Through analyzing the academic ideas in Shanghan Zhinan written by Wei-Ju ZHU, a modern famous physician, it is pointed out that ZHU's achievement on integrative medicine has been overlooked. Taking the theory of syndrome differentiation of six channels from Shanghan Lun as an example, ZHU presumed that the essence of therapeutic theory of traditional Chinese medicine was to conform to or strengthen human body's self-healing and self-regulating abilities. Since Yangqi is the major force in the body to help heal disease when it occurred, ZHU often took measures to strengthen Yang first in treating disease and also was good at using hot-natured herbs, such as Radix aconiti lateralis preparata. ZHU's thoughts on integrative medicine were concerned with etiology, pathology and therapeutics. In addition, ZHU generalized the syndrome differentiation into the theory of five phases and eight principles, and made important contributions to the history of integrative medicine. His thinking will provide valuable revelation for clinical practice and modern research on traditional Chinese medicine.

Objective: To investigate the effects of ω-3 fish oil fat emulsion on nutritional status and humoral immunity in postoperative patients suffering from gastrointestinal malignancy. Methods: Thirty patients of gastrointestinal malignancy were randomly divided into study group (n = 15) and control group (n = 15). All the patients were assigned to receive total parenteral nutrition with the equal nitrogen and calory,and those in study group received fish oil fat emulsion additionally. Liver and renal function, blood lipid, haemoglobin, albumin, transferrin, total lymphocyte count (TLC) , B lymphocyte subsets (B1, B2), immunoglobin(IgG, IgM, IgA) and complement(C3, C4) were determined preoperatively and 1, 6d postoperatively. Results: There were no significant differences in liver and renal function and blood lipid on postoperative day 6 versus preoperation in all the two groups. TLC, IgG, IgM, C3 on postoperative day 6 were siginificantly higher in the study group(P < 0. 05). Haemoglobin, albumin, transferrin and B lymphocyte subsets were not significantly different between the two groups. Conclusion: Fish oil fat emulsion treatment was safe and tolerated, and could improve the humoral immunity in patients.

Sirtuin 1 (SIRT1),the Ⅲ class deacetylation enzyme,is a kind of NAD + dependent histone deacetylation enzyme.The role of SIRT1 in tumor has the duality.It can inhibit inflammation,tumor angiogenesis and interact with tumor related gene to inhibit tumor development.However,it can also regulate tumor related genes,and epithelial-mesenchymal transition,promote tumor cell proliferation and tolerance of radiotherapy and chemotherapy,and maintain the stemness of cancer stem cells to promote tumor proliferation,invasion and metastasis.

Objective:To study the clinical characteristics of odontogenic cutaneous fistula.Methods:6 cases of odontogenic cutane-ous fistula were represented and the reports of 60 cases of the lesion were reviewed.Results:The fistula was mainly located in cheek, chin,para-nasal part,sub-mandibular area and the lower border of the mandible,and respectively corresponding to mandibular third molar,mandibular incisor,maxillary canine,mandibular first and second molar,the corresponding teeth were mainly in mandible (71 .2%).In middle and old aged patients the lesion usually in para-nasal or mandible area,In younger patients the lesion mostly loca-ted in cheek or sub-mandibular area.After root canal therapy for the teeth with apical periodontitis or extraction of none-curable teeth,the odontogenic cutaneous sinus tract disappeared.Conclusion:Proper treatment of focal teeth can cure the odontogenic cutaneous fistulas.

Objective:To study the effects of miR-20a on the osteogenic differentiation potential of inflammatory periodontal liga-ment cells(IPDLSCs).Methods:Cells were isolated and cultured from the healthy and inflammatory periodontal ligament samples (HPDLSCs and IPDLSCs)respectively.miR-20a expression was analyzed by qRT-PCR.Alizarin red staining,Western blot and PCR were used to evaluate the osteogenic differentiation potential of IPDLSCs after transient transinfection of miR-20a mimics or inhib-itor.Results:miR-20a expression in IPDLSCs was lower than that in HPDLSCs,and the osteogenic differentiation potential of IP-DLSCs were promoted by miR-20a mimics,and reduced by miR-20a inhibitor.Conclusion:The miR-20a in IPDLSCs was down reg-ulated.miR-20a can promote the osteogenic differentiation potential of IPDLSCs.

