Objective To observe the influence of Qishen Yiqi Guttate Pills(mainly composed of Astragali Radix,Salviae Miltiorrhizae Radix et Rhizoma,Notoginseng Radix et Rhizoma,and Dalbergiae Odoriferae Lignum)on the clinical efficacy of patients with acute myocardial infarction after percutaneous coronary intervention(PCI).Methods Sixty post-PCI patients with acute myocardial infarction of qi deficiency and blood stasis type who met the inclusion criteria were randomly divided into a treatment group and a control group,with 30 patients in each group.The control group was treated with conventional western medicine,and the treatment group was treated with Qishen Yiqi Guttate Pills on the basis of treatment for the control group.The course of treatment for the two groups lasted for 3 months.The changes of cardiac function indicators and serum levels of hypersensitive C-reactive protein(hs-CRP)and N-terminal B-type natriuretic peptide precursor(NT-pro BNP)were observed before and after the treatment in the two groups,and the incidence of cardiovascular adverse events during the treatment in the two groups were also compared.Results(1)After treatment,the serum hs-CRP and NT-pro BNP levels of patients in the two groups were significantly decreased(P＜0.05)and the left ventricular ejection fraction(LVEF)was significantly increased(P＜0.05)compared with those before treatment.And the effects on lowering the levels of serum hs-CRP and NT-pro BNP and on increasing LVEF of the treatment group were significantly superior to those of the control group,the differences being statistically significant(P＜0.05).(2)During the treatment period,the incidence of cardiovascular adverse events in the treatment group was 6.67%(2/30),which was significantly lower than 26.67%(8/30)of the control group,and the difference was statistically significant when comparing the two groups(P＜0.05).Conclusion Qishen Yiqi Guttate Pills can effectively improve cardiac function,decrease serum hs-CRP and NT-pro BNP levels,and reduce the occurrence of adverse cardiovascular events in post-PCI patients with acute myocardial infarction of qi deficiency and blood stasis type.

Objective To explore the clinical efficacy of modified Xuefu Zhuyu Decoction combined with acupoint application for the treatment of patients with stable angina pectoris in coronary heart disease(SAP-CHD),and to evaluate its clinical value for the treatment of SAP-CHD.Methods A total of 92 patients with SAP-CHD of heart-blood stasis and obstruction complicated with qi deficiency type were randomly divided into control group and observation group,with 46 cases in each group.The control group was treated with conventional western medicine alone,and the observation group was treated with modified Xuefu Zhuyu Decoction combined with acupoint application on the basis of treatment for the control group.The two groups were treated for 4 weeks.The changes of traditional Chinese medicine(TCM)syndrome scores,Pittsburgh Sleep Quality Index(PSQI)scores,cardiac function indicators of left ventricular ejection fraction(LVEF),left ventricular end-systolic diameter(LVESD)and left ventricular end-diastolic diameter(LVEDD),and frequency and duration of angina pectoris in the two groups before and after treatment were observed.After treatment,the TCM syndrome efficacy in the two groups was evaluated.Results(1)After 4 weeks of treatment,the total effective rate of TCM syndrome efficacy in the observation group was 91.30％(42/46),and that of the control group was 76.09％(35/46).The intergroup comparison(tested by chi-square test)showed that the TCM syndrome efficacy in the observation group was significantly superior to that in the control group(P＜0.05).(2)After treatment,the scores of TCM syndromes in the two groups were decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was more significant than that in the control group(P＜0.05).(3)After treatment,the PSQI scores of sleep quality in the two groups were lower than those before treatment(P＜0.05),and the decrease of PSQI score in the observation group was significantly superior to that in the control group after treatment(P＜0.05).(4)In terms of cardiac function,LVEF in the two groups after treatment was higher than that before treatment(P＜0.05),LVESD and LVEDD were lower than those before treatment(P＜0.05).The increase of LVEF and the decrease of LVESD and LVEDD in the observation group were significantly superior to those in the control group after treatment(P＜0.05).(5)After treatment,the frequency and duration of angina pectoris in the two groups were improved compared with those before treatment(P＜0.05),and the improvement in the frequency and duration of angina pectoris in the observation group was superior to that in the control group(P＜0.05).Conclusion On the basis of conventional western medicine treatment,modified Xuefu Zhuyu Decoction combined with acupoint application exerts certain clinical effect for the treatment of patients with stable angina pectoris in coronary heart disease.The combined therapy is effective on improving the cardiac function and sleep quality of the patients,reducing the attack of angina pectoris and shortening the duration of angina pectoris,with stronger efficacy than that of conventional western medicine alone.

