AIM: To investigate the interference of valsartan on blood pressure and plasma angiotensin Ⅱ (ang Ⅱ), aldosterone (ALD) in salt sensitive essential hypertensive patients. METHODS: Eighty-four adult hypertensive patients were enrolled in study, and the salt sensitivity was determined by acute intravenous salt water loading according to Sullvan's criteria. The change of blood pressure and plasma ang Ⅱ, and ALD were compared before and after the treatment. RESULTS: At the end of 2, 4, 6, and 8 weeks, patients with salt sensitive essential hypertensive (group ss) and no salt sensitive essential hypertensive (group nss) were measured. The results showed that sitting systolic blood pressure (SiSBP) was decreased by 17.5 ? 4.3 and 11.0 ? 1.4 mmHg, and sitting diastolis blood pressure (SiDSP) was decreased by 17.0 ? 3.7 and 7.3 ? 1.1 mmHg after the treatment. It was found that patients showed significantly higher plasma ang Ⅱ and lower plasma ALD in group ss and group nss. CONCLUSION: Valsartan can significantly control SiSBP and SiDBP for both groups, interfered plasma angiotensin Ⅱ and I aldosterone, and be more effective for patients with salt sensitive essential hypertensive.

Objective To explore the effect of different hemostatic methods on ovarian function in la-paroscopic ovarian endometriosis cyst enucleation. Methods 200 cases of stage I and II ovarian endometriosis cyst admitted to our hospital from Jan. 2012 to Apr. 2014 were selected. All patients underwent conventional la-paroscopic ovarian endometrial endometriosis cyst enucleation. According to intraoperative hemostasis methods, patients were divided into 3 groups: suture group (n=70), electric coagulation group (n=70), and ultrasonic scalpel group (n=60). Follicle-stimulating hormone (FSH) and antibody forming cells (AFC) on admission and at 1, 3, 6, and 12 months after surgery were recorded. Peak systolic blood flow of ovarian stromal artery (PSV) was also observed. Results FSH for all the three groups were improved compared with that on admission, and the difference had statistical significance (P<0.05). FSH for the suture group was significantly lower than that in the electric coagulation group and ultrasound knife group at 1, 3, 6, and 12 months after operation. The difference had statistical significance (P<0.05). AFC at one month after surgery had no statistical significance between the 3 groups (P>0.05). however, AFC of the suture group at 3, 6, and 12 months after surgery was significantly im-proved compared with those of the the electric coagulation group and ultrasound knife group. The difference had statistical significance (P<0.05). Vaginal type B ultrasonic examination after operation showed that PSV of the su-ture group was higher than that of the electric coagulation group and ultrasound knife group at the second menstru-ation and at the 6-month menstruation after surgery. The difference of PSV between the 3 groups had statistical significance (P<0.05). Conclusion Compared electric coagulation hemostasis and ultrasonic scalpel hemostasis, the suture method can reduce damage of ovarian function in patients with ovarian endometriosis cyst, which is worth to promote.

Objective To investigate the value of the manipulative reduction monitored by ultrasound for the intussusception of children.Methods One hundred and three intussusception children were dynamically observed by ultrasound,and were pressed softly beginning with the head of the intussusceptum,and observed whether there was intestinal peristalsis, and whether the intussuseeptum shortened and disappeared finally.The results were analyzed based on the size of the masse, the length of the intussusceptum,and the patients' age,and compared with the X-ray high pressure air enema.Results Fifty (48.5 ％) intussusception children were recovered.The recoverability was related to the size of the mass, the length of the intussusceptum, and the age of the children (level of cooperation).Thirty-nine patients were recovered after reexamined one hour later.The recoverability of manipulative reduction monitored by ultrasound for the mass diameter less than 2.0 cm was obviously higher than that by X-ray high pressure air enema.Conclusions Manipulative reduction monitored by ultrasound could cure almost half of the intussusception children patients directly.It could decrease the number of patients who were treated with high-pressure air enema,it could relieve the pain of the children and reduce their medical expenses.It also could be acted as a screening way to other therapies like high pressure air enema.

