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.

ObjectiveTo testify the therapeutic efficacy of acupuncture in treating diarrhea-predominant irritable bowel syndrome (D-IBS) based on brain-gutinteraction.MethodEighty D-IBS patients were randomized into brain-gut interacted acupuncture group (treatment group) and a group with acupoints selected based on conventional syndrome differentiation (control group), 40 in each group. The treatment group was intervened by acupuncture by selecting the thirteen ghost acupoints (invented by SUN Si-miao) plus Tianshu (ST25), Dachangshu (BL25), etc., while the control group was by acupuncture based on conventional point selection, including Zusanli (ST36),Tianshu (ST25), Dachangshu (BL25), Ganshu (BL18), Pishu (BL20), etc., three times a week, and 10 sessions as a treatment course. The clinical efficacies were evaluated after 2 treatment courses.ResultThe two groups were generally equal to each other incomparing each dimension of the Short-form Health Survey (SF-36) before treatment, while the scores were increased after treatment in both groups; the treatment group was significantly superior to the controlgroup in comparing the scores ofrole-physical,bodily pain, general health, vitality, social role functioning, and reported health transition from the SF-36 (P<0.05).ConclusionAcupuncture based on brain-gut interaction can produce a more significant effect in treating D-IBS compared to conventional acupuncture.

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 alteration of left atrial(LA) electromechanical characteristics of patients with hypertensivon and patients with hypertension complicated with paroxysmal atrial fibrillation(PAF). Methods By use of two-dimentional echocardiography and Doppler and tissue Doppler imaging(TDI) techniques,we mensurated and calculated the indexes representing LA structure and systolic and diastolic function and electromechanical characteristics in 30 nornal subjects(group1),25 patients with hypertension lasting less than ten years(group2),24 patients with hypertension lasting more than ten years(group3) and patients with hypertension complicated PAF(group4). Indexes representing LA electromechanical characteristics consisted of the difference in time intervals between the QRS onset and the tricuspid A wave,and the QRS onset and the mitral A wave (DQAT),electromechanical time (P-A),electromechanical time dispersion(P-Ad),the maximum P wave duration,the minimum P wave duration,and P wave dispersion (Pd=Pmax-Pmin) calculated from 12-lead surface electrocardiograms. Results The P-A3 in group 4 was much longer than that in group 1,group 2 and group 3. The P-Ad2 in group 4 was much longer than that in group 1,group 2 and group 3.Conclusion There are prolonged P-A3 and P-Ad2 in patients with hypertension complicated PAF. Some indexes,such as P-A3 and P-Ad2,perhaps can predict the onset of PAF in patients with essential hypertension better.

Objective To explore the relationship between the stromal angiogenesis and growth of the large intestinal carcinoma. Methods The vascular quantitative parameters(, , Sv, TA/BA) of the distal and proximal ends of the carcinoma, the center of the carcinoma, and the intestinal mucosa of distal and proximal ends of carcinoma were analyzed with computerized image. Differentiation degree of tumor cell was observed microscopically. Results Of the 48 cases studied, significant differences( P

Objective To provide the theoretic basis for the clearance of the metastatic lymph nodes in radical operation of colorectal carcinoma(CRC) by means of exploring the relationship between mass size of both tumor and lymph nodes and the rate of lymph node metastasis. Methods A total of 702 lymph nodes from 57 cases of CRC radical operations were divided into 5 groups and each of the lymph nodes was examined. The size of lymph nodes, Dukes' phases, the pathological types of CRC and their metastasis rate were analyzed. Results ① High metastasis rate was found at Dukes' C and D phases of CRC, being 29.93% and 48.12%, respectively. ② The metastasis rates of mucous adenocarcinoma and signet ring cell carcinoma were the highest of all pathological types, being 59 52% and 59.26%, respectively. ③ Metastasis rate of lymph nodes was not correlated with the mass size of tumor, but correlated with Dukes' phase. Conclusion ① Metastasis rate of lymph nodes increases with the growth and infiltration of tumor. ② Metastasis rates of mucous adenocarcinoma and signet ring cell carcinoma are higher than those of well and mid differentiated carcinomas. ③ Metastasis may be suggested for lymph node of CRC more than 5 mm in diameter during operation. However, clearance of lymph node of CRC less than 5 mm in diameter needs further study.
