Objective:To analyze the clinical characteristics of interstitial pulmonary fibrosis (IPF) in patients with Rheumatoid arthritis (RA). Methods: We retrospectively analyzed 198 RA patients with or without IPF. Characteristics of RA-IPF in clinical and lab data were analyzed. Age, duration of disease,clinical and laboratory parameters, history of smoking and medicine were compared between the patients with and without IPF. Results: (1) Among the 198 RA patients, 15.2% (30/198) were found with IPF. 100% RA-IPF patients had HRCT findings. However, 63.3% (19/30) had positive findings in chest X-ray, and only 46. 7% ( 14/30) had the complaints of cough and short breath. Velcro rales were found in 50.0% (15/30) patients with IPF and no acropachy occurred. Only one patient suffered from hypoxemia. IPF presented after the joint symptoms in most patients. (2 ) RA-IPF patients were older than those without IPF [(65.50±9.71) vs (55.22±12.98) years, P＜0.01]; Higher positivity of anti-keratin antibodies ( AKA) were found in RA-IPF compared to patients without IPF (61. 5% vs 35.9% , P =0.014). Furthermore, the levels of anti-cyclic citrullinated peptide (CCP) antibody were significantly higher in RA-IPF [(4.38±2.08) vs (3.20±2. 12) , P =0.01]. No differentiation of duration of disease, history of smoking and medicine, IgM rheumatoid factor, IgG rheumatoid factor, anti-nuclear antibody, anti-SSA antibody and levels of immunoglobins and complements were found between the two groups of RA patients with and without IPF. Conclusion: The clinical symptoms of IPF in RA patients are mild and more common in older patients. AKA and anti-CCP antibody might be important antibodies associated with RA-IPF.

AIM: To evaluate the efficacy of vitrectomy and pan-retinal photocoagulation followed with Ahmed implantation in management of neovascular glaucoma ( NVG) retrospectively.
METHODS: Vitrectomy combined with pan retinal photocoagulation and Ahmed implantation was performed on 15 cases ( 15 eyes ) with NVG. All patients were followed up for 12 ~ 36mo. The change of intraocular pressure (IOP), visual acuity, neovascularization of iris, complications were observed.
RESULTS: The visual acuity of 10 eyes was improved postoperative. IOP of postoperative 1, 6 and 12mo were decreased significantly compared with preoperative ( P<0.01 ) . Neovascularization of iris was reduced dramatically. No serious complications occurred.
CONCLUSION: Vitrectomy combined with pan retinal photocoagulation followed Ahmed implantation can manage NVG effectively.

AIM: To explore the effect of lacrimal duct laser with lacrimal drainage tubes and stents implantation for complexity dacryagogatresia.
METHODS: There were 65 patients ( 82 eyes ) with compound tears nasolacrimal duct obstruction who received lacrimal drainage tubes and stents implantation after laser. The lacrimal duct stents were removed through nasal cavity after 1mo. Lacrimal drainage tubes were removed after 3-6mo. Follow-up periods were 6mo to 1a.
RESULTS: In the 65 patients (82 eyes), 71 eyes were cured, 5 eyes improved, the efficient rate was 93%; there were 6 eyes (7%) with epiphora.
CONCLUSION: Lacrimal duct laser with lacrimal drainage tubes and stents implantation was efficient for complexity dacryagogatresia.

Background Bulbar conjunctiva tissue appears to be thinning,elasticity declined,tension reduced and fascia atrophied in conjunctivochalasis.Histopathological examination of conjunctivochalasis shows decrease of elastic fibers and melt of collagen fibers.But there are fewer studies on the ultrastructure of conjunctiva of conjunctivochalasis up to now.Objective This study was to investigate the ultrastructure change of conjunctiva tissue in conjunctivochalasis.Methods Five loose conjunctiva samples of conjunctivochalasis and 5 normal conjunctival tissue samples were collected and ultra-microstructure changes of these samples were observed under the transmission electron microscope.Results The number of fibroblasts in conjunctivochalasis lamina was progressively decreased.The shape of fibroblasts was long and fusiform.Somatic synapse was slim.Nucleus-cytoplasm ratio was increased.Disorder,scattered and broken of the collagen fibril were seen,and some areas were dissolved or lacunae.Normal conjunctival fibroblasts were oval or polygonal,with wieners and long somatic synapse,and intercellular matrix was full of collagen fibril and dense arranged fibers.Fibroblasts in fascia of eonjunctivochalasis were linear,and collagen fibril was seriously defected.Fascia fibroblasts of normal bulbar conjunctiva were spindleshaped and bigger than conjunctivochalasis fibroblasts.There were full of collagen fibrils in intercellular matrix.Conclusions The collagen fibril is decreased and fibroblast cells are degenerated in lamina and fascia of conjunctivochalasis.

OBJECTIVETo observe the effect of Fengshi No. 1 (FS1) in treating patients with active stage of rheumatoid arthritis (RA).

METHODSPatients with RA were randomly divided into two groups, the 40 patients in the treated group were treated with combined therapy of methotrexate (MTX), sulfasalazine (SSZ) and FS1, and the 20 in the control groups were treated with MTX and SSZ alone.

