OBJECTIVETo observe the impact of inducing the formation of the post-moxibustion sore on the efficacy of bronchial asthma treated with scarring moxibustion.

METHODSThree hundred and seventy-two cases diag nosed definitely as bronchial asthma at remission stage were randomly divided into a modified nursing group (248 cases) and a conventional nursing group (124 cases). The scarring moxibustion was applied at Dazhui (GV 14), Feishu (BL 13), Danzhong (CV 17) and Tiantu (CV 22) in either group. The direct moxibustion with moxa cone was adopted. In modified nursing group, 0.5% Iodine was used for the sterilization at moxa abscess. The herbal plaster was cut into an inverted triangle and compressed on the wound. After suppuration, the fester was not cleaned in each dressing change. Additionally, the patients were advised to have high-protein diets after moxibus tion till abscess dropped. In conventional nursing group, 0.5% Iodine was used for the sterilization at moxa abscess. The herbal plaster was cut into a round shape that could cover completely the moxa wound. After suppuration, in each dressing change, the wound was cleaned and sterilized. Additionally, the patients were advised to avoid any stimulating food after moxibustion till abscess dropped. The clinical efficacy, the change of C3 content in blood serum and the clinical symptom score were observed in two groups.

RESULTSThe total effective rate was 93.5% (232/248) in modified nursing group, which was better than 79.0% (98/124) in conventional nursing group (P < 0.01). C3 content increased apparently after treatment as compared with that before treatment in either group (both P < 0.01), but C3 level increased much more apparently in modified nursing group as compared with that in conventional nursing group (P < 0.01). The clinical symptom score reduced apparently after treatment in either group (both P < 0.01), but that reduced much more apparently in modified nursing group as compared with that in conventional nursing group (P < 0.01).

CONCLUSIONIn the treatment of bronchial asthma with scarring moxibustion, to induce the formation of the post-moxibustion sore achieves the better clinical efficacy as compared with conventional nursing.

OBJECTIVETo study the mechanism of Tongjiang granule on treating GERD.

METHODThe rats in the model group received steel wire ring-cardiamyopexy. A steel wire ring was fixed firmly on cardia. The rats in the control group underwent the cardia-plasty plus pylori ligation plus stomach-empty intestine Roux-en-Y anastomosis. The rats were divided into six groups after operations at random, which were fed up respectively with Tongjiang granule of different dosage and perpulsid. No treatment groups were taken as control.

RESULTThe experiment showed that Tongjiang granule could lighten or cure RE in the pathology, decrease the hydrochloric acid in gastric juice, in the meantime, increase the motilin in the animal blood. This study indicated that the effect of Tongjiang granule group from experimental research was better than that of the control group (perpulsid).

CONCLUSIONThe effects of Tongjiang granule on treating GERD can be achieved by decreasing the hydrochloric acid in gastric juice, increasing the motilin in blood and promoting the gastric impetus in the animal experiment.

The study was aimed to investigate the potential immunotherapeutical values of umbilical cord tissue-derived mesenchymal stem cells (UC-MSC) on patients with chronic idiopathic thrombocytopenic purpura (ITP). UC-MSC was cocultured in vitro with splenocytes isolated from ITP patients who experienced splenectomy. The level of IgG antiplatelet antibody (PAIgG) was determined by a competitive micro-enzyme-linked immunosorbent assay (ELISA) method. The proliferation of platelet-reactive CD4+ T lymphocytes was also measured in the presence of UC-MSCs. The results showed that UC-MSCs could stimulate the spontaneous secretion of PAIgG in supernatants; In the platelet-inducing condition, UC-MSC inhibited the production of PAIgG at a low ratio of 1 UC-MSC to 100 splenocytes, but promoted at a high proportion of 1 UC-MSC to 10 splenocytes. Moreover, UC-MSC exerted a suppressive effect on proliferation of platelet-reactive T helper cells in a dose-dependent manner. It is concluded that the UC-MSCs can regulate secretion of antiplatelet antibodies in vitro. Its concrete regulation mechanism and potential immunotherapeutical value are need to further study.

OBJECTIVETo identify the active material of anti-hepatic fibrosis from Amydae Carapax.

METHODSMembrane separation technology was adopted to screen active fraction in Amydae Carapax, and the active components were isolated from the active fraction using gel chromatography and high performance liquid chromatography. The purified active components in Amydae Carapax were further analyzed using 4700 series time-of-flight mass spectrometer.

RESULTSProteins and peptides of Amydae Carapax with molecular weight less than 6000 were proved to have biological activity. 8 components (Bj1-Bj8) were isolated from the active fraction. Bj4, Bj6 and Bj7 were screened as active components. Bj7 was further purified, resulting in 7 components (Bj701-Bj707). Bj704 and Bj707 showed significant biological activity. Mass spectrometry showed three molecular ion peaks with highest abundance, i.e. m/e 526, 542 and 572, i.e. m/e 526, 542 and 572, in Bj707 -A The amino acid sequences of above three peptide compounds were NDDY (Asn-Asp-Asp-Tyr), NPNPT (Asn-Pro-Asn-Pro-Thr), and HGRFG (His-Gly-Arg-Phe-Gly), respectively. And M572 was the most abandunt components.

