OBJECTIVETo investigate the factors influencing the prognosis of penis-sparing surgery (PSS) for early-stage penile cancer.

METHODSWe retrospectively studied the clinical data about 45 cases of early-stage penile cancer treated by PSS from January 2007 to December 2014. We calculated the rate of local recurrence-free survival by the Kaplan-Meier method, and conducted univariate and multivariate COX regression analyses on the relevant factors including the patient's age, marital status, tumor location, tumor size, postoperative sexual life, histological grade, and TNM stage.

RESULTSOne-year and three-year local recurrence-free survival rates were 95.5% and 52.2%, respectively. Multivariate analysis demonstrated that the histological grade (P = 0.039) and postoperative sexual life (P = 0.049) were independent factors for the prognosis of PSS. Logistic regression showed the patients age to be significantly associated with histological grade (P = 0.014).

CONCLUSIONHistological grade and postoperative sexual life are important independent prognostic factors of PSS for early-stage penile cancer, and the patients age is associated with the prognosis of PSS through its influence on the tumor grade.

OBJECTIVETo study the effect of acupuncture on skeletal muscle endurance in rats as a pre-games assistant training.

METHODSThirty male SD rats were randomly divided into 3 groups: control, model and acupuncture group. Acupuncture group was treated at "Dazhui" (GV 14), "Housanli" (ST 36) by twisting mild reinforcing-reducing method for 20 min, no interventions were added on control and model group. Muscle strength was detected in three groups under anaesthetic (after model established in model group, after model established and treated in acupuncture group). Averaged change percentage of mean skeletal muscle endurance (P(m)) and averaged maximum percentage of skeletal muscle endurance (P(max)) were evaluated.

RESULTS(1) 10P(m) in model group decreased more than acupuncture group statistically (P < 0.05); 20P(m), 30P(m) and 40P(m) in model group decreased significantly compared to those in control group and acupuncture group (P < 0.05, P < 0.01). (2) Changes of 10P(max) in acupuncture group was much less than in model group (P < 0.05); changes of 20P(max), 30P(max), 40P(max) and 50P(max) decreased more in model group than in acupuncture group and control group (P < 0.01, P < 0.05).

CONCLUSIONAs an assistant training method, acupuncture can postpone descending point of muscle strength endurance to delay sport fatigue.

OBJECTIVETo investigate the mechanism of the development of cisplatin resistance in a human esophageal squamous carcinoma cell line.

METHODSThe cytotoxicity of cisplatin in the cisplatin-resistant resistant cell line EC109/CDDP and its parental cell line EC109 was measured by MTT assay. Whole-cell cisplatin accumulation and Pt-DNA adduct formation were determined by inductively coupled plasma mass spectrometry (ICP-MS). Western blotting was used to investigate the protein expression of full length PARP, cleaved PARP, and copper transporter 1 (CTR1).

RESULTSEC109/CDDP cells was more resistant to cisplatin-induced cytotoxicity and apoptosis than EC109 cells. Compared with EC109 cells, EC109/CDDP cells exhibited less cisplatin accumulation and Pt-DNA adduct formation with also decreased CTR1 protein expression.

CONCLUSIONCisplatin induces drug resistant phenotype by decreasing the protein level of CTR1, which controls cell accumulation and cytotoxic effect of cisplatin.

OBJECTIVETo analyze the distribution of the musculoskeletal disorders, work load and working postures in different factories, gender, education levels, age and working years among manufacturing workers.

METHODSIn a cross-sectional study of 5134 manufacturing workers in 12 factories, the morbidities for musculoskeletal disorders in one year period were measured with questionnaires.

RESULTSThe morbidities for musculoskeletal disorders in body sites: waist, neck, shoulder, wrist, ankle/feet, knee, hip/buttocks and elbows were 59.7%, 47.9%, 38.1%, 33.7%, 26.9%, 25.4%, 15.2%, and 14.9%, respectively in one year period. There were significant differences of morbidities for musculoskeletal symptoms in body sites of workers among different factories (P < 0.05 or P < 0.01). The morbidities of musculoskeletal symptoms in elbows, waist, wrists and ankle/feet of the workers in refractory material and chemical fiber factories were higher than those in other factories, the morbidities for musculoskeletal symptoms of workers in garments and diamond factories were lower than those in other factories. The morbidities for musculoskeletal symptoms in neck, shoulders and wrists of female workers were significantly higher than those of male workers (P < 0.01). There were significant differences of the morbidities for musculoskeletal symptoms in body sites among workers with different educational levels (P < 0.05 or P < 0.01). There were significant differences of the morbidities for musculoskeletal symptoms in neck, shoulders, wrists, hip/buttocks and knee among groups with different age or different working years (P < 0.01), and the morbidities for musculoskeletal symptoms increased with age and working years. The proportions of unhealthy working postures and high working load among workers in refractory material and chemical fiber factories were higher; but those in garments and diamond factories were lower.

