OBJECTIVETo explore the effect and feasibility of acupuncture in uterine involution after cesarean section.

METHODSSeventy cases of cesarean section in primipara were randomized into an observation group (33 cases) and a control group (37 cases). In the control group, the conventional treatment was adopted after cesarean section. In the observation group, on the basic treatment as the control group, acupuncture was applied at Sanyinjiao (SP 6), Hegu (LI 4), Qihai (CV 6) and Guanyuan (CV 4). In 2 h after operation, acupuncture started, once a day, continuously for five times. The daily height of uterine fundus, daily uterine fundus decreasing degree, postpartum blood loss, lochia duration and ultrasonic B test in 42 days of postpartum were compared between the two groups.

RESULTSThe therapeutic methods of the two groups all promoted uterine contraction. The postpartum height of uterine fundus in the observation group was lower than that in the control group (all P<0.05) and the uterine fundus decreasing degree was higher than that in the control group (all P<0.05). The blood loss in 2 h, 6 to 12 h and 24 to 48 h of postpartum was less than that in the control group (all P<0.05). The lochia duration in the observation group was shorter than that in the control group (P<0.05).

CONCLUSIONAcupuncture promotes uterine contraction, reduces postpartum blood loss and lochia duration and benefits uterine involution after cesarean section.

Testicular germ cell tumor (TGCT) is a most common testicular malignancy with an increasing incidence, and its pathogenesis and mechanisms are not yet clear. The next generation sequencing has become the main tool to uncover the underlying mechanisms of TGCT. The differential gene expressions, gene mutation, predisposing gene-dominated signaling pathways, and changes of the relevant genes in the sex chromosome are largely involved in the occurrence and development of TGCT. Studies on the genomics of TGCT contribute a lot to identifying the pivotal pathogenic genes and paving a theoretical ground for the early screening and targeted therapy of TGCT. This paper summarizes the advances in the studies of the genomics of TGCT so as to reveal thetmechanisms of the disease at the genetic level.

Objective To summarize and discuss the diagnostic and treating experiences of chronic pancreatitis with mass in the head. Methods Eight patients of chronic pancreatitis with mass in the head who were misdiagnosised as carcinoma of head of pancreas were analyzed retrospectively in the past 10 years. Results All the patients exhibited abdominal pain,5 of whom were with jaundice and 3 with anorexia. All the patients were misdiagnosised as carcinoma of head of pancreas before the operation,but the pathology after operation indicated chronic pancreatitis. The pancreaticoduodenectomy was performed in 5 patients,the choledochojejunostomy in 2 patients,while the exploratory laparotomy in 1 patient. After the operations,the abdominal pain was relieved in 7 patients, while 2 patients who accepted pancreatoduodenectomy suffered from pancreatic fistula,1 of whom died in the end. Conclusion It’s hard to differentiate the chronic pancreatitis with mass in the head from the carcinoma of head of pancreas before operation. If the carcinoma of head of pancreas can’t be excluded during the operation,the pancreatoduodenectomy should be performed,while the duodenum-preserving total resection of the head of the pancreas or any intra-drainage operations should be done if chronic inflammation is found in the whole pancreas with a negative result of the biopsy of the pancreas through the needle aspiration.

Based on the counting results from nutrition agar in our study, and compared with another two kinds of coliform bacteria detective plates for dinner and drinking sets which were provided by two manufactures and inspected by China National Health Bureau , we accomplished the detectability test of the Huankai coliform bacteria plates. In our study, 3kinds of cell density were adopted: 10cells/mL, 50cells/mL and 100cells/mL . The results shew that the detectability of Huankai plates basically conformed with that of nutrition agar , and was no evident difference from that of another two kinds of plates. The conclusions were that Huankai plates can completely be used in the inspection and test for conform bacteria.

