Acute myocardial infarction and acute upper gastrointestinal bleeding are both critical internal medicine conditions. The incidence of acute upper gastrointestinal bleeding in patients with acute myocardial infarction ranges from 5.31% to 8.90%, with a mortality rate as high as 20.50% to 35.70%. The pathogenesis may be related to the use of antiplatelet and anticoagulant drugs, as well as stress-induced injury. In treatment, the contradiction between antiplatelet/anticoagulation therapy and bleeding has made this disease a significant challenge in modern medicine. Therefore, re-exploring the etiology, pathogenesis, treatment principles, and methods of traditional Chinese medicine(TCM) for acute myocardial infarction and acute upper gastrointestinal bleeding is of great clinical importance. The research team has been working year-round in the coronary care unit(CCU), managing a large number of such severe patients. By revisiting classic texts and delving into the foundational theories of TCM and historical medical literature, it has been found that this disease falls under the category of "distant blood" in the Synopsis of the Golden Chamber. In terms of etiology, it is primarily associated with weakness of healthy Qi and damage caused by drug toxicity. In terms of pathogenesis, in the acute stage, it mainly manifests as insufficient spleen Yang, deficiency of spleen Qi, and failure of the spleen to control blood. In the remission stage, it is characterized by deficiency of both heart Qi and spleen blood. For treatment, during the acute stage, Huangtu Decoction is used to warm Yang and restrain blood, while in the remission stage, Guipi Decoction is administered to tonify Qi and nourish blood. During the treatment process, for patients with acute myocardial infarction complicated with acute upper gastrointestinal bleeding, it is crucial to flexibly apply the treatment principles of "Nil per os" in western medicine and "where there is stomach Qi, there is life; where there is no stomach Qi, there is death" in TCM. Early intervention with Huangtu Decoction can also prevent bleeding, with large doses being key to achieving hemostasis. It is important to address the pathogenesis of heat syndrome in addition to the core pathogenesis of Yang deficiency bleeding and to emphasize the follow-up treatment with Guipi Decoction for a successful outcome.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

BackgroundPrevious studies have shown that hypertension is an important factor contributing to the occurrence and progression of diabetic kidney damage. However, the relationship between the patterns of blood pressure (BP) trajectory and kidney damage in the diabetic population remains unclear. This prospective study investigated the effect of long-term systolic BP (SBP) trajectory on kidney damage in the diabetic population based on an 8-year follow-up community-based cohort.

MethodsThis study included 4556 diabetic participants among 101,510 participants. BP, estimated glomerular filtration rate (eGFR), and urinary protein were measured every 2 years from 2006 to 2014. SBP trajectory was identified by the censored normal modeling. Five discrete SBP trajectories were identified according to SBP range and the changing pattern over time. Kidney damage was evaluated through eGFR and urinary protein value. A multivariate logistic regression model was used to analyze the influence of different SBP trajectory groups on kidney damage.

ResultsWe identified five discrete SBP trajectories: low-stable group (n = 864), moderate-stable group (n = 1980), moderate increasing group (n = 609), elevated decreasing group, (n = 679), and elevated stable group (n = 424). The detection rate of kidney damage in the low-stable group (SBP: 118-124 mmHg) was the lowest among the five groups. The detection rate of each kidney damage index was higher in the elevated stable group (SBP: 159-172 mmHg) compared with the low-stable group. For details, the gap was 4.14 (11.6% vs. 2.8%) in eGFR <60 ml·min·1.73 m and 3.66 (17.2% vs. 4.7%), 3.38 (25.0% vs. 7.4%), and 1.8 (10.6% vs. 5.9%) times in positive urinary protein, eGFR <60 ml·min·1.73 m and/or positive urinary protein, and eGFR decline ≥30%, respectively (P < 0.01).

ConclusionAn elevated stable SBP trajectory is an independent risk factor for kidney damage in the diabetic population.

To optimize the belt drying process conditions optimization of Gardeniae Fructus extract from Reduning injection by Box-Behnken design-response surface methodology, on the basis of single factor experiment, a three-factor and three-level Box-Behnken experimental design was employed to optimize the drying technology of Gardeniae Fructus extract from Reduning injection. With drying temperature, drying time, feeding speed as independent variables and the content of geniposide as dependent variable, the experimental data were fitted to a second order polynomial equation, establishing the mathematical relationship between the content of geniposide and respective variables. With the experimental data analyzed by Design-Expert 8. 0. 6, the optimal drying parameter was as follows: the drying temperature was 98.5 degrees C , the drying time was 89 min, the feeding speed was 99.8 r x min(-1). Three verification experiments were taked under this technology and the measured average content of geniposide was 564. 108 mg x g(-1), which was close to the model prediction: 563. 307 mg x g(-1). According to the verification test, the Gardeniae Fructus belt drying process is steady and feasible. So single factor experiments combined with response surface method (RSM) could be used to optimize the drying technology of Reduning injection Gardenia extract.

