Catch-up growth,a phenomenon that occurs after a short time growth-inhibiting condition,has been proved to be strongly associated with insulin resistance.But the mechanism of insulin resistance in the process of catch-up growth is not clear.

The traditional view that vitamin D is mainly involved in bone metabolism and calcium and phosphorus homeostasis,and bone-related diseases such as osteoporosis related.However,some recent studies have shown that vitamin D plays a key role in obstetrics and gynecology diseases,particularly,endometriosis and ovarian cancer,preeclampsia and gestational diabetes mellitus (GDM) in polycystic ovary syndrome influence (PCOS).Advances in vitamin D article and on the relationship between gynecological and obstetrical diseases were reviewed.

Noninvasive continuous positive airway pressure (CPAP) for the ventilation treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS) is the first-line treatment method. This article aims to describe the effect of surgical operation especially for the UPPP in the individualized comprehensive treatment of OSAHS and the importance of surgical technique. Lower compliance is the bottleneck of CPAP therapy in clinical application, for the OSAHS patients with treatment failure in CPAP or those cannot accept CPAP therapy, when with no other ideal instrument therapeutics, accurate diagnosis of position in airway obstruction with an adequate surgical operation is the treatment,of choice. Surgical operation is particularly important either as a fore-lying means to improve the CPAP treatment compliance or as an independence treatment method of OSAHS. The pharyngeal cavity is the most common obstructive plane in patients with OSAHS. The operation of traditional UPPP aiming at the expansion of pharyngeal cavity is the classics surgery to solve obstruction in this plane, the lower operation effective rate is the main reason of restriction in its development. How to improve the effective rate of surgical treatment of OSAHS is our surgical goal. The effective rate of surgical operation treatment in OSAHS rely on the following sides: to follow the OSAHS individualized comprehensive treatment principle, reasonable choice of surgical operation indication, the precise localization diagnosis of upper airway obstruction, adequate surgical operation and skilled surgical techniques.

The model of vaginal candidiasis in Kunming mice was constructed in order to search for the optima construction conditions and provide an economic animal model of Candida albicans (C. albicans) vaginitis. Estrogen benzoate (E2) was given to mice at different concentrations ranging from 0.0 to 0.05 mg/mouse (4 levels) beginning 72 h prior to vaginal inoculation, then mice were inoculated intravaginally with various concentrations of stationary-phase C. albicans blastoconidia (ATCC90028) (5 levels) in 20 microL of phosphate-buffered saline (PBS) in each E2 level. General state, scores of genital pathology, the hyphae and vaginal fungal burden (CFU) in vaginal lavage fluid, the hydrops rate of uterus and vaginal tissues for pathological section in mice were observed and obtained at day 2, 4, 7, 14 and 21 after inoculation. The results showed the infection rate in mice was related to the dosage of E2 and concentration of C. albicans blastoconidia. Additionally there was better cross-effect between the two treated factors. The infection rate was about 80% on the day 4, and could reach 100% on the day 7 until the end of experiment after inoculated intravaginally in groups of E2I3, E2 0.025 mg/mouse injected hypodermically and inoculated intravaginally with 5 x 10(4) C. albicans blastoconidia, and large amount of hyphae and blastoconidia could be observe in superficial layer tissue and canal of vaginal by PAS. From the results in our experiment it was concluded that E2I3 was the optima construction condition in kunming mice.

To investigate the effects of the free radical, 1,1-Diphenyl-2-picylhydrazyl, on cochlear blood flow, 20 guinea pigs were divided into 3 groups at random, 6 for control group, 6 for 1 mmol/L group and 8 for 0.1 mmol/L group. 2 microliters vehicle or drugs were dropped into round window membrane (RWM). Cochlear microcirculation was monitored by laser Doppler flowmeter (LDF), and mean arterial blood flow (MABP), which was transferred by pressure conductor sensor and preamplifier, was simultaneously recorded on the computer. Our results showed that MABP was stable throughout the experiment. Cochlear blood flow (CBF) increased by 10.32% (P < 0.05) in 1 mmol/L group, and decreased by 4.89% in 0.1 mmol/L group (P < 0.05). In control group cochlear microcirculation showed no significant changes. It is concluded that DPPH exerted effects on cochlear microcirculation.

