Objective To investigate the infection status and changing trend of hepatitis C virus(HCV)infection in hospitalized patients in medical institutions,and provide reference for formulating HCV infection prevention and control strategies.Methods HCV infection surveillance results from cross-sectional survey data reported to China Healthcare-associated Infection(HAI)Surveillance System in 2020 were summarized and analyzed,HCV positive was serum anti-HCV positive or HCV RNA positive,survey result was compared with the survey results from 2003.Results In 2020,1 071 368 inpatients in 1 573 hospitals were surveyed,738 535 of whom underwent HCV test,4 014 patients were infected with HCV,with a detection rate of 68.93％and a HCV positive rate of 0.54％.The positive rate of HCV in male and female patients were 0.60％and 0.48％,respectively,with a statistically sig-nificant difference(x2=47.18,P＜0.001).The HCV positive rate in the 50-＜60 age group was the highest(0.76％),followed by the 40-＜50 age group(0.71％).Difference among all age groups was statistically signifi-cant(x2=696.74,P＜0.001).In 2003,91 113 inpatients were surveyed.35 145 of whom underwent HCV test,resulting in a detection rate of 38.57％;775 patients were infected with HCV,with a positive rate of 2.21％.In 2020,HCV positive rates in hospitals of different scales were 0.46％-0.63％,with the highest in hospital with bed numbers ranging 600-899.Patients'HCV positive rates in hospitals of different scales was statistically signifi-cant(X2=35.34,P＜0.001).In 2020,12 provinces/municipalities had over 10 000 patients underwent HCV-rela-ted test,and HCV positive rates ranged 0.19％-0.81％,with the highest rate from Hainan Province.HCV posi-tive rates in different departments were 0.06％-0.82％,with the lowest positive rate in the department of pedia-trics and the highest in the department of internal medicine.In 2003 and 2020,HCV positive rates in the depart-ment of infectious diseases were the highest,being 7.95％and 3.48％,respectively.Followed by departments of orthopedics(7.72％),gastroenterology(3.77％),nephrology(3.57％)and general intensive care unit(ICU,3.10％)in 2003,as well as departments of gastroenterology(1.35％),nephrology(1.18％),endocrinology(0.91％),and general intensive care unit(ICU,0.79％)in 2020.Conclusion Compared with 2003,HCV positive rate decreased significantly in 2020.HCV infected patients were mainly from the department of infectious diseases,followed by departments of gastroenterology,nephrology and general ICU.HCV infection positive rate varies with gender,age,and region.

Consumptive thirst such as dry mouth and polydipsia,frequent urination polyuria,fear of heat and hyperhidrosis and loss of other body fluids,yin deficiency and internal heat expression,and irritability and other abnormal emotional symptoms are common.The Synopsis of Golden Chamber need to be further explored for the treatment of miscellaneous diseases.The dialectical thought has a high clinical application value.Lily disease treatment recommendations in the Synopsis of Golden Chamber are explored.The symptoms of lily disease are varied and uncertain,which are caused by the scattering and wandering aimlessly of heat pathogen.The pathogenesis of lily disease can be examined through external symptoms such as bitter taste in mouth,red urine,and faint and rapid pulse.Diabetes is also closely related to yin deficiency and internal heat,and the pathogenesis of the two is similar.Mental symptoms are common characteristics of lily disease and diabetes.The method taken from the Synopsis of Golden Chamber and Baihe-like prescriptions for the treatment of diabetes are effective.By identifying different patterns,symptoms,and indicators,we can select lily bulb,common anemarrhena,rhizome,figwort root,unprocessed rehmannia root,and other drugs to treat diabetes,in order to improve our understanding of lily disease and provide new ideas for diabetes treatment.

