Abstract
Objective: To evaluate the efficacy of 0.05% cyclosporine A eye drops combined with vitamin A palmitate eye gel in the treatment of dry eye associated with meibomian gland dysfunction (MGD). Methods: A single-center, prospective, randomized, parallel controlled trial design was used to include patients diagnosed with MGD-associated dry eye. The patients were randomly divided into three groups and administered with medications binocularly for 12 weeks. The CsA+VA group was given 0.05% cyclosporine A eye drops twice a day and vitamin A palmitate eye gel three times a day. The CsA+HA group was given 0.05% cyclosporine A eye drops twice a day and 0.1% sodium hyaluronate eye drops three times a day. The HA group was given 0.1% sodium hyaluronate eye drops 3 times a day. The OSDI score, tear meniscus height, fluorescein tear break-up time, Schirmer Ⅰ test (without anesthesia), tear film lipid layer thickness, meibomian gland morphology and function examination, and corneal fluorescein sodium staining score were evaluated at baseline, 4, 8, and 12 weeks after the initiation of the treatment, respectively. Results: A total of 120 patients with MGD-related dry eye met the enrollment criteria, but 10 patients were lost to follow-up; 110 patients were finally included for observation, including 36 patients in the CsA+VA group, 38 in the CsA+HA group and 36 in the HA group. The OSDI score, tear meniscus height, fluorescein tear break-up time and meibomian gland secretion of the 3 groups were significantly improved. At the 12th week of the treatment, the differences of the CsA+VA group [25.45±15.11, (0.30±0.13) mm, (3.72±1.40) s, (5.03±2.52) points] and the CsA+HA group [26.98±16.89, (0.27±0.10) mm, (4.34±1.76) s, (5.11±2.39) points] from the HA group [24.57±11.26, (0.24±0.06) mm, (3.18±1.11) s, (9.11±3.34) points] were statistically significant (P<0.05). Compared with the CsA+HA group [(68.39±26.66) nm], the tear film lipid layer thickness in the CsA+VA group [(72.61±23.65) nm] was significantly increased (P<0.05). In the CsA+VA group, the meibomian gland secretion characters and discharge capacity among patients with severe abnormalities [(6.28±2.59) and (5.89±2.77) points at the 12th week of treatment], moderate abnormalities [(4.27±2.02) and (4.64±2.02) points at the 12th week of treatment] and mild abnormalities [(2.80±0.84) and (2.60±0.55) points at the 12th week of treatment] were significantly different (P<0.05). Conclusion: 0.05% cyclosporine A combined with vitamin A palmitate can significantly improve the symptoms and signs of patients with MGD-related dry eye, especially the tear film lipid layer thickness and the meibomian gland secretion characters and discharge capacity in severe cases.

Abstract
This research aimed to assess gray matter (GM), white matter (WM), lesions of multiple sclerosis (MS) and the therapeutic effect using diffusion kurtosis imaging (DKI). From January 2018 to October 2019, 78 subjects (48 of MS and 30 of health) perform routine MR scan and DKI of cervical spinal cord. The MS patients were divided into 2 groups according to the presence or absence of T2 hyperintensity. DKI-metrics were measured in the lesions, normal-appearing GM and WM. Significant differences were detected in DKI metrics between MS and healthy (P < .05) and between patients with cervical spinal cord T2-hyperintense and without T2-hyperintense (P < .001). Compared to healthy, GM-mean kurtosis (MK), GM-radial kurtosis, and WM-fractional anisotropy, WM-axial diffusion were statistically reduced in patients without T2-hyperintense (P < .05). Significant differences were observed in DKI metrics between patients with T2-hyperintense after therapy (P < .05), as well as GM-MK and WM-fractional anisotropy, WM-axial diffusion in patients without T2-hyperintense (P < .05); Expanded Disability Status Scale was correlated with MK values, as well as Expanded Disability Status Scale scores and MK values after therapy. Our results indicate that DKI-metrics can detect and quantitatively evaluate the changes in cervical spinal cord micropathological structure.

