Adipose tissue,derived from the mesoderm, consists of adipocytes and stromal vascular fraction.Stromal vascular fraction is a cell population that has not been fully identified, which contains a variety of stem/progenitor cells.Recent studies have indicated that adipose tissue contains a certain amount of hematopoietic stem/progenitor cells to maintain its hematopoietic regeneration potential,but the specific mechanism of regulation is not clear yet.This review is mainly about the research progress of adipose tissue and its relationship with bone marrow microenvironment, providing a new idea for understanding the hematopoietic regeneration potential of adipose tissue.

The statement on the depth of needle insertion is collected from Neiiing (nternal Classic) and Nanjing (Classic of Medical Problems) and the relationship of it is discussed with meridians, diseases, symptoms, location of sickness, qi and blood changes in human body, time, layers of needle insertion, reinforcing and reducing of acupuncture, etc. The factors are explored for the determination of the puncture depth, which provides the important guidance for the depth of insertion, needling sensation, reinforcing and reducing manipulations, acupuncture effect and the improvement of acupuncture efficacy. The complex and mystery of acupuncture technique focus on the control of insertion depth. In clinical practice, the increase of needle insertion depth may not induce the equal increase of efficacy. The depth of needle insertion is rather relevant with stimulation at the effective acupoint in the effective layer.

Objective To observe the clinical efficacy of acupuncture by selecting points from the Lung and Stomach Meridians based on the theory of accumulation in stomach and connection with lung in treating post-infectious cough.Method Ninety patients with post-infectious cough were randomized into treatment group 1, treatment group 2, and a control group. Treatment group 1 was intervened by acupuncture at points from the Lung and Stomach Meridians, treatment group 2 was by puncturing points from the Lung Meridian, and the control group was by oral administration of Compound Methoxyphenamine Capsule. Leicester Cough Questionnaire (LCQ) was adopted for observation before and after intervention, and the symptom and clinical efficacies were compared between the groups.Result The total effective rate was 90.0% in treatment group 1, versus 83.3% in treatment group 2, and 80.0% in the control group. The total effective rate of treatment group 1 was significantly different from that in treatment group 2 and the control group (P<0.05). Regarding cough during the daytime, the total effective rate was 93.3% in treatment group 1, versus 83.3% in treatment group 2 and 76.7% in the control group. The total effective rate in treatment group 1 for cough during the daytime was significantly different from that in treatment group 2 and the control group, and the total effective rate in treatment group 2 was significantly different from that in the control group (P<0.05). For cough at night, the total effective rate in treatment group 1 was 86.7%, versus 80.0% in treatment group 2 and 80.0% in the control group. The total effective rate in treatment group 1 for cough at night was significantly different from that in treatment group 2 and the control group (P<0.05). The LCQ score in treatment group 1 was markedly different from that in treatment group 2 and the control group (P<0.05).Conclusion Acupuncture based on lung-stomach theory is an effective approach in treating post-infectious cough, and this method has an advantage of general regulation.

Objective To investigate the diagnostic value of serum miR-21 andCA199 for pancreatic cancer,and aim to provide a potential diagnostic method for the diagnosis of pancreatic cancer in clinical practice.Methods Detect the levels of CA199 and the relative expression of miR-21 in 134 pancreatic cancer patients,97 benign pancreatic disease patients and 106 healthy subjects from January 2014 to December 2015 in Clinical Laboratory of 263 Clinical Department of Army General Hospital,Evaluate the diagnostic value of single and combined detection of CA199 for pancreatic cancer.The diagnostic values were evaluated by receiver operating characteristic curve,sensitivity and specificity.The area under the receiver operating characteristic curve was compared by the z-score test.Results Compared with healthy control group,CA199 and miR-21 in benign pancreatic disease group and pancreatic cancer group showed significantly increased.Compared with benign pancreatic disease group,CA199 and miR-21 alsoshowed significantly increased in pancreatic cancer group.For discriminating the healthy control group and pancreatic cancer group,the sensitivity and specificity were 77.61％and 69.81％respectively when combination CA199 and miR-21.The AUC of combination CA199 and miR-21 was0.85,it showed significantly higher when compared with CA199 and miR-21 alone(P=0.021,P=0.036).For discriminating the benign pancreatic disease group and pancreatic cancer group,the sensitivity and specificity were 69.40％and 65.98％respectively when combination CA199 and miR-21.The AUC of combination CA199 and miR-21 was 0.78,it showed significantly higher when compared with CA199 and miR-21 alone(P=0.017,P=0.023).Conclusions miR-21 showed certain diagnostic value for pancreatic cancer.Combined with CA199,miR-21 may provide a potential assistant diagnostic method for the diagnosis of pancreatic cancer.

Objective To investigate the long-term programming effects on pubertal reproductive function by immunological challenge in early life. Methods Female Sprague-Dawley rats were administered by endotoxin (lipopolysaccharide, LPS) at a dosage of 50 μg/kg and saline intraperitoneally on postnatal day 3 and 5. Body weight was measured weekly. Puberty onset ( vaginal opening) and oestrous cyclicity were monitored from postnatal day 30. At the age of 6 weeks, bilateral ovariectomy was performed. The histological and morphological change of the ovaries (the thickness of the theca interna and the number of different kinds of follicles) were observed and the immunoreactivity of the ovarian sympathetic nerve markers (low affinity receptor of nerve growth factor, p75NGFR) was evaluated by immune staining. Results Immunological challenge (exposed to LPS) in early life delayed vaginal opening significantly [LPS-treated (40.6 ±0.7) days versus controls ( 38. 6 ± 0. 5 ) days, P ＜ 0. 05], decreased the percentage of normal oestrous cyclicity ( LPS-treated 26. 1% versus controls 66. 8% , P＜ 0. 05 ) , decreased the total number of different types of follicles (primordial follicles: LPS-treated 610 ±47 versus controls 1181 ±57, P ＜ 0. 05; primary follicles: LPS-treated 624 ±41 versus controls 960 ± 30, P ＜ 0. 05 ; preantral follicles: LPS-treated 183 ± 16 versus controls 260 ± 14, P ＜ 0. 05; antral follicles: LPS-treated 32 ± 4 versus controls 79 ± 7, P ＜ 0. 05) and increased the thickness of the theca interna [LPS-treated ( 15. 8 ±0. 4) μm versus controls (11.4 ±0. 3) μm, P ＜ 0. 05]. The immunostaining of p75NGFR was obviously enhanced in the LPS-treated ovaries when compared with that of controls ( P ＜ 0. 05 ) . Conclusions Immunological stress during early critical developmental windows could have long dysfunctional effects on the pubertal reproductive function. It delayed puberty onset, reduced the percentage of the normal oestrous cycles, decreased follicles reserve and increased the thickness of the theca interna which might involve the up-regulation of the local ovarian sympathetic nerve activity.
