Hilar cholangiocarcinoma is a common bile duct cancer.The radical resection rate of end-stage malignancies reported in literature is about 20％.Half of the patients have lost the chance of operation at the time of care,while the average survival time in the patients who can not be operated is about six months.Therefore,for most patients,looking for a palliative treatment which can prolong the survival time is particularly important.From June 2013 to June 2014,our hospital applied iodine-125 brachytherapy,to treat 7 patients with unresectable hilar cholangio carcinoma.All the patients are still alive,the average survival time of 7 patients is 5.2 months up to now,with median survival time being 7.8 months,and longest survival time being 12 months.With good outcomes,few complications,as well as significantly prolonged survival time,iodine125 brachytherapy is regarded with broad clinical applications.

OBJECTIVETo explore significance of preoperative color Doppler flow imaging (CDFI) for screening deep vein thrombosis in upper limbs fracture.

METHODSFrom January 2009 to December 2011, 1200 patients with upper limb fracture caused by trauma were respectively analyzed. There were 833 males and 367 females,ranging from 20 to 78 (mean 41.94 +/- 15.41) years. All patients had swelling and pain in injured limbs when enrolled. CDFI was used to examine upper limbs vein at 3 to 10 d after improvement of swelling, 1 day before reduction. Relationship among occurrence of thrombosis, gender, age and fracture sites were analyzed. Patients with DVT were analyzed with respective study to decide whether combined with diabetes, hypertension and hyperlipidemia.

RESULTSAll patients were checked by CDFI,which confirmed 9 cases with DVT. The rate of thrombosis was 0.75%, women than men (P < 0.01). The risk of blood clots occurred over 30 years, and the occurrence of thrombosis in humerus fracture was higher than radius ulnar fracture. One of 9 patients combined with hypertension and hyperlipidemia, 1 case combined with diabetes, and 7 cases with no complication.

CONCLUSIONUpper trauma fracture may occur deep vein thrombosis; CDFI should be used to check DVT in qualified hospital,which can maintain medical safety,decrease occurrence of medical disputes, and ganrantee patient's safety.

OBJECTIVEIn order to improve the irrigation for Panax notginseng growing seedlings, different mulching ways were carried out to investigate the effects of double mulching.

METHODField experiment was applied to study soil moisture, soil temperature and bulk density of different mulching ways while the germination rate and seedlings growth also were investigated.

RESULTCompared with the traditional single mulching with pine leaves or straw, double mulching using plastic film combined with pine leaves or straw could reduce 2/3 volumes of irrigation at the early seedling time Double mulching treatments didn't need to irrigate for 40 days from seeding to germination, and kept soil moisture and temperature steady at whole seedling time about 30% and 9.0-16.6 degrees C, respectively. The steady soil moisture and temperature benefited to resist late spring cold and germinate earlier while kept germination regularly, higher rate and seedlings quality. In contrast, single mulching using pine leaves or straw had poor soil moisture and temperature preserving, needed to irrigate every 12-day, meanwhile dropped the germination and booming time 14 days and 24-26 days, respectively, reduced germination rate about 11.3%-8.7%. However, single pine leaves mulching was better than straw mulching. In addition, though better effects of soil moisture and temperature preserving as well as earlier and higher rate of germination with single plastic films mulching had, some disadvantages had also been observed, such as daily soil temperature changed greatly, seedling bed soil hardened easily, more moss and weeds resulted difficulty in later management.

CONCLUSIONTo the purpose of saving water and labor as well as getting higher germination rate and seedlings quality, double mulching using plastic films combined pine leaves at the early time and single mulching removing plastic films at the later time is suggested to apply in the growing seedlings of P. notoginseng.

OBJECTIVETo Explore the significance of preoperative screening of deep vein thrombosis (DVT) on the prevention from pulmonary embolism (PE) with color Doppler flow imaging (CDFI) in patients of lower limb fractures.

METHODSA total of 2 000 patients with lower limb fractures were retrospectively analyzed from January to September in 2010. All the patients were scheduled to be operated. There were 1 140 males and 860 females, ranging in age from 18 to 94 years, with a mean of (54.78 +/- 21.45) years. Swollen limbs could be observed in all patients when admitted and traditional Chinese medicine therapies were given by both internal and external administrations. Selective internal or external fixations were scheduled 3 to 14 days after injured and the swell relieved. CDFI screenings for DVT were applied to all the patients one day before operations and clinical data, such as gender, age, fracture site and course of diseases, were analyzed.

