OBJECTIVETo compare the effect of citric acid stimulation on salivary alpha-amylase (sAA), total protein (TP), salivary flow rate, and pH value between Pi deficiency (PD) children and healthy children, thereby providing evidence for Pi controlling saliva theory.

METHODSTwenty PD children were recruited, and 29 healthy children were also recruited at the same time. Saliva samples from all subjects were collected before and after citric acid stimulation. The sAA activity and amount, TP contents, salivary flow rate, and pH value were determined and compared.

RESULTS(1) Citric acid stimulation was able to significantly increase salivary flow rate, pH value, sAA activities, sAA specific activity and sAA amount (including glycosylated and non-glycosylated sAA amount) in healthy children (P<0.05), while it could markedly increase salivary flow rate, pH value, and glycosylated sAA levels in PD children (P<0.05); (2) Although there was no statistical difference in determined salivary indices between the two groups (P>0.05), salivary indices except salivary flow rate and glycosylated sAA levels decreased more in PD children. There was statistical difference in sAA activity ratio, sAA specific activity ratio, and the ratio of glycosylated sAA levels between PD children and healthy children (P<0.05).

CONCLUSIONPD children had decreased response to citric acid stimulation.

BackgroundIt has been proved that as a chemokine,interferon-inducible protein-10(IP-10)can regulate the immuno-inflammatory reaction.Some new researches showed that IP-10 also played role in regulating the neovascular vessel formation.Corneal neovascularization (CNV) is associated with multiple cellular factors,but its mechanism is below clear.Objective The present study was to address the roles of exogenous mouse IP-10 in alkali burn-induced CNV.Methods Eighty-two SPF BALB/c mice were used in this experiment and grouped according to random number table.The corneal alkali burn models were established by putting the filter paper with 1 mol/L NaOH at the central corneas of the left eyes for 40 seconds.10 mg/L IP-10 was topically administered from the first day or 14 days after modeling in the early intervene group( 10 eyes)or middle-late intervene group(5 eyes).CNV area was measured as a percentage of whole cornea.0.2％ sodium hyaluronate(HA) as vehicle was utilized in the model control group.Angiogenic factor expression in corneal tissue in the early intervene group was quantified by reverse transcriptase polymerase chain reaction (RT-PCR)and compared with model control group.All animal experiments were performed in accordance with the Association for Research in Vision and Ophthalmology Statement for the Use of Animals in Ophthalmic and Vision Research and complied with the standards of Guidelines for the Care and Use of Laboratory Animals of Soochow University. ResultsThe CNV percentage was(88.67±10.22) ％ in the model control mice,showing a significant increase in comparison with that of IP-10 early intervene group (70.06±12.21)％ (t=3.77,P=0.00).In 21 days after corneal alkali burn,the CNV percentage was(87.33±13.47)％ in the model control mice,and that of the IP-10 middle-late intervene group was ( 86.56± 12.47 ) ％ without significant difference between them ( t =1.26,P＞0.05 ).Two days or four days after IP-10 early intervene,the expressions of chemokine receptor type 3 ( CXCR3 ) in corneal tissue were significant higher than model control group( t =3.13,3.07,P＜0.05 ),but the expressions of vascular endothelial growth factor (VEGF) in cornea were lowed ( t =5.99,6.27,P＜0.01),and so were transforming growth factor-β1 (TGF-β1) (t =8.50,P＜0.01;t =4.53,P＜0.05).Conclusions The early topical administration of the exogenous mouse IP-10 can inhibit CNV by up-regulating CXCR3 expression and down-regulating VEGF and TGF-β1 expression in cornea.However,middle-later usage of the IP-10 is uneffective.

OBJECTIVETo observe the effects of blood activating wind dissipating acupuncture (BAWDA) on blood pressure (BP) of prehypertension (PHT) patients.

METHODSTotally 60 PHT patients were assigned to the control group and the acupuncture group according to random digit table, 30 in each group. All patients were intervened by life style. BAWDA was additionally performed in patients in the acupuncture group for 6 weeks (30 times). The improvement of BP after intervened by acupuncture was observed. BP success rates and the proportion of PHT progressing to hypertension (HT) were also observed after 6-week intervention of acupuncture and at 1-year follow-up.

RESULTSSystolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased after 6-week intervention in the acupuncture. The BP control rate was 56.7% (17/30 cases) in the acupuncture group vs.10.0% (3/30 cases) in the control group with statistical difference (chi2 = 14.70, P < 0.01). At 1-year follow-up BP success rate was 36.7% (11/30 cases) in the acupuncture group, remarkably higher than that of the control group [13.3%, (4/30 cases)] (chi2 = 4.36, P < 0.05).

CONCLUSIONSBAWDA showed BP regulating roles in a gradually stable decreasing tendency. It also could elevate BP success rate of PHT, and reduce the risk of PHT progressing to HT.

The purpose of this study was to investigate the growth characteristics and the expression level of integrin mRNA of the cultured bone marrow mesenchymal stem cells (BMMSCs) from patients with chronic myeloid leukemia (CML) in myeloid crisis (MC), and explore the role of BMMSCs in pathogenesis of CML. Five CML patients were enrolled in experimental group, five healthy persons were used as control. BMMSCs were cultured in vitro. The morphology of BMMSCs was observed every day and the growth curve were portrayed, and the ability of cell proliferation were detected according to the daily results of cell counting. Total RNA was extracted from third and fourth passages of BMMSCs, The expression of integrins mRNA of BMMSCs were measured by real-time PCR. The results showed that the BMMSCs of experimental and control groups had no difference in growth characterisctics, but the expression of integrins mRNA of the BMMSCs was higher in CML patients than in normal control group (p < 0.05). It is concluded that the abnormally high expression of integrins of BMMSC from the CML patients take part in pathogenesis of CML.

