Objective Bevacizumab has been clinically used in colorectal cancer,ovarian cancer,cervical cancer,non-small cell lung cancer and other tumor diseases.Common adverse reactions during bevacizumab treatment include albuminuria,thrombosis,bleeding,gastrointestinal perforation and hypertension,among which the incidence of hypertension is as high as 19％-47％.The occurrence of hypertension affects the quality of life of patients,hinds the normal development of tumor treatment,and even induces serious cardiovascular diseases and increases the risk of death,which requires clinical attention.In this paper,the mechanism,influencing factors,prognosis and related treatment of bevacizumab associated hypertension were reviewed,so as to provide reference for clinical rational drug use.

Interventions for endometriosis(EMs)include surgical excision of lesions and hormonal therapy,which usually have limited efficacy and adverse drug reactions.Traditional Chinese medicine(TCM)has the multi-component and multi-target characteristics,which can help patients achieve good clinical benefits by intervening in different parts of the disease.In this paper,we briefly discuss the modern pharmacology of Sanlang and Curcuma longa,and deeply summarize the possible mechanisms of action of TCM monomer and classical compound extracts and their active ingredients through signal pathways in inflammation,immune system,angiogenesis,hormone regulation,etc.,so as to provide theoretical bases for the clinical use of TCM monomers,drug-to-drug groups and compounds in the treatment of EMs.

One patient was admitted to a hospital due to"sepsis,chronic kidney disease,type 2 diabetes,shock,and cerebral infarction".Patient's blood specimen was taken for clinical examination.Aerobic and anaerobic culture results of catheter blood and venous blood were both positive.The pathogen was identified as Staphylococcus pas-teuri by VITEK MS,and the patient was diagnosed as catheter-related bloodstream infection caused by Staphylo-coccus pasteuri.Clinical empirical use of piperacillin for anti-infection treatment was ineffective,and vancomycin was eventually used for treatment based on in vitro antimicrobial susceptibility testing.Patient's condition improved after removing the venous catheter.There are currently no reported cases of Staphylococcus pasteuri in China.Ear-ly identification of pathogen and adjustment of treatment plans based on antimicrobial susceptibility testing results are crucial for effective treatment of this case.

Aortic valve stenosis,as a common heart valve disease,progresses rapidly and has a poor clinical prognosis.In the case of combined acute heart failure,the pumping function of the heart is severely impaired,which may lead to a significant decrease in cardiac output,resulting in a state of shock.Transcatheter aortic valve replacement(TAVR)has become a first-line treatment for elderly patients with aortic valve stenosis since its first successful case in 2002.In China,with the advancement of technology and the strengthening of physician training,the capacity of grassroots hospitals in TAVR treatment is increasing.This case reports a patient with severe aortic valve stenosis accompanied by acute heart failure and shock status who received emergency TAVR treatment at a grassroots hospital.Due to limitations in conditions,TAVR was urgently implemented without extracorporeal circulation and extracorporeal membrane oxygenation support.The patient's blood pressure immediately rose to 105/65 mmHg after valve dilation during surgery,and the postoperative symptoms were significantly relieved.Follow up color Doppler ultrasound showed that the stenosis was relieved and the heart function was significantly improved.The success of this surgery provides a reference for emergency TAVR treatment in patients with severe aortic valve stenosis and heart failure in grassroots hospitals.

