Carotenoids play an important role in regulating the hydrogen production of hydrogen-producing Rhodobacter sp. The carotenoids of hydrogen-producing Rhodobacter sp. grown in acetate medium were extracted by using acetone-methanol (7∶2,V/V) solvent and were separated by using thin-layer chromatography on silica-gel plate. The qualitative and quantitative of the carotenoids were analyzed by spectrometry. The results showed that the carotenoids were completely extracted three times with acetone-methanol (7∶2,V/V) in two hours. The ultrasonication had little effect on yield of carotenoids. The yield of carotenoids was 2.81mg/g wet cell. There were 4 spots on the silica-gel plate in the order of yellow, red, light red and light yellow. Yellow spot and red spot were the dominant composition of carotenoid in Rhodobacter sp. The spectrometry data showed that the yellow and red component might be the spheroidene and spirilloanthin respectively.

ObjectiveTo explore the relationship between thermography patterns and the clinical features of thalamus hemorrhage in the recovery period. MethodsTwo hands skin temperature of 32 patients with thalamus hemorrhage were measured with infrared heat radiation imaging 1 month after the stroke. Results21(66%) of 32 patients showed different imaging patterns between the affected limbs and the healthy sides. Of the 25 palsy patients, 18 (72%) showed abnormal images, just 3 of 7(42.6%) patients with normal muscle force showed abnormal images, and the difference was significanct(P<0.05). There was no relation between sensory disorder and imaging pattern. Patients with hematom lager than 10 millilitre showed more abnormal images than those with hematom under 10 millilitre(P<0.05). Patients with a course within 3 months had a tendency to show hot pattern, while those with a course beyond 3 month showed cold pattern. Conclusion There are certain relations between thermograpy patterns and the symptoms, signs of thalamus hemorrhage.

Mutagenesis and screening of hydrogen-producing photosynthetic bacteria,Rhodobacter sp.R7 strain,was investigated by using the combination mutation of ultraviolet ray and LiCl and layer plating methods.A carotenoid mutant named R726 strain was obtained.The plate phenotype properties in carotenoid mutant were different from that of parent strains.Living cells spectra showed that absorption peak of 550 nm was appeared in carotenoid mutant,but not in parent strain.The absorption spectra of extraction of pigment further confirmed the difference of carotenoid composition between the mutant and parent strains.The result of TLC on silica gel plate showed that mutant has a lack of yellow carotenoid composition which occurs in parent strain.H_2 productivity and biomass in carotenoid mutant was higher than that of parent strain.These results revealed that mutant has a modified carotenoid biosynthesis pathway.

OBJECTIVETo probe into effect of scalp acupuncture combined with sports therapy on movement function of limbs in the patient of poststroke hemiplegia.

METHODSOne hundred and twenty cases of poststroke hemiplegia were randomly divided into an observation group and a control group, 60 cases in each group. The observation group were treated by scalp acupuncture and the control group by simple sports therapy. The movement function of limbs were assessed by Fugl-Meyer rating method and Barthel index.

RESULTSThe movement function of limbs and ability of daily life after treatment in the observation group improved very significantly as compared with the control group (P < 0.01).

CONCLUSIONScalp acupuncture combined with sports therapy can promote recovery of the movement function of limbs in the patient of poststroke hemiplegia.

Objective: To study the examination of coronary sinus (CS) and blood flow by transthoracic echocardiography(TTE) and transesophageal echocardiography(TEE).Methods: Thirty patients with supraventricular tachycardia were studied by TTE and TEE. The CS was visualized using modified 4 chamber view. The position of the probe was optimized until the coronary sinus with its ostium into the right atrium could be visualized. CS flow recordings were performed by TEE with Doppler sample volume placed in the CS within a distance of no more than 10 mm from its ostium. Results: In all patients the angle between the doppler beam and the long axis of the CS was <30°. The CS was fully displayed in 18 patients by TTE and 28 patients by TEE. The length and width of the CS were (16.53±2.57) mm and (4.51±1.30) mm by TTE, (24.11±2.46) mm and (5.06±0.97) mm by TEE.The CS flow was characterized by biphasic flow.Its flow velocity was (39±7.8), (31±6.1) and (21±4.7) cm/s respectively. The CS flow velocity-imeintegral was(43±11.6),(43±13.0),(27±8.2) cm/s. Conclusion: Echocardiography is reliable for detecting CS and its flow. TTE is more feasible for detecting CS and its flow than TEE.

To investigate the influence of stainless steel(SS)and titanium oxide(Ti-O)thin films on the cytokine released by en-dothelial cells.Ti-O films were prepared by unbalanced magnetron sputtering deposition system(UBMS).Human umbilical vein en-dothelial cells(HUVECS)were isolated and seeded on SS and Ti-O materials.Nitride oxide (NO)and monocytc chemotactic protein one(MCP-1)concentrations were determined in the supematants with enzyme linked immunosorbent assay(ELISA)at 1,3 and 5 days after culture,and the morphology of the cells was observed using scanning electron microscopy(SEM).The results showed that the similar amount of HUVECs was presented in SS and Ti-O culture.But HUVEC had better morphology on Ti-O film than SS.The NO and MCP.1 test also showed that HUVECs on Ti-O film had a better bio-function than SS.It is concluded that Ti-O film as a biomaterial may have a better endothlieal compatibility,which can be used to enhance the endothelialization.

·AlM: To explore the treatment effect of initial lacrimal passage irrigation and probing in neonatal dacryocystitis. · METHODS: ln this retrospective case series study, 224 outpatients ( 256 eyes ) with neonatal dacryocystitis were selected from January 2012 to December 2012 in our hospital.The patients were divided into 5 groups ( 1 ~3mo, 4~60mo, 7 ~9mo, 10 ~12mo and >12mo).lnitial lacrimal passage irrigation and probing were operated, the therapeutic effect of different groups were compared. ·RESULTS:ln this study, 256 eyes of 224 cases, 242 eyes (94.5%) were cured and 14 eyes ( 5.5%) were failed. Bony nasolacrimal duct obstruction happened more obviously in children aged more than 10mo with lower cure rate.More probing was required with the children aged (Spearman rank correlation analysis, γs=0.746, P<0.01).All of the 226 eyes with Hasner valve obstruction were cured.Bony nasolacrimal duct obstruction was 30 eyes, 16 eyes were cured (the cure rate was 53.3%).The cure rate of two parts of the obstruct had significant difference.There were no cases of infection and false passage.
· CONCLUSlON: The treatment of primary lacrimal passage irrigation and probing in neonatal daryocystitisis effective and safe, the optimal timing of treatment is 1 ~9mo.With the growth of age, the cure rate is decreased.
