ABSTRACT
S100A9 is a calcium-binding protein that plays an important role in the progression of malignant tumors. Related studies have confirmed that the abnormal expression of S100A9 is closely related to the proliferation, metastasis and prognosis of breast cancer, while whether S100A9 can be used as a marker for the diagnosis and treatment of breast cancer is still controversial. This article reviews the current research status of S100A9 and its application prospect in the development, progression, diagnosis and treatment of breast cancer.
ABSTRACT
OBJECTIVE: To establish a headspace gas chromatography-mass spectrometry method for the determination of 14 chlorinated hydrocarbons in urine. METHODS: The urine sample 4.00 mL and anhydrous sodium sulfate 3.00 g were added into a 10.00 mL headspace bottle, then the headspace bottle was maintained at 70 ℃ for 40.0 min. After headspace pretreatment, 14 chlorinated hydrocarbons in headspace air were separated in the DB-5 MS capillary column of the gas chromatography and detected by mass spectrometer. RESULTS: There was a good linear relationship of 14 chlorinated hydrocarbons in urine in the range of 0.62-1 630.00 μg/L. The linear correlation coefficient was greater than 0.999 0.The minimum detectable concentration was 0.19-0.43 μg/L and the minimum quantitative concentration was 0.62-1.44 μg/L. The average recovery rate was 89.8%-107.1%. The within-run relative standard deviation(RSD) was 4.0%-8.5% and the between-run RSD was 6.3%-9.1%. Urine samples can be stored at 4 ℃ or-8 ℃ for 3 days and below-20 ℃ for 7 days. CONCLUSION: This method is rapid, simple, sensitive, accurate and has little interference,which can be used as a method for detecting 14 kinds of chlorinated hydrocarbons in urine samples of patients with occupational poisoning.

ABSTRACT
Objective To explore the relationships between the sleep/wake-up patterns and temperament in preterm infants.Methods The developmental characteristics of sleep/wake-up patterns and temperament in preterm infants aged 4 months at corrected gestational age in their own home environments were described.The 23 relatively low-risk preterm infants were enrolled in this study.The sleep/wake-up data was collected with actigraphy.The temperament was assessed by Chinese Infant Temperament Questionnaire.Results Among the 23 infants,there were 13 coordinated difficult(D) type and 10 coordinated easy(E) type.The number of night wake-up in the coordinated D-type preterm infants[(2.78 ±0.01) times] were significantly more than that of coordinated E-type ones[(2.60 ± 0.03) times] (t =3.285,P =0.001).The longest continuous sleep time of coordinated D-type preterm infants [(4.20 ± 1.21) h] was significantly less than that of coordinated E-type ones[(4.41 ± 1.14) h] (t =3.374,P =0.001).There were no significant differences in daytime sleep duration,the number of naps,bedtime,sleep latency,nighttime sleep duration,the 24 hour sleep duration and morning awaking time between the two groups (all P ＞ 0.05).After the sex factor was controlled,there was a positive correlation between emotional nature and sleep latency at night (r =0.599,P =0.032).There was also positive correlation between persistence and the number of naps in daytime (r =0.439,P =0.035).Conclusions Preterm infants with different temperament types have different number of night wake-ups and the longest continuous sleep time.The emotional nature and persistence are associated with sleep latency at night and number of naps in daytime respectively.The parents of preterm infants should change their child rearing behaviors to improve sleep quality of the preterm infants.
ABSTRACT
<p><b>OBJECTIVE</b>To understand the infantile nocturnal sleep-wake pattern developmental trajectory with Actiwatch, which would benefit the clinical assessment of infantile sleep.</p><p><b>METHOD</b>This study was a longitudinal study conducted between 7 Oct, 2009-30 Oct, 2011 in 10 hospitals of 9 cities of China ( Beijing, Xi'an, Qingdao, Wuhan, Changsha, Chongqing, Huzhou, Xiamen and Liuzhou). Actiwatch was used to track the sleep-wake pattern development trajectory of healthy infants in the first year of life in the home setting. Participating infants were followed up at 10th day and 28th day during the first month, and then monthly from the second to the sixth month after birth, and then at ninth and twelve months of age respectively. Meanwhile, infantile sleep was observed continuously for about 60 hours at each visit. According to the characteristics of repeated measurement data of this study, two-level random effect model was adopted to analyze the trend of infantile nocturnal sleep-wake parameters changing with age, and the gender difference.</p><p><b>RESULT</b>A total of 473 healthy infants were included in this study, among whom 246 (52.0%) were boys, and 227 (48.0%) were girls; 355 (75.1%) infants completed the whole year follow-up survey. With infants' age increasing, the latency of infants' nighttime sleep onset decreased from 66.8 minutes on 10th day to 15.5-18.7 minutes at 6-12 months of age. The number of night wakes also decreased with age, while uninterrupted sleep periods lengthened with age. On the 10th day, there were 3.0 times of nightwaking on average, and the longest continuous sleeping interval lasted for 227.6 minutes on average. At 12-month of age, infants could sleep continuously for 350.9 minutes at most on average, while the number of nightwaking decreased to 1.6 times per night on average. Generally, nighttime sleep efficiency increased from 66.3% on the 10th day to 86.3% at 12-month of age. The differences of sleep-wake patterns between boys and girls presented as boys' nocturnal longest uninterrupted sleep period was 19 minutes shorter(266.6 vs. 285.6 min), and the average nighttime sleep efficiency was 2.2% lower (74.2% vs. 76.4%) compared with girls respectively. And the differences of sleep efficiency between boys and girls reduced gradually along with the growth.</p><p><b>CONCLUSION</b>During the first 6 months after birth, infantile sleep-wake pattern undergo obvious change.

