AIM: To evaluate the relationship between axial length ( AL ) , corneal and lens refractive power, and the refractive error in children.
METHODS:Totally 44 children 88 eyes with refractive error who underwent retinoscopy with cycloplegia, to be measured spherical equivalent refractive error. Axial length was measured by a noncontact optical biometry ( ZEISS IOL-Master) , and corneal K and anterior chamber depth ( ACD) were also measured by the same machine. The refractive power of the lens was calculated by using the SRK formula. The patients were divided into 3 groups, myopia (SE<0), hyperopia (SE>+0. 50D) and emmetropia ( 0 to + 0. 50D ). Linear Correlation and Regression were used to evaluate the correlation among the optical parameters.
RESULTS:Totally 44 subjects, 88 eyes, average 9. 04±2.39 years, spherical equivalent (SE) -3. 50D to +8. 75D. Hyperopic AL was shorter than the other two groups ( P<0.05), same trend in lens power. No significant differences among the 3 groups in corneal K and ACD. There was a negative correlation between age and SE, SE and AL, SE and lens refractive power, and there was a positive correlation between age and AL, age and lens power.
CONCLUSION:As the children's growing up, SE trends to myopia, and AL becomes longer, and lens power is stronger.

Advocating green, nature, environmental protection, safety and the pursuit of efficacy are the trends of cosmetics in the world. In recent years, more and more Chinese herbal extracts with mild, high safety and small irritation are applied to cosmetics as the natural additives. This has become a new hot spot. The recent application advances of Chinese medicine raw materials in cosmetics are overviewed according to their main functions. This review will provide useful references for the future development and application of Chinese medicinal herbs cosmetics.

Objective To explore the correlation between hyperuricaemia and blood pressure, and blood lipid and glucose. Methods By using simple cluster sampling, 2 branch units from PetroChina Changqing Oilfield Company were selected, and all the 720 subjects with hyperuricaemia (HUA) were assigned to the HUA group; another 620 participants with normal uric acid (UA) level into the normal group. The correlation between blood uric acid and blood pressure,and blood lipid and glucose was assessed by Logistic regression. Results The odds ratio (OR) of those who had 1,2 or 3 abnormal status of hypertension,hyperlipidemia and impaired fasting glucose in the HUA group were much higher than the normal group (OR values were 4. 036,2. 562, and 4. 174, respectively). Logistic regression showed that male, systolic blood pressure ( SBP), GLU, total cholesterol ( TC), triglyceride ( TG), low-density lipoprotein cholesterol (LDL-C) were risk factors of H UA ( OR values were 7. 736,2. 309,1.721,2. 761 and 1. 411,respectively) ,while high-density lipoprotein cholesterol (HDL-C, OR = 0. 211 ) was a protective factor of HUA. Conclusions Gender,blood pressure and blood lipid may have correlation with blood UA. Multiple risk factors should be considered to improve the effectiveness of health education and health promotion.

Objective To observe the effect of Yiqi Huexue Recipe on the expression of TGF-β1 and TNF-α on serum and lung of rots with radiation-induced lung injury in different radiation time,and discuss the preventative and curative effect and mechanisms of Yiqi Huoxue Recipe.Methods 66 Wistar rats were randomly allocated into irradiation with Yiqi Huoxue Recipe-treated group(A group)irradiation group(B group),and normal control group(C group).The first two groups were irradiated at right hemithorax with a dose of 30 Gy/6 fractions(in 6 weeks).The levels of TGF-β1,and TNF-α on rat serum and lung were measured by ELISA and immunohistochemistry at the end of the 4th,6th,8th,12th,and 26th week after the first irradiation.Results TGF-β1,and TNF-α level on rats serum and lung in irradiation group showed an increase from the 4th week after the first irradiation,peaking at the 12th week,and descending at the 26th week.In A group,the levels of TGF-β1 and TNF-α were significantly lower from the 4th week than those of B group.Conclusions Yiqi Huoxue Recipe could inhibit the excretion of TGF-β1,and TNF-α and might play an important role in the prevention and curation of radiation-induced lung injury,which might be related to inhibiting the expression of TGF-β1 and TNF-α.

OBJECTIVETo study the clinicopathological characteristics of papillary cystadenoma of the epididymis.

METHODSUsing routine pathology and immunohistochemistry, we observed the surgically obtained samples from 2 cases of papillary cystadenoma of the epididymis, analyzed their pathological features and clinical presentations, and reviewed the related literature.

RESULTSThe 2 patients were both adult males. The tumors typically manifested as painless swelling in the epididymis, with occasionally dull pain and tenesmus in 1 of the cases. Pathologically, the lesions exhibited three morphological features, i. e., dilated ducts and small cysts surrounded by fibrous connective tissue, adenoid papillary hyperplasia into the cysts embraced by fibrovascular stroma, and acidophil substance present in the cysts. Immunohistochemistry showed that the tumors were strongly positive for CK8/18, CK7, and EMA, but negative for CK20, CEA, MC, Calretenin, P53, P63, SMA, VHL, and CD10, with the positive rate of Ki-67 <1%. Follow-up visits revealed good prognosis in both cases.

CONCLUSIONPapillary cystadenoma of the epididymis is a rare benign tumor in the male urogenital system, which may be accompanied by the VHL syndrome. Surgery is the first choice for its treatment.

OBJECTIVETo study the numbers and locations of spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient under the laparoscope.

METHODSFifty-seven varicocele patients received laparoscopic ligation of spermatic veins, during which we recorded the numbers and observed the locations of spermatic veins, testicular arteries, and spermatic lymphatic vessels.

RESULTSDuring the surgery, we identified 3.3 ± 1.2 spermatic veins, 1.4 ± 0.9 testicular arteries, and 4.3 ± 1.1 spermatic lymphatic vessels. No statistically significant differences were observed between the two side in the numbers of the spermatic veins, testicular arteries and spermatic lymphatic vessels (P > 0.05). The testicular arteries were seen on the exterior of the spermatic veins and winding around them, while the spermatic lymphatic vessels mostly between the veins.

CONCLUSIONThe spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient have their specific anatomic characteristics. Laparoscopic identification of these vessels may contribute to the surgical treatment of varicocele.
