Objective To investigate the diagnostic accuracy of 13C urea breath test (13C-UBT)in the diagnosis of Helicobacter pylori (Hp) infection in patients with gastric remnant.Methods A total of 94 gastric remnant patients (gastric remnant group) and 100 non-gastric remnant patients (control group) received 13C-UBT.According to the course of the disease,the gastric remnant group were divided into group 1 (29 cases,≤5 years),group 2 (33 cases,6 to 10 years) and group 3 (32cases,＞10 years).Before surgery,the diagnosis of Hp infection was according to 13C-UBT and gastric mucosa tissue staining.After surgery,the diagnosis was according to gastric mucosa tissue staining.The applying value of 13C-UBT in gastric remnant patients was evaluated.The consistency of results between 13C-UBT and gastric mucosa tissue staining were evaluated by the Kappa test.Results In gastric remnant group,the Hp infection rate after surgery (37.2％) was obviously lower than that before operation (79.8％;x2 =35.058,P＜0.01) and that of control group (77.0％).After surgery,the Hp infection rate of patients with Billroth Ⅱ gastrectomy (24.4％) was lower than that of patients with Billroth Ⅰ gastrectomy (47.2％ ; x2 =5.133,P=0.023).Before surgery,the Hp infection rate of gastric remnant subgroups were similar (P＞0.05).With the extension of the postoperative course,the Hp infection rate gradually decreased in gastric remnant subgroups (group 1:58.6％,group 2:36.4％,group 3:18.8％; x2=7.839,P=0.021).Setting the cut-off point at 2.0‰ in the gastric remnant group and 3.5‰ in the control group,the accuracy rate of diagnosis was the highest (92.6％ and 96.0％).There was good consistency between the results of 13C-UBT and gastric mucosa tissue staining (Kappa =0.84,P＜0.01).Conclusion With suitable operation and standard,13C-UBT may be a easy,safe and effective assay applied in the gastric remnant patients.

OBJECTIVETo explore the pattern of abnormal skeletal development in girls with idiopathic precocious puberty (IPP) and the therapeutic effect of Chinese herbs for nourishing yin and purging fire (CH).

METHODSMeasurement of bone age, bone mineral content (BMC) and bone density (BD) were performed and levels of serum gla-protein (BGP), insulin-like growth factor 1 (IGF-1) and insulin-like growth factor binding protein 3 (IGFBP3) were determined in girls with IPP at various stages of pubertal development. Data were compared with those collected from matched girls, and the correlativity between various parameters and the extent of the disease were analyzed to explore the pattern. Thirty-eight girls out of them were treated with CH and the therapeutic effect was observed.

RESULTSThe bone age of the IPP girls was ahead of time obviously (P < 0.05), levels of BMC, BD and serum BGP, IGF-1 were significantly higher than the levels in the healthy girls of matched age (P < 0.05). And the degree of these changes were markedly positive correlated with the severity of disease (P < 0.05). After being remitted with CH treatment, the advanced bone age was apparently alleviated, and above-mentioned abnormal criteria were lowered significantly (P < 0.05).

CONCLUSIONThe skeletal development of the girls with IPP was accelerated and the skeletal maturity were ahead of time, the more serious the condition of disease, the more obvious the acceleration and the advanced bone age. CH could decelerate skeletal development and delay the skeletal maturity of IPP patients.

Objective To study the early diagnostic predictors and key follow-up parameters for girls with rapidly progressive central precocious puberty (RP-CPP). Methods A total of 260 girls with CPP participated in a prospective, nonrandomized, multi-center, nested case control study. After follow-up six months without any therapy, 114 girls were divided into RP-CPP (n=70) and slowly progressive CPP (SP-CPP) (n=44) groups. Results The basal serum LH and insulin-like growth factor Ⅰstandard deviation score (IGF-ⅠSDS) were the important risk factors of RP-CPP (OR 4.04, 1.578), especially the former. The receiver operating characteristic (ROC) curve revealed that the areas under the ROC curve of basal LH and IGF-ⅠSDS were 0.83 and 0.807, respectively. The levels of basal LH and IGF-ⅠSDS were at 0.52 mIU/ml and 0.35 respectively for the accuracy diagnosis of RP-CPP with the maximum Youden indexs. After follow-up for six months, the change levels of height, breast stages, bone age/chronological age ratio, serum LH, uterine and ovarian volume in RP-CPP group were significantly higher than those in SP-CPP group (all P<0.05). Conclusions The level of basal serum LH and IGF-ⅠSDS may be used as the risk predictors for early diagnosis for girls with RP-CPP. The change levels of basal LH, progress rates of gonad and sex character, height, and impaired growth potential seem to be the key follow-up parameters for CPP progress.