Abstract
Objective: To compare the protective effects of vitamin A eye gel combined with 3M transparent tape and erythromycin eye ointment combined with 3M transparent tape on the eye surface during head and neck surgery under general anesthesia. Methods: From June to December 2021, a total of 120 patients undergoing elective head and neck surgery under general anesthesia in Beijing Tongren Hospital, Capital Medical University were enrolled. Each participant was randomly received vitamin A eye gel (vitamin A eye, n=60) or erythromycin eye ointment (erythromycin eye, n=60), followed by 3M transparent tape on one eye, and taping 3M transparent tape alone for the other eye. The hand-held slit lamp examination was performed 3 times at before induction of anesthesia, after resuscitation in the post anesthesia care unit (PACU) and 1 day after surgery. The primary outcome was corneal fluorescein sodium staining (CFS) score. Secondary outcomes included symptom assessment in dry eye (SANDE) questionnaire score, basic tear secretion test (Schirmer I test, SIt), break-up time (BUT) and incidence of adverse reactions. Results: Comparison within groups showed that CFS scores were significantly higher in vitamin A eyes and erythromycin eyes at PACU than before induction (P<0.05). Comparison between groups showed that CFS score at PACU in erythromycin eyes (0.62±0.16) was significantly higher than that in vitamin A eyes (0.13±0.01, P=0.007). Compared with before induction, SIt at PACU was significantly increased in the erythromycin eyes [(16.0±1.3) vs (11.4±4.9) mm, P=0.017],and was significantly decreased in vitamin A eyes [(10.2±3.6) vs (12.4±5.5) mm, P=0.046]. The BUT in PACU of erythromycin eyes, vitamin A eyes were (6.4±2.5) s, (6.8±2.1) s, respectively,and were significantly decreased compared with before induction (P<0.05). Comparison between groups showed that there was no significant difference in BUT and SANDE in PACU between two groups (P>0.05). For erythromycin eyes, discomfort symptoms in PACU included viscosity (66.7%, 40/60), conjunctival congestion (21.7%, 13/60), tingling (8.3%, 5/60), blurred vision (58.3%, 35/60). The incidence of these complications in vitamin A eye was 30.0% (18/60), 5.0% (3/60), 0 and 6.7% (4/60), respectively, and all the incidences were significantly higher than those of vitamin A eyes (all P<0.05). Conclusion: For patients undergoing head and neck surgery under general anesthesia, the combination of vitamin A ocular gel and 3M transparent tape is more effective in prevent postoperative ocular surface injury than the combination of erythromycin ointment and 3M transparent tape.

Abstract
Blepharokeratoconjunctivitis, (BKC) is a common ocular surface chronic inflammatory disease in children. It can cause eye irritation or even visual impairment. At present, the etiology of BKC in children is not clear and relevant studies are in the initial stage, consequently, there has not been an authoritative applicable expert consensus in China. Compared with adults, the clinical manifestations of pediatric patients are often atypical, coupled with the lack of understanding, so inadequate diagnosis and treatment are still exist in pediatric BKC. This article reviews the etiology, diagnosis and treatment status, clinical characteristics, standardized diagnosis and treatment of pediatric BKC, in order to arouse the attention of ophthalmologists.

Abstract
Laser-aided interferometers are employed as the common diagnostics for electron density measurements. On the EAST (Experimental Advanced Superconducting Tokamak), we have four main electron density diagnostics-the far-infrared hydrogen cyanide interferometer, polarimeter/interferometer, carbon dioxide (CO2) dispersion interferometer, and solid-state source interferometer. For interferometers, the phase difference brought by the change in electron density can be acquired via mixers. A real-time data acquisition (DAQ) system is needed to calculate the highly precise density values. In this paper, a field-programmable gate array is employed to implement the system with fast Fourier transform-based demodulation technology. A highly precise analog/digital converter is employed for readout and digitization of the waveform including multiple frequency signals from high-performance Schottky mixers. The system has been simulated, and the results show that it can meet the requirements of the accuracy of interferometers on the EAST. Furthermore, the framework of the DAQ system also offers a reference of the data processing method to the future laser-aided interferometers.

