OBJECTIVETo introduce the procedure of the 1st ray stabilization combined with resection of the lesser metatarsal heads for patient with severe forefoot deformity caused by rheumatoid arthritis (RA) and evaluate the short to mid-term clinical results.
METHODSFrom Oct. 2006 to Aug. 2010,97 patients (129 feet) aged from 36 to 67 years (average 54), with forefoot deformity caused by rheumatoid arthritis were reviwed. There were 88 males and 9 females,65 single lateral involved and 32 bilateral involved, the average duration of disease was 17 years (6 to 32 years). The 1st ray instability and lesser metatarsophalangeal (MTP) joint stiff dislocation were found in all cases. The first ray stabilization combined with resection of the lesser metatarsal head procedure were performed for all cases. The radiographic Hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measurde and the JSSF (Japanese Society for Surgery of the Foot) score were evaluated before operation and every follow up.
RESULTSThe average followed-up was 37 months (6 to 52 months) for all patients except 5 (7 feet) and 1 died for acute cardiac infarction 1 year after operation. The average JSSF score improved from (33.2 +/- 8.2) points preoperative to (67.3 +/- 3.1) points at final followed-up (P < 0.01); the average HVA was corrected from (50.0 +/- 11.8) degrees preoperative to (21.2 +/- 3.2) degrees at final follow up (P < 0.01); the average IMA was corrected from (15.5 +/- 3.6) degrees preoperative to (9.7 +/- 6.6) degrees at final follow up (P < 0.01). MTP joint nonunion was found in 4 feet. A radiographic high density mass was found in the 1st cuneiform bone during 8 to 11 months followed-up in 3 feet; delayed wound healing was happened in 9 feet; MTP joint infection was happened in 2 feet; tarsometatarsal joint infection was happened in 1 foot; lesser MTP joints deformity recurrence were found in 16 feet.
CONCLUSIONThe characters of forefoot with RA in later stage are the 1st ray deformity and instability compound with the lesser toes deformity. The 1st ray stability procedure which include the 1st MTP arthrodesis and the Lapidus procedure can correct the 1st ray deformities and rebuilt its stability. The lesser toes metatarsal head resection is effective in correct their deformity. This combined procedure is reliable. It is suitable for patients with severe Hallux valgus, increased IMA, tarsometatarsal joint instability and the lesser MTP joint stiff dislocation.

OBJECTIVETo compare the analgesic effect between multimodal and patient-controlled intravenous analgesia(PCIA) in patients with rheumatoid arthritis(RA) in the perioperative period of knee joint replacement.
METHODSFrom June 2015 to June 2016, 40 RA patients undergoing total knee arthroplasty were randomly divided into two groups. There were 20 patients in PCIA group, including 3 males and 17 females, with an average age of(59.6±2.3) years old, who received controlled instillation of sufentanil analgesia controlled by an intravenous analgesia pump. There were 20 patients in multiple model analgesia group, including 2 males and 18 females, with an average age of(56.3±1.3) years old, who were treated with continuous femoral nerve block, local injection of knee joint and combined buprenorphine patches. The VAS score and the incidence of adverse reactions and HSS score were compared between the two groups after operation. The advantages and disadvantages of the two modes of analgesia were evaluated.
RESULTSOn the 6 th and 24 th hours after surgery, the VAS scores of the multimodal analgesia group were significantly lower than those of the PCIA group(<0.01). On the 48 th hour after surgery, the VAS scores was significantly lower in the multimodal analgesia group than those in PCIA group(<0.000 1), both in the state of motion and at rest. On the 1 st week after surgery, the HSS score of the multimodal analgesia group was significantly higher than that in the PCIA group(<0.000 1). The pain score and the degree of activity in HSS score of the multimodal analgesia group were better than those in PCIA group (<0.05). The functional score of multimodal analgesia group was significantly better than that of PCIA group(<0.01). But there was no significant difference in muscle strength scores between two groups.
CONCLUSIONSMultimodal analgesia is an ideal analgesic plan for total knee arthroplasty TKA patients with RA in perioperative period, which has good effects and little adverse reaction.