OBJECTIVETo compare a side-to-side esophagogastric anastomosis with conventional hand-sewn or stapled esophagogastrostomy for prevention of anastomotic stricture by randomized clinical trial.

METHODSBetween November 2007 and September 2008, 160 patients with esophageal carcinoma or gastric cardia cancer were consecutively admitted and underwent surgical treatment. After excluding 5 patients (2 refused to participate in and 3 did not meet inclusion criteria), the remaining 155 patients were completely randomized to receive either a side-to-side esophagogastric anastomosis (SS group), or the conventional hand-sewn (HS group), or a circular stapled (CS group) anastomosis, after the removal of esophageal tumor. The primary outcome measured the incidence of anastomotic stricture at 3 months after the operation (defined as the diameter of the anastomotic orifice

RESULTSThere was 1 operative death (in HS group) and 1 simple exploration (in SS group). The anastomotic leakage was observed in 4 patients (2 cervical and 1 intrathoracic leaks in HS group, and 1 intrathoracic leak in CS group). The follow-up rate was 96.1% (1 patient in SS group, 3 in HS group, and 2 in CS group were lost). Finally 45 patients in SS group, 52 in HS group, and 47 in CS group were included in the analysis. The 3 groups were preoperative similar. The anastomotic stricture rate was 0% (0/45) in SS group, 9.6% (5/52) in HS group, and 19.1% (9/47) in CS group, respectively (Fisher exact probability test, P = 0.005). The reflux/regurgitation score among 3 groups was similar (chi(2) = 1.681, P = 0.432).

CONCLUSIONThe side-to-side esophagogastric anastomosis could prevent stricture formation, without increasing gastroesophageal reflux.

The study aimed to explore the changes of the immunocyte quantities and cytotoxicity in bone marrow, and how many hematopoietic progenitor cells retained after the bone marrow cells were activated by different combinations of various cytokines. Bone marrow cells were divided into four groups and were cultured in vitro: (1) Control: no cytokines were added. (2) IL-2 group: bone marrow cells were activated by IL-2. (3) CD3-AK group: bone marrow cells were activated by IL-2 and CD3-McAb. (4) CIK group: IFN-gamma, IL-1, IL-2 and CD3-McAb were added. CFU-GM assay and CD3 phenotype detection were performed before and after activating culture in all groups. The changes of cell quantities during culture and cytotoxicity of cultured cells were tested. CD3 positive cells markedly increased in both CD3-AK and CIK groups. The cell numbers and cytotoxicity of CD3-AK and CIK groups were higher than those of control or IL-2 group obviously after culture (P < 0.05). CFU-GM were decreased in all groups after culture and there had no significant difference among four groups. The combination of IL-2 and CD3-McAb not only stimulates the proliferation of marrow immunocytes and increases their cytotoxicity but retains enough hematopoietic progenitor cells as well. This combination of cytokines can be used to purge autologous bone marrow in vitro.

OBJECTIVETo analyze the clinical characteristics, influencing factors and outcome of recurrent patients with early stage bulky cervical carcinoma.

METHODSBetween January 1(st) 2000 and December 31(st) 2009, 76 patients with stage Ib2 and IIa2 bulky cervical carcinoma developed recurrence and (or) metastasis. The recurrence time, recurrence location, recurrence-related factors, treatment and survival were analyzed.

RESULTSThe median follow up was 44 months (9-137 months). The overall recurrence and (or) metastasis rate was 22.6%. The 1-, 1-2, 3-5 and 5-year recurrence and (or) metastasis rates were 38.2%, 27.6%, 30.3% and 3.9%, respectively. The 5-year survival rate of local recurrence was 34.5%, that of distant metastasis was 23.6%, and that of distant metastasis with synchronous pelvic recurrence was 11.1%, (P = 0.555). The 5-year survival rate of patients who received surgery plus chemotherapy, radiation plus chemotherapy and chemotherapy alone after recurrence and (or) metastasis were 53.3%, 30.7% and 24.6%, respectively (P = 0.686). Univariate analysis demonstrated that tumor recurrence and (or) metastasis in patients of the stage Ib2 and IIa2 bulky cervical carcinoma were influenced by the disease stage, pelvic lymph node metastasis, deep cervical stromal invasion, lymphovascular tumor thrombus and pathological types. Multivariate regression analysis demonstrated that pelvic lymph node metastasis, lymphovascular tumor thrombus and pathological types were the key factors affecting the recurrence and (or) metastases of the stage Ib2 and IIa2 bulky cervical carcinoma. Subgroup analysis showed that pelvic lymph node metastasis and stage were the main factors affecting the local recurrence in those patients, and the pathological type, vascular tumor thrombus and pelvic lymph node metastasis were the main factors affecting the distant metastasis.

CONCLUSIONSRecurrence and(or) metastasis of early stage bulky cervical cancer are mostly happened within 2 years post operation. Patients with pelvic lymph node metastasis have high probability to develop local recurrence and distant metastasis. Patients with non-squamous cell carcinoma and lymphovascular tumor thrombus are more likely to develop distant metastasis. Neoadjuvant chemotherapy does not decrease local recurrence and distant metastasis in patients with stage Ib2 and IIa2 bulky cervical carcinoma. Individualized treatment is advised for recurrent patients.