Abstract
A 52-year-old male presented to Beijing Tongren Hospital with a 5-year history of bilateral dry eyes. He had been diagnosed with Steven-Johnson syndrome due to allergy to cold medication. On examination, the Schirmer I test value was 0 mm, the tear break-up time was 0 s, and corneal fluorescein staining showed corneal epithelial erosion with partial fusion in both eyes. The clinical diagnosis was dry eyes (severe) and Steven-Johnson syndrome. No significant effect was observed after use of artificial tears and anti-inflammatory eye drops and tear punctal embolization. Then an insular infraorbital neurovascular pedicle labial salivary gland transplantation was performed in the right eye. During the 1-year postoperative follow-up, the symptoms and signs were significantly improved in the operated eye, and the surgical results were satisfactory. (Chin J Ophthalmol, 2021, 57: 946-948).

Abstract
Objective: To explore the prevalence and influencing factors of allergic conjunctivitis in Baotou area at different times. Methods: A cross-sectional study was conducted in January 2021, 111 patients with allergic conjunctivitis who were admitted to the Department of Ophthalmology, the Second Affiliated Hospital of Baotou Medical College, Inner Mongolia University of Science and Technology in 2020 were selected as the research subjects. The basic information, allergic conditions, living habits and other information of the patients were obtained by self-made questionnaire. The pollen concentration and allergy related indicators(allergic duration and frequency, eye itching score, eye burn score, eye foreign body sensation score, tears score and the total scores) of 2019 and 2020 were analyzed by paired sample t-test. The pollen concentration of 2019 and 2020 were analyzed by Wilcoxon signed rank test. The allergy related indicators of different genders were analyzed by independent sample t-test. The allergy related indicators of different ages were analyzed by one-way analysis of variance. The relationship between the length of wearing masks and the allergy related indicators were analyzed by Spearman correlation analysis. Results: Among the 111 patients with allergic conjunctivitis, 54 were males and 57 were females, ranging in age from 8 to 69 years old, with a median age of 35 years old and an average age of (36.77±13.18) years old. The average pollen concentration in Baotou in 2019 was (125.35±222.64) grains/1 000 square millimeter, and the average pollen concentration in Baotou in 2020 was (107.38±137.29) grains/1 000 square millimeter. There was no significant difference in pollen concentration between the two years(Z=-0.178, P=0.859). The severity of allergic indicators in all patients in 2020 is significantly lower than in 2019(t values were 4.701,3.587,2.582,3.661,4.444,2.784,2.555,3.886,respectively, with P<0.05). The severity of allergic indicators in male patients is lower than that of female patients (t values were -1.558, -1.257, -3.41, -3.085, -2.335, -2.897, -2.652, -4.124, respectively). The prevalence of allergic conjunctivitis dose not vary significant with age (P values were 0.504, 0.095, 0.499, 0.265, 0.284, 0.655, 0.421, 0.976, respectively). In 2020, the average time that patients wear masks is (6.55±3.28) h/d, and there is a correlation with the difference in allergy duration (r=0.191, P=0.045). Conclusion: The severity of allergic conjunctivitis in Baotou in 2020 was significantly improved compared with that in 2019, which may be related to masks wearing.