Objective:To investigate the influencing of preoperative total bilirubin (TBil) on perioperative complications of hepatolithiasis receiving liver resection.Methods:The retrospective cohort study was conducted. The clinical data of 300 patients with hepatolithiasis who were admitted to 2 medical centers from January 2010 to January 2022 were collected. There were 115 males and 185 females, aged (54±13)years. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for comparison between groups. Measurement data with skewed distribution were represented as M( Q1, Q3), and the Mann-Whitney U test was used for comparison between groups. Count data were expressed as absolute numbers, and the chi-square test was used for comparison between groups. Variables with P<0.10 in the univariate analysis were included into the multivariate analysis. Univariate analysis was conducted using the Logistic regression model,and multivariate analysis was conducted using the Logistic stepwise regression model with backward Wald method. Continuous variables were converted into categorical variables based on commonly reported cutoff values when conducting Logistic regression analysis. Results:(1) Comparison of clinical data of patients with different preoperative TBil. Of 300 patients with hepatolithiasis, there were 252 cases with low level of preoperative TBil as 14.4(11.1,19.7)μmol/L, and there were 48 cases with high level of preoperative TBil as 44.0(31.3,59.8)μmol/L. Of the pati-ents with low level of preoperative TBil, neutrophils percentage was 62%±10%, cases with intra-operative blood transfusion was 29, and cases undergoing anatomical liver resection was 166. Of the patients with high level of preoperative TBil, neutrophils percentage was 70%±11%, cases with intraoperative blood transfusion was 22, and cases undergoing anatomical liver resection was 15. There were significant differences in cases classified as>grade 2 of ASA classification, neutrophils percentage, cases with intraoperative blood transfusion and cases undergoing anatomical liver resection between patients with low and high level of preoperative TBil ( t=5.182, χ2=33.669, 18.775, P<0.05). (2) Comparison of perioperative complications of patients with different preoperative TBil. Of the 252 patients with low level of TBil, there were 151 cases with complications including 35 cases of serious complications, there was 1 case with postoperative liver failure, the duration of postoperative hospital stay was 13.0(10.0,16.0)days. Of the 48 patients with high level of TBil, there were 32 cases with complications including 17 cases of serious complications, there were 6 cases with postoperative liver failure, the duration of postoperative hospital stay was 14.0(10.0,18.8)days. There were significant differences in cases with serious complications and cases with postoperative liver failure between patients with low and high level of preoperative TBil ( χ2=13.041, 20.879, P<0.05). (3) Analysis of factors influencing postoperative serious complications in patients undergoing liver resection. Results of multivariate analysis showed that age, body mass index (BMI), preoperative TBil and volume of intraoperative blood loss were independent factors influencing postoperative serious complications in patients undergoing liver resection for hepatolithiasis ( odds ratio=3.852, 2.358, 2.935, 5.135, 95% confidence interval as 1.478?9.979, 1.110?5.009, 1.398?6.158, 2.088?12.626, P<0.05). Conclusions:Patients with high level of preoperative TBil have a significantly increased risk of postoperative serious complications and liver failure who receive liver resection for hepatolithiasis. Age, preoperative BMI, TBil and volume of intraoperative blood loss are independent factors influencing postoperative serious complications in patients undergoing liver resection for hepatolithiasis.

