AIM:To analyze the 34 cases of patients with diagnosis of lacrimal duct disease, to explore the cause and clinical characteristics of lacrimal duct inflammation, and to study the common misdiagnosis to improve the diagnosis rate, to provide clinical experience for medical workers.
METHODS: A total of 34 eyes of 34 patients were selected from 2011-06 to 2015-06 to our hospital for lacrimal duct incision. Clinical data of patients including age and gender distribution, eye and lesion location, duration, canaliculitis clinical symptoms and previous misdiagnosis were collected. The operation of lacrimal duct was carried out, and the secretion of lacrimal secretion was checked.
RESULTS:Patients over the age of 40 accounted for 77%of the population, men accounted for 23. 5%, women accounted for 76. 5%. Left eye in 15 cases, right eye in 19 cases, and were monocular onset, 26 cases ( 76%) of patients with lower lacrimal duct inflammation. Clinical symptoms: increased secretion, canthal conjunctival congestion, swelling, lesion location around the lacrimal puncta swelling and tenderness, slightly raised, epiphora, foreign body sensation. The culture results Showed 34 cases of discharge inspection. A total of 20 cases were fungal growth, 6 cases of bacterial growth rate were 59%, 18%, and 8 cases were not detected, 10 cases of lacrimal duct stone were found by pathological examination. There were 3 cases of Aspergillus, 5 cases of Candida, 2 cases of actinomycetes, 4 cases found in Gram staining microscope. Misdiagnosis of canaliculitis for other eye diseases, including 12 cases of chronic dacryocystitis, 8 cases of chronic conjunctivitis, 6 cases of acute conjunctivitis, stye in 4 cases, the misdiagnosis rate reached 88%.
CONCLUSION:In the middle and old aged people, the lacrimal duct is more than that of the male. The main pathogenic bacteria causing lacrimal duct infection may be fungi, which can be treated with anti-fungal drugs. For the removal of the lacrimal duct stone, we should distinguish the types of pathogenic bacteria for the treatment of the disease. In the case of misdiagnosis, the clinical manifestations of different clinical manifestations from the lacrimal duct infection and other diseases of the eye should be carefully examined and carefully treated.

Polypoidal choroidal vasculopathy(PCV) is a common disease of the retina,the disease is more found in colored race.In China,the mainly nosogenic population is the female about 60 years old.The pathogenesis of PCV is unknown and there is no specific medicine at present.The funduscopic present is orangered lesions,bleed and exudation.Indocyanine green angiography(ICGA) could make a definite diagnosis of PCV.In recent,the main treatment of PCV includes photodynamic therapy,intravitreal anti-VEGF therapy,surgery for treatment of complications and combined therapy.We review the treatment and diagnosis of PCV,and propose the further research direction.

AIM: Currently available anti-scarring regimens for glaucoma filtration surgery have potentially blinding complications and safer alternatives would be beneficial. This experiment is to investigate the effect of TGF-β2 antisense oligodeoxynucleotide on differentiation, proliferation of subconjunctival fibroblast following glaucoma filtration surgery.METHODS: Glaucoma filtration surgery were performed on both eyes of 28 rabbits. TGF-β2 antisense oligodeoxynudeotide was subconjunctivally injected in the right eyes (A group), and TGF-β2 missense oligodeoxynucleotide (B group)or PBS(C group) was used at the same method in the left eyes as controls. Rabbits were killed at 4,7,14 and 28 days after surgery. Intraocular pressure (IOP), bleb characteristics were recorded at different time point. Subconjunctival fibroblasts were examined by immunohistochemistry and electron microscopy.RESULTS: The IOP of rabbits in group A was significantly lower at 14 days (6.74± 1.18 mmHg) and 21 days (8.15± 1.97mmHg) after operation than the IOP in group B (8.53± 1.04,9.72± 1.09 mmHg)(P ＜0.01) and group C(8.79± 1.21, 9.43±1.27 mmHg) (P ＜0.05). The mean bleb survival time was longer (17.2 days) in group A than that of group B (14.5 days) and group C (13.5 days)(P＜0.05). The population of the cells expressing α -smooth muscle actin(α -SMA) and proliferating cell nuclear antigen (PCNA) was significantly reduced in group A compared with the group B and C. The ultrastructure of fibroblast was not altered by TGF-β2 anti-sense oligodeoxynucleotide.CONCLUSION:TGF-β2 antisense oligodeoxynucleotide can prevent the scar formation after glaucoma surgery by inhibit the differentiation and proliferation of subconjunctival fibroblast. It could be a potentially useful anti-scarring alternative for the prevention of late surgical failure.