Abstract
Objective: To evaluate the clinical effects of orthokeratology lens on children with myopic anisometropia. Methods: Retrospective case series study. The data of 226 myopic anisometropia children, (10.83±1.56)years old, including 95 males and 131 females, fitted with orthokeratology(OK) lens in Beijing Tongren Hospital from June 2017 to June 2019 were collected. According to the lens wearing condition and baseline anisometropia, they were divided into four groups: group A1 with an average age of (10.68±1.66) years (bilateral OK lens wearing with low anisometropia, 1.0 D≤SE difference<2.5 D, 50 males and 61 females), group A2 with an average age of (11.24±1.38) years (bilateral OK lens wearing with moderate and high anisometropia, SE difference≥2.5 D, 10 males and 23 females), group B1 with an average age of (10.79±1.51) years (unilateral OK lens wearing with low anisometropia, 1.0 D≤SE difference<2.5 D, 17 males and 21 females) and group B2 with an average age of (10.97±1.60) years (unilateral OK lens wearing with moderate and high anisometropia, SE difference≥2.5 D, 18 males and 26 females). After wearing OK lens for one year, the changes of axial length(AL) and AL difference were observed and statistically analyzed. Results: (1) AL changes: after wearing OK-lens for one year, AL of each eye increased. In group A1, the AL of the more myopic eyes and the less myopic eyes increased by (0.20±0.21) mm and (0.24±0.22) mm respectively, and the difference was statistically significant (t=-3.208, P=0.002); in group A2, the AL growth of the more myopic eyes and the less myopic eyes were (0.04±0.11) mm and (0.17±0.14) mm, and the difference was statistically significant (t=-5.545, P<0.001). In group B1, the AL elongation of the more myopic eyes and the less myopic eyes were (0.14±0.21) mm and (0.39±0.23) mm, and in group B2, the AL growth of the more myopic eyes and the less myopic eyes were (0.11±0.14) mm and (0.54±0.24) mm, with statistically significant differences(t=-6.533, -11.643; all P<0.001). There was a linear correlation between AL elongation and age of the more myopic eyes and the less myopic eyes in group A1(corrected R2=0.208, 0.237) and group A2 (corrected R2=0.169, 0.360). There was no linear correlation of the more myopic eyes and the less myopic eyes between AL change and age or baseline myopia in group B1 (F=0.514, 1.205;P=0.602, 0.312) and group B2 (F=0.841, 0.056; P=0.439, 0.946). (2)Change of AL difference: after wearing OK lens for one year, the changes of AL difference in groupA1, A2, B1 and B2 were (-0.04±0.14) mm,(-0.13±0.13) mm,(-0.26±0.24) mm and (-0.43±0.25) mm, and the decrease of AL difference in moderate and high anisometropia groups were greater than that in low anisometropia groups (t =-3.211, -3.180; P=0.002, 0.002).There was a linear correlation between the reduction of AL difference and baseline anisometropia in group A1, A2 and B2 (corrected R2=0.099, 0.149, 0.230), and there was no linear relationship between the decrease of AL difference and the baseline anisometropia in group B1 (F=0.014, P=0.908). Conclusions: Orthokeratology could effectively control the progression of myopia and to treat anisometropia. The effect of myopia control was better in the older binocular OK lens wearers, and for the patients with greater baseline anisometropia, the treatment effect of anisometropia was better.

Abstract
Objective: To observe the clinical effect of modified conjunctival transplantation and amniotic membrane transplantation combined with use of interferon (IFN) alpha-2b eye drops in the treatment of primary pterygium. Methods: This was a prospective case-control study. Patients with primary pterygium were treated from June 1, 2018 to December 31, 2018 in the Department of Ophthalmology, Beijing Tongren Hospital, and they were divided into two groups (the experimental group and the control group) by the method of randomized block design. Patients in the experimental group received modified conjunctival transplantation and amniotic membrane transplantation combined with use of IFN alpha-2b eye drops, while patients in the control group received pterygium resection combined with conjunctival autograft transplantation. The pterygium type and size were observed before operation, while visual acuity, intraocular pressure and anterior segment details were recorded either. The follow-up was done at 1 week, 2 weeks, 1 month, 3 months, 6 months and 12 months after operation. The visual acuity, corneal epithelial defect, and pterygium recurrence were observed. All data in this manuscript are enumeration data, the expected frequency of pterygium type distribution in the two groups was more than 5, and the chi square test was used, fisher's exact test was used to compare the other data between the two groups. Results: Seventy patients (77 eyes) with pterygium were in this study, including 30 males and 40 females, aged from 50-70 years old. There were 35 cases (38 eyes) in the experimental group and 35 cases (39 eyes) in the control group. 12 months after operation there were 54 cases (60 eyes) including 28 cases (30 eyes) in the experimental group and 26 cases (30 eyes) in the control group with complete data. The corneal epithelium defects of 1 eye in each group was repaired within 7-14 days after operation, and the rest eyes were completely repaired within 7 days after operation. There was no significant difference in the distribution of corneal epithelial healing between the two groups (P= 1.00). There was no significant difference between the two groups in the number of eyes distribute with decreased visual acuity (2 eyes in each group), stable visual acuity (15 eyes in the experimental group and 23 eyes in the control group), and improved visual acuity (13 eyes in the experimental group and 5 eyes in the control group) (P=0.053). There was no recurrence in the two groups at 12 months after surgery, and there was no significant difference between the two groups in the number of patients with conjunctival hyperplasia of grades 1, 2 and 3 (P=0.405). Conclusions: Modified conjunctival transplantation and amniotic membrane transplantation combined with use of IFN alpha-2b eye drops got low recurrence rate for primary pterygium and less damage to the healthy conjunctival tissue. This combined treatment strategy provides a new choice for the treatment of pterygium. (Chin J Ophthalmol, 2020, 56: 768-773).

