ObjectiveTo study changes of bone measured with quantitative ultrasound (QUS) in women of Guangzhou area and provide scientific basis for prevention and treatment of osteoporosis (OP).MethodsCalcaneus measurement was done with QUS in 647 women of Guangzhou area, and measurement data was analyzed.ResultsIn menopause and aged women, broadband ultrasound attenuation (BUA) showed a significantly decrease (P<0.01), whereas it decreased only slightly in early postmenopausal women (P>0.05). After the peak of BMD, speed of sound (SOS) showed a stepwise decline, and significantly decrease in menopause (P<0.01), but not significant over eighties (P>0.05). In contrast, stiffness index (STI) significantly decreased from the menopause, and it was a better indicator than BUA or SOS.ConclusionQUS can not only test bone mass but also assess microarchitecture, and it is nonradioactive, cheaper, easier to use, and may play a important role in diagnosis of osteoporosis and women and senile health.

Objective To evaluate the effects of intravenous analgesia with dezocine combining sufentanil in hip and knee arthroplasty for elderly patients.Methods Ninety patients with ASA Ⅱ ～ Ⅲ and aged ≥ 65 years who were scheduled for hip and knee arthroplasty under CSEA and treated with intravenous analgesia post-operation were selected and divided into three group (20 cases):group Ⅰ (sufentanil 2.5μg/kg + droperidol 2.5 mg),group Ⅱ (sufentanil 2.0 μ g/kg + dezocine 10 mg + droperidol 2.5 mg) and group Ⅲ (intramuscular dezocine 10 mg and sufentanil 2.0 μ g/kg + droperidol 2.5 mg),which were diluted to be 100 ml by adding saline.VSA,Ramsay score as well as side effects were recorded at 6,12 and 24 h after operation.75 mg meperidine was administered intramuscularly as rescue medication when VAS was above 5.Results Compared with group Ⅰ and Ⅲ,group Ⅱ showed better outcomes regarding to the VAS and less side effects.Ramsay score 6 h after operation and the amount of patients who needed meperidine in group Ⅲ were higher than those in the other two groups (P ＜ 0.05).Conclusion Dezocine combining with sufentanil in elderly patients underwent low limb arthroplasty shows better postoperative analgesia effects with less side effects,and it's worth for clinical application.

Objective To compare the pharmacodynamics of rocuronium intermittently administered according to body surface area and real body weight and individual differences. Method Forty-two patients undergoing elective surgery under general anesthesia were enrolled into the body surface area group (BSA group) and the real body weight group (RBW group), with 21 patients in each group. The patients in the two groups were induced with 2ED95 of rocuronium according to body surface area and real body weight (16.64 mg/m2 in BSA group; 0.6 mg/kg in RBW group). Whenever T1 recovered to 10%, a dosage of 0.5ED95 was administred repeatedly for 30 min before the end of the operation. The time of neuromuscular blockade and recovery of muscle relaxation were recorded, and the dosage of rocuronium was also recorded. Results No significant difference in each index of neuromuscular block time-effect was found between the two groups (P > 0.05). The single dosage and maintainance amount of muscle relaxation were less in the BSA group than that in RBW group (P < 0.05). Compared with the RBW group, the single dosage, dosing intervals, pharmacological duration and the time TOFr recovered to 0.7 between the different individuals were less in the BSA group (P < 0.05). Conclusion The intermittent administration of rocuronium can maintain the same clinical efficacy according to body surface area as that according to real body weight , with significantly less dosageand reducing the differences of individuals in blockade time-effect of muscle relaxation.

To explore the relationship and possible mechanism of reproductive function of bisphenol A (BPA) with polycystic ovary syndrome (PCOS).Serum specimens were collected from 43 PCOS patients and 37 healthy women.And the level of BPA was detected by enzyme-linked immunosorbent assay (ELISA).The serum level of BPA in PCOS were significantly higher than that in the control group.And the inter-group difference was significant (P ＜ 0.05).The patient level of BPA was positively related with obesity and basic luteinizing hormone (LH) (P ＜ 0.05).In the PCOS group,no significant correlation existed between hyperandrogenemia and non-hyperandrogenemia (P ＞ 0.05).Although no difference existed between insulin and non-insulin resistance,the level of BPA in insulin resistance group was lower than in non-insulin resistance group.A higher level of BPA may be associated with obesity and basic LH in PCOS.

