ABSTRACT

Objective@#The pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been engendering enormous hazards to the world. We obtained the complete genome sequences of SARS-CoV-2 from imported cases admitted to the Guangzhou Eighth People's Hospital, which was appointed by the Guangdong provincial government to treat coronavirus disease 2019 (COVID-19). The SARS-CoV-2 diversity was analyzed, and the mutation characteristics, time, and regional trend of variant emergence were evaluated.@*Methods@#In total, 177 throat swab samples were obtained from COVID-19 patients (from October 2020 to May 2021). High-throughput sequencing technology was used to detect the viral sequences of patients infected with SARS-CoV-2. Phylogenetic and molecular evolutionary analyses were used to evaluate the mutation characteristics and the time and regional trends of variants.@*Results@#We observed that the imported cases mainly occurred after January 2021, peaking in May 2021, with the highest proportion observed from cases originating from the United States. The main lineages were found in Europe, Africa, and North America, and B.1.1.7 and B.1.351 were the two major sublineages. Sublineage B.1.618 was the Asian lineage (Indian) found in this study, and B.1.1.228 was not included in the lineage list of the Pangolin web. A reasonably high homology was observed among all samples. The total frequency of mutations showed that the open reading frame 1a (ORF1a) protein had the highest mutation density at the nucleotide level, and the D614G mutation in the spike protein was the commonest at the amino acid level. Most importantly, we identified some amino acid mutations in positions S, ORF7b, and ORF9b, and they have neither been reported on the Global Initiative of Sharing All Influenza Data nor published in PubMed among all missense mutations.@*Conclusion@#These results suggested the diversity of lineages and sublineages and the high homology at the amino acid level among imported cases infected with SARS-CoV-2 in Guangdong Province, China.

ABSTRACT

ObjectiveTo investigate the effect of intermittent theta burst stimulation (iTBS) of the multi-target cerebral cortex after stroke on functional recovery of the upper limb of the hemiplegic side. MethodsFrom November, 2019 to August, 2020, 40 stroke patients in Gansu Provine Hospital Rehabilitation Center were included and randomly divided into single-target stimulation group (n = 20) and multiple-target stimulation group (n = 20). Both groups underwent basic neurorehabilitation drug therapy and conventional rehabilitation exercises. The single-target stimulation group received repetitive transcranial magnetic stimulation (rTMS) (iTBS mode) only in the primary motor cortex (M1) of the affected side. The multi-target stimulation group received rTMS (iTBS mode) in the cerebellar cortex of the healthy brain and M1 of the affected side, once a day, six days a week, for four weeks. Before and after treatment, the scores of Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Action Research Arm Test (ARAT) and modified Barthel Index (MBI), and the latency and amplitude of somatosensory-evoked potentials N20 were compared. ResultsNo serious adverse reaction occurred during treatment. After treatment, the scores of FMA-UE, MBI and ARAT, and the amplitude and latency of N20 improved in both groups (|t| > 3.478, |Z| > 2.243, P < 0.05); and the scores of FMA-UE and ARAT, and the amplitude of N20 were better in the multiple-target stimulation group than in the single-target stimulation group (t > 2.939, Z = -2.697, P < 0.01). ConclusionMulti-target stimulation is superior to single-target stimulation for improving upper limb motor function and N20 amplitude in the hemiplegics after stroke.