Abstract
This article was published ahead of print on the official website of Chinese Journal of Ophthalmology on March 2, 2020. Prevention and control of novel coronavirus pneumonia is now the top priority, and the protection of the eyes in the fight against the epidemic has also been an issue of great concern. Based on the latest progress made in basic and clinical research and practical experience in epidemic prevention and control, this article delivers objective guidance on whether the eye is a route of transmission of novel coronavirus infection, the precautions that should be taken by ophthalmologists in clinical practice during the epidemic, the novel coronavirus infection in the eyes and its clinical manifestation, and the public health education on eye protection, so as to provide valuable evidence for the scientific prevention and control of the epidemic and developing targeted countermeasures.

Abstract
Meibomian gland dysfunction (MGD), as a chronic,diffuse Meibomian gland disease,is one of the most common ophthalmological clinical diseases. Symptoms can be mild,such as ocular discomfort, but severe cases resulting in ocular surface damage could affect patients' visual function. Moreover,with the absence of a thorough examination of eyelid status and Meibomian gland prior to ocular surface surgery, it could cause severe postoperative complications. As a usual but easily overlooked disease, MGD and its associated ocular surface diseases have drawn greater attention,on the other hand,some emerging therapies,in addition to the clinically recognized treatments, provided doctors with more effective treatments at their disposal,and plenty of research achievements have been published. This article emphasizes on new physical approaches in the treatments of MGD and its associated ocular surface diseases. (Chin J Ophthalmol, 2019,55:465-468).

Abstract
Few studies evaluate the amount of particulate matter less than 2.5 mm in diameter
(PM2.5) in relation to a change in lung function among adults in a
population. The aim of this study was to assess the association of coal as a domestic
energy source to pulmonary function in an adult population in inner-city areas of
Zunyi city in China where coal use is common. In a cross-sectional study of 104
households, pulmonary function measurements were assessed and compared in 110 coal
users and 121 non-coal users (≥18 years old) who were all nonsmokers. Several
sociodemographic factors were assessed by questionnaire, and ventilatory function
measurements including forced vital capacity (FVC), forced expiratory volume in 1 s
(FEV1), the FEV1/FVC ratio, and peak expiratory flow rate
(PEFR) were compared between the 2 groups. The amount of PM2.5 was also
measured in all residences. There was a significant increase in the relative
concentration of PM2.5 in the indoor kitchens and living rooms of the
coal-exposed group compared to the non-coal-exposed group. In multivariate analysis,
current exposure to coal smoke was associated with a 31.7% decrease in FVC, a 42.0%
decrease in FEV1, a 7.46% decrease in the FEV1/FVC ratio, and a
23.1% decrease in PEFR in adult residents. The slope of lung function decrease for
Chinese adults is approximately a 2-L decrease in FVC, a 3-L decrease in
FEV1, and an 8 L/s decrease in PEFR per count per minute of
PM2.5 exposure. These results demonstrate the harmful effects of indoor
air pollution from coal smoke on the lung function of adult residents and emphasize
the need for public health efforts to decrease exposure to coal smoke.

Abstract
Findings on the effects of weather on health, especially the effects of ambient
temperature on overall morbidity, remain inconsistent. We conducted a time series
study to examine the acute effects of meteorological factors (mainly air temperature)
on daily hospital outpatient admissions for cardiovascular disease (CVD) in Zunyi
City, China, from January 1, 2007 to November 30, 2009. We used the generalized
additive model with penalized splines to analyze hospital outpatient admissions,
climatic parameters, and covariate data. Results show that, in Zunyi, air temperature
was associated with hospital outpatient admission for CVD. When air temperature was
less than 10°C, hospital outpatient admissions for CVD increased 1.07-fold with each
increase of 1°C, and when air temperature was more than 10°C, an increase in air
temperature by 1°C was associated with a 0.99-fold decrease in hospital outpatient
admissions for CVD over the previous year. Our analyses provided statistically
significant evidence that in China meteorological factors have adverse effects on the
health of the general population. Further research with consistent methodology is
needed to clarify the magnitude of these effects and to show which populations and
individuals are vulnerable.