Objective:To investigate the clinical characteristics of patients with keratoconus, and to explore the factors influencing keratoconus severity.Methods:A cross-sectional study was performed.A total of 908 patients (1 476 eyes) with primary keratoconus were enrolled in Henan Eye Hospital from January 2019 to December 2021.The medical history data of patients were collected by face-to-face questionnaire survey.Refractive parameters were measured by subjective optometry.Intraocular pressure (IOP) was measured by a non-contact tonometer, and corrected IOP was calculated by Dresden formula.Corneal topography parameters was obtained using Pentacam HR.The subgroup analysis of clinical characteristics of all patients was performed by age (<21 years, 21~<31 years, ≥31 years) and gender.Disease severity was graded based on steep keratometry (Ks), namely mild (Ks<48 D), moderate (48 D≤Ks<55 D) and severe (Ks≥55 D). The influencing factors of disease severity in keratoconus were analyzed by ordered Logistic regression.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2019[5]). All subjects or guardians were informed of the purpose and significance of the study and written informed consent was obtained.Results:Of the 908 patients, 622 were with bilateral keratoconus and 286 were with unilateral keratoconus.The median age of onset was 20(17, 26) years, and the median age of diagnosis was 21(18, 27) years.The ratio of males to females was 3.05∶1.There were 9.80%(89/908) of the patients having a history of allergy, 25.55%(232/908) having a history of other systemic diseases, and 1.98%(18/908) having a family history of keratoconus.Of the 1 476 affected eyes, 27.57%(407/1 476) were diagnosed as severe keratoconus, and 61.94%(568/917) had a history of eye rubbing.The medians of sphericity, cylindricity, IOP, corrected IOP, Ks, thinnest corneal thickness (TCT), anterior corneal surface elevation (AE) and posterior corneal surface elevation (PE) were -4.00(-7.00, -1.75)D, -3.50(-6.00, -1.50)D, 12.00(10.30, 13.80)mmHg, 15.40(13.60, 17.00)mmHg, 49.85(46.40, 54.90)D, 460.00(425.00, 490.00)μm, 21.00(13.00, 34.75)μm, 51.00(33.00, 75.00)μm, respectively.The spherical refraction, IOP and corrected IOP were lower and the cylindrical refraction was higher in patients at age <21 years than in patients at age 21~<31 years, and the TCT of patients at age <21 years was higher than that at age ≥31 years, and the differences were statistically significant (all at P<0.05). Compared with female patients, male patients had younger onset age, lower spherical refraction, IOP and corrected IOP, as well as higher cylindrical refraction, AE and PE, showing statistically significant differences (all at P<0.05). The spherical refraction and IOP of male patients were lower than those of female patients at age <21 years, and the cylindrical refraction was higher in males than in females among the patients at age 21~<31 years, and the differences were statistically significant (both at P<0.05). Among the patients with onset age <21 years and diagnosis age <21 years, the ratio of males to females in patients with severe keratoconus was higher than those with mild and moderate disease, and the difference was statistically significant (both at P<0.05). Older age of onset was a protective factor for disease severity in keratoconus (odds ratio=0.981, 95% confidence interval: 0.963~0.999). Conclusions:The younger the onset age of keratoconus patients, the more severe the disease.Among the patients with severe keratoconus, there were more male patients, and males have a younger onset age and severer conditions.It is suggested that early screening of keratoconus in children and adolescents should be strengthened in clinical work, and more active prevention and treatment measures should be taken for younger patients, especially males.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

To summarize the status quo of clinical evidence on oral Chinese patent medicine in the treatment of hyperlipidemia through scoping review and thereby provide a reference for clinical application and decision-making in health care. Proprietary Chinese medicines for the treatment of hyperlipidemia （dyslipidemia） were retrieved from relevant catalogs and then screened based on their instructions. Articles on the selected Chinese patent medicines were searched from Chinese and english electronic databases and screened according to the inclusion criteria， followed by data extraction and analysis. The results were described with text and graphs. ①A total of 32 Chinese patent medicines and 1 010 related articles were screened out. ②All the included Chinese patent medicines were made from Chinese medicinal materials， of which 5 were Chinese medicinal extracts，and the remaining 27 were pure Chinese medicinal preparations （the compositions of 1 prescription is confidential）. ③As indicated in the instructions， all the 32 Chinese patent medicines can be used to treat hyperlipidemia with the main syndrome of combined phlegm and blood stasis， and the main effect of them is activating blood and resolving stasis. ④Among the 32 medicines， Xuezhikang tablets （Capsules） and Gypenosides Tablets have the lowest price. ⑤For the 328 key clinical studies， 248 were randomized controlled trials and 80 non-randomized controlled trials. ⑥As for the sample size， randomized controlled trials generally included 28-579 cases， and non-randomized controlled trials 24-152 cases. Clinical studies with more than 200 cases accounted for 9.3% （12/129）. ⑦The most common method was the comparison of the intervention effect of Chinese patent medicine and western medicine （36.5%） and Atorvastatin Calcium Tablets was the preferred western medicine control. The observation duration was generally 56 days （8 weeks）. ⑧In clinical practice， the absolute value of blood lipid decrease and （total） effective rate were often used to evaluate the efficacy， and the effective rate was generally determined based on Clinical Guidelines for New Chinese Medicines. The overall quality of clinical studies on oral Chinese patent medicines is uneven and there is a lack of high-quality clinical evidence. Moreover，there are the risks of unreasonable use and uneasy use of Chinese patent medicine.It is recommended that researchers on proprietary Chinese medicine should further broaden the research ideas，focus on the top-level design of the research plan， and standardize the research process，thereby provide high-quality research evidence for the clinical use of proprietary Chinese medicine. Moreover， more efforts should be made to establish a sound mechanism for information collection and feedback of proprietary Chinese medicine， so as to reduce the risk of uneasy use.We hope that in-depth investigation and discussion should be launched by price， economy， quality evaluation， and other departments headed by the supervision department to make the price of Chinese patent medicine reasonable and fair， thereby promoting the rational use of Chinese patent medicine.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ² test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