ABSTRACT

@#AIM: To discuss the clinical effects of pars plana vitrectomy(PPV)combined with interal limiting membrane peeling(ILMP)for macular hole(MH)in pathological myopic eyes.<p>METHODS: This is a retrospective case study. Eighteen patients(19 eyes)with high myopic MH diagnosed in our hospital from January 2017 to January 2019 were enrolled in this study. All eyes were grouped for pathological myopia(9 patients 10 eyes)and non-pathological myopia groups(9 patients 9 eyes). All eyes were treated with PPV combined with ILMP surgery. Postoperative follow up was 3-23mo, the efficacy was determined at the final follow up, including BCVA, visual deformation symptoms and macular hole closure.<p>RESULTS: During the final follow up, BCVA was improved in 6 eyes,stable in 2 eyes, more severe in 2 eyes in pathological myopia group, and MH was fully closed in 7 eyes(70%), bareness-closed in 2 eyes(20%)and not closed in 1 eye(10%). In non-pathological myopia group, BCVA was improved in 6 eyes,stable in 2 eyes, more severe in 1 eyes, and MH was fully closed in 8 eyes(88%), not closed in 1 eye(11%). There were significant differences in the axial length between the two groups before surgery, axial length was negatively correlated with the macular hole closure rate at the last follow up(<i>rs</i>= -0.477, <i>P</i>=0.039).<p>CONCLUSION: PPV combined with ILMP for the treatment of MH in high myopia can effectively improve BCVA. However, the hiatal closure rate of pathological myopia patients was lower than that of non-pathological myopia patients.

ABSTRACT

Objective:To investigate the efficacy and safety of different endoscopic treatment strategies for grade Ⅰ-Ⅲ internal hemorrhoids.Methods:Clinical data of 107 internal hemorrhoid patients who received endoscopic sclerotherapy or band ligation in Renmin Hospital of Wuhan University from December 2018 to December 2020 were retrospectively studied. Postoperative adverse events, efficacy, and satisfaction were followed up.Results:Among the 107 patients, there were 45 patients (42.06%) with grade Ⅰ, 55 (52.34%) with grade Ⅱ, and 6 (5.60%) with grade Ⅲ. At the same time, 94.39% (101/107) patients underwent other gastrointestinal endoscopic treatment. The postoperative follow-up time ranged from 3 to 25 months, with a median of 5 months. A total of 84 patients underwent routine endoscopic injection sclerotherapy, and 8 had adverse events after the surgery. The overall effective rate was 97.61% (82/84), and satisfaction rate was 95.24% (80/84). Nine underwent endoscopic foam sclerotherapy, and no postoperative adverse events were observed. The overall effective rate and the satisfaction rate were both 100.00% (9/9). Among the 11 patients undergoing endoscopic band ligation, 2 had adverse events after the surgery. The overall effective rate was 81.82% (9/11), and the satisfaction rate was 72.73% (8/11). Three patients underwent sclerotherapy combined with ligation, and 2 had postoperative adverse events. The overall effective rate was 100.00% (3/3), and the satisfaction rate was 66.67% (2/3). Sclerotherapy was generally superior to ligation in operation cost. Further subgroup analysis for grade Ⅰ-Ⅱ patients showed that for grade Ⅰ patients, sclerotherapy was better than band ligation in the incidence of postoperative pain ( P<0.05), and for grade Ⅱ patients, no statistically significant differences were observed in adverse events, effective rate and satisfaction rate ( P>0.05). Conclusion:Both endoscopic injection sclerotherapy and band ligation for internal hemorrhoids are safe and effective, and may not increase the risk of adverse events when simultaneously completed with other gastrointestinal endoscopic treatment.

ABSTRACT

Guided by the development of new medical science proposed by Ministry of Education and the "Education and Training Plan for Excellent Doctors 2.0", shifted from treatment-oriented to whole life-health cycle, we have explored curriculum ideological and political education in metabolic-related curriculum chain. Firstly, we constructed a core teaching team and had the training of curriculum ideological and political education. The top-level design was made with the integration of moral education into medical education. Secondly, the syllabus was comprehensively revised, containing the connotation of "morality education". The elements relevant to curriculum ideological and political education hidden behind professional courses were excavated. Finally, the mixed teaching mode of online combining with offline was carried out. Metabolism-related curriculum chain, focused on "metabolism, diabetes, obesity and patient education", formed a progressive link from basic medical science to practice to clinical, strengthening the "prevention, treatment and health care" based "one health" philosophy and giving full play to the implicit curriculum ideological and political education hidden behind professional courses. Our practice shows that the implementation of curriculum ideological and political education in metabolism-related curriculum has been accepted by students, and curriculum ideological and political education has been become part of professional courses. The "gene chimera" mode for curriculum ideological and political education incorporation into professional courses needs to be infiltrated imperceptibly, and the effect will be visualized in the future.