ABSTRACT
s: The onset of Crohn’s disease (CD) is the interaction of environment, heredity, infection, immune and other factors. It is also closely related to abnormal immune functions. Without special treatment, CD is identified as a modern refractory disease. By syndrome differentiation and treatment, traditional Chinese medicine (TCM) can effectively relieve disease conditions, improve the quality of life and reduce side effects of modern medication. The core compatibility ofBai-Zhu andFu-Ling can reinforce spleen-qi and dispel dampness, which met the common pathogenesis of CD. Therefore, the combination is comprehensively used in the compound prescription. Our previous study found thatBai-Zhu Fu-Ling decoctioncan reduce the vasoactive intestinal peptide (VIP) of animal model of spleen-qi deficiency, downregulate VIP receptors, decrease the affinity of VIP receptors and improve animal model’s sIgA. To further clarify the effects about neurotransmitters and their correlation with the immune system in the pathogenesis of CD and the intervention mechanism treated by different proportional compatibility ofBai-Zhu Fu-Ling decoction, we studied influences of the decoction on related transmitters of nerve- immune network and functions of receptors, as well as cytokine secretion and signal transduction of TLR4-NF-κB. Our studies can provide references and foundations to further explore TCM treatment of CD.
ABSTRACT
Objective:To evaluate the diagnosis significance of breast mammography assisted by hook-wire localization biopsy for BI-RADSⅣand above negative or non-palpable breast lesions. Methods:A total of 48 cases of mammary molybdenum target with BI-RADSⅣlevel and above but with clinical-touched negative or non-palpable breast lesions (including 4 bilateral lesions and 44 uni-lateral lesions;total of 52 lesions) were used in the mammography aided by hook-wire localization biopsy. Results:Among the 52 le-sions, 13 cases were malignant lesions (single), 6 cases were at Stage 0 (accounted for 46.15%), 5 cases were in Stage I (38.46%), and 2 cases were in StageⅡ(15.39%). The remaining 39 cases were benign lesions. Results showed that the detection rate for breast cancer was 25.0%. A total of 39 cases of benign lesions and 10 cases of malignant lesions were found among mammography BI-RADSⅣpa-tients. Zero cases of benign lesions and 3 cases of malignant change were found among BI-RADS Ⅴ patients. The positive rates of breast cancer among BI-RADSⅣandⅤpatients were 25.64%and 100%, respectively. Conclusion:Breast mammography assisted by hook-wire localization biopsy could precisely excise both BI-RADSⅣandⅤnegative/non-palpable breast lesions. This technique can also improve the quality of life and prognosis of patients. It is a safe, accurate, and low-cost diagnostic method. Thus, breast mammogra-phy assisted by hook-wire localization biopsy must be widely used in clinical applications in China.

Objective To explore the level of hypersensitive C-reactive protein (hs-CRP)in the patients with acute ischemic stroke(AIS)and its clinical significance.Methods The BNⅡhighly sensitive automatical scattering turbidimetric immunity analy-zer was adopted to detect serum hs-CRP level in 64 cases of AIS and contemporaneous 32 individuals with healthy physical examina-tion as the control group.The data of AIS cases were retrospectively analyzed.Results The positive rate of hs-CRP was 53.3% in the AIS group and 9% in the control group with statistically significant difference between them(P <0.05);the overall levels of hs-CRP in the AIS group was in inconformity to the normal distribution,the median was 4.26mg/L,which in the control group was (0.99 ± 0.72 )mg/L,there was statistically significant difference between them (P < 0.05 );the average level of hs-CRP was (5.03±1.51)mg/L in the AIS male group and (2.79 ± 1.09)mg/L in the AIS female group,the difference between them had sta-tostical significance(P <0.05).Conclusion The serum hs-CRP level in the AIS patients is higher than that in the healthy crowd with statistical difference(P <0.05).The age and sex may be the causes influencing serum level of hs-CRP in the AIS patients.The average age in the AIS patients with positive hs-CRP is higher than that with negative hs-CRP.Middle-aged and elderly people with hypertension and diabetes are much more dangerous than healthy people in getting AIS.
