AIM: To evaluate the results of preservative free sodium hyaluronate and basic fibroblast growth factor(bFGF) eye drops in the treatment of dry eyes after eye operation.·METHODS: One hundred and thirty two patients of dryeyes underwent 149 different eye surgeries. The Schirmer test Ⅰ and tear break up time (BUT) were performed prior to surgery and post operatively after 2 weeks and after 4 weeks when the patients were using Oflaxacine, Tobramycin-dexamethasone eye drops. In addition, preservative free sodium hyaluronate and bFGF eye drops were given post operatively. The antibiotic-cortisone eye drops were stopped after the requirted period depending on the type of eye surgery done, and preservative free sodium hyaluronate and bFGF eye drops were stopped after 4 weeks.Then, after 5 weeks Schirmer test Ⅰ and BUT were done.·RESULTS: The Schirmer test Ⅰ and BUT results prior to surgery and after eye surgery showed a statistically significant improvement of the dry eye condition.·CONCLUSION: Usage of preservative free sodium hysluronate and bFGF eye drops help definitely in the management of dry eye after ophthalmic surgery.

OBJECTIVETo study the relationship of inspiratory capacity (IC) with body mass index (BMI), fat free mass index (FFMI), and fat mass index (FMI) in adults with normal lung function.

METHODSBased on a survey on the Chinese physiological constants conducted in Heilongjiang during 2008, we obtained the data of 2,050 adults (921 men and 1,129 women aged 19-81 years) with normal lung function and grouped them according to the standard of classification of body weight recommended by Working Group on Obesity of China. Statistical analysis was performed using Pearson correlation analysis, one-way analysis of variance,and multi-factor regression analysis.

RESULTSAfter the influences of age and gender were adjusted, IC was positively correlated with BMI, FFMI, and FMI in adults aged 19-81 years (all P= 0.000) (the correlation coefficients were 0.320, 0.303, and 0.204, respectively). The means of IC, FFMI, and FMI in obesity group were significantly higher than those in overweight group normal weight group, and underweight group, were significantly higher in overweight group than in normal weight group and underweight group, were significantly higher in normal weight group than in underweight group (all P = 0.000). Multiple stepwise regression analysis showed that factors including age, gender, height, FFMI, and FMI influenced IC, and while height, FFMI, and FMI were positively correlated with IC, gender and age were negatively correlated with IC.

CONCLUSIONSBMI, FFMI, and FMI are positively correlated with IC in adults with normal lung function. The elevation of IC derived from BMI may attribute to FFMI and FMI, and FFMI has a higher influence on IC than FMI does.

ObjectiveTo measure the iodine content of normal thyroid and the sternocleidomastoid muscle with gemstone spectral imaging (GSI),in order to offer diagnostic reference for iodine excess or iodine deficiency disorders.MethodsA total of 226 cases of patients with suspected neck or cervical disease underwent GSI of the neck,the thyroid and the sternocleidomastoid muscle.One hundred and nineteen cases were male and 107 female,aged 18 to 77 years,average age(46 ± 17) years.Data were transmitted to AW 4.4 workstation and processed using GSI Viewer software to obtain the best contrast-to-noise ratio(CNR) of thyroid to sternocleidomastoid muscle and corresponding singe-energy images.Iodine content of left and right thyroid lobes and both sides of sternocleidomastoid muscle as well as iodine content ratio of thyroid to sternocleidomastoid muscle were calculated in the iodine-based images.ResultsTotal iodine content of the left and the right lobes of the thyroid was (1.5233 ±0.4318)mg/cm3,of the left lobe was (1.5230 ± 0.4271 )mg/cm3,of the right lobe was (1.5236 ± 0.4365 )mg/cm3,there was no significant difference statistically between the two(t =0.0084,P ＞ 0.05).The iodine content of the male was (1.6395 ± 0.4105)mg/cm3,and of the female was (1.4238 ± 0.3832)mg/cm3,there was statistically a significant difference between the two(t =3.4743,P ＜ 0.01 ).Iodine content ratio of thyroid to sternocleidomastoid muscle was 96.6271 ± 33.2442,the ratio in male was 94.6250 ± 37.3621 and in female was 98.0000 ± 29.0737,there was no statistical difference between the two(t =0.3817,P ＞ 0.05).The iodine content of thyroid decreased gradually with age,the difference between groups was statistically significant(F =9.66,P ＜ 0.01 ).The iodine content in ＜ 40 age group[(1.7256 ± 0.4631)mg/cm3] was higher than that in 40 - 60 age group[(1.4517 ±0.3643)mg/cm3] and ＞ 60 age group [(1.4368 ± 0.3465)mg/cm3; q =5.6195,5.4158,all P ＜ 0.01).Conclusions It is easy to calculate thyroid iodine content with gemstone spectral imaging,which can reflect the iodine level of our body,and is helpful for the diagnosis of iodine excess or iodine deficiency disorders.