ABSTRACT

Cystine is the primary source material for the synthesis of glutathione.However,the pharmacokinetics and tissue distribution of cystine are largely unknown.A surrogate analyte D4-cystine was employed to generate calibration curves for the determination of levels of D4-cystine and endogenous cystine in mice by liquid chromatography-tandem mass spectrometry(LC-MS/MS).Validation assessments proved the sensitivity,specificity and reproducibility of the method with a lower limit of quantification(LLOQ)of 5 ng/mL over 5-5000 ng/mL in plasma.The pharmacokinetics of D4-cystine were evaluated after administering injections and oral solutions,both of which minimally impacted endogenous cystine levels.The absolute bioavailability of cystine was 18.6%,15.1%and 25.6%at doses of 25,50 and 100 mg/kg,respectively.Intravenously injected D4-cystine resulted in dramatically high plasma levels with reduced levels in the brain and liver.Intragastrically administered D4-cystine resulted in high levels in the plasma and stomach with relatively low levels in the lung,kidney,heart and brain.

ABSTRACT

Ferroptosis is a new type of cell death caused by abnormal accumulation of iron-dependent reactive oxygen species (ROS) and imbalance of redox with the participation of iron ions. In recent years, studies have found that ferroptosis is associated with various diseases and can especially regulate the development of tumors. Chinese medicine has unique advantages in tumor prevention and treatment. How to use ferroptosis theory to guide the prevention and treatment of cancer and other tumor diseases by Chinese medicine is a new research hotspot. This paper summarizes the proposal, action mechanism, and signaling pathway of ferroptosis, its application in tumor therapy, and the research on the activity of Chinese medicine based on ferroptosis. Results found that the occurrence of ferroptosis is related to iron metabolism, lipid ROS metabolism, and other signaling pathways and gene expressions. Ferroptosis can regulate tumor initiation and development, treatment, and tumor immunity, which provides strategies for tumor treatment and anti-tumor drug development. By analyzing the biological activity of Chinese medicine against ferroptosis, we found that Chinese medicines (Scutellariae Radix, Puerariae Lobatae Radix, Astragali Radix, Ginkgo, Epimedii Folium, Artemisiae Annuae Herba, and Salviae Miltiorrhizae Radix et Rhizoma), Chinese herbal compounds ( Naotaifang, Si Junzitang, and Shenmai injection), and Chinese medicine effective components (baicalein, dihydroartemisinin, puerarin, piperlongumine, luteolin, and quercetin) can exert antitumor and other biological activities by regulating ferroptosis. Therefore, Chinese medicine has great potential in preventing and controlling tumors and other diseases by regulating ferroptosis. This paper provides theoretical basis and research ideas for the in-depth study of ferroptosis theory and guides the prevention and treatment of tumor diseases by Chinese medicine.

