Objective To explore the difference of pathogenesis between chronic hepatitis B (CHB) and asymptomatic hepatitis B virus(HBV) carriers(ASCs) in children.Methods Subtracted libraries was constructed by suppression subtractive hybridization (SSH) from peripheral blood mononuclear cell (PBMC) of two groups, beta-2-microglobulin (?_2-MG) was screened as one of differentially expressed genes. Serum was collected from children with CHB and ASCs, the differential expression of ?_2-MG was confirmed by enzyme immunoassay.Results Subtractive libraries were constructed successfully, the differentially expression of ?_2-MG and lactroferrin were up-regulated in CHB children.And the differentially expression of ?_2-MG on the level of protein was confirmed.Conclusion The up-regulation of ?_2-MG in CHB children is involved in the pathogenesis mechanisms.

OBJECTIVETo observe the curative effects of combined therapy with Kangyanling (KYL, a Chinese herbal preparation) and Omeprazole on post-burn digestive dysfunction.
METHODSPatients with post-burn digestive dysfunction were assigned to two groups, the 32 in the treated group, including 18 with acute stress gastrointestinal mucosal hemorrhagic lesion and 14 with toxic enteroparalysis, were treated by KYL plus Omeprazole, and the 20 patients in the control group, 11 with acute stress gastrointestinal mucosal hemorrhagic lesion and 9 with toxic enteroparalysis were treated with Omeprazole alone. The pH value in gastric mucosa was determined before and 12 h after treatment, the hemostasis effects in 48 h, and the anti-paralysis effects in 72 h were observed as well.
RESULTSThe pH value in gastric mucosa of both groups before therapy were all lower than the normal range, it raised after treatment in the treated group (P < 0.05), approaching to the normal range, but with no significant change in the control group. The total hemostatic rate and the anti-paralysis rate was 77.8% and 85.7% respectively in the treated group, and 45.5% and 0% in the control group, all shown statistical significance between groups (P < 0.05).
CONCLUSIONCombined therapy with Kangyanling and Omeprazole has obvious curative effects on post-burn gastric dysfunction.

OBJECTIVETo study the expression of gastrin(GAS) and gastrin releasing peptide(GRP) in patients with gastric cancer and investigate the clinical significance.
METHODSThe expression of GAS and GRP in sixty patients with gastric cancer was detected by using tissue chip technique and immunohistochemical methods.
RESULTSThe positive rates of GAS and GRP were 30.0% and 11.7% respectively in 60 cases with gastric cancer. The positive rates of GAS and GRP were higher in moderately and poorly differentiated cancers than those in well differentiated cancer (P< 0.05). The positive rates of GAS and GRP were significantly higher in mucinous adenocarcinoma and signet-ring cell carcinoma than those in other types of gastric cancer (P< 0.05). The positive expression of GAS and GRP in gastric cancer was correlated with lymph node metastasis (P< 0.05).
CONCLUSIONTissue chip technique is a feasible,rapid,economic and accurate approach for screening clinical tissue specimens on a large scale.

Background With the development of phacoemulsification surgery,the minimization of the size of the incision in order to reduce the damaging of eye tissue and postoperative complications becomes a focus.Objective This study aimed to assess the clinical efficacy of coaxial phacoemulsification type cataract surgery through a 1.8 mm microincision with foldable intraocular lens (IOL) implantation in eyes with age-related cataract.Methods Informed consent was obtained from each patient at the beginning of this study.A serial case observation study was designed.Thirty-two eyes of 32 patients with age-related cataract were enrolled in the Inner Mongolia Autonomous Region People' s Hospital from April 2012 to May 2012,including 8 eyes of grade Ⅱ hard nucleus cataract,16 eyes of grade Ⅲ hard nucleus cataract and 8 eyes of grade Ⅳ hard nucleus cataract.Ocular axial length was measured by an A-mode ultrasonic apparatus,and IOL diopter was calculated using the SRK-Ⅱ formula.Under ocular surface anesthesia,a 1.8 mm clear corneal tunnel incision was made at the 10-11 o' clock position,and then an auxiliary incision was made at the 2 o' clock position.The opaque lens was extracted by routine phacoemulsification.An Akreos MI60 IOL was implanted through the 1.8 mm incision.The time and level of ultrasonic power required for phacoemulsification,postoperative visual acuity and incidence of postoperative complication were assessed.Postoperative examinations were scheduled at 1 day,1 week and 1 month after the surgery.Results All the operations proceeded smoothly.The mean phaco-time was (7.0±3.6) seconds and the mean ultrasonic power level was (15.3 ±6.1)% among the different grades of cataract groups.The number of eyes presenting an uncorrected distance visual acuity of ≥ 0.5 was 18 (56.25%),28 (87.50%) and 30 (93.75%) 1 day,1 week and 1 month after surgery,respectively.The number of eyes with a best corrected distance visual acuity of ≥ 0.5 and 0.8 were 31(96.88%) and 26 (81.25%),respectively,1 month after surgery.Negligible changes were detected in the anterior chamber depths,and no thermal damage was found at the incision during the operation.Conclusions Coaxial phacoemulsification and IOL implantation through a 1.8 mm microincision is safe and effective.Thorough planning and precise execution are necessary.