Objective To observe the expression and influence of SH2-B in hepatocarcinoma,and to investigate the molecular mechanisms of canceration in hepatocarcinoma.Methods By using SABC imunohis-tochemistry,the expressions of SH2-B were detected in 27 cases of hepatitis,29 cases of hepatocirrhosis and 47 cases of hepatocarcinoma.Hepatocarcinoma cell (HepG)2 with a low-expressed SH2-B was selected using immunofluorescence assay.There were 3 groups:the transfected group (transfected with pcDNA3.1 -SH2-B), the vector group (transfected with pcDNA3.1 )and the blank group (without transfection).After gene transfec-tion,SH2-B expression was detected by Western blotting;cell proliferation was measured by MTT assay;cell colony was counted by colony formation test;and cell cycle was analyzed by flowcy tometer.Results The posi-tive rate of SH2-B in hepatocarcinoma (95.7%)was significantly higher than 55.2% in hepatocirrhosis (χ2 =1 8.64,P <0.01 )and 25.9% in hepatitis (χ2 =40.01 ,P <0.01 ).After being transfected with pcDNA 3.1 -SH2-B,SH2-B expression dramatically increased in HepG2 cells.After cultured for 48 h,the average optical density value of the transfected group was 1 .1 2 ±0.1 9,obviously higher than 0.45 ±0.1 1 in the vector group (t =-31 .55,P <0.01 ),which indicated that cells proliferation was significantly enhanced after being trans-fected with SH2-B.The cell colony numbers of the transfected group was 1 66 ±1 4,significantly higher than
82 ±8 in the vector group (t =-20.33,P <0.01 )and 78 ±9 in the blank group (t =-1 9.64,P <0.01 ), which indicated that the cell colony numbers increased after being transfected with SH2-B.The S stage cells of the transfected group was (45.7 ±5.8)%,significantly higher than (1 9.4 ±4.7)% in the vector group (t =-20.33,P <0.01 )and (20.5 ±5.1 )% in the blank group (t =-34.69,P <0.01 ),which indicated that SH2-B could enhance promote cell cycle of HepG2 cells.Conclusion The expression of SH2-B in hepatocar-cinoma is high,and it may be involved in the canceration of hepatocarcinoma though promoting cell cycle,cell proliferation and cell transformation.

ObjectiveTo study the changes of cellular immunity caused by intravenous infusion of allogenic rhesus mesenchymal stem cells (MSCs).MethodsMSCs were isolated and cultured.Then the immunomodulatory effects after MSCs infusion were evaluated by means of peripheral blood counts,mixed lymphocyte reaction (MLR) and analysis of lymphocytic subgroup. ResultsMSCs of rehsus were successfully cultivated. No acute toxicities or GVHD were observed in recipients. No obvious changes of peripheral blood counts were present. Recipients A2, A3, A4 were administered with MSC by 4.0 ×105/kg, 1.0 ×106/kg, 2.0×106/kg respectively and relative reaction (RR) of MLR decreased 14 days post MSCs infusion: from 46±2.6 ％to 40.4±1.73 ％ (F =10.19, P =0.023), from (40.9±2.3) ％ to (33±2.1) ％ (F =2.593, P =0.013), from 48.3±2.0 ％ to 39±1.0 ％ (F =28.431, P =0.003) respectively. The decrease degree (ARR) was positively related to the amount of MSCs(F =27.413, P =0.038). RR was restored within 30 days post MSCs infusion. After MSCs infusion, CD3+ CD3+CD4+ and CD3+CD8+ T-lymphocytes decreased in recipient A4, who was administered with the largest number of MSCs, and restored within 30 days. ConclusionMSCs infusion without any other treatment could temporarily inhibit immunity of T lymphocytes in MLR and the immunity inhibition was positively related to the amount of MSCs.The specific immunological characteristics of MSCs were demonstrated with extensive prospect in clinical research.

Objective To understand genomic copy number variations (CNVs) and ascertain karyotype for a 46,X0, + der(?) fetus, and investigate possibility and superiority of array-based comparative genomic hybridization (array-CGH ) in clinical cytogenetic diagnosis. Methods G-banded chromosome analysis was carried out. The whole genome of the fetus was scanned and analysed by array-CGH. The results of array-CGH were confirmed by RT-qPCR. Results G-banded chromosome analysis showed that the fetal karyotype was 46,X0, +der(?). Array-CGH revealed the derivative chromosome as Y chromosome without CNVs. A total number of 118 submicroscopic CNVs were identified. Comparable results between array-CGH and RT-qPCR were obtained for 9 novel CNVs. Conclusion Comparing with conventional cytogenetic analysis, array-CGH is of high resolution, high-throughput and high accuracy, which provides a technical platform for accurate detection of submicroscopic chromosomal aberrations.

