ABSTRACT
·AIM: To Evaluate the effects of different capsulotomy diameters during phacoemulsification on corneal and blood aqueous barrier. ·METHODS: Totally 78 cases (100 eyes) with cataract were treated by femtosecond laser assisted phacoemulsification. The patients were randomly divided into two groups. There were 36 cases (50 eyes) in experimental group, in which the capsulotomy diameter was 4.7mm,and 42 cases(50 eyes) in the control group, in which the capsulotomy diameter was 6. 0mm. Phacoemulsification power and time were recorded for each procedure. Follow-up exams were performed on 1d, 1wk and 2mo after surgery. Preoperative and postoperative best corrected visual acuity, central corneal thickness, aqueous flare, corneal endothelial cell count were assessed for the two groups. · RESULTS: No significant difference was found on preoperative best corrected visual acuity ( BCVA), hardness of the lens nucleus, centrel corneal thickness (CCT) and the effective phaco time and the average phaco power of the two groups(P>0.05). There was also no statistically significant difference on BCVA between the two groups after surgery(P>0.05). The change of central corneal thickness and the aqueous flare cells in the experimental group were less than those in the control group at 1d and 1wk postoperatively (P<0.05), while the difference was not obvious at 2mo after (P>0.05). The rate of lost corneal endothelial cell was significantly lower in the experimental group than the control group at 2mo postoperatively (P>0.05). · CONCLUSION: The phacoemulsification with small capsulotomy diameters decreases the injury to the corneal and blood aqueous barrier. The patients recovered more quickly.
ABSTRACT
AIM:To observe and analyze visual quality changes of the patients with posterior capsule opacification ( PCO ) Nd:YAG laser posterior capsular dissection, including the change of the best corrected vision acuity ( BCVA ) , total high- order aberration ( tHOA ) , and the modulation transfer function ( MTF) . METHODS:In this prospective observational study, 100 cases of patients ( 100 eyes ) with posterior cataract underwent Nd:YAG laser posterior capsular dissection ( posterior capsular diameter dissected was 5mm or higher). The mean age was 65. 52±7. 01 years old. The change of the BCVA was collected. The tHOA and MTF under the 3mm and 5mm pupil diameter were assessed by iTrace respectively before and after Nd:YAG laser posterior capsular dissection. RESULTS:All the surgery went well without obvious intraoperative and postoperative complications happened. The preoperative BCVA was 0. 451 ± 0. 023 while the postoperative BCVA was 0. 763±0. 025. The difference of BCVA before and after Nd: YAG laser surgery was statistically significant (PCONCLUSION: Patients with posterior capsule opacification ( PCO ) Nd:YAG laser posterior capsular dissection can help improve BCVA, reduce tHOA, increase MTF tHOA values, and significantly improve visual quality of patients.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of Dingguier umbilical paste on rats with functional dyspepsia and mice with splenic asthenia, and investigate the related mechanism.</p><p><b>METHOD</b>Functional dyspepsia models of rats were made by irregular food intake plus diluted hydrochloric acid. Successional treatments were offered for 14 days. The rats weights, contents of serum NO, AChE and MC were measured. The rats with splenic asthenia were made by rhubarb feed, and observed the affection of gastric emptying.</p><p><b>RESULT</b>Compared with those in the model control group, the weight of rats in all dosages Dingguier umbilical paste groups increased obviously (P < 0.05), pepsin activity of rats in the dosage (1.34 g x kg(-1)) Dingguier umbilical paste groups was significantly higher and the contents of NO and quantities of MC in the dosage (2.67 g x kg(-1)) Dingguier umbilical paste groups decreased clearly (P < 0.05), and the contents of serum AChE in all dosages Dingguier umbilical paste groups rose apparently. The weight of mice with splenic asthenia increased obviously, accelerated gastric emptying, and improved the symptom.</p><p><b>CONCLUSION</b>Dingguier umbilical paste has significant improvement of indigestion. The related mechanism may be to reduce the content of serum NO and the quantity of MC and enhance the content of serum AChE.</p>

<p><b>OBJECTIVE</b>To observe the influence of therapy with Chinese medicine Lirukang Granule (, LRKG) combined with psychological intervention on anxiety states and sex hormones in patients with cyclomastopathy and menoxenia.</p><p><b>METHODS</b>A total of 470 subjects were randomly assigned to three groups by the net-central randomization system, the treatment group (161 patients, treated with LRKG and psychological intervention), the Chinese medicine group (157 patients, treated with LRKG), and the psychological intervention group (152 patients, treated with psychological intervention). The dose of LRKG was 12 g three times per day; psychological intervention included establishing relations, cognitive intervention and psychological persuasion, 30-40 min per session, once a week. The therapy duration for all groups was three months. The efficacy was compared and anxiety state/State-Trait Anxiety Invertory (STAI) scoring was measured before and after treatment. The serum estradiol (E2), progesterone (P), prolactin (PRL) and follicle stimulating hormone (FSH) levels of 60 patients selected randomly from each group during the luteal phase were measured before and after treatment, and a group of 20 healthy women were evaluated for comparison. A follow-up was arranged for one year after treatment.</p><p><b>RESULTS</b>Thirty subjects were lost to follow-up. (1) Comparison of efficacy: the markedly effective rate and the total effective rate of the treatment group were 86.67% (131/150) and 98.00% (147/150), respectively; of the Chinese medicine group, 64.58% (93/144) and 90.27% (130/144), respectively; and of the psychological intervention group, 0% (0/146) and 3.42% (5/146), respectively. The markedly effective rate and the total effective rate in the treatment group were significantly higher than those in the Chinese medicine and psychological intervention groups (P < 0.05). (2) Comparison of STAI scoring: STAI scoring was decreased dramatically in the treatment group after treatment compared with that of the Chinese medicine group (P < 0.01), but there was no significant difference compared with the psychological intervention group. (3) Comparison of levels of sex hormones: E2, P, PRL and FSH of the three patient groups were disordered before treatment, and significantly different from healthy women (P < 0.01). After treatment, the levels of P and FSH of the treatment group were significantly increased (P < 0.01), E2 and PRL were significantly reduced, which were also significantly decreased compared with the psychological intervention groups (P < 0.01). (4) FOLLOW-UP: the markedly effective rate and the total effective rate of the treatment group remained higher than those of the other two groups after one year of treatment (P < 0.05). (5) Adverse reactions: no obvious adverse reactions were found among the three groups.</p><p><b>CONCLUSIONS</b>Therapy with Chinese medicine combined with psychological intervention was effective for short-term and long-term treatment of cyclomastopathy and menoxenia. The mechanism might be related to the regulation of sex hormones.</p>