ABSTRACT
This study was aimed to observe the effect of Bai-Zhu Fu-Ling (BZFL) Decoction in different proportion-ing on VIP and VIPR1 in Crohn's disease (CD) rats with spleen deficiency syndrome, in order to further explore the immunologic mechanism of BZFL Decoction on CD. The CD rat model with spleen deficiency syndrome was estab-lished using exhaustion and hunger. The model rats were treated by BZFL Decoction with different proportioning, and immunohistochemistry (IHC) was used to detect the expression of VIP and its receptor in colon tissues. The results showed that comparing to the blank control group, the level of VIP and its receptor of the model group significantly increased (P< 0.05). Comparing to the model group, the level of VIP and its receptor in BZFL Decoction B5 group (Rhizoma A tractylodis Macrocephalae:Poria = 12:15), B6 group (Rhizoma A tractylodis Macrocephalae:Poria = 15:12) and B7 group (Rhizoma A tractylodis Macrocephalae:Poria = 18:9) was significantly decreased (P< 0.05). It was con-cluded that the effect of BZFL Decoction of B5 group, B6 group and B7 group was better than other groups in VIP and its receptor which can regulate the VIP and its receptor, inhibit the releasing of inflammatory factors and reduce intestinal inflammation injury.
ABSTRACT
Intrahepatic cholestasis of pregnancy (ICP) is an unique complication in pregnancy, which usually manifests in the second or third trimester, and mainly harms the fetus. Its pathogenesis is not yet clear, and placental pathological changes are insufficient to explain the clinical phenomenon.Recent studies had shown that the important cause of perinatal deaths may be the damage to the placental structure and function caused by the high bile acid level. In addition, the change of placental structure and function, umbilical cord factors, and endocrine changes can also cause the fetal development and intrauterine hypoxia. In recent years related researches focus on the toxic effect of bile acid on fetus heart, lungs, brain, liver, and other important organs, the placental vascular pathology, hemodynamic changes, umbilical cord blood vessel factors and the endocrine changes.

ABSTRACT
To discuss the diagnosis and therapy of congenital vesicovaginal fistula (VVF). We reported 1 case of pregnancy and congenital VVF and summarized the pathogenesis and characters. Congenital VVF is extremely rare and characterised by continuous urinary leakage,cyclical hematuria with severe suprapubic pain. It is always associated with other urinary tract abnormalities, urinary tract infection and stone. The pathogenesis is related with genetic, environment, drugs, radiation and incomplete fusion of mullerian. The diagnosis relies on clinical manifestation and radiological examinations.Surgical resection is the key to treatment. Pregnancy and congenital VVF is extremely rare and always misdiagnosised associated with other urinary tract abnormalities. Early diagnosis and making sure the location, size and relationship with other tissues are important. Reasonable preoperative preparation, surgical and postoperative surgical care are the key for treatment.

ABSTRACT
Objective To explore the characteristics of speech,phone and cognition development of infants and toddlers with mild hearing loss and to study the effect of early intervention.Methods Speech and cognition abilities of 59 children with mild hearing loss,aged 8 months to 2 years and 10 months old were assessed and 34 normal hearing children,aged 8 months to 2 years and 9 months old were compared.Eighteen children with hearing loss were fitted with hearing aids and received speech therapy for 6 months.The participants' speech and cognition development were evaluated with Gesell developmental scale.The phone test was adopted to assess the speech sound development in 59 children with mild hearing loss.Results Of the 59 children with mild hearing loss,37 were judged with normal speech development quotients(DQ),8 with abnormal speech DQ,14 suspect of abnormal speech DQ.The hearing loss in cases with abnormal speech DQ was more serious than that in cases with normal speech DQ(P＜0.05).The speech DQ and personal-social behavior DQ of children with mild hearing loss were significantly lower than normal children(P＜0.01).The speech DQ and personal-social DQ on Gesell developmental scales were significantly higher in 18 children received early intervention,compared with those who did not receive intervention (P＜0.01).Six cases with mild hearing loss demonstrated phone errors,but no abnormal manifestations in tone.After early intervention the phone of those with mild hearing loss improved significantly.No significant difference in gross motor,fine motor and adaptive ability was observed between the children with mild hearing loss and those with normal hearing(P＞0.05).Conclusion The speech ability of children with mild hearing loss is significantly lower than those with normal hearing.Some mild hearing loss children show phone errors.Mild hearing loss affect the adaptation and communication abilities of mild hearing loss children significantly.Early intervention can significantly improve the speech,phone,adaptation and communication abilities of children with mild hearing loss.