OBJECTIVE:To evaluate the status quo of the application of Chinese traditional medicines andthe problemslie in the development of the application of Chinese traditional medicine.METHODS:The Chinese traditional medicines used in outpatients from Apr.2006to Apr.2007in our patient were analyzed statistically in respect of the consumption sum,con-sumption quantity and drug category.RESULTS:Leading the list in terms of consumption quantity in the outpatient depart-ment were heat-clearing drugs,detoxicating drugs,dampness-drying drugs and haemostatics.The utilization of Chinese traditional medicines in outpatients was standard on the whole,but there were still some irrational phenomena.CONCLU-SION:To enhance the curative efficacy of Chinese traditional medicines and standardize their use,the co-effort of both hospital staff and the society is much needed.

BACKGROUND: Perforin gene (PRF1) mutations have been reported in patients with lymphoma, but the prevalence and characteristics of PRF1 mutation have not been identified in Chinese patients with lymphoma. METHODS: Seventy-seven patients with lymphoma, including 6 patients with Hodgkin lymphoma and 71 patients with non-Hodgkin lymphoma, were recruited. DNA samples from peripheral blood were used for PRF1 mutation detection by the PCR-sequencing method. RESULTS: Eleven novel PRF1 mutations were found in 8 of the 77 patients with lymphoma. Biallelic or compound monoallelic missense mutations in 3 patients indicated the severe impairment of perforin function, monoallelic missense mutations in 3 patients possibly contributed a genetic predisposition to malignancies, and synonymous mutations in 2 patients showed unknown significance. CONCLUSIONS: The frequency of EBV infection was similar in lymphoma patients with PRF1 mutations and those without the mutations. The same PRF1 mutations were also found in DNA samples from nails or hair follicles from 4 patients with PRF1 mutations, suggesting that these mutations may be of germ-line origin.

OBJECTIVE:To investigate the effects of Cangfu daotan decoction combined with Clomiphene citrate capsule on sex hormone level and endometrial receptivity in patients with polycystic ovary syndrome (PCOS) combined infertility. METH-ODS:A total of 116 PCOS patients with infertility in the First Affiliated Hospital of Guiyang College of TCM from Jan. 2014 to Dec. 2014 were divided into observation group and control group according to random number table,with 58 cases in each group. Both groups received hormone regulation therapy since the fifth day of menstruation. Control group was given Clomiphene citrate capsule 50 mg,qd;observation group was additionally given one dose of Cangfu daotan decoction,400 mL after decocted with wa-ter,bid,on the basis of control group. Both groups were treated for 3 cycles of menstruation. The levels of serum sex hormone (E2,LH),endometrial thickness(Em),endometrial spiral arterial pulsatility index(PI)and resistance index(RI)were compared between 2 groups before and after treatment. The ovulation rate and pregnancy rate were compared between 2 groups after 1-year follow-up. RESULTS:Before treatment,there was no statistical significance in E2,LH,Em,PI or RI between 2 groups (P>0.05). After treatment,the levels of E2 and LH as well as Em in 2 groups were increased significantly,while PI and RI were de-creased significantly;the observation group was significantly better than the control group,with statistical significance(P<0.06). After 1-year follow-up,there was no statistical significance in ovulation rate between 2 groups (P>0.05). The pregnancy rate of observation group was 41.38％,which was significantly higher than that of control group (22.41％),with statistical significance (P<0.05). CONCLUSIONS:Cangfu daotan decoction combined with Clomiphene citrate capsule can effectively regulate serum sex hormone levels of PCOS patients with infertility,and improve endometrial receptivity so as to increase pregnancy rate.