ABSTRACT

Objective:To discuss clinical effect of addition and subtraction therapy of Ditantang combined with Taohong Siwutang to cerebral infarction and syndrome of phlegm and blood stasis blocking collaterals during early recovery, and to study protection to brain nerve. Method:One hundred and fifty-two patients were randomly divided into control group (76 cases) and observation group (76 cases) by random number table, 71 patients in control group completed the therapy (5 patients were falling off, missing visit or eliminated), and 70 patients in observation group completed the therapy. Both groups' patients got comprehensive rehabilitation measures. Patients in control group got Zhongfeng Huichun pills, 1.5 g/time, 3 times/day. Patients in observation group got addition and subtraction therapy of Ditantang combined with Taohong Siwutang in the morning and at night, 1 dose/day. The treatment was continued for 12 weeks. Before and after treatment, scores of degree of neurological deficit, Barthel (BI) index, Fugl-Meyer scale (FMA), modified Rankin scale (MRS) and syndrome of phlegm and blood stasis blocking collaterals were graded. And levels of malondialdehyde (MDA), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), advanced oxidation protein products (AOPP), vascular endothelial growth factor (VEGF), brain-derived neurotrophic factor (BDNF) and neuron specific enolase (NSE). And cerebral hemodynamics were detected, and peak flow velocity (VS), vascular resistance index (RI), pulsatility index (PI) and cerebrovascular reserve function (CVR) were recorded. Safety was evaluated. Result:After the 6th week and 12th week of treatment, scores of degree of neurological deficit, BI, FMA, MRS, syndrome of phlegm and blood stasis blocking collaterals, AOPP, MDA, NSE, RI and PI were lower than those in control group (P<0.01), levels of SOD, GSH-Px, BDNF, VEGF, Vs and CVR were higher than those in control group (P<0.01). The clinical effect was better than which in control group (Z=2.109, P<0.05). Besides, there was no adverse reaction caused by Ditantang combined with Taohong Siwutang. Conclusion:Ditantang combined with Taohong Siwutang can ameliarate the hemodynamics, reduce the lipid peroxidation damage, regulate the neurovascular repair factor, so it can promote the repair of nerve tissue and function, clinically reduce the degree of nerve function defect, improve the ability of daily life and exercise when it used to cerebral infarction and syndrome of phlegm and blood stasis blocking collaterals during early recovery, and it is good for clinical effect and safe using.

ABSTRACT

Objective:To analyze a family clustering of coronavirus disease 2019 (COVID-19) associated with the exposure to an asymptomatic case, and to provide evidences of developing strategies for COVID-19 prevention. Methods:Epidemiological investigation was conducted on a COVID-19 family cluster (1 confirmed case and 2 asymptomatic cases). The specimens of the cases were tested for 2019 novel coronavirus nucleic acid with real-time fluorescence quantitative polymerase chain reaction. Results:The clustering epidemic occurred in a family. Two asymptomatic cases B and C (B’s son) had Wuhan residential history. After arrival in Beijing on January 24, 2020, B stayed in his mother's house. One family member A (B’s mother) developed the disease on February 7, 2020, while the other two family members D and E (B’s wife and brother) did not develop the disease, and they were managed as close contacts. Conclusion:Thisfamily COVID-19 clustering is induced by the exposure to an asymptomatic case. Identification of asymptomatic cases is very important for the control of COVID-19 epidemic.

