OBJECTIVETo improve the diagnosis and treatment of penile metastasis from rectal carcinoma.
METHODSWe reported a case of penile metastasis secondary to rectal adenocarcinoma, reviewed the relevant literature, and discussed the common origins, clinical features, pathogenic mechanisms, diagnosis and treatment of this disease.
RESULTSThe patient was a 54-year-old male, with metastatic penile tumors secondary to rectal adenocarcinoma, with serious adhesion to the surrounding tissue and metastasis to the liver. As treatment, we performed colostomy to relieve voiding difficulty, followed by combination chemotherapy with oxaliplatin, 5-fluorouracil, and levofolinate. The patient died 10 months later as a result of systemic failure.
CONCLUSIONPenile metastatic malignancy has a poor prognosis. Early diagnosis and combined and individualized therapies may improve the quality of life, relieve pain and prolong the life of the patient.

Objective To make a further understanding of mammographic features of simple cyst of the breast (SCB).Methods Molybdenum target radiographic signs in 39 cases with SCB proved pathologically and were retrospectively analyzed. Results Of the 56 SCB in 39 cases, 23 were diagnosed rightly as SCB, 10 as fibroadenoma, 2 as cancer and the remaining 4 were undefined. The diagnostic accuracy and misdiagnosis were 59.0% and 41.0% respectively. Radiograph showed round in 12, ovoid in 38, mild lobed in 4 and comet tail form in 2. The borders of cyst were distinct and sharp in 26, distinct partly and indistinct partly in 27,indistinct completely in 3. The density was homogeneous in 54 with calcifications in 2. Of the 56 SCB, the length axes of cyst were upright to chest wall in 20 and towards nipple in 18. The cysts could be transformed with pressure in 4.Conclusion Careful analysis of radiographic features of SCB is helpful for diagnosing accurately this disease.

This study was designed to explore the RNA interference technique in inhibition of the expression of the mouse fibrinogen like protein 2 (mfgl2), which has been reported to be involved in the development a variety of diseases including fulminant viral hepatitis. A plasmid named p-mfgl2shRNA,complementary to the sequence of mfgl2 was constructed, while another short hairpin RNA (shRNA)which was a mutated form of the mfgl2shRNA sequences was used as a control. A plasmid named pEGFP-mfgl2 expressing the mfgl2-EGFP fusion protein was also constructed for the screening of the effect of p-mfgl2shRNA on mfgl2 expression. By cotransfection of p-mfgl2shRNA and pEGFP-mfgl2 or pcDNA3.1-mfgl2 expression construct into CHO cells or HeLa cells, the inhibition of mfgl2 expression by mfgl2shRNA was analyzed by direct observation through fluorescent microscopy, FACS, RT-PCR and immunohistochemistry staining. The experiments showed the significant inhibitory effect of p-mfgl2shRNA on mfgl2 expression at 48h post-transfection in both CHO and Hela cell lines with the inhibitory efficiency as high as 80.1%. The study demonstrated that the construct of p-mfgl2shRNA successfully interfered with the mfgl2 expression in vitro.

OBJECTIVE:
To explore the protective effect of noninvasive limb ischemic preconditioning (N-LIP) on acute lung injury (ALT) induced by lipopolysaccharide (LPS) in rats.
METHODS:
Fifteen female SD rats were randomly divided into a control group, an acute lung injury group (ALI group), an acute lung injury and noninvasive limb ischemic preconditioning group (ALI+N-LIP group). After ALI rats were treated with N-LIP, the changes of airway resistance (AR) and dynamic compliance (Cdyn) were tested by invasive pulmonary function system and recorded. Blood samples and bronchoalveolar lavage fluid (BALF) were collected, the amounts of white blood cell (WBC) in BALF were counted by cytometry, and the level of lactate dehydrogenase (LDH) in BALF was also examined by automatic biochemistry analyzer. The level of serum superoxide dismutase (SOD) and malondialdehyd (MDA) was examined by chromatometry. The lung tissues were acquired to observe the expression of pulmonary surfactant-associated protein-A (SP-A) and pathological changes.
RESULTS:
After being stimulated by methacholine (Mch), the increasing rate of AR and decreasing rate of Cdyn in the ALI+N-LIP group were less than those in the ALI group (P<0.01). The levels of WBC and LDH in BALF in the ALI+N-LIP group were much lower than those in the ALI group (P<0.05). Meanwhile, the activity of serum SOD in the ALI+N-LIP group was higher, and the level of serum MDA was lower than that in the ALI group (P<0.05). The expression of SP-A in the lung tissue in the ALI+N-LIP group was the highest in the 3 groups, while that in the ALI group was the weakest (P<0.01). Injury of the lung tissue in the ALI+N-LIP group was less than that in the ALI group, but more severe than that in the control group.
CONCLUSION
N-LIP has protective effect on acute lung injury induced by LPS in rats. The possible mechanism is related to improving the secretion of SP-A and antioxidation.