OBJECTIVE: To study the effects of long term use of beclomethasone dipropionate (BDP) nasal spray on bone density with perennial allergic rhinitis (AR) in adults. METHOD: A 5-year randomized study was conducted on the effects of BDP nasal spray on serum calcium, phosphorus, alkaline phosphatase, and bone density determined before and after the treatment in 36 adult patients with perennial AR. 20-45 years of age, were randomly divided into 3 groups. That is group A (nasal spray 1 - <3 year), group B (nasal spray BDP 3 - <5 year) and group C (nasal spray BDP > or =5 year). The data were analyzed by paired t test. RESULT: The perennial AR were followed up for more than > or =1 year, > or =3 year and > or =5 year to observe the influences of nasal spray BDP. There were no significant difference between the data examined before and after the treatment (P > 0.05). Bone development is not influenced by nasal spray BDP < or =400 microg/d within 5 years. CONCLUSION Long term use of BDP nasal spray in adult patients does not lead to osteoporosis if the lowest effective steroid dose is given.

Objective: To describe the status of, and to identify the factors associated with, complementary feeding among infants and young children aged 6- 23 months in poor rural areas of Hunan Province, China. Methods: A total of 8 735 infants and young children aged 6- 23 months from 30 poor rural counties in the Wuling and Luoxiao Mountains in Hunan Province were selected by township-level probability-proportional-to-size sampling in August 2015. Questionnaires were used to collect information on the feeding status of the infants in the previous 24 hours, along with personal/family information. The qualified rate of minimum dietary diversity (MDD), the minimum meal frequency (MMF) and the minimum acceptable diet (MAD) were calculated according to the WHO indicators for assessing infant and young child feeding practices. Multi non-conditional logistic regression models were used to analyze factors associated with complementary feeding among infants and young children aged 6- 23 months. Results: The findings indicated that 73.9% (6 452/8 735) of infants and young children aged 6-23 months received the minimum dietary diversity, 81.6% (7 124/8 735) of infants and young children aged 6- 23 months received the minimum meal frequency and 49.0% (4 276/8 735) of infants and young children aged 6- 23 months received an acceptable diet. Compared with the boys, the OR for the MMF and MAD for the girls were 1.15 and 1.11, respectively. Compared with the 6-11 month group, the OR for the MDD for the 12-17 month and 18-23 month groups were 0.41 and 0.38, respectively; the OR for the MMF for the 12-17 month and 18-23 month groups were 1.53 and 2.46, respectively; and the OR for the MAD for the 12-17 month and 18-23 month groups were 0.60 and 0.60, respectively. Compared with the Han ethnic group, the OR for the MDD, MMF and MAD for the Miao ethnic group were 1.43, 1.72 and 1.56, respectively; for the Tujia ethnic group were 2.21, 2.02 and 2.11, respectively; and for the Dong ethnic group were 0.62, 0.61 and 0.64, respectively. When analyzing data related to the children's mothers, compared with women who gestated at the age of 25- 29, the OR for the MMF for women who gestated at less than 20 years of age was 1.59 and at greater than or equal to 35 years of age was 1.33. Compared with women with primary school education or below, the OR for the MDD, MMF and MAD for women with junior high school education were 0.77, 0.74 and 0.80, respectively; for women with senior high school education were 0.67, 0.65 and 0.68, respectively; and for women educated to university level or above were 0.66, 0.47 and 0.60, respectively. Compared with the normal birth weight group, the OR for the MMF for the low birth weight group was 0.71, and for the high birth weight group was 1.30. Compared with the caregivers who provided qualified feeding knowledge, the OR for the MDD, MMF and MAD for the caregivers who provided unqualified feeding knowledge were 1.45, 1.30 and 1.40, respectively. Compared with the breastfed group, the OR for the MDD and the MMF for the non-breastfed group were 0.53 and 0.36, respectively. All P values were <0.05. Conclusion Most infants and young children aged 6-23 months in poor rural areas of China met the MDD and MMF requirements, but fewer met the MAD requirements. The risk factors in infants and young children for complementary feeding included being of female gender, lower in age (months), of Miao or Tujia ethnicity, being born to a mother who gestated at less than 20 or ≥35 years of age, being born to a mother of low education, having a high birth weight, having a caregiver who provided unqualified feeding knowledge and being breastfed.