OBJECTIVE: To explore the effect of selective lumbosacral posterior rhizotomy(SPR) on lower limb spasticity and gross motor function in patients with cerebral palsy. METHODS: From January 2018 to October 2018, 47 patients with cerebral palsy were treated with rehabilitation alone and SPR combined with rehabilitation. According to whether SPR was performed, the patients were divided into group A and group B. Group A was treated with rehabilitation combined with SPR at lumbosacral level, and group B was treated with rehabilitation alone. There were 23 cases in group A, including 15 males and 8 females, with an average age of (7.30±3.25) years old; 24 cases in group B, 13 males and 11 females, with an average age of (7.00±3.09) years old. Forty-seven patients were assessed with modified Ashworth(MAS) and Gross Motor Function Scale(GMFM-88 items) before and after treatment. The changes of MAS and GMFM-88 scores before and after treatment were compared to evaluate the degree of spasm and the improvement of gross motor function in the two groups. RESULTS: All 47 patients were followed up. At 6 months after treatment, the MAS classification of the two groups was significantly improved(<0.05), and the improvement of group A was more obvious than that of group B(<0.05). Six months after treatment, the D, E and total scores of GMFM-88 between two groups were significantly improved compared with those before operation(<0.05). The improvement of D and total scores in group A was more obvious than that in group B. There was no significant difference in the improvement of area E between two groups. CONCLUSIONS Selective posterior rhizotomy combined with rehabilitation can significantly improve the spastic state and gross motor function of lower limbs in children with cerebral palsy, and can effectively promote the reconstruction and recovery of motor function of lower limbs in children with cerebral palsy.

In China there are 1,923,842 Korean Chinese, who live mostly (92.27%) in the country's three northeast provinces. In spite of this sizeable number, no spirometric data are available at present on them. The present study investigated normal spirometric reference values for the Korean Chinese children and adolescents. Spirometry was performed in 443 healthy Korean Chinese children and adolescents aged 8-18 yr with measurements of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF) and maximum mid-expiratory flow (MMEF). Reference equations for FEV1, FVC, PEF and MMEF were derived by using multiple regression analysis. All of the measured spirometric parameters correlated positively with height and age significantly (P < 0.001). The predicted values of FVC and FEV1 were higher than values obtained by using Caucasian and other Asian equations (P < 0.001). A set of spirometric reference equations has been derived using a relatively large, healthy, non-smoking young Korean Chinese population with a wide range of ages and heights, the results of which differ from those gained from several other reference equations. These reference equations should be used for evaluation of lung function in this population.

OBJECTIVETo investigate the clinicopathological characteristics and prognostic factors in patients with intra-abdomen extragastrointestinal stromal tumors (EGISTs).

METHODSThe data of 47 patients of mesenchymal neoplasms that arose from the abdominal cavity and retroperitoneum, collected from July 1987 to June 2003 in our hospital with complete clinical and pathological data, were investigated retrospectively. EGISTs were diagnosed by reviewing the tumor slides stained with hematoxylin and eosin (H&E). Immunohistochemistry staining were performed on CD117, CD34, smooth muscle actin, Desmin and S-100 proteins. The relations of various clinicopathologic characteristics and outcomes were examined.

RESULTSAmong the 47 cases, 30 tumors were confirmed to be EGISTs. Twelve cases arose from the mesentery, six from small omentum, eight from retroperitoneum and four from the abdominal cavity. The size of tumors ranged from 4 to 30 cm (median 12.5 cm) in diameter and the tumor cell components mainly included spindle cells (23 cases), epithelioid cells (4 cases), and mixed cells (3 cases). The follow-up rate was 90% and the median follow up time was 44 months. The patient survival rates at 1, 5 and 10 years were 79.7%, 59.5% and 45.4% respectively. Univariate analysis showed that tumor size >10 cm, tumor necrosis, mitoses > or =5/50HPF, obvious nuclear atypia, moderate and poor differentiated tumor cells were predictors of poor prognosis.

CONCLUSIONSEGISTs have specific clinical behaviors. The parameters used for predicting GISTs prognosis are not completely applicable for EGISTs. Tumor necrosis, obvious nuclear atypia and mitoses > or =5/50HPF help to predict aggressive behaviors in EGISTs.

OBJECTIVETo identify the clinical pathological characteristics and prognostic factors in patients with gastrointestinal stromal tumors of the stomach.