A series of surveillance and management actions was taken to minimize out-of-plan re-operations. These actions include: 1) Building and completing the surveillance and management mechanism against unplanned re-operations; 2) Building a real-time surveillance and reporting mechanism; 3) Enhancing quality control and continuous improvement at the operating departments; 4) Enhancing the supervision on regulations implementation by quality control departments of the hospital; 5) Enhancing quality control for medical records; 6) Building a feedback mechanism for surveillance results; 7) Building a penalty and reward mechanism. Efforts for one year and a half on such surveillance and management proved successful, as the incidence of out-of-plan re-operations fell from 1.7% before these actions to 1.0% afterwards.

Objective To observe the effect of Xijiaodihuang decoction on the release of inflammatory mediators and prognosis in elderly patients with sepsis.Methods A prospective randomized controlled study was conducted. Seventy-four patients with sepsis admitted to the Department of Geriatrics of Changshu Hospital of Traditional Chinese Medicine (TCM) Affiliated to Nanjing University of TCM from March 2015 to February 2017, and they were divided into a TCM treatment group and a control group randomly, 37 cases in each group, there were 2 patients transferred to other department during the period of study to continue treatment, 2 patients discharged automatically and 1 case transferred to other hospital in the TCM treatment group; and there were 3 patients transferred to other hospital, 1 patient discharged automatically, 1 patient dead in 7 days after entering the control group and 1 patient transferred to other department during the period of observation to continue treatment in the control group. Finally, 32 patients were in TCM treatment group and 31 patients in the control group, completing the study. All patients in the two groups received conventional treatment of sepsis, patients in the TCM treatment group took Xijiaodihuang decoction 100 mL concentrated [rhinoceros horn (replaced with buffalo horn) 30 g, rehmannia root 24 g, peony 12 g, tree peony bark 9 g] taken orally or by nasal feeding, and patients in the control group received the same amount of normal saline, the two groups were treated 1 time a day for consecutive 7 days to complete 1 therapeutic course, then the treatment efficacy was evaluated in the two groups. The differences of serum interleukins (IL-1β, IL-6), tumor necrosis factor-α (TNF-α), white blood cells (WBC), C-reaction protein (CRP), lactate levels between the two groups were compared before treatment and on the 3rd, 7th and 14th day after treatment, the incidence of staying in intensive care unit (ICU), time of staying in ICU and 28-day mortality were also observed. The 28-day survival rate between two groups was analyzed by Kaplan-Meier survival curve.Results After treatment in the two groups, the levels of IL-1β, IL-6 and TNF-α had a tendency of increase at first and then decrease. After treatment for 14 days, the IL-1β was significantly lower in the TCM treatment group than that of the control group (ng/L: 83.27±21.84 vs. 96.73±26.33), the levels of IL-6 and TNF-α in TCM treatment group were obviously lower than those in the control group since 7 days after treatment [IL-6 (ng/L): 48.27±24.13 vs. 62.15±24.34, TNF-α (μg/L): 1.41±0.31 vs. 1.96±0.29]. IL-6 and TNF-α were still lower than those in the control group until 14 days after treatment [IL-6 (ng/L): 29.25±18.57 vs. 56.24±23.61, TNF-α (μg/L) 1.35±0.28 vs. 1.83±0.22, allP < 0.05]. There was no significant difference in WBC and CRP between the two groups before and after treatment (bothP > 0.05). After treatment, the lactate in the control group was gradually decreased, while in the TCM treatment group, the lactate level after treatment presented a tendency firstly decreased and then elevated, and after treatment for 3 days in TCM treatment group, the level of lactate began markedly lower than that in the control group (mmol/L: 1.26±0.43 vs. 2.01±0.59,P < 0.05). The ICU hospitalization rate and ICU length of stay in the TCM treatment group were significantly lower than those in the control group [56.25% (18/32) vs. 83.87% (26/31), (10.2±5.4) days vs. (13.5±5.8) days], and the 28-day mortality was also obviously lower in TCM treatment group than that in control group [9.37% (3/32) vs. 29.03% (9/31)]. Kaplan-Meier survival curve analysis showed that the 28-day survival rate in TCM treatment group was significantly higher than that in control group (P = 0.045).Conclusion Xijiaodihuang decoction can reduce the levels of IL-1β, IL-6, TNF-α and lactate in serum, reduce the incidence of staying in ICU, decrease the time of staying in ICU and improve the prognosis of elderly patients with sepsis.