CONCLUSIONThe morbidities for musculoskeletal symptoms in waist, neck, shoulder and wrists of workers in manufacturing workers were higher; the gender, education level, age and working years could influenced the morbidities for musculoskeletal disorders.

OBJECTIVETo study the application value of normal sperm morphology on the outcomes of classic in vitro fertilization and embryo transfer (IVF-ET).

METHODSThis study included 659 infertile couples admitted to our center for IVF-ET. Based on the percentage of morphologically normal sperm (MNS), we divided the patients into groups A (n = 112, MNS < 2%), B (n = 180, MNS > or = 2 - < 4%), C (n = 74, MNS > or = 4 - < 5%), and D (n = 293, MNS > or = 5%), and compared the rates of fertilization, normal fertilization, embryos obtained, biochemical pregnancy, clinical pregnancy, implantation, and live birth among different groups.

RESULTSThe mean fertilization rate was significantly higher in groups C (71.90%) and D (72.89%) than in A (57.97%) and B (63.29%) (P < 0.05), with no remarkable differences either between A and B (P > 0.05) or between C and D (P > 0.05). The normal fertilization rate was also significantly higher in group D (57.16%) than in A (46.52%) and B (50.89%) (both P < 0.05) as well as in C (54.67%) than in A (P < 0.05). The rate of embryos obtained, too, was markedly higher in group D (55.62%) than in B (45.75%) (P < 0.05), but none with remarkable difference from other groups (all P > 0.05). There were no statistically significant differences among the four groups in the rates of biochemical pregnancy, clinical pregnancy, implantation, abortion, and live birth (all P > 0.05).

CONCLUSIONThe rate of MNS had some influence on IVF-ET, and 5% MNS exhibited a higher value than 4% MNS in predicting the outcomes of IVF.

A chronic cholestasis model was induced in mice by feeding a diet containing 3,5-diethoxycarbonyl-1,4-dihydro-2,4,6-trimethylpyridine(DDC). The effects of Ershiwuwei Songshi Pills(ESP) on endogenous metabolites in mice with chronic cholestasis were investigated by metabolomics analysis based on liquid chromatography-mass spectrometry(LC-MS). The results showed that ESP was effective in improving pathological injury and reducing serum levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST), alkaline phosphatase(ALP), and total bile acid in the model mice. Meanwhile, 13 common differential metabolites were revealed in metabolomic screening between the model/control group and the model/ESP group, including uric acid, glycolaldehyde, kynurenine, flavin adenine dinucleotide, L-3-phenyllactic acid, I-urobilin, leukotriene D4(LTD4), taurocholic acid, trioxilin A3, D-inositol-1,4-diphosphate, PC [16:0/20:2(11Z,14Z)], PC[14:0/22:2(13Z,16Z)], and PC[20:4(5Z,8Z,11Z,14Z)/20:4(5Z,8Z,11Z,14Z)]. After ESP intervention, the levels of all 13 differential metabolites were significantly retraced, and pathway analysis showed that ESP achieved its therapeutic effect mainly by affecting arachidonic acid metabolism, glycerophospholipid metabolism, tryptophan metabolism, and primary bile acid biosynthesis. This study elucidated the mechanism of action of ESP against chronic cholestasis based on metabolites.

