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.

Objective To investigate the effectiveness and safety of intranasal different dose of dexmedetomidine for pediatric echocardiography sedation and to discuss the factors concerning recovery.Methods In a single-blinded randomized clinical trial,183 children were studied with a range of 2months and 33 months of age,and American Society of Anesthesiologists(ASA) physical status Ⅰ to Ⅱ.Those children were divided randomly into one of three groups.Groups D1,D2,and D3,which were received intranasal dexmedetomidine 1.0,1.5,and 2.0 μg/kg,respectively.The induction time,recovery time,examination time,and total sedation time were compared.The success rate of sedation and the occurrence of any side-effects with the drug were compared.Sex,age,weight,dose,induction time,and examination time were used as independent valuations,the recovery time was used as dependent valuation,and then the multiple linear regression analysis was performed to filtrate and formulate the valuable factors influencing recovery time.Results The induction time had no significantly difference among groups (P ＞ 0.05).The recovery time of group D3 was longer than group D1 and group D2 (P ＜ 0.05).The total sedation time of group D3 was longer than group D1 (P ＜ 0.05).The success rate of sedation and the incidence of sideeffects had no significantly difference among groups (P ＞0.05).Children's weight and medicine dose were found to affect recovery time.Conclusions Intranasal dexmedetomidine 1 ～ 2 μg/kg could be used effectively and safely in children undergoing echocardiography examination.Weight and dose were considered as key indexes to predict recovery time.

Background and purpose:It was reported that chemokine receptor CXCR4 and its ligand stromal cell-derived factor 1(SDF-1)were involved in the proliferation,differentiation,and metastasis of tumor.This study was designed to observe the expression of chemokine receptor CXCR4 in hypopharyngeal squamous cell carcinoma tissue and study the relationship between the expression of chemokine receptor CXCR4 and different clinicopathlogical characteristics,and further to explore the clinical significance.Methods:For the detection of the expression of chemokine receptor CXCR4,43 primary hypopharyngeal squamous cell carcinoma tissues,27 normal hypopharyngeal tissues,34 lymph node metastastatic lesions and 9 normal lymph node lesions were detected by immunohistochemical method using rabbit anti-human CXCR4 polyclonal antibody.Results:The positive expression rates of CXCR4 in 43 hypopharyngeal carcinoma tissues and normal tissues were 95.3% and 22.2%,respectively(P

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 summarize the magnetic resonance imaging/ 1 H-magnetic resonance spectroscopy (MRI/1 H-MRS) features of tumor-like inflammatory demyelinating diseases (TIDD),and investigate the clinical value of MRI/1 H-MRS.Methods MRI features of 10 cases of TIDD in brain confirmed by pathology were retrospectively analyzed and compared with pathology.Results The lesions mainly located in the white matter with mild mass effect.MRI scan all showed low T1 high T2 signal,and 7 cases showed high signal,3 cases showed slightly high or mixed signals on DWI.Enhanced MRI showed 5 cases with significant enhancement withopen loop sign,4 cases with significant patchy or nodular enhancement,1 case with mild flakes or linear enhancement.Three cases showed expanded blood vessels and plumbed to the lateral wall inside the edge of the lesions.1H-MRS performance showed 4 cases all with significantly increased Lac and Lip; 3 cases with rised glutamate and glutamine complex β,γ-Glx peaks,reduced N-acetylaspartate acid (NAA),increased Cho to varying degrees.All pathological changes were demyelination,perivascular inflammatory infiltration and reactive gliosis,hypertrophy and abnormal mitotic figure.Seven cases could be seen obesity glial cells.Conclusions TIDD had its salient MRI features:lesion had obvious edema and mild mass effect,MRI enhancement showed open loop sign and small veins expansed,on perfusion-weighted imaging it showed low perfusion.1H-MRS showed β,γ-Glx peaks,Lac and Lip peaks significantly increased,NAA slightly reduced,Cho mildly elevated.Comprehensively analyzing the MRI and 1H-MRS features,combined with clinical manifestations,contribute to the diagnosis of the disease.

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.