Objective:To explore the impact of serum carbamoyl phosphate synthase 1 (CPS1) level on prognosis of patients with hepatitis E-related acute liver failure (HEV-ALF).Methods:This retrospective analysis included 100 HEV-ALF patients, 100 patients with acute hepatitis E (AHE) and 100 healthy controls who admitted or underwent health checkup from December 2018 to June 2019 in six hospitals, including the First Affiliated Hospital, Zhejiang University School of Medicine. HEV-ALF patients were divided into non-survial ( n=21) and survival ( n=79) subgroups according to results of 30-day follow-up results. HEV-ALF patients were also divided into the high ( n=50) and low ( n=50) serum CPS1 level groups. HEV-ALF patients were further divided into the improvement ( n=55), fluctuation ( n=32) and deterioration ( n=13) subgroups. The general clinical data from all participants were collected. Serum CPS1 levels were detected by enzyme linked immunosorbent assay. The survival time in the high and low serum CPS1 level groups were presented in the Kaplan-Meier curve. The correlation between serum CPS1 level and HEV-ALF related conventional parameters was also analyzed by linear regression. The efficacy of serum CPS1 level on predicting the 30-day mortality of HEV-ALF patients was estimated by the receiver operating characteristic curve and area under curve (AUC). Results:Serum CPS1 level was significantly higher in HEV-ALF patients than in AHE patients [958.59 (665.52, 1 105.83) pg/ml vs 549.38 (495.02, 649.08) pg/ml, P<0.001], and serum CPS1 level was significantly higher in AHE patients than in healthy controls [549.38 (495.02, 649.08) pg/ml vs 469.89 (373.32, 564.53) pg/ml, P<0.001]. The level of serum CPS1 was significantly lower in the HEV-ALF survival group than in the HEV-ALF non-survival group [922.6 (652.7, 1, 042.3) pg/ml vs 1 252.8 (933.3, 1 555.8) pg/ml, P<0.001]. In addition, the survival time was shorter in the high serum CPS1 level group than in the low serum CPS1 level group [24.59 (22.11, 27.06) d vs 28.16 (26.25, 30.07) d, P=0.045]. Serum CPS1 levels were increased in the fluctuation and deterioration groups [Fluctuation: 1 328.3 (1 184.3, 1 964.0) pg/ml vs 1 245.7 (1 102.0, 1 937.6) pg/ml, P<0.01; Deterioration: 1 483.6 (1 275.9, 1 656.8) pg/ml vs 1 332.2 (1 197.4, 1 509.8) pg/ml, P<0.01], while decreased in the improvement group [810.3 (599.7, 904.5) pg/ml vs 922.6 (679.5, 1 039.6) pg/ml, P<0.01] over time. Besides, a linear positive correlation was found between serum CPS1 level and alanine aminotransferase (ALT) and total bilirubin (TBIL) (ALT: r=0.339, P<0.001; TBIL: r=0.304, P=0.002). The AUC of serum CPS1 level to predict the 30-day mortality of HEV-ALF patients was 0.803 (95% CI 0.666-0.941), the sensitivity and specificity were 66.67% and 97.47%, respectively. Conclusion:Serum CPS1 level was significantly increased in HEV-ALF patients, and closely related to the prognosis of patients with HEV-ALF.