Objective:To observe the regulatory effect of modified Shengmaiyin adjuvant chemotherapy on the nutritional status and immune function of children with acute lymphocyte （ALL）. Method:One hundred children with ALL chemotherapy were randomly divided into observation group and control group. Both groups were given VDLD regimen as the induction therapy and CAM regimen as the early therapy. Control group was given Shengmaiyin orally， 10 mL/time， 3 times/day. Observation group was given modified Shengmaiyin orally， 1 does/day. The course of treatment for both groups was 3 months. Micro-nutrition assessment （MNA） was carried out before and after treatment， and serum total protein （TB）， albumin （ALB）， prealbumin （PAB）， T cell CD4⁺， CD8⁺， immunoglobulin G （IgG）， IgM， IgA levels were detected before and after treatment. The ratio of CD4⁺/CD8⁺ was calculated. The traditional Chinese medicine （TCM） syndrome before and after treatment and the piper fatigue scale （PFS-R） and universal core scale of children's quality of life （PedsQL） were scored. The changes of white blood cells （WBC）， red blood cells （RBC）， hemoglobin （Hb） and platelets （PLT） were evaluated before and after treatment. Result:The nutritional status of the observation group was better than that of the control group after treatment （Z=2.018， P<0.05）. The observed fatigue was lighter than that of the control group （Z=2.029， P<0.05）. The MNA score of the observation group was higher than that of the control group （P<0.01）. The scores of PFS-R and deficiency of both Qi and blood were lower than those of the control group （P<0.01）. The CD4⁺ levels and CD4⁺/CD8⁺ levels of TB， ALB and PAB in the observation group were higher than those in the control group （P<0.01）， while the CD8⁺ was lower than the control group （P<0.01）. The IgM and IgA levels in the observation group were higher than those in the control group （P<0.01）. The RBC， Hb and PLT levels of the observation group were higher than those of the control group （P<0.01）. Conclusion:Modified Shengmaiyin can be used as adjuvant therapy for children with ALL chemotherapy by improving nutritional status， immune function and immune balance， reducing clinical symptoms， promoting the recovery of hematopoietic system and improving the quality of life.

Peritoneal ultrafiltration failure is a common reason for peritoneal dialysis (PD) withdrawal as well as mortality in PD patients. Based on the three-pore system, inter-cellular small pores and trans-cellular ultra-small pores (aquaporin-1) are mainly responsible for water transfer across the peritoneum. Both small and ultra-small pores-dependent water (free water) transport decline accompanied with time on PD, with more significant decrease in free water, resulting in peritoneal ultrafiltration failure. The reduction of free water transport is associated with fast peritoneal solute transfer, reduced crystalloid osmotic gradient due to increased interstitial glucose absorption, and declined osmotic conductance to glucose resulted from impaired aquaporin-1 function and peritoneal interstitial fibrosis. The decline of small pore-based water is mainly because of fast loss of crystalloid osmotic gradient, decrease of hydrostatic pressure mediated by peritoneal vasculopathy, as well as reduced absolute number of small pores. The current review discusses the advance on pathogenesis of acquired peritoneal ultrafiltration failure in long-term PD.

OBJECTIVE: To select potential molecules that can target viral spike proteins, which may potentially interrupt the interaction between the human angiotension-converting enzyme 2 (ACE2) receptor and viral spike protein by virtual screening. METHODS: The three-dimensional (3D)-coordinate file of the receptor-binding domain (RBD)-ACE2 complex for searching a suitable docking pocket was firstly downloaded and prepared. Secondly, approximately 15,000 molecular candidates were prepared, including US Food and Drug Administration (FDA)-approved drugs from DrugBank and natural compounds from Traditional Chinese Medicine Systems Pharmacology (TCMSP), for the docking process. Then, virtual screening was performed and the binding energy in Autodock Vina was calculated. Finally, the top 20 molecules with high binding energy and their Chinese medicine (CM) herb sources were listed in this paper. RESULTS: It was found that digitoxin, a cardiac glycoside in DrugBank and bisindigotin in TCMSP had the highest docking scores. Interestingly, two of the CM herbs containing the natural compounds that had relatively high binding scores, Forsythiae fructus and Isatidis radix, are components of Lianhua Qingwen (), a CM formula reportedly exerting activity against severe acute respiratory syndrome (SARS)-Cov-2. Moreover, raltegravir, an HIV integrase inhibitor, was found to have a relatively high binding score. CONCLUSIONS A class of compounds, which are from FDA-approved drugs and CM natural compounds, that had high binding energy with RBD of the viral spike protein. Our work provides potential candidates for other researchers to identify inhibitors to prevent SARS-CoV-2 infection, and highlights the importance of CM and integrative application of CM and Western medicine on treating COVID-19.
