There has been a growing number of prostate cancer patients in our country,and most of the patients suffer with bone metastases.Although more and more new drugs are reported for the treatment of prostate cancer,tumor local recurrence or metastasis occur within the 10 years after treatment.The diagnostic sensitivity of 18F-NaF PET/CT for bone metastases from prostate cancer is high.18F-NaF PET/CT not only can locate the lesion precisely,evaluate the drug efficacy quantitatively,but also can be used to follow up prostate cancer patients.This review is focused on the application of 18F-NaF PET/CT in bone metastases from prostate cancer.

OBJECTIVE:To observe the efficacy and safety of low-dose Progesterone injection combined with Baotai wuyou capsule in the treatment of threatened abortion. METHODS:107 patients with threatened abortion were retrospectively analyzed and divided into observation group(54 cases)and control group(53 cases)by different medication. All patients received bed rest orally taking folic acid and other measures. Meanwhile,control group was given Progesterone injection 20-40 mg,qd,intramuscu-larly injected. Observation group was given Progesterone injection 10-20 mg,qd,intramuscularly injected and given 4 Baotai wuy-ou capsule additionally,tid,taking with ginger decoction,no fish during the medication. The courses of 2 groups were 14 d. Clini-cal efficacy,hemostatic time,remission time of abdominal pain and backache in 2 groups were observed,and the incidence of ad-verse reactions during the treatment was recorded. RESULTS:The total effective rate in observation group was significantly higher than control group,hemostatic time,remission time of abdominal pain and backache were significantly shorter than control group, the incidence of adverse reactions was significantly lower than control group,with statistical significances (P<0.05). CONCLU-SIONS:Low-dose Progesterone injection combined with Baotai wuyou capsule shows good efficacy in the treatment of threatened abortion,which can shorten patients'hemostatic time,remission time of abdominal pain and backache,and reduce the incidence of adverse reactions,with good safety.

Objective To explore the ultrasonic diagnosis of fetal cleft palate.Methods By applying coronal,sagittal and transverse planes to scan the fetal facial anatomy routinely, 2125 pregnant women with 20 odd weeks′ gestation were examined.Results Complete cleft palate was diagnosed in 4 cases by ultrasonography, all of which were accompanied with complete cleft lip and alveolar process.Incomplete cleft palate were missed in 2 cases.Conclusions Complete cleft palate is accompanied mostly with cleft alveolar process and complete cleft lip, and cleft palate can be found out through cleft alveolar process.To those fetuses without cleft lip or with incomplete cleft lip,their palate cannot be explored by ultrasound,and their cleft palate cannot be displayed.

Objective: The experiment was designed to study the effects of compound Konjac glucomannan on hyperlipidemia for the purpose of improving the therapeutic efficacy. Method: First, hyperlipidemia rat models were established. Then the effects of compound Konjac glucomannan and Konjac glucomannan on blood lipids levels and hepatic tissue morphous of rats were detected. Result; The compound Konjac glucomannan could decrease LDL-C and ApoB levels of serum TC significantly, while notably increase HDL-C and ApoA-1 levels. The result also shows that compound Konjac glucomannan could obviously improve the TG metabolism and decrease blood glucose concentration. The morphologic observation indicates that both Konjac glucomannan and flavonids could protect liver tissues of rats. Conclusion; Compound Konjac glucomannan could improve regulative ability of lipids metabolism and decrease serum lipids levels.

Angiotensin-converting enzyme (ACE) gene is one of major candidate genes with genetic susceptibility to stroke. However, its correlation with stroke remains controversial. The relationship between gene polymorphism and stroke also cannot be determined. A specific branch in the ACE phylogenic tree may replace the insertion/deletion polymorphic site as a risk marker of stroke for association study.

Objective To investigate the treatment effect of minimally invasive excision in intrahepatic bile duct stones. Methods Ac-cording to different treatment methods, 280 patients with intrahepatic bile duct stones were divided into the treatment group (180 cases) and the control group(100 cases). The control group were given open hepatic lobectomy while the treatment group were given minimally invasive treatment of hepatic lobectomy by laparoscopy. Results All patients had successfully completed surgery and the stones were removed. Compared the operation time,intraoperative blood loss,and blood transfusion of the two groups,and there were no statistically significance (P>0. 05). The postoperative hospitalization,time of drainage tube remove, time of analgestic drug use in treatment group were obviously lower than those in control group,which had statistically significance (P<0. 05). The common postoperative complications of the two groups were bile leakage,wound infection,pleural effusion and subphrenic abscess,et al. The complication rate of treatment group was 2. 2%, while it was 10. 1% in the control group, which had significant difference (P<0. 05). All the patients were followed-up for 6 months, and there was no death in patients. Conclusion Intrahepatic bile duct stones in progress could be treated by hepatic resection surgery. Laparoscopic techniques could accelerate the recovery of patients and reduce the complication rate,and it would become a new treatment option.

BACKGROUND:A number of studies have been conducted on the prevention of enamel demineralization in orthodontic treatment, but no work has been carried out on the comparative studies addressing manual toothbrush, orthodontic fur V brush and interdental brush. OBJECTIVE:To compare the efficacy of manual toothbrush, orthodontic fur V brush and interdental brush on enamel decalcification during orthodontic treatment. METHODS:Adolescents, aged 12 to 17 years old, were randomly and averagely divided into three groups: manual toothbrush, orthodontic fur V brush, and interdental brush groups. Enamel decalcification index and augmenter of enamel decalcification index were examined and calculated by the same orthodontist before treatment and 1 year later. RESULTS AND CONCLUSION: There was no statistical difference in the enamel decalcification index among the three groups at the beginning (P > 0.05). After 1 year of treatment, the enamel decalcification index of each group was higher than that at the beginning (P < 0.05); the enamel decalcification index and augmenter of enamel decalcification index in the three groups were ranked as folows: orthodontic Fur V toothbrush group < manual toothbrush < interdental toothbrush group , and there was a statistical significant difference among the three groups (P < 0.05). Orthodontic fur V brush is proved to have advantages over manual toothbrush and interdental brush in the respect of controling enamel decalcification, and interdental brush has no good effect on preventing enamel demineralization while it is used alone.

Objective To compare laparoscopic appendectomy (LA) with open appendectomy (OA) in the treatment of appendicitis complicating gangrene,perforation and abscess in children.Methods This study included 614 consecutively admitted patients with acute complicated appendicitis undergoing laparoscopic (267 cases) or open (347 cases) appendectomy.Clinical outcomes were compared between the 2 groups in relation to operative time,length of hospital stay,postoperative complications and in hospital cost. Results There was no mortality.Conversion to open surgery was necessary in 7 patients in LA group.Laparoscopic appendectomy was associated with a shorter hospital stay (4.6 d vs.8.1 d,P =0.00),lower incidence of wound infection(5.3％ vs.12.8％,P =0.03),less bowel obstruction(5.0％vs.10.0％,P =0.04) and nosocomial infection (9.7％ vs.18.3％,P =0.04).Intra-abdominal abscess formation was significantly higher after laparoscopic surgery (4.1％ vs.1.1％,P =0.04 ).The cost of treatment and operative time were higher in the laparoscopic group than in open appendectomy,however,there was no statistically significant difference. Conclusions Laparoscopic technique is a safe and clinically beneficial operative procedure for complicated appendicitis in children with short hospital stay,early recovery,good cosmetic appearance,and low complication rate,except for a higher incidence of intraabdominal abscess.