ABSTRACT

Objective:To investigate the preoperative diagnostic value of 99Tc m-methoxyisobutylisonitrile (MIBI) planar imaging and SPECT/CT imaging for primary hyperparathyroidism (PHPT), and analyze the relevant factors affecting the imaging results. Methods:From June 2016 to September 2019, a total of 62 patients (15 males, 47 females, age range: 27-80 years) confirmed as PHPT by postsurgical pathology in Affiliated Hospital of Qingdao University were retrospectively enrolled. The diagnostic efficacies of 99Tc m-MIBI planar imaging and SPECT/CT imaging were compared using χ2 test. The differences of preoperative serum parathyroid hormone (PTH), Ca and the maximum diameter of lesion between the positive and negative groups of planar imaging were analyzed using independent-sample t test and Mann-Whitney U test. The region of interest (ROI) method was applied to calculate the uptake ratio of lesions to normal tissues at the early phase (T/Ne) and delayed phase (T/Nd) in positive cases of planar imaging. Pearson or Spearman correlation analysis was used to evaluate the correlation of T/Ne, T/Nd with preoperative serum PTH, Ca and the maximum diameter of lesion. The receiver operating characteristic (ROC) curves of preoperative serum PTH, Ca and positive planar imaging were drawn and the cut-off values were obtained. Results:The sensitivity of planar imaging and SPECT/CT imaging was 69.35%(43/62) and 87.10%(54/62) respectively ( χ2=5.729, P=0.017). The preoperative serum PTH, Ca levels and the maximum diameter of lesion in patients with positive planar imaging (253.32(107.00, 331.70) ng/L, 2.78(2.51, 2.87) mmol/L, (2.01±0.88) mm) were higher than those with negative planar imaging ((111.86±44.29) ng/L, (2.59±0.21) mmol/L, (1.42±0.55) mm; z values: -2.802, -1.978, t=3.300, all P<0.05). T/Ne was positively correlated with preoperative serum PTH ( rs=0.511, P<0.001) and the maximum diameter of lesion ( r=0.381, P=0.012), and T/Nd was positively correlated with preoperative serum PTH ( rs=0.538, P<0.001), Ca ( rs=0.348, P=0.022) and the maximum diameter of lesion ( r=0.463, P=0.002). The area under the ROC curve between preoperative serum PTH, Ca and planar imaging was 0.725 and 0.646, respectively. Preoperative serum PTH had a better predictive value with the optimal cut-off value of 150.4 ng/L. Conclusions:Preoperative serum PTH, Ca and the maximum diameter of lesion are positively correlated with 99Tc m-MIBI uptake in PHPT patients with positive planar imaging results. When preoperative serum PTH is lower than 150.4 ng/L, planar imaging is prone to false negative. SPECT/CT imaging has a significant value in preoperative diagnosis and the combination of PTH and CT can improve the positive rate.

ABSTRACT

OBJECTIVES@#To identify the differentially expressed genes (DEGs) during the pathogenesis of periodontitis by bioinformatics analysis.@*METHODS@#GEO2R was used to screen DEGs in GSE10334 and GSE16134. Then, the overlapped DEGs were used for further analysis. g:Profiler was used to perform Gene Ontology analysis and pathway analysis for upregulated and downregulated DEGs. The STRING database was used to construct the protein-protein interaction (PPI) network, which was further visua-lized and analyzed by Cytoscape software. Hub genes and key modules were identified by cytoHubba and MCODE plug-ins, respectively. Finally, transcription factors were predicted via iRegulon plug-in.@*RESULTS@#A total of 196 DEGs were identified, including 139 upregulated and 57 downregulated DEGs. Functional enrichment analysis showed that the upregulated DEGs were mainly enriched in immune-related pathways including immune system, viral protein interaction with cytokine and cytokine receptor, cytokine-cytokine receptor interaction, leukocyte transendothelial migration, and chemokine receptors bind chemokines. On the contrary, the downregulated DEGs were mainly related to the formation of the cornified envelope and keratinization. The identified hub genes in the PPI network were CXCL8, CXCL1, CXCR4, SEL, CD19, and IKZF1. The top three modules were involved in chemokine response, B cell receptor signaling pathway, and interleukin response, respectively. iRegulon analysis revealed that IRF4 scored the highest.@*CONCLUSIONS@#The pathogenesis of periodontitis was closely associated with the expression levels of the identified hub genes including CXCL8, CXCL1, CXCR4, SELL, CD19, and IKZF1. IRF4, the predicted transcription factor, might serve as a dominant upstream regulator.