In order to establish the stable andreliable ISSR-PCR System of Lysimachia christinae, L16 (4(5)) orthogonal design, which based on 7 levels of single factor experiment, were used in this study. The variance analysis was carried out by SPSS 19.0, and 5 main factors affecting the reaction system were optimized in 4 levels. The best annealing temperature was selected by the optimized reaction system. And the stability and reliability of this system was tested by 23 samples from different origins. The results showed that the five factors (DNA template, primer, dNTP, Mg2+ and Taq enzyme) were the most impacts on the amplified results of ISSR-PCR of L. christinae. The order of the influence was: primer > Taq enzyme > DNA template > Mg2+ > dNTP. The optimal system, which was determined by multiple comparison on different levels of each factor, was total volume of 25 microL, including DNA template 60 ng, primer 0.3 micromol x L(-1), dNTP 0.2 mmol x L(-1), Mg2+ 1.8 mmol x L(-1), Taq enzyme 1.25 U. The optimal system was stable and reliable tested by 23 samples from different origins. This study lays the foundation for genetic diversity analysis, fine varieties selection and molecular identification of L. christinae, and provides reference for optimization on ISSR-PCR system of other speciesin future.

mPem, a homeobox gene, is expressed in a time and stage specific manner during murine ontogeny. Pem transcripts are abundant in 7- and 8-day mouse embryos, but decrease precipitously thereafter. On Day 9 they become abundant in placenta and yolk sac, persisting there until parturition. Although Pem transcripts are not detectable in most of adult tissues, they are present in reproductive system such as testis, epididymis and ovary. This indicates a important role for Pem during embryogenesis and reproductive development. To study the function of mPem protein, we used a GAL4 based yeast two-hybrid assay to screen a 7-day mouse embryo library with full-length of mPem. 3 proteins were found interacting with mPem protein. One of theses is Mdfic. We confirmed the interaction between mPem and Mdfic in yeast and in vitro. Mdfic, MyoD family inhibitor domain containing, encodes the myoD family inhibitor domain (I-mfa domain). The interaction between mPem and Mdfic suggested they maybe form the transcriptional regulator complex to regulate embryo differentiation.

OBJECTIVETo investigate the clinical characteristics of endometrial carcinoma in patients below 45 years of age.
METHODSThe clinical data were collected from 53 patients with endometrial carcinoma below 45 years of age, who were divided into less than 40 year group (group A, 28 cases) and 40 to 45 year group (group B, 25 cases) and their clinical data were compared.
RESULTSA rate of 57.1% (16/28) of the patients in group A were infertile, and 78.5% (22/28) reported irregular menstruation. In group B, the infertility rate was 28.0% (7/25), and 48% (12/25) of the patients were obese, 56% (14/25) had abnormal vaginal bleeding, and 32% (8/25) had diabetes and hypertension. The two groups differed significantly in the infertility rate, number of pregnancies and deliveries and the incidences of obesity, hypertension and diabetes. The pathological classification, grade of differentiation, pathological staging, depth of myometrial invasion, and cervical infiltration status were comparable between the two groups (P>0.05). All the 53 patients received surgical interventions and follow. up for two years, during which 1 patients in group B had relapse.
CONCLUSIONPatients with endometrial carcinoma at 40 years of age or below often have infertility, and those over 40 years are exposed to such high-risk factors as obesity, diabetes, and hypertension. Its major clinical symptom of endometrial carcinoma is menstrual disorders. The differentiation, pathological staging, pathological classification of the malignancy are not associated with age in patients below 45 years of age. Early diagnosis often warrants more favorable prognosis.

