?AIM:To study the clinical value of non-steroidal anti-inflammatory drug in adjuvant treatment of intravitreal triamcinolone acetonide ( IVTA ) for macular edema caused by retinal vein occlusion ( RVO) .?METHODS: Forty - eight eyes in 48 patients were randomly divided into trial and control group ( 24 eyes each ) in this prospective study. In the trial group, additional pranoprofen drops was administered from 1d before IVTA to 30d after injection. Central foveal thickness ( CFT ) was measured with optical coherence tomography ( OCT ) . Available documents of best corrected visual acuity ( BCVA ) , CFT, intraocular pressure and complications pre- and post-injection at 3d, 1,2wk, 1 and 3mo were evaluated.?RESULTS: After IVTA, BCVA was improved in both groups at different levels; but there was no statistically significant between two groups at each time point ( P>0. 05). The CFT values were 629 ± 43μm vs 605 ± 57μm before IVTA in the trail vs control groups (P>0. 05). The values were 432±74μm vs 511±32μm (t=7. 533, P<0. 05), and 275±54μm vs 379±29μm (t=13. 212, P<0. 05) of the trial vs control groups at 1 and 3mo after IVTA, respectively. Ocular hypertension occurred in 5 eyes after injection in trail group, and was controlled with anti-glaucoma medication and one eye with filtration surgery. Progression of cataract was noted in 3 of 35 phakic eyes and cataract surgery was performed in 2 eyes at 4-12mo after injection in trail group. Progression of cataract was noted in 4 eyes and cataract surgery was performed in 2 eyes at 4- 12mo after injection in control group. No retinal detachment and endophthalmitis happened during the whole period of follow-up.?CONCLUSION: Application of non - steroidal anti -inflammatory eye drops in perioperative period can be useful to improve the outcome of IVTA for macular edema, which needs further evaluation.

ObjectiveTo explore the relationship of circadian distribution of acute myocardial infarction with AMI location and ST segment changes in elderly patients.MethodsThe time of infarction, its anatomic location, changes of ST segment, and coronary angiography were studied in 909 elderly patients with acute myocardial infarction (AMI) ( 412 with anterior AMI and 423 with inferior AMI) admitted to our coronary care units from January 1996 to January 2006.ResultsThe onset of inferior myocardial infarction were more frequent between midnight and 6AM than other periods of the day (n=138/423,32.6% of all inferior myocardial infarction patients, P<0.01). The onset of anterior myocardial infarction were more frequent between 6AM and noon than other periods of the day (n=156/412, 37.9% of all anterior myocardial infarction patients, P<0.01). Coronary angiography was performed in 789 patients (86.8%, 516/909).118 cases of them with inferior infarction occured between midnight and 6AM, including 85.6% of them were due to right coronary artery occlusion and 14.0%(17/118) of them were due to left coronary artery occlusion (P<0.01).275 cases of them with inferior infarction oecured between 6AM and midnight, including 52.2% (149/275) of them were due to right coronary artery occlusion and 45.8% of them were due to left coronary artery occlusion (P>0. 05). The onset of inferior myocardial infarction between 6AM and noon was the most frenquent in patients with ST segment elevation (44.0%, 263/644), while the onset of inferior myocardial infarction between midnight and 6 AM was the most frenquent in patients with non-ST segment elevation (36.6%,96/265). ConclusionsThe frequency of AMI at night is higher in elderly patients with ST segment elevation than in elderly patients with non-ST segment elevation.AMI at night is usually due to right coronary artery occlusion, which suggests that a protective role of sleep may be limited to left coronary artery -related events and AMI of non-ST segment.

OBJECTIVETo study the effect of panax notoginsenosides (PNS) on the proliferation of hematopoietic progenitor cells (HPC) in mice with immune-mediated aplastic anemia.

METHODSBalb/c mice model of immune-mediated aplastic anemia was established by radiation with sublethal dose of 60Co following the intravenously infusing lymphocytes of DBA/2 mice. Model mice in the treated groups were treated separately with high, middle and low dose of PNS, 3.2 mg, 1.6 mg and 0.8 mg per day respectively by intraperitoneal injection. Model mice in the control group and normal mice in the normal control group were treated with normal saline. The peripheral white blood cell (WBC) count and pathological examination of bone marrow were carried out 12 days later, the bone marrow was taken to be incubated in semi-solid culture system for observing proliferation of HPC.

RESULTSPNS could (1) increase peripheral WBC count: as compared with that in the model control, WBC in the high, middle and low dose PNS groups was raised by (34.3 +/- 2.9)%, (29.2 +/- 1.7)% and (14.5 +/- 1.6)% respectively, P < 0.01 and P < 0.05; (2) improve the bone marrow inhibition: pathological examination showed in the model group, the hematopoietic structure was destroyed and replaced by fatty tissue, while in the PNS treated groups, the structure of marrow was rather complete and filled with abundant hematopoietic cells; (3) promote the proliferation of HPC: as compared with the model group, the colony formation of CFU-GM were increased by (64.4 +/- 2.8)%, (67.3 +/- 2.4)% and (21.9 +/- 1.8)% respectively and that of CFU-E increased by (31.9 +/- 3.6)%, (20.7 +/- 2.4)% and (12.8 +/- 2.6)% respectively in the three PNS treated group (P < 0.01 and P < 0.05).