CONCLUSIONThree active peptide compounds of anti-hepatic fibrosis of Amydae Carapax were identified.

Overexpression of human epidermal growth factor receptor-2 (HER2) in metastatic breast cancer (MBC) is associated with poor prognosis. This single-arm open-label trial (EGF109491; NCT00508274) was designed to confirm the efficacy and safety of lapatinib in combination with capecitabine in 52 heavily pretreated Chinese patients with HER2-positive MBC. The primary endpoint was clinical benefit rate (CBR). Secondary endpoints included progression-free survival (PFS), time to response (TTR), duration of response (DoR), central nervous system (CNS) as first site of relapse, and safety. The results showed that there were 23 patients with partial responses and 7 patients with stable disease, resulting in a CBR of 57.7%. The median PFS was 6.34 months (95% confidence interval, 4.93-9.82 months). The median TTR and DoR were 4.07 months (range, 0.03-14.78 months) and 6.93 months (range, 1.45-9.72 months), respectively. Thirteen (25.0%) patients had new lesions as disease progression. Among them, 2 (3.8%) patients had CNS disease reported as the first relapse. The most common toxicities were palmar-plantar erythrodysesthesia (59.6%), diarrhea (48.1%), rash (48.1%), hyperbilirubinemia (34.6%), and fatigue (30.8%). Exploratory analyses of oncogenic mutations of PIK3CA suggested that of 38 patients providing a tumor sample, baseline PIK3CA mutation status was not associated with CBR (P = 0.639) or PFS (P = 0.989). These data confirm that the lapatinib plus capecitabine combination is an effective and well-tolerated treatment option for Chinese women with heavily pretreated MBC, irrespective of PIK3CA status.

OBJECTIVETo discuss the use of free jejunal flap in reconstruction for circumferential defect after tumor resection of hypopharyngeal and cervical esophageal cancer.

METHODSRetrospective review of 51 patients who underwent circumferential pharyngoesophageal reconstruction with free jejunal flap after tumor ablation.

RESULTSIn 51 patients, 5 had flap failure and the flap success rate was 90% (46/51). Forty-five patients had oral intake after operation excluding one who had anastomosis stenosis and 5 who had flap failure. The 1-year and 3-year survival rate was 62% and 48% respectively. Positive surgical marginal status and external invasion including thyroid gland, carotid artery, skin and pre-vertebral area were indicators for bad prognosis. Except 5 patients who had flap failure, one of which died from mediastinal infection, no other severe complications occurred.

CONCLUSIONSPatients reconstructed with free jejunal flap after resection of hypopharyngeal and cervical esophageal cancer had low mortality and few complications. Those without positive surgical margin and external invasion including thyroid gland, carotid artery, skin and pre-vertebral area had higher survival rate. Most of them had good quality of life. The choice of free jejunal flap for reconstruction of hypopharyngoesophageal defect was appropriate in selected patients who had guarantee of negative surgical margin and no external invasion.

OBJECTIVETo describe the epidemiology of neural tube defects (NTDs) in high- and low-prevalence areas of China.

METHODSBirth defects surveillance data, collected from 1992 through 1994 was analyzed. These data were collected as part of the Sino-American cooperative project on NTDs prevention. We classified NTDs as anencephaly, encephalocele, high-level and low-level spina bifida (SB) according to location of the lesion (high vs low) and whether the defect was isolated or occurred in association with other birth defects. Rates were compared in the high-prevalence (North) region and the low-prevalence (South) region, after adjusted for classification, urban and rural, season and sex, and calculated the adjusted rate of NTDs.

RESULTSAmong seven hundred and eighty-four NTDs cases in 326 874 recorded births (include in livebirth, stillbirth and fetal death with a gestational age of at least 20 weeks), the overall NTDs prevalence in the North was 5.57/1,000 births, and in the South was 0.88/1 000. There were also significant differences in the prevalence of anencephaly, encephalocele, high-level and low-level SB between North (0.97, 0.49, 2.75 and 1.11/1,000 birth) and South (0.36, 0.15, 0.21 and 0.14/1,000 birth) (P < 0.01), with adjusted prevalences in the North 3 - 7 times higher than those in the South. There were significant difference between urban (2.04) and rural areas (6.57/1,000 birth) in the North (P < 0.01), urban (0.52) and rural areas (0.95/1,000 birth) in the South (P < 0.05). Adjusted prevalence rates in the rural were 3 - 4 times higher than those of urban in the North and 1.6 - 1.9 times higher than in the South; The seasonal rate of high-level SB increased between September and November in the North (3.44/1,000 birth), while the seasonal rate of anencephaly decreased between September and November (0.18/1,000 birth) in the South. However there were no seasonal changes in other classified NTDs both in the South and North.

CONCLUSIONSThe birth prevalence of NTDs in the North of China was the highest in the world. There were significant differences between the North and the South, urban and rural. There was seasonal change in high-level SB in the North, which was in accordance to the phenotype of NTDs. It was suggested that there might exist etiological heterogeneity among anecephalus, low- and high-level SB.