OBJECTIVETo compare the curative effects of primary osteoporosis treated with heat-sensitive point moxibustion and Gaitianli (Oyster Shell and Calcium Carbonate Chewable) tablets for oral administration and explore the treatment mechanism.

METHODSSixty cases of primary osteoporosis were randomly divided into a heat-sensitive point moxibustion group (moxibustion group) and a Gaitianli tablets group (medication group), 30 cases in each group. In the moxibustion group, the heat sensitized points were searched around Zusanli (ST 36), Pishu (BL 20), Shenshu (BL 23) and Mingmen (GV 4) and treated by heat-sensitive point moxibustion; in medication group, Gaitianli tablets were taken by oral administration, 3 pills for once and 3 times a day. The curative effects, bone mineral density (BMD), alkaline phosphatase (S-AKP) and urinary calcium to creatinine ratio (U-Ca/Cr) in both groups were observed before and after treatment.

RESULTSThe total effective rate was 86.7% (26/30) in moxibustion group, superior to that of 76.7% (23/30) in medication group (P < 0.05). After treatment, the BMD of lumbar vertebrae (L2-L4) mean was improved (P < 0.05), and the S-AKP and U-Ca/Cr were reduced (all P < 0.05); in medi cation group, the indexes above were no obvious changes (all P > 0.05).

CONCLUSIONThe therapeutic effect of primary osteoporosis treated with heat-sensitive point moxibustion is superior to that with Gaitianli tablets for oral administration. The mechanism is restraining bone resorption, increasing bone strength, keeping balance of bone metabolism, in order to increase bone mineral density and improve the clinical symptoms.

AIMTo provide experimental basis for clinical use of cryopreserved dendritic cells (DCs) by investigating the biological properties of cryopreserved DCs derived from cord blood.

METHODSThe biological discrepancies between unfrozen DCs (UFDC) derived from unfrozen cord blood (UFCB) and DCs from cryopreserved cord blood (CPCB) or cryopreserved DCs (CPDCs) were explored by morphological observation and immunophenotype analysis. Moreover, the stimulating index (SI) in mixed lymphocyte culture and cytotoxic eliminating rate (ER) were measured by MTT.

RESULTSThe TBR of CPCB and CPDCs were 95.8% and 88.7% respectively. Compared to UFCB, CPCB differentiated toward DCs in a delayed and decreased mode, displayed lower expression of CD1a, CD83 and HLA-DR, and had reduced SI and ER. Similarly, the CPDCs became adherent DCs later and grew less in number than UFDCs. After culture, the expression of CD1a, CD83 and HLA-DR as well as SI and ER were lower in CPDCs than those in UFDCs.

CONCLUSIONThough the biological properties of CPCB and CPDCs were injured after cryopreservation, they still had relatively complete basic function. Their recoveries rate were > 85%.

OBJECTIVETo explore whether fractional anisotropy (FA) value could be taken as a quantitative indicator for tracing and reexamining amyotrophic lateral sclerosis (ALS), and to analyze the correlation between FA value and integrative medical treatment.

METHODSTotally 18 ALS patients were recruited in this study. All patients received diffusion tensor imaging (DTI) using 3. OT (Propeller HD) MRI twice. Six regions of interest (ROI) were selected to measure FA values. Survival analyses were performed in 11 cases of end point events.

RESULTS(1) Three ROI (cerebral peduncle, posterior limb of internal capsule, and corona radiata) all indicated that FA value was the highest in patients with mild health status scale of amyotrophic lateral sclerosis (ALS/HSS). (2) There was statistical difference in the means of FA values in cerebral peduncle, posterior limb of internal capsule, and corona radiata of 18 cases between initial examination and reexamination (P < 0.01). (3) Kaplan-Meier survival curve showed the survival rate of ALS patients decreased as time went by, with the median survival time of 48 months.

CONCLUSIONSFA value was inversely proportional to the severity of ALS, the more severe, the lower FA values. FA value was an objective indicator for assessing the severity of ALS. ALS is an incurable disease till now. Integrative medical treatment might become one direction for ALS patients.

Excessive tortuosity is a notable cause of failed endovascular thrombectomy for acute large-vessel occlusion stroke. Transcervical access (TCA) is a commonly proposed solution for overcoming this difficulty. However, the large-bore catheter usually used in TCA increases the risk of serious local complications. This paper presents a modified technique for TCA that uses a pull-through buddy wire (PTBW) to track a large-bore femoral guiding sheath (GS) into the carotid artery via a small carotid puncture site. The carotid puncture site can be easily managed through gentle manual compression. Two illustrative cases using this technique to deal with a large aortic arch and tortuous left common carotid artery are reported. In both cases, recanalization was achieved after successful GS placement. Using a PTBW is feasible in TCA.