Objective To investigate the method of directed differentiation dendritic cells from embryonic stem cells(ESC) and to amplify high purity DCS in vitro for immunity therapy.Methods E14 ESC line were generated ESC-derived dendritic cells(ES-DC) in complete medium further supplemented with granulocyte-macrophage colony-stimulating factor(GM-CSF) and interleukin-3(IL-3).ES-DCs was used flow cytometry to determine CD11c,CD80,CD86,MHC-Ⅱ cell surface phenotype. Lipopolysaccharide (LPS) were added to induce the ES-DCs matured. The matured ES-DCs was harvested 24 hours later to be identified with morphology, transmission electron microscopy, analyzed by flow cytometry and compared with the immatured ES-DCs phenotype. The antigen presenting was evaluated by mixed lymphocyte responses.Results The ES-DC had obviously dendritic processes under scanning electron microscope . The immature DCs express low level of CD11c(4.33±0.23)%,CD80 (7.62±0.19) %, CD86 (4.77±1.22) % and MHC-Ⅱ (9.68±0.15) %, but the mature DCs express higher lerve of CD11c(47.36±2.68)%,CD80 (74.4±1.47) %, CD86 (29.77±2.00) % and MHC-Ⅱ (87.56±2.75) %. MLR showed that ES-DCs could effectively stimulate lymphocyte to proliferate.Conclusion These results provide evidence that DCs can be generated from E14 ESC with GM-CSF and IL-3, express high level of CD11c,CD80, CD86, MHC-Ⅱ and can effectively stimulate lymphocyte to proliferate. ES cells may become new origin for DCs which provided the immunotherapy.

Objective To assess the proficiency of water monitoring laboratory at rural, county, and provincial levels in Guangdong province, to ensure the province's drinking water monitoring results accurate and reliable. Methods State quality of certified reference materials as water arsenic, fluoride and chloride of 90 copies each were numbered and distributed to 90 monitoring laboratories in the province for testing, The measurement results of the participatory labs were evaluated through normative values and expanded uncertainty, and were compared with those of robust statistics method. Results All participatory labs had timely feedback of their measurement results. The qualified rate was higher when arsenic was tested by hydride generation atomic fluorescence spectrometry and zinc-new silver salt of sulfuric acid spectrophotometric system, while fluoride and chloride by ion chromatography. The average qualified rates of water arsenic, fluoride and chloride of the province's rural drinking water quality monitoring laboratory were 66% (59/90), 72% (65/90) and 72% (65/90), respectively.Seven participatory labs failed the proficiency testing of all three analytes and unqualified rate was 7.8% (7/90)among the ninety participated monitoring labs. The qualified rates of robust statistics method for arsenic fluoride and chloride were greater than those evaluated by the expanded uncertainty, and large deviations with small sample sizes. Conclusions The testing ability of drink-water monitoring labs in Guangdong province has improved.However, by comparison with the requirements of national quality control and testing skills, there is still a gap. It is suggested that internal quality control be included in routine inspeetion to improve laboratory testing technology.

Objective To investigate the expression and significance of Smad 7,Smurf 1 and Smurf 2 in basal cell carcinoma and squamous cell carcinoma.Methods Biopsy specimens were resected from 14 patients with basal cell carcinoma,19 patients with squamous cell carcinoma and 30 normal controls.Quanti- tative real-time PCR and immunohistochemical techniques were utilized to assess the expression of Smad 7, Smurf 1 and Smurf 2 in these specimens.Results The gray scale for staining of Smad 7,Smurf 1 and Smurf 2 was 166.61?7.11,166.08?8.71,and 166.25?8.15 respectively in basal cell carcinoma,161.66?5.52,166.84?9.27,and 169.98?9.48 respectively in squamous cell carcinoma.The expression levels of Smad 7,Smurf 1 and Smurf 2 were all significantly increased in basal cell carcinoma and squamous cell car- cinoma in comparison with normal controls.Conclusions The over-expression of Smad 7,Smurf 1 and Smurf 2 may interfere with transforming growth factor?signaling transduction pathway through several links,therefore prevent the inhibitory effect of transforming growth factor?on epidermal proliferation,and accelerate the abnormal proliferation in above epidermal tumors.