Abstract
Financial access to HIV care and treatment can be difficult for many people in China, where the government provides free antiretroviral drugs but does not cover the cost of other medically necessary components, such as lab tests and drugs for opportunistic infections. This article estimates out-of-pocket costs for treatment and care that a person living with HIV/AIDS in China might face over the course of one year. Data comes from two treatment projects run by Médecins Sans Frontières in Nanning, Guangxi Province and Xiangfan, Hubei Province. Based on the national treatment guidelines, we estimated costs for seven different patient profiles ranging from WHO Clinical Stages I through IV. We found that patients face significant financial barriers to even qualify for the free ARV program. For those who do, HIV care and treatment can be a catastrophic health expenditure, with cumulative patient contributions ranging from approximately US$200-3939/year in Nanning and US$13-1179/year in Xiangfan, depending on the patient's clinical stage of HIV infection. In Nanning, these expenses translate as up to 340% of an urban resident's annual income or 1200% for rural residents; in Xiangfan, expenses rise to 116% of annual income for city dwellers and 295% in rural areas. While providing ARV drugs free of charge is an important step, the costs of other components of care constitute important financial barriers that may exclude patients from accessing appropriate care. Such barriers can also lead to undesirable outcomes in the future, such as impoverishment of AIDS-affected households, higher ARV drug-resistance rates and greater need for complex, expensive second-line antiretroviral drugs.

Abstract
PURPOSE To determine the prevalence of trachoma in the adult Chinese population. METHODS The Beijing Eye Study as a population-based, cross-sectional cohort study included 4439 subjects out of 5324 subjects invited to participate with an age of 40+ years. Trachomatous abnormalities were assessed by slit lamp examination. Examination data were available for 4411 (99.4%) subjects. RESULTS Trachomatous abnormalities were present in 850 eyes (mean+/-SE: 9.64+/-3.14%) or 422 subjects (9.57+/-0.44%), differentiated into follicular trachomatous inflammation (stage 1) (0.92+/-0.11%), intensive trachomatous inflammation (stage 2) (1.01+/-0.11%), trachomatous scarring (stage 3) (7.61+/-0.29%), and trachomatous trichiasis (stage 4) (0.47+/-0.08%). Trachomatous scarring was significantly associated with higher age (P<0.001), low level of education (P<0.001), rural versusurban region (P=0.04), and low visual acuity (P<0.001). CONCLUSION Active trachoma is present in about 2 out of 100 Chinese adults, and trachomatous scarring is present in about in about 8 out of 100 Chinese adults in Northern China with age, socioeconomic background, and rural region as main risk factors.

Abstract
PURPOSE To determine whether the superantigen Staphylococcal enterotoxin B (SEB) combined with interleukin-1 receptor antagonist (IL-1ra) prolong allograft survival better than individual agents in high-risk corneal transplantation in a rat model. METHODS Fisher 344 donor corneas were transplanted into Lewis recipients. High-risk transplantation meant that the transplants were sutured into the recipient beds with corneal neovascularization induced by placing three interrupted sutures in the host cornea. All of the recipients were divided in blinded fashion into four groups. Group I was injected with saline buffer. Group II was injected intraperitoneally with 0.2 mL SEB (75 microg/kg) at 4-day intervals on three occasions before transplantation. Group III was injected with 0.1 mL IL-1ra (1 mg/mL) subconjunctivally from the first day after transplantation for 2 weeks. Group IV received both SEB and IL-1ra. All transplants were evaluated for signs of rejection for 4 weeks after surgery. Ten days after transplantation, two recipients in each group were sacrificed for histopathological and immunological evaluation. RESULTS The mean survival time of the allografts in the control group was 5.89 +/- 0.79 days; in SEB group, 10.70 +/- 2.52 days; in IL-1ra group, 8.25 +/- 0.71 days; in the SEB and IL-1ra group, 17.36 +/- 2.39 days. CD4+ and CD8+ lymphocyte infiltration into the allografts and the percentage of the lymphocytes in the spleen and mandibular lymphatic nodes was significantly decreased among the treated groups with dampened lymphocyte reactivity. The SEB plus IL-1ra combination group showed the strongest inhibition. CONCLUSION SEB and IL-1ra are most effective in combination to treat high-risk corneal transplants.

