOS, women with hyperandrogenic PCOS had similar risks of pregnancy loss, gestational diabetes mellitus, pre-eclampsia, placenta previa, and postpartum hemorrhage (all P>0.05). Birth weight as well as the risks of being small for gestational age and large for gestational age were also comparable between the two groups (all P>0.05). Conclusion In women with PCOS and singleton pregnancy, those with preconceptional hyperandrogenism have a higher risk of preterm delivery than those without hyperandrogenism.

A 67-year-old female patient with severe osteoporosis received an intravenous infusion of zoledronic acid injection 5 mg(100 ml). Twenty-four hours later,the patient developed conjunctival congestion in bilateral eyes,blurred vision,and difficult lifting of the right eyelid. Ofloxacin eye drops and polyethylene glycol eye drops were given,but the above symptoms were not improved markedly. On the 3rd day of zoledronate acid injection,conjunctivitis with blepharoptosis was diagnosed by an ophthalmologist. On the 4rd day,tobramycin dexamethasone eye drops and esculin and digitalisglycosides eye drops were given. Eight days later,the patient's eyes discomfort disappeared. It was considered that conjunctivitis with blepharoptosis was induced by zoledronic acid injection.

OBJECTIVE:To investigate the effects of aerosol inhalation of budesonide combined with Compound ipratropium bromide on therapeutic efficacy and safety of patients with pneumoconiosis during perioperative period of massive whole-lung la-vage (WLL). METHODS:One hundred and fifty male patients with pneumoconiosis receiving WLL under general anesthesia se-lected from our hospital during Dec. 2014-May 2016 were divided into treatment group and control group in accordance with ran-dom number table,with 75 cases in each group. Both groups received WLL under general anesthesia as well as pure-oxygen manu-al positive pressure ventilation alternating with negative pressure drainage keeping interval and respiratory rate of ventilator synchro-nization. Treatment group was given Budesonide suspension 2 mL,bid+ Compound ipratropium bromide solution 2.5 mL,tid,by aerosol inhalation from 3 d before surgery to 3 d after surgery. The levels of arterial blood gas indexes(pH,PaO2,PaCO2,BE)at different lavage stages,lung function indexes (FVC,MVV,FEV1/FVC),blood gas indexes and clinical symptom score 3 d be-fore surgery and 7 d after surgery were observed in 2 groups,and the occurrence of ADR was recorded. RESULTS:After two-lung ventilation for 20 min following unilateral/bilateral lung lavage,PaO2 of 2 groups were all increased significantly compared to be-fore surgery,with statistical significance (P<0.05);but there was no statistical significance between 2 groups (P>0.05). three days after surgery,FVC,MVV,FEV1/FVC and PaO2 of 2 groups were all increased significantly,PaCO2 and clinical symptom score were all decreased significantly. FVC,FEV1/FVC,PaO2 and clinical symptom score of treatment group were significantly bet-ter than those of control group,with statistical significance(P<0.05). The incidence of airway spasm,hypoxemia and airway pres-sure increasing in treatment group were significantly lower than in control group,with statistical significance(P<0.05). CONCLU-SIONS:During perioperative period of WLL,the aerosol inhalation of budesonide combined with Compound ipratropium bromide for patients with pneumoconiosis can improve clinical efficacy of WLL and reduce the occurrence of ADR during surgery.

Objective:To investigate the serum level of C-C chemokine ligand 19 (CCL19)and its clinical significance in rheumatoid arthritis.Methods:The serum CCL19 levels in both rheumatoid ar-thritis (RA)patients and health controls were detected by ELISA.The proportion of peripheral blood B cells and memory B cell subsets were also detected in some patients.Then the clinical and laboratory data of the patients were collected.The CCL19 levels in patients with different clinical features were analyzed. And the correlation between the clinical data,laboratory parameters,B cell subsets proportion and serum CCL19 levels were also analyzed.Independent samples t test,paired t test,Pearson and Spearman corre-lation were used for statistical analysis.Results:The levels of CCL19 was higher in the RA patients than the health controls (P <0.05).The serum CCL19 levels were decreased in the RA patients who accep-ted disease-modifying anti-rheumatic drugs (DMARDs)treatment for 6 months (P <0.001 ).Serum CCL19 levels were correlated with the titers of both rheumatoid factor (RF)and anti-cyclic citrullinated peptide (CCP)antibody (r =0.42,P =0.002;r =0.33,P =0.013),but not with erythrocyte sedi-mentation rate (ESR),C-reactive protein (CRP)and disease activity score in 28 joints (DAS28)(P >0.05).The levels of CCL19 were higher in the serum positive (RF and anti-CCP antibody)patients,but there were no differences between low and high disease activity RA,as well as early and non-early RA. There was no correlation between the serum CCL19 levels and the proportion of B cells as well as memory B subsets.All the proportion of peripheral blood CD27 + memory B cell subsets in RA was lower than the healthy controls,including CD27 +IgD +,CD27 +IgD - and CD27 + B cells.Conclusion:The increased serum CCL19 levels in RA patients are associated with the activity of B cells,so CCL19 might predict whether the RA type is a B cell mediated RA,and specify the treatment directions for the rheumatologist.

Objective To investigate the method to isolate and culture hepatic stellate cells ( HSCs) for studying the cellular mechanisms of hepatic frbrosis.Methods HSCs were isolated by nycodenz density gradient centrifugation after the hepatocytes obtained from adult male gebils were digested with pronase, collagenase and DNase, infused via portal vein.The cell viability was determined by trypan blue exclusion test.The purity of HSCs was identified by detectingα-SMA, desmin immunohistochemical staining.Results The yield rate of HSCs was 0.5~1 ×107 per gerbil liver, and the cell viability was more than 90%.The percentage ofα-SMA-positive cells was more than 75%after 3 days primary culture and almost 100% cells were α-SMA and desmin positive in passage culture.Conclusion The successful protocol of primary culture of Mongolian gerbil HSC provide a technical support for research of relevant liver diseases and drug development in the future.
