METHODS: Between June 2012 and November 2015, 18 cases (18 fingers) of fresh extra-articular fracture of the proximal phalangeal base were treated, including 16 males and 2 females with an average age of 31 years (range, 21-57 years). The causes included strike injury in 10 cases, fall injury in 4 cases, mechanical injury in 1 case, twist injury in 1 case, crush injury in 1 case, and cutting injury in 1 case. The injured fingers were little finger in 16 cases, ring finger in 1 case, and index finger in 1 case. Of the 18 cases, 17 had closed fractures and 1 had open fracture. X-ray film showed transverse fracture in 14 cases and transverse-oblique fracture in 4 cases. The time between injury and operation was 3 hours to 4 days (mean, 2 days). After anatomical reduction, two Kirschner wires were used for intramedullary fixation. Functional exercises were done at 2 days after operation. The Kirschner wires were removed at 4 weeks after operation.

Objective To investigate Monilia infection and adverse pregnancy outcomes of pregnant women in labor.Methods Before informed consent,542 cases of pregnant women in labor were collected in Obstetrics Department of Maternity and Child Healthcare of Maoming City from January 2013 to April 2014,and all of these cases were examined by Monilia inspec-tion of vaginal secretions.All of these cases were 20 to 30 years old,without vaginal pathogenic infection symptoms,but in-cluded in a few of formulation of clinical features of vaginal Candida infection.With the two methods of 10% potassium hy-droxide solution wet sheet and Gram staining,if blastospore or pseudohypha of Candida mycoderma were found out in the two methods under microscope,this case was diagnosed as positive result,otherwise as negative result.Respectively choosing positive cases as observation group,and negative cases as control group,the indexes of premature rupture of membranes,per-ineum wound infection,neonatal thrush and neonatal diaper rash of the two groups were recorded.The statistical method:e-numeration data by chi-square test,measurement data using analysis of varianc.Results The positive rate of Monilia was 23.1% (125/542),higher than 19.3% reported in domestic.The incidence rates of neonatal diaper rash,premature rupture of membranes,neonatal thrush and perineum wound infection of the observation group were respectively 19.2%,8.0%, 16.8% and 12.8%,all much higher than the control group respectively was 8.4%,1.2%,3.8% and 1.7%,(χ2 =12.578~29.273,all P <0.01).Conclusion Monilia infection of pregnant women in labor could increase the chance of adverse preg-nancy outcomes.Healthy or clinical doctors should suggest that pregnant women early carry out routine examination and ear-ly treatment,in order to prevent adverse pregnancy outcomes.

OBJECTIVETo explore the molecular pathological diagnosis of mucosa-associated lymphoid tissue lymphoma(MALTL).

METHODSSixty MALTL paraffin embedding specimens were analyzed retrospectively. The distribution of the primary lesion, morphology, immunophenotype, IgH gene cloning rearrangement were evaluated.

RESULTSThe main risk area for the patients with MALTL was gastric area(37%), in the second place was salivary gland(20%), in the third place was intestine (12%), orbit and ocular adnexa(12%); at low magnification, MALTL specimens manifasted diffuse growth majority, a few of nodular structure, lymphoma cell forms were diversified; The results of immunohistochemical detection showed that the CD20 and the BCL-2 were positive, the CD3, CD5, CD10, CD23, cyclin D1 and CD21 were negative, 17 specimen kappa or lambda express more obviously, their sensibility was 28.33%(17/60); 61.67%(37/60) developed IgH gene rearrangement, 19 specimen IgH gene rearrangement monoclonal and kappa or lambda were negative, the positive rate of both combined detections was 68.33%.

CONCLUSIONThe tissue morphologic characteristics and immuno-histochemistry detection are the basic means for MALTL diagnosis, the detection of IgH gene reasragement and Kappa or lamda restrictive expression has the practical importance for MALTL diagnosis, both combination can show higher positive rate for MALTL diagnosis.

OBJECTIVETo investigating genetic effects of workers occupationally exposed to mercury (Hg).

METHODSThe peripheral lymphocytes from 20 workers exposed to mercury and 20 controls were measured with micronucleus test, comet assay, hrpt gene mutation test and TCR gene mutation test.

RESULTSThe mean micronuclei rate(MNR) and mean micronucleated cells rate(MCR) in 20 workers were (5.90 +/- 0.91) per thousand and (5.30 +/- 0.81) per thousand, respectively while MNR and MCR in controls were (1.50 +/- 0.47) per thousand and (1.30 +/- 0.31) per thousand respectively, The difference of MNR and MCR between workers and controls was very significant (P < 0.01). The mean tail length (MTL) of workers and controls were (3.16 +/- 0.31) and (0.99 +/- 0.07) microm, respectively. The mean tail moment (MTM) of workers and controls were 1.63 +/- 0.22 and 0.39 +/- 0.03, respectively, There was a significant difference in MTL and MTM between workers and controls(P < 0.01). When the average mutation frequencies (Mfs-hprt) of hprt and (Mfs-TCR) of TCR of workers were compared with those of controls, there were not significant difference (P > 0.05).

CONCLUSIONThe results of the investigation indicated that the adverse genetic effects in workers occupationally exposed to mercury could be detected.

Bladder cancer is the most common malignant tumor in the urinary system.Currently,the clinical treatment options for bladder cancer mainly include surgery,chemotherapy,radiotherapy,immunotherapy,targeted therapy,photodynamic therapy,combination therapy,etc.The conventional treatment and administration strategies for bladder cancer primarily depend on the tumor stage and the extent of metastasis.However,in the process of non-surgical treatment,drugs lack specificity and targeting.Once the dosage is improperly controlled,drugs will damage normal cells when attacking cancer cells,which will lead to poor efficacy and multiple side effects.Nanomedicine is an emerging interdisciplinary field that utilizes nanomaterials and technologies in nanomedicine to provide disruptive technologies for traditional treatments,with advantages such as targeted delivery and high efficiency with low toxicity.Many nanotechnologies have become hot topics in clinical research in the field of medicine.Functionalized nanoparticles can actively or passively target specific cells within target organs,such as bladder cancer cells,by altering their surface properties,thereby enhancing drug delivery precision,reducing damage to normal cells,and improving treatment efficacy.This article provides an overview of the progress in classical and novel treatment approaches to bladder cancer,with a particular focus on the potential applications and future development directions of nanotechnology in the treatment of bladder cancer,providing important reference for personalized therapy and clinical translation in bladder cancer.
