Objectives: To evaluate the efficacy of phacoemulsification and foldable IOL implantation with limbal tunnel incision. Methods: A 3.2mm limbal tunnel incision was made on 72 eyes of 66 patients with senile, complicated and traumatic cataract. Phacoemulsification and foldable IOL implantation was performed. Visual acuity, corneal curvature and corneal topography were measured after the surgery. Results: One day, one week and one month after the surgery, visual acuity exceeded 0.5 in 69.4%, 80.6%,86.1% of the patients respectively. One week after the surgery, the mean astigmatism was (1.85±0.89)D(P<0.01), 0.30 D more than that before the surgery. Corneal topography showed that the incision was steep or flat. One month after the surgery, the mean astigmatism was (1.48±1.02)D,P>0.05,corneal topography had recovered. Conclusions: Phacoemulsification and foldable IOL implantation with limbal tunnel incision have comparatively simple, with less postoperative inflammation and faster recovery of visual acuity.

OBJECTIVE:To study improvement effect of modified mahuang chanyi decoction on allergic rhinitis(AR)model guinea pigs and its mechanism. METHODS:32 guinea pigs were randomly divided into normal group (0.9% Sodium chloride in-jection),model group (0.9% Sodium chloride injection),experimental [Modified mahuang chanyi decoction,5.18 g (medicinal materials)/kg] group and control [Fluticasone propionate nasal spray,50 μg/(guinea pig·d)] group. Except for normal group,other groups received ovalbumin 30 mg and calmogastrin 30 mg intraperitoneally to induce AR model. Except for control group,other groups were given relevant medicine intragastrically,twice a day for consecutive 15 d. Nasal symptoms of guinea pigs were ob-served and recorded,and then analyzed and scored. The protein expression of nasal mucosa SHP-1 was detected by immunohisto-chemistry,the serum contents of IL-4 and IFN-γ were determined by enzyme-linked immunosorbent assay. RESULTS:Compared with normal group,model group suffered from AR symptom,and nasal symptoms score was increased;and the protein expression of nasal mucosa SHP-1 and the serum content of IL-4 increased,while the content of IFN-γ decreased(P<0.05). Compared with model group,AR symptom of experimental group and control group were improved;nasal symptoms score,the protein expression of nasal mucosa SHP-1 and the serum content of IL-4 decreased while the content of IFN-γ increased(P<0.05). CONCLUSIONS:Modified mahuang chanyi decoction shows certain improvement effect on AR,and its mechanism is associated the decrease of IL-4 content and the increase of IFN-γcontent in serum.

OBJECTIVETo investigate the association of male reproductive tract infection (RTI) with semen parameters and sperm DNA damage.
METHODSWe classified 1 084 males attending the infertility clinic into an RTI group (n = 300) and a non-RTI control group (n = 784). According to the WHO standards, we obtained routine semen parameters, detected sperm morphology, and determined the sperm DNA fragmentation index (DFI) by sperm chromatin structure assay.
RESULTSThere were statistically significant differences between the RTI and control groups in the semen volume ( [2.58 ± 1.20] vs [3.00 ± 2.10] ml), grade a + b sperm ([50.6 ± 17.2] vs [53.2 ± 15.8]%), grade d sperm ( [39. 8 ± 17.8] vs [36.5 ± 16.2]%), and total sperm count ([218.5 ± 185.0 ] vs [278.5 ± 375.5 ] x 10(6)/ejaculate) (all P < 0.05), but not in the males' age, sperm concentration or pH value (P > 0.05). The percentage of morphologically normal sperm was significantly lower ([3.46 ± 2.90] vs [4.61 ± 3.60%, P < 0.05) but the DFI was markedly higher in the RTI group than in the control ([19.4 ± 11.4] vs [15.2 ± 8.8]% , P < 0.01). The percentage of the cases with DFI > 30% was remarkably higher (13.0 vs 5.74% ) while that of the cases with DFI < 10% dramatically lower in the former than in the latter (16.0 vs 28.0%). The level of seminal plasma elastase was correlated negatively to sperm concentration, sperm count, and the percentage of morphologically normal sperm (P < 0.05) but positively to DFI and grade d sperm (P < 0.05 or P < 0.01).
CONCLUSIONMale reproductive tract infection not only affects semen parameters and sperm morphology but also causes serious sperm DNA damage.

Objective To evaluate the efficacy of DSA-guided percutaneous transhepatic gallbladder catheter drainage (PTGCD) in treating aged patients with acute cholecystitis complicated by severe diseases. Methods The clinical data of 15 aged patients with acute cholecystitis or complicated by severe diseases, who were encountered at authors’ hospital in the past three years and were treated with PTGCD, were retrospectively analyzed. The clinical results were discussed. Results PTGCD was successfully accomplished with single procedure in all 15 patients. Abdominal pain was relieved within one to three days, and the abdominal symptoms and signs subsided or disappeared. Reexamination of routine blood test showed that the white blood cell count decreased to normal range in 1 - 2 weeks, and complete cure was achieved in some patients. Secondary surgery was carried out in some patients after the clinical condition was improved. During the follow-up period no complications occurred in all patients except one who developed biliary leakage after the catheter was retrieved two weeks after the treatment. Conclusion For the treatment of complicated acute cholecystitis in aged patients who are not suitable to receive surgery, DSA-guided percutaneous transhepatic gallbladder catheter drainage is an ideal therapeutic means as it can significantly relieve clinical symptoms.

Objective To develop and validate a simple and reliable HPLC method for the analysis of L-carnitine in human seminal plasma and to investigate its clinical significance as a potentially useful index of infertile.Methods After proteins in seminal plasma are precipitated with acetonitrile,L-carnitine in seminal plasma was derivatized to form its ester.HPLC separation of the sample solution was performed on a Lichrospher SiO_2 column and detected by ultraviolet absorbance at 260 nm.A mobile phase composed of acetonitrile-citrie acid buffer(containing 12 mmol/L triethanolamine,pH 5.0)was found to be the most suitable for this separation at a flow rate of 1.2 ml/min and enabled the baseline separation of the L-carnitine from interferences with isocratic elution.The L-carnitine levels in seminal plasma were studied in both 87 patients with infertility and 30 control subjects.Results Under the chromatographic conditions described, the L-carnitine derivative had a retention time of approximately 13 min.Good separation and detectability of L-carnitine in human seminal plasma sample were obtained.The method proved to be linear in the range of L-carnitine from 0 ?mol/L to 1000 ?mol/L.The relative standard deviations of within-and between-assay for L-carnitine analysis were 1.23% and 1.36%,respectively.The recoveries were 91.6% -96.5% for the human seminal plasma samples.L-carnitine concentrations in the populations were(392.7?107.2)?mol/L in the fertile group(n=30),(270.0?83.9)?mol/L in asthenozoospermia group(n=29),(187.9? 43.9)?mol/L in oligozoospermia group(n=19)and(175.7?67.1)?mol/L in oligoasthenozoospermia group(n=39).The large difference(P0.05).Conclusion The determination of L-carnitine level in seminal plasma may prove useful as a potentially biochemical marker of fertility and this is a useful guidance for the clinic therapy and the mechanismic study on the male reproduction.