The genomic island(GI)characteristics and virulence factor differences of clinical isolates of Burkholderia pseudomallei in Hainan Province,China were analyzed to provide a scientific basis for diagnosis and treatment of melioidosis.In total,52 B.pseudomallei isolates were collected for detection of virulence-related GIs by PCR.The whole genome sequence annotation format file was submitted on Islandviwer 4 platform,and the genomes of the same species and close relatives were added for comparison.Two algorithms,SIGI-HMM and IslandPath-DIMOB,were integrated to predict GIs and sequence a-lignments were conducted to identify specific GIs and differences in virulence factors.The genomes of 52 clinical strains could be divided into three branches based on evolutionary distance,with 82.69％(43/52)of strains concentrated in branch 1.In to-tal,828 GIs were identified among the 52 B.pseudomallei genomes,which formed 157 GI clusters based on sequence similari-ty.GIs accounted for 2.05％-6.38％of the genome content.While GI clusters 1 and 2 were present in all strains,a total of 84(53.50％)GI clusters only clustered within a single genome isolate.Of 10 GI likely specific clusters,five were from the same genus,two from another genus,and three with uncertain origins.Moreover,25 GI clusters were associated with virulence,which included eight shared by B.pseudomallei BP76 and BP169,which had the highest number of virulence-associated GIs among all isolates.O the 52 B.pseudomallei isolates,variations were identified in the virulence genes fhaB1,fhaB2,BPSL1661,cheY1,wzM,tssH-5/clpV,tssA-5,boaA,and boaB.Comparisons of these findings with clinical isolates from Thailand and Australia showed that B.pseudomallei isolates from Hainan had significant differences in the sequences of boaA,boaB,cheY1,and chbp.Additionally,fhaB1,fhaB3,and bimA displayed significant variations specifically within the Australian isolates.B.pseudomallei GI was conserved and specific to Hainan.The identification of specific GI and virulence factors was useful to clarify the source of horizontal gene transfer and differences in virulence at the molecular level.

Objective To investigate the effects of sodium-glucose cotransporter 2 inhibitor (SGLT2i)canagliflozin and epithelial sodium channel inhibitor amiloride or benzamil in combination on the bone metabolism in the rats with the nephrotic syndrome (NS) induced by doxorubicin. Methods In the 49 male SD rats selected, 7 were randomly selected as control group (NG), and 42 were built as adriamycin-induced nephropathy model by injecting adriamycin through the tail vein, and were randomly divided into model group (MG group), canagliflozin group (KG group), benzamil group (BH group), amiloride group (AL group), canagliflozin+benzamil group (KB group) and canagliflozin+amiloride group (KA group), with 7 cases in each group. Each medication group was given intragastric administration according to the body weight of rats regularly every day, NG group and MG group were given equal amount of normal saline, the course of treatment was 6 weeks. The 24-hour urinary protein (24 h-UTP) of each group was detected one day before treatment to verify the successful preparation of the model. At 6 weeks after treatment, the 24 h-UTP, urine sodium (UNa), urinary potassium (UK) levels in urine and the albumin (ALB), triglyceride (TG), cholesterol (TC), low density lipoprotein (LDL), serum calcium (SCa), sodium (SNa), potassium (SK), 25-hydroxyvitamin D (25-OH-D), alkaline phosphatase (ALP), parathyroid hormone (PTH), procollagen type Ⅰ N-terminal propeptide (PINP) and beta C-terminal cross-linked telopeptides of typeⅠ collagen (β-CTX) levels in serum were measured, respectively. Results After successful modeling, the levels of 24 h-UTP, TG, TC, LDL and SCa in the MG group were significantly increased, while the levels of ALB, 25-OH-D, ALP, PINP and PTH were significantly decreased (P < 0.05 or P < 0.01). After 6 weeks of drug intervention, the body mass of rats treated with KG alone decreased significantly (P < 0.05). Compared with the MG group, the levels of 24 h-UTP, TC, TG, LDL and SCa were significantly decreased, and the level of ALB was significantly increased in all drug groups when compared to the MG (P < 0.05 or P < 0.01). Compared with the MG group, the levels of 25-OH-D, ALP, PINP and β-CTX in the KA group were significantly increased when compared to the MG (P < 0.05 or P < 0.01). Molding and drug therapy had no impact on levels of UNa, UK, SK and SNa (P>0.05). Conclusion Calaglizin alone, benzamil alone, amiloride alone and calaglizin combined with benzamil or amiloride can improve the mass proteinuria, hypoproteinemia and hyperlipidemia in adriamycin-induced NS model rats. The combination of caraglipzin and amiloride has a significant osteogenic or osteoclastic effect, which may play a role in reducing the risk of fracture in NS rats by forming a new osteogenic/osteoclastic balance.