Objective The purpose of this study was to assess the value of serial sectioning and immunohistoehemistry(IHC)for the diagnosis of senfinel lymph node(SLNs)metastases in patients with breast cancer,and to evaluate the significance of mierometastases and isolated tunlor cells(ITCs)in the SLNs. Methods Eighty pailents with clinically node-negative breast cancer underwent SLN biopsy with both99mTc-labeled sulfur colloid and iBosulfan blue dye for SLN identification.All SLNS and non-SLNs were evalnated with standard H&E stain and IHC analysis. Results SLNs were successfully identified in 78 of 80 patients(97.5%),the isotope/blue dye concordanee rate was 76.5%for all SLNs.Thirty two patients (41%)had histologically positive SLNs,and 13(40.6%)of these patients hod SLNS with micrometastatic disease.In 14(43.8%)of these patients,the SLNs were the only nodes involved.The sensitivity,specificity and accuracy of SLN biopsy in predicting axillary node stams were 96.9%,100%and 98.7%,reslaeetively.Patients with positive SLNs metastasis had a markedly higher proportion of non-SLNs metastases compared with those with only micrometastasis in the SLNS(78.9% vs 23.1%). Conclusions Serial sectioning and IHC ale sensitive methods for detecting breast cancer metastases in SLNS.The incidence of non-SLNs metastases is rather low in patients with SLNs that contain only micrometsstatic foci and ITCs.The prognostic significance and effect on surgical management of these occult disease have yet to be determined.

Objective To explore the relationship between G-protein β3 subunit (GNB3) gene C825T polymor?phism and the weight gain of schizophrenics treated with olanzapine. Methods Ninety schizophrenics of first time hospi?talization were collected and treated with olanzapine for 12 weeks. The changes of body weight and body mass index (BMI) were detected before and after 12-week olanzapine treatment. The GNB3 gene C825T polymorphism in patients was determined by polymerase chain reaction (PCR) and DNA sequencing technique. The correlation of GNB3 gene C825T polymorphism and change of clinical parameters was analyzed. Results Body weight and BMI in patients were all increased significantly after treatment (all P<0.01). Weight gain rate (WGR) and increase of BMI in the TT genotype group were higher than those in the CC genotype group (all P<0.01). WGR and increase of BMI in the T-allele carrier (TT and CT genotypes) were higher than those in the T-allele non-carrier (CC genotype) (all P<0.01). There was signifi?cant difference in distribution of genotypes between WGR ≥7% group (CC 15.69%, CT 54.90%, TT 29.41%) and WGR <7% group (CC 38.46%, CT 43.59%, TT 17.95%) (P<0.05). The frequency of T-allele in the WGR≥7% group (63.33%) was higher than that in the WGR<7%group (39.74%) (P<0.05). Multi-variable linear regression indicated that TT genotype (contrasted with CC genotype) was an influential factor for change of body weight after treatment with olan?zapine (β=1.83, standardized β=0.29, P<0.01). Conclusions The GNB3 gene C825T polymorphism is associated with olanzapine-induced weight gain.

Objective:To investigate the correlation between the uterine incisional hematoma following cesarean section and scar diverticulum.Methods:This is a retrospective study involving 1 939 women who underwent cesarean section for the first time at the People's Hospital of Longhua Shenzhen from January 2020 to December 2021. Women with uterine incisional hematoma were selected as the hematoma group ( n=149) and were further divided into the dehiscence group, including patients with uterine incisional dehiscence caused by hematoma, and non-dehiscence group, including those without uterine incisional dehiscence. The patients without uterine incisional hematoma during the same period were selected as the control group ( n=110). The incidence of scar diverticulum after uterine incision healing and the long-term outcomes in the two groups were compared. Statistical analysis was performed using a t-test or Chi-square test. Results:(1) The incidence of uterine incisional hematoma was 7.7% (149/1 939). In the 149 cases with uterine incisional hematoma detected by postoperative ultrasonography, 74 were in the dehiscence group and 75 in the non-dehiscence group. (2) The number of women developing cesarean section scar diverticulum was 41, with an incidence of 2.1% (41/1 939), and all of them were in the hematoma group, accounting for 27.5% (41/149). The proportion of women who developed scar diverticulum in the dehiscence group was higher than that of the non-dehiscence group [52.7% (39/74) vs. 2.7% (2/75), χ2=35.96, P<0.001]. (3) The incidence of scar diverticulum in patients with uterine incisional dehiscence caused by intra-incision hematoma, intra- and posterior incision hematoma, as well as a combination of intra-, anterior, and posterior incision hematoma were 10/18, 55.1% (27/49), and 2/2, respectively. None of the five patients with uterine scar diverticulum were caused by anterior incision hematoma plus partial intra-incision hematoma. The incidence of scar diverticulum was 2.7% (2/75) in the non-dehiscence group. (4) Among the 41 cases with scar diverticulum, ultrasound re-examination by postpartum 6-24 months found that the results of 40 (97.6%) cases were consistent with the last ultrasound findings. A small "v"-shaped scar diverticulum was observed in another patient by ultrasound 42 d after delivery, which disappeared in a re-examination 13 months after surgery. Conclusions:Uterine incisional hematoma is associated with scar diverticulum following cesarean section. Uterine incisional dehiscence due to hematoma may be an influencing factor for diverticulum formation.