RESULTSIn the treated group, the total effective rate was 97.5%, the clinical controlled and markedly effective rate 95.0% and the occurrence rate of side-toxic reaction 10.0%, as compared with those in the control group, 60.0%, 20.0% and 45.0% respectively, the difference was significant (chi 2 = 11.91, 32.23 and 7.67 respectively, all P < 0.01). The effect in the treated group was superior to that in the control group in abating joint swelling and pain, improving function of joint, reducing immune indices and ameliorating iconographic features (P < 0.01 or P < 0.05).

CONCLUSIONFS1 not only has the effects of anti-inflammation, analgesis, regulating immune reaction, but also could retard the occurring of bone destruction, reduce the toxic-side effects of MTX and SSZ.

Objective To investigate the therapeutic effect of large dose mucosolvan combined variant flow rate continuous positive airway by nasal mask on neonatal respiratory distress syndrome(NRDS).Methods One hundred and fourteen newborns with NRDS were randomly divided into treatment group(58 cases) and control group(56 cases),on the base of same combined therapy,the cases in control group only underwent oxygen-absorbing by head set with the flow rate 4-6 L/min,and the cases in treatment group were given large dose mucosolvan(Ambroxol Hydrochloride) 30 mg/(kg?d) + 5%GS 20 mL,for two times and variant flow rate continuous positive airway by nasal mask(NCPAP),the parameter setting flow rate 6-8 L/min,FiO_2 0.4-0.6,pressure 5-8 cm H_2O.The clinical symptom and blood gas analysis after 12 and 48 hours were observed and compared the changes of pa(O_2),pa(CO_2),pa(O_2)/FiO_2 in two groups.Results The dyspnea and groan in 44 cases in the treatment group lessoned or vanished,pa(O_2) rised and pa(CO_2) lowered,the oxygenation index obviously increased,the cases with RDS grade Ⅰand gradeⅡ had better therapeutic effect,and the cases with RDS grade Ⅲ(X-ray)and Ⅳ had not manifest effect,the total effective rate was 75.8% in treatment group and 26.7% in control group.There were significant difference in therapeutic effect and oxygenation index between two groups.Conclusions Large dose mucosolvan(combi)-ning variant flow rate continuous positive airway by nasal mask can significantly improve the ventilation and oxygenation function and there are significant therapeutic effect in NRDS,especially in the NRDS grade Ⅰand gradeⅡ,the trachea cannula may be avoided and mechanical ventilation rate may be decreased if the therapeutic method can be used in earlier period.

Objective To discuss the clinical value of 99Tcm-sestamibi(99Tcm-MIBI) myocardial perfusion imaging on detecting myocardial ischemia in children with Kawasaki disease(KD) at convalescence period.Methods Twenty-one children wih KD at convalescence period were divided into 2 groups according to results of echocardiography.Four cases with coronary artery dilation,17 cases without coronary artery dilation.All cases accepted dipyridamole stress myocardial perfusion imaging.These patients who had positive results were given rest myocardial perfusion imaging again next day.Results Among 21 cases,9 cases(42.8%) were positive in perfusion imaging.Four cases with coronary artery dilation showed myocardial ischemia in different degree detected by myocardial perfusion imaging.Among 17 cases without coronary artery dilation,5 cases(29.4%) were positive.Conclusions Compared to echocardiography,99Tcm-MIBI myocardial perfusion imaging can objectively evaluate the location,extent and degree of myocardial ischemia of children with KD.It will be a routine test in observing its phase development.

Objective To evaluate tear ferning changes of conjunctivochalasis.Design Prospective case study series.Partici- pants 30 patients(60 eyes)of conjunctivochalasis and normal subjects were selected.Methods The subjects were observed with gen- eral ophthalmic examination and tear fern test(TFT).Tear ferning was classified into 4 types.TypeⅠand TypeⅡare normal.TypeⅢand TypeⅣare abnormal.Main Outcome Measures The type of tear feming.Results TFT showed that tear ferning was de- creased in conjunctivochalasis group(TypeⅢand TypeⅣoccupied 61.7%).The difference between conjunctivoehalasis and normal control group was significant(P

Objective To investigate the clinical efficacy of Gamma knife treatment on patients with functional pituitary prolactinoma(PRL)and its endocrine response.Method We retrospectively analyzed the clinical data of 135 cases of functional pituitary prolactinoma treated with Gamma knife in our hospital from Oct 1994 to Jan 2008.All patients were divided into 3 groups:group A(a central dose of 50 to 60 Gy,a marginal dose of 20 to 30 Gy);group B(a central dose of 40 to 50 Gy,a marginal dose of 15 to 25 Gy)and group C(a central dose of 30 to 40 Gy,amarginal dose of 12 to 20 Gy).The dose in the optic nerves of the 3 groups was under 9 Gy. Results After treated with Gamma knife,partial remission(PR)of the clinical symptoms appeared in 90 patients(66.7%);complete remission(CR)of those was showed in 35(25.9%)and no change of those appeared in 10(7.4%).No significant difference was found between age and both sex and tumor sizes in the 3 group(P<0.05).Different normal PRL rates was concluded by using different doses of Gamma knife(F=8.604,P=0.000).Pairwise comparison indicated that high dose of Gamma knife resulted in high PRL normal rates with statistical significance (P<0.05). Conclusion Gamma knife treatment used in patients with functional pituitary adenoma can not only control the growth of tumor,but also improve the dysfunction of endocrine,which should be adopted as the first choice for clinical treatment of functional pituitary prolactinoma.
