With acupuncture depth as a perspective, some related issues are discussed in this paper. Firstly, the possible reasons of divergence on needling depth are explained. Secondly, by literature retrieval, the advantages and disadvantages of the clinical efficacy of deep needling and shallow needling are explored, and the essential value of shallow needling is emphasized in promoting acupuncture. Thirdly, due to the placebo acupuncture that led to the controversy of the curative effect of acupuncture, it is crucial to establish a method of modern system of scientific research which should be suitable for the development of acupuncture. Finally, the "cun" in acupuncture is inappropriate to transform into millimeter, and the standardization of acupuncture should focus on the improvement of curative efficacy. From the acupuncture depth, it is clear that there are plenty of problems in acupuncture, which could not only limit the development of acupuncture, but also affect the future of acupuncture.

Salmonella enterica serovar Cerro 87, which was isolated from a commercial egg-producing farm, has a phosphorothioated DNA backbone resulting DNA degradation(Dnd) during the pulsed field gel electrophoresis (PFGE) process. In this research, a gene deletion mutant XTG103 was engineered with the entire dnd gene cluster knocked out by double crossover using vector pKOV-kan, and lost Dnd phenotype corre- spondingly. We regulated the DNA phosphorothioation by heterogenous expression of dnd gene cluster with an isopropyl ?-D-1-thiogalactopyranoside (IPTG) inducible promoter PlacZ.

OBJECTIVE: To evaluate the efficacy of the proprioceptive sensibility reflexotherapy by tendon acupuncture needling at trigger points for patients with proprioceptive disorder of cervical vertigo. METHODS: Seventy-nine patients with proprioceptive disorder of cervical vertigo were randomly assigned into a treatment group (42 cases) and a control group (37 cases). Patients in the treatment group received the proprioceptive sensibility reflexotherapy with tendon acupuncture at trigger points in the neck. And those in the control group were given traditional traction, massage and intermediate frequency electro therapy. All the treatment was given for 2 courses, once a day and 10 days as a course. The cervical vertigo symptom and function, the joint position error (JPE) and stability index (ST) before and after treatment were observed in the two groups and the effects were evaluated. RESULTS: The cervical vertigo symptom and function were improved, JPE and ST decreased after treatment in the two groups (all P<0.05), with better results in the treatment group (all P<0.05). CONCLUSIONS: The proprioceptive sensibility reflexotherapy with tendon acupuncture at trigger points is effective for proprioceptive disorder of cervical vertigo.

Objective To summarize the causes of death and to analyze the risk factors in a surgical intensive care unit (SICU).Methods The relevant information of patients died in the SICU of Xijing Hospital of Fourth Military Medical University in past 15 years (from December 1999 to February 2015) was retrospectively analyzed.The gender,age, reason and date of hospitalization, date of transfer SICU, past medical history, whether or not admitted directly from emergency department, or transferred from other department, operated or not, date of death, the main cause of death, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, the history of undergoing mechanical ventilation, continuous renal replacement therapy (CRRT), or antifungal therapy, as well as the ratio of the patients with body temperature higher than 39 ℃, white blood cell (WBC) count higher than 10 × 109/L, platelet (PLT) count below 100 × 109/L, albumin (Alb) below 35 g/L of two periods, namely from December 1999 to July 2007 (the first period),and from August 2007 to February 2015 (the second period) were compared.The above parameters were compared with those of 201 survivors in SICU, and the risk factors leading to death were analyzed by logistic regression.Results From December 1999 to February 2015, 4 317 patients were taken care of in the SICU.Among them, the number of death was 186, and the mortality rate was 4.3％.In the first time period (from December 1999 to July 2007), the total number of patients was 1 356, and the number of death were 109 (the mortality rate was 8.0％).In the second period, i.e.from August 2007 to February 2015, the number of SICU patients was 2 961, and 77 died (the mortality rate was 2.6％).The difference of mortality rate between the two periods was statistically significant (x2 =66.707, P =0.001).The death rate of patients transferred directly from emergency department in tle first period was 79.8％ (87/109), and it was lower in the second period (51.9％, 40/77, x2 =16.181, P =0.001).The death rate of the patients with blood Alb below 35 g/L in the second period (59.7％, 46/77) was higher than that of the first period (41.3％, 45/109, x2 =6.151, P =0.017).The top three causes of death from December 1999 to February 2015 were sepsis (38.2％), trauma (16.7％), and operation for cancer (14.0％).In the first period, the top three causes of death were sepsis (35.8％), trauma (22.0％),and operation for cancer (13.8％).In the second period, the top three causes of death were sepsis (41.6％), damage of the central nervous system (16.9％), and operation for cancer (14.3％).Top three reasons for SICU admission were trauma (29.03％), abdominal pain (20.97％) and other reasons (18.82％).Top three departments from which the patients were transferred were the emergency department (19.35％), orthopedics department (17.20％), and hepatobiliary department (16.13％).Logistic regression analysis showed that age [odds ratio (OR) =2.025, 95％ confidence interval (95％CI) =1.500-2.734, P =0.000], mechanical ventilation (OR =3.514, 95％CI =1.701-7.259, P =0.001), CRRT (OR =5.604,95％CI =3.003-10.459, P =0.000), body temperature higher than 39 ℃ (OR =1.992, 95％CI =1.052-3.771, P =0.034) were the risk factors of death in SICU patients.Conclusion Sepsis and severe trauma are the leading causes of death in severe SICU patients, to whom with risk factors of death enough attention should be given.

