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.

UNLABELLEDOBJECTIVE To study the clinicopathologic features, radiologic findings, treatment modalities and prognosis of dysembryoplastic neuroepithelial tumor (DNT).

METHODSThe clinical features, histopathologic findings, immunohistochemistry and electron microscopy of 18 cases of DNT were analyzed. Results Among the 18 cases studied, 14 were males and 4 females. The age of these patients ranged from 3 to 46 (mean age = 22. 8 years). Partial seizure was the main presenting symptom in all patients. The history of epilepsy could be as long as 17 years. On magnetic resonance imaging (MRI) study, the tumor was hypodense on T1 and hyperdense on T2. There was neither edema nor mass effect. All but 2 cases were supratentorial and intracortical in location. Ten cases were treated by complete surgical excision and the remaining 8 tumors were partially excised. In the 14 patients with follow-up data available, 13 survived for 1.4 to 11 years after the operation (with more than 10 years survival observed in 2 patients). The average survival period was 5.5 years. None of the cases showed tumor recurrence after operation. Histologically, all tumors demonstrated a multinodular architecture and were intracortical in location, sometimes with extension into the white matter. The characteristic "glioneuronal constituent" was an essential feature for making the diagnosis of DNT. The tumor was formed by an admixture of oligodendrocyte-like cells, mature neurons and astrocytes, with obvious microcystic changes. These neurons were often dispersed singly in the mucoid matrix. In most cases, the foci of cortical dysplasia were found in adjacent areas. Immunohistochemical study demonstrated positivity for synaptophysin, neurofilament and S-100 protein in the neurons and some oligodendrocyte-like cells. The staining of glial fibrillary acidic protein in the oligodendrocyte-like cells was negative. Electron microscopy showed early neuronal, astrocytic and oligodendroglial differentiation of the oligodendrocyte-like cells.

CONCLUSIONSDNT is a benign tumor (corresponding to WHO grade I) that can be cured by surgical excision, despite sometimes incomplete tumor removal. A correct diagnosis of this entity requires thorough understanding of the clinical, radiologic, histologic and immunohistochemical features.

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.

The aim of this study is to develop backpropagation neural networks (BPNN) for better prediction of ventilatory function in children and adolescents. Nine hundred and ninety-nine healthy children and adolescents (500 males and 499 females) aged 10-18 years, all of the Han Nationality, were selected from Inner Mongolia Autonomous Region, and their heights, weights, and ventilatory functions were measured respectively by means of physical examination and spirometric test. Using the approaches of BPNN and stepwise multiple regression, the prediction models and equations for forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), forced expiratory flow at 25% of forced vital capacity (FEF25%), forced expiratory flow at 50% of forced vital capacity (FEF50%), maximal mid-expiratory flow (MMEF) and forced expiratory flow at 75% of forced vital capacity (FEF75%) were established. Through analyzing mean squared difference (MSD) and correlation coefficient (R) of the ventilatory function indexes, the present study compared the results of BPNN, linear regression equation based on this work (LR's equation), prediction equations based on the studies of Ip et al. (Ip's equation) and Zapletal et al. (Zapletal's equation). The results showed, regardless of sex, the BPNN prediction models appeared to have smaller MSD and higher R values, compared with those from the other prediction equations; and the LR's equation also had smaller MSD and higher R values compared with those from Ip's and Zapletal's equations. The coefficients of variance (CV) for FEF50%, MMEF and FEF75% were higher than those of the other ventilatory function parameters, and their increasing percentages of R values (ΔR, relative to R values by LR's equation) derived by BPNN were correspondingly higher than those of the other indexes. In sum, BPNN approach for ventilatory function prediction outperforms the traditional regression methods. When CV of a certain ventilatory function parameter is higher, the superiority of BPNN would be more significant compared with traditional regression methods.

The aim of the present study was to evaluate the relation between fat mass (FM), fat free mass (FFM) and ventilatory function in children and adolescents. 1 174 healthy children and adolescents (583 males and 591 females) aged 10-18 years were selected from Heilongjiang Province through random sampling by means of questionnaire and physical examination, and measured for height, weight, waist to hip ratio (WHR), FM, FFM and ventilatory function. The data were analyzed by means of independent-samples t test, Pearson correlation analysis and multi-factors regression analysis. Regardless of sex, an independent positive correlation was found (P<0.001) between age and FFM index (FFMI). FM index (FMI) correlated negatively with age in males (P<0.001), but positively with age in females (P<0.001). Regardless of sex, FFMI correlated positively with forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), forced expiratory flow at 25% of forced vital capacity (FEF25%), FEF50%, and maximal mid-expiratory flow (MMEF) (P<0.05), while negatively with FEV1/FVC (P<0.01). FFMI was correlated positively with FEF75% in males (P<0.05), but not correlated in females. In males, FMI correlated negatively with FEV1, FEV1/FVC, PEF, FEF25%, FEF50%, FEF75% and MMEF (P<0.05), but not correlated with FVC. No correlation was found between the ventilatory function indices and FMI in females. Except FEV1/FVC and FEF75% in males, the effect of FFMI in predicting ventilatory function was higher than FMI regardless of sex. Moreover, the predicting effect of FFMI was higher in males than that in females. Growth spurt of lung function occurred in the ages of 12-15 years in males, while in the ages of 12, 13 and 18 years in females. During the period of growth spurt of lung function, regardless of sex, the effect of FFMI in predicting the lung function was higher than that of age. In conclusion, regardless of sex, FFMI correlates positively with ventilatory function, as a reflection of muscle mass. The effect of FFM in predicting ventilatory function is higher in males than that in females. FM correlates negatively with ventilatory function in males, but not in females. The rapid growth of height and FFM are possibly the main reasons for growth spurt of lung function.