Both anti-glomerular basement membrane (GBM) disease and the anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are common causes of pulmonary-renal syndrome. Organizing pneumonia (OP), a special pattern of interstitial lung disease, is extremely rare either in AAV or anti-GBM disease. We report an old woman presented with OP on a background of co-presentation with both ANCA and anti-GBM antibodies.

OBJECTIVE: To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). METHODS: From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12. RESULTS: In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred. CONCLUSIONS GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI. (Registration No. ChiCTR1800014291).

In acute lung injury, two subsets of lung macrophages exist in the alveoli: tissue-resident alveolar macrophages (AMs) and monocyte-derived alveolar macrophages (MDMs).However, it is unclear whether these 2 subsets of macrophages have different functions and characteristics during the recovery phase. RNA-sequencing of AMs and MDMs from the recovery period of LPS-induced lung injury mice revealed their differences in proliferation, cell death, phagocytosis, inflammation and tissue repair. Using flow cytometry, we found that AMs showed a higher ability to proliferate, whereas MDMs expressed a larger amount of cell death. We also compared the ability of phagocytosing apoptotic cells and activating adaptive immunity and found that AMs have a stronger ability to phagocytose, while MDMs are the cells that activate lymphocytes during the resolving phase. By testing surface markers, we found that MDMs were more prone to the M1 phenotype, but expressed a higher level of pro-repairing genes. Finally, analysis of a publicly available set of single-cell RNA-sequencing data on bronchoalveolar lavage cells from patients with SARS-CoV-2 infection validated the double-sided role of MDMs. Blockade of inflammatory MDM recruitment using CCR2 −/− mice effectively attenuates lung injury. Therefore, AMs and MDMs exhibited large differences during recovery. AMs are long-lived M2-like tissue-resident macrophages that have a strong ability to proliferate and phagocytose. MDMs are a paradoxical group of macrophages that promote the repair of tissue damage despite being strongly pro-inflammatory early in infection, and they may undergo cell death as inflammation fades. Preventing the massive recruitment of inflammatory MDMs or promoting their transition to pro-repairing phenotype may be a new direction for the treatment of acute lung injury.

AIM: To investigate the application value of Worst lacrimal probe combined with modified lacrimal duct intubation in anastomosis of complex canalicular laceration.METHODS: Retrospective study. A total of 68 cases(68 eyes)with complex traumatic canalicular laceration treated in the ophthalmology department of the Second Affiliated Hospital of Zunyi Medical University from March 1, 2019 to March 31, 2021 were selected. They were divided into two groups according to the surgical methods, with 36 patients(36 eyes)who were treated with the Worst lacrimal probe to find the broken end of lacrimal duct combined with improved lacrimal duct threading intubation in group A, and 32 patients(32 eyes)who were treated with microscope to find the broken end of lacrimal duct and two-way intubation anastomosis canaliculus intubation in group B. The clinical efficacy, success rate of intraoperative search for the broken end of lacrimal duct, searching time, operation time, the degree of pain, postoperative ocular foreign body sensation and complications were compared between the two groups.RESULTS: The total effective rate of clinical efficacy in patients of group A was higher than that in group B(94% vs. 38%), the success rate of intraoperative search for broken end of lacrimal duct was higher than that in group B(100% vs. 47%), the searching time and operation time were shorter than those in group B, and the score of pain degree was lower than that in group B(all P<0.05). The postoperative follow-up for 6mo-1a showed that the ocular foreign body sensation score, the incidence of lacrimal punctum rupture and morphological change, and the degree of tear overflow in group A were all lower than those in group B(all P<0.05).CONCLUSION: Worst lacrimal probe combined with modified lacrimal duct intubation for the treatment of complex traumatic canalicular laceration can find the broken end of lacrimal duct more accurately, shorten the operation time, reduce the pain and foreign body sensation of patients, improve clinical efficacy and reduce the incidence of complications.