RESULTSOf all the 2 000 patients, 128 patients had lower limbs DVTs (6.4%). Among all the DVT patients, 52 patients had DVT within vena iliacas or femoral veins,20 patients had DVT within popliteal veins or vena crualis, 56 patients had DVT within small muscular veins of legs. Thrombolytic therapies or inferior vena cava filters were taken to 72 patients with DVTs proximal to vena cruralises and thrombi disappeared in 20 cases. Inferior vena cava filters were placed in 17 patients. There were 28 patients with either failed thrombolytic or no filters placement. All above 65 patients were treated with fracture reduction, and other 7 patients were treated with conservative methods. Of all the operated patients, one patient had PE during operation and recovered after immediately rescue. Among 56 patients with DVT within small muscular veins of legs, 51 patients were treated with reduction without other special treatment, and other 5 patients were treated with conservative methods. There was no relationship between DVT occurrence and gender. The youngest sufferer was 22 years old. DVT occurrences of patients over 41 years old were significantly higher than that of patients under 40 years old. Higher occurrences were also observed in patients with multiple fractures, fracture of femurs compared with those with tibia or fibula fractures. DVT was found as early as 3 days after injury in one case. The longer the time from injuries to operations, the higher the occurrences of DVTs.

CONCLUSIONRoutine CDFI screenings should be applied to traumatic fractured patients before operations no matter whether there are DVTs existing or not. That is very important for the prevention of fatal PE during both anesthesias and operations.

The aim of this Post-Marketing Surveillance study was to assess efficacy,safety and acceptance of acarbose treatment in Chinese type 2 diabetic patients under day-to-day practice conditions.A total of 2 480 patients were enrolled by 231 physicians throughout China into an open,prospective,uncontrolled,non- randomised,multi-centre study.Main efficacy parameters were the changes in fasting and postprandial blood glucose concentrations as well as in HbA-(1C) levels after acarbose treatment.The majority of patients had been previously treated with other oral anti-diabetic medication or insulin and received concomitant anti-diabetics during the mean observation period of 13.5 weeks.Most patients started on a daily acarbose dose of 50 mg t.i.d. Acarbose treatment reduced fasting blood glucose concentrations by 56.1 mg/dl ( 18 mg/dl glucose = 1 mmol/L glucose) and 2h-postprandial values by 111.3 mg/dl over the study period.HbA-(1C) decreased by 1.9% and body weight by 0.9 kg.76 acarbose-relatod adverse events occurred;two patients experienced serious adverse events. The attending physicians assessed treatment efficacy as“very good”or“good”for 90.1% of the patients, tolcrability for 89.1% and acarbose acceptance for 87.1% of the patients.Acarbose is efficacious,safe and well accepted by Chinese type 2 diabetic patients under day-to-day routine conditions,both as anti-diabetic mono- therapy and in combination with other anti-dlabetic drugs.

Both the incidence and mortality of nasopharyngeal carcinoma(NPC) have decreased in Hong Kong and Taiwan but not in mainland China. The goal of this study was to analyze trends in NPC patient survival between 1976 and 2005 in Sihui, an area of mainland China with a population at high risk for NPC. A total of 1,761 patients diagnosed with NPC between 1976 and 2005 according to the records of Sihui Cancer Registry were followed to the end of 2006. We determined their observed and relative survival rates and used Cox proportional hazards regression analysis to predict prognosis. Our results showed that the 5-year and 10-year observed survival rates of NPC patients in Sihui were 50.5% and 36.9%, respectively, and the median survival time was 5.1 years. The 5-year observed survival rate of NPC patients diagnosed after 2000 was 69.8%, significantly higher than that of patients diagnosed between 1976 and 1985 (42.5%; P < 0.001, relative risk = 0.28). Similarly, the 5-year relative survival rate was 84.8% between 2000 and 2005 but 51.8% between 1976 and 1985. Besides date of diagnosis, other prognostic factors included patient sex and age and NPC clinical stage and histologic type. The relative risks of death from NPC were 0.76 [95% confidence interval (CI): 0.65-0.90] for female comparing to male and 1.28 (95% CI: 1.00-1.64) for WHO type I comparing to WHO types II and III. For the eldest age group and the latest clinical stage group, the relative risks were 2.22 (95% CI: 1.73-2.84) and 3.41 (95% CI: 2.34-4.49), respectively. Our results indicate that the survival of NPC patients in Sihui has significantly increased in recent years and this increase is not influenced by patient's sex, age, histologic type, and clinical stage. A reduction in mortality rate is expected in coming years.

OBJECTIVETo assess the value of compound anesthesia of transcutaneous electrical point stimulation and Remifentanil and the efficacy of this method on postoperative acute pain.

METHODSSixty cases with vertebral lamina internal fixation decompression operation were selected and randomly divided into 2 groups, an observation group and a control group, 30 cases in each group. The patients in the observation group received compound anesthesia of transcutaneous electrical point stimulation at Hegu (LI 4), Laogong (PC 8), Neiguan (PC 6) and Waiguan (TE 5) 30 min before anesthesia induction with HANS stimulator and then Remifentanil anesthesia. During the operation, the stimulation was lasted for 30 min and ceased for 30 min until the end of operation. The patients in the control group received simple Remifentanil anesthesia. The dosage of the narcotic, changes of both blood pressure and heart rate during operation, before and after extubation and the pain degree, etc. were investigated in the two groups.