In this study, we used traditional morphological and molecular identification methods to preliminarily identify two strains of dermatophytes. The two strains were observed under the microscope. And then the dermatophytes were cultured on Sabouraud's dextrose agar (SDA). The 18S rRNA regions of the two dermatophyte strains were amplified by polymerase chain reaction (PCR), and the PCR products were sequenced and compared with GenBank data. BLAST tools and DNAMAN software were used to analyze the sequences. To further determine highly homologous sequences, a phylogenetic tree was constructed using the Neighbor-Joining method. The two strains of dermatophytes were identified by traditional morphological identification as Epidermophyton floccosum and Microsporum ferrugineum. The 18S rRNA sequence analyses showed high similarities to Cladosporium cladosporioides isolate C115LM-UFPR and Ascomycete sp. LB68A1A2. Epidermophyton and Cladosporium belong to dermatophyte, while Microsporum ferrugineum and Ascomycete belong to microsporum. The two novel strains of dermatophytes were therefore identified as Cladosporium cladosporioides isolate C115LM-UFPR (JN650537, Cladosporium) and Ascomycete sp. LB68A1A2 (AY770409, Ascomycete sp).

This study was purposed to investigate the clinical features and related factors influencing prognosis of patients with severe intestinal graft-versus-host disease (siGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). 710 patients received allo-HSCT in Beijing Dao-Pei hospital from Jan 2007 to Jan 2011 were enrolled in this study. A total of 34 patients with siGVHD out of 710 patients were analyzed retrospectively, and the univariate analysis for related factors influencing prognosis were carried out by using SPSS 19.0 software. The results showed that the incidence of siGVHD was 4.79%, its medium occurrence time was 29 (18 - 210) days after allo-HSCT. 18 out of 34 patients with siGVHD received colonoscopy, among them 6 patients were complicated with viral enteritis. The deep ulcers could be found under colonoscope. Histopathologic examination revealed the viral inclusion bodies or positive viral antigen. Methylprednisolone (MP), cyclosporine A (CsA) or tacrolimus combined CD25 monoclonal antibody and oral budesonide were used for treatment of siGVHD. 29 out of 34 cases achieved complete response (CR) with CR rate of 85.29%, overall survival rate was 58.82% (20/34). 9 out of 29 cases achieving CR died of other complications. The univariate analysis of the related factor indicated the hyperacute GVHD is the adverse factor influencing overall survival of patients with siGVHD. It is concluded that early colonoscopy is an effective way for definitive diagnosis of siGVHD. The combined treatment including MP, CsA or tacrolimus, CD25 monoclonal antibody and oral budesonide shows a significant curative effects. Intensive treatment of complications in late period of GVHD can enhance the overall survival rate.

OBJECTIVETo analyze the clinical and laboratory features of 9 cases of gammadeltaT cell lymphoma or leukemia.

METHODSFrom 2007 to 2011, 9 patients with gammadeltaT-cell lymphoma/leukemia were diagnosed in our hospital. The immunophenotype of the abnormal cells were detected by flow cytometry, clonal gene rearrangement of IgH, TCRgamma, TCRdelta by PCR, chromosome karyotype analysis by G banding, acute leukemia gene and the DNA of type 1 - 8 human herpes virus by multiple nested PCR, The gammadeltaT cells were determined by T cell with TCR gammadelta chain, the malignant gammadelta T cells by the abnormal expression of T cell antigens and the precursor malignant gammadelta T cells by the expression of CD34, TDT, CD99, CD1 a or acute leukemia genes.

RESULTSIn the 9 patients with gammadeltaT cell lymphoma leukemia, significant malignant gammadeltaT cells infiltration of bone marrow were found in 8 with blast morphology. 5 were diagnosed as T-ALL/LBL (gammadeltaT type) and 4 HSgammadelta TCL. The clonal gene rearrangement of TCRgamma and/or TCRB were detected in 6/6 patients. Patients either did not achieve complete remission(CR) after induction therapy or relapsed quickly after CR. Only 4/5 patients remained continuous CR(CCR) at 2, 2, 3,12 months respectively, after allogeneic hematopoietic stem cell transplantation (allo-HSCT), the fifth T-ALL (gammadeltaT) relapsed 1 month after allo-HSCT.

CONCLUSIONSThe incidence of gammadelta T cell lymphoma or leukemia may be higher than reported, part of them were T-ALL/LBL with poor prognoses. FCM and clonal gene rearrangement of TCRgamma and/or TCRdelta are helpful to diagnosis. Allo-HSCT may be the only curative approach.

The magnetic responsibility and antitumor effect of magnetic gemcitabine stealth nano-liposomes (MGSL) on breast cancer cell line MCF-7 in vitro and in vivo was evaluated. The magnetic response and targeting effect of MGSL in vivo were investigated. Morphological feature and ultrastructure changes of apoptosis of MCF-7 cells were observed. The effect of MGSL on proliferation inhibitory rate of MCF-7 cells was measured with MTT method. The FCM analysis was carried out to examine the cell cycle distribution and cell apoptotic rate. The antitumor effect on human breast cancer xenografts in nude mice was also studied. MGSL was able to converge at the targeting tissue under tridimensional magnetic field and the gemcitabine concentration around it increased, while the amount of gemcitabine in other organs decreased, such as in kidneys and heart. MCF-7 cell line was sensitive to MGSL and the cytotoxity was correlated with the loaded drug dose. The effect of MGSL on apoptosis of MCF-7 was obvious and the rate of apoptosis was 51.62%. The growth speed of tumor in the group of MGSL (+) significantly slowed down than that of other groups. MGSL prepared by reverse-phase evaporation method met with the demand of targeted delivery system, and it might be an effective antitumor agent.
