Metabolic dysfunction-associated fatty liver disease （MAFLD） progresses to metabolic dysfunction-associated steatohepatitis （MASH） due to mitochondrial homeostasis imbalance and dysfunction in hepatocytes caused by various factors such as lipotoxicity and inflammatory infiltration. Recent studies have confirmed that mitochondrial injury is closely associated with chronic inflammation， with extracellular vesicle （EV） acting as a key mediator linking the two processes. This article systematically reviews the molecular mechanisms of hepatocyte mitochondrial dysfunction in MAFLD/MASH， highlights the regulatory role of hepatocyte-derived EV in intrahepatic inflammation， and discusses the potential application prospects of mitochondria-targeted therapies and intercellular communication interventions in MAFLD/MASH， in order to provide a theoretical basis for developing novel therapeutic strategies for these diseases.

Ovarian cancer （OC） is a common gynecological malignant tumor in clinical practice. In the early stage，it is often asymptomatic，while in the late stage，it mainly presents with non-specific symptoms such as abdominal distension，poor appetite，and dull abdominal pain. Some patients may also have cachexia such as weight loss and anemia. Early diagnosis is difficult，and the mortality rate ranks first among gynecological malignant tumors，making OC a major challenge in clinical treatment. The classic Chinese medicine formula Guizhi Fulingwan comes from the Jingui Yaolue and has the effects of promoting blood circulation，removing blood stasis，and reducing abdominal lumps. In recent years，it has been widely used to treat OC with good results. This article summarized the clinical application of Guizhi Fulingwan in the treatment of OC from two aspects：The analysis of its basic prescriptions and clinical research. In terms of basic prescriptions，the formula has the ability to promote blood circulation，remove blood stasis，and reduce abdominal lumps. It can exert therapeutic effects considering both water and blood aspects and reduce abdominal lumps， with characteristics of simultaneous Yang warming and heat clearing and parallel supplementation and elimination. Through the methods of "circulation" and "supplementation"， it strengthens the body，dispels evil，and eliminates underlying symptoms. In clinical studies，Guizhi Fulingwan can be applied to various stages of patients with OC，which not only promotes the recovery of the body after OC surgery but also can be combined with chemotherapy and immunotherapy to synergistically treat advanced OC and enhance treatment efficacy. In addition，the formula can also alleviate various adverse reactions caused by chemotherapy，with high safety，improve patients' quality of life，prolong survival，and optimize tumor control effects. Based on the above analysis，this article elaborated on the current clinical research status of Guizhi Fulingwan combined with Western medicine in the treatment of OC and proposed suggestions and improvements to address the shortcomings in current clinical research，so as to provide reference for the clinical application of this formula in the treatment of OC and the construction of a combined traditional Chinese and Western medicine treatment model.

Objective To evaluate the angiogenesis of decidua in spontaneous abortion patients and to investigate the change of thyroid hormone receptor signal expression in decidua in miscarriage patients.Methods The decidua of pregnant women was collected.Patients with miscarriage were taken as the experimental group and healthy preg-nant women who underwent abortion by social factors were taken as the control group.The nuclear translocation of thyroid hormone receptor α(THR-α)and THR-β in decidua tissues was detected by Western blot method,and the distribution of THR-α and TH IR-β in decidua tissues was determined by immunohistochemistry.The expression of Deiodinase 2(DIO2)in decidua tissues was determined by Western blot.The distribution of DIO2 in decidua tissues was determined by immunofluorescence and the fluorescence intensity was measured.The decidual vessel density was determined by immunohistochemistry using CD34 as an endothelial marker.The protein expression of vascular endothelial growth factor receptor(VEGFR-1)was detected by Western blot.Results There was no sig-nificant difference in age,gestation days,TSH,T3,T4 and other basic data between the control group and the a-bortion group.The results of Western blot showed that the expression levels of THR-α and THR-β protein de-creased,and the results of immunohistochemical staining of decidual tissues showed that the nuclear translocation of decidual thyroid hormone receptor in patients with spontaneous abortion decreased(P＜0.05).Western blotting results showed that the expression of DIO2 protein in the abortion group was lower than that in the control group,suggesting that thyroid hormone metabolism in decidua of spontaneous abortion pregnant women was affected.The results of immunofluorescence test showed that the fluorescence intensity of DIO2 in the abortion group was weaker than that in the control group(P＜0.05).Immunohistochemical CD34 labeling of decidual small blood vessels showed that the number of CD34+blood vessels decreased in the abortion group with statistical difference(P＜0.05).Western blot results showed that there was no significant change in VEGFR-1 between the two groups,and the difference between the two groups was not statistically significant.Conclusion The abnormal signal of thyroid hormone receptors in decidua may decrease decidua angiogenesis and participate in spontaneous abortion.

