Objective To investigate the clinical efficacy of nifedipine sustained-release formulation(SR)and nifedipine controlled-release(GITS)in the treatment of essential hypertension.Methods 160 patients with essential hypertension were randomly divided into two groups.The SR group was treated with SR 20 mg twice a day;GITS group was treated with GITS 30 mg once a day.All patients were given ambulatory blood pressure monitoring(ABPM)and observed the 24-hour average blood pressure,heart rate,changes in the trough/peak(T/P)values,and adverse reactions before and after treatment in two groups.Results The T/P value of systolic blood pressure(SBP)and diastolic(DBP)in the GITS group was 68.5％,74.6％,respectively,which were higher than those of SR group(57.2％,61.1％)(x2=6.32,7.05,all P＜0.05);GITS group was significantly lower than the SR group in heart rate(t=4.17,P＜0.05);Adverse reactions between two groups had no significant difference(x2=0.16,P＞0.05).Conclusion SR and GITS can effectively lower blood pressure,but GITS is more efficient,stable,safe,small impact on the heart rate.

Objective To inquire into the value of Liechtenstein Hernioplasty in the therapy of oblique or direct hernia.Method Liechtenstein was used in the therapy of 163 cases of oblique hernia (154 cases) and direct hernia (9 cases) from Feb.1998 to Jun.2001 and the clinical data was retrospectively studied.Most of them are of onset hernia except 8 cases of recurrent hernia.In 148 cases,the diameter of hernia ring is less than 2.5 cm and 30.1% of patients are elder than 65.The emergent operation was adopted in 12 cases.Results Off-bed exercises can be admitted at early stage of postoperation with slight pain and no local tension.Total recovery was obtained in 5-10 days after operation.After 6-36 months' follow-up,no mortality and less recurrence was detected.Conclusions There are so many advantages to treat oblique or direct hernia with Liechtenstein, such as minimized trauma, accelerated recovery,low recurrence rate and low cost. The indication of this operation involved all kinds of hernia (onset or recurrence of oblique or direct hernia,emergent operation of incarcerated oblique hernia, etc).

Objective To discuss the CT features and the prognosis of hypoxic ischemic encephalopathy (HIE) with intracranial hemorrhages in neonates.Methods The CT features of the HIE with intracranial hemorrhage were analyzed and follow-up studied in 64 cases.Results Of all the 64 cases with HIE, 53 cases were associated with subarachnoid hemorrhage (SAH), and all cases were normal in the follow-up study after 1 month. 1 case was associated with intraventricle hemorrhage (IVH), 10 cases were associated with mixed bleeding (SAH+IVH in 3 cases, IVH+IPH in 1 case, SAH+IPH in 2 cases, SAH+SHE in 2 cases, SAH+SDH in 2 cases). Of the follow-up studies on 10 mixed bleeding cases, 1 was normal, 1 was dead, and the others were cerebromalacia, cerebral atrophy, porencephaly and calcium.Conclusion Different intracranial hemorrhages results in different prognosis.

In recent years, a growing number of studies have shown that non-coding RNA plays an important role in the pathogenesis and development of epilepsy, and is involved in neuroinflammation, cell apoptosis, synaptic remodeling and cell differentiation in epilepsy. This review focused on the recent research progress in the relationship between microRNA, long-nocoding RNA and circular RNA with epilepsy.

Objective To observe the morphological changes of corneal nerve in experimental herpes simplex keratitis (HSK) in rabbit eyes. Methods Inoculation of the scarified cornea with herpes simplex virus-Ⅰ(HSV-Ⅰ)leads to herpetic infection of cornea. The HSK was detected by slit lamp and polymerase chain reaction(PCR), and the changes of corneal nerves in various periods with methylene blue vital staining and ultrastructure of corneal nerve were studied. Results Under light microscope, fewer corneal nerve bundles were observed, scattered with lower density of nerve fiber at center of cornea on the 4th day after the infection. At days 7 and 14, the seriously damaged nerve fiber was intermittent. The neuraxon became shorter with little polarity and the density of nerve fiber was extremely low. At day 30, the density was still low while the nerve fiber was approximately normal. Under electromicroscope, at day 4, the lamellar sheath of nerve fiber in the epitheliums appeared intermittent, and the neuroplasm of endings was partly lysed. During day 7 to day 14,neuroplasm was damaged and became vacuolar. The mitochondria swelled with vacuolar crest, and then were destroyed and lysed. The nerves in stroma were also injured. On day 30, neurilemma sheath was still intermittent with the decrease of microfilament and racuole. Conclusion HSK leads to the damage of nerve and the decrease of nerval density, and the damage of corneal nerve repairs very slowly.

[Summary] To investigate the association of rs2282679 A/C polymorphism in vitamin D binding protein gene with vitamin D deficiency in 1 216 participants.A standardized questionnaire was applied to collect information on alcohol consumption,smoking habits,and use of medications.Serum 25-hydroxyvitamin D [25 (OH) D] was determined by radioimmunoassay.Vitamin D binding protein genotypes were determined by SNaPshot method.1216participants included 457 women(37.6％),478 (39.3％)with vitamin D deficiency [25 (OH) D＜50 nmol/L],and 386 (31.7％) overweight/obese participants.The frequencies of rs2282679 CC,AC,and AA genotypes were 8.7％,41.0％,and 50.3％,respectively.The distributions of genotypes and alleles differed significantly between participants with sufficient vitamin D and those with vitamin D deficiency (P ＜ 0.05).There were significant differences in the serum levels of 25 (OH) D between three genotypes before and after being adjusted for covariates (P＜0.01).AA had a 22％ (OR =0.78,95％ CI 0.65-0.93,P =0.006) lowered risk of vitamin D deficiency compared with the whole studied population.Compared with CC genotype,AA had a 36％ lowered risk of vitamin D deficiency(OR =0.64,95 ％ CI 0.42-0.98,P =0.006),while there was no significant difference between AC and CC genotypes(OR=0.87,95％ CI0.57-1.34,P=0.53).In conclusion,the vitamin D binding protein rs2282679A/C polymorphism was significantly associated with serum level of 25 (OH) D and risk of vitamin D deficiency.