BACKGROUND: Coronary artery disease (CAD) is the commonest cause of heart failure (HF), whereas pulmonary hypertension (PH) has not been established or reported in this patient population. Therefore, we assessed the prevalence, risk factors, and survival in CAD-associated HF (CAD-HF) complicated with PH. METHODS: Symptomatic CAD-HF patients were continuously enrolled in this prospective, multicenter registry study. Echocardiography, coronary arteriography, left and right heart catheterization (RHC), and other baseline clinical data were recorded. Patients were followed up and their survival was recorded. RESULTS: One hundred and eighty-two CAD-HF patients were enrolled, including 142 with HF with a preserved ejection fraction (heart failure with preserved ejection fraction [HFpEF]; left ventricular ejection fraction [LVEF] ≥50%) and 40 with a reduced ejection fraction (heart failure with reduced ejection fraction [HFrEF]; LVEF < 50%). PH was diagnosed with RHC in 77.5% of patients. Patients with PH showed worse hemodynamic parameters and higher mortality. HFrEF-PH patients had worse survival than HFpEF-PH patients. CAD-HF patients with an enlarged left ventricular end-diastolic diameter and reduced hemoglobin were at higher risk of PH. Nitrate treatment reduced the risk of PH. Elevated creatinine and mean pulmonary arterial pressure (mPAP), diastolic pressure gradient (DPG) ≥7 mmHg, and previous myocardial infarction (MI) entailed a higher risk of mortality in CAD-HF patients with PH. CONCLUSIONS: PH is common in CAD-HF and worsens the hemodynamics and survival in these patients. Left ventricle enlargement and anemia increase the risk of PH in CAD-HF. Patients may benefit from nitrate medications. Renal impairment, elevated mPAP, DPG ≥7 mmHg, and previous MI are strong predictors of mortality in CAD-HF-PH patients.

OBJECTIVE: To propose the an optimal screw placement scheme to prevent femoral neck shortening, finite element analysis was used to evaluate the biomechanical outcome of different numbers formed by full threaded screws at different positions in the treatment of femoral neck fractures of Pauwels type Ⅱ. METHODS: Recruited for this study was a 55-year-old female volunteer with a weight of 70 kg and a height of 165 cm. CT scan data of her right femur was collected. The models of femoral of Pauwels typeⅡ and fully threaded screw(FTS) and partially threaded screw(PTS) were constructed in three-dimensional modeling software. All these screw placement schemes were divided into eight groups simulated the inverted triangular configuration:three PTSs, an anterosuperior FTS and two PTSs, a posterosuperior FTS and two PTSs, an inferior FTS and two PTSs, an anterosuperior PTS and two FTSs, a posterosuperior PTS and two FTSs, an inferior PTS and two FTSs and three FTSs. All fracture internal fixation models were processed in finite element analysis software. Parameters of postoperative femoral neck length, displacement distribution and peak displacement of screws and VonMises stress distribution and peak stress of screws, the proximal femur and fracture section were collected. RESULTS: The maximum VonMises stress of screws was 239.71, 213.44, 199.37, 230.82, 201.63, 215.72, 185.65 and 192.64 MPa, respectively, which was concentrated in the inferior screw near the fracture line. The maximum Von Mises stress of the proximal femur was 269.48, 241.62, 249.43, 269.69, 271.60, 346.64, 236.97 and 439.62 MPa, respectively, which was concentrated in the inferior medial area of subtrochanteric femur. The maximum Von Mises stress of fracture section was 149.12, 143.04, 140.47, 139.63, 139.81, 130.07, 117.77 and 57.89 MPa, respectively, which was concentrated around the partially threaded screw channel instead of the fully threaded screw channel. The maximum displacement of screws was 5.52, 5.43, 5.32, 5.17, 5.05, 5.13, 5.28 and 5.04 mm, respectively, which was along the axis of the femoral neck, and the displacement distribution was concentrated on the tip of the screw. The length of postoperative femoral neck length was 74.69, 74.72, 74.70, 74.70, 74.72, 74.70, 74.72 and 74.74 mm, respectively. CONCLUSION The placement of one anterosuperior partially threaded screw and two fully threaded screws with an inverted triangular distribution can not only meet the sliding compression effect to promote femoral neck healing and ensure the stability of the proximal femur, but also reduce the degree of postoperative femoral neck shortening and reduce the incidence of hip joint dysfunction. This study provides a new optimal screw placement solution for the treatment of femoral neck fractures.