METHODSThe data of 98 patients of gastric stromal tumors, leiomyomas, leiomyosarcomas, leiomyoblastomas, schwannomas and neurofibromas, collected from Mar. 1983 to Dec. 2001 in our hospital with complete clinical and pathological data, were investigated retrospectively. Gastric stromal tumors were diagnosed by reviewing the tumor slides stained with hematoxylin and eosin (H&E). Two histomorphologically representative areas of each tumor slides were identified and arrayed on a tissue microarray. Immunohistochemistry staining were performed using antibodies to c-kit (CD117), CD34, smooth muscle actin (SMA), Desmin and S-100 proteins. The relations of various clinicopathologic characteristics and outcomes were tested by univariate analysis and multivariate analysis.

RESULTSNinety-one patients were clearly identified as gastric stromal tumors from the 98 patients, who were diagnosed as gastric stromal tumor, leiomyoma, leiomyosarcoma, leiomyoblastoma schwannoma and neurofibroma (92.9%). The follow-up rate was 91% and the median follow up time was 54 months. The patient survival rates at 1, 5 and 10 years were 88.8%, 79.6% and 63.7% respectively. Univariate analysis showed that tumor size, mitotic count, tumor necrosis, nuclear pleomorphism, cell type, cell density, surgical procedure, mucosal invasion, age and lable index of Ki-67 were associated with prognosis (P<0.05). Multivariate analysis showed that tumor size, mitotic count, mucosal invasion and tumor necrosis were predictors of prognosis (P<0.05).

CONCLUSIONTumor size of >10 cm, mitotic count of >10 mitoses per 50 high power fields, necrosis and mucosal invasion are often associated with an aggressive clinical course in gastric stromal tumors.

OBJECTIVETo investigate the effects of different-intensity sinusoidal electromagnetic fields (SEMFs) on bone mineral density (BMD) and histomorphometry in SD rats.

METHODSThirty female SD rats were randomly divided into three groups: group A (a control group), group B (0.1 mT group) and group C (0.6 mT group). The rats in group B and C were exposed to 50 Hz SEMFs 3 hours each day. However,the magnetic intensity was different between group B and group C:0.1 mT for group B and 0.6 mT for group C. After 8 weeks, all the animals were killed. Changes of BMD and histomorphometric properties were observed.

RESULTSCompared with group A, the BMD of whole body, femur and vertebrae of rats in group B increased significantly; the area percentage, number and width of bone trabeculae in vertebrae and femur of rats in group B were larger than those of group A; but the resolution of bone trabeculae of rats in group B was lower than that of group A. The trabecular number in group C rats were significantly decreased, compared with that in group A rats. The outcome of double fluorescence labeling in group B was found to be significantly different with that in group A. But the difference between rats in group A and C was not significant.

CONCLUSIONThis study demonstrates that 50 Hz 0.1 mT SEMFs can increase BMD, improve bone tissue microstructure and, promote bone formation.

OBJECTIVETo examine the effect of body fat mass and fat distribution on pulmonary ventilatory function among the adult females.

METHODSBased on the multistage cluster sampling principal, we selected 935 healthy adult females with ages of 19-81 years old in Heilongjiang province to conduct the study. Every 10-years old as a age group. Firstly obtain the basic situation through the questionnaire survey, and then measure the height, body weight, waistline, hip circumference, body composition and lung function. FVC, FEV1, PEF, FEF25%, FEF 50%, FEF 75% and MMEF were determined. This study also examined the relationships between percentage body fat (PBF), waist-hip ratio (WHR) and FVC, FEV1, PEF, FEF25%, FEF 50%, FEF 75%, MMEF.

RESULTSPBF of subjects with ages of 19 - 29 years old and over 60 years old were (16.89 ± 5.34)% and (24.39 ± 6.83)%, WHR were 0.77 ± 0.05 and 0.88 ± 0.06, respectively. PBF and WHR tended to increase with age (F = 50.11, P value < 0.01). PBF obesity rates of subjects with ages of 19 - 29 years old and over 60 years old were 3.23% (7/217) and 43.75% (28/64), WHR obesity rates were 19.35% (42/217) and 85.94% (55/64) respectively. PBF obesity rate and WHR obesity rate tended to increase with age (χ(2) = 161.66, P value < 0.01; χ(2) = 159.61, P value < 0.01). PBF obesity groups compared with the normal groups, the former pulmonary ventilation function reduced significantly, of which FEF 50%, FEF 75% and MMEF decreased 2.61%, 19.44%, 10.28%, respectively. WHR obesity groups compared with the normal groups, the former pulmonary ventilation function reduced significantly, of which FEF 50%, FEF 75% and MMEF decreased 7.61%, 23.15%, 12.04%. After adjustment of age, height and body mass index (BMI), PBF was negatively correlated with FVC, FEV1, PEF and FEF25% (r values were -0.14, -0.14, -0.07, -0.07, respectively, all P value s < 0.05); WHR was negatively correlated with FEV1 (r value was -0.07, P value < 0.05) after adjustment of age, height and BMI.

CONCLUSIONPBF augmentation and abdominal obesity among adult females may be the risk factors of pulmonary function impairment.
