AIM: To compare the clinical efficacy and safety of phacoemulsification and small incision non -phacoemulsification cataract surgery, and provide better options for clinical cataract treatment.
METHODS: According to the different operation methods, 98 cases of simple senile cataract patients in our hospital were divided into control group and treatment group, 49 cases in each. The control group received ultrasonic emulsification operation treatment; treatment group were treated by small incision non -phacoemulsification. Visual acuity, astigmatism values, average operation time, and complications were compared between two groups before and after operation.
RESULTS: There was no significant difference in preoperative corneal astigmatism values of two groups at 3mo between two groups (P>0. 05). On other times, vision and corneal astigmatism were obviously better than those before operation (P<0. 05). The average vision, corneal astigmatism values and complications incidence of two group at operation time and different postoperative time had no statistical difference (P>0. 05). When the lens nucleus hardness was at Ⅰ~Ⅲ level, corneal endothelial cell count of two groups had no significant difference ( P>0.05). When the lens nucleus hardness was at Ⅳ ~ Ⅴlevel, there was statistical difference (P<0. 05).
CONCLUSION: Small incision non-phacoemulsification cataract surgery has the similarly efficacy compared with phacoemulsification. It should be based on the actual situation of the hardness of nuclear to select the appropriate surgical treatment.

OBJECTIVETo report a case of simple congenital bilateral ejaculatory duct absence (EDA) complicated with seminal vesicle cyst and review the relevant literature in order to improve the diagnosis and treatment of the disease.

METHODSWe retrospectively reviewed the clinical data of a case of bilateral congenital EDA complicated with seminal vesicle cyst, reviewed the relevant literature at home and abroad, and comprehensively analyzed the embryonic development, diagnosis, and treatment of congenital EDA.

RESULTSThe patient was a 23-year-old man, present at the clinic for infertility after married for a year. Vasography and other imaging examinations confirmed simple congenital bilateral EDA complicated with seminal vesicle cyst. Pathologic biopsy showed normal spermatogenic function of the testes.

CONCLUSIONCongenital EDA originates from embryonic developmental defect of the mesonephric duct, and it can be confirmed by vasography. Transurethral incision of the ejaculatory duct and intracytoplasmic sperm injection can be employed for the treatment of bilateral EDA.

In ischemic hypertrophic myocardium, contractile dysfunction can be attributed to the decreased calcium induced calcium release (CICR) in cytoplasm. This study aimed to investigate the electrophysiological properties and the expression of L calcium channel subunits in post-MI myocardium. The ischemic heart remodeling model was established in SD rats. The expressions of calcium channel subunits were determined by realtime RT-PCR. Whole cell patch clamp was used to record the electrophysiological properties of L calcium channel. The results showed that the L calcium channel agonist Bayk 8644 induced the significantly decreased CICR in the rat cardiomyocyte 6 weeks after myocardial infarction (MI). In the post-MI cardiomyocytes, the amplitude of I(CaL) decreased dramatically and the inactivation curve of the current shifted to more negative potential. At mRNA level, the expression of the calcium channel alpha1c, beta2c subunits decreased dramatically in the ventricle of post-MI rats. The expression of alpha2/delta subunit, however, remained constant. It is concluded that the abnormal expression of the L calcium channel subunits in post-MI cardiomyocytes contributes to the ICaL decrease at early stage of the ischemic remodeling in cardiomyocytes, which leads to the decreased CICR in the cell and contractile dysfunction of myocardium.
