OBJECTIVETo investigate the semen quality of cancer patients and search for a better way of sperm cryopreservation for them.

METHODSWe retrospectively analyzed the quality of the semen from 43 cancer patients under cryopreservation in the Sperm Bank of Zhejiang Province, and compared the semen parameters between the cancer patients and 248 normal donors as well as between the testicular cancer cases (n=22) and non-testicular cancer cases (n=21).

RESULTSThe cancer patients exhibited significantly lower semen quality than the normal donors as in sperm concentration (60.90 x 10(6)/ml vs 74.27 x 10(6)/ml), progressive motility (41.07% vs 51.79%), and recovery rate (49.98% vs 57.33%) (all P <0.05). Furthermore, the progressive sperm motility and sperm recovery rate after freezing were significantly decreased in the testicular cancer cases (15.68% and 42.81%) than in the non-testicular cancer cases (28.36% and 57.53%) (both P <0.05).

CONCLUSIONSemen quality declines in cancer patients, and therefore early sperm cryopreservation is essential for them. Due to the poor sperm motility and recovery rate of testicular cancer patients after freezing, further investigation is required on the improvement of sperm cryopreservation methods.

? AlM: To examine choroidal thickness and its relationship with axial length and spherical equivalent by spectral domain optical coherence tomography ( SD -OCT ) in patients with myopic choroidal neovascularization ( mCNV) .
?METHODS: We prospectively recruited 30 cases of mCNV in Beijing Anzhen Hospital from October 2010 to December 2014. SD-OCT was used to measure choroidal thickness subfoveally and at 1. 5mm superiorly, inferiorly, nasally and temporally ( SFCT, SCT1. 5mm , lCT1. 5mm , NCT1. 5mm , TCT1. 5mm ) . Paired t- test was conducted to assess the difference of spherical equivalent, axial length and choroidal thickness between mCNV group and controls. Logistic regression analysis was performed to evaluate the correlation between spherical equivalent, axial length, choroidal thickness and mCNV.
?RESULTS: The difference of spherical equivalent and axial length between mCNV group and controls was not significant (P>0. 05). lnferior was decreased in mCNV group compared with controls (140. 85±33. 46μm vs 168. 95±45. 36μm). The difference was significant (P=0. 008). Logistic regression demonstrated that decreased choroidal thickness ( lCT1. 5mm ) at inferior location was associated with mCNV (OR=2. 12;95%CI 1. 35~3. 28;P=0. 02).
?CONCLUSlON: The decrease of lCT1. 5MM may be one of the risk factors of mCNV.

Objective To observe the changes of hippocampal NogoA-NgR1 signaling on postoperative cognitive function (POCD) in aged mice, and explore the potential underling mechanism.Methods Isoflurane anesthesia and laparotomy were applied to establish the POCD model.Forty aged male C57BL/6 mice were randomly divided into the following four groups (n=10): group O2+saline (group OS), group O2+NEP1-40 (group ON), group isoflurane anesthesia+laparotomy surgery+saline (group SS), and group isoflurane anesthesia+laparotomy surgery+NEP1-40 (group SN).Cannula placement was performed into lateral ventricle 7 days before the surgery.Animals were subjected to an administration of NEP1-40 (20 μg/2 μl) or isochoric saline via intracerebroventricular injection once daily for 8 consecutive days, injection was given from 2 h before isoflurane anesthesia to the last behavioral test.Open field test was performed at 5th d after operation.Contextual and cued fear conditioning training and testing were exhibited at 6th and 7th d after operation, respectively.The hippocampus was harvested 2 h after the behavioral test.Western blot was used to detect the expressions of NogoA, NgR1, RhoA, ROCK2 and GAP43.Golgi staining was applied to measure the changes of dendritic spines in hippocampal CA1 area.Results Compared with the groups OS and ON, the freezing time in the contextual fear conditioning test was significantly decreased, the contents of NogoA, NgR1, RhoA and ROCK2 were significantly increased, the content of GAP43 and the number of dendritic spine were significantly decreased in group SS (P<0.05).Compared with the group SS, the freezing time in the contextual fear conditioning test was significantly increased, the contents of RhoA and ROCK2 were significantly decreased, the content of GAP43 and the number of dendritic spine were significantly increased in group SN (P<0.05).Conclusion Over-activated of hippocampal NogoA-NgR1 signaling participated in the pathogenesis of POCD in aged mice.