Objective To observe the influence of coal burning fluorosis on learning and memory ability in rats and reveal its possible mechanisms. Methods Healthy 48 SD rats were divided into control, low-fluoride and high-fluoride group. All rats in fluoride exposed groups were fed with the eom polluted by drying processes with burning coal containing high level of fluoride obtained from the endemic fluorosis area to produce the animal model of fluorosis. The experiment period were 3,6 mouths, respectively. The ability of leaning and memory was measured by Morris test and cholinesterase activity detected by photometric method at 3 or 6 month after experiment, respectively. Results Fluoride contents signifieantlly influenced the escape latency, the numbers of crossing the platforms and the time of staying the platforms(the value of F was 29.29,6.47,6.50, respectively, P<0.01).In addition, the numbers of crossing the platforms and the time of staying the platforms were influenced by the exposed time(the value of F was 16.11,45.59, P<0.01). Furthermore, the fluoride contents and the exposed time had an interaction between the numbers of crossing the platforms and the time of staying the platforms (the value of F was 4.67,5.68, P<0.05 or<0.01). Three months after the experiment, the mean values of escape latency [(14.71± 4.85)s] of rats in highly fluoride exposed group were significantly prolonged as compared with controls [(9.28±4.22)s]; 6 month after the experiment, the mean values of escape latency[(12.42±8.03)s, (17.48± 8.05)s] of rats in both groups exposed to fluoride were significantly prolonged as compared to controls [(7.04± 3.29)s, P<0.05]. The decreased numbers of crossing the platforms[(1.62±0.87)number] and the declined time of staying the platforms[(16.70±5.02)s] were found in the rats exposed to high fluoride as compared to controls [(3.53±1.67 )number, (23.33±5.35)s, P<0.05]. The fluoride contents obviously influenced the activities of acetylcholinesterase and butylcolinesterase (the value of F was 12.83,13.27, P<0.01). On the other hand, the times of breeding also influnced the activities of butylcolinesterase (the value of F was 16.26, P<0.01). In 3 months of the experiment, the activities of butylcolinesterase [(0.55±0.12)kU/g] in low fluoride exposed group were significantly decreased in comparison with controls[(0.73±0.10)kU/g, P<0.05]. The activities of acetylcholinesterase[(0.62±0.42)kU/g] and butylcolioesterase[(0.58±0.10)kU/g] in high fluoride group were significantly decreased as compared to eontrois[(1.41±0.52), (0.73±0.10)kU/g, P<0.05]. The correlation analysis showed that there was a negative correlation between the cholinesterase and the escape latency(r=-0.68, P< 0.01), and a positive correlation between the cholinesterase and the time of staying the platforms(r=0.57, P< 0.01). Conclusions The ability of learning and memory in rats with coal buring fluorosis was decreased, which might be connected to the decreased activity of cholinesterase in a dose-effect correlation.

UNLABELLEDOBJECTIVE To investigate the effect of Nepsilon-(carboxymethyl) lysine albumin (CMLs), a primary advanced glycation end products (AGEPs) isoform in diabetic body, on the function and angiogenesis of adipose tissue-derived stem cells (ADSCs) and the protective effect of Danhong Injection (DH). METHODS Human ADSCs were cultured and separated from human subcutaneous fatty tissue using enzymatic digestion and centrifugation. The morphology was observed using optical microscope and differentiation capacities assessed. Cells were exposed to 5 different interventions respectively for 24 h, i.e., PBS, 60 1 microg/mL BSA, 60 microg/mL CML-BSA, 100 microL/mL DH, and 60 micro./mL CML-BSA +100 microL/mL DH. Their effect on the proliferation, migration, apoptosis, and secretion were observed using WST-1 assay, Transwell assay, Annexin V-FITC/PI flow meter test reagent kit, human VEGF reagent kit, ELISA reagent kit, respectively. The effect on ADSCs angiogenesis was observed by in vitro angiogenesis test.

RESULTSCompared with the BSA group, the capacities of proliferation and migration could be significantly inhibited by CML-BSA, the apoptosis promoted, the secretion of VEGF reduced, and the angiogenesis of ADSCs weakened (P < 0.05). Compared with the blank control group, 100 microL/mL DH could significantly promote the proliferation and migration capacities of ADSCs, inhibit apoptosis of ADSCs, increase the secretion of VEGF, and improve the angiogenesis of ADSCs (P < 0.05). Compared with the CML-BSA group, the inhibition of CML-BSA on the proliferation and migration capacities of ADSCs could be significantly reversed, the promotion of CML-BSA on the apoptosis of ADSCs improved, the secretion of VEGF increased, and the angiogenesis of ADSCs elevated (P < 0.05).

CONCLUSIONclusion CMLs could significantly inhibit the proliferation and migration capacities of ADSCs, promote their apoptosis, and inhibit their angiogeneses, which could be improved by DH.