ABSTRACT

OBJECTIVE@#To evaluate systematically the efficacy and safety of COVID-19 vaccines.@*METHODS@#PubMed, Embase, Cochrane Library, Clinicaltrial.gov, CNKI, Wanfang Data, China Biomedical Literature Service System, and China Clinical Trial Registry were searched for randomized controlled trials of COVID-19 vaccines published up to December 31, 2020. The Cochrane bias risk assessment tool was used to assess the quality of studies. A qualitative analysis was performed on the results of clinical trials.@*RESULTS@#Thirteen randomized, blinded, controlled trials, which involved the safety and efficacy of 11 COVID-19 vaccines, were included. In 10 studies, the 28-day seroconversion rate of subjects exceeded 80%. In two 10 000-scale clinical trials, the vaccines were effective in 95% and 70.4% of the subjects, respectively. The seroconversion rate was lower than 60% in only one study. In six studies, the proportion of subjects who had an adverse reaction within 28 days after vaccination was lower than 30%. This proportion was 30%-50% in two studies and > 50% in the other two studies. Most of the adverse reactions were mild to moderate and resolved within 24 hours after vaccination. The most common local adverse reaction was pain or tenderness at the injection site, and the most common systemic adverse reaction was fatigue, fever, or bodily pain. The immune response and incidence of adverse reactions to the vaccines were positively correlated with the dose given to the subjects. The immune response to the vaccines was worse in the elderly than in the younger population. In 6 studies that compared single-dose and double-dose vaccination, 4 studies showed that double-dose vaccination produced a stronger immune response than single-dose vaccination.@*CONCLUSIONS@#Most of the COVID-19 vaccines appear to be effective and safe. Double-dose vaccination is recommended. However, more research is needed to investigate the long-term efficacy and safety of the vaccines and the influence of dose, age, and production process on the protective efficacy.

ABSTRACT

Objective::To identify and analyze the chemical constituents in Bufei Jianpi formula by UPLC-Q-TOF-MS/MS. Method::An Agilent Poroshell SB-C18 column (4.6 mm×100 mm, 2.7 μm) was used with a mobile phase system of 0.1% formic acid solution (A)-acetonitrile (B) for gradient elution (0-10 min, 3%B; 10-100 min, 3%-50%B; 100-120 min, 50%-100%B) under positive ion mode and water (A)-acetonitrile (B) for gradient elution (0-5 min, 3%B; 5-60 min, 3%-100%B) under negative ion mode, the flow rate was 0.6 mL·min-1, and the column temperature was 30 ℃. Mass spectrometric data were obtained under electrospray inoization (ESI) in positive and negative ion modes, the collection range was m/z 50-1 000.Agilent MassHunter Qualitative Analysis software was used to extract and match chromatographic peaks. Result::Combined with reference, related literature and database analysis, 95 compounds were identified by mass spectrometry information, including 41 flavonoids, 23 alkaloids, 12 lignans, 9 organic acids, and 10 other compounds. Conclusion::The chemical composition of Bufei Jianpi formula is complex, and the cracking rules of different components are different. Flavonoids are prone to deglycosylation, dehydration, Diels-Alder reaction (RDA) cleavage of the ring during lysis, and loss of some neutral molecules such as CO, CO2, CHO. Lignans has a substituent such as a hydroxyl group, a carbonyl group or a methoxy group on the benzene ring, and it is easy to obtain a fragment ion which loses H2O or CO. The basic structure of organic acids is a phenolic hydroxyl group-substituted aromatic ring, acrylic acid, fatty acid or the like, this kind of compound is easy to lose H2O and COOH in negative ion mode, and it is easy to break at the carbonyl to form fragment ions. This established method is rapid, sensitive and accurate, which can quickly identify the chemical constituents in Bufei Jianpi formula and provide evidences for clarifying efficacy material base of this formula.