Objective To study the effects of citrullinated vimentin (cVim) on the maturation and immunologic function of dendritic cells (DCs) from rheumatoid arthritis (RA) peripheral blood.Methods In the present study,mononuclear cells were isolated from the peripheral blood of patients with RA and cultivated in media containing GM-CSF and IL-4 to generate immature DCs (imDCs).The imDCs generated were stimulated with citrullinated vimentin and vimentin.LPS was used as the positive control and PBS was used as the negative control.The expression of surface molecules on the DCs,such as CD14,CD80,CD83,CD86,MHC Ⅰ and MHC Ⅱ were analyzed with FACS.The capability of the stimulatory activity of the DCs on allogeneic T cells in mixed reaction was tested by MTS.t-test was used for statistical analysis.Results Compared to untreated DCs,DCs treated with LPS increased the expression levels of MHC Ⅱ,CD80,CD83 and CD86 (1.07±0.14,1.25±0.13,1.90±1.08,2.44±0.65,P＜0.05),while cVim increased the expression levels of MHC Ⅱ ( 1.18±0.09,P＜0.05) and CD83 ( 1.97±0.99,P＜0.01 ),and Vim decreased the expression levels of CD80 (0.82±0.18,P＜0.01 ).It was demonstrated that the expression levels of MHC Ⅱ on DCs pulsed with cVim were significantly higher than that of the DCs with LPS,but the expression levels of CD80 and CD86 were not significantly different.The expression levels of MHC Ⅱ and CD83 on DCs pulsed with cVim were significantly higher than that of the DCs with Vim.The mixed lymphocyte reaction showed that the DCs induced by LPS and cVim trigerred the proli-feration of allogenic T cells obviously.Conclusion This result suggests that cVim could promote the phenotypic maturation of DCs and increase the expression of costimulatory molecules.

OBJECTIVETo investigate the risk factors of pinhole infection in the fractured lower limbs after external fixation.

METHODSThe case-control study was designed. From May 2009 to May 2014, the clinical data of 272 patients with lower limb fracture treated by external fixation device were collected. All the patients were divided into two groups according to post-operative pinhole infection. There were 29 cases in the case group including 23 males and 6 females. The age of patients in case group ranged from 25 to 77 years old,with the average age of (53.41 ± 12.77) years old. There were 243 cases in control group including 217 males and 26 females. The age of patients in the control group ranged from 27 to 78 years old, with the average age of (48.71 ± 11.87) years old. There were nine risk factors observed in our study including age, gender, fixed time by external fixation device, diabetes, time in bed, smoking, operation condition of other parts in the body, infection condition of other parts in the body.

RESULTSThe results of univariate analysis showed that there were statistically significant differences among age (χ² = 15.708, P < 0.001), fixed time by external fixation device (χ² = 11.940, P < 0.001), severity of the lower limb fracture (χ² =15.438, P < 0.001), diabetes (χ² = 8.519, P = 0.004) and time in bed (χ² = 7.165, P = 0.007) between case group and control group. The results of Logistic regression analysis showed that the risk factors of pinhole infection after fixed by external fixation device in the lower limb fracture were the advanced age (OR = 8.327, P < 0.001), fixed time by external fixation device (OR = 6.795, P < 0.001), diabetes (OR = 4.965, P = 0.001) and time in bed (OR = 4.864, P = 0.008).

CONCLUSIONThe advanced age, long fixed time, diabetes and long time in bed could increase the risk of pinhole infection after external fixation in the lower limbs with fracture.

OBJECTIVETo explore the growth patterns and simple mathematic models of height and weight of Chinese children.

METHODSThe original data had been obtained from two national representative cross-sectional surveys which were 2005 National Survey of Physical Development of Children (under 7 years of age) and 2005 Chinese National Survey on Students Constitution and Health (6 - 18 years). Reference curves of height and weight of children under 7 years of age was constructed by LMS method, and data of children from 6 to 18 years of age were smoothed by cubic spline function and transformed by modified LMS procedure. Growth velocity was calculated by smoothed values of height and weight. Simple linear model was fitted for children 1 to 10 years of age, for which smoothed height and weight values were used.

RESULTS(1) Birth length of Chinese children was about 50 cm, average length 61 cm, 67 cm, 76 cm and 88 cm at the 3rd, 6th, 12th and 24th month. Height gain was stable from 2 to 10 years of age, average 6 - 7 cm each year. Birth length doubles by 3.5 years, and triples by 12 years. The formula estimating average height of normal children aged 2 - 10 years was, height (cm) = age (yr) x 6.5 + 76 (cm). (2) Birth weight was about 3.3 kg. Growth velocity was at peak about 1.0 - 1.1 kg/mon in the first 3 months, decreased by half and was about 0.5 - 0.6 kg/mon in the second 3 months, and was reduced by a quarter, which was about 0.25 - 0.30 kg/mon, in the last 6 months of the first year. Body mass was up to doubles, triples and quadruple of birth weight at about the 3rd, 12th and 24th month. Average annual gain was about 2 kg and 3 kg from 1 - 6 years and 7 - 10 years, respectively. The estimated formula for children 1 to 6 years of age was weight (kg) = age (yr) x 2 + 8 (kg), but for those 7 - 10 years old, weight (kg) = age (yr) x 3 + 2 (kg).

CONCLUSIONSGrowth patterns of height and weight at the different age stages were summarized for Chinese children, and simple reference data of height and weight velocity from 0 to 18 years and approximate estimation formula from 1 - 10 years was presented for clinical practice.
