Radiotherapy,as an important means of tumor treatment,plays a significant role in the treatment of cervical cancer.However,the ovaries are highly sensitive to radiation,which is prone to appear radiation-related injuries,leading to ovarian dysfunction and loss of fertility in young female patients,seriously affecting their physical and mental health.The degree of ovarian injury is influenced by various factors such as the dose,volume,and duration of radiation exposure to the ova-ries,as well as the patient's age.Ovarian displacement and advancements in radiotherapy techniques can significantly relieve radiation-related ovarian injury.Currently,drug protection techniques are still immature,and new fertility preservation methods are receiving increasing attention but require further improvement.This article reviewed the research progress in the molecular mechanisms,pre-vention strategies,and new fertility preservation techniques for ovarian injury related to cervical canc-er radiotherapy,aiming to provide a reference for ovarian function protection during radiotherapy for young cervical cancer patients.

OBJECTIVETo establish the two-dimensional electrophoresis profiles with high resolution and reproducibility from the brain tissues of mice with human cytomegalovirus (HCMV) infection.
METHODSForty Kunming mice were randomized into HCMV infection group (n=20) with HCMVAD(169) injection and control group (n=20) with saline injection in the brain. Thirty days after the injections, the brain tissue of the mice were taken and the protein fractions were isolated by two-dimensional gel electrophoresis (2-DE). Image Master 2D software was used to identify the differentially expressed proteins, and the peptide mass fingerprint (PMF) data were obtained for identification of the differential protein spots via database searching. Western blotting was performed to verify the expressions of some of the differential proteins.
RESULTS AND CONCLUSIONThe 2-D maps of the brain tissues with high Well resolution and reproducibility were obtained. Some of the differentially expressed proteins identified by mass spectrometry (MS) matched their counterparts in the SWISS-2DPAGE database. Western blotting analyses verified the differential expression of the individual proteins. These data can be of value for studying the diagnosis, pathogenesis and effective therapeutic targets of the disease.

AIMTo evaluate the fertilization competence of spermatozoa from ejaculates and testicle when the oocytes were matured in vitro following intracytoplasmic sperm injection (ICSI).
METHODSFifty-six completed cycles in 46 women with polycystic ovarian syndrome were grouped according to the semen parameters of their male partners. Group 1 was 47 cycles that presented motile and normal morphology spermatozoa in ejaculates and Group 2 was the other nine cycles where male partners were diagnosed as obstructive azoospermia and spermatozoa could only be found in testicular tissue fragment. All female patients received minimal stimulation with gonadotropin. Immature oocytes were matured in vitro and inseminated by ICSI. The spermatozoa from testes were retrieved by testicular fine needle aspiration.
RESULTSA total of 449 and 78 immature oocytes were collected and cultured for 48 hours, 75.5 % (339/449) and 84.6 % (66/78) oocytes were matured in Groups 1 and 2, respectively. The percentage of oocytes achieving normal fertilization was significantly higher in Group 1 than that in Group 2 (72.9 % vs. 54.5 %, P 0.05). There were no significant differences in the rates of oocytes cleavage and clinical pregnancies in these two groups [87.4 % (216/247) vs. 88.9 % (32/36); 21.3 % (10/47) vs. 44.4 % (4/9)]. A total of 15 babies in the two groups were healthy delivered at term.
CONCLUSIONIt appears that IVM combined with ICSI using testicular spermatozoa can produce healthy infants, while the normal fertilization rate of in vitro matured oocytes after ICSI using testicular spermatozoa was significantly lower than using the ejaculated spermatozoa.

AIM To explore the clinical effects of Polygonum cuspidatum Sieb.et Zucc.on patients with type 2 diabetes mellitus of Dampness-Heat Pattern.METHODS One hundred and forty patients were randomly assigned into control group(70 cases)for 8-week intervention of conventional treatment,and observation group(70 cases)for 8-week intervention of both P.cuspidatum granules and conventional treatment.The changes in body weight,BMI,blood glucose indices(FBG,2 h PG,HbA1C,GA),blood lipid indices(TC,TG,HDL-C,LDL-C,ApoA-I,ApoB,ApoA,ApoE,sdLDL-C),liver function indices(ALT,AST),fatty liver progression,TyG,HSI,TCM syndrome score and effects were detected.RESULTS The observation group demonstrated higher total effective rates of TCM syndromes than the control group(P<0.01),along with slighter fatty liver progression(P<0.01).After the treatment,the observation group displayed decreased body weight,BMI,FBG,GA,TG,ApoE,TyG,HSI,ALT and TCM syndrome score(P<0.05,P<0.01),and 2 h PG,TyG,HSI,ALT,TCM syndrome score were lower than those in the control group(P<0.05,P<0.01).CONCLUSION For the patients with type 2 diabetes mellitus of Dampness-Heat Pattern,P.cuspidatum can improve glucose and lipid metabolism disorders,which is worthy of clinical popularization and application.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75%(27/36);boys accounted for 64%(23/36).Among the 36 neonates,31(86%)had disease onset within 3 days after birth,and 19(53%)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61%)had left cerebral infarction and 13(36%)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75%)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72%)and seizures in 10 neonates(34%).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33%,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44%(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.