ABSTRACT

Objective:To improve the quality standard of Shenwei Gubi tablets, and to explore the reasons for the great difference in the contents of quality control index components between batches of this product. Method:The fingerprint of this product was established by HPLC, the determination was performed on Diamonsil C18 column (4.6 mm×250 mm, 5 μm) with acetonitrile (A)-0.1% phosphoric acid solution (B) for gradient elution (0-5 min, 10%A; 5-15 min, 10%-12%A; 15-30 min, 12%-26%A; 30-43 min, 26%-31%A, 43-50 min, 31%-40%A, 50-70 min, 40%-55%A; 70-84 min, 55%-72.5%A) as the mobile phase at detection wavelength of 230 nm. The orthogonal partial least squares-discriminant analysis-variable importance in the projection (OPLS-DA-VIP) map was drawn with the common peak as the independent variable. The contribution of 26 common peaks to the fingerprint differences among different batches of this product was quantified. By searching for the chromatographic peaks with great differences, combined with relevant literature, the components related to the clinical indications of the product were screened out and their contents were determined by specificity experiment, and the quantitative indicators were finally selected. HPLC-doide array detector (DAD) was employed to determine the contents of the above preferred indexes with detection wavelengths of 236, 276, 230, 322 nm, other conditions were the same as HPLC fingerprint detection method. Result:A total of 26 common peaks were calibrated on the HPLC fingerprint of Shenwei Gubi tablets. The similarity between the fingerprint of each batch samples and the reference fingerprint was≥0.950. Loganic acid, gentiopicroside, paeoniflorin and osthole were optimized as the quantitative indicators of this product, their average contents were 161.02, 401.80, 255.54, 80.68 μg·g-1. Conclusion:The established fingerprint and multi-index quantitative analysis method are stable and reliable, and can be used for quality control of Shenwei Gubi tablets. Difference in contents of quality control components between batches of raw materials and the imperfect quality control method of intermediates in the production process are the main reasons for the great difference in the contents of quality control indicators between batches of this product.

ABSTRACT

Objective::To observe the clinical efficacy of Longdan Xiegantang in the treatment of pelvic inflammatory infertility with damp-heat phlegm and phlegm, in order to explore its mechanism of action. Method::Totally 150 patients with phlegm and inflammatory pelvic inflammatory infertility admitted to First Hospital of Hunan University of Chinese Medicine from January 2017 to December 2018 were enrolled in the study. According to the random number, the patients were divided into control group and observation group, with 75 cases in each group. Control group was given antibiotics combined with Gandan Shuangqing granule, and observation group was given Longdan Xiegantang combined with antibiotics. Both groups were treated for 6 weeks. The clinical efficacy, traditional Chinese medicine (TCM) syndrome scores, blood rheology and serum biochemical parameters, inflammatory factor levels and immune function indexes of the two groups were compared. Result::The total effective rate of observation group was 93.33%, which was higher than 78.67% of control group (χ2=6.480, P<0.05). The pregnancy rate of observation group was 58.33%, which was significantly higher than 33.82% of control group (χ2=8.862, P<0.01). Before treatment, there was no significant difference in TCM syndrome score, hemorheology, serum biochemical index, inflammatory factor level and immune function between the two groups. Compared with before treatment, the TCM syndrome scores of lower abdominal pain, anal bulge, lumbosacral pain, abnormal bandage and menstrual disorders were significantly reduced, the levels of plasma viscosity, hematocrit, high and low-shear whole blood viscosity were significantly reduced, the level of inhibin-A (INH-A) was significantly increased, the level of progesterone (P) and beita chorionic gonadotropin (β-HCG) were significantly reduced, the levels of serum C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were significantly decreased, the levels of CD4+ and CD8+ were significantly increased, and the levels of IgA, IgG and IgM were significantly decreased (P<0.05). After treatment, in observation group, TCM syndrome scores of the lower abdominal pain, anal bulge, lumbosacral pain, abnormal bandage and menstrual disorders were significantly reduced, the levels of plasma viscosity, hematocrit, high and low-shear whole blood viscosity were significantly reduced, the level of INH-A was significantly increased, and the level of P and β-HCG were significantly reduced, the levels of serum CRP, IL-6, TNF-α were significantly decreased, the levels of CD4+ and CD8+ were significantly increased, and the levels of IgA, IgG and IgM were significantly decreased (P<0.05). There was no obvious adverse reaction in two groups during the treatment. Conclusion::Longdan Xiegantang has a good clinical effect in treating pelvic inflammatory infertility with damp-heat phlegm and phlegm, and can reduce TCM syndrome scores, and increase pregnancy rate. The mechanism may be correlated with the improvement of blood rheology and serum biochemical indicators, the inhibition of inflammatory factors and the enhancement of immune function.