Abstract
Redisplacement of unstable forearm fractures in plaster is common and may be the result of a number of factors. Little attention has been paid to the influence of immobilisation with the elbow extended versus flexed. We prospectively treated 111 consecutive children from two centres with closed forearm fractures by closed reduction and casting with the elbow either extended (60) in China or flexed (51) in Israel. We compared the outcome of the two groups. There was no statistically significant difference in the distribution of the age of the patients, the site of fracture or the amount of angulation and displacement between the groups. During the first two weeks after reduction, redisplacement occurred in no child immobilised with the elbow extended and nine of 51 children (17.6%) immobilised with the elbow flexed. Immobilisation of unstable forearm fractures with the elbow extended appears to be a safe and effective method of maintaining reduction.

Abstract
AIMS To explore the role of staphylococcal enterotoxin B (SEB) in treating high risk corneal keratoplasty in rats. METHODS Rat corneal high risk transplantation rejection models were set up using Fisher 344 and Lewis rats. The experimental rats were injected intraperitoneally with 0.2 ml SEB at different concentrations before keratoplasty. The rejection indexes of the allograft were recorded and the lymphocyte infiltration in the allograft and the percentage of the lymphocyte subpopulation in the lymphatic organs were also examined. Lymphocyte proliferation ability and the concentration of IL-2 and IL-10 in the serum were also evaluated. RESULTS Compared with the control group, SEB prolonged the survival time of the allograft significantly from 7 to 12 days. It could also reduce CD4(+) and CD8(+) lymphocyte infiltration in the allograft and minimise the percentage of CD4(+) and CD8(+) lymphocytes in the lymphatic organs. The lymphocyte proliferation ability was also weakened. However, the percentage of CD4(+) NK T lymphocytes in the lymphatic organs was raised. The serum concentration of IL-10 was higher but IL-2 was lower in the SEB treated groups. CONCLUSIONS SEB prolonged the survival time of the allograft in high risk rat corneal allo-transplantation, which may be caused by T cell deletion and acquisition of non-specific tolerance.

Abstract
Mobilities of 16 anions of rare-earth-EDTA 1:1 chelate (RE-EDTAs) were isotachophoretically measured by using two leading electrolytes (pH 3.6 and 6.0) in order to assess their separation behavior. The leading electrolyte was 20 mM hydrochloric acid. The pH of the solution was adjusted to 3.6 by adding beta-alanine and to 6.0 by adding histidine. The obtained mobilities were very close to each other in the range 20.1x10(-5)-21.9x10(-5) cm2 V(-1) s(-1) with the minimum mobilities for Pr-EDTA and Nd-EDTA for pH 3.6 and 6.0, respectively, and pH dependence was hardly observed. On the basis of the above knowledge. minor rare-earth elements in a standard iron ore sample were determined as RE-EDTAs by bidirectional isotachophoresis-particle-induced X-ray emission (PIXE), where the Fe(II) matrix digested by alkali fusion was separated as Fe(II)Phen3(2+) (phen = 1,10-phenanthroline). Since 5% of the total iron was still detected as Fe(III)EDTA- and might disturb PIXE analysis of RE-EDTA-, itaconic acid was used as the spacer for Fe(III)EDTA- and RE-EDTA-. The fractions of RE-EDTA- were successfully analyzed off-line by a multielemental analytical method, PIXE [analytical result (3.62% (w/w) as RE2O3]; the nominal value was 3.37% (w/w) as RExOy.