Although guidelines and formulas have been developed through clinical practice to define infusion rate and volume, over- and under-resuscitation are still common, followed by increasing morbidity and mortality. In order to establish an effective management for early fluid resuscitation, the clinical decision support system (CDSS) has been established. The CDSS, by utilizing information systems coupled with decision support technology, could provide recommendations for the amount of fluid to be infused based on measured biological response. The results showed that patients treated with CDSS had a significantly lower mortality, increased ventilator-free days, and ICU-free days as compared with those treated with traditional fluid management. This article reviews the concepts as well as the result of recent clinical studies of CDSS for burn patients.

Objective:To investigate the characteristics of executive function of preschool children with high functioning autism spectrum disorder (HFA) and with global developmental delay (GDD), and the differences among HFA, GDD and typically developmental (TD) children.Methods:From January 2020 to January 2021, 20 male HFA, 20 male GDD and 20 male TD children aged 4-6 years who visited the Psychological Behavior Clinic of the Child Health Department of Guiyang Maternal and Child Health Hospital and the Developmental Behavior Clinic of the Children Health Department of the Ninth People's Hospital in Chongqing were selected for comparative study.The executive function of HFA, GDD and TD children was assessed with the behavior rating scale of executive function-preschool version(BRIEF-P) and the executive function task program (EF-TOUCH). SPSS 26.0 software was used for statistical analysis, including variance test, independent sample t-test, χ2 test, Kruskal Wallis test and Mann-Whitney U test. Results:In the EF-TOUCH program task, the accuracy of the three groups of children's performance in the pig task (Pig), the silly sounds game (SSG), the working memory task (pick the picture, PTP) and the task of cognitive flexibility (something's the same, STS) were statistically different(Pig: HFA group: 0.87(0.76, 0.99), GDD group: 0.97(0.85, 0.99), TD group: 1.00(0.98, 1.00), χ2=15.646, P<0.001; SSG: HFA group: 0.76(0.53, 0.91), GDD group: 0.76(0.65, 0.99), TD group: 0.94(0.76, 1.00), χ2=6.448, P=0.040; PTP: HFA group: 0.66±0.18, GDD group: 0.66±0.19, TD group: 0.78±0.11; F=3.221, P=0.048; STS: HFA group: 0.67(0.63, 0.70), GDD group: 0.72(0.46, 0.78), TD group: 0.87(0.83, 0.90), χ2=26.898, P<0.001). The accuracies of Pig, SSG, PTP and STS in HFA group were significantly lower than those in TD group(all P<0.05), and the accuracies of Pig and STS in GDD group were significantly lower than those in TD group(both P<0.05). In inhibition control, there were statistically differences in response time of Pig and SSG among the three groups (Pig: HFA group: (1 694.36±222.83)ms, GDD group: (1 513.46±244.91)ms, TD group: (1 444.84±197.95)ms, F=5.810, P=0.005; SSG: HFA group: (2 202.42±195.58)ms, GDD group: (2 116.52±323.27)ms, TD group: (1 937.17±252.74)ms, Z=4.610, P=0.014). There were no significant differences in the reaction time of Arrows task ( P>0.05). There were significant differences in BRIEF-P inhibition control, organizational planning, inhibition self-regulation, cognitive flexibility and total scores among the three groups ( P<0.05), while there were no significant differences in the scores of other factors and dimensions ( P>0.05). Conclusion:The executive function of pre-school children with high functioning autism spectrum disorder and children with global developmental delay is impaired.The executive function of children with high functioning autism spectrum disorder and children with global developmental delay is significantly different from that of typically developmental children of the same age.Moreover, the executive function of children with HFA is more severely damaged from all components than that of children with GDD.