ABSTRACT
Objective To compare the effect of perineal cleansing with the potassium permanganate or sterile water on mid- stream urine culture. Methods Mid- stream specimens of urine were obtained from inpatients in our hospital between January 2002 and December 2006. All these patients may be diag-nosed as urinary tract infection. The urine specimens were divided into the potassium permanganate group (n=1572, the sterilization group) and the sterile water group (n=544). The change of positive and contami-nation rate of mid-stream urine culture from the specimens was observed. More than two kinds of germs in one urine specimen were defined as contamination. Results 830 patients with urinary tract infection had been enrolled. 2116 specimens were collected and 531 strains of causative organism were detected. The positive rate of the sterilization group and the sterile water group was 20.04% and 39.71%, respectively,and such difference was significant. The rate of identical causative organism from the same patient whose spec-imen was cultivated twice in the sterilization group was 0.012% and the rate was 0.105% in the sterile water group. The difference was significant. The rate of different or one kind of causative organism from the same patient whose specimen was cultivated twice in these two groups hadn't significant deviation. The contami-nation rate of the sterilization group (0.028%) was significantly higher than that of the sterile water group (0.007%). Conclusions Perineal cleansing with sterile water can reduce the false negative rate of mid-stream urine culture without increasing the contamination rate. Potassium permanganate sterilization is re-sponsible for the high false-negative in mid-stream urine culture.

ABSTRACT
BACKGROUND: Hibiscus Mutabilis L. Is a very effective Chinese traditional herb for non-specific inflammation in the clinic adopted by Professor Wei Zhixin, the eminent expert in Traumatology Department in China, lasting for near 60 years. In order to explain its pharmaceutical mechanism, the research of Hibiscus Mutabilis L. Was carried on in the model of ischemic reperfusion injury to explain its mechanism on anti-inflammation.OBJECTIVE: To observe the protection of the effective fraction of Hibiscus Mutabilis L. (MFR) on renal ischemic reperfusion injury in rats to probe into the mechanism of MFR on anti-inflammation.DESIGN: Randomized and controlled study on experimental animal.SETTING: A Municipal Institute of Traumatology and Orthopedic Department.MATERIALS: The experiment was performed in the Key Experiment Room (Institute of Traumatology and Orthopedic Department, Shanghai) of State Administration of Traditional Chinese Medicine, in which, 55 male Wistar rats were employed.METHODS: The rat model of renal ischemic reperfusion was adopted and MFR was applied for gastric perfusion to determine serum blood urea nitrogen(BUN) and serum creatinine(Scr) and the level of interleukin-1 (IL-1).MAIN OUTCOME MEASURES: ① Changes in serum BUN and Scr; ②Effect of MFR on level of serum IL-1.RESULTS: After MFR treatment, the renal function was improved remarkably after ischemic reperfusion in rats. In sham-operation group, serun BUN was (6.72 ± 1.30) mmol/L and serum Scr was (38.40 ± 6.23) μmol/L. In 24hours of reperfusion after one-hour ischemia, BUN was(60. 72±4.64)mmol/L in the control and(47.34 ± 8.32) mmol/L in the MFR treatment group, and the significant difference presented between two groups(t=2.562, P ＜ 0.05) .Serum Scr was(347.95±95) μmol/L and(518.20 ± 41.15) μmol/L in the treatment group and the control respectively, indicating significant difference ( t = 3.69, P ＜ 0.01 ) . Concerning to the effect on IL-1, in 1 hour of reperfusion after 1 hour renal ischemia,IL-1 was( 122.79 ±27.56) ng/L in the MER treatment group,(180. 28 ±33. 15) ng/L in the control group, indicating that IL-1 level in the treatment group was remarkably superior to that in the control group(t = 2.98, P ＜ 0.05). In 3 hours of reperfusion after 1 hour ischemia, level of IL-1 in the treatment group and control group was(15.58±8.59) ng/L and (34. 13±± 10. 02) ng/L respectively, indicating significant difference( t = 3.14, P＜ 0.05).CONCLUSION: MFR provides protection on renal ischemic reperfusion injury, which probably is related to its inhibition on IL-1 formation.