OBJECTIVETo observe microvessel density(MVD), epithelial stromal vascular cuffing(VC) and expression of vascular endothelial growth factor(VEGF) in human cervical carcinomas and to clarify their significance in the invasion and metastasis of cervical carcinoma.

METHODSVEGF and CD34 were stained immunohistochemically (SP) in 57 cases of cervical carcinoma (30 cases of squamous cell carcinoma, 20 of adenocarcinoma 7 of glandular and squamous cell carcinoma), 29 cases of cervical intraepithelial neoplasia (CIN) and 16 cases of normal cervices, meanwhile, MVD and VC were also assayed.

RESULTSThere were significant differences among the above 5 groups for MVD P<0.01 . The VC pattern showed a significant difference between cervical carcinoma and CIN or control group P<0.01). The positive rates of VEGF in normal cervical epithelium, CIN, squamous cell carcinoma, adenocarcinoma, glandular and squamous cell carcinoma were 18.8% 3/16, 82.8% 24/29), 93.3% 28/30), 100% 20/20 and 7/7(100%), respectively. There were significant differences between these cervical lesion groups and the control group(P<0.001). The MVD showed significant differences between the positive pelvic node metastasis and negative pelvic node metastasis P<0.05). There was no significant correlation between the expression of VEGF and the tumor diameter, clinical stage, pathologic grade and pelvic node metastasis.

CONCLUSIONThe expression of VEGF may play an important role in the angiogenesis of cervical carcinoma. Degree of malignancy of cervical carcinoma has a close association with microvessel density.

The classification system of diabetic foot not only helps to assess the wound, but it also can be used to predict the outcome of diabetic foot ulcer in the early stage, dynamically monitor the changes in the wound, and rationally direct the therapeutic schedule. At present, there are diverse systems for classifying the diabetic foot, but none has been internationally recognized. The classification systems can be categorized by time sequence, research objective, or structure type. When one of the classification systems is chosen, it is still very important to take the population, facility, and research type into consideration.

Lactic acid production and antagonistic property of five strains of LAB isolated from piglet intestine were investigated. The results showed that among all strains L5 exhibited the most rapid production and highest amount of lactic acid in the culture. Consequently, the pH in L5 culture showed the fast decline, with the final value significantly lower than those of other cultures. Strain L1 showed the least production of lactic acid and highest pH among all strains. Culture supernatants of the five strains showed different degrees of antagonistic effect against pathogenic E. coli K88, K99, 987P, O141, E1, and S. aureus. When taking out the effect of the acid, the culture supernatants still showed 22%～53% inhibitory effect, suggesting that the bacteria produced other inhibitory substances apart from lactic acid. The inhibitory effect of the culture supernatant was above 92% after heat treatment and above 85% when treated with proteases.