OBJECTIVETo study the effect of puerarin on angiotensin II type 1 receptor (AT1) and angiotensin-converting enzyme 2 (ACE2) in spontaneous hypertension rat (SHR).
METHODSSHRs, 12 weeks old, were randomly divided into four groups: the model control group (A), the Verapamil group (B), and the two puerarin groups (C and D) treated by low dose and high dose of puerarin respectively. After being treated for 3 weeks, total RNA from tissues of heart, aorta and kidney in rats were extracted and mRNA expression levels of AT1 and ACE2 were determined by RT-PCR.
RESULTSAs compared with Group A, the mRNA expressions of AT1 and ACE2 in heart tissue were lower in Group C, and those in kidney tissue were higher in Group D (all P < 0.05); ACE2 mRNA expression was higher in Group D than in Group C (P < 0.05); no significant differences of the two indexes in aorta were shown among various groups. Besides, mRNA expressions of AT1 and ACE2 in heart and kidney tissue were proved to be positively linearly correlated.
CONCLUSIONHigh dose puerarin could increase the mRNA expressions of AT1 and ACE2 in kidney, while low dose puerarin could decrease them in heart; there might be a feed back correlation between AT1 and ACE2.

OBJECTIVETo investigate the protective effects of Yuyin Ruangan Decoction(YRD, traditional Chinese medicine) on experimental hepatic injury in mice.
METHODSThe mice were randomly divided into control group, model group and YRD low, middle and high dose group(n = 11). By ip injection of D-GalN, CCk or thioacetamide (TAA), three models of hepatic injury mice were established to investigate the effects of YRD through detecting the indexes of liver function in serum and, the content of antioxidant system in the hepatic tissue.
RESULTSYRD could decrease the content of alanine aminotransferase (ALT)and aspartate aminotransferase (AST) in serum and that of malonaldehyde (MDA) in the hepatic tissue, upregulate the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in the hepatic tissue. Furthermore, the above effects were dosedependent in a certain degree. CoNCLUSION: YRD has some protection effects on the model of experimental hepatic injury in mouse.

AIM: To observe the effects of Salvia miltiorrhiza Bge (SMB) on left ventricular hypertrophy(LVH)in spontaneously hypertensive rats (SHR) and the expression of c-fos. METHODS: 18 SHRs in 8 weeks old were divided into three groups at random. SMB or distilled water(1 g?kg -1?d -1)was injected intraperitoneally to two groups for 10 weeks. Systolic blood pressure (SBP) and left ventricular mass index(LVMI)were measured. HE,VG and immunohistochemical staining combined with computed morphometry were used to evaluated the cardiomyocyte size and diameter, the collagen volume fraction(CVF), perivascular circumferential area (PVCA) and c-fos expression in the left ventricular tissue. RESULTS: Compared with 8-week-old rats, the SBP, LVMI, cardiomyocyte size and diameter, CVF, PCVA, c-fos expression increased markedly in the 18th week of SHRs. The LVH stopped and c-fos expression decreased whereas SBP changed slightly in animals treated with SMB. CONCLUSION: Chronic treatment with SMB can inhibit the development of LVH in SHR, which is probably related to the decease of cardiac c-fos.