The intracellular parasite Babesia microti is among the most significant species causing human babesiosis and is an emerging threat to human health worldwide. Unravelling the pathogenic molecular mechanisms of babesiosis is crucial in developing new diagnostic and preventive methods. This study assessed how priming with B. microti surface antigen 1 (BHSA 1) and seroreactive antigen 5-1-1 (BHSA 5-1-1) mediate protection against B. microti infection. The results showed that 500 µg/ml rBMSA1 and rBMSA5-1-1 partially inhibited the invasion of B. microti in vitro by 42.0 ± 3.0%, and 48.0 ± 2.1%, respectively. Blood smears revealed that peak infection at 7 days post-infection (dpi) was 19.6%, 24.7%, and 46.7% in the rBMSA1, rBmSA5-1-1, compared to the control groups (healthy mice infected with B. microti only), respectively. Routine blood tests showed higher white blood cell, red blood cell counts, and haemoglobin levels in the 2 groups (BMSA1 and BMSA5 5-1-1) than in the infection control group at 0–28 dpi. Moreover, the 2 groups had higher serum interferon-γ, tumor necrosis factor-α and Interleukin-17A levels, and lower IL-10 levels than the infection control group throughout the study. These 2 potential vaccine candidate proteins partially inhibit in vitro and in vivo B. microti infection and enhance host immunological response against B. microti infection.

Objective To observe vancomycin and vancomycin in elderly patients with renal toxicity.Methods 105 cases because of infection from March 2013 to October 2014 were collected and randomly divided into two groups, one had 52 patients and were given vancomycin for anti-infection treatment, another group had 53 patients and were given norvancomycin for anti-infective treatment.Changes of serum urea nitrogen and creatinine levels and adverse reactions were observed and compared between two groups.Results Creatinine levels of patients with vancomycin group after 10 days and 7 days after withdrawal were (97.86 ±8.27)μmoI/L, (82.03 ±5.72)μmoI/L, and the norvancomycin group were (98.67 ±8.34)μmoI/L, (83.47 ± 5.91)μmoI/L, the difference were not significant.Urea nitrogen levels of patients with vancomycin group after 10 days and 7 days after withdrawal were (6.71 ±1.15)mmoI/L,(6.09 ±1.09)mmoI/L, respectively, and the norvancomycin group were(6.75 ±1.17)mmoI/L,(6.15 ±1.12)mmoI/L, the difference were not statistically significant.The total effective rate of vancomycin group was 78.85%, and norvancomycin group was 75.47%, the difference was not statistically significant.Adverse reactions of vancomycin group during treatment was 13.46%, and norvancomycin group was 13.21%, the difference was not statistically significant.Conclusion Vancomycin and norvancomycinboth have anti-infective effect on renal function in patients with certain adverse effects, urea nitrogen, creatinine levels in two groups were elevated during treatment, but decreased after withdrawing medicine.

OBJECTIVETo establish a HPLC method to determine the content of aromadendrin in Euonymus alatus.