ABSTRACT

Objective:To retrospectively analyze the clinical characteristics of patients with coronavirus disease 2019 (COVID-19) accompanied with diarrhea.Methods:From January 11 to February 6 in 2020, the clinical data of 663 patients diagnosed with COVID-19 admitted to Renmin Hospital of Wuhan University were collected and divided into diarrhea group and non-diarrhea group according to whether they had diarrhea or not. The differences in baseline characteristics, basic disease history, clinical manifestations, chest computed tomography (CT), laboratory findings, disease severity and mortality between the two groups were compared. Chi-square test and Fisher exact test were used for statistical analysis.Results:Among 663 COVID-19 patients, 70 (10.6%) patients accompanied with diarrhea. The proportion of fatigue and increased lactate dehydrogenase (LDH) levels of diarrhea group were higher than those of non-diarrhea group (58.6%, 41/70 vs. 28.2%, 167/593; and 64.2%, 43/67 vs. 50.4%, 277/550), and the differences were statistically significant ( χ2=26.891 and 4.566, both P<0.05). There was no statistically significant difference in the proportion of pneumonia in chest CT between diarrhea group and non-diarrhea group (100.0%, 62/62 vs. 99.4%, 529/532) ( P>0.05). There were no statistically significant differences in the proportions of mild and normal type, severe type and critical type between diarrhea group and non-diarrhea group (35.7%, 25/70 vs. 38.6%, 229/593; 50.0%, 35/70 vs. 47.2%, 280/593; and 14.3%, 10/70 vs. 14.2%, 84/593, respectively) (all P>0.05). There were no statistically significant differences in the mortality of mild and normal type, severe type and critical type between diarrhea group and non-diarrhea group (0 vs. 0.5%, 3/593; 0 vs. 0 and 1.4%, 1/70 vs. 3.5%, 21/593) (all P>0.05). Conclusions:Patients with COVID-19 accompanied with diarrhea are more likely to have fatigue and increased LDH level. Diarrhea is not significantly correlated with the disease severity of patients with COVID-19.

ABSTRACT

Objective:To compare the different follow-up methods on compliance and prognosis of non-selective beta blockers (NSBBs) for out-patients with secondary prevention of esophagogastric variceal bleeding (EGVB).Methods:A total of 72 patients with portal hypertension and esophageal gastric varices (EGV), who were admitted to the department of gastroenterology, Renmin Hospital of Wuhan University from July 2018 to April 2019 were randomly included in the traditional outpatient follow-up group (group A, 24), remote platform follow-up group (group B, 23) and combined follow-up group (group C, 25) according to the random number table. The patient′s medication compliance, heart rate response, condition change and treatment were recorded. NSBBs medication compliance, influencing factors and prognosis of patients in different groups were analyzed.Results:Forty (40/72, 55.6%) patients had good compliance with NSBBs, among which 34 (34/40, 85.0%) achieved heart rate response. The medication compliance of the group B (15/23, 65.2%) and the group C (17/25, 68.0%) was higher than that of the group A (8/24, 33.3%; χ2=4.778, P=0.029; χ2=5.889, P=0.015, respectively). There was no significant difference in the medication compliance between the group B and the group C ( χ2=0.042, P=0.838). In the group A, the subgroup of good compliance had higher proportion of local patients than that of poor compliance subgroup [7/8 VS 37.5% (6/16), P=0.033]. Patients with good drug compliance had higher proportion of gastroscopy review than that of poor compliance patients [75.0% (30/40) VS 21.9% (7/32), χ2=20.085, P<0.001] and less patients with EGVB [5.0% (2/40) VS 21.9% (7/32), P=0.073]. Conclusion:Patients with portal hypertension and EGV have poor compliance with NSBBs. Remote platform follow-up is a better way to improve compliance of drug prevention. Patients with good NSBBs compliance have a higher compliance of gastroscopy review. The risk assessment of variceal bleeding and endoscopic sequential therapy based on the results of gastroscopy review are expected to reduce the risk of EGVB.