RESULTS(1) The dosage of Isoflurane, (0.52 +/- 0.33)vol%, in the observation group was significantly lower than (1.12 +/- 0.18) vol% in the control group (P < 0.01). (2) Both blood pressure and heart rate during operation, before and after extubation in the observation group were lower than those before operation (P < 0.01), and both the blood pressure and heart rate during operation in the control group were lower than those before operation (P < 0.01). The blood pressure after extubation in the observation group was significantly lower than that of the control group (P < 0.01), and the heart rate before and after extubation in the observation group was significantly lower than that of the control group (P < 0.01). (3) The time of extubation and palinesthesia in the observation group were significantly shorter than those in the control group (P < 0.01). (4) In the observation group, the VAS scores after palinesthesia in 26 cases were < 4, and in 4 cases were > or = 5, while in the control group, the scores in 4 cases were < 4 and in 20 cases > or = 5, with a significant difference between the two groups (P < 0.01).

CONCLUSIONCompound anesthesia of transcutaneous electrical point stimulation and Remifentanil can reduce the dosage of narcotics, shorten the time of palinesthesia and effectively prevent and treat acute pain after Remifentanil anesthesia.

OBJECTIVETo investigate the effects of lead exposure at different levels in utero on the teeth eruption and enamel development of rat offsprings.

METHODS27 pregnant SD rats were divided into three groups randomly: high level lead group (HLG), low level lead group (LLG) and control group with nine rats in each group. The three groups from the gestation day to the end of the gestation were given either deionized water in control group or deionized water containing 200 mg/L Pb2+ as lead acetate through drinking method in high level lead experimental group and 50 mg/L Pb2+ as lead acetate through drinking method in low level lead experimental group. The incisors of newborn rats were marked at the level of the gingival papilla on the 26th day after birth. On the 36th day, the incisors of newborn rats were marked again at the same level. Then the rat offsprings were killed and their blood was collected for lead analysis. The mandible incisors of rat offspring were separated and the content of Pb in incisors was determined by using a graphite furnace atomic absorption spectrometric method. The teeth of rat offspring were observed and the distance between two marks were measured by means of stereomicroscope. The ratio of calcium to phosphate of enamel of rat offspring was compared by electron probe microanalyses.

RESULTSThe level of blood lead in 200 mg/L, 50 mg/L treated rat offspring groups was higher than that in control group. The tooth lead of 200 mg/L, 50 mg/L treated rat offspring groups [(77.3 +/- 6.3), (27.8 +/- 4.5) microg/g] were higher than the control [(6.6 +/- 0.8) microg/g, P < 0.01]. Compared with the control group, the teeth of lead exposure experimental groups were smaller and severity of attrition was obvious and pulpal perforations were often observed. These appearances was more distinct in rats of high level lead experimental group. The incisors of lead-treated rat offspring erupted [(0.25 +/- 0.08), (0.30 +/- 0.09) mm/d] more slowly than control ones [(0.39 +/- 0.09) mm/d, P < 0.01]. The ratio of calcium to phosphate (Ca/P) decreased with the increase of lead exposure. It was found that Ca/P in lead exposure experimental groups (1.68 +/- 0.54), (1.37 +/- 0.47) was significantly lower than that in the control group (2.14 +/- 0.33).

CONCLUSIONLead exposure in utero affects the normal eruption of teeth and enamel formation and the degree was related with the lead exposure level.

Objective: The status of masked obesity in female college students and the related factors were investigated to provide a theoretical reference for instructing the physical health education of female college students and improving their physical exercises. Methods: Body composition tests were performed on 2 975 female college students, selected from 3 colleges in North China by using cluster sampling method during October to December in 2018, and their basic information and lifestyle were investigated using questionnaires. Results: The incidence of masked obesity among female college students was 33.18%, of which 2.53% came from low-weight people. The difference in the incidence of masked obesity among female college students with different take-out frequencies was statistically significant (χ2=21.98, P<0.01). Compared with those who never take takeaway, people who take takeaway every day have an increased risk of masked obesity (OR=1.49, 95%CI=0.76-2.91). The difference in the incidence of masked obesity with the frequency of eating midnight snack was statistically significant (χ2=20.80, P<0.05). The difference in the incidence of masked obesity among female college students with different exercise time was statistically significant (χ2=18.49, P<0.01). Compared with exercise time above 60 min/d, female college students who are not exercising have an increased risk of masked obesity (OR=3.20, 95%CI=1.63-6.30). The difference in the incidence of masked obesity among female college students with different weight satisfaction was statistically significant (χ2=217.54, P<0.01). Compared with female college students who were satisfied with weight, female college students who were not satisfied with weight had an increased risk of masked obesity (OR=3.47, 95%CI=1.91-6.31). The difference in the incidence of masked obesity in different weightdown plans is statistically significant (χ2=186.40, P<0.01). Those who want to lose weight have a higher risk of developing masked obesity than those who want to gain weight (OR=18.11, 95%CI=5.54-50.13). Conclusion Female college students who drink a small amount of water, eat takeaways often, eat midnight snacks, do not exercise, and are not satisfied with their weight are more likely to develop masked obesity.