Objective:To investigate the prognostic value of serum free triiodothyronine (FT3) in patients with hepatitis E-related acute liver failure (HEV-ALF).Methods:Clinical data of 88 patients with HEV-ALF and 86 patients with acute hepatitis E (AHE) were collected from the member hospitals of Chinese Consortium for the Study of Hepatitis E between January 2016 and December 2021; the data of 100 health subjects who underwent health check-up in Suzhou Municipal Hospital were also collected as healthy control (HC) group. Serum FT3 levels were analyzed in all subjects. HEV-ALF patients were divided into survival group ( n=73) and death group ( n=15) according to their 30 day survival. Correlation between serum FT3 level and prognosis of HEV-ALF patients were analyzed by Cox regression and orthogonal partial least squares discriminant analysis (OPLS-DA). The receiver operating characteristic (ROC) curve and decision curve analysis (DCA) were used to assess the predictive value of serum FT3 levels for predicting the prognosis of patients, and its prediction efficacy was compared with conventional Model for End-Stage Liver Disease (MELD), King’s College Hospital criteria (KCH) and Child-Pugh models. Results:The levels of serum FT3 in HEV-ALF patients were significantly lower than those in AHE patients and HC group ( P=0.006 or <0.001). Cox regression analysis showed that international standardized ratio ( HR=17.984, 95% CI 2.804-115.362), hepatic encephalopathy ( HR=12.895, 95% CI 2.386-69.695) and total cholesterol ( HR=2.448, 95% CI 1.108-5.409) were independent risk factors for death in HEV-ALF patients, and serum FT3 level ( HR=0.323, 95% CI 0.119-0.876) was a protective factor. OPLS-DA results showed serum FT3 levels had high predictive value. ROC curve analysis results showed that the area under the curve was 0.828 (95% CI 0.733-0.900, P<0.001), the sensitivity was 80.00%, and the specificity was 78.08%. DCA showed that FT3 has good prediction ability and decision-making level serum FT3 levels in patients with improvement and fluctuation were significantly higher than those in the patients with deterioration ( P<0.05 or <0.01). Conclusion:Serum FT3 levels are closely related to the prognosis of HEV-ALF patients and it may be used as a biomarker for the prognosis of patients with HEV-ALF.

Objective To study the characteristics of stress distributions on a customized lingual self-locking orthodontic appliance under transient occlusal force and optimize its structure. Methods A whole 3D model including denture, appliances and wire was established by CT scanning, reverse engineering method and CAD technology; transient nonlinear dynamic analysis on this model during occluding and its structural optimization were conducted, and the optimized lingual appliance was made based on rapid prototyping technology to verify reliability of the finite element model. Results The equivalent stress on the bracket bottom was larger than that on other parts of the bracket; the maximum equivalent stress on the bracket cover was decreased by 60.9% after installing a reinforcing rib on it, which could effectively prevent stress concentration caused by the contact between the arch wire and bracket cover. The simulation results fundamentally agreed with the loading experiment on the bracket cover. Conclusions For lingual orthodontic treatment in clinic, the relative position between interaction points of the occlusal force and brackets should be concerned so as to avoid impairing the self-locking function; through optimizing the appliance design, the elastic potential energy of arch wire can be transferred more effectively to the teeth and reduce losses of the orthodontic force.

Objective: To explore the effect of influenza and 23 valent pneumococcal polysaccharide pneumococcal vaccinations on symptom-improvement among elderly with chronic obstructive pulmonary diseases (COPD). Methods: Data was gathered from 4 communities in 3 National Demonstration Areas set for comprehensive prevention and control of chronic non- communicable diseases in Chongqing city and Ningbo city respectively, from November 2013 to October 2014. The communities were selected by cluster sampling and divided into 4 groups: (1) injected influenza vaccines; (2) injected with pneumococcal vaccines; (3) received both of the two vaccines; (4) the control group that without any intervention measures. All the subjects aged from 60 to 75 were selected to fill in demographic information questionnaire and receive (COPD assessment test, CAT) scores twice, before intervention and 1 year after the vaccination. SAS 9.4 software was used to analyze the change of symptoms and CAT scores before and after the intervention program and comparing the improvement on symptoms among the elderly people under study. Results: A total of 1 244 subjects with nearly same baseline conditions after the propensity score matching, were involved in this study. CAT scores appeared as Median=21 (IQR: 17-26) at baseline. The CAT scores appeared as Median=18 (IQR: 14-24), decreasing in all the 3 vaccinated groups, one year after the intervention program (influenza vaccines, matching t test, t=-6.531, P=0.403; pneumococcal vaccines, Wilcoxon test, H=-9 623, P<0.001; combined vaccine vaccines, matching t test, t=-10.803, P<0.001). However, in the control group, no obvious change was observed (Wilcoxon H=1 167, P=0.403). Proportions of impacts at high or very high levels all decreased in the 3 intervention groups, while little change was observed in the control group. Outcomes from the Factorial analysis suggested that influenza vaccination could improve the general conditions and symptoms including cough, chest tightness, dyspnea, physical activities, and stamina. Pneumococcal vaccination appeared more effective on all of symptoms and indicators. Conclusion: Pneumococcal and influenza vaccination seemed helpful for elderly people suffering COPD to improve the general health condition.