Objective: To understand the current status of diagnosis and treatment of chronic lymphocytic leukemia (CLL) /small lymphocytic lymphoma (SLL) among hematologists, oncologists, and lymphoma physicians from hospitals of different levels in China. Methods: This multicenter questionnaire survey was conducted from March 2021 to July 2021 and included 1,000 eligible physicians. A combination of face-to-face interviews and online questionnaire surveys was used. A standardized questionnaire regarding the composition of patients treated for CLL/SLL, disease diagnosis and prognosis evaluation, concomitant diseases, organ function evaluation, treatment selection, and Bruton tyrosine kinase (BTK) inhibitor was used. Results: ①The interviewed physicians stated that the proportion of male patients treated for CLL/SLL is higher than that of females, and the age is mainly concentrated in 61-70 years old. ②Most of the interviewed physicians conducted tests, such as bone marrow biopsies and immunohistochemistry, for patient diagnosis, in addition to the blood test. ③Only 13.7% of the interviewed physicians fully grasped the initial treatment indications recommended by the existing guidelines. ④In terms of cognition of high-risk prognostic factors, physicians' knowledge of unmutated immunoglobulin heavy-chain variable and 11q- is far inferior to that of TP53 mutation and complex karyotype, which are two high-risk prognostic factors, and only 17.1% of the interviewed physicians fully mastered CLL International Prognostic Index scoring system. ⑤Among the first-line treatment strategy, BTK inhibitors are used for different types of patients, and physicians have formed a certain understanding that BTK inhibitors should be preferentially used in patients with high-risk factors and elderly patients, but the actual use of BTK inhibitors in different types of patients is not high (31.6%-46.0%). ⑥BTK inhibitors at a reduced dose in actual clinical treatment were used by 69.0% of the physicians, and 66.8% of the physicians had interrupted the BTK inhibitor for >12 days in actual clinical treatment. The use of BTK inhibitors is reduced or interrupted mainly because of adverse reactions, such as atrial fibrillation, severe bone marrow suppression, hemorrhage, and pulmonary infection, as well as patients' payment capacity and effective disease progression control. ⑦Some differences were found in the perceptions and behaviors of hematologists and oncologists regarding the prognostic assessment of CLL/SLL, the choice of treatment options, the clinical use of BTK inhibitors, etc. Conclusion: At present, a gap remains between the diagnosis and treatment of CLL/SLL among Chinese physicians compared with the recommendations in the guidelines regarding the diagnostic criteria, treatment indications, prognosis assessment, accompanying disease assessment, treatment strategy selection, and rational BTK inhibitor use, especially the proportion of dose reduction or BTK inhibitor discontinuation due to high adverse events.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

Objective:To provide more options for preoperative localization diagnosis in patients with primary hyperparathyroidism (PHPT), the diagnostic efficacy of parathyroid 4-dimensional computed tomography (4D-CT) in patients with PHPT was evaluated.Methods:This was a single-center retrospective study including 57 patients with surgical proved PHPT. All of the patients underwent 4D-CT, 99Tc m -sestamibi parathyroid imaging (MIBI), and ultrasonography (US) preoperatively. The reference standard for correct localization was based on operation reports and pathology confirmation. The patients were grouped according to the preoperative serum calcium levels, tumor diameter, or ectopic lesions (yes/no), respectively. The sensitivity, specificity, positive predictive value, negative predictive value and area under the curve (AUC) of 4D-CT, MIBI and US, alone or in combination, were analyzed in total and each subgroup patients. Results:Fifty-seven patients (39 women, 18 men; mean age of 56.5 years) were evaluated, including four cases with multi-gland disease and thirteen cases with ectopic parathyroid lesions. In all the patients, similar diagnostic efficacy was found in 4D-CT (AUC: 0.943) and MIBI (AUC: 0.927), both of which were higher than that of US (AUC: 0.847) ( P = 0.01 for 4D-CT vs. US; P = 0.04 for MIBI vs. US). In a subset analysis for ectopic quadrants, the diagnostic efficacy of 4D-CT was significantly higher than that of MIBI ( P = 0.04) or US ( P = 0.01), with the sensitivity of 100%, 69.2%, and 61.5%, and AUC of 0.989, 0.846, and 0.808 for 4D-CT, MIBI and US, respectively. Conclusions:4D-CT has similar diagnostic efficacy for preoperative localization to MIBI in patients with PHPT, and it is superior to MIBI and US in identifying the ectopic parathyroid gland. 4D-CT can be recommended as an alternative preoperative localization method, especially when parathyroid lesions could not be precisely located by US and MIBI.

Identification of genetic variants via high-throughput sequencing (HTS) technologies has been essential for both fundamental and clinical studies. However, to what extent the genome sequence composition affects variant calling remains unclear. In this study, we identified 63,897 multi-copy sequences (MCSs) with a minimum length of 300 bp, each of which occurs at least twice in the human genome. The 151,749 genomic loci (multi-copy regions, or MCRs) harboring these MCSs account for 1.98％of the genome and are distributed unevenly across chromosomes. MCRs containing the same MCS tend to be located on the same chromosome. Gene Ontology (GO) anal-yses revealed that 3800 genes whose UTRs or exons overlap with MCRs are enriched for Golgi-related cellular component terms and various enzymatic activities in the GO biological function cat-egory. MCRs are also enriched for loci that are sensitive to neocarzinostatin-induced double-strand breaks. Moreover, genetic variants discovered by genome-wide association studies and recorded indbSNP are significantly underrepresented in MCRs. Using simulated HTS datasets, we show that false variant discovery rates are significantly higher in MCRs than in other genomic regions. These results suggest that extra caution must be taken when identifying genetic variants in the MCRs via HTS technologies.

