AIM: To observe the effect of compound anisodine injection combined with yi-qi-tong-luo acupuncture, hot compress and massage for blepharospasm.
METHODS: Selected in our hospital, 60 cases (78 eyes) with blepharospasm were randomly divided into two groups, 30 cases 39 eyes in each group. The observation group were treated with compound anisodine injection combined with yi - qi - tong - luo acupuncture treatment, and supplemented by hot compress and massage, while the control group only with compound anisodine injection. We compared the treatment effect of the two groups.
RESULTS: In the observation group, 38 eyes were clinically effective, 1 eye was invalid, 35 eyes marked, the total effective rate was 97%, the markedly effective rate was 90%; in control group, 32 eyes were the clinically effective, 7 eyes invalid, 23 eyes marked, the total effective rate was 82%, the markedly effective rate was 59%; the total effective rate and markedly effective rate of observation group were higher than those of the control group with statistical difference (P<0. 05). The recurrence rates of the two groups were 5% and 34%, respectively, and the recurrence rate of the observation group was significantly lower than that of the control group ( P <0. 05).
CONCLUSION: The compound anisodine injection combined with yi - qi - tong - luo acupuncture, hot compress and massage for blepharospasm, can significantly improve the efficiency of treatment, with higher effective rate and lower recurrence rate, compared with using compound anisodine alone.

AIMTo investigate the effect of sodium ferulate (SF) on glycerol-induced renal injury.

METHODSGlycerol solution 50% was injected intramuscularly to establish a model of acute tubular necrosis in mice. SF was administered intraperitoneally at the dose of 100-200 mg.kg-1 at the beginning of establishing the model and its effect was observed by monitoring renal function, antioxidative functions and renal pathologic histology.

RESULTSAt 6 and 72 h after glycerol injection, SF treatment (100-200 mg.kg-1) showed significant and dose-dependent antagonistic actions on the increment of blood urea nitrogen (BUN), creatinine (Cr), and N-acetyl-beta-glucosaminidase (NAG) induced by glycerol. The increase of renal malondialdehyde (MDA) content and the decrease of glutathione content, glutathione peroxidase (GSH-Px), glutathione S-transferase (GST), catalase (Cat) and superoxide dismutase (SOD) activities resulting from glycerol injection were remarkably inversed by SF at the dose of 200 mg.kg-1. Meanwhile, improvement of the renal histology was observed as well.

CONCLUSIONSF showed beneficial effect on glycerol-induced acute tubular necrosis due to its antioxidative action.

AIM: To evaluate the effect of probing of lacrimal passage combining injecting of US-produced TobraDex eye ointment for the treatment of chronic dacryocystitis.METHODS: For 127 cases (129 eyes) of chronic dacryocystitis, first the pyoid secretion gathered in the lacrimal sac was dashed out, and some TobraDex was injected in the middle of the lacrimal passage once per day, repeated for several times. The lacrimal passage was probed when the secretion of lacrimal sac disappeared essentially. The lacrimal passage and immit TobraDex eye ointment was used once every two days, repeated for 3-4 times.RESULTS: In 126 cases (128 eyes) the lacrimal passage was dredged. Only one case (1 eye) the youthful patient did not recover for the opening ectopia of lacrimonasal duct.During the 3mo-1a random visit the chronic dacryocystitis did not recrudesce in the cases of lacrimal passage dredging.CONCLUSION: It is simple and safe to use the probing of lacrimal passage combining injecting of US-produced TobraDex eye ointment to treat the chronic dacryocystitis. This method has good curative effects and can keep the normal physiological structure of lacrimal passage. It does not need any expensive medical equipment and cost less, therefore is advisable for patients.

In order to find a method suitable for purifying large amount of CD34(+) cells, from 5 cases who accepted autologous peripheral blood stem cell transplantation, CD34(+) cells were collected and enriched by using Isolex 300i (Nexell). Phenotypes were detected by flow cytometry and the biological viability were assayed by the colony-forming experiments and cell expansion experiment in vitro. The results showed that the number of mononuclear cells first collected was about (3.5 - 6.0) x 10(10) and (0.55 - 1.2)% of cells were CD34 positive. The number of positive production was about (2.0 - 3.0) x 10(8); the CD34(+) cells purity was (75 - 85)% and the yield was (40 - 65)%. The CD34(+) cells of positive production could expand up to 2 - 3 times when cultured with SCF + IL3 + FL + TPO + EPO in vitro. The results of colony-forming experiments demonstrated that the CD34(+) cells collected has enough colony-forming ability. All results showed the enriched CD34(+) cells with biological viability. In conclusion, the CD34(+) immunomagnetic isolation apparatus Isolex300i is suitable to clinical application for a large amount of CD34(+) cell enrichment.

Objective To observe the protein and gene expression of immunoglobulin binding protein (BiP) in the femur of fluoride-treated rats, and preliminarily study the possible role of endoplasmic reticulum stress in the pathogenesis of skeletal fluorosis. Methods Sixty Wistar rats were divided into 4 groups according to body weight, n =15. The control and low-calcium groups were fed with normal diet(0.79％ calcium) and low-calcium diet(0.063％ calcium), respectively, and both drank tap water(fluoride concentrations ＜ 1 mg/L). High-fluoride and coexpesure to low-calcium groups were fed with conventional feed (0.79％ calcium) and low-calcium diet (0.063％ calcium), respectively, and both drank tap water containing sodium fluoride (sodium fluoride concentration of 221 mg/L). During experimental period, rats were measured body weight once a week with a stand diet and water available ad libitum. The experiment lasted for 12 weeks. The immunohistochemical and reverse transcription polymerase chain reaction(RT-PCR) techniques were used to detect the protein and gene expression of BiP in the femur of fluoride-treated rats and control subjects. Results The bone mineral contents of high fluoride, lowcalcium and coexposure groups[(0.131 ± 0019), (0.097 ± 0.011 ), (0.083 ± 0.007)g/cm] were lower than those of the control group[(0.159 ± 0.029)g/cm, all P ＜ 0.05]; the bone mineral density of low calcium and coexpesure to fluoride group[(0.243 ± 0.018), (0.223 ± 0.022)g/cm2] was lower than that of the control group[(0.296 ± 0.046)g/cm2, all P ＜ 0.05]. The immunohistochemical staining showed that the anti-BiP antibody positive osteoblasts were significantly increased in the low calcium diet and coexposure to fluoride groups than that in the control, and coexposure to fluoride elevated the positive cells than that in only low calcium diet group. The mRNA expression of osteopontin(OPN) and osteocalcin(OCN) in coexposure to fluoride with low-calcium group(1.36 ± 0.20, 1.31 ±0.11 ) was higher than that of the control groups (0.82 ± 0.16, 0.85 ± 0.15, all P ＜ 0.05) ; moreover, OPN expression significantly increased in this group than that of the only high fluoride group (0.97 ± 0.29, P ＜ 0.05). The mRNA expression of BiP in the low calcium and coposure to fluoride group (1.38 ± 0.24,1.35 ± 0.12) was significantly higher than that of the control group ( 1.14 ± 0.06, all P ＜ 0.05 ). Conclusions Higher fluoride or coexposure to low calcium diet stimulates the gene and protein expression in rat femur BiP, indicating that varying degrees of endoplasmic reticulum stress is likely involved in the pathogenesis of rat skeletal fluorosis.
