AIM:To observe and compare clinical effects of coaxial 1. 8mm microincision phacoemulsification and 3. 2mm small incision phacoemulsification.
●METHODS:A total of 117 eyes of 85 patients with age-related cataract in our hospital were divided randomly into two groups:43 patients (59 eyes) in the coaxial 1. 8 mm microincision cataract surgery group ( C - MlCS ) , 42 patients (58 eyes) in the coaxial 3. 2 mm traditional small incision cataract surgery group (C-SlCS). A total of 117 eyes were received phacoemulsification with intraocular lens implantation. Uncorrected visual acuity was recorded preoperatively and postoperatively at 1, 7, 30 and 90d. The effective phacoemulsification time and average ultrasound energy were recorded in surgery. Corneal endothelial cell and corneal topography were recorded preoperatively and postoperatively at 90 d.
●RESULTS:Uncorrected visual acuity ( logMAR) was no overall statistical significance difference between C-MlCS group and C-SlCS group (P>0. 05), but was significant statistical difference in different time-point within both groups(P<0. 05). Uncorrected visual acuity in different time-point had nothing to do with corneal wound size in cataract surgery(P>0. 05). On the 1 day after surgery, uncorrected visual acuity was 0. 16±0. 11 in C-MlCS group and 0. 22±0. 18 in C-SlCS group(P<0. 05). AVE was (7. 00± 2.72)% in C-MlCS group and (6. 16±3. 16)% in C-SlCS group (P>0. 05). EPT was (3. 09±1. 61)s in C-MlCS group and (3. 20±1. 92)s in C-SlCS group (P>0. 05). At 90 d after surgery, corneal endothelial cell loss percentage was (5. 81±2. 28)% in C-MlCS group and (5. 69±2. 38)% in C-SlCS group (P>0.05), SlA was (0.35±0.11) Din C-MlCS group and (0. 61±0. 13) D in C-SlCS group (P<0. 05).
● CONCLUSION: Compared with coaxial 3. 2mm traditional small incision cataract surgery, 1. 8mm coaxial microincision cataract surgery can get earlier visual rehabilitation and significantly reduce SlA. The coaxial 1. 8mm microincision cataract surgery is safe, effective and deserves further clinical applications.

OBJECTIVETo establish an HPLC-DAD/ESI-MS method for quickly identifying chemical constituents in diterpene lactone effective fraction of Andrographis panniculata and to study its pharmacodynamics.

METHODThe separation was performed on an Agilent SB-C18 column (2.1 mm x 150 mm, 5 μm) with a mobile phase of acetonitrile (A) and water (B). The flow rate was maintained at 0.4 mL x min(-1) and detection wavelength was set at 205 nm. The samples were analyzed in positive ion mode, and mass scan range was m/z 50-1 000. Using two kinds of tumor cell lines made living animal models, and studied preliminary pharmacodynamics on anti-tumor aspect.

A strain of P. Aeruginosa,which was seperated from clinical environment,shows a special characteristic. It keeps normal short rod shape when cultured at 37℃, however,it forms filament without pyocyanin producing when cultured at 25℃ overnight. The filaments will divide and form short rods, simultaneously, produce pyocyanin when culture time is prolonged to over 72h or culture temperature is raised to 37℃. The preliminary study indicates that this phenomenin has nothing to do with nutritive conditions and could the inbluenced by inoculating density and irradiating with ultraviolet rays The absence of pyocyanin was not the cause of filamentous formation by the test results.

Objective To explore the effects of recombinant human hormone(rhGH) on the plasma total protein,plasma albmin,healing of Wound surfaces in patients with the second degree burns wound.Methods 38 pa- tients with the second degree burns wound were divided into treatment group and control group randomly.All the patients were subject general.19 patients in the treatment group were given rhGH in a dose of 0.2U/kg for 14 days beginning from postoperative 5 days.The plasma total protein concentration,plasma albumin concentration,healing rat of wound surface and scar of patients of the two group were compared.Results The plasma total protein concen- tration plasma albumin concentration of the treatment group were significantly in creased,the scar hyperplasia of the treatment group were significantly mitigated and the healing time of wound surfaces of the treatment group were sig- nificantly shortened.Conclusion rhGH is found to promote protein anabotism and shorten the healing time of wound surfaces and mitigate the scar hyperplasia patients with the second degree burns wound.

OBJECTIVETo detect the loss of heterozygosity (LOH) in esophageal squamous cell carcinoma and adjacent high-grade squamous dysplasia, and to evaluate possible tumor suppressor genes in the development and progression of invasive malignancy.

METHODSLOH was detected in normal esophageal mucosa, high grade squamous dysplasia and esophageal squamous cell carcinoma using microdissection and polymerase chain reaction technology. The changes of LOH at seven microsatellite markers and the relationship between LOH rate and clinicopathologic parameters were analyzed.

RESULTSIn high grade squamous dysplasia, LOH was detected at D13S802 (40%), D13S267 (32%), D13S221 (31%), D9S942 (30%), D17S520 (24%) and D9S171 (33%). However, D17S1798 LOH was not detected. In invasive squamous cell carcinoma, LOH was detected as follows: D13S267 (71%), D13S802 (58%), D17S520 (55%), D13S221 (45%), D9S942 (43%), D9S171 (33%) and D17S1798 (11%). The frequency of LOH in the seven microsatellite markers, the pathologic grade, clinical stage and occurrence of lymph node metastasis did not show any statistically significant correlation (P > 0.05).

CONCLUSIONSThe progression from normal squamous epithelium to high grade squamous dysplasia and subsequently to invasive squamous cell carcinoma of the esophagus was associated with accumulation of genetic errors. Possible tumor suppressor genes related to the development of esophageal squamous cell carcinoma may exist near D13S802 (13q12.12). Possible tumor suppressor genes near D13S267 (13q13.1), D17S1798 (17p13.3) and D17S520 (17p13.1) may be related to the progression of esophageal squamous cell carcinoma.

OBJECTIVETo analyze the somnipathy related factors in elderly patients with stroke and to compare effects of traditional Chinese medicine and estazolam on sleep and the followed nervous function.

METHODSThe somnipathy related factors in 336 elderly patients with stroke, 221 accompanied with somnipathy and 115 with normal sleep, were studied and analyzed. Moreover, the 221 patients with somnipathy were assigned to two groups, 112 in the treated group treated with TCM according to syndrome differentiation, and 109 in the control group treated with estazolam. Changes of scores rated by neurological deficit scale (NDS), sleep dysfunction rating scale (SDRS), Hamilton anxiety rating scale (HAMA), Hamilton depression scale (HAMD), and treatment emergent symptom scale (TESS) were observed before and after treatment.

RESULTSThe occurrence of somnipathy in patients with cerebral hemorrhage was significantly higher than in those with cerebral infarction; it was higher in patients with lesion in brain stem, cerebral hemisphere (frontal lobe), or basal ganglion than in those with lesion in other sites; and patients with severe neurological deficit were more liable to having somnipathy. TCM showed a significant effect in improving the insomnia symptoms in patients, with the total effective rate reaching 81.25% (91/112), which was higher than that in the control group, 65.14% (71/109, P < 0.01). Along with the improving of sleep, marked recovery of the nervous function was shown in both groups, with NDS score reduced significantly (P < 0.05).

CONCLUSIONThe occurrence of somnipathy in stroke patients was closely related with the property and site of lesion, and the neurological deficit degree of patients. Better sleep is surely favorable for recovery of the nervous function, and TCM shows a favorable efficacy on somnipathy.