To study the effect of serum containing Xihuang pill on the proliferation of human breast cancer cell lines MDA-MB-435 and MCF-7 and the gene and protein expressions of Bcl-2, Bax, TP53, in order to explore the effect and mechanism of Xihuang pill in resisting breast cancer. The serum of the rats was prepared by the method of MTT assay. The expressions of Bcl-2 and Bax were detected by RT-PCR. The serum levels of Bcl-2 and Bax and the mRNA expression of TP53 were detected by immunofluorescence. The rats with serum containing Xihuang pill could inhibit the proliferation of MDA-MB-435 cells and MCF-7 cells (<0.05). The serum containing Xihuang pill increased TP53 and Bax in MDA-MB-435 cells (<0.05), and the ratio of Bcl-2/Bax was decreased (<0.05). Meanwhile, the serum containing Xihuang pill could up-regulate the mRNA expression of Bax in MCF-7 cells and decrease the expression of Bcl (<0.05), but there was no significant difference between the expression of TP53mRNA and Bax protein expressions after the treatment of MCF-7 cells with Xihuang pill serum. Serum containing Xihuang pill can induce the apoptosis of human breast cancer cells, and the mechanism of estrogen receptor-negative breast cancer cell apoptosis may be induced by up-regulating the mRNA expression of TP53, which can induce the expression of Bax and promote the metastasis of Bax to mitochondria, and ultimately play the role of inducing apoptosis.

OBJECTIVETo understand the characteristics of infections from blood donors with HBsAg⁻/HBV DNA⁺ in Xiamen area.

METHODSDonors in Xiamen area were assayed by routine ELISA and those with negative results were tested by nucleic acid amplification testing (NAT). HBsAg⁻/HBV DNA⁺ samples were tested by quantitative detection of HBV DNA. Epidemiological analysis and following up examination were conducted in HBsAg⁻/HBV DNA⁺ donors.

RESULTSOut of 130659 samples 113 were tested as HBsAg⁻/HBV DNA⁺ and with a rate of 0.09%. Among those, 62 samples were tested by quantitative detection of HBV DNA. All of the quantitative results were less than 1 × 10³ IU/ml and 93.5% (58/62) of which were less than 100 IU/ml. The possitive rate of HBsAg⁻/HBV DNA⁺ donors rose with ages. The possitive rate in male donors was higher than that in female and was lower in highly educated ones. Students and public servants had a lower positive rate.

CONCLUSIONThe possitive rate of HBsAg⁻/HBV DNA⁺ donors is higher in Xiamen and the distribution of possitive donors has certain epidemiological characteristics. It is necessary to mobilize and recruit more people with a lower rate of HBsAg⁻/HBV DNA⁺ infection.

OBJECTIVETo investigate the incidence, clinical features and prognostic implications of ischemic hepatitis in hepatitis B related liver cirrhotic patients with upper gastrointestinal hemorrhage.

METHODSBy retrospective review of the medical records of all 264 inpatients with upper gastrointestinal hemorrhage of hepatitis B related liver cirrhosis from January 1st 2007 to November 30th 2008, 11 patients with ischemic hepatitis (IH) were identified. The clinical features and prognostic implications were compared between the IH patients and 30 patients without ischemic hepatitis (control group).

RESULTSThe incidence of ischemic hepatitis was 4.17% in hepatitis B related liver cirrhotic patients with upper gastrointestinal hemorrhage. The patients in IH group were younger than those in control group, the average age was (43.1+/-5.7) in IH group and (52.3+/-11.1) in control group (P=0.013). The serum alanine aminotransferase and aspartate aminotransferase were increased more than 20-fold above the upper limit of normal values, and returned to normal values within 10 days. Compared to the control group, total bilirubin, lactate dehydrogenase, alkaline phosphates, gamma-glutamyltransferase, blood urea nitrogen, creatinine, and white blood cells were increased, while serum cholinesterase was decreased in IH group (P<0.05). The fatality rate of ischemic hepatitis was much higher than that of control group (54.5% vs 16.7%, P=0.041). The main causes of death in IH group were infection, hepatorenal syndrome and hepatic encephalopathy. The patients in IH group lost 200 to 3600 milliliter blood, and hemorrhagic shock occurred in 63.6% (7/11) of IH patients. Therefore the bleeding volume was not correlated with the occurrence rate of ischemic hepatitis.

CONCLUSIONIschemic hepatitis may occur secondary to upper gastrointestinal hemorrhage in hepatitis B related liver cirrhosis. The risk factors of ischemic hepatitis in cirrhositic patients with upper gastrointestinal hemorrhage are young and with hemorrhagic shock, and poor liver function. It is important to use antibiotics in time to improve the prognosis of these patients.