BACKGROUND:Bone defects often occur after the reduction of periarticuar fractures, and bone grafting is required to fil bone defects, thereby to make the early support of articular surface and prevent the col apse and shift of the articular surface. Al ograft cancellous bone is the transplant material for the treatment of bone defects, but its osteogenesis ability is poor. Autologous red marrow has osteogenesis ability. Therapeutic efficiency of al ograft cancellous bone combined with autologous red marrow for periarticular fractures is stil yet to be
assessed.
OBJECTIVE:To study clinical effect of locking plate fixation and al ograft cancellous bone combined with autologous red marrow in the treatment of periarticular fractures.
METHODS:Forty-three cases of periarticular fractures were incorporated into the Orthopaedics Department of the Third Hospital of Hebei Medical University. After cutting the articular surface anatomical y, composite particles of the red marrow and al ograft cancellous bone were implanted into bone defects, and then, an anatomic locking plate was used. Medial lateral or bilateral locking plate was used for tibial plateau fractures. Dorsal or volar locking plate was used for distal radius fractures, and distal tibial medial or lateral locking plate was used for distal tibial fractures.
RESULTS AND CONCLUSION:Forty-three patients were fol owed up for 12 months to 6 years, an average of 4.3 years. X-ray films and CT scans review showed that 43 patients’ col apse fracture al reached bony union. Fresh fracture healing time was 2-6 months, an average of 4 months;the healing time for old fracture was 3-7 months, an average of 5.5 months. After bone grafting, 43 patients al had no significant immune rejection, two cases showed more wound exudates, and the wound was healed by dressing after 2 weeks. One case had wound infection, the wound was healed after 4 weeks of draining and dressing, and the infection had no recurrence fol owing up for 4 years and 1 month. Forty patients were satisfied with bone grafting, accounting for 93%, and three cases dissatisfied, accounting for 7%, based on Mankin and Komender’s standard assessment. The results confirmed that al ograft cancellous bone combined with autologous red marrow transplantation can play a supporting role in treating periarticular fractures to prevent the col apse of the articular surface and fracture displacement, and to provide reconstruction materials for periarticular defects. Its long-term goal is fracture healing.

Objective To investigate and analyze the relationship of the level of high-sensitivity C-reactive protein (hs-CRP) and carotid artery atherosclerosis with acute cerebral infarction (ACI).Methods Fifty-nine patients with ACI were assigned as experimental group and thirty healthy people as control group. The serum level of hs-CRP was measured, and the carotid plaques and the changes of carotid intimal-medial thickness (IMT) were examined by color Doppler ultrasonography.Then the relationship between the serum level of hs-CRP and the severity of disease was analyzed.Results The serum level of hs-CRP was higher in ACI group than in control group [(5.96± 1.52)mg/L vs. (1.78±1.02) mg/L, t=15.383, P＜0.01]. The detection rates of carotid plaques and the increased carotid IMT were higher in ACI group than in control group [77.97% vs. 36.67%, x2 =12.92, P＜0.01; (1.18±0.17) mm vs. (1.02±0.15) mm, t=4.544, P＜0.05]. The hs-CRP levels were higher in the severe cases [(15.68±1.45) mg/L] than in moderate cases [(4.16±1.39)mg/L] and mild cases [(1.88±0.34) mg/L, t=37. 217, 25. 243, both P＜0.01]. Conclusions The elevated levels of hs-CRP have overt clinical significances for the atherothrombotic cerebral infarction. Early determination of hs-CRP is helpful to evaluate patient's condition and prognosis.

Objective:To investigate the clinicopathological characteristics of lung cancer patients with axillary lymph node metastasis (ALNM). Methods:The clinical data of 91 lung cancer patients with ALNM who were treated in Zhejiang Cancer Hospital from January 1st, 2007 to December 31st, 2013 were retrospectively analyzed. The relevance of the sites of the tumor site, local lymph node, and ax-illary lymph node was checked by contingency table. Survival rates were calculated by the Kaplan-Meier method and compared by a log-rank test. Cox proportional hazards model was applied to analyze the prognostic factors. Results:The proportion of lung cancer pa-tients with ALNM was 0.63%, and the patients were often presented with adenocarcinoma, peripheral tumor type, pleura invasion with pleural effusion, or chest wall invasion. A relationship between tumor sites, local lymph node sites, and axillary lymph node sites was observed. The median survival time of lung cancer patients with ALNM was 19.02 months, and the two-year survival rate is 62.64%. Patients identified with ALNM at the initial diagnosis reported poor prognosis (P=0.002). Cox regression analysis showed that the relative risk of death in patients with ALNM at initial diagnosis was elevated 2.18 times (95%CI:1.330?3.572, P=0.003). Conclu-sion:ALNM in lung cancer is rare, and it may involve through direct chest wall invasion and spread from supraclavicular and mediasti-nal lymph node metastasis or systemic origin. Patients detected with ALNM at the initial diagnosis indicated poor prognosis.