CONCLUSIONPNS could enhance hematopoiesis by promoting proliferation of CFU-GM and CFU-E progenitors so as to improve the hematopoietic function in mice of immune-mediated aplastic anemia.

To evaluate the value of silicone intubation and ring-fixed method in canalicular laceration.
●METHODS: A retrospective study of 36 cases with laceration of lacrimal canaliculus. For all the patients, microscope was used to find the broken ends of the lacrimal canaliculus, and then straight insertion was performed to the distant and near broken ends through the upper and lower lacrimal points, then passed the dacryocyst to insert nasolacrimal canal and ended up in inferior nasal meatus. Thus, clinical data about forming annular support to treat laceration of lacrimal canaliculus was presented here.
● RESULTS: All 36 patients with traumatic canalicular laceration were anastomosed successfully and all patients healed without infection. The surgery went well, intubation was smoothly, all patients were followed - up for another 6mo after the stent was removed. The accidental fall off of the stent was not observed during the follow - up. During the follow - up 10 - 18mo after extubation, when the stent was removed, 32 cases (88. 9%) recovered to normal lacrimal drainage function;4 cases ( 11. 1%) remained epiphora with obstructed lacrimal passage. All cases were no lower eyelid ectropion.
●CONCLUSlON: For the patients with inferior canalicular laceration, the silicone intubation and ring-fixed method is effective, low irritation and less complication.

Abstract: Objective To analyze the antimicrobial resistance rate and risk factors of multi drug resistant organisms (MDRO) in bloodstream infection for rational treatment. Methods　A total of 696 cases of bloodstream infections of Staphylococcus aureus, Enterococcus, Enterobacteriaceae (excluding Salmonella and Shigella), Pseudomonas aeruginosa and Acinetobacter in our hospital from 2017 to 2021 were selected, and 711 pathogenic strains were isolated from their whole blood samples. The antimicrobial resistance rates of various multi drug resistant strains were analyzed and the risk factors of MDRO infection were analyzed. Results　696 non repeated cases were screened out from 13 187 whole blood culture specimens, with a positive rate of 5.3%, and a total of 711 blood influenza pathogens were detected, among them, 350 strains of MDRO were detected with a detection rate of 49.23% (350/711). Among the pathogenic bacteria of bloodstream infection, Escherichia coli was the most, with 277 strains accounting for 38.96% (277/711), of which 201 strains were MDRO, accounting for 57.43% (201/350); followed by Klebsiella pneumoniae and Staphylococcus aureus, with 155 strains accounting for 21.80% (155/711) and 89 strains accounting for 12.52% (89/711), among which 43 strains of Klebsiella pneumoniae MDRO accounted for 12.29% (43/350) and 38 strains of Staphylococcus aureus MDRO accounted for 10.86% (38/350). The change trend of the three pathogens during 2017-2021 was not obvious. The drug sensitivity test showed that Escherichia coli and Klebsiella pneumoniae were highly resistant to cephalosporins and fluoroquinolones, and the drug resistance rate of aminoglycosides was relatively low. They had almost no resistance to cephalosporins and carbapenems. Staphylococcus aureus has a high resistance rate to lincomycin and macrolides, but no resistance to oxazolidinone, glycopeptides and glycylcyclins. There were 350 cases of MDRO infection and 361 cases of non MDRO infection. Univariate analysis showed that the age, sex, cardiovascular and cerebrovascular history, renal insufficiency, lung disease, hypoalbuminemia, hepatobiliary disease, electrolyte disorder and anemia of the patients had no statistical significance in MDRO infection (P>0.05); diabetes, urinary tract infection, surgical operation and burn were the influencing factors of MDRO (P<0.05). According to logistic analysis, diabetes, urinary tract infection, surgical operation and burn were the risk factors of MDRO infection (P<0.05). Conclusion　The infection of MDRO in patients with bloodstream infection is serious, and early prevention and control should be paid attention to, and the principle of graded use of antibiotics should be strictly observed, and the rational application should be carried out to actively and effectively control the production of MDRO.

The cupping spot is considered as one kind of skin change due to cupping treatment. With literature regarding cupping spot, the influencing factors and value of cupping spot in clinical diagnosis and treatment were analyzed, which could make a further exploration on the action mechanism of cupping treatment. The literature showed that the formation of cupping spot was related with cupping temperature, pressure, cup-retaining time, cupping area, individual difference and health condition, etc; cupping spot had the ability to assist diagnosis, prevent disease, cure disease and evaluate clinical efficacy. Previous studies on cupping spot have already made some progress, and played a positive significance on finding cupping rule and studying its mechanism. However, the research for this area is still in the primary stage, which needed deeper study to reveal scientific connotations of cupping spot.