Abstract
The relationship between soil water content and water use efficiency (WUE) of apple tree leaf was examined, and the mechanism of WUE variation was also studied by using pot-culture. The results showed that the WUE was upmost when soil water relative content (SWC) reached 52.0%. The increase of WUE when SWC decreased from 77.2% to 52.0% was mainly caused by the change of stomatal conductance. The decline of carboxylation efficiency resulted in the decrease of WUE when SWC decreased from 52.0% to 20.1%. The WUE returned up after being rewatered, but could not reach the control level within a week. The WUE decreased when the soil was waterlogged, but reached the control level in three days after being waterlogged. After the third day, the WUE decreased gradually with the extending of the time being waterlogged. On the sixth day being waterlogged, the carboxylation efficiency decreased.

Abstract
OBJECTIVE To investigate the effect of thyroxine upon the prevention of recurrence of Graves disease after treatment by antithyroid drugs. METHODS Sixty patients newly diagnosed as Graves disease were treated with methimazole for 6 months and then randomly distributed into three groups. Patient in group A and group C received small dose of methimazole plus L-T(4) 50 microgram/d, and patients in group B were treated with methimazole in small dose only. Twenty four months later, only L-T(4) 50 microgram/d, without methimazole, was administered to the patients of group A; methimazole in maintenance dose was administered continuously to the patients of group B, and patients in group C were treated with methimazole in maintenance dose plus L-T(4) 50 microgram/d. Such treatments lasted 6 months. Post-treatment follow-up survey was conducted to the three groups. RESULTS The titers of thyroid-stimulating Ab (TSAb) in groups A and C were lower than that in group B. However, the recurrence rates among the three groups (4/20, 20%; 4/20, 25%; and 4/20, 20% respectively) were not significantly different. CONCLUSION Both treatment of Graves' disease with methimazole plus L-T4 and treatment with prolonged use of methimazole cannot reduce the recurrence rate more effectively than treatment with only methimazole. The level of TSAb is not the only factor that influences the recurrence of Graves disease.

Abstract
To study its clinical significance, beta 2-microglobulin (beta 2-MG) in nasopharyngeal secretion was examined using radioimmunoassasy methods in 73 patients with nasopharyngeal carcinoma (NPC), 30 with chronic nasopharyngitis and 30 normal control subjects. In 31 NPC patients, the examination was repeated before and after radiotherapy. The average concentrations of beta 2-MG were 4.87 +/- 2.51 mg/L in NPC group, 1.05 +/- 0.64 mg/L in chronic nasopharygitis group, and 0.85 +/- 0.32 mg/L in the control. The beta 2-MG concentration was higher in the NPC patients than in both chronic pharyngitis patients and normal subjects (P < 0.01). The concentration was lowered down in NPC patients after radiotherapy, and remained high when the treatment failed to control the condition. It seems that beta 2-MG level in nasopharyngeal secretion is closely related to the prognosis and recurrence of nasopharyngeal carcinoma.

Abstract
Abstract
A competitive protein-binding assay for cyclosporine based on use of the intracellular cyclosporine-binding protein cyclophilin (CYP) was used to measure cyclosporin A (CsA) and its bioactive metabolites in whole blood. CYP from cytoplasmic extracts or erythrocyte lysates was applied in the binding assay with use of [3H]CsA as tracer and charcoal adsorption for separating bound from free tracer. Binding affinities of various CsA analogs and metabolites correlated well with their reported in vitro immunosuppressive activities. The assay detected as little CsA as 50 micrograms/L (1 g = 0.832 mmol of CsA), analytical recovery was greater than 80%, and CVs were less than 8% for intra-assay and less than 11% for interassay precision in the range of 150-1000 micrograms/L. We used this assay to measure CsA concentrations in blood and compared the results with those measured by HPLC or by CsA-specific (monoclonal) and CsA-nonspecific (polyclonal) radioimmunoassays. Binding assay results were, in nearly all cases, less than those measured by the nonspecific RIA and frequently greater than 20% above the values determined by the CsA-specific assays. Individual patients had pronounced differences in the relative proportions of CsA, CYP-binding (bioactive) metabolites, and cross-reacting CsA metabolites. Because the presence of bioactive metabolites may considerably contribute to the immunosuppressive activity of CsA, we consider the binding assay clinically useful for measuring CsA in biological fluids.
